Fence Companyin Montclair, CA
Assume any new fence or masonry wall in Montclair needs a building permit: MMC 10.24.010 requires one for every fence, and the City's block wall page says masonry walls of 24 inches or more do. Fences top out at 6 feet in side and rear yards and 48 inches in a front yard, and new chain link is banned there.
Montclair's fence lines follow a grid cut from citrus groves. John C. Reeder bought the five-acre Reeder Ranch on Holt Boulevard in 1900 and grew it past 50 acres, and in 1907 Los Angeles developer Emil Firth paid a reported $250,000 for a 1,000 acre tract between Holt and Phillips boulevards that he named Monte Vista, per the City's General Plan and Housing Element. After World War II the groves became tract subdivisions. ACS 2020-2024 counts 6,141 single-family detached homes, 56.0 percent of 10,974 units, with a median year built of 1969, so one fence code covers lots drawn in the 1950s and later infill.
On a fence job, MDG Builders (CSLB #1040337) is the general contractor: we walk the lot, file the permit and schedule a licensed fencing subcontractor, or a masonry subcontractor when the wall is block. Our fencing page holds the sourced prices, and the Montclair overview lists every trade we manage here. For a comparison across the county line, the Upland and Chino guides cover San Bernardino County neighbors, and Claremont follows Los Angeles County rules. Permits come from the City's Building Division. Municode, the host the City links for its code, returned HTTP 403 to our researcher and was not opened, so every code rule below was read in GoCodebook's third-party mirror, text as of October 4, 2026. Treat each as a draft until the counter confirms it, and note that the City's block wall handouts date from 2010.
What Montclair's fence chapter, zoning heights and block wall handouts say
Where fencing permits come from in Montclair: City of Montclair Community Development Department, Building Division.
- Permit: MMC 10.24.010 says no person may erect or install any fence or block or masonry wall without first getting a permit from the Building Official (fee per the Development Review Fee Schedule), and MMC 10.08.020 and 10.04.020 delete item 2 of the model code's list of work exempt from permit (the item's text is not reproduced in the City's code). The Block Wall page separately says all masonry walls 24 inches or more in height need a building permit; read together, assume any new fence needs a permit and confirm small garden walls at the counter. (read in GoCodebook's third-party code mirror, text as of 2026-10-04)
- Heights (MMC 11.38.050.N): up to 6 feet on rear and side lot lines and behind the front setback; no more than 48 inches in a required front yard or the street side yard of a corner lot, except masonry pilasters up to 54 inches (16 by 16 inches, at least 8 feet apart) with 'open' fencing that passes at least 75 percent light and air; up to 8 feet by administrative adjustment where security, privacy or a grade change justify it; and no new chain-link in front or street-side setbacks (repairs under 50 percent of the existing fence are allowed). (read in GoCodebook's third-party code mirror, text as of 2026-10-04)
- Corner cutoff: fences and walls are prohibited inside the corner visibility triangle (a 45 degree line through points 30 feet from the corner on each lot line, and 10 feet from each side of a driveway or alley mouth), and landscaping there may not exceed 30 inches (MMC 11.38.050.M). The administrative-adjustment chapter (MMC 11.76.020.A) refers to 42 inches on a reversed corner lot while 11.38.050 says 48 inches, a conflict worth raising with Planning. (read in GoCodebook's third-party code mirror, text as of 2026-10-04)
- Block wall submittal: the permit application needs a plot plan showing owner and APN, scale and north arrow, property lines, abutting streets, existing and proposed structures, distance from the wall to structures and lot lines, and the type, length and height of every wall. The Building Division offers pre-engineered residential masonry wall plans; anything else needs an engineered design.
- City standard block wall handouts are dated January 1, 2010: the free-standing wall sheet assumes 85 mph Exposure C, Seismic Design Category E, 1,500 psf allowable soil bearing and a footing sized by wall height.
- The combination retaining/block wall handout (also 2010) shows a retained portion of 2 feet under a wall of up to 6 feet total, with solid-grouted cells in the retaining portion. Retaining walls of 3 feet or less (footing bottom to wall top) are exempt from permit unless they carry a surcharge or impound liquids (MMC 10.08.020). (read in GoCodebook's third-party code mirror, text as of 2026-10-04)
- Pool barriers: MMC 10.48.020 requires a fence or solid structure at least 5 feet high around every swimming pool (holding water over 12 inches) with no openings over 4 inches, and self-closing, self-latching gates. (read in GoCodebook's third-party code mirror, text as of 2026-10-04)
- Pools, spas and hot tubs are not allowed in front or street-side yards of single-family lots (MMC 11.19.060, major accessory structure setbacks). (read in GoCodebook's third-party code mirror, text as of 2026-10-04)

What do Montclair's 7,500 square foot lots mean for a fence line and a shared wall?
