Residential Building Permits

Building permits give legal permission to begin construction, subject to other required municipal approvals. Building permits ensure that the proposed construction will meet the minimum life and fire safety requirements contained within the Building Code. Obtaining a permit is the law and allows Building staff to double check the important life safety features for your project.
