Concrete Companyin Santa Monica, CA
A concrete company in Santa Monica can pour private walks and driveways up to 30 inches above grade without a building permit, but front yards are capped: paving may cover only half of the required front setback, and parking pads are not allowed there. Coastal Zone and historic addresses add their own approvals.
Concrete in Santa Monica is mostly repair and replacement. By the 2024 American Community Survey, 71.7 percent of the city's 54,322 homes predate 1980, yet only 20.7 percent are single-family detached, so a typical job is a driveway, a path or a patio behind a house on a modest lot, or shared paving at a small building. The city also sits on a coastal plain where County map layers carrying State hazard zones show liquefaction in a strip near the shore, which makes soil part of the conversation.
MDG Builders, CSLB #1040337, is a general contractor based in Tarzana. We lay out the pour, take the permit questions to the City and sequence the crews, and a subcontractor licensed for concrete forms and finishes the slab, with its license and insurance certificate available on request. Prices live on our concrete page; the Santa Monica overview shows our other work in the city, from flooring to decks.
What Santa Monica's code and Permit Services Center say about concrete
Where concrete permits come from in Santa Monica: City of Santa Monica Community Development Department, Building and Safety Division.
- SMMC 8.08.050(c)(7) exempts platforms, walks and driveways not more than 30 inches above grade and not over a basement or story below, and the City's permit page lists concrete or asphalt patios and driveways built on natural grade as exempt. A grading permit is not required for an excavation under 2 feet deep, a cut slope not over 5 feet high steeper than 1 to 1.5, or a fill under 1 foot on natural terrain flatter than 1 to 5 (SMMC 8.08.050(d)).
- The City's front yard paving table says a Single Trade Permit applies if a permit is necessary, with City Planning as reviewer and Same-Day review unless tied to a prior Architectural Review Board approval (then Minor Plan Review). It says R1 properties must comply with SMMC 9.07.030 even when no permit is needed, and that paving for off-street parking is not allowed in the front setback.
- SMMC 9.07.030 limits front setback paving to 50 percent of the required front setback area on parcels 25 feet or wider (60 percent on narrower parcels), allows only one driveway on parcels under 100 feet wide, and limits excavation in the front setback for a driveway, stairway or doorway to 3 feet below existing grade.
- On a Landmark or in a Historic District, SMMC 9.56.210 treats repairing or repaving flat concrete in side and rear yards, and repaving existing front yard paving, walkways or concrete in the same material and appearance, as ordinary maintenance with no certificate of appropriateness. In the Third Street Neighborhood Historic District, front yard paving that changes appearance needs a certificate of administrative approval (SMMC 9.58.020).
- Work that affects a sidewalk, alley or public street needs a separate construction permit from Public Works, and the City lists Encroachment Permits and Temporary Traffic Control Plans under its Construction Permits menu. The City's new-development tables also point to urban runoff mitigation for new structures of 500 square feet or more and tree protection where a property lacks alley access.
- SMMC 8.12 limits prescriptive footings for light-frame construction to one story above grade and bars prescriptive design of concrete and masonry foundation walls for structures assigned to Seismic Design Category D, E or F, and it amends concrete special inspection rules, so foundation work on such structures follows an engineered design. Which Seismic Design Category a given Santa Monica lot falls in was not stated on the pages read.
How much of the front setback can a Santa Monica driveway or patio cover?
Less than most owners expect. SMMC 9.07.030 limits paving in the front setback to 50 percent of the required front setback area on parcels 25 feet wide or more, and to 60 percent on narrower parcels. It also allows only one driveway on a parcel under 100 feet wide and limits excavation in the front setback for a driveway, stairway or doorway to 3 feet below existing grade.
The City's permit pages add that a Single Trade Permit applies for front yard paving if a permit is necessary, with City Planning as the reviewer, and that paving for off-street parking is not allowed in the front setback. R1 properties must meet 9.07.030 even when no permit is needed. A plan to widen a driveway or add a pad beside the house is a zoning question before it is a concrete one.
The limit applies to the required front setback, which comes from the Official Districting Map or defaults to 20 feet in R1, not to the whole yard. On a parcel 50 feet wide with a 20 foot setback, that strip is 1,000 square feet, so half of it is 500 square feet of paving, by our arithmetic. Measure what is already poured before drawing anything new.
- How wide is the parcel, and which percentage applies?
- How much paving already sits in the front setback?
- Does the plan include parking in the setback, which the City bars?
Is a building permit needed for flatwork on natural grade in Santa Monica?