Single-family tracts are zoned R-1, where the code sets 7,500 square feet per lot, 60 feet of frontage (65 on corners) and 100 feet of depth. Side yards are 5 feet on one side and 12 on the other where there is no alley, and a small-lot overlay mapped in some tracts allows 4,500 square foot lots 50 feet wide. Those numbers decide how close a wall can sit to the house, and the City's zoning lookup gives each parcel's designation by address. The property line, not the existing fence, is the starting point, so a survey beats a guess when a wall has moved over the decades.
A fence on the line is shared by law. California Civil Code 841 presumes neighbors split the cost of a boundary fence that benefits both, requires 30 days' written notice before one neighbor incurs costs, and the presumption can be rebutted. Read the official text and send the notice in writing before a quote is signed. The price table on the fencing page shows what a shared run costs before it is divided.
Photograph the existing fence and send the neighbor notice before demolition.
How tall can a fence be in a Montclair front yard, side yard or backyard?
MMC 11.38.050.N allows fences up to 6 feet along rear and side lot lines and behind the front setback. In a required front yard, or the street side yard of a corner lot, the limit is 48 inches. The R-1 front yard is 25 feet deep, though no deeper than the average of the two neighbors, so the 48 inch zone can reach a long way back on some lots.
There is a bonus for open design. Masonry pilasters may rise to 54 inches, if they are 16 by 16 inches and at least 8 feet apart, when the fencing between them is open and passes at least 75 percent of light and air. A taller fence can be requested through an administrative adjustment under MMC 11.76, which lets the Community Development Director approve up to 8 feet where security, privacy or a grade change justifies it. The Director reviews within 10 working days of a complete application and decides within 40 days, and an appeal goes to the Planning Commission within 10 days.
Measure from the property line to the setback line before choosing a style.
Why does Montclair require a permit for every fence, and what happens without one?
MMC 10.24.010 says no one may erect or install any fence or block or masonry wall without first getting a permit from the Building Official. The amended building code also deletes item 2 from the model code's list of work exempt from permit, and the City's code does not reproduce that item's text, so we cannot say what it covered. The Block Wall page separately says masonry walls of 24 inches or more need a permit. Read together, assume a permit for any new fence and confirm small garden walls at the counter. The fee comes from the Development Review Fee Schedule, whose 2022 table did not extract, so we quote no amount.
Work without a permit draws a special investigation and an investigation fee on top of the permit fee. For a fourth offense by the same person or entity, the fee is ten times the scheduled amount. Counter hours are Monday through Thursday, 7:00 to 9:00 a.m. and 4:00 to 5:30 p.m., and City Hall is closed on Fridays. Historic review reaches only designated landmarks under MMC 11.56, and the one we found named is the Reeder Ranch at 4405 Holt Boulevard.
Ask the counter to put the permit answer for your fence in writing.
What does a Montclair block wall or retaining wall need, and are the City's plans current?
A masonry wall permit application needs a plot plan showing the owner and parcel number, scale and north arrow, property lines, abutting streets, existing and proposed structures, the distance from the wall to each structure and lot line, and the type, length and height of every wall. The Building Division offers pre-engineered residential masonry wall plans, and anything else needs an engineered design. Masonry walls fall under CSLB class C-29, since the C-13 fencing class excludes masonry.
Check the vintage of the drawings. The City's free-standing wall sheet and its combination retaining wall sheet are dated January 1, 2010, and the free-standing sheet assumes 85 mph wind in Exposure C, Seismic Design Category E and 1,500 psf soil bearing. The City's current design criteria list 96 mph in Exposure B. The combination sheet shows a retained portion of 2 feet under a wall of up to 6 feet in total, with solid-grouted cells below. Retaining walls up to 3 feet, measured from the bottom of the footing to the top, are exempt unless they carry a surcharge or hold liquids, so a retaining wall under a fence can change the whole answer.
Ask whether the 2010 sheet still applies before the mason orders block.
Is chain link allowed in Montclair, and what changes at a corner lot or driveway?
New chain link is not allowed in front or street-side setbacks, though repairs of less than 50 percent of an existing fence are. Electrified security fences are allowed only on industrial and commercial property, as monitored pulsed systems, by permit from the Community Development Director.
Corners have their own geometry. Fences and walls are prohibited inside the corner visibility triangle, formed by a 45 degree line through points 30 feet from the corner on each lot line and 10 feet from each side of a driveway or alley mouth, and landscaping there cannot exceed 30 inches. The administrative adjustment chapter mentions 42 inches on a reversed corner lot while MMC 11.38.050 says 48 inches, a conflict worth raising with Planning before a street-side fence is drawn.
What do Montclair's pool barrier rules mean for a fence or gate replacement?
