Build or Make an Addition
Additions and extensions increase a building's size or introduce new detached structures to a property. Due to the impact on zoning and structural integrity, these projects always require comprehensive building permits and site plan review.
Please note: We're actively working to add even more permit project content to our new permitting BETA site. Please continue to check back for updates and new content.
