What does an LA permitted deck cost?

Most LA permitted single-level decks land $80–$180 per sq ft, depending on height, structural engineering, and material (Ipe / composite / pressure-treated).

Do you do hillside decks?

Yes — engineered footings, caissons, and structural review for LA hillside lots are routine work for our crew.

Can you add a pergola or patio cover?

Yes — attached and detached pergolas / patio covers, with optional motorized louver systems and integrated lighting.

How long does an LA deck build take?

Most permitted single-level decks build in 3–6 weeks on site after permit. Hillside decks with engineered footings run 6–10 weeks.

What material lasts longest in the LA climate?

Ipe and thermally modified hardwoods carry the best long-term performance under LA's UV exposure. Capped composites are a strong second; pressure-treated is shortest-lived.

Most of our LA deck work involves hillside posts, footing engineering, and a real connection back to the house — not surface-fastened ledger boards waiting to fail.

Los Angeles permit notes · Decks & Outdoor

What we resolve before drawings begin.

01
LADBS permits over 30 inches or attached to house
Decks more than 30" off grade, or attached to the house, require LADBS permits with structural drawings and inspections. We pull them.
02
Hillside footings and lateral
Hillside decks need engineered footings (often caissons), lateral bracing, and slope-stability review. We commission the structural engineer at feasibility.
03
Ledger connection detail
The most common deck failure mode is a ledger pulling away from the house. We use through-bolts with proper flashing, not lag screws into stucco.

Decking intel · composites vs. hardwood · Los Angeles spec

Composite deck boards have closed 90% of the appearance gap with hardwood while erasing the annual sand-and-seal cycle. The remaining 10% is what you pay for.

The manufacturers we actually specify.

Material tiers · what you're actually choosing between.

CA installed pricing · 2025

Material	Lifespan	Installed in CA	Best for	Trade-offs
Composite (Trex / TimberTech Pro)	25–30 years	$45–$70 / sq ft	Most LA backyard decks.	Surface temperature 30°F hotter than wood in direct sun — pick light colors for shoeless areas.
Capped PVC (AZEK Vintage)	30–50 years	$55–$85 / sq ft	Pool decks, oceanfront, shaded wet decks.	Sound (drum-like) under boards — specify hidden fasteners and 16-in joist spacing.
IPE hardwood	30–50 years	$60–$100 / sq ft	Architectural decks; modern + Japanese minimalism.	Requires pre-drilling for every screw; oil annually or accept silver patina.
Pressure-treated pine	10–15 years	$25–$40 / sq ft	Sub-structure / hidden framing.	We rarely use as the surface deck — sun cycle destroys it on schedule.

Specification gotchas we resolve before contract.

01
Joist spacing per the manufacturer.
Trex Transcend allows 16-in OC parallel, 12-in OC on a 45° pattern. Get this wrong and you void the warranty and the boards sag in 18 months.
02
Ledger flashing detail.
We install Z-flashing + butyl tape behind the ledger and weep at every joist hanger. Code requires it; most decks under 10 years old don't have it.
03
Title 24 compliance for raised decks.
Decks over 30 inches require guard rails ≥ 42 in with ≤ 4-inch sphere openings. Cable rail systems must use marine-grade SS316 in coastal zones.
