A detached ADU in Stafford typically costs between $185,000 and $310,000, while a garage conversion runs $95,000 to $165,000. Most projects take 5 to 9 months from first plan to final inspection, largely because Stafford’s city-owned utility adds coordination steps most Houston suburbs don’t have. Call (361) 326-2313 and we’ll give you a written price before any work starts.
We know Stafford differently than a builder who just drops in from across the highway. The homes off Murphy Road, the lots along Cash Road, the newer subdivisions near Stafford Run and older streets near the Stafford Centre – they each present different setbacks, different soil, and different utility realities. Our crew has built ADUs in every corner of this city, and we’ve learned that in Stafford, getting the utility coordination right on day one is what keeps a project on schedule.
Russ Delmar leads our Houston team, and he’s built a crew that treats your property like a neighbor would. We show up in the window we give you. We leave the job site cleaner than we found it. And every promise we make goes in writing – including the price.
Why Lodgewick ADU Houston Is Stafford’s Preferred ADU Builders Company
Stafford homeowners call us because we do something most builders won’t: we put the total price in writing before we ask for a signature. No “we’ll see how it goes” pricing.

Every call to (361) 326-2313 is answered by a live person – 24 hours a day, 7 days a week. Not a voicemail. Not a chatbot. When you have a question about your build or your guarantee at 9pm, somebody picks up.
ADU Plans in Stafford
ADU Plans in Stafford are the first deliverable on any project, and they’re where our local knowledge saves you time and money. A full plan set for a detached ADU in Stafford runs $6,500 to $12,000, and a garage conversion plan set runs $4,000 to $8,500. These aren’t generic Texas plans. They account for Stafford’s specific setbacks, the city’s requirement that detached ADUs file separate trade permits for plumbing, electrical, and mechanical, and the utility coordination that Stafford Municipal Utility demands before permit approval.
Plan Set Scope
Your plan set includes architectural drawings, structural calculations for Stafford’s expansive clay soils, and the electrical and plumbing schematics the city requires. We also include a soil report allowance in every Stafford bid. Builders who skip this line item end up with change orders after digging starts. We don’t.
Utility Coordination Drawings
Because Stafford owns its own electric, water, and sewer, our plans include a utility coordination sheet showing the existing service drop, the proposed connection points, and any panel upgrade routing. The city reviews this before issuing the building permit, and getting it right the first time is what separates a 5-month project from a 9-month one.
ADU Contractor in Stafford
An ADU Contractor in Stafford is the licensed builder who carries the project from foundation to final inspection. Our build fees for a detached unit average $45,000 to $70,000 in contractor overhead and labor, on top of materials and the plan set. For a garage conversion, the contractor scope runs $25,000 to $45,000. What you get for that number: a dedicated project lead, background-checked and uniformed crews, daily job-site cleanup, and a written guarantee on every phase.
Foundation and Utility Work
Stafford’s clay soil moves. It expands when wet, contracts when dry, and it settles grading pads more than the sandier soils north of the city. Our bids include a soil report allowance and often a structural engineer’s foundation spec. Less experienced builders skip this, hit rock or shifting clay after excavation starts, and hand you a change order. We’ve seen it happen on lots off Dulles Avenue and around the older neighborhoods near Stafford Primary. It doesn’t happen on our jobs.
Trade Coordination
Stafford requires separate trade permits for plumbing, electrical, and mechanical on detached ADUs. We coordinate those filings through the city’s online portal and line up licensed trade crews who’ve passed Stafford inspections before. One missed trade permit delays the entire project. We file them all up front.
Trusted Brands We Service in Stafford
We work with the prefab and materials brands that perform well on Stafford lots. Boxabl units, with their factory-built precision, are a good fit for tighter Stafford backyards where framing on site would eat up your whole setback. Plant Prefab’s panelized systems handle Stafford’s settling soil better than fully rigid designs. And for siding that holds up to Gulf Coast humidity and summer heat, we spec James Hardie fiber cement on most of our Stafford builds. We keep stock and ordering channels prioritized for our Stafford customers, so material delays don’t stall your foundation work.
