Alert message

Before undergoing any type of work on your property, no matter the nature and size, check with the Building Department if a building permit is required.

It is important to plan your project in advance, especially during summer months, where the Building Department is busier.

To make sure you submit a complete application, pdfdownload the documents and drawings required for permit applications.
