Accessory Dwelling Units
Smart Living Solutions Start with an ADU
Need more space? Whether it's for family, rentals, or work, an Accessory Dwelling Unit (ADU) gives you more options right at home. Homeowners across Orange County are turning garages, side yards, and detached spaces into full living areas that work harder for them. It’s a smart way to increase space and value without buying or moving.
At SunCoast Remodeling, we plan and build custom ADUs that blend with your home and serve your needs. Detached or attached, new construction or conversion, we bring ideas to life with practical design and solid craftsmanship. We guide you from the first drawing all the way to the final walkthrough, so your new living space is right, inside and out.
The Right ADU Style for Your Property
There’s no one-size answer. You have several ways to add an ADU depending on your space, goals, and layout. We help you sort through choices and create a plan that fits where you live.
Here are the most common ADU types we build:
Detached ADUs
Standalone units built in the backyard or side yard.
Attached ADUs
Extensions that share at least one wall with your main home.
Garage Conversions
Turn unused garages into a full living area.
Each design can include kitchens, bathrooms, separate entrances, or flexible open layouts. Whether it’s a full apartment or a small studio, we make sure the ADU works with your daily routine and fits well on your lot. Every unit is built to match your home’s style, siding, roof, and proportions.
What You Need to Build an ADU in Orange County
ADU rules vary from city to city, but most parts of Orange County follow similar basic codes. We’ll walk you through the local requirements and make sure every rule is met. It’s more than design; it’s about making approvals stress-free.
Local ADU planning often involves:
Property setback rules (the distance from edges of your lot)
Height and square footage limits
Parking needs, depending on your city
Permit approval for structure, plumbing, and electric
Connection plans for water, sewer, and power
From Mission Viejo to Huntington Beach, we’ve worked with the city agencies that review and approve ADU plans. Instead of figuring it out alone, work with builders who know how to move things forward. We handle plan sets, code checks, and submissions so you’re not held up by red tape.
Our Process for Building Your ADU
Every ADU starts with a careful plan. We look at your property, ask about your goals, and figure out what makes the most sense. Then we work through each step with care.
Here’s how our ADU process works:
1. Consultation
We meet at your site, talk about space, layout, and intended use.
2. Design
We draw up plans and place plumbing, electric, heating, and access points.
3. Permits
We prepare drawings and file with the city or county.
4. Build
We begin construction, keep to the schedule, and stay organized from start to finish.
5. Finish
Once work is complete, we double check everything, paint, floors, fixtures, and walk through the final product with you.
ADU jobs can take between 3 to 5 months depending on design, complexity, and city response times. We keep you updated and make sure the work stays on track so your new unit is move-in ready, right when you need it.

FAQs About ADUs
How much does an ADU cost?
That depends on size, layout, and site prep. Detached ADUs range between $150,000 and $350,000. Conversions cost less but vary based on plumbing and structure.
Can I build an ADU on a small lot?
Most lots can support an ADU, but the layout matters. We’ll look at your property lines and setbacks before giving a clear answer.
Do I need new utility connections?
Not always. Garage conversions and attached ADUs can often tie into existing service. For detached units, we usually plan new or extended connections depending on use.
Can ADUs be rented legally?
Yes. Most cities in Orange County allow long-term rentals of ADUs. Some allow short-term rental, but it depends where you live. We help you check local rules for use.
