01 Why it matters
A new deck is an exterior elevated element from day one
In California, any deck raised more than six feet above grade and serving a multifamily or commercial building is an exterior elevated element (EEE) — the same class of structure governed by SB 721 and SB 326. The deck you install today enters a mandatory inspection cycle every six to nine years, and the assembly the inspector examines is the exact one your installer builds now. There is no reset.
Install it the wrong way — a framing crew here, a separate waterproofer there, a railing sub signing off on his own piece — and the seams between those trades become the first place water gets behind the membrane. Rot, delamination, and a failed inspection follow, often before the deck is a decade old.
A professional deck installation built as one integrated system is the difference between a deck that clears inspection untouched and one that drops you into a remediation conversation. Getting it right at installation is the cheapest compliance decision you will ever make.
The way a deck is installed today decides whether it passes its first SB 721 / 326 inspection six to nine years from now — or fails it.
02 The D&B difference
What professional deck installation actually means
We install the entire deck as a single integrated assembly — structure, waterproofing, drainage, and railings built by one crew, backed by one warranty. That is what separates real professional deck installation services from a chain of subcontractors, each signing off only on their own scope.
Integrated assembly
Framing, waterproofing membrane, flashing, drainage, and railings go in as one continuous system built by one crew — so there are no unowned seams for water to find.
Custom deck design, built to code
From pedestal-paver rooftop decks to attached elevated decks, we build custom deck installations to your drawings — framed to current CBC, Title 24, and the 42″ / 4″ guardrail standard.
Single-vendor accountability
One CSLB-licensed deck installation company stands behind the whole deck — and is still here for your first SB 721 / SB 326 inspection six to nine years later.

05 Investment
How much a deck installation costs
Every deck installation is quoted after a site assessment — but this range reflects typical recent work and helps you budget the deck installation price early.
What drives the number
- Deck size and the number of decks across the property
- Structure — attached vs. freestanding, wood-frame vs. concrete / podium
- Walking surface and railing material selections
- Site access, staging, and crane / lift requirements
- Permit jurisdiction and plan-review timeline
- Waterproofing system and drainage complexity

06 Project example
A recent deck installation
An occupied apartment building in the Bay Area wanted to add private elevated decks to its top-floor units as an amenity upgrade — a new deck installation on an existing, tenant-occupied structure, with living space directly below every deck. D&B assessed the existing framing and attachment points, engineered code-compliant ledger connections into the building, and installed all 16 decks — framing, integrated waterproofing membrane, drainage, and 42″ guardrails — as one continuous scope. Because a single CSLB-licensed crew owned every layer, there were no subcontractor seams to fail and no water intrusion into the units below. Each deck passed inspection on the first walk and went straight into the property’s SB 721 compliance file.
They added sixteen decks to an occupied building without a single leak into the units below — and every one passed inspection the first time. Property Owner · Bay Area multifamily
07 Client feedback
What clients say
We needed decks added to an existing building, and every other deck installation company wanted to sub out the waterproofing. D&B did the whole thing in-house — one number, one warranty.
They gave us a clear deck installation estimate up front, held to it, and the decks passed inspection on the first walk. Easily the best deck installation experience we’ve had.
The as-built documentation went straight into our compliance file. We know exactly what the first SB 326 inspection will find.
08 FAQ
Deck installation questions
How much does deck installation cost in California?
Every deck is priced after a site assessment, but most commercial and multifamily deck installations start around $4,500 per deck. The price of a deck installation depends on size, structure, materials, waterproofing, and site access — we give you a firm number after reviewing the site.

Five stages: site assessment and design, permitting and engineering, installation, inspection sign-off, and warranty handoff. One CSLB-licensed crew handles every stage — no subcontractor handoffs.
Do you build custom decks?
Yes. Every install is a custom deck installation built to your drawings and your building’s structure — freestanding, attached, or rooftop, in pedestal pavers, lightweight concrete, or coated deck surfaces. A new deck installation is engineered to your loads, not a stock template.
