Observe, document, and ask good questions
You will walk through your project more often than anyone else, and you will see things. This module is about what to do with that: how to look, what to photograph and how to file it so it is useful in five years, how to raise a discrepancy without directing a trade, and when to ask for a professional's eyes. It is also, deliberately, about what your walk is not. A homeowner's observation is not a municipal inspection, not an engineer's review, and not acceptance of the work, and "it looks fine to me" certifies nothing. Knowing that line is what makes the observation useful.

1. Five things that look like "checking the work" Understand
On a building project, several different people look at the work for several different reasons, and the words get used loosely. The confusion is expensive in both directions: owners who think the inspector's pass means the work is good, and owners who think their own walk-through means something it does not. Here are the five, kept apart.
| Who looks | What they are checking | What it does not tell you |
|---|---|---|
| You: homeowner observation | Whatever you can see, photograph and ask about: progress, deliveries, what the walls contain before they close, whether what is built looks like what was drawn. | It carries no authority to approve work for code and, in the ordinary case, no duty to find defects. It does not certify workmanship, and a walk that finds nothing says only that you found nothing. Your contract, not the walk, is what lets you reject work that does not conform; the walk produces the record that everyone else, including you at that point, will rely on. |
| The design professional: construction observation | Where an architect or engineer is retained for the construction phase, they visit the site at intervals to become generally familiar with progress and quality and to see, in general, whether the work is proceeding in accordance with their documents. The American Institute of Architects' standard owner-architect agreement and general conditions (B101 and A201, 2017 editions) describe the visits in those terms, and state that the architect is not required to make "exhaustive or continuous on-site inspections," as the research for this course reports from AIA's own summaries. The word "observation" is chosen on purpose: "inspection" implies a duty to find every defect. | It does not control how the contractor builds (means, methods, sequences, safety), and it does not replace the inspections the code requires. Field reports record what was observed and known deviations; they are not approvals of everything not mentioned. |
| Third-party inspection and testing | A defined scope, a written report: an energy rater's blower-door test, a geotechnical technician's compaction test, a septic inspector's staged visits, a special inspector where one is required, a lender's draw inspector. | Each checks only its scope. A lender's draw inspector verifies that work billed is in place, not that it complies with anything. A passed blower-door test says nothing about the framing. |
| The building department: municipal inspection | A code official checks specific items at specific hold points (Module 5) against the adopted code. | Passing does not certify quality, workmanship, or conformance to your drawings beyond what the code requires. The inspector is not checking that the sink is where your plan put it. |
| You again, differently: acceptance | A contract act by the owner: signing off punch-list items, agreeing that substantial completion has occurred, making final payment (Module 11). | It is distinct from every inspection above, and it is the one act on this list with contract consequences for you. Walk-throughs during construction are not meant to be acceptance (section 6 says why that needs care); acceptance is done knowingly, at the end, ideally with qualified eyes beside you. |
The most useful thing about a homeowner's observation is precisely that it carries no authority. You are not there to approve. You are there to see, to record, and to put the right question in front of the right person while the wall is still open. An owner who understands that asks better questions than one who thinks they are inspecting, and gets better answers, because the trades are not being judged by someone unqualified to judge them; they are being asked by someone who is paying attention.
2. What a homeowner can usefully photograph, and how to organize it
Photographs are the one thing you can do that no one else on the project will do as thoroughly, because no one else will be there as often or care as much in five years. Builders who write about this describe pre-drywall photos resolving later leaks, finding studs for a heavy shelf, routing a central vacuum pipe, answering an inspector's question, and settling a client dispute about where the lights were supposed to go. The set below is what experienced people take, and when.
