As-Built & Measured Drawings
The service is matched to the actual project, municipality and information available before detailed permit documentation is finalized.
What does this service need to solve?
For most permit and renovation projects, “as-built” work starts with a site measurement and turns the visible existing building into usable plans, elevations or sections. It does not prove what is hidden inside walls, certify legal compliance or guarantee the accuracy of conditions that could not be observed.
Technical permit information must match the project and the professional responsibility being accepted. 828 Design coordinates building-design documentation within applicable scope and identifies when independent regulated professionals are required.
What changes the scope of As-Built & Measured Drawings?
The same project name can require different drawings and approvals on different properties. These four checks help define the real permit problem before the set is developed too far.
Accepted responsibility
The service must match the applicable BCIN qualification or the independent professional taking responsibility.
Existing information
Reliable measurements, base drawings, equipment data or consultant information may be needed before coordination.
Cross-discipline impact
Structural, mechanical, plumbing, electrical and architectural information can affect one another.
Permit integration
Technical sheets need to coordinate with the main permit set instead of being prepared as disconnected documents.
What the project package may need to communicate
The exact documents depend on the property, building, proposed work, municipality and professional scope. A coordinated set should explain the work clearly enough for the applicable review.
Base drawings
Use coordinated architectural or measured information as the reference for technical work.
Technical layouts
Show equipment, systems, structural elements or permit information relevant to the accepted scope.
Schedules & notes
Provide project-specific data and notes required to explain the coordinated permit design.
Sections & details
Use sections or details where plan views alone cannot communicate the condition.
Consultant information
Integrate independent professional input where the project legally requires it.
Permit-set coordination
Check that technical information aligns with the building permit drawings and current project revision.
As-built and measured drawings document visible existing conditions. They do not certify concealed construction or automatically prove that existing work complies with a prior permit.
As-Built & Measured Drawings: project-specific permit considerations
What an as-built drawing or measured drawing can include
Depending on what the next design stage needs, we can document:
- room dimensions, wall locations, doors, windows and stair geometry
- floor plans and selected elevations or building sections
- visible beams, columns, bulkheads and other relevant building features
- plumbing fixtures, mechanical equipment and visible service locations where needed for coordination
- photographic site documentation supporting the measured set
- existing-condition base drawings that can be developed into a permit or renovation package
What “as-built” does not automatically mean
The term is used loosely in construction. 828 Design uses the service for measured existing-condition documentation unless the written scope says otherwise. We do not represent a measured drawing as a legal boundary survey, a concealed-condition investigation, a structural condition opinion or a professional engineer’s record drawing.
Why accuracy depends on access
Locked rooms, finished ceilings, millwork, inaccessible roofs, concealed foundations and wall cavities limit what can be measured directly. Where dimensions are inferred from partial information, the drawings should be treated as design base information and verified when the concealed condition becomes accessible.
Using measured drawings for permit work
Existing-condition drawings are often the foundation for additions, basement apartments, interior alterations, change-of-use projects and unpermitted-work legalization. Once the existing building is documented, the proposed design can be compared against zoning, Building Code and discipline-specific requirements.
How the permit drawing service moves forward
A clear sequence helps separate feasibility, design, documentation and municipal review without implying that any approval result is guaranteed.
Property / Project Review
Review the address, proposed work or use, available drawings and the main zoning/permit questions.
Existing Information
Confirm the measurements, survey/base-building information, photographs or consultant inputs needed for the accepted scope.
Permit Documentation
Prepare and coordinate the drawings and supporting information included in the written service agreement.
Submission / Review
Support the agreed municipal submission or comments process; added revisions and new requirements are handled as separate scope where applicable.
What to send for a project review or quote
Good starting information helps identify the correct service and avoids guessing about the building or property.
- property address and municipality
- what the measured drawings will be used for
- approximate building size and number of levels
- photos or video of the areas to be measured
- existing drawings, survey or permit set if available
- access limitations or occupied/tenant conditions that may affect the visit
The issued permit is the construction reference.
Contractors and owners remain responsible for construction, site safety, inspections and building in accordance with the issued permit documents. Material field changes should be reviewed before they are constructed because revised drawings, engineering or municipal approval may be required.
Connect the project to the right permit services
Use descriptive related-service links to move from the broad project question to the specific zoning, drawing or technical service that applies.

Short answers first, with project-specific limits stated clearly.
Do you need to visit the property?
Usually yes when 828 Design is being retained to produce measured existing-condition drawings. The required level of measurement depends on the project.
Can you use old realtor plans or client measurements?
They can be useful references, but we do not treat unverified third-party information as our own measured site data. If a limited drafting scope relies on client-supplied information, that limitation should be stated.
Are measured drawings the same as a legal survey?
No. Property boundaries and legal survey information are the responsibility of an Ontario land surveyor where a survey is required.
Will the drawings show hidden framing or foundations?
Only if those conditions are visible or otherwise reliably documented. Concealed construction may require opening, investigation or specialist review.
Can the same measured set be used for a permit application?
Often it becomes the existing-condition base for permit design, but the proposed permit package still requires the relevant design and Code information.
Do you certify that the existing building is legal?
No. Existing-condition drawings document what was measured; legality and permit history must be assessed separately against municipal records and applicable requirements.
What information is needed before technical coordination starts?
The required inputs depend on the service but can include architectural base drawings, site measurements, equipment information, existing system data and the current permit scope.
Is professional engineering included automatically?
No. Where Ontario law or the project requires a Professional Engineer, engineer, surveyor or other regulated professional, that professional remains separately responsible for their work.
