Cover Home Additions & ADU: The Fort Worth Owner’s Guide
If you own a Cover home and are planning an addition or an ADU in Fort Worth, you’re looking at an installed price between $45,000 and $130,000 for a home addition, and $90,000 to $220,000 for a freestanding ADU, depending on square footage, foundation work, and finish level. We’re Elmstead Remodeling Fort Worth, a Cedarwell company, and we’ve been walking Fort Worth families through this exact decision for years. Most owners contact us after a bid from a general contractor comes back vague, or after they realize their Cover floor plan requires structural changes nobody explained on the first call.
We’re an independent service provider, not affiliated with Cover. What that means for you: we work on Cover homes regularly, we know how these structures are framed and finished, and we write a fixed price before any work begins. Graham Stein, our owner, insists on that. If you’re researching what an addition or ADU actually costs in Fort Worth, not a national average, you’re in the right place.
Which Cover Models This Applies To
Cover builds homes in a range of configurations, from compact one-story designs to larger two-story models. The addition or ADU work we do applies broadly, but there’s a compatibility detail you should know before any contractor starts quoting: Cover homes in Fort Worth are typically set on pier-and-beam or slab foundations, and the foundation type drives the entire addition cost. A slab addition means cutting into existing concrete, matching elevation, and dealing with plumbing runs that may not align with the original layout. Pier-and-beam gives more flexibility for running new utilities underneath, which often saves money on plumbing and electrical rough-in.
The second thing we check: wall cavity depth and roof pitch. Cover homes use modular wall panels, and matching the exterior cladding and roofline to the existing structure matters more than most homeowners expect. On the interior, we specify materials from partners like KraftMaid, Cambria, and Silestone when the project calls for cabinets or countertops, because those brands have warranties you can verify independently, and because they hold up better across Fort Worth’s hot summers and clay-heavy soil movement.
For parts compatibility specifically: if you’re adding onto a Cover home built before 2019, we’ve found the original window and door sizing sometimes doesn’t match current Cover spec sheets. We measure every opening ourselves before ordering anything. That’s part of the written price promise, and it’s why our quotes don’t change after the crew shows up.

Signs Your Cover Home Additions & ADU Planning Is Going Off Track
Most Fort Worth homeowners don’t have a failed part when it comes to additions. They have a failed process. Here’s what that looks like:
- You’ve received three bids and they differ by $40,000 or more. That gap usually means one contractor is pricing foundation work correctly and another is hoping you won’t notice. In Fort Worth’s expansive clay soil, foundation prep is not optional and not a place to save money.
- No one has asked about your Cover home’s existing roofline. Tying a new roofline into an existing Cover modular roof is where additions leak or sag later, especially after a North Texas hail season. If a contractor hasn’t looked at the roofline, they haven’t done the job.
- The quote is a single page with a bottom line and nothing else. You don’t know what materials you’re paying for, what the crew will protect during the work, or what happens if a wall needs to be opened and the scope shifts. Elmstead Remodeling Fort Worth gives you a written price with line items, before any work starts, every time.
- Nobody mentioned the permit timeline. ADUs in Fort Worth require city permits, and depending on the neighborhood and whether it’s a detached unit or a garage conversion, plan review can take weeks. A contractor who shrugs at the timeline is one who hasn’t pulled permits in Fort Worth recently.
- Quiet hours and kids’ schedules were never discussed. If you’re living in the house during the work and a contractor hasn’t asked about nap time, school pickups, or where the dog goes during noisy demo, that’s a red flag. Graham schedules noisy demolition outside school-pickup hours whenever families are living in the home. It’s not a special favor; it’s how the crew works.

AfterReplacement Cost & What’s Included
For Fort Worth specifically, here’s what we tell families to expect:
| Project Type | Typical Installed Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
The range is wide for real reasons. A 300-square-foot bump-out on a slab foundation with a bathroom will land differently than a 900-square-foot second-story addition. An ADU with its own kitchen, full bath, and separate meter will cost more than a detached guest room with a half bath and a window unit. What we promise: the written price you get from us includes the materials, labor, permits, and the protection. Shoe covers and drop cloths on every visit, a photo of the clean-up before the crew leaves, and pet-safe product choices where there is a choice. These aren’t add-ons; they’re in every Elmstead job.
And if anything isn’t done right after the job is complete, the 365-Day Done Right Promise means we come back and make it right. That’s stamped on every project we complete in Fort Worth.
DIY or Call Us?
Some parts of an addition or ADU project are fine to handle yourself. Some are genuinely dangerous and should not be touched without a trained professional.
Here’s the honest split. You can safely measure your lot, review your Cover home’s original floor plan, sketch the room you want, and research the finishes you like. You can also look up your neighborhood’s setback requirements through Fort Worth’s planning department. Those steps save time and money, and we encourage them.
What you should not DIY: anything that involves moving load-bearing walls, cutting into the existing roof structure, running new electrical service, or pouring a foundation. In a Cover home, the modular wall panels and factory-set connections are not forgiving of amateur modifications. A wall that carries roof load cut without proper temporary support can fail suddenly and catastrophically. If you’re considering a garage conversion, the existing electrical panel may need a service upgrade, and that’s work for a licensed electrician on our crew, not a weekend project. For anything structural, call (682) 708-9180 and let us look at it before any saw comes out. Estimates are free, and you’ll get a written number, not a vague guess.
FAQs
Done correctly, you should expect 50 years or more from the structural work, with finishes lasting 15 to 25 years before they feel dated or show wear. Fort Worth’s climate is hard on exterior materials, the hot sun fades siding and roofing fast, and the clay soil moves enough to test any foundation detail. Proper foundation prep and flashing around where the addition meets the original home matter more than anything else for longevity here. Call (682) 708-9180 and we’ll tell you exactly what your specific lot requires.
Sometimes yes. If the goal is a bigger kitchen or a new bedroom and your existing footprint allows it, reworking interior walls and reconfiguring space can be far less expensive than an addition. The question comes down to your Cover home’s existing roofline and foundation, and whether the space you want already exists but is poorly used. We’ll tell you honestly if a reconfiguration serves you better than a new foundation pour, and the consultation costs nothing. Call (682) 708-9180 to schedule a walkthrough.
Most additions run 4 to 8 months from permit approval to final walkthrough, and a full ADU typically runs 5 to 9 months. Permit review time in Fort Worth varies by project type and whether you’re in a historic district like Fairmount, where additional design review applies. We give you a written timeline alongside the written price, and we’ll flag anything likely to slow the job before we start. If you’re trying to plan around a school year or a baby’s arrival, call (682) 708-9180 and we’ll walk through the schedule with you.
We order and manage all materials ourselves, sourced from partners whose warranties you can verify. If you want cabinets from KraftMaid, countertops from Cambria, or plumbing fixtures from Kohler, we’ll spec them into the written price before any work begins. For Cover-specific dimensional matching, we measure every opening and every connection point ourselves before ordering, because we’ve learned not to trust published spec sheets blindly. You never need to pick up a part from our supplier, and you’ll always know what you’re paying for before the crew arrives.
If you’re planning an addition or ADU on your Cover home in Fort Worth, call us at (682) 708-9180 for a free estimate. You’ll get a written price before any work starts, a crew that protects the house like a home, and Graham’s word that the written price and the final invoice should read the same. If they don’t, that’s on us to explain before we hand you a pen.
