Cover ADU in Austin, CA | Ellery ADU Studio
We’re an independent Cover service provider working across Austin, and the quick answer is this: we repair, upgrade, and retrofit Cover panelized ADUs, and the thing that separates our work here from anywhere else is that we build for Austin’s east-west geology divide. A Cover unit on Blackland Prairie clay east of I-35 needs a different foundation strategy than one on Hill Country limestone west of it. Most Cover problems we see in Austin trace back to that one fact. Call (971) 497-2402 for a written estimate before any work starts.
Why Austin Residents Choose Us for Cover Service
Nadia Ellery founded Ellery ADU Studio in 2015, the year California’s ADU permitting landscape shifted, and she built the practice around a simple idea: the permit set is the product, not an afterthought. That same discipline carries into every Cover unit we touch in Austin. We know these panelized systems from the factory floor to the final inspection, and we’ve spent years working through the specific ways they interact with Austin’s housing stock, its floodplain map, and its summer heat loads.
We’re not authorized by Cover, and we won’t pretend otherwise. What we are is an independent design-build studio that specifies and coordinates Cover systems within a single contract, which means we’re accountable for the whole thing: the drawings, the permit set, the utility tie-ins, and the construction. If a panel joint fails because the foundation wasn’t engineered for Austin’s expansive clay, that’s our problem to fix, not someone else’s to point at. Every project gets a written price before work begins, a documented photo record on every visit, and a 365-Day Done Right Promise in writing. Under Haven Standard Clause 1, the scope is locked at signing.
Common Cover ADU Problems We Solve in Austin
- Panel joint separation from Blackland Prairie clay heave. East of I-35, Austin sits on expansive clay that swells and shrinks with seasonal moisture. Cover units on shallow pier-and-beam foundations in 78702, 78721, and 78723 routinely develop visible panel seam gaps within 18 to 24 months. We drill deeper piers, re-level, and re-seal joints with Cover-specific connectors where structural integrity matters.
- Undersized mini-split HVAC that can’t hold temperature in July. Cover studios spec’d for milder climates struggle during Austin’s sustained 100°F weeks. We replace undersized units with right-sized systems and rebalance duct runs so the space stays rentable through August.
- Electrical faults from original 100-amp panels. The 1940s through 1970s bungalows that dominate East Austin were wired for a different era. Energizing a Cover ADU on a 100-amp panel trips breakers, damages appliances, and fails city inspection. We handle the service upgrade to 200 amps as part of the same contract.
- Moisture and vapor barrier failures in Waller Creek floodplain zones. Detached Cover units inside mapped floodplain areas in 78702 or 78721 can show wall and ceiling moisture within a year if the slab elevation or vapor barrier was under-specified. We assess the floodplain map, pull FEMA elevation certificates when required, and correct the envelope.
- HOA deed restriction conflicts. Austin’s HOME ordinance allows up to three units by right, but outer-ring subdivisions along South Manchaca, Rundberg, and annexed Travis County tracts often carry HOA covenants that clash with city zoning. We handle the documentation and compliance path before you spend a dollar on panels.
Cover Service in Austin: What Local Conditions Mean for Your Equipment
The 2023 HOME ordinance, Home Options for Middle-income Empowerment, made Austin the most ADU-deregulated major city in Texas. Up to three residential units by right on any single-family lot citywide. No variance process. That’s the headline. But here’s the part generic pages miss: in the 78702 ZIP code, Waller Creek and its mapped tributaries cut through dozens of older residential lots, which means a Cover ADU that would sail through permitting in 78704 or 78745 can trigger city floodplain review, FEMA elevation certificates, fill permits, and months of delay. We’ve seen homeowners in the Chestnut neighborhood discover this only after their Cover panels were already ordered. It’s not a reason to avoid East Austin. It’s a reason to know your lot’s floodplain status before you commit to a foundation design. The drawing either satisfies the inspector or it doesn’t. Let’s make sure it does.
Cover Models & Products We Service in Austin
We service the full Cover lineup: the S-Series Studio, the One-Bedroom Unit, the Backyard Cottage, and new detached ADU configurations in Austin. For structural components, panel connectors, and envelope materials, we use Cover-specific OEM parts when they’re available and when the failure mode demands factory tolerances. For HVAC, electrical, and plumbing components, we substitute high-quality aftermarket parts that meet or exceed Austin code, which usually means faster turnaround and better long-term performance in this climate. Severe panel damage or outdated electrical typically points to a full panel replacement or re-siding, not piecemeal patchwork. We’ll tell you which one your unit needs and put it in writing.
Cover Service Pricing in Austin
Foundation work on our Garage Conversion ADU in Austin typically runs $8,000 to $22,000 depending on whether you’re on Blackland Prairie clay needing drilled piers or Hill Country limestone requiring saw-cutting for utilities.

FAQs - Cover ADU in Austin
If your lot sits within a mapped Waller Creek tributary zone in 78702 or 78721, yes, the City of Austin will likely require floodplain review, a FEMA elevation certificate, and possibly fill permits before your Cover ADU can be permitted. This applies even when you see no water near your property. We check the floodplain map before you order panels. Call (971) 497-2402 for a lot-specific assessment.
Almost never. A 100-amp panel on a 1940s East Austin bungalow will trip when a Cover unit’s heat pump cycles on, and the city won’t pass the electrical inspection. You’ll need a 200-amp service upgrade. We scope it as part of the same contract so the work happens once, not twice.
On Austin’s east side, the usual cause is panel joint separation from Blackland Prairie clay heave under shallow piers. The clay swells with moisture, lifts the foundation unevenly, and the panel seams open. We drill deeper helical piers, re-level the unit, and re-seal the joints. Call (971) 497-2402 for a foundation inspection and a written repair price.
Yes. The 2023 HOME ordinance allows up to three residential units by right on any single-family lot citywide, which eliminated the variance process that slowed ADU work for decades. The remaining hurdles are site-level: floodplain review, HOA deed restrictions, and utility capacity. We handle all three within the permit set.
West of I-35, shallow Hill Country limestone often sits close to grade, which can require saw-cutting or blasting for utility trenches. A slab-on-grade with proper vapor barrier typically works well, but the site-specific limestone depth determines the right approach. Call (971) 497-2402 for a free site walk and a foundation recommendation in writing.
