Building and Renovating

​The Town of Newmarket's Building Division will assist you with your building projects such as new construction, additions and demolitions. Many projects require building permits which can be applied for at the Municipal Offices.

​​​​The Building Division, under the Development and Infrastructure Commission, is responsible for the enforcement of The Building Code Act and The Building Code Regulations. ​​

Before applying for a building permit, ensure that your intended project conforms to the zoning by-law. Locate the zoning for any property in Newmarket at the "What is my zoning?" page or consult a relevant guide to your type of project in the box below.
