Office, Retail, Warehouse, and HOA Drywall Installation
We install drywall in four kinds of commercial spaces around Antioch: offices, retail shops, warehouses, and HOA-owned shared buildings. Fire-rated drywall goes into any of these projects when the plans call for it, typically along corridor walls, shared tenant walls, or fire-separation walls between sections of a larger building. The sections below cover what each type of commercial drywall installation involves.
Office Drywall Installation
Office drywall installation covers new interior walls and ceilings for suites, private offices, conference and meeting rooms, and the hallways connecting them. This is common work in professional office space along corridors like Delta Fair Boulevard and Hillcrest Avenue, where tenant improvement build-outs often mean framing and hanging new partition walls to divide open shell space into individual suites. Where the plans call for it, we install fire-rated drywall on hallway walls to meet the building's fire-separation requirements.
Retail Drywall Installation
Retail drywall installation covers storefronts, interior shop walls, and back rooms for stores and shopping centers, including build-outs at centers like Somersville Towne Center, Slatten Ranch Shopping Center, and The Crossings Shopping Center. A new tenant space typically needs walls framed and hung for the sales floor, fitting rooms or display areas, and a stockroom or back office. Where the plans call for it, we install fire-rated drywall on walls shared with the next shop to meet code between tenant spaces.
Warehouse Drywall Installation
Warehouse drywall installation covers break rooms, shipping and receiving offices, and the tall interior walls found in large industrial buildings, including light-industrial and distribution space along the Highway 4 and Wilbur Avenue corridors. These jobs often mean framing and hanging drywall at heights standard commercial crews don't handle daily, plus finishing smaller office and break room build-outs inside the larger shell. Where the plans call for it, we install fire-rated drywall on walls that separate one part of the building from another, such as a warehouse floor from an attached office or mezzanine.
HOA Drywall Installation
HOA drywall installation covers clubhouses, fitness rooms, mail rooms, and other shared spaces owned by the community rather than an individual unit owner, the kind of amenities found in master-planned communities like Lone Tree Estates. Because these projects are approved by a board rather than a single owner, the fixed-price quote and written schedule matter even more: they give the HOA board clear numbers and dates to review and approve before work starts, with no surprise costs to explain at the next meeting.

Commercial Drywall Installation Frequently Asked Questions
What permits and reviews does commercial drywall in Antioch require?
Commercial new construction and tenant improvements must follow the city's commercial submittal checklist, and the applicant self-certifies that everything is included, since incomplete submittals are not accepted. Every commercial project also needs Fire District plan review and approval, and projects serving food need Environmental Health approval. The Contra Costa County Fire Protection District's tenant improvement form, for example, says sprinkler modifications need plans from a C-16 licensed fire sprinkler contractor, reviewed before the work starts. Call Building Services at (925) 779-7065 before pricing walls, since moving or adding partitions can require sprinkler changes.
What makes a fire-rated commercial wall pass?
A typical one-hour rated wall on a commercial job is metal framing with one layer of taped 5/8-inch drywall on each side, running floor to deck, with fire-resistive caulk at the head-of-wall gap left for deflection. The rating comes from tested assemblies, using ASTM E119 or UL 263. Listed designs are not freely interchangeable, and a claim that a substitute is equal or better does not replace listing evidence. Penetrations and joints carry their own requirements in CBC sections 714 and 715, and who provides that firestopping is a frequent scope dispute between the general contractor and the drywall sub.
What does the framing and bracing behind commercial drywall have to do?
Nonstructural steel framing is typically specified to ASTM C645 and C754, with deflection limited to L/240 under a 5 psf lateral load, tightened to L/360 where a Level 5 finish or tile backing is indicated. Studs behind wall-mounted casework can need heavier gauge, and one airport specification sets 16-gauge minimum for partitions supporting casework. On seismic bracing, FEMA E-74 says partitions taller than 6 feet must be laterally braced to the structure, independent of any ceiling bracing. ASCE 7 Chapter 13 covers interior partitions and ceilings, and screw-attached gypsum board ceilings surrounded by walls braced to the structure above can qualify for an exception to separate ceiling bracing.
