Every GC in Los Angeles has had the same week: framing is done, the inspection passed, and the stucco sub you lined up two months ago stops answering the phone. A residential job in LA runs through a long chain of trades, and one missing link stalls the schedule for everyone behind it.
Here's how to build a sub bench that holds up: where to look, how to vet, and how to scope work so the bids are actually comparable.
Where LA GCs actually find subs
1. Referrals from your existing subs. Your best framer knows a good stucco crew because they've worked the same jobs. Ask every sub you trust who they'd want following them.
2. Supply houses. Counter staff at lumber yards, plumbing supply and electrical distributors see which contractors pay their accounts and keep busy. Ask.
3. Facebook groups and trade communities. LA has large, active contractor groups. They're good for finding people who are available now; vet carefully.
4. Job boards built for bidding. Posting a defined scope publicly brings in subs you don't know yet. On Bidroom, you post the trade, scope and neighborhood, and licensed contractors send a price and timeline. See what's posted on the LA jobs board. Specialty trades in the directory include electricians, plumbers, roofers, HVAC, concrete, carpenters, flooring, painters and landscaping.
5. Public license data. The CSLB lets you look up licensees by classification and location. It's a long list without much signal, but it's useful for niche trades.
Vet every sub in about 15 minutes
Before you put a sub on a job, check four things.
1. License and classification
Look up the license on the CSLB's Check a License page. Confirm: - Status is active. - The classification matches the work (C-10 electrical, C-36 plumbing, C-35 lathing and plastering for stucco, C-39 roofing, C-20 HVAC, and so on). - The business name matches the one on their bid and their insurance. - There are no recent disciplinary actions or suspensions.
In California, work over $1,000 in combined labor and materials requires a license, and the CSLB treats hiring an unlicensed sub as a problem for the GC too. Full walkthrough in our CSLB license check guide.
2. Workers' compensation
The CSLB record shows whether the license has a workers' comp policy on file or an exemption, meaning the contractor certifies they have no employees. A sub with a crew and an exemption is a red flag. If they get hurt on your job, the exposure can land on you. Ask for a current certificate. See our California workers' comp guide.
3. General liability insurance
Ask for a certificate of insurance naming your company as additional insured, and check that the dates cover the job.
4. Recent work
Ask for two or three recent jobs of similar scope in LA, with a contact for each. Call one.
Write a scope that gets comparable bids
Most "bad bids" come from a vague scope. Before you send work out, write down:
- Exact work included and excluded. For example: "3-coat stucco, lath included, color coat by others; scaffolding by GC."
- Plan sheets and specs that apply.
- Who supplies materials.
- Schedule window and how it depends on other trades.
- Site conditions: access, parking, hillside or tight lot, occupied home.
- Inspection responsibilities: who calls them, and whether a deputy inspector is required.
- Payment terms and retention.
Send the same scope to three or more subs, and you can compare price to price.
Red flags when hiring a sub
- They won't give a license number, or the name on the license doesn't match.
- They ask for a large deposit before showing up. Mobilization payments are normal for some trades, but tie them to materials delivered or work started.
- They have a crew but a workers' comp exemption on file.
- They want to "skip the permit" or say an inspection isn't needed.
- Their bid has no exclusions. Every honest bid lists what isn't included.
Keep good subs coming back
The subs worth having have choices. They pick GCs who: - Pay on time. This is the biggest one. - Have the site ready when they show up. - Answer questions fast and make decisions. - Put change orders in writing before the work, not after.

A simple bench-building routine
- Keep a spreadsheet by trade: name, license number, comp status, last job, a rating out of 5.
- Aim for at least two to three vetted subs per trade you use regularly.
- Every time a job is scoped, send it to at least one sub you haven't used before.
- Re-check licenses and insurance once a year.
Post your next scope
If you're a GC with work to fill, you can post a project on Bidroom and let licensed LA subs bid on it. If you're a sub looking for work, browse open jobs on the jobs board or see how bidding works.
