Home businesses in Allegheny County are regulated by municipal zoning under PA MPC authority. Typical home occupation rules: owner-occupied, business subordinate to residential use, no more than 1 non-resident employee, limited customer traffic, no outward signs of commercial activity.
Under PA Municipalities Planning Code (Act 247), municipalities define home occupation as a permitted accessory use in residential districts. Pittsburgh Zoning Code Section 912.04 allows home occupations with conditions: conducted entirely within the dwelling, no more than 25% of floor area, no exterior storage, no external employees beyond one non-resident, no signage except a small name plate, and no customers/clients visiting more often than once per hour during business hours. Most suburban Allegheny County municipalities follow a similar pattern. Some uses (auto repair, kennels, adult businesses) are always excluded.
Zoning violation: $500/day per PA MPC Section 617.2. Cease-and-desist orders issued by municipal zoning officer; appeals to Zoning Hearing Board.