| What | When | Why, and how |
|---|---|---|
| Every wall and ceiling, before insulation and drywall | After rough-in inspections pass, before insulation goes in (and again after insulation, before board, if you can) | The single most valuable set. One wide shot per wall, standing in the same spot you would stand later, then close-ups of every box, pipe, blocking and penetration, with a tape measure in frame hooked to a corner or a window jamb so the distance can be read. |
| Utility locations | As they are set | Shutoffs, cleanouts, junction boxes, the panel and its schedule, where the main water and gas enter, where low-voltage runs go. These are the photos you want at 11 pm with water on the floor. |
| Under-slab and buried work | Before concrete, before gravel, before backfill | Plumbing under a slab, the vapor retarder, conduit, drain tile, anything that will never be seen again. Include something for scale and orientation (a wall, a form board with a mark). |
| Foundation before backfill | After waterproofing or dampproofing and drain tile, before the trench is filled | The waterproofing membrane, the drain tile and its stone, where the downspout drains go. Water problems years later start here. |
| Flashing before siding | After windows and doors are set and flashed, before cladding covers it | Every window and door: the laps, the tape, the sill pan, the head flashing. Also the roof-to-wall junctions and any deck ledger. Take them before the siding crew arrives, because the siding crew covers them in a day. |
| Attic framing and truss bracing | After framing, before insulation | Truss bracing, hangers, connections; a reference if a question arises later about what was installed. |
| Deliveries | At the door, before signing (Module 8) | Packaging, labels, damage, the delivery receipt with your note on it. |
| Damage and problems | When you find them | Wide shot for location, close-up for detail, tape for size, and the date. Then into the issue log. |
| Daily progress | Each visit | A few shots from the same spots each time. They are what you will have when a delay dispute turns on what was done by a given date. |
| Inspection cards and results | Each inspection | The card or the posted notice, the inspector's corrections if any. |
How to organize them
A photo that cannot be found, or that cannot be placed, is worth little. The organization that survives is boring and strict:
- Name every file with the date, the location, the direction you were facing, and what it shows:
2026-10-21_bath-north_drain_01.jpg. Phones will not do this for you; a Sunday evening with the week's photos does. - Keep a folder per room or area and per phase (pre-drywall, flashing, foundation), so the pre-drywall set for the kitchen is one folder you can hand to a plumber in 2031.
- Store them in two places: the phone or a drive, and a cloud copy or a second drive. Phones get lost on job sites.
- Add a note where the photo needs one: "tape hooked on the north wall plate; drain centerline reads 30 in." A photo with a tape in it is still ambiguous about where the tape starts.
- Keep them with the as-built drawings and the change orders at closeout (Module 11). They are part of the house's record.
The progress-photo guide in your binder is a checklist of the sets above with a tick for each one taken; it does not store photos, only the record that you took them and where they are. The AIA publishes a short best-practice note on using photography to evaluate on-site work, which describes the same disciplines from the architect's side: AIA best practices: using photography to evaluate on-site work (a PDF on how design professionals use site photographs as a record).
If you are rarely on site
Then someone else takes the photos, and you ask for them in the form above: a wide shot of every wall before drywall with a tape in frame, named by room and direction, sent before the drywall crew arrives, not after. Many contractors will do this if asked early and specifically. If yours will not, assume the pre-drywall set will not exist unless you take it, and get there yourself for that one day if you can.
3. Discrepancies: when the built thing is not the drawn thing
Sooner or later your walk will find something that does not match the plan: a pipe where a cabinet is supposed to go, a window rough opening that looks small, a header that looks different from the detail, a duct through a joist that seems to have a large hole in it. What you do next is the most important discipline in this module, and it has four parts in a fixed order.
- Describe it, measured from something fixed. "The tub drain is at 30 inches from the north wall" is a fact. "The drain looks off" is a feeling. Hook the tape on a corner, a jamb or a stud you can identify on the plan, and write the number down.
- Photograph it with the tape in frame and a wide shot that shows where in the room you are, and name the file.
- Compare it to the drawing, and write down the sheet, the detail and the dimension you are comparing against. Drawings have revisions; note which revision you are holding.
- Ask the right person, in writing, with the photo and the numbers: your contractor if you have one (not the worker on the ladder; their boss), the designer or engineer through an RFI (Module 9) if it is a design question, the trade's owner if you are the coordinator. The form of the question matters and is covered in section 4.
What you do not do is direct the trade to change it. This is partly the means-and-methods line from Module 9 and partly something simpler: you may be wrong. The drain may be exactly where the tub you chose requires it, and the plan in your hand may have been drawn before the model was picked. The pipe through the joist may be in a hole the code allows. The header may have been changed by the engineer in a letter you have not seen. Asking finds this out at no cost. Directing a change that turns out to be wrong costs you the change and the re-change, and a trade who now has a reason not to listen.
Anything structural, anything the permit depends on, and anything in the electrical, plumbing, gas or mechanical systems is not yours to change or to approve, even when you are sure. Raise it, with the photo and the number, to the designer, engineer or contractor, and let the person whose responsibility it is decide. If a trade offers to "just fix it" on your say-so, the answer is that you would like the designer or contractor to confirm first, in writing.
4. The unresolved items list, and how to ask
The issue log
Every discrepancy, every concern and every question that is not answered on the spot goes into one list, the issue log, in the decision and issue logs. One line each: a number, the date, the location, what you observed (with the measurement), the photo file names, the drawing reference, who you asked, who is to answer, the answer when it comes, and the date it was closed. The log is what makes the site meeting's "issues" item (Module 9) a list rather than a memory, and it is what you read before every walk so that last week's open items get looked at again.
