Re‐roofing in Agoura Hills requires a permit from Building and Safety and involves two inspections. The
first is a roof nailing inspection, where an inspector will inspect the nailing pattern of the roof deck and a
final inspection, to ensure the job was completed. The City has no minimum requirements on the type
of product to be installed and follows California’s 2007 Uniform Building Code. However, if you are part
of a Homeowners Association there may be restrictions on the particular roofing product or color you
install. For additional information you may contact Building & Safety at 818‐517‐6270 or online at
