- Orange & LA County Where we build
What we build
Residential work, start to completion. We pull the permits, run the crew, and hand you back a finished room.
-
Home Remodels
Whole-house and single-room remodels. We handle demo, framing, plumbing, electrical, drywall, finishes, and the permits behind all of it.
-
Room Additions
Adding square footage to a house you already like. Foundation, framing, roof tie-in, and the interior finish, matched to the existing structure so the addition doesn't read as an addition.
-
Kitchens & Baths
The two rooms that decide how a house feels day to day, and the two most people get wrong. Cabinetry, tile, counters, fixtures, lighting, and the rough-in work underneath.
-
ADUs
Detached and attached accessory dwelling units, for rental income or for family. Built to current California ADU code and inspected through to final sign-off.
-
Electrical Upgrades
Panel upgrades, rewiring, and new circuits, typically as part of a remodel. If your addition or kitchen needs the service upgraded, that gets scoped and scheduled with the rest of the work.

We're licensed with the California Contractors State License Board under license #1151865, and we're bonded and insured. If something goes wrong on your job, that coverage is what makes it fixable. Our work carries a one-year craftsmanship warranty from the day the job closes out.

Questions homeowners ask
Are you licensed and insured?
Yes. Guerrero Construction holds California contractor license #1151865 and carries both bonding and liability insurance. You can verify the license directly on the CSLB website at cslb.ca.gov before you hire us or anyone else.
Do you charge for estimates?
No. The walkthrough and the written estimate are free. You'll get the scope and the price before you commit to anything.
Do you pull the permits?
Yes. Permitting is handled as part of the job for work that requires it: additions, ADUs, structural changes, and electrical service work. You don't manage the city; we do.
How long does a project take?
It depends on scope and on how quickly the city moves. A bathroom is usually a matter of weeks; an addition or an ADU runs months, and permitting is often the longest part. You'll get a realistic schedule with your estimate rather than an optimistic one.
What areas do you serve?
Orange County and Los Angeles County.
What's covered by the warranty?
Our craftsmanship is warranted for one year from project completion. If something we built fails in that window, we come back and fix it. Manufacturer warranties on materials and appliances are separate and are passed through to you.
Do you build ADUs?
Yes, attached and detached, built to current California ADU requirements and carried through final inspection. ADUs are one of the most common projects we're called for in both counties.
How do payments work?
Payments are tied to milestones and laid out in the contract before work starts. California law limits what a contractor can collect up front on residential work.
