💰 Quick Cost Summary
As of January 1, 2026, Ottawa building permit fees for renovations are charged at $12.75 per $1,000 of construction value, with a minimum fee of $117. New construction and additions are calculated based on gross floor area using the City’s Service Index.

Understanding Ottawa building permit fees before you start your project helps you budget accurately and avoid surprises. Whether you are planning a basement renovation, deck, home addition, or a brand-new custom home in Ottawa, the City charges specific fees based on the type and value of your construction work.

How Ottawa Building Permit Fees Are Calculated
The City of Ottawa uses two different methods to calculate Ottawa building permit fees, depending on whether your project involves new floor area or is a renovation of existing space:
Renovations & Alterations
For work on existing buildings with no new floor area (basement finishing, kitchen renovations, wall removal, plumbing changes, etc.)
$12.75 per $1,000
of assessed construction value
Minimum fee: $117
New Construction & Additions
For projects that create new gross floor area (home additions, new homes, garages, accessory buildings, etc.)
GFA × Service Index Rate
based on occupancy type & floor area
Minimum fee: $117
If your project includes both renovation work and new floor area (for example, renovating your kitchen and adding an extension), the permit fee is the combined total of both calculations. The construction value includes all materials, labour, overhead, and professional fees for the project.
Renovation & Alteration Permit Fees (2026)
Most Ottawa homeowners dealing with interior renovations, basement finishing, interior renovations, or system upgrades will fall under the construction value method. Here is what typical projects cost in permit fees:
💡 How to Calculate Your Fee: Take your total construction value (materials + labour + overhead + professional fees) and multiply by 0.01275. If the result is under $117, you pay the $117 minimum. Example: A $40,000 basement renovation = $40,000 × 0.01275 = $510 permit fee.
New Construction & Addition Permit Fees
When your project creates new gross floor area — such as a home addition, custom home, or detached garage — the City calculates fees using the Gross Floor Area (GFA) method. The fee is based on the occupancy type and a Service Index rate per square metre.
For residential new construction, the rate works out to approximately $11.40 per square metre (about $1.06 per square foot) of above-grade floor area. Finished basements included in the design are charged at a lower rate of approximately $2.69 per square metre ($0.25 per square foot).
These are approximate estimates based on the City’s published rates. For a precise quote, refer to the official City of Ottawa fee schedule or contact Building Code Services at 3-1-1. For more on architectural drawing costs, see our dedicated pricing guide.

Other Permit Fees & Charges You Should Know
Beyond the basic construction permit fee, Ottawa homeowners may encounter additional charges depending on the project scope. Here are the other fees from the 2026 fee schedule that commonly apply to residential projects:
⚠️ Surcharge Warning: If you start construction before your permit is issued, the City charges an administrative surcharge of 50% of the permit fee (up to a maximum of $10,000) on top of the regular permit cost. This also applies to demolition under heritage or demolition control bylaws, where surcharges of $1,170–$3,510 apply. Always obtain your permit before breaking ground.
What Your Permit Fee Covers
Your Ottawa building permit fees cover the City’s cost of administering the building permit process. This includes:
Plan review — City staff review your drawings for compliance with the Ontario Building Code and zoning bylaws
Mandatory inspections — at key stages of construction (footing, framing, insulation, plumbing, final)
Zoning verification — confirmation that your project meets setback, height, and lot coverage requirements
Permit issuance and record-keeping — official documentation of your approved construction
Permit fees do not cover the cost of architectural drawings, engineering reports, or ESA electrical permits — those are separate expenses. For details on drawing costs, see our Ottawa architectural drawing pricing guide.
Total Permit Costs: Beyond the Fee Itself
While the building permit fee is relatively modest, homeowners should budget for the full cost of the permit process. Here is a realistic picture of what to expect when budgeting for permits on a typical Ottawa renovation or addition:

How and When to Pay Permit Fees
Ottawa building permit fees are due when you submit your building permit application. The City does not accept cash for any Building Code Services transactions. Accepted payment methods include debit card, cheque (payable to the City of Ottawa), bank draft, and money order.
Applications can be submitted online through the My Service Ottawa portal, or in person at one of the City’s Building Code Client Service Centres in Laurier, Nepean, or Orleans. Electronic submission is the preferred method and allows you to pay, upload drawings, and track your application status from any device.
Tips to Save Money on Building Permit Costs
Submit complete, accurate drawings the first time. Incomplete applications lead to deficiency letters, re-examination fees (10% of original fee), and weeks of delay. Professional permit drawings significantly reduce rejection risk.
Never start work before your permit is issued. The 50% administrative surcharge can add hundreds or thousands of dollars to your costs — and you may face fines on top of that.
Be ready for inspections. Failed inspections lead to $100 re-inspection fees each time. Make sure work is complete and visible before booking each stage inspection.
Minimize permit revisions. Changes after your permit is issued trigger revision fees. Finalize your design before applying by working with a qualified architectural technologist.
Development Charges: An Additional Cost for New Construction
If you are building a new home, adding a secondary dwelling unit, or constructing additional residential units on your property, you may also owe development charges — one-time municipal fees that fund growth-related infrastructure like roads, water mains, and sewer systems. These are separate from Ottawa building permit fees and can be substantial.
As of October 2025, Ottawa Council approved a change allowing development charges for residential projects to be paid at occupancy rather than at permit issuance, on an interest-free basis for 18 months. Development charge rates are also indexed annually — a 3.6% adjustment is scheduled for April 1, 2026. These charges typically range from $15,000 to $40,000+ for a new single-detached home, depending on the zone and services available.
💡 Important Distinction: Development charges apply to new construction and conversions only — not to renovations of existing space. If you are finishing your basement or renovating your kitchen, you will not owe development charges. However, if you are converting a single-family home into a legal duplex or adding a secondary suite, development charges may apply. Consult the City of Ottawa’s development charges page for the latest rates.
