The Call That Changed Everything
Let me tell you about a call I got last year.
It was 7 PM on a Tuesday. A woman in Tustin - let's call her Patricia - was crying. She'd hired a contractor six months ago. They'd taken $60,000 as a deposit. Then they disappeared. No permits. No construction. No returned phone calls. Just an empty bank account and a hole in her backyard.
She found our website because her neighbor had just finished an ADU with us.
Here's what I told her: "Patricia, I'm sorry you're going through this. Here's what we're going to do. We'll pull your property records tomorrow. We'll see what permits, if any, were pulled. We'll figure out what's salvageable. And as your full-service ADU contractor, we'll build you an ADU that makes you proud."
The previous contractor had pulled nothing. The $60,000 was gone.
She came to our office the next day. We reviewed her situation. The previous contractor had pulled nothing. No permits. No plans. No engineering. The $60,000 was gone.
We started from scratch. Eight months later, Patricia had a beautiful 650 sq ft ADU. She now rents it for $2,900/month. Her nightmare became her best investment.
"I wish I'd found you first. The stress of the first contractor almost made me give up. You made it easy."
That's what we do. We make it easy.
In this guide, I'm going to walk you through exactly how we do it. No secrets. No hidden agendas. Just the process that has worked for 400+ Orange County homeowners.
What You'll Learn in This Guide
What "Full-Service" Actually Means
In our industry, "full-service" gets thrown around like confetti. Let me tell you what it actually means when you work with us.
One Point of Contact
One phone number to call. One person who knows your project. No "that's not my department" runaround. Accountability from start to finish.
End-to-End Permitting
We submit to the city, track plan check progress, handle corrections, get the permit, schedule inspections, and manage final CO. You don't go to city hall.
Fixed-Price Contract
You sign for $X. You pay $X. No surprise change orders unless YOU change the scope. Your budget is protected.
In-House Everything
Architects, engineers, project managers, construction crews - all in-house. No subcontractor roulette. We control quality, accountability, and schedule.
Post-Build Support
10-year structural warranty, 1-year workmanship warranty, lifetime response. We answer the phone when you call, even after warranty expires.
Our Full-Service ADU Contractor Process
Let me walk you through exactly what happens when you work with us. I've done this hundreds of times, and I know where things go right—and where they can go wrong if you work with someone else.
The Discovery (30 days)
What happens: Free site assessment, feasibility report, city records check.
What you get: Clarity. You know if you can build, what you can build, and what it will cost.
Real example: Irvine client discovered an easement they didn't know about. We redesigned around it. Saved 4 months of rework.
Design & Plans (4-8 weeks)
What happens: In-house architecture, 3D renderings, material selection, engineering.
What you get: Beautiful, buildable plans that the city will approve.
Real example: Huntington Beach client wanted a rooftop deck. Our architect designed it to meet coastal height restrictions. City approved on first review.
Permitting (2-6 months depending on city)
What happens: Full-service submission, HOA coordination, utility coordination.
What you get: Permits without stress. We've built relationships with every city in OC.
Real example: Westminster client had permit in 3 months. Never visited city hall once. Neighbor was still waiting at 6 months.
Construction (4-8 months)
What happens: Fixed-price contract, weekly updates with photos, project manager on-site daily, quality control.
What you get: A construction site that's organized, clean, and on schedule.
Real example: Garden Grove client had ADU framed in 3 weeks. Neighbor with different builder still waiting for foundation.
Final Walkthrough & Handover (2 weeks)
What happens: Punch list, final inspection, warranty orientation.
What you get: A finished ADU you're proud of - and a team that will answer when you call.
Real example: Santa Ana client called 2 years later with minor plumbing issue. We sent someone next day. Fixed it. No charge.
