Concrete Companyin Downey, CA
A concrete company in Downey can usually pour a patio or walk on a flat lot, but the City's own pages disagree on which flatwork is exempt, and the driveway apron, curb and sidewalk need a separate Public Works permit. Retaining walls over 4 feet need a permit. Front yard paving has caps, so ask Planning first.
Downey is flat, and its concrete is old. The median Downey house went up in 1959, which makes the average driveway, walk and patio slab close to seven decades old, and the Housing Element says the city's oldest sewers date from 1927 with most of the system built between 1945 and 1955. The land was Rancho Santa Gertrudes and then citrus country before tract builders poured thousands of slabs, and the city incorporated in 1956 as the 50th in Los Angeles County.
MDG Builders, CSLB #1040337, is a general contractor in Tarzana. We measure the site, ask Downey Building & Safety and Public Works what applies, and book the work, while a licensed concrete subcontractor forms and pours it. You can ask for that firm's license number and proof of insurance. Prices and materials are on our concrete page, and the Downey overview lists our other trades here.
What Downey's City pages say about concrete work
Where concrete permits come from in Downey: City of Downey Community Development Department, Building & Safety Division.
- Planning's R-1 development standards brochure (undated, scanned) allows one driveway per single-family parcel, caps the front yard hardscape at 50 percent on lots narrower than 60 feet and 40 percent on lots 60 feet or wider, requires at least two feet of landscaping between a parallel driveway and walkway, and lists Portland cement concrete, stamped or colored concrete, brick, pavers or comparable approved materials for driveways. The text comes from an optical scan, so confirm the numbers with Planning.
- The Public Works permit list covers drive approaches, sidewalks, ramps and curb and gutter in the right-of-way with a separate permit for which contractors need a Class A or C-8 license, a City business license and approved insurance. Required general liability insurance is $2,000,000 per occurrence for contractors and $200,000 per occurrence for homeowners, with the City named as additional insured.
- The Division's FAQ exempts cut and fill under 50 cubic yards on natural terrain flatter than 5:1 or less than three feet deep that does not obstruct drainage, and requires a permit for grading over 50 cubic yards or work that affects site drainage. Retaining walls up to four feet from the bottom of the footing are exempt unless they support a surcharge or impound Class I, II or IIIA liquids.
- Section 9520.04 requires all front and street side setbacks to be landscaped except approved walkways and driveways, and says trees in the parkway are planted as Public Works requires while the property owner maintains parkway trees and landscaping.
- Table 9.3.3 in the zoning code caps walkway width at 6 feet in the R-1 zone.
Does Downey's liquefaction zone change how a slab, footing or walkway is built?
The State maps all of Downey as a liquefaction zone, according to the City's Housing Element, and Los Angeles County's hazard layer put all 31 sample points we checked inside it. A small concrete walk is not designed around that map, but footings, tall walls and anything holding up a roof are. The Housing Element says the City requires geotechnical reports for construction projects.
The same document calls Downey predominantly flat, with no Alquist-Priolo fault traces and no identified landslide areas. Flat ground drains slowly, so a new patio can steer water toward the house or a neighbor as easily as away from them. A good bid shows the intended slope and where the runoff ends up.
Before any old slab is broken out, ask about buried lines. With most of the sewer system laid between 1945 and 1955, older lateral pipes may sit under a driveway or side yard, and a camera inspection before demolition costs less than a crushed pipe. The City's soils report handout, dated 2017, also asks for a report on retaining walls over 3 feet.
- Who looked at drainage, and where will the water go?
- Are sewer or irrigation lines marked before demolition?
- Is a soils report expected for this wall or footing?
How much of a Downey front yard can be paved, and can a driveway be widened?
Less than most owners expect, and the numbers come from a scanned document. Planning's single-family development standards brochure is undated and was read from an optical scan, so confirm it with Planning. It allows one driveway per parcel, caps front yard hardscape at 50 percent on lots narrower than 60 feet and at 40 percent on lots 60 feet or wider, and asks for at least 2 feet of landscaping between a parallel driveway and walkway.
