Change of Occupancy

All businesses new to the city or to a property must receive a certificate of occupancy, which includes applying for a permit and inspection of the space. No new building shall be occupied, nor any change of building use made, until an inspection and a Certificate of Occupancy has been issued by the city.

To begin the process of obtaining a Certificate of Occupancy, visit or contact the 
Building and Zoning Division to discuss what you are planning. This initial contact will provide the resources and information you will need to make your project a success and avoid potential problems, which could cost you time and money.

Contractor Licensing

Any contractor that is working on electrical, heating, air conditioning, or permanent signage projects in Fairfield must be licensed by the Building and Zoning Division before a permit will be granted. You should inquire as to whether the contractor working on your project is licensed to work in Fairfield and has obtained the proper permits.


You must obtain a permit for all business signage in Fairfield. This includes permanent signs, temporary signs, grand opening or promotional signs/banners, and tents.
