Concrete Companyin Tustin, CA
A concrete company in Tustin starts with the soil and the permit line. Flatwork under 30 inches above grade generally needs no building permit, and the City's guide asks for 6 inches of concrete on compacted subgrade. Additions need a soils report unless they are small and outside a liquefaction zone, and retaining walls over 2 feet need plans.
Most of Tustin's concrete went down when the groves came out. Citrus quick-decline disease pushed growers to sell after the Santa Ana Freeway arrived in 1955, and tracts such as Lockwood Park Place (about 1952), Raleigh Place (1954) and other tracts from 1952 to 1956 followed. The 1960s are the biggest decade in Census estimates for 2024, with 7,131 of 30,118 homes, so a great many driveways and patio slabs are now 55 to 70 years old. Newer ground at Tustin Ranch and Tustin Legacy raises different questions than a 1950s lot near Old Town.
MDG Builders, CSLB #1040337, is a Tarzana general contractor that plans the job, takes the setback and soils questions to Tustin's Building Division and hires a licensed concrete subcontractor for the forms, the pour and the finish. Finishes and ranges are on the concrete page, and the Tustin overview covers the other trades we manage here.
What Tustin's Building Division, its walkway and wall handouts and state law say about concrete work
Where concrete permits come from in Tustin: City of Tustin Community Development Department, Building Division.
- The City's walkways and slabs guide (June 1999) says concrete flatwork has a minimum thickness of 6 inches, a six-sack type 5 cement mix of at least 2,500 psi at 28 days, and subgrade compacted to 90 percent of maximum density, and that flatwork does not generally need a building permit when it is not part of a new subdivision, sits less than 30 inches above grade and is not over a basement. Removing or altering existing improvements may require a permit.
- The same guide says all water on the site must drain to the street and storm drain system, water may not be directed onto adjacent properties, existing swales and yard drains must be respected, and that a plumbing permit and backflow preventers are required for irrigation systems.
- The room additions exempt list covers open or unroofed concrete patio slabs, driveways and wood decks not more than 30 inches above grade and not over a basement or story below. The City's Building FAQ says a grading permit is needed above 50 cubic yards of earth moved, one foot of fill or a cut slope over 5 feet.
- Ordinance No. 1569 requires pools to be built to an engineered design for expansive soils unless a soils report says otherwise, at least 7 feet from the top and 5 feet from the toe of a cut, fill or natural slope, with continuous special inspection of reinforced gunite or cast-in-place concrete and a 2,000 psi minimum at 28 days.
- 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.
What does Tustin's soils report policy mean for a new slab or foundation?
It decides whether the footing is a standard detail or an engineered one. The City's Soils Report Policy for one and two family additions asks for a soils report on every addition except a few cases. An addition under 500 square feet outside a liquefaction zone can use a set recipe: 1,500 psf bearing, 18 inch footings with two #5 bars top and bottom, and a 5 inch slab with #4 bars at 24 inches.
From 500 to 1,000 square feet outside a liquefaction zone the same recipe applies, plus a geotechnical engineer's certification before the foundation inspection. A detached garage, or a second story built within the existing footprint, skips the report as well, and near a slope the plan check engineer can ask for more. A retaining wall holding back up to 6 feet with no surcharge also needs no soils report.
Tustin lies on the Santa Ana River plain, and its masonry notes call for 24 inch footings in a liquefaction zone. We did not read a liquefaction map for any parcel, so the Building Division is the place to ask which side a lot falls on.
Do you need a permit to pour a driveway, walkway or patio in Tustin?
Often no, with limits. The City's walkways and slabs guide says concrete flatwork does not generally need a building permit when it is not part of a new subdivision, sits less than 30 inches above grade and is not over a basement. A guide to room additions lists open, unroofed patio slabs and driveways on the same exempt line. Removing or altering existing improvements may still need a permit.
