A home addition in Keller, TX runs $60,000 to $300,000. A single room with no plumbing is $60,000 to $110,000. A room plus a bathroom, such as an in-law suite, runs $110,000 to $190,000. Multi-room, second-story, or kitchen-involved work is $190,000 to $300,000, sometimes more. Scope sets the number, not square footage alone.
Keller is the kind of town families settle into. A lot of the homes we walk here went up in the 1990s and 2000s. They tend to be well built, most of them brick, plenty of them two-story, and a good number sit on lots with more room out back than you get closer to downtown Fort Worth. The house is good. The family just outgrew it.
What a room addition costs in Keller
| Scope | Price range |
|---|---|
| Single room, no plumbing (bedroom, office, den) | $60,000 to $110,000 |
| Room plus a bathroom (in-law or guest suite) | $110,000 to $190,000 |
| Multi-room, second-story, or kitchen-involved | $190,000 to $300,000+ |
What moves a project between tiers is rarely floor area. It is plumbing, roofline, and how much of the existing house has to be opened up. A bedroom off the back of a one-story with a simple roof tie-in is the least involved addition we build. Put a full bath in it and you have added supply lines, a drain run, venting, and another inspection cycle. Touch the kitchen and you are moving gas, electrical, and appliances while the family still has to eat.
We do not publish a per-square-foot number, and you should be careful with anyone who does. Two additions the same size on the same street can land thousands apart depending on foundation, roof, and what is inside the wall we cut into. We price yours after Chris and Xavier walk the house.
Adding on versus buying bigger
School zoning is the reason a lot of our Keller clients build instead of list. Once a family is zoned where they want to be, buying 400 more square feet can mean giving that up or paying a premium to stay in the same boundary. Add commissions on both ends, a new interest rate, and the cost of moving, and the gap between buying bigger and building on closes quickly.
We will not pretend an addition always pencils out. If the foundation has problems, or the house is already at the top of what the street supports, we will tell you. What you get from us is a real number to compare against a real listing.
Going out versus going up
Many Keller lots have room to go out at grade, and that is usually the simpler and lower-cost direction. A ground-floor addition means new foundation, framing, a roof tie-in, and extending HVAC. A second story means all of that plus proving the existing foundation and walls can carry the load, opening the roof, and living through a stretch with tarps over your house.
We want a structural engineer involved before anyone puts a firm number on second-story work. A price given without one is going to move. When your lot can absorb the footprint, going out is simpler and lower risk. When it cannot, we will build up, and we will be straight about what that adds.
Brick is the other thing to plan for. On a home built in the late 1990s or 2000s, an exact match is often not possible. The original run may be out of production, and the brick on your house has weathered years of Texas sun. We source the closest match and show you the sample, or we design a break into the elevation so the transition reads as intentional. Better to have that talk in the driveway than after the mortar cures.
HOA review, setbacks, and permits
Many Keller neighborhoods have an HOA with an architectural review committee. Before we frame anything you will likely need their approval, and they will want a site plan, elevations, and material selections. That runs on their calendar, not ours, so start it early. Our crews typically start 1 to 2 weeks out depending on the schedule, but nobody starts before the paperwork clears.
Work inside Keller city limits is permitted and inspected by the city, and setbacks and lot coverage depend on your zoning district and your plat. Check that first on a rear addition, because an existing patio slab or an easement can eat into the footprint you thought you had. Permits are billed at cost. They are not buried in the quote and we do not mark them up.
Garage conversions
We do them, and they are quoted under the same tiers above. A garage conversion is real construction. The slab usually has to come up to floor level, and the space needs insulation, drywall, HVAC that can carry the load, and egress that passes inspection.
Two cautions. Some HOAs will not allow a street-facing garage door to be removed, so read your covenants before you commit to the idea. And you are trading covered parking and storage for living space, which can show up at resale on a street where most houses still have a garage. Plenty of families decide it is worth it. Just decide it on purpose.
If the addition includes a bathroom
A bathroom inside an addition is priced inside the addition tier, not billed on top of it. How we build it is the same either way: Schluter waterproofing on every shower, Delta or Moen fixtures, frameless glass. The detail is on our Keller bathroom remodeling page.
