The Permits and Inspections Division of the Development Services Department performs the review of all residential and commercial site plan and building plan applications. They issue residential and commercial construction related permits and perform on-site inspections. Our team of building inspectors visit all construction sites within the City to ensure compliance with building, energy, mechanical, environmental, drainage, erosion control, plumbing, electrical, refrigeration, and housing/zoning standards leading up to the final certificate of occupancy.
Please refer to left hand column of this page, there are links to permit applications, contractor licensing, and statistical permit data.
