The building division provides the community with a source of knowledge and expertise in the review of building plans and the inspection of building projects to safeguard health, safety, property and public welfare. The Department continually strives to improve professionalism and knowledge, to better serve the community.
Most construction projects will require a permit; unless specifically exempted by Section 105 of the International Residential Code or International Building Code.
