The Town of Newmarket Planning & Building Services has adapted its processes to be able to continue to provide services during the COVID-19 pandemic while respecting the health and safety of customers and staff. 

Due to the pandemic, Building Division staff have been working remotely accepting and processing Building Permit applications. Due to the large influx of applications and our recent transition to a new Permitting solution, we are experiencing delays in processing Building Permits. Your application is important to us and we thank you for your understanding and patience. Please see details here.

​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.
