Add a Guest House, Rental,
or In-Law Suite —
Without the Guesswork
Licensed Austin ADU contractors who design, permit, and build your accessory dwelling unit from start to finish — one team, one price, no surprises.
Why Austin Homeowners
Are Adding ADUs Right Now
Austin rental rates for ADUs run $1,200–$2,500/month. Your backyard is sitting idle while that income could pay your mortgage or fund retirement.
Aging parents, adult kids, or a live-in caretaker need their own space. An ADU gives them independence without the cost and distance of a separate property.
You’ve called contractors and gotten ballparks ranging $50k apart. Without a full design, nobody can give you a real number — we fix that at the first consultation.
Austin zoning rules, setbacks, utility connections, HOA restrictions — it’s a maze. We assess your property at the first visit and tell you exactly what’s possible.
Working from the guest room is a stopgap. A dedicated ADU gives you a professional, quiet, separate workspace that also adds real resale value to your property.
Austin ADUs add $150k–$300k in appraised value on average — often more than the cost to build. Your neighbors are doing it. Your property is falling behind.
One Team.
Design to Keys in Hand.
Most contractors hand you to a separate architect for design, then start over for permits. We do everything — architectural drawings, permit submission, and construction — one team, one contract.
Austin ADU permitting through the Development Services Dept is complex and slow. We’ve done it dozens of times — we know the process, the reviewers, and how to avoid delays.
ADU projects are notorious for cost overruns with other contractors. We price after a full site assessment and design scope — what we quote is what you pay.
Full Texas General Contractor license, general liability, and workers’ comp. Proof of insurance provided before any work begins. You’re protected from day one.
ADU projects run 6–12 months. We send weekly photo updates, keep you on a live project timeline, and answer every question. You’ll always know exactly where your project stands.
Every Type of ADU,
Built for Austin Properties
Every project starts with a free site consultation. We assess your lot, HOA rules, zoning, setbacks, and utility access before recommending the right ADU type for your property.
A fully independent structure in your backyard — own entrance, own utilities, own address. The most popular ADU type in Austin. Up to 1,100 sq ft, 1–2 bedrooms.
Convert your existing detached or attached garage into a fully permitted ADU. Lower cost than new construction. Typically 400–700 sq ft, perfect for studio or 1BR use.
An addition connected to your main home with a private entrance and full living facilities. Ideal for in-law arrangements. Shares your main home’s foundation and exterior walls.
A compact, efficient single-room ADU optimized for rental income, home office, or artist studio use. Typically 300–500 sq ft. Lower build cost, fastest permitting timeline.
Maximize rental income or accommodate a family. A 2BR ADU in Austin commands $1,800–$2,500/month in rent. Requires a larger lot but delivers the highest return per square foot.
Full architectural drawings, structural engineering, and permit submission for homeowners who already have a builder. Get your permit-ready plans without committing to full construction.
From First Visit to
Keys in Hand
An ADU is a major project. We make it straightforward with four clear phases — and we manage every single one of them so you don’t have to.
We assess your lot, HOA, zoning setbacks, utility connections, and feasibility. You leave knowing exactly what’s possible on your property.
Our in-house architects produce full drawings and submit to the City of Austin. We track the permit until approval — you don’t lift a finger.
Our licensed crew builds from foundation to finish. Weekly photo updates and a live schedule keep you fully informed throughout the build.
Final inspection, city sign-off, and a full walkthrough together. Your ADU is ready to occupy, rent, or list the day we hand you the keys.

Austin Homeowners Who
Added an ADU with Us
Real names, real ADU projects, real results from Austin families who trusted Together Exterior & Outdoor Remodeling.
“We added a 480 sq ft detached ADU to our Cedar Park property. It’s now rented for $1,450/month and covers most of our mortgage. Together Exterior handled design, permits, and construction — we literally just showed up for the final walkthrough. Unbelievable experience.”
“My mother-in-law needed her own space but we couldn’t afford a separate house in Austin. Together Exterior converted our detached garage into a beautiful 1BR in-law suite in 5 months. She has her own entrance, kitchen, and laundry. It’s been life-changing for our whole family.”
“I was terrified about Austin permitting — I’d heard horror stories from neighbors who were stuck for 18 months. Together Exterior got our permit approved in 11 weeks. Construction was tight and on schedule. The final product is stunning. I wish I’d done this years ago.”
