What does a Bay Area deck cost?

Permitted single-level decks $100–$220 per sq ft, depending on height, structural engineering, and material.

Do you do hillside decks?

Yes — engineered drilled piers and lateral bracing for East Bay and Peninsula hillside lots.

SB-326 inspection support?

Yes — we provide SB-326 inspection (when paired with remediation contract) and the remediation construction itself.

How long does a Bay Area deck build take?

Most permitted single-level decks build in 4–7 weeks on site after permit. Hillside decks with engineered drilled-pier footings run 7–11 weeks.

What deck material lasts longest in the Bay climate?

Ipe, thermally modified hardwoods, and capped composites handle the Bay's wet-dry cycle best. Pressure-treated is shortest-lived and we only use it when budget demands and structure (not finish) is the priority.

Bay Area Deck & Outdoor Living Contractor. the deck SB-326 wants you to build right.

Bay Area decks live in a particular climate: wet winters, dry summers, and the SB-326 inspection regime for any deck on a multi-family building. We build permitted decks, pergolas, and outdoor living across the East Bay, Peninsula, South Bay, and SF — hillside engineered decks in Berkeley and Oakland, level decks on Peninsula ranches, roof decks on SF flats.

Every deck we build connects to the house with a proper ledger detail (through-bolt, flashing, drainage gap) — not surface lag screws waiting to leak and rot.

Bay Area permit notes · Decks & Outdoor

What we resolve before drawings begin.

01
City permit over 30" or attached to house
Each Bay city pulls deck permits at slightly different thresholds. We pull what's required, with structural drawings on engineered builds.
02
Hillside footings + drainage
Bay hillside decks need engineered footings (drilled pier or caisson), lateral bracing, and surface drainage. Structural engineer always.
03
Material selection for wet winters
Ipe, thermally modified wood, or composite — selected for the Bay's wet-dry cycle. Pressure-treated only when budget demands and detail allows.

Decking intel · composites vs. hardwood · Bay Area 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.

5 brands · ordered by frequency on jobs

Trex
premium
Winchester, VA · invented modern composite decking in 1996
Transcend, Enhance, Signature lines

TimberTech (AZEK)
premium
Skokie, IL
AZEK PVC (Vintage, Harvest) and Pro composite lines

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.
