A home addition in Fort Worth typically runs $120 to $350 per square foot depending on scope, finishes, and whether you go site-built or prefab, according to our Fort Worth Home Addition Contractor pricing. That’s the honest range, and it’s the number most contractors won’t give you until you’ve sat through three sales pitches. We’re Benson ADU Fort Worth, led by Troy Eastman, and we’ve been building additions since 2006 under The Relay Visibility Guarantee: a written price before work starts, real-time tracking, and a 365-Day Done Right Promise on every project we take on.
Adding square footage to your home is the single biggest value decision most Fort Worth homeowners make. You deserve a contractor who answers the phone (a live person, 24/7), shows up in uniform, and puts every number in writing before the first shovel turns. Call us at (682) 204-9686 and you’ll have a real conversation with someone who knows setbacks, prefab panel lead times, and what Fort Worth’s clay soil means for foundation work.
Key Takeaways
- Written price before work starts: no verbal estimates that shift, no change orders slipped in after demo day.
- 365-Day Done Right Promise: if the work isn’t right within a full year, Benson makes it right. In writing, on every project.
- Prefab and site-built options: we build with Abodu, Cover, Dvele, Mighty Buildings, and Boxabl, plus James Hardie cladding, giving you choices you can research independently.
- Transparent process: live arrival times, before-and-after photos, digital invoices payable by link.
- Background-checked, uniformed technicians on every job site, so you always know who’s walking onto your property.
Sunroom Addition
Sunroom Addition is what Fort Worth homeowners ask for when they want light, air, and extra living space without the budget of a full room addition. A sunroom typically costs $25,000 to $75,000 in this market depending on size, glazing, and whether it’s a three-season or four-season build. Benson ADU Fort Worth handles the full scope: permits, slab or deck foundation, framing, insulated glass, HVAC tie-in if you want year-round comfort, and finish work.
Foundation and Climate Considerations
Fort Worth’s clay soil expands and contracts with moisture, which means sunroom foundations need proper piers or slab reinforcement. We account for this from day one, and our written price includes soil evaluation so you’re not surprised by a shifting floor five years down the road.
Prefab vs. Site-Built Sunrooms
We offer both. A prefab sunroom using panelized systems from brands like Cover or Dvele goes up faster and with less on-site waste. A site-built sunroom gives you more flexibility on dimensions and roofline matching. Either way, you get the written price first.
Second Story Addition Contractor
Second Story Addition Contractor is the search homeowners make when they’ve got a footprint problem: the lot won’t allow a sideways expansion, but the family needs more bedrooms or a dedicated workspace. Adding a second story in Fort Worth runs $180 to $400 per square foot, with the higher end reflecting structural reinforcement, stairwell construction, and roofline reconfiguration. Benson ADU Fort Worth has built these additions since 2006.
Structural Reality of Going Up
Most single-story Fort Worth homes were never engineered to carry a second floor. That means we assess the existing foundation, framing, and lateral bracing before quoting anything, and our written price includes the structural upgrades the code requires. You won’t get a surprise “additional engineering” invoice mid-project.
Prefab Second Story Panels
Brands like Mighty Buildings and Boxabl now offer factory-assembled wall and roof sections that can cut weeks off a second story build. We’re authorized to build with these systems, and we’ll show you side-by-side pricing so you can decide whether speed or customization matters more for your project.
Garage Addition Contractors
Garage Addition Contractors in Fort Worth build three common things: attached garages, detached garages, and garage conversions with or without an ADU on top. As our Home Addition Contractor in Bedford team often explains, these projects vary widely in scope. A new attached two-car garage typically runs $35,000 to $65,000, a detached garage $45,000 to $90,000, and a garage-to-living-space conversion $60,000 to $120,000 depending on plumbing, insulation, and finish level. Benson ADU Fort Worth quotes all three with a written price.
Setback Rules and Lot Lines
Fort Worth zoning sets minimum setbacks from property lines, and an attached versus detached garage changes what’s allowed. We handle the survey, the permit application, and the inspections, and we explain every requirement in plain English before you sign anything. A setback is simply the distance a structure must sit from your property boundary, and we make sure your garage clears it.
Garage ADU Stacks
If you’re adding a detached garage anyway, stacking an ADU above it is one of the highest-ROI moves a Fort Worth homeowner can make. We build these using prefab panels from Cover or Dvele, which arrive pre-cut and go up in days rather than months. You get parking below and a rentable unit above.
Bathroom Addition Contractor
Bathroom Addition Contractor work in Fort Worth means running new water lines, waste lines, venting, and waterproofing where none existed before. A mid-range bathroom addition runs $28,000 to $55,000, and a high-end primary bath with custom tile and a curbless shower can reach $80,000. Benson ADU Fort Worth gives you a written line-item price so you know exactly where each dollar goes.
