Why Lodgewick ADU Dallas Is Heath’s Preferred ADU Builders Company
Heath homeowners keep calling us after getting burned by contractors who promised a price, then changed it. That’s what led Russ Delmar to build Lodgewick ADU Dallas around a simple rule: every number goes in writing before the first nail is driven. The Kingswell Guarantee covers it all – a written price, a defined arrival window, a clean job site, and a written guarantee on the entire project. If something isn’t right within 365 days, we come back and fix it. Free. That’s the 365-Day Done Right Promise, and it’s on paper before we start.
Our ADU Builders team has framed detached units across Heath, from The Sanctuary to neighborhoods off Smirl Drive. We’re familiar with the setbacks, the soil, and the inspection rhythm here. Calls are answered by a live person, 24 hours a day – not a voicemail loop. When a Heath homeowner calls at 9 p.m. with a question about their build schedule or their written guarantee, a person picks up. Background-checked, uniformed technicians show up on the stated day, in the stated window. Our reputation in Heath is built on that consistency, not on ads.
ADU Construction in Heath
ADU Construction in Heath means building a separate living space on your existing residential lot – a studio, one-bedroom, or two-bedroom unit with its own kitchen, bath, and entrance. For Heath specifically, that almost always means a detached backyard build. Heath’s zoning doesn’t allow converting an attached garage into an ADU, so the conversation starts with placement and foundation depth, not with ripping drywall out of an existing structure.
What Builders Actually Do
We handle the lot survey, zoning confirmation against Heath’s 10,000-square-foot minimum, architectural drawings sized to the 800-square-foot conditioned floor area cap, foundation, framing, mechanicals, drywall, finishes, and the final inspection. Heath requires that the setback from the rear property line be maintained at 10 feet, and that detail gets locked into the drawings before we ever break ground. Our familiarity with Heath’s code means the first plan submittal passes more often than not.
What ADU Construction Costs in Heath
A detached ADU construction in Heath runs from $165,000 for a compact 500-square-foot studio to $310,000 or more for a 750-square-foot two-bedroom with premium finishes. Site work drives the range: flat lots with easy access cost less than sloped lots needing retaining walls or lots with existing trees that have to come out. We put every line item in writing before work starts. No change-order surprise at the door, ever.
Detached ADU in Heath
Detached ADU work in Heath is our most common project type. Heath’s zoning pushes nearly every homeowner toward this option: the lot must be zoned single-family residential with at least 10,000 square feet, and the ADU cannot exceed 800 square feet of conditioned floor area. A detached ADU sits in the backyard, fully separate from the primary house, which gives you a quiet rental unit or a private space for aging parents.
Placement and Foundation
Placement is the first decision, and it’s a Heath-specific one. The 10-foot rear setback, the 5-foot side setbacks, and the location of existing utilities all shape where the unit can sit. We survey the lot, confirm the plat meets Heath’s 10,000-square-foot minimum, and only then draw the foundation plan. In Heath’s clay-heavy soil, we typically recommend a slab-on-grade foundation with deeper edge beams to reduce movement across wet and dry seasons.
Interior Layout Under the 800-Square-Foot Cap
Here’s the detail most builders miss: exterior wall thickness counts against the conditioned floor area cap. If you frame to the full 800 square feet on the outside dimensions, the interior conditioned area will technically exceed Heath’s cap and the final inspection will fail. We design to roughly 760 to 780 square feet of interior living space, leaving room for wall depth. That’s the difference between passing inspection the first time and spending weeks resubmitting plans.
Trusted Brands We Service in Heath
We work with established ADU brands and materials so Heath homeowners can choose between prefab speed and custom flexibility. For a faster build on a straightforward lot, we price Boxabl and Plant Prefab units. For custom framing, James Hardie siding is our default exterior because it holds up to North Texas heat and hail better than vinyl. We match the brand to your lot, budget, and timeline – and we stock the fasteners, trim, and touch-up materials for these systems locally, so a warranty call doesn’t mean waiting two weeks on a shipment.
Common ADU Builders Problems We See in Heath Homes
- Submitting plans before verifying lot size. A lot that’s 9,800 square feet is a hard rejection in Heath. We confirm the plat against the 10,000-square-foot minimum before any drawing goes to the city, which saves you a full resubmission cycle – typically two to three weeks.
- Assuming a garage conversion will be approved. Heath does not permit converting attached garages into ADUs. Builders who don’t check this waste weeks redesigning as a detached unit. We check first, every time.
- Framing to the 800-square-foot maximum on the exterior. Exterior wall thickness eats into conditioned floor area. If the outside dimensions are 800 square feet, the inside is less, and the city’s measurement is what matters. We frame to interior dimensions that keep the conditioned area under the cap.
- Ignoring the 10-foot rear setback. On narrow lots, a misplaced foundation can push you into a variance hearing. We survey and stake the footprint before concrete is poured, and the inspector knows the setback was respected because it’s drawn, staked, and confirmed on site.

FAQs About ADU Builders in Heath
Heath’s zoning code permits ADUs only on lots zoned single-family residential with at least 10,000 square feet, with a maximum of 800 square feet of conditioned floor area, and it does not allow converting an attached garage into an ADU. That means if you want an ADU in Heath, you’re almost always building a detached backyard unit. Call (361) 204-4652 and we’ll confirm your lot’s zoning and size before you spend money on plans.
The 800-square-foot cap applies to conditioned floor area, which means interior living space measured inside the exterior walls. Two bedrooms in 760 to 780 square feet of conditioned space works, but it’s tight – expect roughly 400 square feet for the bedrooms and bath, 200 for the kitchen and living area, and the rest for circulation and storage. Wall thickness typically eats 15 to 20 square feet, so we design to interior dimensions under the cap, not to the exterior footprint. We’ll show you the exact floor plan before you commit to anything.
A Heath ADU needs the standard sequence: foundation inspection, framing inspection, rough-in for electrical and plumbing, insulation, and a final inspection that confirms the conditioned floor area is under the 800-square-foot cap and the rear setback is at least 10 feet. If the unit will have a separate electric meter, the city also requires a separate inspection on the service panel. We schedule every inspection and walk with the inspector, so nothing gets missed. If an inspection fails, we fix it and get it re-inspected at no additional cost under the 365-Day Done Right Promise.
Heath’s zoning review typically takes 3 to 6 weeks on a first submittal, and if a plan gets rejected for a lot-size or setback issue, add another 2 to 3 weeks for the resubmission. Then there’s the inspection backlog: Heath schedules inspections in sequence, and each one is a week or two apart during peak building season. A realistic calendar for a Heath detached ADU is 6 to 10 months, not 4 to 6. Builders who quote shorter timelines are usually quoting the national average, not the Heath process. We give you a written schedule with the Heath timeline built in.
Under The Kingswell Guarantee, the written price we give you before work starts is the price you pay. The only things that would change it are a change you request – like upgrading from standard siding to James Hardie plank, adding a separate meter, or moving the unit’s footprint after the foundation plan is set – or a condition we couldn’t see before digging, like a buried utility line or unexpected rock. Even then, we write the change order with the new price before that work starts. No price changes at the door, ever. Call (361) 204-4652 to get your written estimate.
