A home addition in Live Oak typically runs $180 to $340 per square foot for a stick-built room, while a detached ADU off a prefab line like Abodu or Dvele usually lands between $185,000 and $320,000 all-in. Most Live Oak projects we quote are done on a written, fixed price before any work starts, not a verbal estimate that shifts once the walls are open. If you’re planning a second story, a garage addition, or a bump-out on a 1960s ranch near Toepperwein Road or along Pat Booker, we know what your lot, your zoning, and your house will actually require.
Call (430) 258-2928 to schedule a free estimate with our Home Addition Contractor team. We walk the site, check the existing framing and panel, pull the Live Oak code requirements, and hand you a written line-item price before you commit to anything.
Why Benson ADU San Antonio Is Live Oak’s Preferred Home Addition Contractor Company

Live Oak homeowners keep calling us back because we do something most contractors around Bexar County won’t: we name the price and the permit triggers in writing, then hold to both. Troy Eastman, who runs our Live Oak projects, has spent years working through what the city’s zoning ordinance actually requires, which is not the same thing San Antonio requires. A plan approved under San Antonio’s unified development code can get bounced by Live Oak for a side-yard setback issue on a corner lot, and we check for that before you spend a dollar on drawings.
Our crews arrive in uniform, background-checked, and on schedule. When a homeowner off Loop 1604 calls about a sunroom or a bathroom addition, we send a real person to the site within days, not weeks. You’ll know exactly who’s walking onto your property and exactly what that person is there to do. We’re part of the Relay Home Co. family, founded in 2006, and every Live Oak project comes with a 365-Day Done Right Promise in writing.
Second Story Addition Contractor in Live Oak
A Second Story Addition Contractor in Live Oak deals with something most new-construction builders never touch: the 1960s and 1970s ranch frames that dominate this city were not engineered for a second floor, so the job often starts with foundation and shear-wall upgrades before a single joist goes up. In Live Oak, a second story addition usually costs between $220 and $340 per square foot, depending on whether the lower floor needs structural reinforcement and whether the existing electrical service can carry the load. That’s the number we put in writing, not a ballpark we revise after you’ve signed.
Structural Checks Before Framing
Before we price a second story on a Live Oak ranch, we inspect the slab, the existing wall framing, and the panel. Many of these homes have 60-amp or 100-amp services that won’t handle a second HVAC zone, so the electrical upgrade gets written into the contract as a line item, not a surprise change order.
Permit Path and Setbacks
Live Oak applies its own setback rules, including a minimum 5-foot side-yard setback on corner lots. If your addition pushes toward that line, we flag it before drawings are finalized so you’re not paying an architect twice.
Garage Addition Contractors in Live Oak

Garage Addition Contractors in Live Oak spend more time on lot lines and drainage than people expect. Most Live Oak homes sit on lots of a quarter acre or more, which leaves room for a detached garage or a workshop, but the city’s impervious cover limits mean the new roof area has to be matched with drainage that doesn’t send stormwater into the neighbor’s yard. A garage addition in Live Oak typically runs $95 to $180 per square foot for a detached build, with the higher end covering insulation, a subpanel, and finished interior space. We price that in writing before any concrete is poured.
Detached Garage with ADU Potential
A detached garage on a Live Oak lot can double as a future ADU if you get the foundation and rough plumbing in now. Tuff Shed and Plant Prefab both have garage-plus-living configurations that work well on the larger lots here, and we can quote either path.
Attached Garage and House Ties
When a garage ties into the existing house, the connection point matters. Older Live Oak homes often have settled slabs, so we check the elevation difference before framing the tie-in, or you end up with a step where you didn’t plan one.
Trusted Brands We Service in Live Oak
We build with and service prefab systems from Abodu, Dvele, and Plant Prefab, plus Tuff Shed structures and James Hardie siding, because Live Oak homeowners deserve options they can research before they ever call us. When a Live Oak customer chooses a James Hardie plank for a bump-out or a full room addition, we know the product’s exposure limits in hot, humid Texas summers and how it handles hail, which matters on this side of Bexar County. We keep detailed spec sheets and material lead times current for every brand we offer, so your written estimate reflects a real material cost, not a placeholder.
Common Home Addition Contractor Problems We See in Live Oak Homes
- Cloth-wrapped wiring and undersized panels. Homes built in the 1960s and 1970s around Live Oak often still have original 60-amp or 100-amp electrical services, and opening a wall for an addition triggers a code requirement to bring that up to current standards, usually 200 amps.
- Setback confusion between Live Oak and San Antonio. Live Oak has its own zoning ordinance, and a plan that clears San Antonio’s rules can fail Live Oak’s minimum 5-foot side-yard setback on a corner lot, costing weeks of delay if it’s caught late.
- Drainage failures on new roof areas. A new bedroom or garage roof adds impervious cover, and Live Oak’s drainage requirements mean a downspout routed the wrong way floods the neighbor’s yard, which triggers a stop-work order.
- Termite and water damage hidden in old framing. The humid climate around Live Oak pushes moisture into sill plates and rim joists, and on a 1970s ranch, what looks like surface damage is often structural once the drywall comes off.

FAQs About Home Addition Contractor in Live Oak
Yes. Live Oak issues its own building permits and applies its own zoning ordinance, so a bedroom addition permitted under San Antonio rules will still need a Live Oak permit, and the city’s setback and impervious cover limits may differ from what a San Antonio contractor is used to. Call (430) 258-2928 and we’ll check your specific lot before you pay for plans.
Live Oak enforces the adopted editions of the International Residential Code and the International Building Code, plus local amendments covering setbacks, drainage, and electrical service minimums. We verify the exact code edition in effect at permit intake for every Live Oak addition, and we write compliance into the estimate so your submittal passes the first time.
We inspect before we quote, and we include written allowances for the conditions Live Oak homes typically hide: termite damage in rim joists, failed flashing, rotted sill plates, and cloth-wrapped wiring. If a surprise exceeds the allowance, we pause and put the cost in a written change order that you approve before any further work happens. Call (430) 258-2928 for an exact quote on your house.
Rarely. A second story adds a second HVAC zone, more circuits, and smoke and carbon monoxide requirements that typically push an older 60-amp or 100-amp panel to a 200-amp service, and Live Oak will require the upgrade before final inspection. We price that upgrade as a line item in your written estimate, so it’s known before framing begins.
Yes. Live Oak sits in a hail-prone corridor, and your roof and siding choices, including James Hardie cladding and impact-resistant roofing, will need to meet the wind and impact standards the city’s building department enforces. We spec materials that pass Live Oak inspections and hold up through Bexar County storm seasons.
