New House

A guide to prepare your building permit application.

Plan ahead. Constructing a new home is quite involved and requires coordination of multiple approvals from the town and other agencies. 

Reach out early to involved parties to initiate conversations and allow time for infrastructure upgrades and approvals. 

If you plan to demolish an existing structure, you will require a separate demolition permit. Refer to the Residential Demolition page for more information.

If you plan to create a separate dwelling unit, please refer to the Accessory Apartment page for additional requirements. 

Project preparation

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

Visit our Zoning page or contact us at 905-845-6601 ext. 3955.


One of these three approvals is required for your project:

To build a new house on your property you will need a building permit.

  • Digital copies of drawings and documents are required, scaled to size and flattened. If preparing the documentation is beyond your comfort level or experience, we recommend working with a Building Code (BCIN) qualified designer, architect or engineer.
