Concrete Companyin La Mirada, CA
A concrete company in La Mirada works inside City limits on the lot: a driveway runs 10 to 22 feet wide and may take no more than half the frontage, and at least half the required front yard must stay pervious. No City page says whether a slab or walk needs a building permit, so ask first.
Much of La Mirada's flatwork is likely as old as the houses around it. Thirteen tracts held 7,800 homes by 1956, the City incorporated in 1960 as Mirada Hills, and the Census Bureau's 2024 five-year tables show 64.4 percent of today's 15,701 homes were built between 1950 and 1969. Roots, settling and decades of cars have worked on those driveways and walks since, and the City's property maintenance code names cracked driveways, sidewalks and private roads as substandard, so a good share of the work here is replacement rather than new pours.
MDG Builders, CSLB #1040337, is a general contractor in Tarzana, and the pour is done by a licensed concrete subcontractor under our contract, not by a crew of ours. We measure the lot, work out which approvals apply with the Building and Safety Division and the Planning Division, and hold the schedule; the subcontractor's license number and insurance certificate are yours to ask for. Mixes, joints and finishes are covered on our concrete page, and the La Mirada overview lists the other trades we handle here.
What La Mirada's City pages say about concrete work
Where concrete permits come from in La Mirada: City of La Mirada Community Development Department, Building and Safety Division.
- At least 50 percent of the required front yard of a single-family lot must stay pervious, and R-1 lots need at least 20 percent landscape coverage overall (Table 21.66.040 and note 1), which caps how much of a front yard can be paved or covered with concrete.
- Driveways serving detached single-family homes must be 10 to 22 feet wide (the Director may approve 32 feet for a fully enclosed three-car garage with side-by-side spaces), at least 20 feet long from the property line to the garage or carport, and with 8 feet of vertical clearance, and no more than 50 percent of the required parcel frontage may be occupied by driveways (21.68.060(b)).
- A parking space is at least 9 by 20 feet, a two-car garage at least 18 by 20 feet inside, required parking must be paved with a surface approved by the City, and RVs, boats and trailers may not be stored in the front or street-side yard except on an approved driveway or surplus parking space (21.68.060, 21.68.120 and 21.68.090).
- Decks and patios less than 30 inches above natural grade, not over a basement or story below, and unenclosed except for a railing up to 42 inches are exempt from the accessory structure chapter (21.60.030(3)); the City's list of permit-triggering work does not name flatwork, so homeowner permit rules for slabs, driveways and walkways were not found.
- Municipal Code 12.08.080 bars pouring a concrete, asphalt, brick or gravel sidewalk or otherwise filling the ground around a City parkway tree so its roots lose air, light or water, and 12.08.090 limits excavation inside the tree protection barrier to hand tools and small hand-held power tools; concrete work near parkway trees needs the Director's protection conditions.
- Clear vision: no fence, wall or landscape material above 42 inches may stand in the 15-foot triangle at driveways and corners (21.62.050), so driveway gates, walls and planters beside new concrete must respect it.
- Paved areas are held to maintenance standards (21.72.050(f)): driveways, sidewalks and private roads showing cracks, potholes or deterioration are substandard and must be repaired or sealed.
- For parking areas, resurfacing, slurry coating or restriping needs a zoning clearance, while repair of holes and cracks and replacement of damaged planters and curbs in the same place are exempt (21.68.030 and 21.68.040).
Does concrete work like a patio, slab or walkway need a permit in La Mirada?
No City page says so either way. The Building and Safety page names garages, open patio covers, fences and accessory buildings as permit work, but it never mentions flatwork and posts no exemption list. The 2022 California Building Code lists sidewalks and driveways not more than 30 inches above adjacent grade, and not over a basement or story below, among its permit exemptions. Whether the County amendments the City adopted keep that line was not stated on any page we read, so a call to (562) 943-0131 comes before the saw cut.
Other approvals attach to the pour whatever the building answer is. A grading permit is separate when soil is imported or exported or when grading is in an area designated hillside, and on parking areas resurfacing, slurry coating or restriping needs a zoning clearance while repairing cracks and holes in place does not. The City's residential permit form is also where you state the cost of the work and, if a retaining wall is involved, its length and height.
Plan check runs through Los Angeles County at its Norwalk or Alhambra office, and inspection requests are phone only during counter hours. Ask whether the footing or the steel must be seen before concrete arrives, and book that visit first, so the truck waits behind the inspector instead of the other way around.
How wide can a concrete driveway be in La Mirada?
Under Municipal Code 21.68.060, a driveway for a detached house runs 10 to 22 feet wide, at least 20 feet long from the property line to the garage or carport, with 8 feet of vertical clearance, and all driveways together may occupy no more than half the parcel frontage. The Director may approve 32 feet for a fully enclosed three-car garage with side-by-side spaces.