Common ADU Builders Problems We See in Stafford Homes
- Utility service upgrades that nobody planned for. Stafford Municipal Utility handles its own electrical service drops, and panel upgrades here can add 4 to 6 weeks before permit approval. A builder who doesn’t know this will promise you an 8-week permit and deliver 14.
- Foundation change orders from expansive clay. Stafford sits on clay that expands and contracts with the seasons. Our bids include a soil report allowance. Builders who skip it hit you with thousands in change orders after excavation starts.
- HOA and setback surprises on small lots. Some Stafford neighborhoods, including parts of Stafford Run, have restrictive rear and side setbacks that limit where a detached ADU can sit. We check those before you spend a dime on plans.
- Permit filings that miss separate trade permits. Detached ADUs in Stafford need plumbing, electrical, and mechanical permits filed separately through the city’s online portal. Missing one delays your final inspection by weeks.
Pricing for ADU Builders in Stafford, TX
A garage conversion in Stafford runs $95,000 to $165,000 all-in, depending on whether you’re adding plumbing for a bathroom and how much electrical your existing panel can handle. A detached ADU runs $185,000 to $310,000, with the spread driven by square footage, foundation type, and whether it’s a custom stick-built or a prefab installation like Boxabl or Plant Prefab. A junior ADU carved from existing interior space runs $65,000 to $110,000. Studio ADUs at the smaller end start around $150,000, and prefab installations often land 10-15% below custom framing on labor. We give a written price before work starts – always, on every project, no exceptions. Call (361) 326-2313 for a free estimate and a line-item number you can take to the bank.

FAQs About ADU Builders in Stafford
Yes. Stafford Municipal Utility controls electric, water, and sewer directly, so service upgrades, water taps, and sewer lateral work all have to go through city crews rather than a private utility or MUD district. Electrical panel upgrades can add 4 to 6 weeks before permit approval. Plan for that lead time early, and the rest of the schedule holds. Call (361) 326-2313 and we’ll walk you through a realistic Stafford timeline for your specific lot.
Stafford’s expansive clay soils expand when wet and contract when dry, which means foundations need a soil report and often a structural engineer’s spec. A standard slab that works on sandy Houston soils may need piers or a thicker mat foundation in Stafford, adding $8,000 to $20,000 depending on the lot. Our bids include that allowance up front, so the price you sign is the price you pay.
The neighborhoods around Stafford Run and some of the older subdivisions off Cash Road have rear and side setback rules that can shrink a detached ADU’s footprint by 100 square feet or more. We check Stafford’s zoning map and any HOA overlays before we quote your build, so you’re not paying for plans for a unit that doesn’t fit. Call (361) 326-2313 and we’ll verify your lot’s setbacks during the free estimate.
Yes. When an ADU is fed from the main house’s panel, Stafford requires its own electrical permit and a separate inspection for the subpanel and feeder run. If the main panel can’t handle the additional load, you’re looking at a service upgrade through Stafford Municipal Utility, which adds 4 to 6 weeks before permit approval. We scope this into every Stafford plan set.
Yes. A detached ADU in Stafford is assessed as new construction and will increase your property’s appraised value. The exact amount depends on the unit’s square footage and finish level, and we’d suggest talking to the Fort Bend Central Appraisal District for a specific number. What we can tell you is the construction cost before you commit – call (361) 326-2313 for a written, no-obligation estimate.
A Real Stafford Project, Start to Finish
Our crew built an attached ADU in the Stafford Run neighborhood, where the existing panel was maxed out and the garage slab had settled 2 inches. We had to coordinate with Stafford Municipal Utility to upgrade the service drop, pour a new mat foundation for the James Hardie-clad 600-square-foot unit, and re-route the sewer lateral to avoid a 40-year-old pecan tree – all before inspections could close out. That project is what we mean when we say Stafford is different. Not harder, just different. And we know the difference.
If you’re considering an ADU in Stafford, start with a written price. Call (361) 326-2313 and we’ll schedule a free estimate, walk your lot with you, and hand you a line-item number that accounts for Stafford’s utilities, soils, and permit realities. No surprises. No pressure. Just a straight answer from a builder who knows this city.
