Quick answer: Look for a licensed General Building (Class B) contractor with real commercial TI experience, proof of bonding and insurance, and references from projects similar in scope to yours — a residential-focused GC isn’t automatically equipped for commercial permitting. APLA Construction (CA Lic #1136359) has handled small commercial build-outs throughout Los Angeles.
Hiring a contractor for a commercial build-out is a different decision than hiring one for a home remodel — you’re usually working against a lease start date, a landlord’s TI allowance, and a business that needs to open on schedule. APLA Construction (CA Lic #1136359) has built out offices, retail spaces, restaurants, and warehouses across Greater Los Angeles, and this guide covers what actually separates a contractor who can deliver a commercial project from one who can’t.
Verify the License and Insurance — Then Check the Classification
Any contractor taking a job worth $1,000 or more in labor and materials in Los Angeles, or any job that needs a building permit, must be licensed by the Contractors State License Board (CSLB) — verify this at cslb.ca.gov before any conversation goes further. For commercial work specifically, also confirm:
- Classification — a Class B General Building contractor can oversee a full commercial TI; a specialty (C-license) contractor is limited to their trade and can’t legally act as the general contractor on a multi-trade build-out
- General liability insurance — commercial leases typically require $1M–$2M in coverage, and your landlord’s property manager will usually ask for a Certificate of Insurance naming the landlord as additionally insured before construction starts
- Workers’ compensation — required if the contractor has employees; ask to see the certificate directly rather than taking their word for it
- Bond — California requires a $25,000 contractor’s bond minimum; larger commercial GCs often carry additional bonding for bigger projects
Ask About Permit and Agency Experience Specific to Your Project Type
Commercial permitting varies a lot by use. A contractor who’s great at office TIs may have never pulled a health department permit for a restaurant, or coordinated a fire sprinkler redesign for a warehouse. Ask directly:
- “How many [restaurant / office / retail / warehouse] build-outs have you completed in the last two years?”
- “Have you worked with LA County Environmental Health / South Coast AQMD / [your city’s] fire department on a project like mine?”
- “Can I see photos or a reference from a similar completed project?”
A contractor who can answer these specifically — not generically — is far more likely to hit your permit timeline. See our guides on restaurant build-out permitting and warehouse/industrial build-outs for what’s involved in those project types specifically.
Understand the TI Allowance and Who’s Actually Paying
Before you sign a contract, know how your lease’s tenant improvement allowance works:
- Get a written estimate before signing your lease — negotiating your TI allowance after signing means you’ve lost your leverage
- Ask whether the contractor will work directly with your landlord’s property manager — many commercial leases require landlord approval of contractors and plans before work begins
- Clarify what happens if costs exceed the allowance — get this in writing as part of your contract, not a verbal understanding
Red Flags Specific to Commercial Contractors
- No prior commercial work, only residential — commercial building codes, occupancy rules, and agency coordination are different enough that residential-only experience is a real gap
- Vague answers about permit timelines — an experienced commercial contractor in LA can give you a realistic range for LADBS plan check based on your project type, not just “it depends”
- Reluctance to provide a Certificate of Insurance — this is a standard, immediate request; hesitation is a warning sign
- Pressure to start work before permits are pulled — unpermitted commercial work can result in a stop-work order that costs far more time than waiting for the permit
- No fixed-price or clearly-scoped contract — commercial projects should have a detailed scope of work, not a rough verbal estimate
How to Structure the Bidding Process
- Get at least 3 bids from contractors with direct experience in your project type (office, retail, restaurant, warehouse)
- Make sure each bid is based on the same scope of work and drawings — comparing a detailed bid to a rough one isn’t a fair comparison
- Ask each bidder for two references from projects completed in the last 18 months
- Confirm each bidder’s timeline estimate includes permit review time, not just construction days
Frequently Asked Questions — Choosing a Commercial Contractor in LA
Do I need a General Building (Class B) contractor for a commercial TI?
For any project involving more than one trade — which covers almost all commercial build-outs — yes. A single-trade specialty contractor legally cannot act as the general contractor coordinating the full scope.
Should my landlord approve my contractor before I sign a contract?
Check your lease — many commercial leases in Los Angeles require the landlord or property manager to approve the contractor and construction plans before work begins, so confirm this before finalizing anything.
How many bids should I get for a commercial build-out?
At least three, from contractors with direct experience in your specific project type — a contractor experienced in office TIs isn’t necessarily the right fit for a restaurant or warehouse project.
What insurance should a commercial contractor carry?
At minimum, general liability insurance (commonly $1M–$2M for commercial leases) and workers’ compensation if they have employees — ask for a Certificate of Insurance naming your landlord as additionally insured if your lease requires it.
How can I check if a contractor has commercial experience, not just residential?
Ask for photos, addresses, or references from completed commercial projects specifically, and ask how they’ve handled permitting with the relevant agency for your project type (building department, health department, fire department, or AQMD).
