Commercial Deck Builders in San Francisco, CA

Yes, and usually two reviews rather than one. An occupiable roof deck needs a building permit through DBI, and the Planning Department reviews zoning, setbacks, height and historic status first. Roof decks at the rear of a lot or above certain heights, stair penthouses, decks in required yards and windscreens over forty-two inches are the features that most often trigger a thirty-day neighbourhood notification under Planning Code §311. We establish the path at scoping, because it sets the schedule more than the construction does.

Often more than one. Section 604 of the San Francisco Housing Code applies to apartment houses and hotels, requires inspection of one hundred per cent of exterior elevated elements, and is filed by affidavit with DBI Housing Inspection Services every five years. SB 721 covers rental buildings of three or more units on a six-year cycle, SB 326 covers HOA condominiums on a nine-year cycle. State law does not replace the local ordinance — a San Francisco building can owe both, with separate documentation for each.

Longer than anywhere else we work, and the variable is review rather than construction. Straightforward scopes can clear over the counter. Anything that reaches Planning adds its own review, and a §311 notification adds a thirty-day period on top. We give a schedule with the review path shown separately from the build, so a board is not voting on a start date that depends on an unknown.

Yes — that work is a large part of what we do here. The framing is a century old, the connections have usually been painted over rather than maintained, and the stair is frequently the only rear egress, so phasing matters as much as carpentry. We open a connection at assessment, price what is actually there, and keep a compliant path of travel in service while we work.

Position drives it more than area: at grade, at the rear elevation, or on the roof, in that order of cost. After that it is Planning exposure, the condition of what the new work lands on, and how much of the job is stairs — stairs cost more per foot than deck area. We quote a fixed written scope after a free on-site assessment.

Capped composite and PVC handle the constant damp with the least upkeep; wood is workable where the building calls for it, provided it is a species and finish chosen for slow drying rather than for an inland climate. The hardware matters more than the boards: hot-dip galvanised as a minimum, stainless at connections carrying load, and no mixed metals anywhere in the assembly.

That is the first question we answer, not the last. An occupiable roof deck adds live load to a structure that may have been designed only for maintenance access, and the fire-resistive rating of the roof assembly has to survive the build. Where the structure needs reinforcement we say so before design, because it changes both the drawings and the budget.

Commercial, multifamily and HOA properties only — apartment houses, condominium associations, hotels and mixed-use buildings. We work as deck contractors San Francisco boards and managers hire directly rather than through a general, and as a deck builder serving the wider Bay Area we are not set up for single-family backyard work — saying so up front saves everyone a site visit.

Yes, and on a rear stair that is not negotiable — egress has to stay open. Work is phased by stack or by elevation, temporary protected access is provided where the existing stair comes out, and the schedule goes to the board before contracts are signed.
