Get your free estimateFast, Reliable Home Addition Contractor Across Coto de Caza
Adding space to a Coto de Caza home is rarely a simple bolt-on job. The guard-gated community, the equestrian lots, the custom builds from the 1970s onward, and the dual approval process with the CZ Master Association and the county all layer onto what should be a straightforward room addition. We handle the full scope: Home Addition Contractor work that starts with a written price, continues with a real arrival window, and ends with a written guarantee. If you’re planning a bedroom addition, sunroom, or bump-out near the Coto de Caza Golf & Racquet Club, call (350) 203-6060 and we’ll walk the lot with you before quoting.
We’re Lodgewick ADU Orange County. We build more than ADUs. We build the additions Coto de Caza homeowners actually need: second story additions, sunrooms, garage additions, and the kind of bump-outs that make a 1980s Mediterranean feel like it was built for now. The first thing we tell every homeowner here is the same: no price until we’ve looked behind the drywall. We’ll explain why below.
Why Lodgewick ADU Orange County Is Coto de Caza’s Preferred Home Addition Contractor Company

Coto de Caza is our backyard. We know what a CZ Master Association submittal looks like, we know how long the county review queue runs this quarter, and we know that the gate at the Coto de Caza Drive entrance doesn’t wave in a flatbed just because you have a permit number. Our crews pre-coordinate every delivery and every inspection. That sounds like a small thing. It’s not. It’s the difference between a framing inspection passing on the first visit and a crew standing idle for three days waiting on a re-schedule.
Russ Delmar leads the team, and he’s the one you’ll talk to about your addition. The work itself runs on The Kingswell Guarantee: a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee on every project. In Coto de Caza specifically, we also write gate-access coordination and HOA submittal support into the contract. Most contractors treat those as your problem. We treat them as part of the build.
Written Price, Written Guarantee, Written Everything
Before we drive a single nail on a Coto de Caza addition, you get a written price. Not a ballpark. Not an estimate with a wink. A line-item price. If we open a wall and find something the inspection missed, you get a written change order with a price before we touch another stud. You approve it, or you don’t. There’s no door-knock price increase, ever, on any project.
Bedroom Addition Contractor in Coto de Caza
A Bedroom Addition Contractor in Coto de Caza does more than frame four walls and call it a room. On the estate lots here, a bedroom addition usually means tying into an existing structure built decades ago, matching stucco texture and tile roof profile, and coordinating with both the CZ Master Association and the county on setbacks, height limits, and fire-resistant materials. A standard ground-floor bedroom addition in Coto de Caza runs roughly $180 – $320 per square foot, so a 250-square-foot room lands around $45,000 – $80,000 depending on foundation work, finish level, and what the permit triggers. Second-story additions run higher because of the engineering and shear-wall upgrades that older Coto de Caza framing almost always requires.
Working With Existing Coto de Caza Framing
Most Coto de Caza homes were built before current seismic codes. That means the existing framing may not carry the new roof load, and the county will require a shear-wall upgrade before it signs off. We design for that from the start, not as a surprise later.
What the Permit Triggers
Opening a wall for a bedroom addition in Coto de Caza commonly triggers AFCI circuit requirements, smoke and CO detector upgrades in the adjacent existing spaces, and sometimes full rewire of the branch circuits you’re tying into. We put allowance credits in the written price so you know the range before we open anything.
Sunroom Addition in Coto de Caza

