Pricing & Cost FAQs
A detached ADU in Orange County typically runs $180,000 to $350,000, while garage conversions land between $90,000 and $160,000. What actually moves the number: the condition of your existing structure, whether the lot slopes, how far the utilities have to travel, and the finish level you choose. Coastal cities like Laguna Niguel and San Juan Capistrano often carry slightly higher costs due to foundation requirements and tighter setback rules. Lodgewick ADU Orange County gives you a written price before any work starts, so the number you approve is the number you pay. Call (350) 203-6060 for a free estimate.
A garage conversion is almost always the least expensive path because the foundation, framing and roof already exist. You're paying for plumbing, electrical, insulation, drywall and finishes rather than starting from bare dirt. The trade-off is ceiling height and layout constraints, older garages in Fullerton and Anaheim often have low plates and non-conforming footings. If you're working with a tight budget, converting beats building new every time. We'll walk through the numbers on both options during your free estimate at (350) 203-6060.
No. Estimates are free, and they come as a written line-item breakdown, not a vague number in a text. You'll see exactly what the materials, labor, permits and site work cost before you commit to anything. Lodgewick ADU Orange County works to the Kingswell Guarantee: a written price before any work starts. Call (350) 203-6060 to schedule yours.
It shouldn't, and if it does, you'll know why before it happens. Fixed pricing with no change orders is how we work. The only things that legitimately move a price mid-job are conditions nobody can see until the walls come open: rotted framing, inadequate footings, asbestos, or the owner asking for upgraded finishes. Orange County is full of 1960s tract homes in Lake Forest and Midway City where the original slab isn't always what the plans assumed. We put the guarantee in writing, and that includes explaining any price adjustment before work proceeds. Call (350) 203-6060 for a written quote.
Plan on $90,000 to $160,000 for a full garage conversion in Orange County, depending on whether you're adding a bathroom, how much electrical work the panel needs, and whether the slab requires leveling. Anaheim and Santa Ana garages from the 1950s and 60s often need seismic retrofitting that newer structures don't. A straightforward studio conversion without plumbing runs toward the lower end; a one-bedroom unit with a full bath lands higher. We'll give you the exact range for your specific garage after a site visit. Call (350) 203-6060.
Yes, most homeowners do. Common options include HELOCs, cash-out refinances, construction loans and California's CalHFA ADU grant program, which covers pre-construction costs like plans and permits. Some Orange County cities also participate in local assistance programs. What you'll need from us is a firm written estimate, lenders won't underwrite a vague number. We provide detailed cost breakdowns for exactly that purpose. Call (350) 203-6060 to get the paperwork started.
Service & Process FAQs
Most ADUs in Orange County take 9 to 14 months from initial consultation to final inspection. About 2 to 4 months goes to design, engineering and city permits, then 6 to 10 months of construction. Cities move at different speeds: Costa Mesa and Fullerton are generally faster, while coastal jurisdictions like Laguna Niguel and San Juan Capistrano can take longer on design review. The Kingswell Way is simple: we show up in the window we gave. Call (350) 203-6060 and we'll map out a realistic timeline for your lot.
Yes, every ADU in Orange County requires a building permit. There's no such thing as an unpermitted ADU that will pass a future appraisal or code enforcement check. Unpermitted work also won't qualify for financing and typically gets flagged when you sell. The permit process includes plans, structural review, and inspections at set stages. We pull the permits, coordinate with the city and pass the inspections before you write the final check. Call (350) 203-6060 and we'll handle it from day one.
It starts with a free on-site visit to look at your lot, setbacks and existing structures. Then we provide a written estimate, you approve it, and we move into plans, engineering and permit submission. Once the city approves, construction begins: site work, foundation or conversion framing, rough plumbing and electrical, drywall, finishes, and inspections. You'll get a clear schedule before we start. The final walkthrough with you happens before we consider the job done. Call (350) 203-6060 to start.
Yes, but expect different foundation work than a flat lot. Sloped lots in North Tustin and Coto de Caza frequently require stepped footings, retaining walls or pier-and-grade-beam systems instead of a simple slab. That adds cost and engineering time, but it's standard work for an experienced ADU builder. What matters is the geotech report and a structural engineer who knows Orange County soil conditions, which vary from sandy coastal fill to hard clay inland. Call (350) 203-6060 for a site evaluation.
California state law allows an ADU up to 1,200 square feet regardless of local zoning, though setback and lot-coverage rules still apply. Most Orange County homeowners build between 500 and 1,000 square feet. A one-bedroom unit typically runs 500 to 700 square feet; a two-bedroom runs 800 to 1,000. Local rules in cities like Laguna Hills and Fullerton may add design review requirements but can't reduce the statewide size allowance. Call (350) 203-6060 to see what fits on your lot.
Yes. Lodgewick ADU Orange County manages the full project: design, structural engineering, permit submittal, construction and final inspection. You're not coordinating three different companies. If something fails inspection, we fix it and schedule the re-inspection. That's what The Kingswell Guarantee is for: a written promise covering the work. Call (350) 203-6060 to discuss your project.
