Understanding Texas Building Permits

A building permit is an official government authorization that allows construction, renovation, or demolition to proceed on a specific property. In Texas, permit requirements are governed at the local level under authority granted by the Texas Local Government Code, Chapter 214, and must align with the International Building Code (IBC 2021) and International Residential Code (IRC 2021) as adopted by the state. The Texas Department of Licensing and Regulation (TDLR) oversees licensed contractors but does not issue residential building permits directly — that responsibility falls to counties and municipalities.

Permits exist to protect property owners. Inspections tied to the permit process verify that structural framing, electrical, plumbing, and mechanical systems meet minimum safety standards. In Burnet County, unpermitted structures can create serious title issues when you attempt to sell or refinance, and lenders increasingly require proof of permitted work before closing. From our experience with Burnet County permitting, structures built without permits are also excluded from certain homeowner's insurance claims, which is a risk no Hill Country property owner should take.

In unincorporated Burnet County, a building permit is generally required for any new structure exceeding 200 square feet, any addition to an existing home, structural remodels that affect load-bearing walls or the roofline, and new electrical, plumbing, or mechanical systems. This covers the vast majority of projects TMB Construction handles — custom homes, barndominiums, metal buildings, garages, and covered patios attached to a residence.

Projects that typically do NOT require a permit in unincorporated Burnet County include repairs and replacements in kind (like-for-like roofing with no structural changes), detached storage sheds under 200 square feet, fencing not attached to a structure, and basic landscaping. However, if your property falls within city limits — Burnet city, Marble Falls, Bertram, or Lampasas — the thresholds and requirements differ. The City of Marble Falls, for example, requires permits for any structure over 120 square feet. Always verify with the relevant jurisdiction before breaking ground.

The Burnet County permitting process runs through the Burnet County Judge's office located at 220 S. Pierce St., Burnet, TX 78611. For projects within city limits, you'll apply through the respective city's building department. Here is the standard sequence for an unincorporated county project:

First, prepare your site plan drawn to scale showing property boundaries, setbacks, and proposed structure placement. Burnet County requires a minimum 25-foot front setback and 10-foot side setbacks for most residential zones, though deed restrictions or HOA rules may impose stricter requirements. Second, submit construction drawings — for a residential structure, these typically include a floor plan, foundation plan, framing plan, and elevation views. Third, pay the permit fee, which is calculated based on project valuation. Fees in Burnet County typically range from $150 for minor projects to $800 or more for full custom home builds. Fourth, await plan review, which takes 5 to 15 business days depending on submission volume. Once approved, your permit is issued and must be posted on-site before any work begins. In our 7+ years building across the Hill Country, we've found that complete, accurate submittals cut review time nearly in half.

Permit fees in Central Texas vary significantly by jurisdiction and project type. Understanding the fee structure upfront helps you budget accurately and avoid surprises. Based on our projects across the region, here is a realistic breakdown of what property owners pay in 2026:

In unincorporated Burnet County, residential permits typically cost $150 to $500 for additions and $300 to $800 for new homes, calculated at roughly $0.10 to $0.20 per square foot of construction valuation. The City of Marble Falls uses a valuation-based table starting at $75 for small projects and scaling to $1,200+ for large custom homes. Liberty Hill, now part of rapidly growing Williamson County, charges $500 to $1,500 for new residential construction reflecting higher administrative demand. Lampasas city permits generally run $200 to $600 for residential work.

Beyond the base permit fee, budget for inspection fees ($50 to $150 per inspection, with typically 3 to 5 inspections required per project), plan review fees (often 25% to 50% of the permit fee), and any required engineering stamps ($400 to $1,200 for a PE-stamped foundation plan). Total permitting costs on a 2,000-square-foot custom home across the Hill Country typically run $800 to $2,500 all-in.

A building permit is only the beginning. The inspection process is what actually verifies your project complies with adopted codes — and in Burnet County and surrounding areas, that means alignment with the IRC 2021 for residential construction and IBC 2021 for commercial structures. Most residential projects in this region require three to five inspections at defined milestones.

The standard inspection sequence includes a foundation inspection before concrete is poured, a framing rough-in inspection after all structural framing and rough mechanical, electrical, and plumbing are complete but before walls are closed, an insulation inspection (ENERGY STAR-qualified insulation requires R-30 in ceilings and R-13 in walls minimum for Central Texas climate zone 2B), and a final inspection confirming completed work matches approved plans. In Burnet County, inspections are scheduled through the county office and typically happen within 2 to 5 business days of request during non-peak periods. During spring and summer peak construction season — March through August — expect 5 to 10 business day waits. TMB Construction coordinates all inspection scheduling on behalf of our clients, so projects stay on timeline.

Barndominiums and metal buildings present unique permitting considerations that many general contractors — and even some county offices — handle inconsistently. In our experience building barndominiums across Burnet, Llano, and Lampasas counties, the classification of the structure drives permit requirements significantly. A metal building used purely for agricultural storage on a working farm may qualify for an agricultural exemption under Texas Property Code and require no county permit in unincorporated areas. However, the moment that structure includes a living space, bathroom, kitchen, or is intended for residential occupancy, it must be fully permitted as a residence.

For residential barndominiums, the IRC 2021 applies in full, including requirements for minimum ceiling heights (7 feet in habitable spaces), egress windows (minimum 5.7 square feet net clear opening), smoke and carbon monoxide detectors, and proper insulation meeting climate zone 2B requirements. Metal Building Manufacturers Association (MBMA) certified building systems — which TMB Construction sources and installs — streamline the plan review process because they come with pre-engineered documentation. Permit fees for a 1,800- to 2,400-square-foot barndominium in Burnet County typically range from $400 to $900. Call 830-289-3852 to discuss your specific barndominium project.

In 7+ years of building across the Hill Country, TMB Construction has seen property owners and even some contractors make the same permitting mistakes repeatedly. Understanding these pitfalls in advance protects your investment and your timeline.

The most common mistake is starting work before the permit is issued. Texas law is clear: construction cannot begin until the permit is posted on-site. Violations result in stop-work orders and can require demolition of completed work to allow inspection of hidden systems. The second mistake is pulling the wrong permit type — for example, pulling a commercial permit for an agricultural building that's actually a residence, or vice versa, creating code compliance gaps. Third, many owners underestimate project valuation on permit applications to reduce fees, which is fraud and can void your permit entirely if discovered during inspection. Fourth, failing to call for inspections at required milestones — especially the framing rough-in inspection — can require opening finished walls at significant expense. Fifth, not verifying deed restrictions before submitting permits. Many properties along Highway 29 between Burnet and Liberty Hill and around Lake LBJ in Horseshoe Bay have HOA or deed restriction requirements that go beyond county minimums.

One of the most tangible advantages of working with TMB Construction is that we manage the entire permitting process in-house — from initial jurisdiction research through final inspection sign-off. Because we self-perform our core work rather than relying on subcontractors, we have direct control over inspection scheduling and can respond immediately when an inspector flags an item.

For every project, our process begins with a pre-permit consultation where we identify the correct jurisdiction, confirm setback requirements, and review any deed restrictions or HOA rules that apply to your specific parcel. We prepare or coordinate all required construction documents, submit the application, pay fees on your behalf (reimbursed at project close), and track review status. Based on our projects in Burnet County, clients who hire us versus managing permitting themselves typically save 3 to 6 weeks on project start dates simply because we know exactly what each jurisdiction wants to see in a submittal. Our A+ BBB rating and 4.9-star Google rating reflect a track record of projects delivered on time and fully compliant.