A Sunroom Addition in Coto de Caza has to do two things that sunrooms in coastal towns never worry about: keep the heat out in the summer and resist ember intrusion during fire season. The community sits in a high fire hazard zone with limited access routes. That’s not an abstract warning. The CZ Master Association and the county both care about fire-resistant glazing, non-combustible roofing, and defensible-space clearance. A sunroom here typically runs $220 – $400 per square foot. A 200-square-foot sunroom on a slab foundation usually falls between $44,000 and $80,000. The range widens when you’re tying into an existing deck or adding electrical for climate control.
Glass, Orientation, and the Coto de Caza Sun
Hot, dry summers mean we orient sunrooms to capture morning light and block afternoon heat. Low-E glass and proper roof overhangs aren’t upgrades here. They’re the difference between a room you enjoy and a glass oven by August.
Fire-Resistant Materials, Not an Afterthought
We spec Class A roofing, tempered glass with ember-resistant screens where required, and stucco or fiber-cement siding to match the existing home. The Coto de Caza permit office will ask. We have the answers in the submittal before the first inspection.
Trusted Brands We Service in Coto de Caza
Some Coto de Caza homeowners want a traditional stick-built addition. Others want a prefab ADU or sunroom shell that arrives on a truck and goes up in weeks. We work with both, and we know the brands that hold up in this climate. We’ve built with Cover and Dvele prefab systems, and we’ve specified Boxabl units where the lot and HOA allow. The advantage isn’t a brand name. It’s that we know which system clears CZ Master Association design review, which one handles the Coto de Caza fire zone requirements, and which one fits through the community’s gate access without special permits. We stock the common trim, flashing, and tie-in materials locally so a prefab build doesn’t stall waiting on a part.
Common Home Addition Contractor Problems We See in Coto de Caza Homes
- Original aluminum wiring hiding behind drywall. On a 1980s Mediterranean estate near the Coto de Caza Golf & Racquet Club, we opened a wall for a bedroom addition and found exactly that, along with termite-damaged framing. We stopped, scoped it, and wrote a change order before touching another stud.
- Termite-eaten or undersized framing. The lots here are old enough that drywood termites have had decades to work. Adding a second story on framing that won’t carry the load means an engineering fix, not just extra wood.
- Failed waterproofing from original construction. Stucco and tile roofs last a long time, but flashing at the intersection of a new addition and an old wall is where Coto de Caza additions leak. We inspect the tie-in points before quoting, and we write the waterproofing scope into the contract.
- Gate access delays that stall deliveries and inspections. Every material delivery and every inspector has to clear the Coto de Caza gate. If the access request isn’t submitted early, the whole schedule slips. We pre-coordinate every entry.

FAQs About Home Addition Contractor in Coto de Caza
Not always. But it commonly triggers AFCI circuit requirements and smoke or CO detector upgrades on the circuits you’re tying into. If the existing wiring is aluminum or cloth-jacketed, the county may require rewiring the exposed branch circuits before the final inspection. We scope this during the pre-construction inspection and write an allowance credit into your contract, so the range is known before the wall opens. Call (350) 203-6060 and we’ll walk you through what applies to your home.
We prepare the submittal for the CZ Master Association first, because their design review covers aesthetics, setbacks, roof profiles, and fire-resistant material choices. Then we file with Orange County for the building permit. We run both tracks in parallel when we can, and we coordinate gate access for every inspection. The dual approval adds time. Planning for it from day one keeps the build on schedule. A free estimate includes a timeline for both approvals.
An engineer checks the existing framing before we quote. If the framing won’t carry the new load, we write a shear-wall and reinforcement scope into the contract with a price range. The cost depends on how much of the existing wall has to be opened and whether the foundation needs added support. This is exactly why we inspect before quoting in Coto de Caza, not after the wall is open. Call (350) 203-6060 for a written price that includes the engineering.
Yes. We spec Class A roofing, tempered glass with ember-resistant screens, and non-combustible siding to match the existing home. The Coto de Caza permit office and the CZ Master Association both review for fire zone compliance. Our submittals include those details up front, so the sunroom passes design review and building inspection without rework. A standard sunroom here runs $220 – $400 per square foot.
You get a written change order with a line-item price before any corrective work starts. If the original flashing at the wall intersection has failed, we price the repair, the new waterproofing membrane, and any stucco or tile repair needed to match. You approve it first. We don’t proceed on verbal approval. That’s the Kingswell way, and it’s in writing on every Coto de Caza project. Call (350) 203-6060 and we’ll put the first number in front of you free.
