Summary

A Tucson home occupation may display just one sign, and it can't exceed one square foot, a fraction of the standard commercial sign allowance, under UDC § 4.9.7.E.10, which also folds in the city's general sign code for placement and construction.

10. No more than one sign shall be visible from the exterior of the property used as a home occupation. The sign shall not exceed one square foot in size. Signs shall also conform to Chapter 3 of the Tucson Code.

Full Breakdown

10 states plainly: 'No more than one sign shall be visible from the exterior of the property used as a home occupation. 10), meaning the citywide sign regulations govern construction, illumination, and placement details beyond the size cap itself, a home occupation sign can't be a lit, freestanding, or pole-mounted display; at one square foot it functions as little more than a small wall or window placard. 9 treats unauthorized exterior alteration, including oversized signage, as incompatible with the home occupation's residential character requirement.

Violations & Fines

A sign larger than one square foot, or a second sign, is both a Chapter 3 sign-code violation and a breach of the home-occupation standards; PDSD or code enforcement can order removal and, for repeat or unresolved cases, revoke the underlying home-occupation approval, exposing the operator to civil-infraction penalties.

Frequently Asked Questions

How big can my home business sign be in Tucson?
One square foot, maximum, and only one sign. UDC § 4.9.7.E.10 sets both limits explicitly, far smaller than the allowances for a standalone commercial sign under Chapter 3.
Can I put up a lit or freestanding sign for my home business?
No. Beyond the one-square-foot size cap, the sign must conform to Chapter 3 of the Tucson Code, and § 4.9.7.E.9 bars the home occupation from altering the residence's exterior appearance through lighting or other means.
What happens if my home business sign is too big?
Code enforcement or PDSD can order the sign removed, and because § 4.9.7.E.9 ties exterior alteration to the compatibility standard for the whole home occupation, a persistent oversized sign can put the underlying zoning approval itself at risk.
