Construction Types
We Work With Every Type of San Francisco Deck & Balcony
Wood Decks
Much of San Francisco's elevated wood stock sits on Victorian, Edwardian, and mid-century multifamily buildings — redwood ledgers and joists retrofitted over decades of remodels. Each deck building era used different flashing and fastener standards, and in a salt-air city, we know which vintages need the closest look before compliance sign-off.
Concrete Balconies
Mid-rise and high-rise condos across SoMa, Rincon Hill, and Mission Bay use suspended concrete balconies with topical membranes and applied coatings. Spalling from chloride exposure, flashing separation at door thresholds, and drain outlet corrosion are the three repeat issues our deck inspector team targets on every walk.
Composite Decks
Newer townhome and condo projects — Dogpatch, Mission Bay, Portrero — have moved to composite boards over engineered framing. The finish hides joist condition, so our home inspection deck protocol includes lifting boards at the ledger and outer corners rather than certifying off a surface walk.

Local Expertise
Why San Francisco, Specifically
San Francisco is the one California city where three
separate inspection regimes overlap: SB 721 for apartments, SB 326 for
condos, and the City's own Section 604 ordinance — which requires
inspection of every Exterior Elevated Element on buildings with five or
more dwelling units. A single building often falls under two regimes at
once. The california balcony inspection law sets the floor; SF Section
604 layers on top. Running all three through the same certified team is
the only way to avoid duplicate scopes and conflicting reports.
San Francisco's building inventory is also uniquely
weathered. The marine layer, salt air, and constant humidity drive
corrosion at fastener level and membrane degradation at coating level
— conditions rare almost everywhere else in California. When an owner
searches for a deck inspection near me in SF, they need a team that
knows the difference between fog-belt rot in the Sunset and south-facing
UV wear in Noe Valley. We've walked enough buildings across the seven
square miles to recognize those patterns on sight, which keeps our
california deck inspections tight, on scope, and defensible under DBI
review.

Climate Note
San Francisco's salt-air fog and persistent humidity drive fastener corrosion faster than any inland California market. Combined with wind-driven winter rain at wall-to-deck tie-ins, these conditions make routine moisture inspection non-negotiable — visual walks alone miss the damage until structural failure is already underway.
Common Problems
What We See Most Often in San Francisco
Issues that repeat across the local building stock — from climate, construction era, or common materials in this area.
Salt-air corrosion on connection hardware
Joist hangers, lag bolts, and post bases on San Francisco decks corrode faster than inland equivalents. A deck safety inspection here includes physical hardware probe-testing, not just visual review — hidden section loss is the single most common Section 604 failure we document.
Rot behind Edwardian and Victorian ledgers
Retrofitted decks on older SF multifamily buildings often carry ledgers anchored to original framing with limited flashing. Water tracks in from wall siding above, and by the time a deck inspection company is called, the rot has usually been progressing for years behind finished interior walls.
Waterproof membrane end-of-life on 2000s condos
Topical membranes on SoMa and Mission Bay condos built between 2000 and 2010 are failing at door thresholds, drains, and wall terminations. This finding appears in nearly every deck inspection report we deliver for condo buildings of that era.
Undersized hardware and non-compliant deck footings
Retrofits from earlier code cycles frequently leave undersized tie-downs and shallow footings behind. A proper deck footing inspection identifies these before the DBI review flags them, which shortens permit turnaround and keeps the project on schedule.
Guardrails below current code height
Many older SF condo and apartment balconies still carry 36" or even 34" guardrails where 42" is now required. We flag and correct these within the same project scope.
Who We Serve
Property Types We Work With
Apartment Buildings
SB 721 inspections for San Francisco apartment buildings on the 6-year cycle, coordinated with any overlapping Section 604 obligation so owners aren't paying twice for overlapping scopes. Full tenant-access coordination included.
Condominiums
SB 326 inspections for condo associations across SoMa, Mission Bay, Pacific Heights, and the Avenues on the 9-year cycle. Engineer-signed reports included. When an owner asks for a condo inspection near me in SF, our team is usually already working on a nearby building that week.
HOA Communities
Board-ready reporting, DBI deck permit filings, and final compliance letters formatted for HOA archive, lender reviews, and insurance carriers. We also supply a clean condo checklist inspection format HOAs use for annual walk-throughs and reserve-study documentation.
Multi-Family Housing
Mixed-use buildings, TIC conversions, townhomes, and multifamily stock across all SF neighborhoods — with scope adjusted for the specific ordinance the property falls under.

Proof
Trusted by Property Managers in San Francisco
Our Pacific Heights building fell under both SB 326 and Section 604 — the ABD team ran both scopes in a single visit and closed everything out through DBI in weeks, not months. The deck inspection report was clear enough that our reserve-study consultant built directly off it.
We manage several SoMa mid-rises and needed a deck inspection company that actually understands the Section 604 process. ABD handled the filings, the tenant notices, and the post-repair engineer letter cleanly — it's the first time in years our owner didn't have to chase paperwork.

FAQ
Questions from San Francisco Property Owners
My building is subject to Section 604 — do I still need SB 721 or SB 326 separately?
Yes, in most cases. Section 604 is a San Francisco ordinance covering Exterior Elevated Elements on buildings with five or more units; SB 721 and SB 326 are state laws covering apartments and condos respectively. A single building often falls under two regimes at once. We run the overlapping scopes as a single project and issue separate signed letters for each, so nothing is duplicated and nothing is missed.
Does San Francisco require its own permit for deck and balcony repair?
Yes — San Francisco DBI handles all permitting. Any structural repair that replaces more than 25% of a deck or balcony assembly requires a deck permit, and Section 604--driven repairs have their own filing track. We prepare, submit, and close out the permit as part of every project.
What does a San Francisco deck or balcony inspection typically cost?
The home inspection cost in California is typically higher in SF than inland markets because of salt-air inspection requirements, overlapping regimes, and DBI filing overhead. For an apartment property, SB 721 pricing is based on unit count; for condo associations, the condo inspection price depends on the number of buildings, elevated elements, and whether Section 604 applies. We provide a fixed-price quote after a free on-site assessment — no surprise line items.