Two habits keep it honest. Nothing is closed until the answer is written in the row, even if the answer was "that is correct as built, here is why." And nothing is closed by silence: an item nobody has answered in two weeks is raised again, in writing, with the original date.
How to ask
The question you ask shapes the answer you get. Three forms work well, and two do not.
| Form | Example | Why it works, or does not |
|---|---|---|
| The comparison | "Sheet A2.1 shows the tub drain at about 18 inches from the north wall. It measures about 30. Can you help me understand the difference?" | States the two facts, invites explanation, implies no conclusion. The answer may be "the plan is wrong," "the tub you chose put it there," or "that is intentional, because…" All three are useful. |
| The intent | "Is this what the detail on A5 intends at the window head?" | Asks the person who knows the intent to compare, rather than asking you to judge. |
| The next step | "What does the inspector need to see here, and is it ready?" or "What would you need from me to resolve this by Thursday?" | Moves the item toward closure and tells you what the person responsible thinks the standard is. |
| The reassurance question (avoid) | "Is this OK?" | Invites "yes." A yes to this question records nothing and means nothing. |
| The instruction (avoid) | "You need to move that." | Directs the trade, may be wrong, and can shift responsibility for the change toward you. |
Ask in writing where you can, with the photo attached, even when you have already talked about it. The written question and the written answer are what the issue log holds, and what you will have when the wall is closed.
5. When to request professional review
Some things you see should go past your contractor's answer to someone with professional responsibility: the engineer, the architect, a specialist inspector, or the building department. The list that experienced owners and builders keep is short and worth memorizing.
- Anything structural. A beam, header, post, connection, foundation or framing member that differs from the drawings, that a trade proposes to change ("we can just sister the joist"), or that you simply cannot match to the plan. The engineer, through an RFI.
- Anything that smells like water. Literal smell, staining, damp subfloor, a flashing lap that runs the wrong way, grading that slopes toward the house, a drain that does not drain. Water is the most expensive thing to find later. The designer, a roofing or waterproofing specialist, or the contractor's written explanation, before anything covers it.
- Electrical or gas concerns. Anything that looks or smells wrong is a question for the licensed trade's owner and, if you are not satisfied, for the building department or the utility. Not a question for you to test.
- Anything the inspector flagged. A correction notice or a conditional pass is a professional's finding; make sure you know what it said, that the correction was made, and that the re-inspection happened, before the wall closes.
- Before concrete is placed over anything questionable, because there is no later.
- When a trade says "we always do it this way" about anything in the engineer's or designer's scope. Often true and often fine; still the engineer's decision.
- When a test fails (blower door, duct, compaction, pressure test): what failed, what the fix is, who re-tests.
- Before final payment: an independent walk-through, or the designer's substantial-completion review where one is retained (Module 11).
Who the professional is depends on your team. If you have an architect or engineer retained for construction, these go to them. If you do not, the question for Module 1's role decision becomes concrete here: who, on your project, is the person with professional responsibility you can ask? For many owner-builders the honest answer is "the engineer who stamped the drawings, for an hourly fee," and that fee is usually small next to what it protects. Record each request and its answer in the issue log.
6. The boundary: observation is not acceptance
Two sentences to keep. Your observation cannot certify workmanship or code compliance; you are not qualified to, and nothing in this course changes that. A well-documented walk is a record of what you saw, not evidence that the work complies with anything; what your contract makes of your walk-throughs is for the contract and an adviser. And your saying "it looks fine to me" during construction is not acceptance of the work; acceptance is a contract act, done knowingly, at defined points, which Module 11 covers.
The first sentence protects you from false confidence. A pre-drywall walk that finds nothing wrong does not mean nothing is wrong; it means you found nothing, which is useful and limited. The second sentence protects you from being held to a standard you did not mean to set. Owners sometimes worry that pointing at a wall and saying "looks good" has approved it. In general it has not, but contracts and jurisdictions differ on what counts as acceptance, and the safe habit is to keep the two acts separate: during construction, you observe and ask; at the end, you accept, in writing, item by item, with qualified help where it matters.
This module teaches how to look and how to ask. It does not make your walk-through an inspection, your photographs a certification, or your silence an acceptance. What a walk-through means under your contract, and what acceptance requires in your jurisdiction, are questions for the contract and an adviser; the course's advice is to keep observation and acceptance visibly separate so that the question rarely arises.