Plumbing and Permit Realities
Fort Worth requires permits and inspections for any new plumbing branch. We pull the permits, schedule the inspections, and include the cost in your written estimate. No “we’ll handle that later” or “you should probably call a plumber separately.” Our team is background-checked and uniformed, and the plumber on your job is the same person every day.
Waterproofing Standards
This is where cheap bathroom additions fail. We use full waterproofing systems behind tile, not just green board and hope. If water gets through, we’re back within the year to fix it under our 365-Day Done Right Promise, in writing, at no charge to you.
Bedroom Addition Contractor
Home Addition Contractor - Haltom City projects often include bedroom additions, which in Fort Worth are usually one of three things: a ground-floor bedroom for aging parents, a nursery or kids’ room, or a dedicated guest suite with its own entrance. Expect $150 to $300 per square foot for a standard bedroom addition, with the higher end reflecting closets, en-suite plumbing, and HVAC extension. Benson ADU Fort Worth quotes the full scope, not a teaser number.
HVAC Load and Comfort
Every new bedroom changes your home’s heating and cooling load. We calculate the Manual J load before we quote, which means your written price includes the right-sized ducting or a mini-split, not a guess that leaves the new room freezing in February and roasting in August.
Adding a Rental-Ready Bedroom Suite
If the bedroom has its own bath and entrance, Fort Worth zoning may treat it as an accessory dwelling unit, which opens up rental income potential. We’ve built these with Boxabl prefab modules and with traditional framing, and we’ll walk you through which option fits your lot and your budget.
Brands We Service
We’re authorized to build with Cover prefab panel systems, and we’ve completed multiple Cover ADU and addition projects across the Fort Worth market. Their panelized wall and roof sections arrive pre-engineered, and we handle the site work, foundation, and finish trades so the panels click into a completed room, not a construction site.
We also build with Dvele and Mighty Buildings modules for homeowners who want a factory-built shell with the highest insulation and air-sealing standards available in prefab today. And for budget-conscious detached additions, Boxabl offers a compact, repeatable module that’s ideal for a home office or guest suite. Whether you’re interested in one of these brands or want a traditional site-built addition framed on your lot, we’ll give you honest side-by-side pricing and a written guarantee either way.
Signs You Need a Pro Right Now
- Your family has outgrown the floorplan, not the furniture. If you’re rearranging rooms every season or someone’s sleeping in a converted dining room, you’re past the point where decluttering helps. A home addition in Fort Worth is the permanent fix, and our written estimate tells you exactly what permanent costs.
- You’re renting storage space for things your house used to hold. Fort Worth storage units run $80 to $150 a month, which is $1,000 to $1,800 a year for stuff you actually need. That money could be going toward equity in an addition instead.
- You’ve looked into moving, and the numbers don’t work. Between 6% realtor commissions, closing costs, and the price jump on a bigger house, many Fort Worth homeowners find that adding 400 square feet beats selling by a wide margin. We’ll price the addition and you can compare it against the moving quote yourself.
- Your mortgage rate is way lower than today’s market. If you locked in at 3% and current rates are pushing 7%, selling and rebuying means paying double the interest on the entire loan amount. An addition financed through a HELOC or cash-out refi keeps your good rate intact.
- An aging parent or adult child needs to live with you, not near you. Multi-generational living is growing fast in Fort Worth, and a properly permitted addition with its own entrance and bath costs far less than assisted living or a separate rental. We handle the permits and the privacy design.

How Much Does Home Addition Contractor Cost in Fort Worth?
Here’s the straight answer: a standard single-room addition in Fort Worth typically runs $30,000 to $80,000, a primary suite addition $60,000 to $120,000, and a second story addition $120,000 to $250,000 depending on structural work. Prefab options from Cover, Dvele, Mighty Buildings, or Boxabl can shift the timeline and sometimes the price, and we’ll show you both. A detached ADU built above a new garage, which is a home addition strategy we also build in nearby Euless, lands in the $150,000 to $250,000 range.
What moves the price: foundation scope (slab, crawl space, or pier), plumbing rough-ins, electrical panel capacity, HVAC extensions, and finish level. Fort Worth’s clay soil means foundation costs here run slightly higher than in areas with sandier ground. The best way to avoid overpaying is to get a line-item written estimate, which is exactly what we give every homeowner from the first conversation. The estimate includes the full scope, the permit fees, the materials, and the labor. If the job changes, the price changes in writing before the work changes on site, never after.
