11 verified short-term rentals rules for Rialto, California, sourced directly from the municipal code and official government pages.
Verified from official government sources
Rialto Municipal Code Title 18 (Zoning) does not list short-term rentals or transient occupancy lodging as a permitted use in any residential zone, and no STR/vacation rental chapter has been adopted. Under the Title 18 permissive zoning rule, uses not expressly listed are not allowed, so operating an STR requires affirmative authorization that does not currently exist.
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.
Rialto imposes a 9% Transient Occupancy Tax (TOT) on stays of 30 consecutive days or less under Rialto Municipal Code Chapter 3.08 (effective January 18, 1991, per the State Controller's annual TOT report). The TOT applies to hotels, motels, and short-term residential rentals alike. Rialto has no STR-specific permit chapter — short-term hosts must obtain a standard Rental Income Property business license under Title 5 from the Business Licensing Division (909-820-2517) and remit TOT directly to the city. Airbnb does NOT have a TOT collection agreement with Rialto, so hosts must self-report.
Rialto does not impose STR-specific guest-parking minimums because the city has no STR ordinance. Hosts must rely on the general framework: Title 18 Zoning sets off-street parking minimums for the underlying dwelling (typically 2 covered spaces per single-family home in Rialto's R-1 zones), Title 10 Vehicles and Traffic governs on-street parking (including the 72-hour vehicle-storage rule under Cal. Veh. Code §22651(k)), and oversize/RV parking is restricted near the Rialto Municipal Airport (L67) AIA overlay and on residential streets per Title 10 posted-zone rules.
Rialto has no STR-specific guest-occupancy cap in its municipal code. Title 18 Zoning does not define 'short-term rental,' so no STR overlay (such as Palm Springs' '2 per bedroom + 2' rule) applies. Residential occupancy is governed by general standards: California Building Code (Title 24 CCR Part 2) minimum room area for sleeping rooms, and HUD's 'Keating Memo' two-persons-per-bedroom-plus-one fair-housing guideline. Rialto MC §3.08 simply defines a 'transient' as any occupant for 30 consecutive days or less, without setting a maximum-guest threshold.
Rialto does not impose a minimum liability-insurance requirement for short-term rental operators because the city has no STR-specific permit ordinance. STR-permit cities like Palm Springs and Santa Monica condition permits on $500K-$1M general liability coverage; Rialto's Rental Income Property business license under Title 5 does not. Hosts should still verify coverage because standard homeowner ISO HO-3 policies typically exclude 'business pursuits' losses, and Airbnb's $1M Host Liability Insurance / AirCover does not substitute for proper landlord/commercial policy.
Rialto does not impose an annual cap on the number of nights a host may rent short-term. Unlike Los Angeles (120 nights unhosted), San Francisco (90 nights unhosted), or Santa Monica (no whole-home STRs allowed), Rialto MC contains no night-cap provision. A host with a Rental Income Property business license under Title 5 and current TOT compliance under Chapter 3.08 (9% rate, transient = ≤30 consecutive days) can theoretically operate 365 nights/year. ADUs and JADUs remain capped at 30+ day minimum terms by Cal. Gov. Code §65852.2(a)(6).
Rialto has not established a short-term rental registry, certificate, or annual permit program in its municipal code. There is no STR-specific application, fee schedule, or inspection process in Title 5 or Title 18, so the only formal city registration available to an STR operator is a general business license under Chapter 5.04.
Rialto has no short-term rental ordinance and therefore no host-presence (on-site host) requirement, no off-site local contact rule, and no 24/7 emergency contact mandate specific to STRs. Because STRs are not a recognized land use in Title 18, the code provides no framework distinguishing hosted from unhosted operation.
Rialto's municipal code does not contain a short-term rental ordinance and therefore does not distinguish between primary-residence (hosted) STRs and non-owner-occupied (whole-home, investor) STRs. Because Title 18 zoning does not list STRs as a permitted use at all, there is no primary-residence exception that legalizes any class of operator.
County ordinances apply to unincorporated areas and may supplement Rialto city rules.
