Fence Companyin Rialto, CA
Every fence in Rialto needs a permit, because the City deleted the state exemption for fences up to 7 feet. Side and rear fences top out at 6 feet and a solid front yard fence at 3.5 feet. Block walls follow a City standard, retaining walls and wrought iron fences take separate permits, and pools need a 5 foot barrier.
Rialto's fences stand on very different ground. The townsite dates to 1887, Foothill Boulevard became U.S. Route 66 in 1913 and a 1920s fire destroyed many downtown buildings, but ACS 2024 one-year estimates count 27,511 housing units, 72.3 percent of them single-family detached and 35.0 percent built in the 1980s. About 28.9 percent of occupied homes are rented, so the person ordering a fence is often not the person who owns the lot.
On a fence job, MDG Builders (CSLB #1040337) reads the limits for the yard before pricing it, files the permit and keeps the crews in order, with a licensed C-13 fencing subcontractor setting posts and rails and a masonry-licensed subcontractor handling any block. The fencing page lists our sourced prices, the Rialto overview covers every trade here, and the guides for Fontana and Ontario show how two neighbors set fence limits. Permits come from the Building & Safety Division, and zoning questions go to the Planning Division. Municode, the City's code host, returned an HTTP 403 challenge to our tools, so code text below comes from the third-party GoCodebook mirror and should be confirmed with the City.
What Rialto's Municipal Code 15.08, zoning exceptions and block wall handouts say about fences
Where fencing permits come from in Rialto: City of Rialto Community Development Department, Building & Safety Division.
- Fences need a permit in Rialto even when they are 7 feet or lower: Municipal Code 15.08.030 and 15.08.040 delete CBC and CRC 105.2 exception 2 (the usual exemption for fences up to 7 feet) because of local seismic activity, high winds and the need for noncombustible materials against embers. (GoCodebook mirror)
- Fence height under Municipal Code 18.56.030: 6 feet in side and rear yards, a solid fence or wall of no more than 3.5 feet in the front yard setback (a hedge, chain link, wrought iron or block pilasters can reach 6 feet there, with pilasters no closer than 6 feet on center), and on corner lots 6 feet and at least 12 feet from the curb face. Street-side fences over 3.5 feet may not extend forward of the nearest part of the house except approved security fences, and barbed or razor wire is banned in residential zones. (GoCodebook mirror)
- Block walls: the City's standard freestanding block wall handout requires 8 inch slumpblock or 6 inch precision block (6 inch slump and 4 inch precision are not permitted), footings 5 feet to daylight next to slopes, block color and finish that match the neighborhood, no grout before inspection, and says the standard wall may not retain earth. Retaining walls and freestanding walls take their own permit.
- A wall on a property line needs a notarized Common Wall Agreement signed by every affected neighbor (each with their own form), or a Foundation Line and Grade certification from a licensed engineer or surveyor; an aerial map with distances to the property line must be attached.
- Pool fences: Municipal Code 15.36.030 requires a fence or solid structure at least 5 feet high around any pool or spa (including any water over 12 inches deep) with no opening wider than 4 inches and wire mesh limited to 2 inches, and the City's barrier handout adds self-closing, self-latching outward-opening gates and door alarms. CRC Appendix CI (15.08.040) makes a pool without a compliant fence meet it whenever the property gets a pool renovation, ADU, new dwelling or addition. (GoCodebook mirror)
- Along Foothill Boulevard (old Route 66), Municipal Code 18.62 bans new buildings, structures or signs within 55 feet of the centerline in the planned right of way; legal nonconforming structures were required to be removed by June 30, 2016, with no outward additions allowed on any that remain.

Do I need a permit to build a fence in Rialto, even one under 7 feet?
Yes. Municipal Code 15.08.030 and 15.08.040 delete CBC and CRC 105.2 exception 2, the usual state exemption for fences up to 7 feet, citing local seismic activity, high winds and the need for noncombustible materials against embers. That makes Rialto stricter than the model code, and the rule reaches a plain wood fence as much as a block wall.
The City's Residential Plan Submittal Guideline says most projects need a plan, at minimum a site plan on 11 by 17 paper showing the work, the owner, the APN and the contractor license, and a city-standard block wall can be approved over the counter by a permit technician with a site plan and Planning approval. Retaining walls, freestanding walls, monument and screen walls and wrought iron fences each take their own permit, and a fire access gate takes a separate fire permit. Applications go through the Online Permitting Center, and the contractor needs a City business license under Municipal Code 5.56. The Building & Safety page lists Monday through Friday hours and the Community Development page Monday through Thursday, so call 909-820-2505 before visiting.
Ask the fence contractor to confirm in writing that the proposal includes the permit and the site plan.
How tall can a fence be in my front, side and rear yard in Rialto?
