Siting/Setbacks. Antenna installations may be mounted to any part of a building or mounted to the ground. No antenna installation shall be located within any front, street side, interior side, or rear building setback area that is required pursuant to the site’s underlying zoning designation. Additionally, in cases where the building has been situated a distance greater than the minimum front or street side setback, no antenna installation shall be located closer to the street than the building. Antennas that are attached to an antenna support structure may encroach into interior side and rear setback areas up to 50 percent of the required setback distance pursuant to the site’s underlying zoning designation. Proposals for antenna installations that do not comply with these provisions shall require an antenna permit pursuant to PMC § 17.31.040.
