We've answered the questions Orange homeowners ask us most about accessory dwelling units. If you don't see your question here, call (877) 265-5812 and we'll talk it through.
Pricing & Cost FAQs
Most ADUs in Orange run between $180,000 and $320,000 for a detached unit, depending on size, site conditions, and finish level. Garage conversions typically land lower, while two-story units with premium finishes run higher. Your specific price depends on soil conditions, utility runs, and whether you choose a production builder like Abodu or a custom build. We give written line-item estimates so you see exactly where every dollar goes before you sign. Call (877) 265-5812 for a free estimate tailored to your property.
A garage conversion is usually the least expensive path to an ADU in Orange because the foundation, roof, and framing already exist. Converting an attached garage often costs less than a detached new build since utility connections are shorter. The tradeoff is size and ceiling height, which can limit layout options. We'll walk you through whether your garage is a good conversion candidate based on Orange's setback and parking rules. Call (877) 265-5812 and we'll assess your garage for free.
Our written estimates include permit fees, city inspection costs, and utility connections as separate line items, so nothing surprises you later. Orange requires specific fees for building permits, plan checks, and school district assessments that vary by project size. We pull all permits and handle inspections on your behalf. If you want to compare costs to other Orange ADU builders, ask for a line-item breakdown, not a lump sum. Call (877) 265-5812 for an estimate that accounts for everything.
It shouldn't, if you're working with a builder who does honest upfront pricing. We use fixed pricing with no change orders unless you request a change or the city requires something unanticipated, like foundation upgrades in expansive soil zones common in parts of Orange. Every estimate we write specifies what's included so you're comparing apples to apples. Call (877) 265-5812 and we'll put our pricing promise in writing.
Adding a bathroom to an Orange ADU typically runs $25,000 to $45,000 depending on fixtures, tile, and whether plumbing needs to run through new foundation work. A bathroom inside a garage conversion usually costs less because the slab can be cut and the waste line tied in closer. We source mid-range and premium fixtures from local supply houses in Orange to fit your budget. Call (877) 265-5812 for a bathroom-specific quote.
Service & Process FAQs
Plan on 3 to 6 months from design approval to final inspection for a detached ADU in Orange. Garage conversions run faster, often 8 to 12 weeks. City plan check times vary, but Orange's planning department has streamlined ADU reviews under state law. We handle the paperwork so you're not chasing approvals. Call (877) 265-5812 and we'll give you a realistic timeline for your specific property.
First we survey your Orange property and discuss your goals. Then we draft plans, submit to the city, and pull permits. Site work comes next: grading, foundation, framing, then mechanical rough-in. After inspections, we finish with drywall, paint, flooring, and fixtures. We walk you through a final orientation and hand over keys at the completion inspection. It's a straightforward process when someone's managing it for you. Call (877) 265-5812 to start your project.
Yes. We prepare and submit all plans, pull building permits, schedule inspections, and keep the city approval process moving. Orange has specific ADU ordinances covering setbacks, height limits, and parking that we navigate daily. You don't fill out city forms or chase status updates. Call (877) 265-5812 and we'll handle the entire permit process for your ADU.
Yes, and we've done it throughout Orange's hillier neighborhoods where grade changes require retaining walls, stepped foundations, or pier-and-beam construction. Sloped lots add cost because of excavation and engineering, but they often create walk-out lower levels that feel like full basements. We'll assess your lot's slope and give you honest options. Call (877) 265-5812 for a site evaluation.
Yes. Attached ADUs, sometimes called junior accessory dwelling units or JADUs, share a wall with the main house and often convert an existing bedroom or garage wing. Detached ADUs are standalone structures in the backyard with their own foundation. Orange allows both, and the right choice depends on your lot size, setbacks, and how you want to use the space. We'll evaluate your property and explain the tradeoffs. Call (877) 265-5812.
Both work in Orange, and the answer depends on your lot. Prefab companies like Abodu and Cover manufacture units off-site and crane them into place, which shortens on-site time. Custom building lets us match your home's architecture, work around tight Orange setbacks, and modify everything. We can build either path, and we'll price both so you can decide with real numbers. Call (877) 265-5812 to compare your options.
Brands & Parts FAQs
Yes. We install James Hardie fiber cement siding on many Orange ADUs because it holds up to Southern California sun and resists termites better than wood. It comes in finishes that match most existing Orange home styles, from Spanish revival to mid-century. It's a sensible choice for a structure that will sit in direct sun for decades. We can show you samples during your estimate. Call (877) 265-5812 to see what James Hardie looks like on an ADU.
We can work with a Tuff Shed shell if you've already purchased one, but most Orange homeowners choose to have us build from scratch because the permitting path is cleaner and the result is a conditioned living space, not a storage structure. ADUs need insulation, electrical, plumbing, and drywall that shed shells aren't designed for. We'll give you an honest comparison. Call (877) 265-5812 to talk through your Tuff Shed conversion question.
We spec James Hardie for siding, and we source windows, doors, flooring, and fixtures from suppliers we've trusted since 2013. For prefab shells, Abodu and Cover both build quality units that work in Orange when the lot suits them. Your finish selections depend on budget and whether the ADU is for family or renters. We guide you through selections without upselling. Call (877) 265-5812 and we'll start your finish list together.
Licensing & Insurance FAQs
Every professional working under our name is required to hold the license and insurance their state requires for residential construction.

Yes, we pull every permit the city of Orange requires and schedule each inspection. Unpermitted ADUs create title problems, insurance gaps, and resale troubles down the road. Orange code enforcement actively monitors unpermitted construction, so doing it right matters. We handle plan submittal, permit fees, and inspection scheduling for you. Call (877) 265-5812 to get permitted properly.

We're open Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed Saturdays.

Call us at (877) 265-5812 and describe the issue. We'll send someone from our Orange team to inspect and diagnose. Most post-construction issues are covered under our workmanship warranty, and we fix them at no charge when they are. If it's something outside our scope, we'll tell you honestly and point you to the right trade. Your ADU shouldn't have problems in year one, and if it does, we handle it.
Timing depends on our current Orange schedule and how quickly the city processes your permits.

We'll give you a written timeline before you commit. Call (877) 265-5812 to check current availability.
Warranty & Guarantees FAQs

Call (877) 265-5812 and we'll explain our warranty in full before you sign.
Yes. Every Orange ADU project starts with a written estimate that becomes a fixed-price contract once you approve it. We don't start work on handshakes or verbal agreements. Your contract spells out scope, materials, timeline, warranty, and payment schedule. You'll never wonder what something costs mid-project. Call (877) 265-5812 to get your estimate in writing.
Tell us during the final walkthrough and we'll fix it before we call the job complete. We walk every Orange ADU room by room with you and create a punch list of anything that needs attention.