The zoning code backs the landscaping idea. Section 9520.04, which the City publishes on ecode360, requires front and street side setbacks to be landscaped except for approved walkways and driveways. Table 9.3.3 limits an R-1 walkway to 6 feet wide. The brochure lists Portland cement concrete, stamped or colored concrete, brick and pavers as acceptable driveway surfaces.
A wider driveway, a second drive or a parking pad in the front yard is therefore a Planning question before it is a concrete question. Planning's Development Standards page says fences, gates, paving, driveways and small accessory structures can be approved over the counter with a plot plan, with flat fees for single-family lots. Bring the plot plan and ask for the percentage in writing.
Who permits a driveway apron, sidewalk or curb in Downey, and what insurance is required?
Public Works does, and it is a separate permit from anything on your own lot. The City's permit list names drive approaches, sidewalks, ramps and curb and gutter work in the public right-of-way, each with contractor license, City business license and insurance conditions. Public Works moved to the Accela portal on June 1, 2026, and questions go to publicworks-engineering@downeyca.org.
The contractor must hold a Class A or C-8 license. Required general liability insurance is $2,000,000 per occurrence for contractors and $200,000 per occurrence for homeowners, with the City named as additional insured. So an owner can pour a driveway on their own, but the owner needs a certificate to match, and a contractor's certificate has to name the City.
Parkway trees follow Public Works rules, and the owner maintains them, so roots that lift a sidewalk panel are the owner's problem to raise with the City before any panel is replaced. A dumpster parked in the street also needs an encroachment permit. Plan the apron, the curb and the debris container before the first sawcut, not after.
Block walls and retaining walls: what height needs a permit in Downey?
Four feet is the figure on the Building Division's FAQ for retaining walls, measured from the bottom of the footing, and the exemption ends if the wall carries a surcharge or certain liquids. A block wall of 42 inches or less needs no building permit but still needs Planning approval, and anything over 42 inches needs a Building permit too. The City's own pages conflict on fence height, since the zoning code says 7 feet on interior lines and an older Planning sheet says 6, so ask which controls.
The City's block wall standard covers garden and site walls under 7 feet and calls for a plot plan, footings at least 16 inches into natural soil, widths from 18 to 36 inches by wall height, and inspections for footing and steel, pre-grout and final after the cap. A Common Wall Agreement is needed on or beside a shared line. Retaining walls cannot use that standard.
Block is C-29 masonry, and a poured wall is C-8 concrete; ask each bidder which license the sub holds. Walls facing the street need anti-graffiti coating under Section 9520.08, and front yard walls are held to 42 inches. Our subcontractor explainer shows what to request from the sub.
Can you pour concrete work in Downey's heat and rain, and what hours may the crew work?
Yes, with planning. NOAA's 1991 to 2020 normals for Long Beach Daugherty Field show 12.02 inches of rain a year, about 81 percent of it from December through March, and about 23 days at or above 90 degrees. A pour is usually booked in a dry stretch, and in a hot week the crew starts early and keeps the surface damp while it cures.
Ask how the contractor protects fresh concrete from a sudden shower and how long the forms stay on. The City limits private construction to 7:00 a.m. to 7:00 p.m. Monday through Saturday and bans Sunday and Federal holiday work within 500 feet of a home. Section 4606 also sets an 85 decibel cap for other construction.
The County's dam inundation layer lists the Whittier Narrows Dam reservoir over every sample point, and the Housing Element says no property is in a FEMA 100-year flood zone since the levees were raised in 2000. The dam point is a County mapping finding, not a City statement, and it does not change how a patio is poured. It is one more reason to keep runoff off neighboring lots.
What does concrete work cost in Downey for a patio, walk or driveway?
We found no Downey price study with a stated method, so these figures are Los Angeles ones. A plain broom-finished patio, walk or slab of 300 square feet or more runs about $8 to $14 per square foot, from Angi's Los Angeles patio page and HomeGuide, which overlap at $4 to $13. A 400 square foot patio would multiply to roughly $3,200 to $5,600 before extras. Small jobs usually price higher because of minimum charges.
