Building Permits

A City of Boulder building permit is an official document that authorizes the alteration, demolition, construction, enlargement, movement, repair, removal or replacement of any building or structure, or of any accessory attached to a building or structure.

The city requires building permits to ensure safe building, coordinated development, effective land use and high-quality site planning.
