Why homeowners choose us
The safe way to hire an ADU contractor.
Licensed & vetted builders
Every contractor we work with carries an active CSLB license, bonding, and workers' comp — vetted before they ever bid on your project.
Competitive, itemized bids
Apples-to-apples bids on identical scope, so you compare real numbers — not sales pitches. Homeowners typically save 12–22% off the first quote.
Design + permits in-house
We draw permit-ready plans and handle LADBS approvals, so your build never stalls on red tape or an unqualified crew.
Affordable, flat-rate construction
Honest per-square-foot pricing that starts at $275/sq ft — you know your number before you commit to anyone.
One point of contact
One accountable team from permit to move-in — no finger-pointing between separate designers, engineers, and builders.
600+ ADUs delivered
A 5.0-rated track record across Los Angeles — real projects you can walk through, not renderings or promises.
Why ADU Resource Center
Not just a contractor — a whole team.
Hiring a random general contractor for an ADU is risky: ADUs have their own permitting, setback, and utility rules. We give you ADU specialists for design and permits, plus vetted builders for construction — coordinated under one roof.
Design + permits in-house
We draw permit-ready plans and shepherd them through LADBS so your build doesn't stall on red tape.
Vetted building partners
Licensed, bonded, insured contractors with real ADU track records — matched to your project and budget.
Competitive, honest bids
Apples-to-apples itemized bids on identical scope, so you compare real numbers — not sales pitches.

Buyer's guide
How to vet an ADU contractor.
Whether you hire us or not, here's the checklist that protects you from the most common (and expensive) ADU contractor mistakes.
✓Licensed & bonded
Verify an active CSLB license (B or C-class), bonding, and workers' comp. We only work with contractors who clear this — every time.
✓ADU-specific track record
ADUs have their own permitting, setback, and utility quirks. Ask how many they've actually completed, not just 'years in business.'
✓Transparent, itemized bids
A real bid breaks out hard costs, soft costs, and allowances. Vague lump sums hide change-order surprises.
✓Permit & design capability
A contractor who can't navigate LADBS will stall your project. We handle design + permitting in-house so nothing falls through the cracks.
✓Local references & reviews
Recent LA-area projects you can verify, plus a real review history. We've delivered 600+.
✓Single point of accountability
Avoid finger-pointing between separate designers, engineers, and builders. One coordinated team owns the outcome.

What clients say
“They handled everything — design, permits, construction. Our detached ADU in Burbank went from lot survey to move-in-ready in under a year. We're already renting it out.”

Questions
ADU contractor questions, answered.
Still have a question? Ask us during your free consultation.
Are your ADU contractors licensed and bonded?
Yes — every contractor we work with carries an active CSLB license, bonding, and workers' compensation insurance. We vet licensing and insurance before any contractor bids on your project, so you never have to chase paperwork or worry about an unlicensed crew.
Do you build the ADU yourselves or subcontract it?
ADU Resource Center handles design and permitting in-house, then matches your permit-ready plans to vetted, licensed building partners who construct it. You get specialist design + LADBS expertise from us and competitive construction pricing from our contractor network — with us staying your single point of contact throughout.
How do you vet the contractors?
We confirm active licensing, bonding, and insurance; review their ADU-specific track record (not just general construction); check recent LA-area references; and require itemized bids. Contractors who don't meet the bar don't bid on your project.
How much does it cost to build an ADU in Los Angeles?
We build at a flat construction rate starting at $275/sq ft (basic), $300 (mid-range), and $325 (luxury). Garage conversions are typically the most affordable path; detached ADUs cost more but add the most value. Use our ADU cost calculator for a quick estimate, or book a consultation for a real number on your lot.
How long does an ADU take to build?
Design and permitting typically run 2–4 months, and construction another 4–8 months depending on scope — roughly 6–12 months total from first call to move-in. Pre-approved/standard plans can shorten the permitting stage significantly.
What areas of Los Angeles do you serve?
We serve Los Angeles and the surrounding region — including Glendale, Burbank, Pasadena, the San Fernando and San Gabriel Valleys, Long Beach, and nearby Orange County. If you're in greater LA, we can almost certainly help.
