Casa Grande, AZ Home Business: Zoning & Home Occupation Permits (2026)

Casa Grande treats a home occupation as an accessory use to a residence, one that Chapter 17.68, Article III of the zoning code requires to stay compatible with the residential character of the neighborhood. No one may operate a home business before obtaining a permit under § 17.68.190; the application goes to the Planning and Development Director on a city form, with a fee set in the consolidated fee schedule under § 1.04.170. Section 17.68.195 then imposes the substantive limits: the business must be run only by residents of the dwelling unit, with no employees who don't live there; it cannot occupy more than twenty-five percent of the gross floor area of one floor of the home; it cannot require interior or exterior alterations beyond what a normal single-family residence would have; and it cannot increase utility use, such as water, sewer or garbage service, beyond what's normal for the neighborhood.

There is to be no outside storage tied to the business, traffic and parking may grow by no more than one additional vehicle at a time, and the operation cannot generate noise, dust, vibration, odor, smoke, glare, electrical interference or any other nuisance beyond what a normal residence in the district would produce. Signage is capped at one wall sign of two square feet. A local historic landmark can get relief from these standards through a conditional use permit under § 17.68.185, reviewed first by the Historic Preservation Commission.

The Director can order a home occupation terminated on a citizen complaint upon finding the use incompatible or disruptive, and the operator can appeal that termination to the Board within fifteen days.