Required parking must be paved with a surface the City approves, a space measures 9 by 20 feet, and a two-car garage must be at least 18 by 20 feet inside. RVs, boats and trailers may not sit in a front or street-side yard except on an approved driveway or surplus parking space, so a wider pad for a trailer is a zoning question before it is a concrete one.
The front yard has its own arithmetic. The City's table asks for 20 percent landscape coverage on R-1 lots and at least half of the required front yard pervious, and street trees are required at one per 40 feet of frontage, driveway width included. A wider driveway therefore competes with the yard and with a tree. Cerritos next door caps width a different way, and our concrete page for Cerritos shows how.
Can you pour concrete near a parkway tree or sidewalk in La Mirada?
Not carelessly. La Mirada has been a Tree City USA since 1987, and Municipal Code 12.08 bars pouring a concrete or asphalt walk that shuts off air, light or water to a City tree's roots, or piling building material around one. The Director may require a barrier at least 5 feet outside the drip line, hand tools only inside it and no cement stored there, and a tree destroyed or badly damaged must be replaced before final inspection.
A retaining wall that lowers the grade near a parkway tree must leave the ground inside the drip line at its original level and be porous enough to let roots breathe. Public Works, at (562) 902-2385, handles trees and the public right of way, and its page publishes no residential driveway approach rules or fees, so ask there when new concrete meets the curb. The code does say a new driveway approach for an ADU needs its own encroachment permit.
Sidewalks have a rule of their own. Section 12.04.010 requires curb, gutter and sidewalk to exist or be bonded before a building permit issues, which a large addition can trigger, but it excuses residential blocks where 75 percent or more of the frontage was built without sidewalks and does not force replacement of existing City-approved curb.
Which block walls and retaining walls need approval in La Mirada?
A retaining wall in La Mirada escapes the wall permit only while it stays under 4 feet from the bottom of its footing to its top and holds up no extra load, according to the City's wall chapter, Municipal Code 21.62. At 4 feet or taller, or with a driveway or building behind it, treat it as a permit job. The County's sample referral sheet adds geology and soils review where a retaining wall or slope is involved.
Height limits cap the rest: 42 inches in a front yard, 7 feet in interior and rear yards, and nothing taller than 42 inches inside the 15 by 15 foot sight triangle at corners and driveways. Chain link, razor wire and barbed wire are prohibited for new work.
A wall beside a major or minor arterial must be split-face tan block with a decorative cap approved by Planning, and wood and vinyl are barred there. If half or more of an existing arterial wall is rebuilt, changed or added to, the rules apply to the whole wall. Interior neighborhood walls may be precision block, slump stone, split face, stucco-covered block, hardwood or vinyl, with the finish approved before construction. Ask Planning whether your street counts as an arterial. CSLB lists poured work under C-8 and block walls under C-29 masonry.
How do liquefaction zones, creeks and summer heat affect a La Mirada slab or footing?
The General Plan says liquefaction is possible in the southern part of the city and in bands that follow drainage areas east to west, and its Policy 1.2 requires geotechnical studies for development on liquefaction or landslide properties. A County map layer sampled at 119 evenly spaced points inside the boundary put 26 of them, 21.8 percent, in the State liquefaction zone; that is a sample, not a parcel answer. For a patio slab the difference is small, but for a footing, a tall wall or an addition slab a soils report is the only way to know the lot.
Water is mostly a drainage matter. The Housing Element places the whole residential area in FEMA Zone X, and the General Plan says La Mirada Creek and Coyote Creek can overflow if blocked. A County sample found 15 of 119 points, 12.6 percent and all in the south, inside the Prado Dam inundation area. Slope new concrete away from the house and ask where the water goes.
Heat matters on pour day. Fullerton's normals show about 39 days a year at or above 90 degrees and about 4 at or above 100, with August highs averaging 86.7. Ask how the crew handles a hot, windy afternoon, how long the slab cures and what happens when a December to March storm is forecast. No City handout we read sets slab thickness, reinforcing or joint spacing, so those belong in your contract.
What does concrete work cost for a La Mirada patio, and how does a stamped finish change it?
Our concrete page uses $8 to $14 per square foot for plain, flat, easy-access flatwork of about 300 square feet or more, at medium confidence. Angi's 2026 Los Angeles patio page lists $4 to $13, and small jobs cost more per foot because crews charge minimums.
Multiply by area. A 20 by 20 foot patio is 400 square feet, which is $3,200 at the low rate and $5,600 at the high one in plain broom finish. The widest La Mirada driveway over its 20 foot minimum length is 22 by 20, or 440 square feet, and at our $9 to $20 driveway range with demolition that is $3,960 to $8,800.
