Maricopa County zoning ordinance prohibits exterior signage for home occupations in residential zones. No exterior display, sign, or other indication of business activity is permitted that would alter the residential character of the property. Home businesses must operate without any visible exterior evidence of commercial use.
Under the Maricopa County Zoning Ordinance (MCZO), home occupations in residential zones are prohibited from displaying any exterior signage, banners, or advertising visible from the street or neighboring properties. This includes illuminated signs, window displays, and vehicle signage parked conspicuously to advertise the business. The intent is to preserve the residential character of unincorporated communities such as Sun City, New River, and Cave Creek outskirts. Violations are handled by the Maricopa County Planning and Development Department Code Compliance Division at (602) 506-3301, which investigates complaints and issues notices of violation with a compliance timeline.
