Outdoor Kitchens, Decks and Pergolas in Los Angeles and Across Southern California
Green Design and Build is a licensed general contractor (CSLB #1110975) that designs, permits and builds outdoor kitchens, decks and pergolas for homeowners across Los Angeles County and the San Fernando Valley, Orange County, Ventura County, western Riverside County and western San Bernardino County. These are the structures where the gas, the electrical and the structural inspections show up, and design-build means the layout, the engineering, the permits and the trades are all ours. For a solid roof rather than an open pergola, see patio covers; for the whole yard, start at outdoor living.
Outdoor kitchens
An outdoor kitchen in Southern California is used ten months a year, which is why it has to be built like a kitchen and not like a barbecue with a stone skirt. We build grill islands; L-shaped and U-shaped kitchens with a sink, an outdoor-rated refrigerator and a bar overhang; and full kitchens with a pizza oven, a hood under a cover, and lighting.
Gas and electrical. A built-in grill wants a dedicated natural gas line from the meter, with a shutoff and a sediment trap at the island, not a propane tank hidden in a cabinet. A refrigerator, lights and outlets need a dedicated GFCI-protected circuit. Both always need a permit and an inspection, in every city we work in; our licensed plumber runs the gas, our licensed electrician runs the circuit, and we pull the permits. See plumbing and electrical.
Frame. Steel-stud framing with cement board is light, fast and does not crack; it is our default. CMU block on a footing is right when the island doubles as a low wall or carries heavy stone veneer. A wood-framed island, which grill manufacturers’ instructions do not allow next to a burner without an insulated jacket, is the one we are still asked to replace every year.
Counters, sink, refrigerator. Poured concrete can be cast around the appliances; it needs sealing and will hairline-craze, which most owners accept. Granite takes heat and ignores sun; pick a darker slab. Porcelain slab is heat-proof and UV-stable and needs a fabricator who has cut it before. A sink drain has to go somewhere legal: the house sewer through a trap and vent, which is a plumbing permit, or a dry well where the city allows it. The refrigerator must be outdoor-rated; an indoor unit in a 100-degree Valley afternoon lasts a season.
Clearances. Grill manufacturers specify clearance to combustibles beside and above the grill, and the inspector reads the manual. A grill under a solid cover needs a vent hood, or a cover of non-combustible materials with open sides. We fix the kitchen’s position before anything else, because moving a gas stub later is the most expensive change on the job.
Decks
Most of our service area is slab-on-grade, so a deck is usually the answer for a sloped or hillside lot, or a raised-foundation house with a door 3 feet above the yard. On a flat lot at grade, pavers are usually the better choice, and we will say so.
Composite or redwood. Capped composite costs more per foot and does not need staining, splinter or check in the sun; it gets hot in dark colors and is heavier, so joists go closer together. Redwood is cooler underfoot and cheaper; it needs a finish every couple of years and will gray and crack if you skip it. The frame is pressure-treated lumber either way, with joist tops taped under composite.
Ledger or freestanding. An attached deck hangs on a ledger bolted through the rim joist, flashed above and behind, with lateral-load connectors tying it to the house framing. This is the detail the inspector spends the most time on, because a rotted ledger is how decks collapse, and on a stucco house the stucco is cut back and reflashed. A freestanding deck sits on its own posts a few inches off the wall; it costs a little more in footings, avoids opening the wall, and on a house with questionable framing it is what we recommend.
Footings. Frost is not the issue here; expansive clay and sloped grade are. Each post gets a poured footing sized to the soil and the load, with a metal post base holding the wood above the concrete. On hillside lots the engineer calls for deeper piers and sometimes a grade beam.
Height and permits. In the City of Los Angeles, the building code (LAMC 91.106.2) exempts platforms not more than 30 inches above grade from a building permit; anything higher needs a permit, engineered footings and a 42-inch guardrail. The California Residential Code that most other cities in our service area adopt is narrower: a deck is exempt only if it is under 200 square feet, not more than 30 inches above grade, not attached to the house and not serving an exit door. So a low attached deck in Orange or Ventura County can still need a permit, and a hillside lot is reviewed regardless. We confirm for the address.
Pergolas
An attached pergola ties to the house at a ledger and needs two posts instead of four; a freestanding one can go anywhere, over a kitchen or a spa, and needs four footings and a stiffer frame because nothing braces it.
Cedar, redwood or Douglas fir needs a stain every two to three years and posts kept off the concrete on standoff bases. Aluminum, either Alumawood-style lattice or a louvered system, needs no maintenance and comes in a wood-look finish that reads convincingly from ten feet. Louvered pergolas with motorized slats are the premium tier: shade when you want it, a rain-tight roof when you close them, and a circuit and permit to go with it.
A detached pergola of 120 square feet or less is usually exempt from a building permit; anything larger, and any pergola attached to the house, needs one. Lights, a fan or a motor need an electrical permit regardless. Cities differ and we confirm for the address.
How these projects fail
- A grill under a cover with no ventilation. Soot on the ceiling within a year, then heat damage to the framing. A hood, a non-combustible cover or an open bay solves it at the design stage.
- Ledger rot. No flashing, or lag screws into stucco with nothing behind them. The deck looks fine from above and is held on by paint.
