Building an outdoor screen room sometimes require a permit. For example, in San Diego, gazebos that are more than 6 feet from another structure and less than 120 square feet in size do not require a permit unless the owners choose to add electricity, such as outlets or lights.
San Diego also sometimes requires permits for structures in the coastal zone that are not required for similar structures in other areas. Building regulations in other cities or counties also vary, so property owners might need the permit even though the structure is small and does not include electricity. Property owners should contact their local building authority before erecting a structure.
