How Much Does a Pergola Cost in Los Angeles?

A pergola in Los Angeles usually costs $2,500 to $6,500 installed for a 10×10 in aluminum lattice or wood, $5,000 to $12,500 for a 12×16, and $7,000 to $18,000 for a 14×20, footings included. A louvered motorized pergola is a different budget: $6,000 to $13,000 for a 10×10 and $17,000 to $36,000 for a 14×20. Material sets the per-square-foot rate, size multiplies it, and the permit, the electrical and what the posts land on decide the rest.

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.

For how we build them, see outdoor kitchens, decks and pergolas. We build pergolas across Los Angeles County and the San Fernando Valley, Orange County, Ventura County, western Riverside County and western San Bernardino County.

Cost by material

Pergolas are priced by the square foot of roof area. The ranges include posts, beams, lattice or rafters, footings and installation, and exclude electrical, permits and any new slab.

Material	Typical Los Angeles installed range, per sq ft	What you are paying for
Vinyl kit	$20–$40	Low maintenance, limited sizes and spans, hollow posts that need reinforcing
Aluminum lattice, Alumawood style	$25–$45	Embossed wood-look finish, no maintenance, long spans; the most common shade structure in our area
Wood, cedar or redwood, custom built	$35–$65	Real timber, any size or profile, stain every two to three years
Steel, custom	$60–$110	Thin profiles over long spans, welded on site, primed and painted
Louvered aluminum, manual	$45–$110	Adjustable slats that close for rain, integrated gutters
Louvered aluminum, motorized	$60–$130	Motor, rain sensor, lighting options, a circuit and an electrical permit

Aluminum lattice is the value choice and what most of our clients end up with; vinyl kits flex in wind unless the posts are sleeved over steel.

Cost by size

Size	Vinyl kit	Aluminum lattice	Wood	Steel	Louvered motorized
10×10 (100 sq ft)	$2,000–$4,000	$2,500–$4,500	$3,500–$6,500	$6,000–$11,000	$6,000–$13,000
12×16 (192 sq ft)	$3,800–$7,700	$4,800–$8,600	$6,700–$12,500	$11,500–$21,100	$11,500–$25,000
14×20 (280 sq ft)	$5,600–$11,200	$7,000–$12,600	$9,800–$18,200	$16,800–$30,800	$17,000–$36,000

A 12×16 is 192 square feet, over the 120 square foot exemption, so the jump from a 10×10 to a 12×16 is usually also the jump from no permit to a permit.

Attached or freestanding

An attached pergola bolts to a ledger on the house and needs two posts instead of four, but on a stucco house the ledger means cutting the stucco, flashing and patching, and an attached structure always needs a building permit. A freestanding pergola needs four footings and knee braces because nothing else holds it square, and it can go anywhere, including over an outdoor kitchen. On our jobs the price difference is small; decide by where you want the shade and whether you want to open the wall.

Louvered and motorized pergolas

A louvered pergola is an aluminum frame with rotating slats: open, it is a pergola; closed, it is a rain-tight roof that drains through the beams into gutters and down the posts. Motorized systems add a motor, a remote and usually a rain sensor, and the motor needs a dedicated circuit and an electrical permit. They cost two to three times what aluminum lattice costs. For a covered outdoor kitchen or a west-facing patio in Corona or Rancho Cucamonga, the adjustability is worth it; for a shaded corner in a coastal yard it usually is not, and we will say so. Two contractor notes: the frame has to be dead level or the louvers will not seal, and the gutters need somewhere to drain; a downspout dumping onto pavers next to the house is a drainage problem you paid extra for.

Footings and what the posts land on

Every post on our jobs lands on a poured concrete footing sized for the soil and the uplift, with a metal post base holding wood off the concrete; in Valley clay and on hillsides the footing goes deeper. A pergola on surface brackets over pavers is the structure that racks in the first Santa Ana wind. On an existing slab, we core through it and pour footings below; the slab is not the footing. If the patio is built at the same time, the footings go in before the base is compacted, and the new surface is priced separately; see pavers and our paver patio cost guide.

Permits

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, with a plan showing the footings, connections and setbacks. Lights, a fan or a louver motor need an electrical permit regardless of size. An HOA in Orange County wants the color, height and material approved before the city sees the plan. Thresholds vary by city; we confirm for your address.

Pergola or solid patio cover

A pergola gives partial shade and a ceiling line; a solid cover gives full shade, rain protection and a place to mount a fan and lights. The prices overlap: an Alumawood lattice cover runs $25 to $45 per square foot, a solid Alumawood cover $30 to $55, an insulated cover $45 to $75, a wood cover $40 to $80 and a steel cover $60 to $110. A louvered pergola costs 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.

Our rule of thumb: if you want to sit under it in August at 3 PM, or eat under it when it rains, you want a solid or louvered roof; if you want dappled light and a vine in five years, you want a pergola. The full comparison is in our patio cover cost guide and our patio cover design ideas.

Frequently asked questions

How much does a 10×10 pergola cost installed?

A 10×10 pergola typically costs $2,000 to $4,000 as a vinyl kit, $2,500 to $4,500 in aluminum lattice, $3,500 to $6,500 in cedar or redwood, and $6,000 to $13,000 as a motorized louvered system, footings included. 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.

Do I need a permit for a pergola in Los Angeles?

A detached pergola of 120 square feet or less is usually exempt from a building permit. A larger one, or any pergola attached to the house, needs a permit with a plan showing the footings and connections. Lights, a fan or a louver motor need an electrical permit no matter how small the structure. Cities and HOAs differ, so we confirm for your address before the proposal.

Is a louvered pergola worth the extra cost?

For a covered outdoor kitchen, a west-facing patio, or an inland yard where you want shade in July and a dry table in January, usually yes; it replaces both a pergola and a solid cover. For a shaded corner in a mild coastal yard, an aluminum lattice pergola at a third of the price does the job. We will tell you which one your yard is.

Which is cheaper, a pergola or a patio cover?

An aluminum lattice pergola is the least expensive shade structure, and a solid aluminum cover is close behind; wood and steel covers cost more per square foot, and a louvered pergola costs more than most solid covers. If you want full shade and rain protection, the solid cover is the better value; if you want dappled light, the pergola is. The figures are in the section above.

Can a pergola be installed on an existing patio?

Yes, but the slab or the pavers are not the footing. We core through the surface and pour a concrete footing under each post, then patch around the post base; pavers make this nearly invisible. Surface-mounted brackets on a thin slab let a pergola rack in the first strong wind, and we do not install them that way.

How long does a pergola take to install?

An aluminum lattice or vinyl kit goes up in one to two days after the footings cure, so plan on about a week from the first dig. A custom wood or steel pergola takes one to two weeks. A permitted pergola adds a few weeks for plan check and a footing inspection, and a louvered system can be several weeks from order to delivery.