When is commercial drywall inspected, and what happens before taping?
The California Building Code says no gypsum board or its attachments may be covered or finished until the inspector of record or special inspector has inspected and approved it. Fire taping above ceilings at rated assemblies is a standard line item in drywall proposals, so confirm who carries it. In Antioch, inspection requests must be made by 1:00 PM the evening before, next-day inspections are not guaranteed, and the city recommends scheduling at least three business days ahead. Hold taping, finishing, and paint on the affected walls until the sign-off is in hand.
How is drywall work done in an occupied building or medical office?
In live spaces, the standard approach is a sealed temporary enclosure with a single access route, negative pressure inside the work zone, and HEPA-filtered air scrubbers. In healthcare settings, the CDC requires hospitals to perform an Infection Control Risk Assessment with a dust control plan before construction or renovation, and medical and dental tenants often adopt similar standards. Higher-risk containment calls for barriers that extend to the ceiling or deck above, with any penetrations sealed to the required fire rating. Night and weekend work often prices separately, since after-hours and occupied-space premiums appear as their own line item and overtime premiums are commonly excluded from base bids.
What accessibility work gets triggered by a tenant improvement?
When an existing commercial building is altered, CBC 11B-202.4 requires an accessible path of travel to the area of construction. When the adjusted construction cost is under a valuation threshold that is adjusted periodically, compliance spending is capped at 20% of that cost, and the priority order runs from an accessible entrance, to an accessible route, to an accessible restroom. Antioch's Building Division final inspection is not a verification of ADA compliance, and property owners and applicants remain responsible for meeting ADA requirements. Ask the design professional what your project triggers before walls are laid out.
Is there asbestos or lead in older commercial buildings?
Possibly. The Bay Area Air District enforces federal asbestos rules locally under Regulation 11, Rule 2, and Cal/OSHA presumes thermal insulation and surfacing materials in pre-1980 buildings contain asbestos until testing proves otherwise. Removing 100 square feet or more of regulated asbestos-containing material requires notifying the Air District at least 10 working days beforehand. For lead, EPA's renovation rule covers pre-1978 child-occupied facilities such as child care centers. Have the survey done before demolition or bids are finalized.
Why do commercial drywall bids vary so much, and what should they spell out?
Commercial jobs often use metal framing and fire-rated materials, and small tenant improvements carry higher mobilization fees than large projects. Sound-rated partitions cost noticeably more than a standard Type X partition. Finish levels must be assigned by area in the scope, and Level 5 is the level for critical lighting or high-gloss paint. Base bids commonly exclude overtime premiums, wood backing and blocking, hoisting, temporary partitions, dumpsters, and temporary power, and if the lowest bid leaves out head-of-wall firestopping the specs require, the scope gap should be closed before award.
What licenses does a commercial drywall contractor need in Antioch?
The C-9 classification covers laying out and installing gypsum board assemblies, including nonstructural metal framing, plus taping and texturing. A contractor's license is required for work over $1,000, and for smaller jobs that need permits or workers. Antioch also requires a business license: all entities and persons conducting business in the city, including subcontractors, need a current one, and approval can take two to four weeks. Related trades are licensed separately, including plumbing (C-36) and electrical (C-10).
What changes on public works projects like schools and city buildings?
Prevailing wages apply to public works over $1,000. Contractors and subcontractors at every tier must register with the Department of Industrial Relations, no contractor is permitted on a public works project without a registration number, and certified payroll records go directly to DIR. Registration is not required when the prime contract is $25,000 or less for construction, or $15,000 or less for maintenance, but prevailing wage still applies. Prime contractors also face fines when a required subcontractor is unregistered, so verify registration before subbing work.