The Difference: DIY vs. Full-Service ADU Contractor
Yes, working with a full-service ADU contractor costs more than hiring a general contractor and managing it yourself. Let's be honest about the math.
| Component | DIY Approach | Full-Service Approach (Us) |
|---|---|---|
| Architect | $8,000-$15,000 | One contract, one price $200k-$350k |
| Engineer | $2,000-$5,000 | |
| Permitting (you manage) | $5,000-$15,000 | |
| General contractor markup | $20,000-$50,000 | |
| Your time | 200+ hours (priceless) | |
| Total cost | $180,000-$300,000 | $200,000-$350,000 |
| Total time | 12-18 months | 10-14 months |
| Risk | Medium-High | Low (fixed price, we own problems) |
| Stress | High | Low |
The difference: 10-15% premium for full-service ADU contractor. For that premium, you get: 200 hours of your life back, no trips to city hall, no chasing architects, fixed price with no surprises, and someone who answers the phone.
The question isn't "is it cheaper?" It's "what's your time worth?"
What You're Really Buying
🏆 Peace of Mind
When you sign with a full-service ADU contractor, you're not buying walls and windows. You're not buying permits and inspections.
You're buying peace of mind.
Construction has surprises. The ground is wrong. Utility capacity isn't what the city said. A material is backordered.
With us, those surprises are our problem, not yours. We have contingency built into our budget. We have relationships to expedite materials. We have crews that can pivot when things change.
Accountability: When something goes wrong (and something will), who do you call? When you DIY, you call 5 different people who all blame each other. When you work with us, you call one number. We fix it.
That's what you're paying for.

Fixed price. No surprise change orders. If we underestimated something, that's our cost. If the city requires changes, we handle it at no extra cost. If YOU change your mind (move a wall, upgrade finishes), that's a change order. What we don't do: nickel-and-dime you with "surprise" costs that should have been anticipated.
From first call to move-in: 10-14 months. Site assessment: 2-4 weeks, design: 4-8 weeks, permitting: 3-7 months (city-dependent), construction: 4-8 months, final inspection: 2-4 weeks. Garden Grove fastest, Irvine slowest. Once permits are issued, we deliver on schedule.
No. You can go about your life. We provide a construction schedule upfront, give weekly updates with photos, coordinate access, and keep the site clean and secure. You're welcome to visit anytime, but you don't need to be there.
10-year structural warranty (foundation, framing, roof), 1-year workmanship warranty (finishes, fixtures, labor), manufacturer's warranty on appliances, and lifetime response—we answer when you call, even after warranty expires.
Yes. We specialize in HOA approvals. We've built in Irvine (Woodbridge, Northwood, Turtle Rock, Shady Canyon), Tustin (Tustin Ranch, Tustin Legacy), and Huntington Beach (Seacliff, Huntington Harbour). HOA adds 30-90 days. We manage it so you don't have to.
We don't ask for full payment upfront. Standard schedule: 10% deposit at contract signing, 25% at permit issuance, 25% at start of construction, 25% when framing complete, 15% at final walkthrough. Payments tied to progress, not arbitrary dates.
Yes. We'll connect you with recent clients in your area. We can provide phone numbers of 3-5 recent clients, written testimonials, and in-person visits (some clients are happy to show their ADU). Ask us: "Can I talk to someone in [your city]?"
You can, but it costs. We'll give you a change order with description, cost impact, and timeline impact. No change is made without your written approval. Tip: finalize decisions before construction starts—changes after framing cost 2-3x more.
Yes. We coordinate all utility connections: power (SCE), gas (SoCalGas), water (city water department), sewer (city sewer), and address registration (USPS, 911). Utility connection fees are pass-through costs—we don't mark them up.
We've never had a permit denied outright. If it happens, we review comments, revise plans at our cost (unless you requested the change), resubmit, and track through re-review. If your property truly cannot support an ADU, we'll tell you during the free site assessment.
Yes. We work with real estate investors on portfolio builds (multiple ADUs across properties), multi-unit properties (duplex, triplex conversions), and SB-9 lot splits with ADUs on each new lot. Benefits include volume pricing and coordinated scheduling.
Three things: True full-service (one team, one point of contact), local expertise (built in every OC city), and fixed-price certainty (no surprise change orders). We're not the cheapest—we're the contractor who will answer your call when something goes wrong.
