San Antonio, TX Home Business: Customer Traffic Restrictions (2026)

Sec. 35-378(b) of the Unified Development Code sets the traffic ceiling for every home-based business in San Antonio's residential zoning districts. The rule is a flat prohibition rather than a numeric visitor cap: no home occupation may generate on-street parking, substantially increase traffic in the area, or violate the city's noise ordinance. Subsection (a)(1) reinforces the limit by requiring that a home occupation not alter the premises' residential character through increased traffic, among other listed impacts like signs, odors, sounds, or vibrations, and it expressly cross-references the city's noise, nuisance, and short-term rental regulations as also applicable.

Subsection (a)(4) further ties customer volume to the dwelling's lawful occupancy: the number of employees at a home business, combined with residents and customers on site, cannot exceed the permitted occupancy of the dwelling unit. Because there is no separate customer-count permit, code enforcement and Development Services evaluate traffic and parking complaints case by case against these standards, typically triggered by neighbor complaints about cars parked on the street or a steady stream of client visits. A home occupation found to substantially increase area traffic or push parking onto the street can lose its by-right status and be ordered to cease, independent of any separate finding on signage, noise, or use type.
