Concrete Companyin South Pasadena, CA
A concrete company in South Pasadena works around older rules than most: the City's guidelines keep historic driveways where they are with no new curb cuts, hillside lots cap retaining walls at 6 feet, and a lifted slab rarely justifies removing a protected tree. Flatwork looks permit-exempt, but confirm it.
Concrete here is old. The City's 2021 guidelines describe the Arroyo Seco as a fording place for the Tongva and Kizh people, with the first adobes on Rancho San Pasqual built on the South Pasadena side, and the city incorporated in 1888. Census estimates for 2020 to 2024 count 3,574 of 10,817 homes (33.0 percent) built in 1939 or earlier, so an original front walk, driveway strip or garden step may be 87 years old or more. Single-family detached homes number 4,801, about 44 percent of the stock.
MDG Builders, CSLB #1040337, is a Tarzana general contractor, which means we scope the job, ask the Building Division what applies and bring in a licensed concrete or masonry subcontractor to form and pour. The concrete page covers finishes and materials, and the South Pasadena overview lists the other trades we handle here.
What South Pasadena's Building Division, Planning Division and Municipal Code say about concrete work
Where concrete permits come from in South Pasadena: City of South Pasadena Community Development Department, Building Division.
- The city's 2015 Southwest Monterey Hills booklet lists driveways, patios and other flat work as not needing a permit, but using the street for materials, bins or equipment needs a Public Works encroachment permit, and any construction bin must come from Athens Services under the city's exclusive agreement (as stated in that booklet).
- For driveways on historic residences, the 2009 guidelines say new curb cuts should not be added, existing driveway locations should remain, most driveways run along the side yard to a rear garage, and concrete with a pattern, texture and color that matches historic material is encouraged.
- On hillside sites the driveway ramp within 10 feet of a garage may be no steeper than 5 percent and the average finished driveway grade no more than 15 percent (36.340.050.E).
What should new concrete look like next to a South Pasadena Craftsman or Spanish house?
Like the old concrete. For driveways on historic residences, the City's 2009 Residential Design Guidelines say new curb cuts should not be added and existing driveway locations should stay, with most driveways running along the side yard to a rear garage. Concrete whose pattern, texture and color match the historic material is encouraged, so ask Planning whether a stamped or tinted finish suits the house before anyone orders it.
Front yards get their own advice. The same guidelines discourage large areas of paving in front yards and say historic retaining walls, curbs and stairs should be preserved, which makes a cracked original step a repair question before it is a demolition question.
Review can follow. Design review under Zoning Code 36.410.040 reaches exterior construction that needs a building permit, and the Planning Division says Cultural Heritage Commission approval is required for changes to listed properties. The Inventory of Cultural Resources lists 2,718 properties and district contributors, so check whether the address is on it. The Inventory also names districts such as Oaklawn, Garfield Park and Ramona Craftsman, although it mixes designated and potential districts, so the Planning Division is the place to confirm a boundary.
Do you need a permit to pour a driveway, patio or walk in South Pasadena?
For the slab alone, probably not, but the City's own code was out of reach for us. Its publisher blocked automated access, so we read a GoCodebook mirror, and the only City document we found that names flatwork is the 2015 Southwest Monterey Hills booklet, which lists driveways, patios and other flat work as not needing a permit. It is a handout for one hillside area, so confirm the line with the Building Division.
Zoning is a separate gate. A Planning Clearance (36.410.020) is required when a structure is erected or remodeled and is filed with the building permit application. A slab with a footing, a wall or a roof over it is more than flatwork.
The street is a different permit. Using the public street for materials, bins or equipment needs a Public Works encroachment permit. For work on a sidewalk or driveway apron, ask Public Works too, because we found no South Pasadena text on aprons.
- Is the work flat, with no wall, footing or roof?
- Does anything touch the public sidewalk, curb or apron?
- Is the house on the Inventory of Cultural Resources?
How tall can a retaining wall be in South Pasadena before it needs a permit?
