ADU in Hurst, TX
An ADU in Hurst is a fully permitted secondary dwelling on your existing lot, and for most homeowners here that means converting an attached garage because the standard 1960s and 1970s ranch lots rarely leave room for a detached build. Hurst’s Unified Development Code, paired with rear setback limits that squeeze detached footprints, makes design and permitting strategy the deciding factor in whether a project pencils out. Nadia Ellery and our team at Ellery ADU Studio handle that paperwork as the core deliverable, not an afterthought. Call (971) 497-2402 to start with a written price.
Why Hurst Homes Are Different
Hurst is a nearly built-out Mid-Cities suburb. The dominant housing stock is single-story brick-veneer ranch homes from the late 1950s through early 1980s on modest lots, and that shapes everything about ADU work here. Most of those homes came with 100-amp electrical panels and a single-zone HVAC system, both of which routinely fail today’s inspection requirements the moment a garage becomes living space. You are not just adding square footage; you are upgrading the systems behind it.
The soil is the second silent constraint. Tarrant County sits on expansive Blackland Prairie clay that swells when wet and contracts hard when dry. A new detached ADU slab has to be engineered for that movement or you’ll chase cracks for years. And since the February 2021 freeze, Hurst inspectors look harder at utility line depth and insulation on detached builds. These are not generic Texas conditions. They are specific line items on a Hurst permit set, and they’re why a written scope from the start matters more than a rough verbal estimate.
Our Main Hurst Services
Two ADU paths dominate inquiries from Hurst homeowners. Both carry the same written-price guarantee, and both start with the same question: what does the lot and the existing structure actually allow?
Garage Conversion ADU in Hurst
Most Hurst ranch homes have an attached single or double garage sitting on a slab that was never poured for habitable use. Converting it is often the fastest permitted path to an ADU because the footprint already exists and the roof is already tied in. The catch is the slab itself: many Hurst garage slabs measure 3.5 inches with no vapor barrier, which triggers a full replacement before the city will approve the conversion. We inspect that early and put the number in writing. See the full scope at Garage Conversion ADU in Hurst.
New Detached ADU in Hurst
A detached ADU on a Hurst lot usually means designing within tight rear setback limits. The Unified Development Code controls how close the new structure can sit to the property line, which often leaves a narrow buildable rectangle behind the home. Blackland clay soil adds an engineered foundation requirement. Prefab and modular systems from manufacturers like Abodu and Cover can shorten on-site time significantly, and we specify those within the same single contract. Read the full breakdown at New Detached ADU in Hurst.