Decorative work is another price tier. Angi's Los Angeles stamped patio page runs $15 to $30 per square foot, so those same 400 square feet would cost $6,000 at the bottom and $12,000 at the top, with pattern, color and sealer deciding where it lands. For new housing, additions and exterior remodels, the City's walkway standard asks for paths at least 4 feet wide, firm and slip-resistant; poured or stamped concrete qualifies and grasscrete is prohibited.
Does a cracked La Mirada driveway need repair, sealing or replacement, and who may do the work?
The City's property maintenance chapter, Municipal Code 21.72.050, treats driveways, sidewalks and private roads showing cracks, potholes or deterioration as substandard and calls for repair or sealing, which Code Enforcement can press. A hairline crack is a sealing job. A heaved, sunken or crumbling panel usually points to the base or the roots below, and the repair should say what is fixed down there, not only what shows on top.
CSLB's class C-8 covers forming, placing and finishing concrete, and setting reinforcing steel alone is a separate class. Section 7048 lets only jobs under $1,000 with materials skip a license, never one needing a permit. The City also wants contractors to hold a La Mirada business license, and jackhammers and saws are barred from 8:00 p.m. to 7:00 a.m. on weekdays and Saturdays and until 9:00 a.m. on Sundays.
Under section 7159, a contract over $500 must be in writing with the price and the significant materials, and the down payment is capped at $1,000 or 10 percent, whichever is less. Our guide to checking a contractor license shows how to verify a number.

What concrete costs around La Mirada
Ranges here are Los Angeles figures from our concrete page, not a La Mirada quote, and County permit fees, soils reports and demolition haul-off appear as separate lines. Nearby pages: concrete work in Cerritos, concrete work in Whittier, concrete work in Norwalk and concrete work in Los Angeles. A new patio often pairs with a deck in La Mirada or flooring in La Mirada, and how general contractors use subcontractors explains how the trades are sequenced.
| 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 |
La Mirada concrete questions: driveways, patios and walls
Can I pour a concrete patio without a permit in La Mirada?
No City page says either way, so ask Building and Safety at (562) 943-0131. The 2022 California Building Code lists low sidewalks and driveways among its exemptions, but we could not confirm that La Mirada keeps that line. A patio in the front yard must also leave at least half of the required front yard pervious.
Can I expand my driveway without a permit in La Mirada?
Not freely. A detached house's driveway must stay 10 to 22 feet wide, all driveways together may cover no more than half the frontage, and at least half the required front yard must stay pervious. Widening at the curb is a Public Works question, since its page posts no residential approach rules. Start with Planning at (562) 943-0131.
How much does a 20x20 concrete patio cost in La Mirada?
At our Los Angeles range of $8 to $14 per square foot, 400 square feet of plain broom-finished concrete lands between $3,200 and $5,600. Angi's 2026 Los Angeles patio page shows a lower $4 to $13 band, and minimum charges push small jobs higher. Demolition, drainage and permits are extra; the range is medium confidence, not a quote.
How much does a 300 square foot stamped concrete patio cost in La Mirada?
Using Angi's 2026 Los Angeles stamped range of $15 to $30 per square foot, 300 square feet comes to $4,500 to $9,000. Pattern, color, sealer and access decide where it falls, so ask to see a sample of the exact pattern. The figure is a medium to low confidence range for Los Angeles, not a La Mirada bid.
Can I build a retaining wall in La Mirada without a permit?
Only a low one. The City's wall chapter exempts a retaining wall shorter than 4 feet, measured from footing bottom to top, if it supports no extra load; a taller wall, or one with a driveway or building behind it, needs approval. County geology review can apply on slopes. Ask the counter, and ask your bidder who designs the footing and drainage.
Is 4 inches of concrete thick enough for a driveway?
No La Mirada page we read sets driveway thickness, so it has to be written into your contract. A 4 inch pad is common for walks and patios, while a driveway carrying trucks on weak soil may need more depth or steel. Ask for thickness, base, reinforcing and joint layout in the scope before you sign.
Can I pour concrete next to a parkway tree in La Mirada?
Only with care. The Municipal Code bars concrete that cuts off air, light or water to a City tree's roots, and the Director may require a barrier 5 feet outside the drip line with hand tools only inside it. A tree damaged by construction must be replaced before final inspection. Call Public Works at (562) 902-2385 before digging near one.
Who can legally do concrete work in La Mirada?
A licensed contractor, for any job of $1,000 or more with materials and always when a permit is needed, under Business and Professions Code 7048. CSLB class C-8 covers forming, placing and finishing concrete, and block walls are C-29 masonry. La Mirada also requires a City business license. Look up the license number on CSLB before signing.