The City's own papers disagree. The 2015 Southwest Monterey Hills booklet lists retaining walls higher than 3 feet as permit work, while the exempt list on the code mirror says walls of 4 feet or less, measured from the bottom of the footing, are exempt unless they carry a surcharge. Until the Building Division says which governs your lot, plan for the lower number and keep the footing depth on the drawings.
Block is a separate question. Zoning Code 36.300.050 bars concrete masonry units as fence material unless Design Review approves them, and screening walls under 36.300.070 need Design Review too. The mirror exempts masonry or concrete fences of 6 feet or less from a building permit, but zoning still applies.
CSLB describes the C-8 class as work that forms, pours, places and finishes concrete, and its C-29 class covers concrete block walls for structures and fences. Ask the subcontractor which license fits your wall.
What changes for concrete on a hillside lot in South Pasadena?
A lot with an average slope of 20 percent or more falls under Division 36.340, which brings a Hillside Development Permit, Design Review and a preliminary geotechnical report. Retaining walls there may not exceed 6 feet, long walls should be terraced or offset about every 30 feet, and walls over 3 feet that can be seen from off the site should be screened with landscaping.
Driveways carry numbers too. Within 10 feet of the garage the ramp may be no steeper than 5 percent, and the average finished driveway grade may be no more than 15 percent (36.340.050.E). On a steep lot those two limits decide where a driveway can run before anyone picks a finish.
The Altos de Monterey overlay adds its own caps, among them 40 percent lot coverage and fences of 3 feet in front setbacks, and its retaining walls top out at 6 feet with walls spaced a distance equal to their height apart. Ask Planning whether new paving counts toward the 40 percent.
How do pour trucks, bins and work hours work on South Pasadena streets?
A pour follows the City's construction hours: 8:00 a.m. to 7:00 p.m. on weekdays, 9:00 a.m. to 7:00 p.m. on Saturday and 10:00 a.m. to 6:00 p.m. on Sundays and recognized holidays. Heat shapes the start time: NOAA's normals for the Pasadena station show 74.1 days a year above 90 F and 9.5 above 100 F, so ask how the crew will cure a slab on a hot afternoon.
The Southwest Monterey Hills have tighter rules. The 2015 booklet requires a Hillside Construction Staging Plan for grading, demolition, excavation and caisson work, plus a deputy inspector with an initial $12,000 deposit (a 2015 figure), and it limits construction vehicles to 48,000 pounds gross and the street to 8:30 a.m. through 2:00 p.m. A loaded mixer is a heavy vehicle and we found no sentence naming mixers or pumps, so ask before a pour is scheduled.
Broken driveway needs a place to go: the booklet says a construction bin must come from Athens Services under the City's exclusive agreement.
Can you remove a tree whose roots lifted your concrete in South Pasadena?
Probably not for that reason alone. The City's tree page says Public Works must issue a permit before any pruning of protected trees and that removal needs a substantial reason, with limb or root problems typically not qualifying. Replacement trees must be planted within 90 days, and a denied removal can be appealed to the Natural Resources and Environmental Commission. Contact is publicworkspermits@southpasadenaca.gov or (626) 403-7240.
Chapter 34 (Ordinance 2409 of 2025) protects oaks, California bay laurel, sycamores, toyon, Southern California black walnut and others. Trimming more than 10 percent of a protected tree's live foliage needs a permit, so does removing a protected, significant or restricted tree of 12 inches DBH or more, and oak trimming is generally limited to June 1 through September 30.
Penalties can include a replacement fee of up to twice the appraised tree value, and tree penalties must be paid before building permits issue. So ask the concrete subcontractor to design around the tree, with a ground panel, a ramp or a curved walk, before anyone mentions a saw.
What does a concrete company charge for concrete work in South Pasadena, and which license applies?
