What to Expect: Our Commercial Construction Process

Commercial projects have unique requirements — tighter timelines, code compliance, and minimal business disruption. Here's how we deliver commercial projects on time and on budget.

1

Project Consultation & Needs Assessment

We meet at your property to understand your business needs, tenant requirements, and project goals. We assess the space, discuss ADA compliance, review lease requirements and tenant improvement allowances, and establish a timeline that works around your operations.

1–2 weeks
2

Detailed Proposal & Contract

We deliver a comprehensive proposal with scope of work, materials, pricing, schedule, and a clear payment structure. We address ADA compliance, building codes, and any special requirements. You review and approve before we proceed — no hidden costs or scope changes without written approval.

1–2 weeks
3

Permitting & Scheduling

We handle all permits and coordinate with building departments, fire marshals, and health inspectors. We schedule work to minimize disruption — after hours, weekends, or phased construction — so your business can keep running. We coordinate with property managers and other trades as needed.

2–4 weeks
4

Construction & Build-Out

Our experienced crews execute the build-out to commercial standards. We manage all trades — framing, drywall, electrical, plumbing, HVAC, flooring, and finishes. We hold regular progress meetings and keep you informed at every stage. We meet code requirements for occupancy and safety.

Varies by scope
5

Final Inspection & Turnover

We coordinate final inspections, address any city corrections, test all systems, clean the space, and hand over a ready-to-occupy property. We provide as-built documentation, warranties, and operation instructions for any installed systems.

Commercial Construction Cost Expectations

Commercial construction pricing depends on the project type, building requirements, and level of finish. Here's what Bay Area businesses can generally expect:

  • Tenant improvements typically run $40 to $150 per square foot depending on scope, existing conditions, and finish level
  • Office build-outs range from $50 to $200 per square foot, with higher costs for private offices, conference rooms, and specialized spaces
  • Retail space renovations run $60 to $250 per square foot depending on display requirements, lighting, and custom fixtures
  • Restaurant renovations typically cost $100 to $300 per square foot due to kitchen equipment, hood systems, and health code requirements
  • Multi-unit renovation pricing varies widely based on unit count, scope per unit, and phasing requirements
  • Factors that affect pricing include building type, ADA compliance needs, scope, timeline, after-hours work, and coordination with other building tenants

Commercial projects often involve a tenant improvement allowance from the landlord. We work within your allowance and help you maximize its value. Contact us for a detailed proposal tailored to your project.

Commercial Materials & Systems We Install

Commercial construction requires different materials and systems than residential work — rated assemblies, ADA-compliant fixtures, and durable finishes. Here's what we commonly install:

Commercial-grade flooring including VCT, luxury vinyl tile, commercial carpet tile, and polished concrete
Commercial doors and hardware — fire-rated, ADA-compliant, with panic hardware and access control integration
Acoustic ceiling systems — drop ceilings, grid systems, and acoustic panels for office and retail spaces
Commercial lighting including LED fixtures, emergency lighting, and exit signs per code requirements
ADA-compliant restroom fixtures, grab bars, and accessible layouts meeting current code requirements
Glass partitions, storefronts, and curtain wall systems for offices and retail spaces
Fire-rated wall assemblies, smoke barriers, and fire stopping for multi-tenant buildings
HVAC, electrical, and plumbing systems coordinated with building infrastructure and utility providers

Frequently Asked Questions

Commercial Construction Questions Businesses Ask

Here are the questions we hear most often from business owners and property managers before starting a commercial project.

Yes. We understand that business interruption costs money. We routinely work nights, weekends, and holidays to minimize disruption to your operations and neighboring tenants. We can also phase construction to keep parts of your space operational during the build-out. We'll discuss scheduling options during your consultation.

Absolutely. We're experienced in ADA compliance requirements and current building codes throughout the Bay Area. We handle all permitting, plan submittals, and inspections. We coordinate with building departments, fire marshals, and health inspectors so you don't have to. Every project we complete meets or exceeds code requirements.

Yes. We regularly work within landlord-provided tenant improvement allowances. We provide a detailed scope that fits your allowance and help you prioritize what matters most. If your needs exceed the allowance, we'll clearly identify what's included and what would be an upgrade so you can make informed decisions.

Absolutely. We understand commercial building etiquette — coordinating access, loading docks, freight elevators, and shared utilities. We communicate proactively with property managers and minimize disruption to neighboring tenants. Many property managers specifically request us because of our professionalism on multi-tenant projects.

It varies widely by scope. A small office build-out might take 4-6 weeks, while a restaurant renovation or multi-unit project could take 3-6 months. Permitting alone can take 2-4 weeks depending on the city. We provide a detailed timeline during your consultation and update it as the project progresses.