- Undersized footings. A pergola post on a paver, or a deck post on a pre-cast pier on clay. The structure racks the first winter the soil moves.
- No gas shutoff at the island. The only valve is at the meter. A shutoff and a sediment trap at the appliance is cheap and required.
Where these fit in the yard
These are the last things built and the first things planned. The gas line, the drain and the conduit for the kitchen are trenched before the pavers or slab go down, and footings for a pergola or deck are poured before the base is compacted, so their footprints are decided before the hardscape is. Our order is grade and drainage, rough utilities and sleeves, footings, base and compaction, surfaces, then structures and finishes. The whole-yard budget is in our backyard remodel cost guide.
Where we build
In Los Angeles County and the San Fernando Valley, most kitchens go on slab lots with the panel on the far side of the house, so the electrical run is often the swing item, and hillside decks get engineered piers. In Orange County, a kitchen or pergola in Irvine or Yorba Linda goes through HOA architectural review before the city permit, and we prepare that package. In Ventura County, from Thousand Oaks and Simi Valley to Camarillo, wind on open lots means we brace freestanding pergolas harder. In western Riverside County, Corona, Riverside and Murrieta lots are larger and summer heat is the design driver, so shade over the kitchen earns its cost. In western San Bernardino County, Ontario, Rancho Cucamonga and Upland, the afternoon wind off the Cajon Pass decides which way the kitchen faces. Full list on our service areas page.
What they cost in Southern California
Outdoor kitchens are priced by tier, because appliances and utility runs matter more than the length of the island.
| Outdoor kitchen tier | What it includes | Typical Southern California installed range |
|---|---|---|
| Grill island | 6–8 ft steel-stud island, built-in gas grill, side burner, storage door, concrete or granite counter, gas line and permit | $6,000–$16,000 |
| Kitchen with sink and refrigerator | 10–14 ft L-shape, grill, burner, sink with drain, outdoor refrigerator, dedicated circuit, gas line, both permits | $13,000–$35,000 |
| Full kitchen with pizza oven, bar and cover | U-shape or two runs, premium grill, pizza oven, sink, refrigerator, bar overhang, lighting, and a cover with a hood | $40,000–$85,000+ |
These are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.
Line items and worked examples are in our outdoor kitchen cost guide. Decks are priced per square foot, footings and framing included.
| Deck type | Typical Southern California installed range, per sq ft |
|---|---|
| Redwood decking on pressure-treated frame, at grade | $35–$60 |
| Composite decking on pressure-treated frame, at grade | $45–$75 |
| Raised deck over 30 in with 42 in guard and stair, redwood | $50–$80 |
| Raised deck over 30 in with guard and stair, composite | $60–$95 |
These are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.
Pergolas are priced per square foot of roof area and depend on material more than size; the figures are in our pergola cost guide.
Frequently asked questions
Do I need a permit for an outdoor kitchen in Los Angeles?
Yes, for the gas line and the electrical circuit, in every city in our service area, and for a sink drain tied to the sewer. The island itself is usually below the threshold for a building permit unless it is a tall block structure or carries a roof. A new cover over the kitchen needs its own building permit. We pull all of them and schedule the inspections.
How high can a deck be before it needs a permit?
In the City of Los Angeles, a platform not more than 30 inches above grade is exempt from a building permit under LAMC 91.106.2. Above that, you need a permit, engineered footings and a 42-inch guard. Most other cities use the state residential code, which also requires the deck to be detached, under 200 square feet and not serving an exit door. Hillside lots are reviewed regardless.
Is composite decking worth the extra cost over redwood?
If nobody in the house will stain a deck every two years, yes. Composite costs roughly a third more installed and then costs nothing for a decade or more. Redwood is cooler underfoot, cheaper and better looking the day it is finished, but a neglected redwood deck in Valley sun grays and checks within a few summers. On a west-facing deck, pick a light composite color; dark boards get too hot for bare feet.
Can I put a grill under a patio cover?
Only with the right design. A gas grill under a solid cover needs a vent hood rated for outdoor use, or a cover built of non-combustible materials with open sides, and the manufacturer’s clearance above the cooking surface has to be met. An open pergola is usually fine. Ignoring this is the most common failure we inspect: soot on the ceiling, then heat damage to the framing.
Which is cheaper, a pergola or a solid patio cover?
An aluminum lattice pergola is the least expensive at about $25 to $45 per square foot installed; a solid aluminum cover runs $30 to $55 and a wood cover $40 to $80. Louvered motorized pergolas cost more than most solid covers. These are typical Los Angeles budgeting estimates, not a price list or a quote. Your project can come in lower or higher depending on the house, the scope and the finishes; the only real number is a written proposal after a site visit.
How long does an outdoor kitchen take to build?
Plan on four to eight weeks from permit to first cookout for a kitchen with a sink and refrigerator: a week for trenching, rough-in and inspection, a week for the frame, a week or two for counters and finish, then appliance set, final inspection and gas tie-in. A grill island is faster. Appliance lead times are the usual delay, so we order them before we break ground.
Start with a site visit
The right kitchen, deck or pergola depends on where the gas meter and panel are and how the yard drains. The site visit is free, takes about two hours, and you will have a written proposal within 48 hours with the permits, the utility runs and the structure listed separately.
