Concrete Companyin Irvine, CA
A concrete company in Irvine checks the lot first. Walks and driveways up to 30 inches above grade are exempt from a building permit, retaining walls up to 4 feet are exempt without a surcharge, and grading starts at 50 cubic yards or two feet deep. Zero lot line easements and HOA rules can still say no.
Irvine's concrete is mostly young. The Irvine Ranch, which James Irvine had assembled to about 110,000 acres by 1878, became a planned city of villages split by six-lane arterials, and Census estimates for 2024 put about 54 percent of the 121,814 homes in the year 2000 or later, about 21 percent before 1980 and only about 5 percent before 1970. A driveway poured in Northwood or Turtle Rock in the 1970s is close to 50 years old, while a Portola Springs or Orchard Hills pad is recent, and the questions differ for each.
MDG Builders, CSLB #1040337, is a Tarzana general contractor that plans the job, takes the setback questions to Irvine's Building and Safety office and Planning Counter and hires a licensed concrete subcontractor for the forms, the pour and the finish. Finishes and ranges are on the concrete page, and the Irvine overview covers the other trades we manage here.
What Irvine's Building and Safety office, Planning Counter and HOA rules say about concrete work
Where concrete permits come from in Irvine: City of Irvine Community Development Department, Building and Safety (Permit Processing Center).
- The City's Permits Not Required page exempts platforms, walks and driveways not more than 30 inches above grade and not over any basement or story below. Retaining walls 4 feet or less (footing bottom to wall top, no surcharge) and prefabricated pools with walls entirely above grade and 5,000 gallons or less are also exempt, with pool equipment and the pool at least 2 feet from any property line.
- City Informational Bulletin 220 says a grading permit is required when an excavation exceeds 50 cubic yards or two feet in vertical depth (not counting foundation excavation) or when compacted fill is placed to support structures. The same bulletin lists slope proximity and liquefaction potential among the conditions that can require a soil report.
- The City's patio cover page says a zero-lot-line patio cover or gazebo (more common in Turtle Rock and University Park) may not be built within an easement area, so footings and slabs on those lots need the recorded easement checked first.
- CSLB defines the C-8 Concrete classification as forming, pouring, placing, finishing and installing mass, pavement, flat and other concrete work, excluding contractors whose sole business is plaster coatings or placing reinforcing steel.
Where can concrete go on a zero lot line lot in Turtle Rock or University Park?
Not inside the easement, and the recorded easement says where that is. The City's patio cover page says a zero lot line patio cover or gazebo, more common in Turtle Rock and University Park, may not be built within an easement area. The page speaks of covers, but a footing is part of one, so a footing or slab on those lots needs the recorded easement read first. The title paperwork from the purchase, or the Planning Counter, is the place to start.
Easements also limit what hangs over a pad. The City says they restrict eaves, gutters and patio covers, and that an eave is banned over an easement narrower than 3 feet, which matters when a new walk or slab runs along the house wall.
Shady Canyon is a third pattern, with larger side setbacks than typical Irvine lots and a 15 foot setback in the 2.1A district, per the City's patio cover page. The Development Assistance Counter at 949-724-6308 can give the setbacks and easements for a specific lot before anyone stakes a pour.
Do you need a permit to pour a driveway, walkway or patio in Irvine?
Often not for the slab itself. Under the City's Permits Not Required page, platforms, walks and driveways no higher than 30 inches above grade, and not over any basement or story below, need no building permit, which covers most flatwork. It does not say whether a decorative patio slab qualifies in a given setback, so we cannot promise it, and zoning still governs where the slab may go.
Our reading has a gap. The Irvine Zoning Ordinance sits on Municode, which returned an access error to our tools, so we read the City's project pages and not Chapters 3-35 or 3-37 themselves. For buildings, the City's addition page gives typical setbacks of 15 feet at the front, 5 feet at the side and 10 feet at the rear, and says they vary by zoning district.
