Rochester, NY Home Business: Signage Rules (2026)

Rochester's home occupation sign rule splits sharply by district. In the R-1 Low-Density Residential District, the City's largest and most restrictive residential zone, § 120-139G bans home occupation signage entirely: no sign of any kind may advertise the business. In every other zoning district where a home occupation is permitted, an operator may display exactly one sign, and it must meet all of the section's conditions at once: it cannot be illuminated, it cannot exceed one square foot in area, it must be attached flat against the dwelling rather than freestanding or projecting, and its content is limited to the occupant's name and occupation, no logos, phone numbers, service lists or pricing.

Because the allowance is one sign per dwelling, a resident running more than one home occupation from the same address cannot post a separate sign for each. The rule sits inside § 120-139, the same section that limits home occupations to 25% of a dwelling's floor area and bars stock-in-trade sales, so a sign that also draws attention to on-site retail activity would raise compliance issues under those companion subsections as well. Any sign placed in violation, whether in R-1 or oversized or illuminated elsewhere, is treated as a zoning violation rather than a sign-code violation, since it is regulated directly in the home occupation section of Chapter 120.
