Part 3 New Residential Construction

Pre-requisite permits and approvals

Additional permits and documentation may be required before preparing your building permit application, including:

Site plan approval: You must submit an application for site plan approval before applying for a building permit.
Demolition permit: If there is an existing building on your site, you will require a separate demolition permit. A demolition permit is a type of building permit.
Site servicing permit: 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
Halton Region services permit: If adding new connections at the street, a Halton Region services permit is required. Learn more at Halton Region permits.

Zoning

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. Anytime there is a change of use for the building or unit, a Zoning Certificate of Occupancy is required.

Development charges

Development charges will apply to the construction of most new homes. If a structure has been demolished on the same lot, you may be eligible for a development charge credit. Development charges will vary based on the type of home constructed (single or semi-detached, townhouses, apartments). Rates for townhouses and apartments also vary based on the number of bedrooms included.

Learn more about development charges, including current rates.

Fire services

An approved fire route is required. Please contact fireprevention@oakville.ca for more information.

Conservation approval

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.

External agency permits and approvals

In certain instances, approvals from additional agencies are required.

Halton Region: A Halton Region services permit is required.
Ministry of Transportation: If your property is located close to a major highway as indicated in the MTO designated areas map you will require Ministry of Transportation approval.

Other considerations