ADU Design & Permitting in Hurst
ADU Design and Permitting in Hurst is the service that decides whether your project gets approved the first time, and most Hurst submissions stall because the drawings do not account for two local realities: the Unified Development Code’s setback language and the 100-amp panel sitting in a 1960s-era utility room. The permit set is the product. Everything else follows from it. Our studio, founded by Nadia Ellery in 2015, prepares drawings, structural calculations, and energy compliance documentation as one package under ADU Design & Permitting, so there is no designer-versus-builder gap when the inspector asks a question.
Site Assessment
Signs you need it
You have a written estimate from another contractor but no measured survey confirming whether the existing garage slab or rear yard can actually support the ADU shown on the drawing.
What it costs in Hurst
A Hurst site assessment typically runs $800 to $1,500 depending on whether we include a topographic survey and utility locate, with the full scope priced in writing before we step on the property.
How we do it
We measure the lot against the Unified Development Code’s setback requirements, check the existing slab thickness and panel capacity, and document every finding with photos, before issuing a written go/no-go recommendation with specific numbers attached.
Permit Application
Signs you need it
Your garage conversion or detached ADU plans are drawn, but you’ve already received one correction letter from the City of Hurst and are uncertain what the reviewer actually needs changed.
What it costs in Hurst
A full permit application package for a Hurst ADU typically runs $4,000 to $9,000 including drawings, structural engineering, energy compliance forms, and submission management, with city fees billed separately and shown in writing upfront.
How we do it
We prepare the complete submittal set in the city’s required format, file it, track the review, answer the plan checker’s questions with written responses, and resubmit until the permit is issued.
What ADU Design & Permitting Costs in Hurst
| Item | Typical range in Hurst |
|---|---|
| Site assessment with survey | $800 - $1,500 |
| Design & blueprint set | $3,000 - $7,000 |
| Permit application & management | $4,000 - $9,000 |
How long does ADU permitting take in Hurst?
Plan for 60 to 120 days from submittal to issued permit in Hurst, depending on review workload and whether a variance is needed. We track every review cycle and respond within days, not weeks. Call (971) 497-2402 for an exact timeline on your lot.
Do I need a variance for an ADU in Hurst?
Many Hurst garage conversions do not need a variance because they use the existing footprint, but detached ADUs often trigger setback variances on standard ranch lots. We check the exact rear and side setback language on your lot before you spend money on drawings.
Junior ADU & Interior Conversion in Hurst
A Junior ADU or interior conversion in Hurst typically means carving a studio or one-bedroom dwelling out of space already inside the home’s envelope: a large family room, a finished basement, or an oversized primary suite. For Hurst ranch homes with no buildable rear yard and a garage too small to convert, this is often the only ADU path that clears zoning. Our Junior ADU and Interior Conversion work is quoted, drawn, permitted, and built under one contract through Junior ADU & Interior Conversion, with a written price before any work starts.
Room-to-ADU Conversion
Signs you need it
You have a large interior room or finished area with its own exterior access opportunity, and you want rental income or a family suite without altering the home’s footprint.
What it costs in Hurst
A room-to-ADU conversion in Hurst typically runs $60,000 to $120,000 depending on whether a kitchenette, separate entry, and upgraded electrical are included, all priced in writing before we begin.
How we do it
We seal off the space with proper fire separation, add the required kitchen or kitchenette, install a separate entrance where possible, and upgrade the panel and HVAC feed so the unit passes Hurst inspection without surprises.
Attached Addition ADU
Signs you need it
Your garage is too narrow or slab-inadequate for conversion, but your side yard has enough width to add a narrow attached wing within an existing setback allowance.
What it costs in Hurst
An attached addition ADU in Hurst generally runs $90,000 to $180,000 for a studio or one-bedroom build-out including foundation, framing, mechanical, and finishes, depending on soil corrections and utility distances.
How we do it
We engineer the addition as a load-bearing extension of the existing home, tie the roofline and foundation per the permit set, and run a separate sub-panel and HVAC zone so the ADU operates independently.
What Junior ADU & Interior Conversion Costs in Hurst
| Item | Typical range in Hurst |
|---|---|
| Room-to-ADU conversion | $60,000 - $120,000 |
| Attached addition ADU | $90,000 - $180,000 |
| Interior JADU with separate entry | $50,000 - $95,000 |
Can I convert a bedroom into a JADU in Hurst?
Yes, if the room meets minimum size, egress, and kitchen requirements under Hurst’s code, and the primary home retains its required bathroom count. We document the separation and fire-rating so the permit review goes smoothly. Call (971) 497-2402 for a written scope.
Does an interior ADU need its own electrical panel?
Not always, but Hurst inspectors typically require a separate sub-panel for an ADU with a kitchenette and its own heating. The original 100-amp main panel on older Hurst homes often forces a service upgrade first, which we include in the written price.
ADU Site Prep & Utilities in Hurst
Site prep and utility work in Hurst is where the Blackland Prairie clay and the 2021 freeze lessons collide. Any detached ADU needs an engineered slab or post-tension foundation that will not heave when the soil cycles wet to dry, and any new water or sewer lateral has to be buried to code depth with insulation where required. Our ADU Site Prep & Utilities work covers the ground-up scope: grading, foundation, panel upgrades, plumbing laterals, and gas line extensions, all under the same written price that covers the rest of the project.
Foundation & Grading
Signs you need it
Your rear yard slopes noticeably, or a test dig shows the existing garage slab is 3.5 inches with no vapor barrier, which will not pass Hurst inspection for habitable space.
What it costs in Hurst
Foundation work on Hurst’s expansive clay typically runs $12,000 to $35,000 for an engineered slab on a detached ADU, including soil correction, vapor barrier, and compaction documentation.
How we do it
We run a geotech test to measure clay expansion, design the slab or post-tension system for that specific soil, grade the pad for drainage away from the structure, and document every lift and test for the permit file.
Electrical Panel Upgrade
Signs you need it
Your Hurst home still has the original 100-amp panel, and the ADU will add a kitchenette, water heater, and HVAC load that pushes you past the panel’s rated capacity.
What it costs in Hurst
A 200-amp panel upgrade in Hurst typically runs $4,500 to $9,000 including replacement meter base, grounding, and city inspection, with the exact scope and price fixed before we start.
How we do it
We replace the existing panel, bring the grounding and bonding up to current code, run a new sub-panel to the ADU, and schedule the city inspection as part of the permit package we already filed.
What ADU Site Prep & Utilities Costs in Hurst
| Item | Typical range in Hurst |
|---|---|
| Engineered foundation & grading | $12,000 - $35,000 |
| Electrical panel upgrade (200A) | $4,500 - $9,000 |
| Plumbing lateral & gas line extension | $6,000 - $18,000 |
Does Hurst require a geotech report for a detached ADU?
Yes, for any new detached foundation on Hurst’s expansive clay, the city expects a geotechnical report supporting the slab design. We commission it and build the cost into the written foundation scope. Call (971) 497-2402 to discuss your specific lot.
Why do utility lines cost more in Hurst than in newer suburbs?
Older Hurst neighborhoods often have shallow original services and mature trees, so trenching for new laterals runs longer and deeper, and the February 2021 freeze pushed insulation requirements up. Our written quote includes the depth and insulation spec, so the number is real, not estimated.

Two things push ADU prices up in Hurst more than anywhere else in the Mid-Cities: an original garage slab that fails the habitable-space inspection and a 100-amp panel that cannot carry the new load. Both items appear in our written price before work starts, per Haven Standard Clause 1, so the number you sign is the number you pay.

What Hurst Customers Say
"Garage conversion finished on the drawings and close to the schedule. They were honest that the sewer connection was the unknown, and it was."
- Arjun D."The permit set and the build were one contract with one number. Our neighbours used two firms and spent a year watching them blame each other."
- Helena V."The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
- Odette N.