MMC 10.48.020 requires a fence or solid structure at least 5 feet high around every swimming pool that holds water more than 12 inches deep, with no openings over 4 inches and self-closing, self-latching gates. A replacement fence along a pool yard must keep those numbers. Pools, spas and hot tubs are not allowed in front or street-side yards of single-family lots under MMC 11.19.060, so the barrier question is always a backyard one.
State law adds to it. Health and Safety Code 115922 asks for at least two drowning-prevention features when a permit issues for a new or remodeled pool, and the enclosure must meet section 115923, whose text we did not read. Since a fence permit is already required here, ask Building to check the barrier at the same visit. Montclair's drainage rules matter too: the City's stormwater page asks crews to call (909) 625-9447 before discharging pool water to the street.
How much does fence installation cost in Montclair, and who should I hire?
We found no Montclair price survey, so the numbers come from Los Angeles and national sources. Angi's Los Angeles guide, updated August 4, 2026, shows an average of $3,051 and a $15 to $60 per foot range, with a 100 foot run at $2,100 to $2,350. HomeGuide shows $20 to $60 a foot, Thumbtack $23 to $57 nationally, and the federal wage survey puts fence erectors in the Los Angeles-Long Beach-Anaheim area at a mean of $28.00 an hour in May 2025. Our planning ranges, installed at 6 feet: wood or vinyl privacy $25 to $55 a foot, chain link $12 to $30, aluminum or ornamental iron $35 to $85, so a 100 foot backyard run lands near $2,500 to $5,500. Block walls get no per-foot figure here, because no independent Los Angeles source for them turned up.
Fencing is CSLB class C-13. Business and Professions Code 7159 requires a signed written contract, caps the down payment at $1,000 or 10 percent, whichever is less, and ties payments to finished work. Our license guide shows the lookup, and the subcontractor guide explains how the general contractor and the fence crew divide the job.

Where these Montclair fence figures come from
Every fence price, with its source and date, is in the table on the fencing page. A new fence often follows a roof or paint job, and Montclair's rules for those are on the roofing page and the painting page. For a rulebook from a county that treats the same work differently, see the fencing guide for Glendale.
| 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 |
Montclair fence questions, answered
Do I need a permit to build a fence in Montclair, California?
Assume yes. MMC 10.24.010 requires a permit from the Building Official for any fence or block wall, and the City's block wall page says masonry walls of 24 inches or more need one. Fees follow the City's fee schedule. Call (909) 625-9477 and ask for the answer in writing before work begins.
How tall can my front fence be in California, and what does Montclair allow?
Montclair allows no more than 48 inches in a required front yard or the street side yard of a corner lot. Masonry pilasters may reach 54 inches with open fencing between them that passes at least 75 percent of light and air. Measure against Montclair's code and not a statewide figure.
How tall can a fence be in the backyard in Montclair?
Up to 6 feet along rear and side lot lines and behind the front setback. A taller fence, up to 8 feet, can be requested through an administrative adjustment where security, privacy or a grade change justifies it. The Community Development Director reviews within 10 working days and decides within 40 days of a complete application.
Is chain link allowed in Montclair?
Not as a new fence in front or street-side setbacks. Repairs of less than 50 percent of an existing chain-link fence are allowed there and we found no chain-link ban behind the setbacks. Electrified fences are limited to industrial and commercial property. Ask the counter about your lot before choosing a material.
Does my neighbor have to pay for half the fence in California?
Usually the cost of a boundary fence that benefits both properties is presumed shared equally under Civil Code 841, but the presumption can be rebutted. You must give the neighbor 30 days' written notice before incurring costs. The official text spells out what a neighbor can contest.
Do you need a permit to build a block wall in California, and what about Montclair?
In Montclair, yes. The City says masonry walls of 24 inches or more need a building permit and requires a plot plan, with pre-engineered plans available for residential masonry walls. Retaining walls of 3 feet or less, measured from footing bottom to wall top, are exempt unless they carry a surcharge or hold liquids.
What are the pool fence requirements in California, and in Montclair?
Montclair requires a fence or solid structure at least 5 feet high around any pool deeper than 12 inches, with no openings over 4 inches and self-closing, self-latching gates. State law adds drowning-prevention features for new or remodeled pools under Health and Safety Code 115922. Pools may not sit in front or street-side yards.
How much does fence installation cost in California and in Montclair?
Montclair has no published survey. Angi's Los Angeles guide gives $15 to $60 a foot, and our planning range is $25 to $55 for wood or vinyl at 6 feet, so a 100 foot run is roughly $2,500 to $5,500. Gates, old fence removal, slopes and permits add to it. A written quote should list each item.
What happens if I build a fence without a permit in Montclair?
The Building Official can open a special investigation and charge an investigation fee on top of the permit fee. A fourth violation by the same person raises that fee to ten times the scheduled amount. Ask the counter before a crew starts digging.
