San Bernardino County HOA Guide
Rialto HOA Guide: Local Rules for Boards and Owners
Rialto has about 106,500 residents by the Census Bureau’s July 2025 estimate, and about two in three homes are owner-occupied. The city has its own municipal code, so city ordinances apply to every association.
This guide collects the city rules a Rialto board runs into most often, and points you to the How2HOA guide that explains what to do about each one. Where we could not confirm a rule, we say so.
Local rules on this page were checked against the City of Rialto’s website and the Rialto Municipal Code on October 27, 2026. Several municipal code chapters and the city’s water ordinance PDFs would not open for us, and we found no city page about HOAs. This page covers only what we could confirm on official pages. Confirm the current rule before you act on it. Sources are listed at the bottom of the page.

HOAs in Rialto at a glance
We found no official Rialto page about HOAs or CC&Rs, and no public count of associations or typical dues, so we do not quote one. What the official sources do tell us:
Local rules
Rules that apply in Rialto
Three layers of rules apply to a Rialto association. State law comes first, mainly the Davis-Stirling Act. City ordinances apply to every property, whether or not it is in an HOA. Your governing documents can then be stricter than the city in most areas, and state law limits them in a few. The city does not enforce your CC&Rs, and your CC&Rs do not excuse anyone from a city rule.
Vehicles on private propertyVehicles, trailers and RVs may not park on front lawns or unpaved surfaces.
We could not confirm Rialto’s 72-hour street rule, overnight permits or RV rules for public streets. Chapter 10.28 of the municipal code would not open. We also found nothing on how the city handles parking on private streets. Call parking enforcement at (909) 820-2550 before you tell owners what the city will enforce.

Short-term rentalsWe could not confirm any Rialto short-term rental rule.
We found no official Rialto page on short-term rentals, and we do not rely on third-party sites for city rules. We cannot tell you whether the city allows, limits or bans them. Confirm with the city at (909) 820-2525 before you tell owners anything.
Whatever the city says, your association can set its own rules in its governing documents. A clear rental rule in your CC&Rs is the safest place to settle the question.
What to do about it: How to Handle Short-Term Rentals in Your Community walks through writing and enforcing a rental rule. For longer leases, see Renting Out Your Home in a Homeowners Association. For the California rules, see our guide to buying, selling and renting in a California HOA.
Two water providersThe city and West Valley Water District each serve some addresses.
Which provider serves an address is unconfirmed. The city says its water comes from the City of Rialto and Rialto Utility Authority, operated as Rialto Water Services, and that West Valley Water District serves some addresses. We did not find a map or list. Check your water bill, then confirm with the provider.
| Provider | What boards should know |
|---|---|
| Rialto Water Services | Call (909) 820-2546. The city site shows a Stage 2 Water Alert and links Ordinance No. 1560 on water conservation, but the PDFs would not open, so we could not confirm watering days or hours. City water rules are set by Resolution No. 7591. City rebates are for residential customers and, case by case, commercial customers. The page gives no dollar amounts and does not mention HOAs or multifamily sites. Turf replacement needs a pre-inspection, and rebates are first come, first served. Utilities Division: (909) 820-2525, extension 2062. |
| West Valley Water District | Call (909) 875-1804 for rules and rebates in its service area. |
A state law passed in 2023 (AB 1572) restricts the use of drinking water on nonfunctional turf in HOA common areas. We are not stating a start date for it here. Confirm the date that applies to you with your water provider.
What to do about it: put the turf conversion in your numbers with Planning Your HOA Budget and Understanding HOA Reserve Studies, then compare landscape bids with the Vendor Comparison Worksheet. For the California rules behind these projects, see California HOA maintenance and repair responsibilities and California HOA reserves.
Weed abatementNotices go out April 1 and September 1. Work is due May 15 and October 15.
Rialto Fire Prevention runs weed abatement twice a year:
| Cycle | Owners notified | Work due |
|---|---|---|
| Spring | April 1 | May 15 |
| Fall | September 1 | October 15 |
- Weeds or dry grass over 4 inches are a violation.
- Tree branches must be trimmed to 8 feet off the ground.
- Owners are responsible for easements around their parcel.
- If work is not done, a city contractor does it and bills the owner. The cost may become a lien or a direct charge on the tax roll.
Call (909) 820-2525 with questions. Board members should walk the common areas and slopes before each notice date.
What to do about it: How to Minimize Homeowners Association Liability, and Managing Outside Vendors for Your HOA for scheduling the landscaper.
Fire hazard severity zonesThe city says Rialto properties fall into Moderate, High or Very High zones.
The State Fire Marshal issued recommended 2025 maps for Local Responsibility Areas on March 24, 2025, and the city page says the city must adopt them by ordinance within 120 days. The city says it is not proposing increases. We did not confirm the final adoption ordinance or its effective date.
The city says home hardening and the wildland-urban interface building code apply in High and Very High zones, and that Very High zones require 100 feet of defensible space. Confirm the rule for your property with Fire Prevention at (909) 820-2525 before you change a slope contract.

Common code violationsOvergrown landscaping, trash in public view and unpermitted construction top the city’s list.
The city’s common violations list includes overgrown landscaping, trash and debris in public view, unpermitted construction and inoperable vehicles in public view. Report at (909) 820-8070 or CodeCompliance@RialtoCA.gov. The Community Compliance Division office is at 128 N. Willow Ave. For unpermitted construction, call the Building Division at (909) 820-2505.
We could not confirm Rialto’s noise limits, construction hours or tree ordinance. The municipal code chapter on noise (9.50) would not open. Ask Community Compliance before you set work hours in a vendor contract.
What to do about it: How to Enforce HOA Rules in Your Homeowners Association covers getting owners and tenants to follow a new rule.
Is this a lot for a volunteer board to track?
City rules, state law and your own documents all change, and someone has to keep up. If your Rialto board is deciding between managing itself and hiring help, start with Self-Managed vs. Professional HOA Management, or tell us about your community and we will send you options from affiliated management companies.