7. See it: the Birch Lane pre-drywall walk See it
The Birch Lane addition from Modules 5 and 9: owner M. Reyes, contractor D. Tollan of Tollan Framing for the shell, with the owner holding the plumber's contract. It is Wednesday, October 21, 2026. The windows are still a week out (Module 9), the electrician has nearly finished the rough-in, and the plumber set the bathroom rough-in and the tub on Monday and Tuesday. Nothing has been inspected yet and nothing is covered. The owner walks the addition after the crew leaves. The same walk is issue I-02, decision D-03 and RFI-03 in the logs tool. Names, dates and numbers are invented.
The walk
The owner starts with the routine from section 2: a wide shot of each wall of each room from the doorway, then close-ups along each wall with the tape hooked on a corner or a stud marked on the plan. In the bathroom, the plan (sheet A2.1, the bathroom plan the designer issued with the permit set) shows the tub drain at about 18 inches from the north wall. The drain line through the floor framing measures about 30 inches from the north wall. Twelve inches off.
Looking down into the floor framing where the pipe passes through, the owner sees something else: the drain runs through a notch cut in the top of a joist, close to where that joist bears on the beam under the bathroom. The owner does not know whether a notch there is acceptable, and knows that not knowing is the point.
What the owner does, in order
- Measure and photograph. Four photos: a wide shot of the north wall from the doorway; the drain with the tape reading 30 from the north wall; the plan sheet with the 18-inch dimension circled; and a close-up of the notched joist with the tape across the notch and the beam in frame. Files named
2026-10-21_bath-north_drain_01.jpgthrough_04.jpg. - Write the issue. Issue log item I-02: "Addition bathroom, north wall, floor framing. Pre-drywall walk: the tub drain runs through the floor framing about 30 in. from the north wall; the plan shows it at about 18 in. The pipe passes through a notch in a joist close to where the joist bears on the beam. I do not know whether that is acceptable; I am asking. Photos 01 to 04, tape in frame. Type: discrepancy. Needs professional review: designer or engineer."
- Ask the responsible people, in the comparison form. The owner emails Tollan's lead that evening, and copies the plumber because the owner holds that contract: "A2.1 shows the tub drain at about 18 inches from the north wall; it measures about 30. The line passes through a notch in the joist near the beam. Can you help me understand the difference, and whether the notch is something the engineer needs to see, before anything is covered?" The owner does not say "move it," and does not say "that joist is cut too deep," because the owner does not know either.
- Do not decide, and do not let anyone else decide by default. The owner adds a line to the email: insulation and drywall on that wall wait for the answer.
What came back
The plumber replies first: the tub the owner confirmed on October 16 has its drain where the manufacturer's installation sheet puts it, and that is not where the designer's drawing assumed, which was drawn from an earlier spec sheet before the model was chosen; the drain had to move to meet the tub, and the joist was notched to get the line through. Tollan's lead replies next: the notch near the bearing point is a question for the engineer, not for the plumber or the contractor, and Tollan sends RFI-03 to the designer and the engineer the same day, with the owner's four photos attached, asking whether the drain location and the notched joist are acceptable as built or need a repair detail, and noting that drywall on that wall is held.
The owner records decision D-03 on October 21: no field change to the drain line until the RFI is answered. The options were written down with it: let the plumber move the drain back to the plan location now, which cuts another joist; accept it as built, which nobody on site is in a position to do until the engineer has looked; or hold, send the RFI, and keep drywall off that wall while insulation elsewhere continues. The log's note to self is the one to copy: "Ask for the answer in writing; do not let 'the engineer said it is fine' pass by phone."
As of the next site meeting, RFI-03 is awaiting its answer. That is a normal state for an issue to be in, and the discipline is in what happens meanwhile: the wall stays open, the photos are filed, and the item is on the meeting agenda with its date. Whatever the engineer answers, the next steps follow from the answer and not from anyone's preference: a written "acceptable as built" goes into the issue log and closes it; a repair detail becomes a change order with its cost and its schedule effect, and a conversation about who pays, which belongs to the contracts and not to the walk-through; a relocation is the plumber's work, after the engineer has said where the line may go. Note that the inspections ahead could not be relied on to settle this: the plumbing inspector checks the plumbing against the code; the framing inspector may or may not look at a notch near a bearing point, and whether a notch meets the code's limits is a different question from whether the engineer's design still works with it; neither inspection checks whether the tub is where the owner's plan put it, and neither replaces the engineer's answer.
The other ending
Suppose the plumber had said, on site, "It's fine, we do that all the time; I'll put a plate on it," and Tollan's lead had agreed. That is two professionals' opinion and it may be right. The owner's move is still not to argue it. It is to ask one more question in the comparison form: "Understood. Because the notch is near where the joist bears on the beam, can you confirm in writing that the engineer has seen it, or send the RFI so we have the answer on paper before the wall closes?" If the answer is a written yes from the engineer, it goes in the issue log. If the answer is a shrug, the owner sends the photos to the engineer directly, and says so. At no point does the owner direct the plumber, and at no point does the owner accept the work by saying it looks fine.