Usually not for flat work on natural grade. The exemption in section 8.08.050 of the Municipal Code covers walks and driveways up to 30 inches above grade that do not sit over a basement or another story, and the City's permit page also lists concrete or asphalt patios and driveways built on natural grade. Exempt work must still meet the codes, and the City adds zoning and parking design standards.
Grading has its own line. A grading permit is not needed for an excavation under 2 feet deep, a cut slope not over 5 feet high and steeper than 1 to 1.5, or a fill under 1 foot on natural terrain flatter than 1 to 5. A deeper dig for a thick base can cross that line, so ask the Permit Services Center before the excavator arrives.
Public Works is separate. Work that affects a sidewalk, alley or public street needs its own construction permit, and the City lists encroachment permits and temporary traffic control plans on its permit menu, so ask whether a new approach at the curb counts. Projects valued at $50,000 or more, or 1,000 square feet or more, need a Construction and Demolition Waste Management Plan with a security deposit.
Does a pour in Santa Monica's Coastal Zone or a landmark district need extra approval?
The City places much of Downtown, the Third Street Promenade included, in its Coastal Zone. Its Local Coastal Program stops at a 1992 Land Use Plan and has no Implementation Plan, so the Coastal Commission, not the City, still decides coastal permits, and a June 2026 City release sets a goal of certifying a full program by the end of 2027. Under SMMC 8.08.070 a building permit cannot issue for any project that still needs a coastal development permit. We did not find the boundary map or an exemption list, so we make no claim about your block; confirm the address before promising a pour date.
Historic rules are easier to read for paving. On a landmark or in a historic district, SMMC 9.56.210 treats repairing or repaving flat concrete in side and rear yards, and repaving front paving or walkways in the same material and appearance, as ordinary maintenance approved by the Landmarks Commission Secretary. In the Third Street Neighborhood district, front yard paving that changes appearance needs a certificate of administrative approval under SMMC 9.58.020.
What are the retaining wall and block wall rules in Santa Monica?
A wall that holds back soil gets a simple test here: up to 4 feet, measured from the footing bottom, with no extra load from a driveway or a slope above, needs no application under the City's table and SMMC 8.08.050. Nothing over 24 inches high may stand in the visual obstruction triangle beside driveways, parking spaces, garage doors, streets and alleys.
Freestanding block walls are less clear. SMMC 8.08.050 exempts masonry or concrete walls up to 4 feet and other fences up to 7 feet, while the City's permit pages describe freestanding walls up to 6 feet as exempt, so confirm the trigger height with the Permit Services Center before a footing is dug. Zoning is plainer: in a front setback, hedges, fences and walls stop at 42 inches under SMMC 9.21.050, and side and rear walls may reach 8 feet.
Pools bring their own wall rules. Around water 18 inches or deeper, the code asks for a barrier at least 5 feet above grade with no opening over 4 inches and a self-closing gate latched at least 5 feet up, and SMMC 9.21.160 asks for a masonry wall or solid fence at least 6 feet high where a pool is less than 30 feet from a parcel line.
How do liquefaction and fault zones change a footing or foundation pour?
County map layers carrying the State's hazard zones show liquefaction at 10 of 134 sample points on land, mostly in a diagonal strip near the coast, and mapped earthquake fault zone points in a narrow band across the northern half of the city. These are point samples about 250 meters apart, not parcel maps, so they cannot say what lies under your lot.
What the City asks is more concrete. Its tables require a soils report for 750 square feet or more of new or added floor area on hillside, seismic or fault-hazard properties, and SMMC 8.12 sets special design requirements inside its Seismic and Geologic Hazard Zones. It limits prescriptive footings for light-frame buildings to one story above grade and bars prescriptive design of concrete and masonry foundation walls for Seismic Design Category D, E or F, which means an engineered design. None of the City pages we read names a Seismic Design Category for a particular lot. New structures of 500 square feet or more also trigger urban runoff mitigation, and tree protection applies where a lot has no alley access.
What does a concrete company charge in Santa Monica, and when can crews pour?
No Santa Monica price study exists in our sources, so we use the Los Angeles working ranges from our concrete page. A plain patio, walk or slab of 300 square feet or more runs $8 to $14 a square foot, and a driveway replaced with the old slab demolished runs $9 to $20. Decorative work, meaning staining, stamping or exposed aggregate, costs $15 to $30 a square foot in the same sources. Confidence is medium for plain flatwork and medium to low for decorative work, and jobs under 300 square feet tend to cost more per foot because of minimum charges.
