If you are bidding a podium project, a wrap apartment community, or a tilt-up plaster scope, the difference between hitting your schedule and explaining a four-week slip to ownership often comes down to one trade: stucco. Here is the vetting checklist we wish more PMs ran before they handed out a stucco scope.
1. License + classification (and verify it)
In California, look for an active C-35 Lathing and Plastering contractor or a B General Building with C-35 supervision in place. Verify the number at cslb.ca.gov — confirm active status, no disciplinary action, and a recent renewal. A clean CSLB record is the bare minimum.
2. Insurance limits and additional insured
Get a current Certificate of Insurance: General Liability with at least $1M / $2M aggregate, Workers’ Compensation per California statute, and Auto Liability. Confirm the sub will name your firm and the owner as additional insured and waive subrogation — most master subcontract agreements require it.
3. Bonding capacity
For projects above $1M of stucco scope, ask the sub for a current letter from their bonding agent stating single-job and aggregate capacity. A real bonding letter tells you a lot about the financial backbone of the company — small subs that bid above their bonding limits are a project risk.
4. Crew capacity and self-perform percentage
Ask flat-out: how many crews do you run, what is each crew's weekly brown-coat production, and what percentage of the work is self-performed vs. sub-subbed? On commercial stucco, you want a sub that self-performs lath, scratch, brown, and finish — not someone who is going to broker your job to three smaller crews you have never met.
5. Scaffold and equipment
Does the sub own and install their own scaffold, or are they hiring a third-party scaffold contractor? Owned scaffold means tighter schedule control and one less day-rate creep risk on your job. Ask about owned mixers, mast climbers, and lifts as well.
6. Reference projects of similar size and type
Three references from completed projects within the last 24 months, ideally with another GC's superintendent's direct phone number. Drive by at least one completed project and look at the wall. If you can spot patches, mismatched textures, or hairline cracking patterns at openings, that is your answer.
7. Submittal turnaround
Ask the sub how long they need for a complete submittal package: mock-up boards, control joint layouts, color samples, manufacturer cut sheets, and shop drawings if EIFS is in scope. The professional answer is 5–10 business days from contract execution. "We'll get you something" is not an answer.
8. Mock-up willingness
A real stucco sub will mock up a 4×4 sample on the actual building before committing the elevations. If they push back on that, walk away — you are going to be arguing about color and texture on every floor for the duration of the job.
9. Communication cadence
Who is your point of contact during construction — the owner, a PM, a foreman? Will they attend weekly OAC meetings? Are they reachable on weekends if there is a weather issue mid-pour? Bad communication is the single biggest source of stucco-related schedule slips.
Red flags worth walking away from
- Bid is 25%+ below the rest of the field. They are either missing scope, planning to cut crew quality, or do not understand the work.
- No physical office or yard. Stucco subs need a real laydown yard. A PO box is a flag.
- Cannot produce a sample of past commercial work the same size as yours. Residential subs cannot scale to mid-rise without learning on your job.
- Resistant to mock-ups, submittals, or pre-installation meetings. You will pay for this resistance in re-work.