Municipal Code 18.56.030 sets 6 feet for fences in side and rear yards. In the front yard setback a solid fence or wall may be no more than 3.5 feet, while a hedge, chain link, wrought iron or block pilasters can reach 6 feet, with the pilasters no closer than 6 feet on center. On a corner lot the limit is 6 feet, and the fence must stay at least 12 feet from the curb face.
A street-side fence over 3.5 feet may not extend forward of the nearest part of the house, except approved security fences, and barbed or razor wire is banned in residential zones. We found no provision that allows 7 feet in a residential yard. Single-family R-1 zoning sets an 8,400 square foot minimum lot, an 80 foot width and interior side yards of 10 percent of the lot width, between 3 and 5 feet, so measure the setback before choosing a height. Rialto has other R-1 variants with their own chapters that we did not read.
Mark the property line and the setback on a sketch before the contractor picks a height.
What does Rialto require for a block wall, and what is the retaining wall rule?
The City's handout for a standard freestanding block wall requires 8 inch slumpblock or 6 inch precision block, and says 6 inch slump and 4 inch precision block are not permitted. Footings must sit 5 feet to daylight beside a slope, the block color and finish must match the neighborhood, nothing may be grouted before the inspection, and the standard wall may not retain earth.
A wall that holds back soil is a retaining wall and takes its own permit. The City's standard retaining wall handout shows heights up to 6 feet with #4 horizontal rebar at 24 inches on center and footing and key sizes by wall height, and taller or nonstandard walls need engineered plans. In California a fence contractor holds CSLB class C-13, which excludes masonry walls, while block walls belong to masonry class C-29, so a proposal that includes both should name two licensed trades.
Ask for the wall's footing depth, block size and rebar spacing in writing before you sign.
Who pays for a fence on the property line, and what is a Common Wall Agreement?
A wall built on a property line needs either a notarized Common Wall Agreement signed by every affected neighbor, each on their own form, or a Foundation Line and Grade certification from a licensed engineer or surveyor. An aerial map showing distances to the property line must be attached. The agreement route depends on every neighbor signing, so start that conversation before the quote, while the survey route does not.
California Civil Code 841 presumes that adjoining owners share the cost of a boundary fence equally and asks the owner who plans the work to give 30 days' written notice, though the presumption can be rebutted. The statute decides who pays, not whether the City issues the permit. A surveyor's stakes also settle where the line really runs, which matters on older lots where an existing fence may sit off the line.
Send neighbors written notice early and keep a copy with the permit file.
What fence does a Rialto pool or spa need?
Municipal Code 15.36.030 requires a fence or solid structure at least 5 feet high around any pool or spa, including any water more than 12 inches deep, with no opening wider than 4 inches and wire mesh limited to 2 inches. The City's barrier handout adds self-closing, self-latching gates that open outward, plus door alarms.
A pool without a compliant fence has to meet the rule whenever the property gets a pool renovation, an ADU, a new dwelling or an addition, under CRC Appendix CI as adopted in 15.08.040. State law adds a second layer: Health and Safety Code 115922 asks for at least two of seven drowning-prevention features when a permit issues for a new or remodeled pool. The City's pool fence handout carries a 2015 revision date, so ask Building which edition its inspectors use.
Have the opening size and the gate latch checked against the City's barrier handout before the fence is stained or painted.
Do gates, Foothill Boulevard or the specific plans change what I can build in Rialto?
They can. Along Foothill Boulevard, the old Route 66, Municipal Code 18.62 bars new buildings, structures or signs within 55 feet of the centerline in the planned right of way, and nonconforming structures there were to be removed by June 30, 2016, with no outward additions to any that remain. The City also lists nine specific plans, Agua Mansa, Elm Park, Foothill Central, Gateway, Lytle Creek Ranch, Northwest Rialto, Pepper Avenue, Renaissance and Rialto Airport, that can override base zoning for parcels inside them.
On a parcel with the D architectural design overlay, Municipal Code 18.46.020 sends plans for any building, structure, sign or landscaping to the Planning Commission before construction. Whether a plain fence counts as a structure there is a question for Planning at 909-820-2535, and we cannot promise an answer. A driveway gate on a fire access route takes a separate fire permit, and material or a dumpster placed in the public right of way needs an Engineering permit.
Ask Planning for the parcel's zoning and overlays before the fence layout is drawn.
How much does fence installation cost in Rialto, and who should I hire?
No Rialto price survey turned up, so these are Los Angeles figures. Angi's Los Angeles page, updated August 4, 2026, shows an average of $3,051 inside a $1,734 to $4,422 range, wood at $1,600 to $2,500 and vinyl at $1,850 to $3,400 for a standard job, while its national page lists gates at $150 to $2,000 and old fence removal at $3 to $5 a foot. Federal data put Los Angeles-area fence erectors at $28.00 an hour in May 2025. Block walls have no independent per-foot source that we found, so we print no block price. Our planning ranges are $25 to $55 a foot for wood or vinyl, $12 to $30 for chain link and $35 to $85 for aluminum or ornamental iron.
