Seedling ADU Builders plans and builds accessory dwelling units, garage conversions, and home additions across Austin. Most projects involve navigating the city’s impervious cover limits, heritage tree protections, and older central-Austin lots that measure 5,000 to 7,000 square feet, so careful siting matters as much as square footage. Austin’s hot, humid summers also push us toward high-efficiency cooling, serious insulation, and drainage details that hold up under flash-flood conditions. If you’re weighing an ADU on your lot, call (254) 615-3842 for a free estimate.
Why Austin Homes Are Different
Central Austin neighborhoods like Hyde Park and Travis Heights are full of 1940s and 1950s bungalows on tight lots, while Allandale and Crestview lean toward 1960s and 1970s ranch homes. Outskirts have newer 1990s and 2000s tract housing with more room to work. That mix changes how we plan every project. A detached ADU behind a bungalow in Travis Heights often lands within a few feet of a protected live oak, so we bring in an arborist and design the foundation to avoid cutting major roots. A single tree can dictate the entire footprint of the unit.
Austin’s McMansion Ordinance and recent ADU-friendly code updates have made detached units realistic in central neighborhoods, but impervious cover limits still cap how much of a lot can be covered by buildings and paving. Drainage is the other constant: flash flooding in low-lying areas means we grade carefully and size downspouts and drains for the worst storm, not the average one. UV exposure is relentless, so exterior materials need to hold color and structure through years of direct sun, and air conditioning has to be sized for July and August humidity, not spring.
Our Main Austin Services
Austin homeowners call us most often about two things: adding living space to an existing home and converting underused square footage into something livable. Each service has its own detailed Austin page below.
Home Addition Contractor in Austin
A home addition in Austin usually means working around an occupied house with kids and pets, which is where the Cedarwell Care Promise shows up daily: shoe covers, drop cloths, pet-safe products where there’s a choice, and a photo of the clean-up before the crew leaves. On older central-Austin homes, additions often require tying new framing and rooflines into existing 1940s or 1950s construction, and we plan that interface before the first cut. For the full scope of how we handle Austin additions, see Home Addition Contractor in Austin.
Garage Conversion Contractor in Austin
Garage conversions in Austin are a practical path to a rental unit or extra bedroom without expanding the home’s footprint, which helps with impervious cover limits. Existing concrete slabs work well here, but many older garages in Allandale and Crestview need new electrical, insulation, and ceiling height adjustments to meet code. We also address air sealing and ductwork so the converted space handles Austin summers without running endlessly. The step-by-step approach is on Garage Conversion Contractor in Austin.
ADU Builders in Austin
Backyard ADUs in Austin are often shaped by setbacks, tree protection zones, and utility routing before we talk floor plans. We work with homeowners who want a prefab unit placed on a prepared foundation and with those who prefer a site-built design tailored to an irregular lot. Either way, every Austin ADU receives a written price before work starts and is backed by the 365-Day Done Right Promise. The full process, including how we handle protected trees and drainage, lives on ADU Builders in Austin.

FAQs About ADU Company in Austin
Plan review timing in Austin varies by project complexity and current city workload, but most ADU and garage conversion permits clear within six to twelve weeks after submission. Projects touching heritage trees or drainage variances can extend that timeline. We handle the paperwork and keep you updated at each step. Call (254) 615-3842 if you want an exact read on your lot.
Some Austin neighborhoods have deed restrictions or HOA rules that limit ADUs, rental use, or exterior finishes even when the city permits the structure. We review HOA documents before design begins so you’re not surprised later. A written proposal includes everything we find.
