Building an accessory dwelling unit, which is simply a second smaller home on your existing lot, in North Dallas means navigating Dallas Development Code Section 51A-4.209, managing expansive clay soil, and getting real numbers in writing before excavation starts. We’ve built detached ADUs, garage conversions, and studio additions across Preston Hollow, Far North Dallas, and the neighborhoods around LBJ Freeway and the Dallas North Tollway, so we know what the City of Dallas Building Inspection Division will flag and what it won’t. If you’re pricing a project, call (361) 204-4652 and we’ll walk the lot with you before you spend another hour guessing.
Why Lodgewick ADU Dallas Is North Dallas’s Preferred ADU Builders Company
Russ Delmar leads our North Dallas team, and he’s spent enough time in front of the Dallas permit counter to know which drawings pass the first time and which ones get bounced back. Our customers in North Dallas keep telling us the same thing: they’d been burned before by contractors who gave a low verbal number, then changed the price once the slab was poured. That doesn’t happen with us. The Kingswell Guarantee means a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee on the whole build. If something isn’t done right within 365 days, we come back and fix it. Free.
We answer calls from North Dallas homeowners at all hours. A live person picks up. Not a voicemail loop. When you call with a question about your Abodu prefab order or your foundation piers, you get a person who knows your project, not a chatbot.
ADU Contractor in North Dallas
An ADU Contractor in North Dallas handles the entire build from the first site survey through the final City of Dallas inspection. When a homeowner in places like Bent Tree or Prestonwood decides they need a detached unit for an aging parent or rental income, the contractor is the one who pulls the permit package, schedules the concrete and framing subs, manages the structural engineer if the soil shifts, and keeps the project on a calendar that actually reflects how long things take here. Our team at ADU Builders does exactly that, with every commitment in writing.
Full Project Management
We coordinate the architectural drawings, the Dallas-specific permit package, the foundation work, and the final inspections. You don’t chase down a concrete sub or wonder whether the electrician filed the rough-in inspection. We do.
Permit and Inspection Handling
North Dallas ADU permits run through the City of Dallas, not a neighboring municipality. That means setbacks, height caps, and the required 5-foot separation from your primary structure all live under one code section. We know what it says because we’ve filed under it dozens of times.
ADU Design in North Dallas
ADU Design in North Dallas has to account for lot shapes that range from wide Preston Hollow acreage to tighter Far North Dallas subdivisions, plus the height cap and setback rules in Dallas Development Code Section 51A-4.209. A good design also plans for the soil. If your lot has expansive clay, and much of North Dallas does, the foundation needs deeper piers than a standard slab, and that affects the earliest drawings, not just the pour. We design with those costs visible from day one, working with the homeowner to match a prefab unit from Mighty Buildings or a custom stick-built studio to the actual lot constraints.
Lot Assessment and Feasibility
Before any plans are drawn, we walk the lot, check the slope, the access for equipment, and the setback distances from your house and property lines. That tells us, and you, whether a detached ADU works where you want it or whether a garage conversion makes more sense.
Custom and Prefab Layouts
We work with both custom designs and established prefab brands, including Boxabl and Plant Prefab. For a North Dallas homeowner who wants a faster path to occupancy, a prefab unit can cut weeks off the framing phase, but the foundation and permits still follow Texas and Dallas rules. We plan around that reality.
Trusted Brands We Service in North Dallas
We install and finish ADUs from several manufacturers North Dallas homeowners keep asking about. Mighty Buildings and Boxabl come up often for their factory-built panels and fast assembly. Plant Prefab is another we’ve placed on North Dallas lots. Since we’re local to the Dallas-Fort Worth metro, coordinating material delivery to your property doesn’t involve a 3-state logistics chain. If a panel arrives damaged, we get the replacement ordered the same week, not next month.
Common ADU Builders Problems We See in North Dallas Homes
- Expansive clay soil surprises. North Dallas sits on clay that swells when wet and shrinks in drought. A standard slab can crack within a few seasons, so many ADUs here need piers, and that’s a $10,000 to $25,000 line item that the low-bid guy never mentioned.
- Stop-work orders from missing Dallas permits. The City of Dallas Building Inspection Division enforces ADU rules that differ from Richardson’s and Plano’s. A contractor who files the wrong package or skips a required separation setback gets the site shut down, and the homeowner pays the delay.
- HOA friction in neighborhoods like Preston Hollow. Some North Dallas HOAs have their own review process for any new structure, even one that the City approves. We’ve seen projects stall for weeks because nobody checked the HOA covenants first.
- Concrete and framing subs booked 6 to 8 weeks out. North Dallas is busy, and the established crews are scheduled far in advance. The contractor who promises a 4-month ADU without accounting for that queue is setting you up for a fall.
Pricing for ADU Builders in North Dallas, TX
A detached ADU in North Dallas typically runs from $195,000 to $360,000 for a custom build in the 400 to 800 square foot range. A studio ADU on a simpler lot can land closer to $140,000 to $180,000 if the soil doesn’t require deep piers. A garage conversion usually sits between $95,000 and $160,000 depending on whether you’re upgrading the existing slab and bringing in new electrical service. Prefab units from Boxabl or Plant Prefab often fall between $160,000 and $280,000 all-in with foundation, delivery, and finishing. The North Dallas variables that move the number are soil conditions, HOA requirements, and how far your meter and sewer line sit from the new footprint. Call (361) 204-4652 and we’ll give you a written line-item price before you commit to anything.

FAQs About ADU Builders in North Dallas
Dallas Development Code Section 51A-4.209 requires a detached ADU to sit at least 5 feet from the primary structure, stay at or under one story with a 25-foot height cap, and respect the standard lot setbacks based on your specific zoning. Those numbers are fixed city-wide, but how they apply to your lot, especially a corner lot or one with an existing easement, is what we check before drawing anything. Call (361) 204-4652 for a free lot assessment.
Allow 6 to 12 weeks for the City of Dallas to review and approve a complete ADU permit package. That assumes the drawings are accurate and the site plan meets the 51A-4.209 requirements. If the package is missing a required detail, the review clock resets and you lose another 3 to 4 weeks. We file complete packages so the timeline doesn’t get padded with back-and-forth corrections.
Yes, prefab units from Abodu, Boxabl, and similar manufacturers can be placed on North Dallas lots, provided they meet Dallas’s height limit, setbacks, and foundation requirements. The prefab frame goes up in days once the concrete is ready, but you still need the same City of Dallas permit and soil preparation as a stick-built ADU. We’ve installed both paths and can help you compare the real total cost.
Expansive clay soil that requires deeper piers is the biggest one, often adding $10,000 to $25,000 to the foundation scope. A buried abandoned septic tank, an undersized electrical service that needs a panel upgrade, or a sewer line that has to be re-routed around the new footprint will also move the number. These are discovered during the site survey and soil test we run before the written price is set, so they should not be surprises after excavation begins.
In many Preston Hollow and Far North Dallas subdivisions, yes. The HOA likely has design-review covenants that apply to any new structure, even one the City of Dallas approves. That review can add 30 to 60 days before construction starts. We pull the HOA requirements early and fold them into the project calendar so the HOA doesn’t become the reason the job stalls mid-build. Call (361) 204-4652 to get your lot assessed.