8. Practice: a documented walk, and your issue log Practice
Time: about 60 minutes. Open the progress-photo guide and the decision and issue logs.
- Walk something. If your project is underway, walk the site with the photo guide's list for the current phase. If it is not, walk your existing home as if it were under construction: the utility room, the panel, the shutoffs, the attic hatch, the exterior at the windows. The point is the routine, not the subject.
- Take the set. A wide shot of each wall from the doorway, then close-ups with a tape hooked on something fixed. Photograph the panel schedule, the shutoffs and the cleanouts if you can find them.
- Name the files tonight with the date, the room, the direction and what the photo shows, and put a copy in a second place. Tick the sets in the photo guide and note where the files are.
- Find one discrepancy or one question. On a real site, there will be one. In an existing home, use something you do not understand (a pipe you cannot trace, a junction box with no cover, a stain). Measure it from something fixed, photograph it, and write it as an issue-log line with the comparison-form question you would send and the person you would send it to.
- Write the review triggers for your project into the issue log's notes: who your "professional review" person is for structural, water, electrical and gas questions, and what each costs to ask. If the answer is "nobody," that is a Module 1 finding and a gap to close before construction.
Then check against the criteria in Check your work.
9. Your project Your project
10. Check your work Check your work
Criteria
- Every photo is named with the date, location, direction and content, and exists in two places.
- Every pre-drywall wall has a wide shot and close-ups with a tape in frame hooked to a point you can identify on the plan.
- Every discrepancy is written with a measurement from a fixed reference, a photo file name and a drawing reference including the revision.
- Every question is in the comparison, intent or next-step form, sent in writing to the right person, and logged with the date.
- No issue is closed without the answer written in the row; no issue is closed by silence.
- You can name the person who gives professional review on your project for structural, water, electrical and gas questions.
Worked example: one issue-log line, done fully
| Field | Birch Lane issue I-02 |
|---|---|
| Number and date | I-02; Wednesday, October 21, 2026 |
| Location | Addition bathroom, north wall, floor framing |
| Observed | Tub drain through the floor framing about 30 in. from the north wall (tape hooked on the north wall plate); the line passes through a notch in a joist close to where the joist bears on the beam |
| Photos | 2026-10-21_bath-north_drain_01.jpg to _04.jpg, tape in frame; 03 is the plan sheet with the 18 in. dimension circled, 04 is the notch with the beam in frame |
| Drawing reference | A2.1, bathroom plan, permit set: tub drain about 18 in. from the north wall |
| Type; needs professional review | Discrepancy, drawing versus built; designer or engineer (the notch is in a framing member, so it is the engineer's question) |
| Raised with | Tollan's lead, with the plumber copied, by email Wed evening: "Can you help me understand the difference, and whether the notch is something the engineer needs to see, before anything is covered?" |
| Response | Plumber: the confirmed tub model's drain location required the move. Tollan sent RFI-03 to the designer and engineer Oct 21 asking whether the location and the notched joist are acceptable or need a repair detail. Drywall held on that wall (D-03). |
| Status | Awaiting response; on the Oct 26 meeting agenda with its date; closes only when the engineer's written answer is in this row |
Common mistakes
- Photographing without a reference. A pipe in a wall with no tape and no identifiable corner is a pipe in a wall. Hook the tape; include the corner.
- Asking the worker instead of the responsible person. The plumber on the ladder cannot speak for the contractor and should not be put in that position.
- "Is this OK?" It gets a yes, and the yes means nothing.
- Directing the fix. Even when you are right, the change can now be argued to be yours, and when you are wrong it is yours twice.
- Treating a passed inspection as a quality check. The inspector checks the code's items. The sink location, the finish, the match to your drawings are not among them.
- Closing an issue by forgetting it. Open items get re-raised with their original date until an answer is written down.
- Saying "looks great" and thinking it was harmless. It usually is, but keep observation and acceptance visibly separate so you never have to find out.
What is still unresolved after this module
- Who provides professional review on your project, at what cost, for each category of concern: structural, water, electrical and gas, and inspector findings.
- What your contract says about walk-throughs, acceptance and the owner's right to reject nonconforming work: read it, or take it to an adviser.
- The list of inspections and third-party tests on your permit (Module 5), so you know what each one does and does not check.
- How you will get the pre-drywall photo set if you cannot be there that day.
- What acceptance will consist of at the end (Module 11): punch list, substantial completion, final payment, and who walks with you.