Brands & Parts FAQs
We primarily build site-built ADUs, which give you full control over layout and finishes, and they're easier to permit in most Orange County cities. Prefab manufacturers like Abodu and Cover have models designed for California lots, and in some cases they can cut construction time significantly. The trade-off is less design flexibility and factory lead times that shift. We'll talk through which approach makes sense for your lot and budget. Call (350) 203-6060 for an honest comparison.
The prefab brands we hear about most from Orange County homeowners are Abodu, Cover and Dvele. Abodu focuses on quick-turn detached units, Cover builds panelized custom designs, and Dvele targets high-performance homes with smart-home integration. Each has a different price point and timeline. For site-built work, the quality comes down to the builder's process and warranty more than a brand name. That's why we put The Kingswell Guarantee in writing. Call (350) 203-6060 to compare options.
We specify materials based on what performs best in Orange County's climate and building codes: engineered lumber for termite resistance near the coast, high-quality windows suited to sunny inland cities, and plumbing fixtures built for our water quality. We don't lock you into one manufacturer. If a homeowner has a preference, we'll price it and discuss the trade-offs. The Kingswell Guarantee covers the labor and installation regardless of the brand. Call (350) 203-6060 for specifics.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance their state requires, and our local Orange County branch is led by Russ Delmar, who has built his career around exactly that standard. Ask any contractor for their license number and verify it with the California Contractors State License Board. Legitimate builders expect the question. Call (350) 203-6060 and we'll walk you through our credentials.
Yes, we pull every permit for every ADU we build. That includes building, electrical, plumbing and mechanical permits, plus any city-specific approvals like design review in Laguna Beach or historic district checks in parts of Fullerton. A licensed contractor who suggests skipping permits is telling you something important about how they run their business. We put the permits in writing and pass every inspection. Call (350) 203-6060 to ask about your city's process.
Every pro working under our name is required to carry the bonding and insurance their state requires. For homeowners, bonding protects you if the contractor fails to complete the job or meet the contract terms. Before you sign with any ADU builder in Orange County, ask for their bond and verify it. It's a standard question, and the answer should come without hesitation. Call (350) 203-6060 with any credential questions.
Emergency & Response FAQs
You call us, and we show up. Our hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM, and a live coordinator answers the phone. If it's a safety issue like exposed wiring or standing water, we'll get someone out right away during those hours. The Kingswell Guarantee says it plainly: if the work fails inside the guarantee period, we come back and fix it at no charge. Call (350) 203-6060.
Yes, and it happens more often than you'd think in Orange County. The typical situation: a homeowner paid a deposit, got a half-finished shell, and the contractor stopped answering calls. We can assess what's done, what's salvageable and what needs to be torn out, then give you a written price to finish it. Permits may need to be transferred or refiled depending on how far along the job is. Call (350) 203-6060 and we'll come look.
If something fails and it's unsafe, water-related, or a code issue, we'll treat it as urgent and schedule it fast within our business hours, Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. A broken water line, a failed electrical circuit or a leak around a window are all calls we take seriously. Call (350) 203-6060 and a live coordinator will connect you with our local team.
Warranty & Guarantees FAQs
Every ADU we build is covered by The Kingswell Guarantee: a written promise that if the work fails inside the guarantee period, we come back and fix it at no charge. The specific coverage terms are spelled out in your contract before construction starts, never after. That includes workmanship on framing, roofing, plumbing, electrical and finishes. Russ Delmar has led this Orange County branch with that guarantee at the center of every job. Call (350) 203-6060 with questions.
The Kingswell Guarantee covers four promises: a written price before any work starts, a real arrival window, a clean job site and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. Every Kingswell location works to the same four promises, and each location is independently owned and operated. That's why we say the price before the work, and leave the place cleaner than we found it. Call (350) 203-6060 for details.
Tell us during the final walkthrough and we'll make it right before we consider the job complete. The Kingswell Way is explicit: put the guarantee in writing, and come back if it fails. We don't disappear after the final check clears. Orange County homeowners in Costa Mesa and Anaheim who have worked with us know they can pick up the phone months later. Call (350) 203-6060 and talk to our team.
DIY vs. Pro FAQs
Hiring a licensed contractor is the only realistic option for most people. Acting as your own general contractor is legal in California if you occupy the home and do some work yourself, but you're taking on permit coordination, scheduling, code knowledge and liability. Orange County inspectors hold owner-builders to the same standard as professionals, and they don't offer extra patience. Most owner-builder projects stall because the sequencing breaks down. We've fixed enough half-built DIY ADUs to know. Call (350) 203-6060 instead.
You can, but you shouldn't unless you have real construction experience. Garage conversions involve electrical panel upgrades, plumbing rough-ins, structural modifications and fire-safety requirements that Orange County inspectors enforce strictly. A mistake in the slab plumbing means tearing out fresh concrete. What you save in labor you often lose in rework and permit violations. Let a pro handle it. Call (350) 203-6060 for a free estimate on your conversion.
