Building Permit Forms and Information

Due to the Shelter in Place Order issued by the County Health Officer on April 29, 2020 all offices of the Department of Conservation and Development are closed to the public. We continue to operate nearly all of our services and programs while working remotely and supporting the County’s emergency response efforts.

Beginning May 4, 2020 when restrictions on construction are eased by the Shelter in Place Order, we will resume accepting all types of building and planning applications, issuing all types of permits and conducting inspections on all types of construction. However, our process has changed and is now mostly electronic. Please find additional information on how to apply for and receive permits here. Please do not travel to our offices for advice or information as all our buildings and permit centers are not open. We are able to assist you by phone and through electronic communication.

For additional information on how the Shelter in Place has affected our programs and services in the areas of Policy Planning and Housing and Community Improvement please click here.
