Union City has no STR-specific noise ordinance. Short-term rental guests are subject to the citywide noise and nuisance rules, and zoning requires that residential uses not create noise impacts on adjacent residents.
No dedicated short-term rental quiet-hours ordinance has been adopted. Noise from rentals is governed by the city's general noise and nuisance provisions, enforced by police and code enforcement. Within the residential zoning code, UCMC Section 18.32.020 requires that home occupations create no noise audible beyond the site boundaries and that accessory dwelling units be designed so as not to create noise impacts on adjacent residents and yards. These standards reflect the city's general expectation that residential uses, including rentals, avoid disturbing neighbors. Specific decibel limits or STR quiet-hour windows advertised by platforms are unverified and not found in the Municipal Code as STR-specific rules.
Excessive noise or disturbances are enforceable as nuisance and noise violations through police response and code enforcement, with possible citations and abatement.
