When Are Permits Required?

Building Permits

Section 105.1 of the International Building Code 2015 Edition states "Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system…" must obtain a permit before the work is started.

This includes nearly any construction-related project on both residential and non-residential property. Please refer to individual subsections of this website for requirements and fees applicable to specific activities or projects. A separate Fee Schedule is also available.


Upon issuance of a permit, one or more inspections will be required before the work can be considered complete and in compliance with the applicable codes and ordinances. Please refer to Inspection Requests for more information.
