Do I need a permit to build a metal building in Horseshoe Bay, TX?

Yes. The City of Horseshoe Bay requires a building permit for any structure over 200 square feet, including detached garages, workshops, and accessory buildings. You must submit engineer-stamped drawings, a site plan showing setbacks from property lines, and pay applicable permit fees through the City of Horseshoe Bay Development Services office. For properties in unincorporated Llano County outside city limits, permitting is handled through Llano County and must comply with Texas state minimum standards administered by TDLR. TMB Construction handles the full permitting process as part of every project — you don't need to navigate this alone. Call 830-289-3852 to discuss your specific property's permitting requirements.

How much does a metal building cost in Horseshoe Bay, TX?

Metal building costs in Horseshoe Bay range from $20–$35 per square foot for a basic shell package (steel frame, panels, roofing, standard doors) to $45–$85 per square foot for a fully finished building with concrete slab, insulation, and electrical. Barndominiums intended as living spaces typically run $90–$130 per square foot with quality interior finishes. Horseshoe Bay's granite bedrock can add $3,000–$8,000 to foundation costs compared to softer-soil sites.

How long does it take to build a metal building in Horseshoe Bay?

For a standard 30×40 to 40×60 metal building in Horseshoe Bay, the construction timeline from signed contract to completed building typically runs 6–12 weeks. This includes 2–4 weeks for permit approval (assuming complete, engineer-stamped submittals), 1–2 weeks for site prep and concrete work, and 2–4 weeks for steel erection and finish work. Larger barndominiums or more complex projects can take 4–6 months. The Hill Country's spring and summer peak season means TMB's schedule fills quickly — property owners targeting a summer project start should contact us by March to secure a slot.

Does TMB Construction handle both city and county permits in the Horseshoe Bay area?

Yes. TMB Construction is experienced working with both the City of Horseshoe Bay Development Services department for in-city projects and Llano County permitting for rural properties outside city limits. We prepare and submit all permit applications, coordinate engineer-stamped plan reviews, and handle any corrections or follow-up requests from the permitting office. From our experience with Hill Country county permitting, having complete documentation — including engineered drawings, site plans, and proof of contractor licensing — is the single biggest factor in avoiding permit delays. We manage this entire process so you can focus on decisions about your building rather than paperwork.

What type of insulation is recommended for a metal building near Lake LBJ?

For metal buildings near Lake LBJ in Horseshoe Bay, spray foam insulation is the highest-performing option and the one TMB most frequently recommends for occupied structures. Closed-cell spray foam at R-19 for walls and R-30 for the ceiling meets ENERGY STAR minimum standards and provides a moisture and air barrier critical in a lakeside environment where humidity fluctuates significantly. For unoccupied storage buildings, vinyl-backed fiberglass batt insulation at R-13 to R-19 is a cost-effective alternative. During Horseshoe Bay's summer highs averaging 96°F, proper insulation can reduce interior temperatures by 30–40°F in an uninsulated metal building — a meaningful difference for any space used regularly.

Can TMB build on a Horseshoe Bay property with granite bedrock near the surface?

Absolutely — shallow granite is one of the most common site challenges we encounter in the Horseshoe Bay and Marble Falls corridor, and TMB has extensive experience designing foundations for these conditions. Depending on depth, options include shallow perimeter-grade beam foundations that bear on the rock, or mechanical excavation and removal of rock in key foundation locations. Shallow granite typically adds $3,000–$8,000 to foundation costs but does not prevent construction. We conduct a site visit before finalizing any estimate so that foundation requirements are accurately scoped — not discovered mid-project.

Does TMB Construction build barndominiums in Horseshoe Bay and Llano County?

Yes, barndominium construction is one of our most requested services in the Horseshoe Bay and Llano County corridor. Our barndominium projects combine steel-frame durability with fully finished residential interiors — spray foam insulation, custom floor plans, HVAC, plumbing rough-in, and finish work from concrete floors to custom cabinetry. A 1,800–2,400 square foot barndominium in this market typically costs $150,000–$240,000 depending on finish level and site conditions. Many Horseshoe Bay clients build barndominiums as lake retreats or investment short-term rentals. Visit our barndominium construction services page at tmbtx.com or call 830-289-3852 to discuss your vision.

Expert Insight from TMB Construction

Justin Torres, Owner — TMB Construction, Burnet TX | 7+ years Hill Country construction experience | Licensed & Insured in Texas | A+ BBB Rating

“In our 7+ years building across the Texas Hill Country, Horseshoe Bay is one of the markets where we see the most clients burned by out-of-area contractors who quote a low shell price and then hit them with surprise costs for engineering, rock excavation, and permits. The granite bedrock along the Lake LBJ corridor is real — it's beautiful country, but it doesn't behave like flat Central Texas soil. We walk every Horseshoe Bay site before we put a number on paper, and we build the engineering and permit fees into every estimate from day one. That's how a $40,000 garage stays a $40,000 garage instead of becoming a $58,000 surprise.”