Digging has its own trigger. The Building FAQ requires a grading permit when more than 50 cubic yards of earth moves, when one foot of fill goes in, or when a cut slope tops 5 feet, with four sets of grading plans and two preliminary soil reports. If a permit does apply, the City's documents disagree on its life: 180 days, 360 days or 12 months depending on the page, so ask which clock governs.
Plan carefully for the truck, too. Ordinance No. 1569 bars materials, debris and dumpsters from public property without the City Engineer's written approval. We found no Tustin document that spells out a driveway approach permit, so ask Public Works before cutting the curb.
- Is the slab under 30 inches above grade?
- Does the job move over 50 cubic yards of earth?
- Will the approach or sidewalk be cut?
How thick should a Tustin driveway or patio be, and does the weather matter?
The City's walkways guide sets a floor: concrete flatwork at least 6 inches thick, a six-sack type 5 cement mix of at least 2,500 psi at 28 days, and subgrade compacted to 90 percent of maximum density. That guide is dated June 1999, so a contractor proposing 4 inches should explain why in writing and show that the Building Division agrees.
Weather sets the schedule more than the spec. NOAA's 1991 to 2020 normals for the Irvine Ranch station show 13.06 inches of rain a year, 10.18 of them from December through March, and 61.6 days at or above 90 F. John Wayne Airport, on the cooler coastal side, averages 12.8 such days. Ask the finisher how the crew will cure the slab on a 95 degree afternoon and what happens if a winter storm arrives mid-pour.
Pools are the one concrete item with a firm number in the 2025 ordinance. Ordinance 1569 requires an engineered design on expansive soils, at least 7 feet from the top and 5 feet from the toe of a slope, with continuous special inspection of the gunite or cast-in-place shell and a 2,000 psi minimum at 28 days.
Where does the water go when you pour a new patio or walk in Tustin?
To the street and the storm drain, never onto the neighbor. The City's walkways guide states that all water on a site must drain that way and that existing swales and yard drains must be respected. A patio poured flat against a house, or a new walk that dams a swale, creates the problem the guide warns about.
Engineered tract lots depend on those swales. Slope the slab away from the house wall, and keep a planter or fence footing from blocking a yard drain. If an irrigation line is moved during the work, the guide requires a plumbing permit and backflow preventers.
A site with a slope, a pool or an easement needs more than a hose test. Ask the crew for the finished fall in inches over the run, and ask who owns a fix if water pools after the first rain. Our guide on how general contractors use subcontractors explains how a written scope binds each trade.
How tall can a block wall, fence or retaining wall be in Tustin?
The City's fence guide caps fences, hedges and walls at 6 feet 8 inches, and nothing over 3 feet may stand in a required front yard setback. A permit and zoning check are required over 3 feet, walls over 6 feet may need engineering, and a wall on a shared line needs the neighbor's consent. Ordinance No. 1569 instead exempts fences up to 6 feet, so on a 4 to 6 foot wall ask the Building Division which document governs.
Retaining walls follow a separate guide from June 1999: a permit above 2 feet from finish grade to top, or with a surcharge, plus Planning design review and footing, pre-grout, pre-backfill and final inspections. The Planning FAQ also names garden walls of 3 feet or higher.
Block walls come with soil notes. Footings go 12 inches into undisturbed soil, 24 inches with two #5 bars top and bottom in a liquefaction zone, with fully grouted cells and type V cement at 4,500 psi for corrosive soil unless testing allows type II at 2,500 psi. CSLB's C-29 masonry class covers concrete block walls.
Does a walk, wall or driveway in Old Town Tustin need a Certificate of Appropriateness?
Flatwork may not, but a wall or anything needing a building permit can. The Cultural Resources Overlay District, set up by Ordinance No. 1001 on June 20, 1988, requires a Certificate of Appropriateness for exterior alteration or construction that needs a City building permit, with an exception for ordinary maintenance that does not change design, material or original appearance. The district covers the original 1870 townsite and carries homes from the 1870s and 1880s.
We read that language in a Zoneomics copy of the Tustin City Code, since the City's official code host was not read, so confirm the current wording with Planning at 714-573-3140. The City's code also adds findings for demolishing or moving structures built before 1940.