Stained, stamped or exposed aggregate surfaces start near $15 and reach about $30 a square foot, and replacing a driveway with the old slab hauled away runs roughly $9 to $20. We rate those figures medium to low in confidence. The Bureau of Labor Statistics put the mean wage for cement masons in the Los Angeles-Long Beach-Anaheim area at $33.67 an hour in May 2025.
Demolition, base repair, rebar, drainage, the curb permit and the City business license are separate lines. See our concrete page for the sources, and the license check guide for how to confirm a C-8 number.

Downey concrete questions, answered
Can I pour a concrete patio without a permit in Downey?
Possibly, but the City's pages do not give one clear answer. The Building Division's exempt list names sidewalks and driveways under 800 square feet that keep their grade and purpose, yet the City also says hardscapes generally need a permit. Call the Building counter at (562) 904-7142 with the size and location before ordering concrete, and ask Planning about front yard limits.
Can I expand my driveway without a permit in Downey?
Not safely. Planning's scanned brochure allows one driveway per parcel and caps front yard hardscape at 50 or 40 percent depending on lot width, and the apron at the curb needs a Public Works permit. Confirm the numbers with Planning because the brochure is undated, and expect a plot plan to be requested.
Are you allowed to pour your own driveway in Downey?
Yes, an owner can apply, but conditions apply. A building permit can go to an owner-builder living in the single-family house, and Public Works requires $200,000 per occurrence of liability insurance for homeowners, with the City as additional insured. The approach, curb and sidewalk need their own permit, and a contractor needs a Class A or C-8 license.
What is the maximum height of a retaining wall without a permit in Downey?
Four feet, measured from the bottom of the footing to the top, according to the Building Division's FAQ, and only if the wall does not support a surcharge or certain liquids. The City's soils report handout, dated 2017, asks for a report on retaining walls over 3 feet, so ask plan check how the two lines fit together before digging.
How tall can a block wall be on my Downey property line?
The zoning code says 7 feet on interior side and rear lines and 42 inches in the front and street side setback, while an older Planning sheet says 6 feet. A block wall over 42 inches needs a Building permit, and one on a shared line needs a Common Wall Agreement. Ask Planning which interior height controls.
How much should a 20x20 concrete patio cost in Downey?
About $3,200 to $5,600 for a plain broom finish, found by multiplying 400 square feet by the Los Angeles range of $8 to $14 per square foot, and roughly $6,000 to $12,000 for a stamped or stained surface at $15 to $30. These are medium to low confidence ranges, not a quote, and a small slab can price above the per-foot average.
How much does a concrete driveway replacement cost in Downey?
Roughly $9 to $20 per square foot in the Los Angeles sources we use, with the old slab demolished and hauled away. A two-car driveway of 400 square feet would multiply to about $3,600 to $8,000. Base repair, the Public Works apron permit, drainage fixes and sewer line checks are extra, and a site visit sets the price.
Is stamped concrete cheaper than pavers in Downey?
We cannot say from sourced data, because we found no independent Downey comparison and no sourced paver price. Stamped or stained concrete runs about $15 to $30 per square foot in Los Angeles sources. Planning's brochure accepts either surface for driveways, so the choice rests on drainage, repair access, cracking and what the front yard cap allows.
What license does a concrete company need in Downey?
A C-8 concrete license covers forming, pouring and finishing, and C-29 covers concrete block walls, unless the job costs $1,000 or less and needs no permit. Public Works requires a Class A or C-8 license for curb, sidewalk and approach work, plus a City business license and insurance naming the City. Check the number on the CSLB site.
How wide can a walkway be in a Downey R-1 zone?
Table 9.3.3 in Downey's zoning code caps a walkway at 6 feet wide in the R-1 zone, and the code requires front and street side setbacks to stay landscaped except for approved walks and driveways. Ask Planning about a path that doubles as a patio, since a wide slab can read as hardscape against the front yard cap.