Fence work calls for a C-13 contractor, and a Rialto permit needs the state license and the City business license on file. Business and Professions Code 7159 requires a signed written contract and caps a down payment at $1,000 or 10 percent, whichever is less. Before hiring, run the contractor through our license guide, and see how general contractors use subcontractors for who builds what. The City bases building permit fees on a 1997 Uniform Building Code valuation table whose layout is garbled in the PDF, so we print no fence fee.

Where these Rialto fence figures come from
Prices for each fence material, with their sources and dates, sit in the table on the fencing page, along with the figures that disagree. A new fence often arrives alongside other exterior work, and the Rialto rules for it are on the roofing page, the painting page and the kitchen remodeling page. To see a Los Angeles County fence rulebook beside this one, read the guide for Pasadena.
| What it covers | Typical range |
|---|---|
| Wood or vinyl privacy fence, 6 feet | $25 to $55 per linear foot |
| Chain-link | $12 to $30 per linear foot |
| Aluminum or ornamental iron | $35 to $85 per linear foot |
| Typical 100-foot backyard run | $2,500 to $5,500 total |
| Block walls, horizontal slat fences, gates and openers, hillside lots | Set by the written proposal |
Rialto fence questions, answered
Do I need a permit to build a fence in Rialto?
Yes, for every fence. Rialto's Municipal Code 15.08 deletes the state exemption for fences up to 7 feet, so even a low wood fence needs a permit, usually with a site plan showing the location, owner, APN and contractor license. Applications go through the Online Permitting Center. Call Building and Safety at 909-820-2505 to confirm what your fence needs.
Can I put up a 7 foot fence in Rialto?
We found no provision for it in a residential yard. Municipal Code 18.56.030 sets 6 feet in side and rear yards and 3.5 feet for a solid front fence, and every fence needs a permit under 15.08, so the usual state 7 foot exemption does not apply. Ask Planning at 909-820-2535 before drawing anything taller than 6 feet.
How tall can a front yard fence be in Rialto?
A solid front yard fence or wall can be no more than 3.5 feet. A hedge, chain link, wrought iron fence or block pilasters can reach 6 feet in the front yard setback, with pilasters at least 6 feet apart on center. On a corner lot the limit is 6 feet, and the fence must stay at least 12 feet from the curb face.
Do I need a permit for a cinder block wall in Rialto?
Yes. Every fence or wall needs a permit, and freestanding walls sit on the City's separate permit list. A city-standard block wall built to the handout can be approved over the counter with a site plan and Planning approval. Standard walls use 8 inch slumpblock or 6 inch precision block, and a wall that retains soil needs its own retaining wall permit.
How much does it cost to have 100 feet of fence installed?
At our planning range of $25 to $55 a foot for wood or vinyl, 100 feet runs about $2,500 to $5,500, while Angi's Los Angeles table shows 100 feet at $2,100 to $2,350. Block, steel, gates, old fence removal and the permit are extra. These are Los Angeles figures, so a written Rialto proposal is the real price.
What happens if I build a fence without a permit in Rialto?
It becomes an unpermitted structure. Municipal Code 15.08 amends CBC 105.1.3 to make it unlawful to own, use or occupy anything built without a required permit, and CBC 114.5 requires a special investigation before a permit is issued for work already started. We did not read a penalty schedule, so we print no dollar amount.
What are the pool fence requirements in Rialto?
A pool or spa needs a fence or solid structure at least 5 feet high under Municipal Code 15.36.030, with no opening wider than 4 inches and wire mesh limited to 2 inches. The rule covers any water over 12 inches deep, and the City's barrier handout adds self-closing, self-latching gates that open outward and door alarms.
Who pays for a shared fence in Rialto?
California Civil Code 841 presumes neighbors share the cost of a boundary fence equally, after 30 days' written notice, though the presumption can be rebutted. Rialto separately requires a notarized Common Wall Agreement signed by each affected neighbor, or a Foundation Line and Grade certification from a licensed engineer or surveyor, for a wall on a property line.
What is the maximum height of a retaining wall without a permit in Rialto?
We found no height that avoids a permit. The state model code exempts retaining walls up to 4 feet, but Rialto's separate permit list names retaining walls without a height exception, and the City's standard handout shows walls up to 6 feet. Taller or nonstandard walls need engineered plans, so ask Building before you dig.
What is the difference between a fence company and a masonry contractor?
A fence company holds CSLB class C-13, which excludes masonry walls, while block walls belong to masonry class C-29, and a job with a wood fence and a block wall can need both. MDG Builders, CSLB #1040337, manages the permit and brings in licensed fencing and masonry subcontractors, whose license numbers you can ask to see.