Old Town's street grid runs to the compass points, unlike the rest of Tustin. A replacement walk that keeps the old path and finish is a different request from a new retaining wall, so describe both clearly when you call.
What does concrete work cost in Tustin, and what license should the crew hold?
No Tustin price study turned up, so these are Los Angeles figures from Angi's 2026 pages, which we rate medium for plain flatwork and lower for the rest. Orange County prices can differ. Angi's patio page, from August 2026, shows $4 to $13 per square foot, its stamped page from July 2026 shows $15 to $30, and its May 2026 driveway page shows $8 to $20 with an average of $7,270. Small jobs run higher per foot because of minimum charges.
Labor data does cover Tustin's metro area. Federal estimates for May 2025 in the Los Angeles-Long Beach-Anaheim area put cement masons at an average of $33.67 an hour and construction laborers at $30.39, which are wages and not billing rates. We publish no retaining wall price per foot, because no independent source supports one.
CSLB's C-8 class covers forming, pouring and finishing flat and other concrete work, and excludes firms that only place reinforcing steel. Our license check guide shows how to look a license up.

Tustin concrete questions, answered
Can I pour a concrete patio without a permit in Tustin?
Usually, if it is an open slab less than 30 inches above grade and not over a basement. The City's walkways guide and its room additions list both treat that flatwork as exempt. Drainage still has to reach the street, an HOA may need to approve it, and a permit applies if the work alters existing improvements.
Can I replace my driveway without a permit in Tustin?
Often yes for the slab on your lot, since driveways under 30 inches above grade are on the City's exempt list. Removing or altering existing improvements may still need a permit, and we found no Tustin document on the apron in the public right of way, so ask Public Works before cutting the curb.
What is the maximum height of a retaining wall without a permit in Tustin?
Under the City's June 1999 retaining wall guide, a permit is needed once a wall exceeds 2 feet from finish grade to top, or if it supports a surcharge. Planning's FAQ also names garden walls of 3 feet or higher. Those handouts are old, so confirm the current rule with the Building Division.
How much should a 20x20 concrete patio cost in Tustin?
At Angi's Los Angeles range of $4 to $13 per square foot, 400 square feet runs $1,600 to $5,200 before demolition, base or rebar changes. Stamped work at $15 to $30 per square foot would reach $6,000 to $12,000. These are medium confidence planning ranges, not a Tustin bid.
How much does a concrete driveway cost in Tustin?
Angi's May 2026 Los Angeles page shows $8 to $20 per square foot and an average of $7,270 for the project. We found no Tustin study. Hauling, grading and any work on the apron belong on separate proposal lines, so a visit sets the real number.
Do I need a soils report for a concrete slab or addition in Tustin?
For an addition, usually yes. Tustin's policy exempts only additions under 1,000 square feet outside a liquefaction zone that follow its set footing recipe, plus detached garages and added stories that do not enlarge the footprint. Between 500 and 1,000 square feet a geotechnical engineer must certify before the foundation inspection.
How high can a block wall or fence be in Tustin?
The City's fence guide caps fences, hedges and walls at 6 feet 8 inches, with nothing over 3 feet in a required front yard setback. Permits start at 3 feet in that guide, while Ordinance No. 1569 exempts fences up to 6 feet, so ask the Building Division which rule governs a 4 to 6 foot wall.
Do I need a Certificate of Appropriateness for concrete work in Old Town Tustin?
Only if the work needs a building permit and alters the exterior. The Cultural Resources Overlay District requires the certificate for that kind of exterior work, with an exception for ordinary maintenance. Open flatwork is generally permit-exempt, but walls are not always, so confirm with Planning at 714-573-3140 before starting.
What license does a concrete company need in Tustin?
Poured flatwork belongs to CSLB's C-8 concrete class, and concrete block walls to C-29 masonry. A job that needs any permit cannot use the $1,000 unlicensed exemption. Look the license up on the CSLB site before signing, and ask for each subcontractor's license number and certificate of insurance.
