Rialto's Short-Term Rentals: The Rules That Matter

Every city handles short-term rentals a little differently. In Rialto, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Short-Term Rental Permits

Rialto has no short-term-rental-specific permit ordinance, but anyone renting rooms or dwellings on a transient basis must obtain a City business license under the Rental Income Property classification (Rialto Municipal Code Chapter 5.70) and register with the tax administrator for a Transient Occupancy Registration Certificate under RMC 3.08.060.

Key details: STR-specific permit: None - no dedicated STR ordinance. Business license: Required - RMC Ch. 5.70 (Rental Income Property). TOT registration: Required within 30 days - RMC 3.08.060. New application admin fee: $47.30 + $4.00 state fee. Renewal admin fee: $32.40 + $4.00 state fee.

Transacting rental business without the required business license is unlawful under RMC 5.70.020 and is punishable as a misdemeanor under RMC 1.16.010 (up to $1,000 fine and/or six months in jail), or as an infraction at the prosecutor's election ($100 first offense, $200 second, $500 each additional within two years). Failure to register for the TOT certificate is a misdemeanor under RMC 3.08.140. Administrative citations and daily fines may also be issued under RMC Chapter 1.10.

Taxes & Fees

Rialto charges a 9 percent transient occupancy tax on any stay of 30 consecutive days or less, including short-term rentals booked through a hotel, motel or similar structure. Operators collect it from guests and remit it quarterly to the city's tax administrator.

Key details: Tax rate: 9 percent of rent charged. Taxable stay length: 30 consecutive days or less. Registration deadline: Within 30 days of starting business. Filing frequency: Quarterly, due end of following month. Late penalty: 10 percent, plus 10 percent more after 30 days.

Failing to remit on time adds a 10 percent penalty, rising to 20 percent combined after 30 days, and 25 percent more if the tax administrator finds fraud, on top of 0.5 percent monthly interest. Operators who fail to collect or report face a city-estimated assessment, notice by mail, and a 10-day window to request a hearing before the amount becomes final and payable.

Occupancy Limits

No Rialto-specific ordinance directly addresses short-term rental occupancy limits; California state default applies. General habitability and occupancy standards flow from the State Housing Law (Health and Safety Code Sec. 17922), which adopts Uniform Housing Code requirements.

Key details: Local STR occupancy cap: None adopted. Transient threshold: 30 consecutive days or less - RMC 3.08.020(D). State default: Uniform Housing Code standards via HSC Sec. 17922. Common UHC guideline: About 2 persons per bedroom plus 1. Nuisance backstop: RMC Ch. 18.72 property maintenance rules.

Because there is no local STR occupancy ordinance, the City cannot cite a host simply for guest count. Overcrowding that violates state habitability standards adopted under Health and Safety Code Sec. 17922, or conditions creating a nuisance under RMC Chapter 18.72 (Property Maintenance - Nuisances), can be enforced through code enforcement action, administrative citations under RMC Chapter 1.10, or misdemeanor/infraction prosecution under RMC 1.16.010.

The Bottom Line

Rialto's short-term rentals rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Rialto is broadly strict or permissive.
