AfterHow Much Does Construction Cost in San Antonio?
Most homeowners in San Antonio spend between $90,000 and $220,000 on a full-scale construction project like an ADU or major addition, while smaller remodel projects typically run $9,000 to $45,000 depending on scope. A kitchen remodel averages $14,000 to $45,000, a bathroom remodel runs $9,000 to $28,000, and a roof replacement lands between $8,000 and $20,000. The final number depends on square footage, material grades, permit requirements, and the age of your home’s existing structure.
What follows is a real, line-by-line breakdown of what San Antonio contractors actually charge in 2026. No vague “it depends” hand-waving. Just dollar ranges you can plan around before you pick up the phone.

Two big levers move every one of these numbers. First, material grade: a KraftMaid or Wellborn cabinet run costs more than stock cabinetry, but the door alignment and drawer glide quality hold up for decades instead of years. Second, what’s hiding behind the walls. In older San Antonio neighborhoods like Jefferson and Monte Vista, we regularly open walls on 1950s-era homes and find cast-iron drain lines or cloth-wrapped wiring that must be brought to code before new finishes go in. That work isn’t optional, and it isn’t free. A good contractor flags it in the written estimate. We always do.
What Affects Construction Pricing in San Antonio
- Foundation type and soil conditions. San Antonio sits on expansive clay soil. Homes in areas like the northwest side and parts of Helotes experience more slab movement than homes on the denser soils near downtown. If a renovation exposes foundation cracks, repair work adds $3,000 to $15,000 depending on severity. A contractor who knows San Antonio dirt won’t skip this inspection.
- Home age and existing systems. Homes built before 1980 in areas like Harlandale and Edison often have galvanized plumbing and undersized electrical panels. Upgrading a 100-amp panel to 200-amp adds $2,500 to $5,000. Replacing galvanized supply lines in a single bathroom runs $1,500 to $4,000. These are code-driven costs that surface during demolition, not optional upgrades.
- Permit and inspection fees. The City of San Antonio requires permits for structural work, electrical, plumbing, and mechanical changes. Permit costs typically range from $500 to $3,000 on a remodel and $2,000 to $8,000 on an addition or ADU. These fees are paid to the city, not the contractor, but they belong in any honest estimate up front.
- Material grade and availability. Cambria and Silestone quartz countertops run higher than entry-level quartz, but the color consistency and warranty terms differ meaningfully. The same logic applies to GAF versus budget shingles on a roof replacement. Material pricing in San Antonio has stabilized since the 2021-2022 volatility, but specialty items still carry 2 to 6 week lead times from local suppliers.
- Labor depth on the crew. A project that needs a master plumber, a licensed electrician, a tile setter, and a finish carpenter will cost more per day than a simple swap-out. That is not a contractor padding the bill. That is the real cost of sending licensed, background-checked tradespeople to your door, every one of them in uniform and carrying a photo ID badge under the Threshold Standard.
- Access and site conditions. A bathroom on a third-floor Alamo Heights home with a narrow stairwell costs more to demo and haul than a ground-floor bathroom with direct exterior access. Disposal fees in Bexar County run $400 to $1,200 per dumpster load. Tight access means more trips, which means more cost. A good estimate accounts for this before demolition day.
How to Save on Construction
Saving money on construction in San Antonio is less about finding the lowest bid and more about avoiding rework. The cheapest contractor is often the one who does it twice. Here is how to keep costs down without cutting corners:
- Get a written price before work starts. A verbal estimate is not a price. A written price locks the scope and the dollar amount. At Mason Remodeling Co San Antonio, every project receives a written price before a single tool is unpacked. That is the standard, not an upgrade.
- Plan the full scope before demolition. Changing your mind after the drywall is open is the single most expensive habit in remodeling. Moving a drain line mid-project adds $1,000 to $3,000. Decide on fixtures, finishes, and layout during design, not during construction.
- Phase the project thoughtfully. If a full kitchen and bath remodel stretches the budget, do them sequentially rather than simultaneously. Two smaller projects with clean scopes cost less than one sprawling job where crews step over each other.
- Choose materials for the long term, not the trend. A Kohler or Moen fixture with a documented warranty may cost more at the counter but lasts longer than a no-name faucet that fails in year two. The same applies to GAF and CertainTeed roofing versus bargain shingles. Buying twice is always more expensive.
- Ask about the guarantee before you sign. A contractor who will not state what is covered, what is excluded, and for how long is telling you something about their confidence in the work. Mason Remodeling writes the guarantee terms plainly, including the 365-Day Done Right Promise: if the work is not right within a year of completion, we make it right at no cost to you.

FAQs – Construction Cost
How much does a home addition cost in San Antonio?
A home addition in San Antonio typically costs $45,000 to $130,000 depending on whether you are adding a bedroom, a primary suite, or a full living space with plumbing. At the low end, a simple bump-out without plumbing starts around $45,000. A full primary suite addition with a bathroom lands between $80,000 and $130,000. Foundation work on San Antonio’s expansive clay soil is a significant cost driver here. Call (254) 269-5071 for an exact quote on your addition. Estimates are free.
How much does an ADU cost in San Antonio?
An accessory dwelling unit (ADU) in San Antonio runs $90,000 to $220,000. A detached one-bedroom ADU with a small kitchen and bath starts around $90,000 to $120,000. A two-bedroom unit with higher-end finishes and separate utility connections can reach $220,000. San Antonio’s 2023 zoning updates made ADUs easier to permit in many residential neighborhoods, but utility tie-in fees and foundation requirements still drive the cost. Call (254) 269-5071 for an exact quote. Estimates are free.
Is it cheaper to remodel or build new in San Antonio?
In San Antonio, remodeling costs $90 to $250 per square foot depending on scope, while new construction runs $150 to $300 per square foot. Remodeling is usually cheaper per square foot, but that math changes if the existing structure needs extensive foundation repair, rewiring, or pipe replacement. On a 1950s home in Jefferson or Edison, hidden condition issues can narrow the gap quickly. A thorough written estimate from a contractor who knows San Antonio building stock is the only way to compare the two options fairly.
How much does a kitchen remodel cost in San Antonio?
A kitchen remodel in San Antonio costs $14,000 to $45,000 for most homes. A small kitchen with stock cabinets and laminate countertops can be done for $9,000 to $20,000. A mid-range remodel with KraftMaid or Wellborn cabinetry, Cambria or Silestone quartz counters, and a reworked layout runs $30,000 to $45,000. Cabinet installation alone is $4,000 to $13,000. Countertop installation adds $2,000 to $6,500. Call (254) 269-5071 for an exact quote. Estimates are free.
