Permit Answers

Questions property owners and contractors actually ask.

Direct answers first. More context second. Where a rule matters, the final production page will cite the current Ontario or municipal source and show the date reviewed.

Permit Answer

Do I need a permit for a basement apartment in Ontario?

Usually, creating a new dwelling unit or legalizing an existing basement apartment involves a building permit because the work can affect life safety, fire separations, exiting, plumbing, HVAC and other Building Code requirements. Zoning and municipal additional-unit rules must also be checked for the property. Electrical work is separate through the Electrical Safety Authority.

BCIN

What does a BCIN-qualified designer actually do?

BCIN is an identification and registration system used for qualified building practitioners in Ontario. For design work within the applicable qualification, a qualified designer reviews and takes responsibility for the design activities they identify. Municipal guidance commonly requires the designer’s name, registration and qualification information, signature and prescribed responsibility statement. A BCIN is not an architect’s stamp, an engineer’s seal or a permit guarantee.

Permit Answer

Can 828 Design just stamp drawings prepared by someone else?

No automatic or rubber-stamp service should be assumed. A qualified designer must perform a real review of the defined design scope and can require corrections, more information or site verification before accepting responsibility. Work that is incomplete, inaccurate, outside qualification or professionally unacceptable can be refused.

Electrical

Does a building permit include the electrical permit?

No. ESA explains that a municipal building permit and an ESA electrical notification are separate. Almost all electrical work requires an ESA notification. The person doing the electrical work files it; if a Licensed Electrical Contractor is hired, that contractor files its notification.

Permit Answer

When might an independent professional engineer be required?

Engineering can be required for structural beams/openings, underpinning, complex foundations, certain commercial or industrial systems, equipment loads and other professional-engineering work. Under 828’s liaison model, engineering opinions, calculations, reports, drawings, letters and seals are issued by the responsible independent licensed engineer or engineering firm.

Permit Answer

Can 828 guarantee that the city will approve my permit?

No. A complete, coordinated package can reduce avoidable deficiencies, but the municipality applies the Building Code, zoning, applicable law and its own review process. Additional information or revisions may still be requested and municipal timing is outside the designer’s control.

Permit Answer

What drawings are commonly needed for a home addition?

A typical addition package can include a site plan, existing and proposed floor plans, exterior elevations, building sections, construction details and zoning statistics. Structural, HVAC, grading, survey, energy or other information may also be required depending on the project.

Zoning

Should zoning be checked before design starts?

Yes. Zoning can control use, setbacks, lot coverage, height, parking and other site standards. Checking early helps identify whether the concept fits the zoning or whether redesign, a minor variance or another approval may be needed.

Zoning

What happens if my proposal does not comply with zoning?

First identify exactly which zoning provisions are not met and whether the design can be revised. If relief is still needed, a minor variance or other planning process may be appropriate. The municipality or Committee of Adjustment—not the designer—decides whether relief is granted.

Permit Answer

Can I start construction while the permit is being reviewed?

Work that requires a permit should not begin until the required permit or approval has been issued. Starting early can lead to stop-work action, redesign, opening completed work for inspection, added cost and enforcement consequences.

Permit Answer

What should I send for an initial permit review?

Send the property address, a plain-language description of what you want to build, any survey or existing drawings, clear photos, relevant city comments/orders and your timing goals. For commercial work, include the existing/proposed use, landlord/base-building information and equipment requirements if applicable.

Permit Answer

Do I need a survey?

Many additions, new houses and site-sensitive projects benefit from or require reliable property-line information. A measured building drawing is not a legal survey. Where boundaries, easements or encroachments matter, an Ontario land surveyor may be required.

Permit Answer

What happens after a permit application is submitted?

The municipality commonly performs intake or prescreening, then plan examiners review the package. They may issue comments or deficiency requests. Revised drawings/supporting documents are resubmitted until the application is approved or otherwise resolved. After issuance, required inspections must be arranged.

Permit Answer

How long does a permit take?

There is no single reliable timeline for every project. Review time depends on the municipality, project type, completeness, zoning/applicable-law approvals, consultant documents, municipal workload and response time to comments.

Permit Answer

Can you help with existing illegal or unpermitted work?

Potentially, after the actual existing condition and municipal history are reviewed. Existing work may need measured drawings, investigation, professional input, correction or removal before it can be accepted. Existing construction is not automatically legalizable as built.

Commercial

Do commercial renovations always need a permit?

Not every cosmetic change triggers a permit, but changes to partitions, exits, fire separations, plumbing, HVAC, structural elements, accessibility or occupancy/use commonly can. A change of use may require approval even where construction is limited.
