New Deck & Balcony Construction for California Commercial Properties
Ground-up balcony and deck systems for new commercial multifamily, mixed-use, and HOA development — engineered for the building’s full 50-year life, not just the certificate of occupancy.

01 Why it matters
The first inspection cycle starts the day you break ground
In California, every commercial balcony and deck is an exterior elevated element (EEE) — and every EEE faces a mandatory SB 721 or SB 326 inspection every six to nine years. The assembly you build today is the exact assembly that gets inspected. There is no reset.
Build it with fragmented trades — a framing crew, a separate waterproofer, a separate railing installer, each signing off only on their own scope — and the seams between those trades become the points where water gets behind the membrane and rot begins. On too many buildings that failure is already underway before the property is ten years old.
A brand-new building that fails its first inspection is the most expensive possible way to learn this. New construction is the one moment in a property’s life when compliance risk can be engineered out entirely.
Engineering decisions made now determine whether you clear the first SB 721 / 326 inspection in six to nine years.
02 The D&B difference
One system, one vendor, one warranty
We build the balcony and deck envelope the way it actually has to perform — as a single integrated assembly, not a relay race between subcontractors.
Integrated assembly
Structure, waterproofing membrane, flashing, drainage, and railings are built as one continuous system by one crew — so there are no unowned seams for water to find.
Design-team coordination
We work directly from your architect’s and structural engineer’s drawings — handling RFIs, framing to current CBC and Title 24, and flagging EEE detailing issues before they reach the field.
Single-vendor accountability
One CSLB-licensed contractor stands behind the entire assembly — and is still here for your first SB 721 / SB 326 inspection six to nine years later.
03 How a project runs
From plans to inspector sign-off
-
01
Design coordination
We review balcony and deck details with your architect and structural engineer, flag code and EEE issues, and align on materials and waterproofing approach before anything is ordered.
-
02
Permitting & engineering
We coordinate stamped engineering where required and move the assembly through the building department’s permit process.
-
03
Construction
Our in-house CSLB-licensed crew frames, waterproofs, flashes, drains, and installs railings as one continuous scope — no handoffs, no unowned interfaces.
-
04
Inspector sign-off
We walk the completed assembly through building-department inspection and resolve any items directly.
-
05
Warranty & handoff
You receive as-built documentation for the property’s compliance file — and a single contractor to call for the first inspection cycle and beyond.
04 Scope
What’s included in a D&B balcony & deck build
A complete commercial balcony and deck build, from plan coordination through the documentation your compliance file will need.
- Architect & structural engineer coordination — plans, calcs, RFI handling
- Framing — pressure-treated joists, blocking, ledger flashing per CBC 1604.8.1
- Continuous waterproofing membrane integrated with the weather-resistive barrier and flashing
- Walking surface — pedestal pavers, lightweight concrete, or coated deck
- Code-compliant guardrail systems — 42″ height, 4″ sphere rule, load-tested
- Drainage — scuppers, internal drains, verified slope to drain
- Inspector sign-off + as-built documentation for the compliance file
Built to current code: CBC 1604.8.1 ledger connections · ASCE 7 load criteria · Title 24 · 42″ / 4″ guardrail standard
05 Investment
What a commercial build typically costs
Every commercial project is quoted after a plan review — but these ranges reflect typical recent new-construction work and help you budget early.
What drives the number
- Number and size of balconies and decks across the building
- Structural system — wood-frame vs. post-tension or concrete podium
- Walking surface and railing material selections
- Site access, staging, and crane / lift requirements
- Permit jurisdiction and plan-review timeline
- Schedule compression and phasing around other trades
Ranges reflect typical recent commercial work. Final pricing follows a plan review — no obligation.
06 Project example
A recent ground-up build
A ground-up multifamily build in the Bay Area. D&B was brought in at design development to coordinate balcony detailing with the project architect and structural engineer — resolving ledger-connection and flashing details on paper, then building the full envelope (framing, membrane, drainage, railings) as a single continuous scope.
Bringing the balcony contractor in at design phase — not after framing — is what kept the assembly out of the remediation conversation entirely. Project Owner · Bay Area multifamily development
07 Client feedback
What developers say
They read the structural set, flagged two EEE detailing issues before we broke ground, and built the whole balcony envelope themselves. One number to call, one warranty.
We used to bid framing, waterproofing, and railings separately and then own the seams. Handing the entire assembly to one CSLB-licensed contractor took that risk off our plate.
The as-built documentation they handed over went straight into our compliance file. We know exactly what the first SB 326 inspection will find.
08 FAQ
New construction questions
Can you build from our architect’s and engineer’s plans?
Yes. Most of our new-construction work starts from a complete design set. We review the balcony and deck details, handle RFIs, and build to the stamped drawings — coordinating directly with your design team throughout.
What code do commercial balconies and decks have to meet in California?
Exterior elevated elements must meet the current California Building Code — including CBC 1604.8.1 ledger-connection requirements, ASCE 7 load criteria, Title 24, and the 42-inch height / 4-inch sphere guardrail standard. We build to current code so the assembly passes inspection on the first walk.
How long does a commercial balcony and deck build take?
Typically 2–6 weeks per balcony cluster, depending on the number of assemblies, structural system, and site access. For a full multifamily building we phase the work around the other trades and give you a project-specific schedule after plan review.
Do you coordinate with our structural engineer?
Yes. We coordinate stamped engineering where required and work the connection details, load paths, and waterproofing interfaces with your engineer of record before construction starts.
How does building it right now affect future SB 721 / SB 326 inspections?
The assembly you build today is the one inspected every six to nine years. A build done right — integrated waterproofing, correct flashing, code-compliant railings, fully documented — clears its first inspection cycle with zero remediation findings. That is the entire point of getting it right at construction.
What’s included in your warranty?
You receive a workmanship warranty on the assembly plus as-built documentation for the property’s compliance file. Because one CSLB-licensed contractor built the whole envelope, there is one vendor accountable — not a finger-pointing chain of subcontractors.
Do you handle permits?
Yes. We move the balcony and deck scope through the building department’s permit process and walk the completed assembly through inspection.
