2. Shall be limited to one (1) sign for each principal entrance;

Full Breakdown

Pittsburgh's zoning code treats home occupations as invisible from the street: § 912.05.B.2 bars any exterior sign for a home-based business except the one sign required by licensing regulations. That sign is governed separately by § 919.03.L, which caps it at 4 square feet, limits it to one per principal entrance, allows wall-mounting that projects no more than 12 inches or a freestanding pole sign no taller than 10 feet set back at least 5 feet from the lot line, and requires it stay nonilluminated. The home occupation itself must also hold an occupancy permit issued under § 912.05.D.

Violations & Fines

Any sign beyond the one licensing-required sign violates § 912.05.B.2's exterior-appearance ban and can trigger enforcement by Permits, Licenses and Inspections; home occupation occupancy permits are non-transferable and end at sale.

Frequently Asked Questions

Can I put up a sign advertising my home-based business in Pittsburgh?
No, beyond the single licensing-required sign. § 912.05.B.2 bans all other home-occupation signage, and that one sign is capped at 4 square feet under § 919.03.L.
Can a home occupation sign in Pittsburgh be lit at night?
No. § 919.03.L requires home occupation signs to be nonilluminated regardless of whether they're wall-mounted or a pole sign.
