San Bernardino County
Rialto has no STR-tailored quiet-hours or 'one-strike' permit rule because the city lacks an STR ordinance. All noise complaints — including those at vacation rentals — are enforced under Rialto MC Chapter 9.50 (Noise Control), which prohibits loud, unreasonable, or 'plainly audible' sound (the rhythmic bass component of music alone is sufficient evidence). Chapter 9.50 is administered jointly by Rialto Police and the Department of Development Services Code Enforcement Division. Construction noise has seasonal time windows (Oct 1–Apr 30 vs May 1–Sep 30); residential noise complaints follow the general nuisance standard.
