Pflugerville is not Austin. That single fact shapes more ADU outcomes here than any design trend or material choice, and we’ll come back to it throughout this page. Our team coordinates with the city’s Development Services staff regularly, and we know which subdivisions in Blackhawk, Stone Hill, and Falcon Pointe have CC&Rs that predate ADU legalization. That local familiarity is the difference between a permit set that sails through review and one that gets stuck for three extra months.

Why Ellery ADU Studio Is Pflugerville’s Preferred New Detached ADU Company

We approach Pflugerville projects the way the city’s own review staff does: paperwork first, then concrete. Since 2015, Ellery ADU Studio has designed, permitted, and built more than 900 ADUs, and every one of those started with a written price before any design work began. That’s Haven Clause 1, and it’s not a marketing phrase. It’s the first line in our contract.

Our New Detached ADU team has worked through Pflugerville’s UDC review process enough times to know which of our drawings the city will scrutinize and which submittal omissions trigger the most common re-review requests. Homeowners across Pflugerville consistently tell us the same thing: they expected Austin’s relaxed ADU rules and got Pflugerville’s own code instead. We close that gap before you spend a dollar on drawings.

We also bring something most design-build studios don’t: the documentation. Every visit includes a written photo record. Every permit set is an actual permit set, not a napkin sketch. Every finished ADU carries a 365-Day Done Right Promise in writing. Under Clause 5 (No Surprises), the scope is locked at signing. No door-side upsells. No “we discovered something” surprises that add $20,000 mid-project.

Nadia Ellery, who runs the studio, has structured every engagement around a simple principle: the permit set is the product. The construction is what delivers it. When both come from the same contract, there’s no designer-versus-builder blame loop. When they come from different companies, you spend your fall playing referee. We’re built to avoid that entirely.

Our New Detached ADU Services in Pflugerville

Custom Built ADU

A custom detached ADU in Pflugerville gives you control over floor plan, materials, and how the unit sits on your lot. Most of our custom builds here range from a 400-square-foot studio to a 750-square-foot one-bedroom with a full kitchen, and they run $210,000-$290,000 depending on finish level and slab requirements. We design the unit to your HOA’s architectural guidelines from day one, not as a retrofit after your design gets rejected by the review committee. That sequencing saves real calendar time.

Prefab ADU Installation

Pflugerville lots with tighter rear yards often lend themselves to prefab systems from Abodu, Cover, or Dvele. These units arrive as factory-built modules, and our team handles the full site package: slab or pier foundation, utility hookups, permit coordination, and final trim-out. A prefab ADU installation in Pflugerville typically runs $185,000-$240,000, including the factory build, transport, site work, and our written warranty. The slab work still matters here. Black clay doesn’t care whether your walls arrived on a truck or went up stick by stick.

Studio ADU

The studio is the most common detached ADU we build in Pflugerville, and for good reason. A 400-500 square foot studio with a bathroom, wet bar or kitchenette, and a separate entrance typically runs $185,000-$225,000. In HOA-governed subdivisions where CC&Rs ban second kitchens, the studio with a wet bar is the workaround that actually gets approved. We’ve filed this exact configuration in Blackhawk more than once. It clears architectural review because it reads as a guest suite, not a rental unit.

Modular ADU

Modular ADUs from brands like Mighty Buildings give Pflugerville homeowners a middle path between site-built and traditional prefab. We coordinate the factory order, prepare the site, and complete the on-site assembly under the same single contract. Modular units here typically run $195,000-$260,000. The planning sequence doesn’t change: HOA review first, city permit second, foundation third. We file the architectural packet before we order the modules, which prevents the worst-case scenario of a home delivered to a lot with no completed slab.

Trusted Brands We Service in Pflugerville

We specify and coordinate factory-built ADU systems from Abodu, Cover, Dvele, and Mighty Buildings, and our team has completed installation and finishing work on all four in the Pflugerville area. For homeowners who have already purchased a unit from one of these brands, we provide the full site package and construction management under our written price guarantee. For those still comparing systems, we’ll give you an honest read on which brand’s engineering fits Pflugerville’s soil and setback constraints. Not every factory unit works on every lot. We’ll tell you before you buy, not after.

Common New Detached ADU Problems We See in Pflugerville Homes

• CC&R prohibition on second kitchens. The most common project-killer in Blackhawk and Stone Hill. HOAs drafted these covenants before ADU legalization, and a blanket ban on accessory kitchens survives in many of them. We review CC&Rs before design dollars are spent, then shape the unit to comply (example: a wet bar instead of a stovetop).
• Expansive black clay under the slab. Pflugerville sits on the same clay belt that runs through Travis and Williamson counties. A standard 4-inch monolithic slab without post-tension reinforcement or thickened edges will crack within two drought cycles. Our slab designs account for this from the first engineering pass.
• Austin-code assumption. Homeowners and even some out-of-area designers model detached ADUs on Austin’s relaxed parking and size allowances, then hit Pflugerville’s stricter setback and height limits at review. Full redesign follows. We start with Pflugerville’s Unified Development Code on day one.
• Architectural review rejection. Even with city approval, HOA architectural committees in master-planned communities reject materials, colors, or rooflines that don’t match the subdivision’s design standards. We compile the submittal packet, file it, and schedule construction around the approval date so you’re not paying for half-finished framing while a committee meets.
