When the City or Committee of Adjustment Asks for As-Built Drawings
A permit can be approved on paper, built slightly differently on site, and still look finished from the street. The problem starts when the city asks, “What was actually built?”
That is where as-built drawings come in. They show the building, addition, deck, basement, garage, or site condition as it exists now, not as it was originally proposed. When a municipality or Committee of Adjustment requests them, it usually means the reviewer needs a clear record before they can close a permit, assess a variance, resolve an enforcement issue, or decide whether the work complies with zoning and building requirements.

What as-built drawings are meant to prove
As-built drawings are not design concepts. They are a measured record of existing conditions.
They may show:
The actual location of walls, stairs, openings, decks, porches, or additions
Actual building dimensions and floor areas
Setbacks from property lines
Finished grades, heights, or lot coverage
Window and door locations
Changes from the approved permit drawings
Existing structural elements where visible or verified
Site features such as sheds, retaining walls, parking areas, or basement entrances
The key word is actual. If the approved drawing showed a rear addition at 4.0 metres deep, but the built addition is 4.3 metres deep, the as-built drawing must show 4.3 metres. Guessing or copying the old permit set defeats the purpose.
A city reviewer may compare these drawings against:
Zoning bylaw requirements
Approved permit drawings
Site plans or surveys
Building Code requirements
Committee of Adjustment decisions
Inspection notes or enforcement orders
The drawings give everyone the same starting point. Without them, the file can get stuck in a loop of comments, unclear measurements, and repeated resubmissions.
Why the city may ask for them
Municipal staff usually request as-built drawings when the built condition is unclear, disputed, or different from the approved plans.
Common triggers include:
A final inspection cannot be closed
An inspector may notice that the finished work does not match the permit drawings. This can happen with basement layouts, decks, stairs, guard locations, secondary suites, or additions.
Work was done without a permit
If construction happened before approvals were in place, the city may ask for drawings that document the existing work. These drawings often become the basis for a new permit application or a review of what needs to be corrected.
A complaint or enforcement file has been opened
A neighbour complaint, property standards review, or zoning concern can lead to a request for measured drawings. The city needs to know what exists before deciding whether the work complies.
The approved design changed during construction
Small field changes are common. Some do not affect compliance. Others do. For example, moving a wall, raising a deck, adding a landing, or changing a roof line may trigger a zoning or building review.
Why the Committee of Adjustment may need them
A Committee of Adjustment deals with minor variances, consent applications, and related planning matters in many Canadian municipalities, especially in Ontario. When a committee asks for as-built drawings, the issue is often zoning.
For example, the committee may need to confirm:
The exact setback from a side or rear lot line
The existing building height
The depth or area of an addition
Lot coverage after construction
The size and location of a deck, balcony, porch, or garage
Whether the existing condition matches a previous approval
This matters because a variance must relate to a specific condition. A request for a 0.6 metre side yard setback is different from a request for a 0.4 metre setback. A committee cannot properly review the relief being requested if the existing measurements are vague.
In some cases, the as-built drawings support a retroactive variance. That means the work is already built, and the owner is asking the committee to approve relief after the fact. This can be more sensitive than applying before construction, because the committee, city staff, and neighbours can see the finished impact.
As-built drawings do not guarantee approval. They simply make the condition clear enough to review.
What a useful as-built package includes
The exact requirements vary by municipality, but a strong package usually includes both building drawings and site information.
A typical set may include:
Drawing or document | What it shows |
Site plan | Building location, setbacks, lot lines, structures, parking, and hard surfaces |
Floor plans | Actual room layout, wall locations, stairs, doors, windows, and dimensions |
Elevations | Exterior walls, openings, grade relationship, and building height where needed |
Sections | Floor levels, ceiling heights, roof forms, and construction relationships |
Details | Specific items such as guards, stairs, openings, beams, or foundations |
Survey input | Property boundaries and legal site information, when required |
If property lines, setbacks, or encroachments are part of the issue, a surveyor may need to be involved. Designers and architects can measure buildings, but they should not invent property line information. A current survey or reference plan may be needed to confirm legal boundaries.
A good as-built drawing set should be:
Clear enough for a reviewer to follow without a site visit
Dimensioned in metric units
Consistent from sheet to sheet
Marked with the date of measurement
Honest about what was visible and what was assumed
Sealed or signed if the municipality requires it
How to respond without making the file harder
The worst response is to send old drawings and hope nobody notices. If the city asked for as-built drawings, reviewers are looking for the current condition.
A better process is simple:
Read the request carefully
Identify whether the city is asking about zoning, building code, permit closeout, or a Committee of Adjustment application.
Gather the existing records
Pull together the permit drawings, survey, inspection notices, site plan, committee decision, and any construction sketches.
Measure the built condition
Measure the relevant areas directly. For complex issues, use a qualified designer, architect, engineer, or surveyor as needed.
Show changes clearly
If the work differs from the approved drawings, show the actual dimensions. Do not hide the difference. Reviewers need clarity to decide what comes next.
Submit a complete package
Partial information often leads to more comments. Include the sheets and details requested, plus the forms or supporting documents the municipality requires.
Be prepared for follow-up
The city may ask for revisions, an engineer’s review, a zoning certificate, or a variance application. That does not always mean the project has failed. It means the file needs a proper path to approval.
This is also the point where professional help can save time. A small measurement error can change the required variance. A missing elevation can delay a final inspection. A site plan without reliable property line information can create more questions than answers.
The main takeaway
When the city or Committee of Adjustment asks for as-built drawings, they are usually asking for certainty. They need to know what exists, where it sits, and how it compares to zoning, permit drawings, and applicable rules.
Treat the request as a chance to clean up the record. Accurate drawings can help close a permit, support a variance, respond to an enforcement issue, or identify what needs to be corrected.
The best as-built drawings are simple, measured, and honest. They do not try to make the project look approved. They show the project clearly enough for the approval process to move forward.