Public property is separate. A driveway apron and sidewalk sit in the City's right of way, and we did not read Irvine's rules for that, so ask who issues the permit and which inspection applies before the old apron comes out.
- Is the surface 30 inches or lower above grade?
- Does the slab touch a recorded easement?
- Does any of it sit in the right of way?
When does concrete work in Irvine need a grading permit or a soil report?
A grading permit is required when an excavation passes 50 cubic yards or two feet of vertical depth, not counting foundation excavation, or when compacted fill supports a structure, according to City Bulletin 220. A 400 square foot patio dug 4 inches stays near 5 cubic yards, far under the volume trigger. The two foot depth is the likelier one, for a sunken seating area or a wall footing on a slope.
The same bulletin lists slope proximity, unfavorable soils and liquefaction potential among the conditions that can require a soil report for an addition. We found no sentence that applies that list to a stand-alone slab, but it shows what the City looks at when a pad or wall sits near a slope or carries load.
We read no flood, liquefaction or expansive soil map for Irvine, so we do not say which villages have which soil. The builder's original grading report, or a geotechnical report for the lot, is the document to ask for.
How tall can a retaining wall or block wall be in Irvine before the City wants plans?
Four feet is the line for the wall alone. The City applies the state exemption that lets a retaining wall of 4 feet or less, measured from the bottom of the footing, skip a permit unless it carries a surcharge. Bulletin 185 gives an ascending slope, another wall, a building or a driveway as surcharges, and measures fence height from the lowest finished grade on either side.
Fence and wall height has a conflict. The City's fence page says a front-setback wall starts at 2.5 feet at the property line and rises one foot for each three feet of setback, up to 7 feet. Bulletin 185, revised November 2, 2020, caps residential fences and walls at 6 feet, and lets a retaining wall combined with a fence reach 10 feet along the street side and 12 feet at the rear. Ask the Planning Counter at 949-724-6308 which applies, because the building permit exemption for fences under 7 feet does not lift zoning limits.
Materials are limited too. Irvine bans plain exposed concrete block, chain link, plastic, barbed wire and grape stakes as fence materials, per Chapter 3-35 as the bulletin summarizes it. CSLB's C-29 masonry class covers block walls, so a finished block wall may be a different crew than the one pouring your slab, as our subcontractor guide explains.
Do Irvine HOAs control driveway, patio and walkway changes?
Often, and the City says so. Its HOA page lists associations for single-family neighborhoods, condominium communities and high-rise condominiums, and says areas without an HOA, including parts of Lower Peters Canyon, Northwood and El Camino Real, can still be under recorded CC&Rs. The City's own examples of what they control are exterior paint colors and room additions, so ask whether a wider patio or a new walkway counts.
A City permit does not settle it. Approved plans for a single-family home carry a Community Association Advisory saying the permit does not relieve you of HOA approval, and a condominium owner must supply the HOA's design approval letter with the application.
Each village has its own architectural theme, per Wikipedia: Woodbridge Atlantic Coast, Northwood Bungalow and Craftsman, University Park California Modern, Westpark Italian Riviera and Mediterranean, Quail Hill Spanish and Tuscan. We found no village's actual rule on concrete color, stamping or paving, so ask the association for its guidelines before choosing exposed aggregate or a stamped pattern.
Is it a bad idea to pour concrete in Irvine heat or winter rain?
Heat depends on where in the city you pour. NOAA's Irvine Ranch station records 61.6 days a year at or above 90 F and 7.5 at or above 100 F, with August highs averaging 90.2 F, while John Wayne Airport, 5.5 miles west, averages 80.4 F in August. On a hot, dry afternoon, ask how the crew will keep the slab damp and cured, and who is on site to finish it before it stiffens.
Rain is a winter matter. The Irvine Ranch station averages 13.06 inches a year, 10.18 of them from December through March, on 24.5 days with measurable rain, and only 0.09 and 0.01 inch in July and August. A pour between December and March needs a plan for covering the surface and a fallback date, and one in August needs the heat plan.
What does concrete work cost in Irvine, and what license should the crew hold?
