- Building Permits
Proposals to construct, reconstruct, enlarge, alter, or demolish a structure require a permit prior to starting the project. There are a variety of permit-types that may be required for any residential project. Depending on the scope of the project, more than one permit may be required.
Learn about the different types of permits below and review the various types of projects that require a permit. NOTE: Construction that begins before the requisite permit is approved by the Building Official will result in the permit fee being doubled.

A Demolition Permit is required any time a structure is being razed and returned to original grade. This includes all demolition on houses, detached buildings, commercial structures, etc.
The demolition permit is not intended for the removal of interior walls (renovation work).
For the Demolition Permit, the homeowner/contractor shall complete a Building Permit Application. The structure may be assessed by the Building Official to determine if any other action is required.
The permit holder is responsible for notifying the Building Department when the demolition is complete. An inspection will be made to confirm that the demolition is complete, all demolition debris is removed, and the grade has been restored to the point where the land will drain.