No South Pasadena price study turned up, so the anchor is Angi's Los Angeles pages from 2026: patios at $4 to $13 a square foot with a $5,248 average, stamped patios at $15 to $30, driveways at $8 to $20 with a $7,270 average and retaining walls averaging $7,140. Our planning ranges for a flat, accessible 4 inch slab are $8 to $14 a square foot for patios, walks and slabs of 300 square feet or more, $15 to $30 for stained, stamped or exposed aggregate finishes and $9 to $20 for driveway replacement including demolition. Small jobs cost more per foot because of minimum charges. We print no per-foot figure for retaining walls, since drainage and engineering set the price. The federal wage survey for the Los Angeles metro shows cement masons averaging $33.67 an hour in May 2025, a wage and not a billing rate.
A license is needed for any job above the state's $1,000 minor-work limit and for any job that needs a permit, and a home improvement down payment may not exceed $1,000 or 10 percent of the price, whichever is less. Our license check guide shows how to look up a number, and our guide on how general contractors use subcontractors explains who does what on a poured job.

Other work we manage in South Pasadena
South Pasadena concrete questions, answered
Can I pour a concrete patio without a permit in South Pasadena?
Probably, if it is flat. The City's 2015 Southwest Monterey Hills booklet lists patios and other flat work as not needing a permit, but we found no other City document that names flatwork and could not read the City's own code. A Planning Clearance, a wall or a footing changes the answer, so call the Building Division before you pour.
Can I expand my driveway without a permit in South Pasadena?
Not safely. The 2015 booklet calls driveways permit-free, but the historic guidelines say new curb cuts should not be added and existing driveway locations should stay, and hillside lots cap the ramp near the garage at 5 percent. Widening can also touch the sidewalk or street, so ask the Building and Planning divisions first.
What is the maximum height of a retaining wall without a permit in South Pasadena?
It depends on the source. The City's 2015 hillside booklet says walls higher than 3 feet need a permit, while the code mirror exempts walls of 4 feet or less measured from the bottom of the footing, unless they carry a surcharge. Plan for 3 feet until the Building Division confirms, and expect 6 feet as the hillside zoning cap.
Does a 4 ft retaining wall need drainage in South Pasadena?
In practice yes, because a wall that holds soil needs a way for water to escape, but we found no South Pasadena sentence that sets the detail. Drainage and engineering are what stretch the cost range, which Angi puts at $2,674 to $11,842 in Los Angeles. Ask the subcontractor to show the drain on the drawing.
How much does a 20x20 concrete patio cost in South Pasadena?
At our planning range of $8 to $14 a square foot, 400 square feet comes to about $3,200 to $5,600 for a flat, accessible site with a 4 inch slab. Angi's Los Angeles page shows $1,600 to $5,200 for a 20 by 20 patio. Demolition, access and finish raise the number.
How much would a 20x20 stamped concrete patio cost in South Pasadena?
Stamped work runs $15 to $30 a square foot in Angi's Los Angeles pages, which puts 400 square feet at about $6,000 to $12,000. On a historic house, check that the pattern and color suit the City's guidelines before ordering, since a mismatch can mean redoing the surface at your own cost.
Is 4 inches of concrete thick enough for a driveway in South Pasadena?
Four inches is the common planning thickness for a residential driveway, but we found no code text that sets it, so treat it as industry practice. Heavy trucks, soft ground or a slope can call for more thickness or rebar, and the proposal should state thickness, base and joint spacing in writing.
Can I remove a tree that is lifting my concrete in South Pasadena?
Usually not on that ground alone. The City says removal of a protected tree needs a substantial reason and that limb or root problems typically do not qualify, and the permit comes from Public Works. A concrete contractor can often grind, ramp or rebuild the lifted panel instead, so ask for that option first.
What license does a concrete company need in South Pasadena?
Poured concrete work falls under CSLB's C-8 class and concrete block walls under C-29. Work that needs a permit must go to a licensed contractor even under $1,000. Look the number up on the CSLB site, and ask each subcontractor for a license number and certificate of insurance before a start date is set.
Tell us what is being poured and how the lot slopes
Describe the slab, walk or wall, whether the lot slopes or sits on a hillside street, and whether a tree or the public sidewalk is involved. The permit, overlay and truck questions come with us to the first visit.