No Irvine price study turned up, so these are Los Angeles figures from Angi's 2026 pages, which Angi builds from customer surveys and pro data, and Orange County pricing may differ. Angi puts a patio at $4 to $13 per square foot, averaging $5,248, a 20 by 20 foot patio at $1,600 to $5,200, stamped work at $15 to $30 and a driveway at $8 to $20, averaging $7,270. A retaining wall averages $7,140 with a range of $2,674 to $11,842, and we print no per-foot wall price because height and drainage drive it.
Federal wage data for the Los Angeles-Long Beach-Anaheim metro area, which includes Orange County, show cement masons averaging $33.67 an hour in May 2025. That is a wage and not a billing rate, and demolition, base, rebar and haul-off belong on separate proposal lines.
A concrete company should hold CSLB's C-8 class. On permitted work the City asks for a City of Irvine business license, and our license check guide shows how to look up the rest.

Irvine concrete questions, answered
Can I pour a concrete patio without a permit in Irvine?
Possibly, but we cannot confirm it from a City sentence. The City exempts platforms, walks and driveways up to 30 inches above grade, and does not say whether a decorative patio slab qualifies in a given setback. Call the Planning Counter at 949-724-6308 with the size and the distance to each property line.
Can I replace my driveway without a permit in Irvine?
Often the slab is exempt: the City's list covers driveways not more than 30 inches above grade. The apron and sidewalk sit in the right of way, and we did not read Irvine's rules for that, so ask which permit applies. Your HOA or CC&Rs may also need to approve a change.
What is the maximum height of a retaining wall without a permit in Irvine?
Four feet, measured from the bottom of the footing, unless the wall carries a surcharge such as a slope, a driveway or a building. Zoning heights still apply, and the City's fence page and Bulletin 185 disagree between 7 and 6 feet, so ask the Planning Counter before you dig.
How much should a 20x20 concrete patio cost in Irvine?
A 20 by 20 foot patio, 400 square feet, runs $1,600 to $5,200 on Angi's 2026 Los Angeles page, inside a general $4 to $13 per square foot. No Irvine study turned up. Tear-out, base work and decorative finishes shift the total, so the price comes after a site visit.
How much does a concrete driveway cost in Irvine?
On Angi's 2026 Los Angeles page a driveway runs $8 to $20 per square foot, averaging $7,270 across a $3,067 to $16,472 range. Taking out the old slab, grading and apron work change that, and an HOA may need to approve first, so ask who files what.
How much does a stamped concrete patio cost in Irvine?
Stamped work is $15 to $30 per square foot on Angi's 2026 Los Angeles page, averaging $5,948. Patterns, colors and sealers vary widely, so we trust that figure less than the plain flatwork range. Put pattern, color and sealer in writing so bids compare, and read your village's design guidelines.
Can I pour concrete on a zero lot line lot in Irvine?
Yes, but not within the recorded easement. The City says a zero lot line patio cover or gazebo, common in Turtle Rock and University Park, cannot sit in an easement area, so footings and slabs need the recorded easement checked first. The Development Assistance Counter at 949-724-6308 can help.
Does my HOA have to approve a new concrete patio or driveway in Irvine?
Check your documents. The City says HOAs and recorded CC&Rs can control exterior changes, and that a City permit does not relieve you of HOA approval. Condominium owners must give the City the HOA's design approval letter. We found no village's rule on paving, so ask the association directly.
How high can a block wall be in Irvine?
It depends on the setback. The City's fence page allows up to 7 feet after the 2.5 foot start and one foot per three feet formula, while Bulletin 185 caps walls at 6 feet. Plain exposed concrete block is banned as a fence material, so ask the Planning Counter and plan a finished wall.
What license does a concrete company need in Irvine?
A concrete company should hold CSLB's C-8 class for flatwork and foundations, and block walls fall under C-29. For concrete work that needs a permit, the City asks to see a City of Irvine business license, a CSLB pocket card and a workers' compensation certificate or exemption.
