Non-residential Additions and Alterations

Additional permits or documentation may be required for your project:

• If you are proposing modifications to the site servicing or installing new services, a separate site servicing permit is required. Contact buildingrequests@oakville.ca or 905-845-6601 ext 7377

• If adding new connections at the street, a Halton Regional services permit is required. Learn more at Halton Region permits. 

• If changing the use or occupancy of the space, a zoning certificate of occupancy is required.

Before you get started, consult the zoning by-law to ensure your proposed plans for the unit are permitted under the Town of Oakville's zoning by-laws which regulate the use, shape and location of buildings on properties. 

If changing the use or occupancy of the building or unit, a Zoning Certificate of Occupancy is required. 

Learn more about zoning in Oakville or contact us at 905-845-6601 ext. 3955.

If you are adding gross floor area to an existing building or changing the use of the building, development charges may apply. A non-residential development charge form (pdf) will need to be submitted so the town, region and school boards can review the scope of work and determine if charges apply. Development charges must be paid prior to building permit issuance. If a demolition is involved or an industrial building is being expanded, exemptions may apply. Learn more about development charges and current rates.

If your project is deemed to be substantial redevelopment, then Planning approval is required. Typically, site plan approval is initiated prior to applying for a building permit. 

If you are opening a daycare centre, site plan approval may be required. Learn more about planning applications or contact planningapps@oakville.ca.

If planning alterations to the fire route, please contact fireprevention@oakville.ca.

If your property is in a designated conservation area, contact Conservation Halton for approval at web@hrca.on.ca or 905-336-1158. Learn more about conservation-related permitting and planning.
