Fielding ADU Builders handles ADUs, garage conversions, and room additions in Manor, TX. Most Manor homes we work on are 2000s-era production builds on large lots, and the two things that change the job here more than anything are the Blackland Prairie clay under the slab and the septic systems that serve much of the city’s expanding ETJ. If you’re planning an ADU in Manor, call (361) 309-9568 and we’ll walk you through what your specific lot will actually require.
Why Manor Homes Are Different
Manor’s rapid ETJ expansion means many properties are on septic systems, not city sewer. Adding an ADU often triggers new OSSF (on-site sewage facility) requirements and lot-specific soil testing under Travis County oversight. That’s a hurdle most neighboring cities’ ADU builders rarely face to the same degree, and it’s one we plan for from the first site visit, not after the permit application bounces back.
The soil itself is the second piece. Blackland Prairie clay expands and contracts through Manor’s hot, dry summers and occasional heavy rains. A detached ADU on an under-engineered slab will move. We specify foundation designs for Manor’s clay specifically, and we lean toward ductless mini-split heat pumps for detached units because they handle 100°F days efficiently and don’t require ductwork through a small footprint.
Housing stock varies enough that there’s no one-size-fits-all approach. Older ranch-style homes near downtown Manor sit on different foundations than the slab-on-grade production homes in Presidential Meadows and ShadowGlen. Newer builds with PEX plumbing and standard 200A panels make some ADU connections easier. Lot size and HOA restrictions vary widely across the city, and we check both before we quote.
Our Main Manor Services
These are the three jobs Manor homeowners call us about most. Each has its own dedicated Manor page with pricing, process details, and permit specifics.
Room Addition Contractor in Manor
A room addition in Manor usually means tying into a slab-on-grade home while matching the roof line and siding of the original build. HOA restrictions in subdivisions like Presidential Meadows can dictate roofline pitch, exterior materials, and setback placement before the city ever looks at the plans. We handle the HOA submittal as part of the job. Room Addition Contractor in Manor
Garage Conversion Contractor in Manor
Garage conversions in Manor often make sense because the slab, roof, and framing already exist, which keeps the structural scope smaller than a ground-up ADU. The catch is that many Manor garages were never insulated or wired for living space, so HVAC, electrical, and floor leveling typically make up a good portion of the budget.

ADU Builders in Manor
Detached ADUs in Manor face the septic and soil conditions described above, plus plat restrictions in some subdivisions that prohibit detached units outright. When a detached ADU isn’t allowed, an attached conversion or garage ADU often is. We match the build method, prefab or conventional, to your lot and your HOA’s rules. ADU Builders in Manor

What pushes price up in Manor more than anything is the septic work. If your ETJ property needs an OSSF replacement or expansion to support the added bedroom and bath, that line item can add $10,000 to $30,000 before construction starts. The second driver is foundation work on older ranch homes near downtown, where the clay has already done damage over decades. Every Fielding ADU Builders quote is a written price handed to you before any work starts, and the number you approve is the number on the final invoice.

FAQs About ADU Company in Manor
Permitting in Manor typically takes 6 to 12 weeks for a standard ADU, but septic review under Travis County oversight can add another 4 to 8 weeks if your property is in the ETJ. We submit the permit package as one complete set, which reduces back-and-forth. Call (361) 309-9568 and we’ll give you a realistic timeline for your specific lot.
Some do and some don’t. Presidential Meadows and ShadowGlen both have recorded plat restrictions that prohibit detached ADUs in many sections, which means attached conversions or a formal HOA variance are required before any foundation work. We pull the plat and HOA covenants before we quote, so you don’t pay for plans that get rejected.

What Manor Customers Say
"Built a detached ADU behind our house. The builder is a veteran and runs the site like a platoon: schedule posted, crew on time, everything labeled. Finished within a few days of the date."
- Ken W."Good addition. Electrical inspection delayed a week, which was the county, but the build is great."
- Eva K."Room addition over the back patio. Framing is square, windows are tight, and the roofline matches."
- Danny L.