Hours are tight. SMMC 4.12.110 bars construction before 8 a.m. or after 6 p.m. on weekdays, before 9 a.m. or after 5 p.m. on Saturdays, all day Sunday and on eight listed holidays, so a pour that starts late can run into the cutoff. Every permitted site needs a bilingual English and Spanish sign, and a development project within 500 feet of homes must submit a noise-mitigation list before its permit issues.
Rain falls mostly from December through March, 11.05 of the year's 13.45 inches at the airport station, so the dry months are the easy ones for a pour, and May through October each average under an inch.

What concrete costs around Santa Monica
The ranges here are our Los Angeles figures from the concrete page, not a Santa Monica quote, and retaining walls have no published per-foot price because height, drainage, footing, steel and engineering set it. Demolition and haul-off, soils reports, engineering and permits are separate lines in a proposal, and our license check guide walks through looking up a contractor's number. A slab often goes with flooring in Santa Monica or a Santa Monica deck. Culver City, Beverly Hills and West Hollywood apply their own codes, and concrete in Los Angeles, concrete in Inglewood, concrete in Glendale and concrete in Pasadena show how far they differ.
| What it covers | Typical range |
|---|---|
| Patio, walkway or slab, broom finish, 300 sq ft or more | $8 to $14 per square foot |
| Decorative: stained, stamped or exposed aggregate | $15 to $30 per square foot |
| Driveway replacement, with demolition of the old slab | $9 to $20 per square foot |
| 20 by 20 foot plain patio (400 sq ft) | About $3,200 to $5,600 |
| 20 by 20 foot decorative patio (400 sq ft) | About $6,000 to $12,000 |
| Small jobs under 300 sq ft | Usually above the per-foot range |
| Retaining walls | Set by the written proposal |
Other work we manage in Santa Monica
Santa Monica concrete questions: permits, front yards and soil
Can I pour a concrete patio without a permit?
Usually yes for a patio on natural grade, because the City lists concrete and asphalt patios on natural grade among exempt work and the code exempts walks and driveways up to 30 inches above grade. The work must still meet zoning, including front setback paving limits, so confirm with the Permit Services Center first.
Can I expand my driveway without a permit?
Zoning decides before the permit does. In R1, front setback paving is limited to 50 percent of the required area on parcels 25 feet wide or more, only one driveway is allowed on a parcel under 100 feet wide, and paving for off-street parking is not allowed in the front setback. Ask City Planning with your parcel width.
How much should a 20x20 concrete patio cost?
Using our Los Angeles ranges, a plain 400 square foot patio runs about $3,200 to $5,600 and a decorative one about $6,000 to $12,000. Those figures are multiplication on medium and medium to low confidence sources, not a bid. Demolition, haul-off, drainage and permits are separate, and small jobs usually price higher per square foot.
How much does a concrete driveway cost in Santa Monica?
We found no Santa Monica study. Our Los Angeles range for a driveway replaced with the old slab demolished is $9 to $20 per square foot, which Angi's 2026 pages and our working notes support at medium to low confidence. What moves the price is thickness, haul-off, grading and whether the curb approach is included.
What is the tallest retaining wall you can build without a permit in Santa Monica?
Four feet from the footing bottom, provided the wall carries no surcharge such as a driveway or a slope above it. Above that, or with a surcharge, expect plans and review. Fences are different, and the City's sources disagree on their height line, so confirm before building.
Is 4 inches of concrete thick enough for a driveway?
We found no Santa Monica rule on thickness, and our research treats 4 inches as common practice for patios and walks rather than a code figure. A driveway that carries trucks or sits on weak soil may call for more depth or steel. Ask the proposal to state thickness, base and reinforcement in writing.
Do concrete jobs in the Santa Monica Coastal Zone need a coastal permit?
We cannot say for a given block, because we did not find the Coastal Zone boundary map or a list of exempt work. The City says the zone covers much of Downtown, and the Coastal Commission still decides coastal permits. Ask the City whether your address is inside the zone before scheduling a pour.
Can I repave a driveway at a Santa Monica landmark or historic district home?
Often yes as ordinary maintenance, if the material and appearance stay the same. SMMC 9.56.210 lets the Landmarks Commission Secretary approve such repaving, and in the Third Street Neighborhood district, front yard paving that changes appearance needs a certificate of administrative approval. A new pattern or width needs a conversation with City Planning first.
What license should a Santa Monica concrete company hold?
Class C-8 on the CSLB list is the concrete license, and C-29 is masonry, which includes concrete block walls. Ask for the license number, verify it with our license check guide, and request a certificate of insurance. Any contract over $500 needs to be in writing and signed before work starts.
