Who issues the building permit for a barndominium in Marble Falls?
Across the mile-wide extraterritorial jurisdiction around the city, the city issues no building, electrical or mechanical permits at all. Outside the city limits, including that ring, Burnet County issues the building permit in two classes set by the flood hazard area, and it will not issue the septic permit without the building permit first. Septic is its own question here, because the City of Marble Falls, Burnet County and the Lower Colorado River Authority are all authorized septic agents in this county. Texas does not license builders at the state level, so every builder you talk to is independent. Settle the jurisdiction question before you sign anything. It sets the order of every other step.
The city does, inside the city limits. Marble Falls requires a building permit for all construction there, and new construction is on the city's own list of work needing one. Plans get read against the 2024 International Residential Code with the 2023 National Electric Code, effective from an April 7 adoption. That is a newer code year than the city of Burnet, which runs the 2021 International Residential Code.
Marble Falls also has a one mile extraterritorial jurisdiction. In that ring the city regulates signs, subdivision of land, non-point source pollution and water quality, and it issues no building, electrical or mechanical permits. A lot there is not exempt from permitting. It answers to a different desk.
Outside the city limits, Burnet County Development Services issues the permit in two classes. Class A covers a site clear of any flood hazard area: application and payment, with no county inspection of the structure. Class B covers a site within a designated flood hazard boundary and needs an elevation certificate from a surveyor or a letter from an engineer, a site plan that marks the flood zone, and two inspections, one before the pour and one at finished construction. The order is fixed and the county will not process an incomplete packet: 911 address, then building permit, then septic permit. Compare all six counties in the county-by-county permit page, and see the Burnet County permit page for the rest.

Who permits the septic on a Marble Falls barndominium lot?
One of three agents, and the lot decides which. Burnet County has eight authorized on-site sewage agents: Burnet County, the Lower Colorado River Authority, Cottonwood Shores, Bertram, Burnet, Granite Shoals, Marble Falls and Horseshoe Bay. Granite Shoals is administered by LCRA and Bertram by Burnet County. A city's delegation covers only its incorporated area, so the City of Marble Falls septic authority stops at the city limits.
The river authority zone is what catches people on a lake lot. LCRA regulates on-site sewage facilities within a 2,200 foot zone around the upper Highland Lakes, and Lake Marble Falls is one of the five lakes named in its rules. The zone is two layers: a Restricted Zone at the lake, plus a Water Quality Zone reaching 2,000 feet horizontally past the outer boundary of that Restricted Zone. Inside that jurisdiction a permit is required before any on-site sewage facility goes in, no matter the lot size. Burnet County publishes a link to the river authority map and does not say which lake lots fall inside it, so search your own address on LCRA's jurisdiction map before you plan a drainfield.
Allow up to 30 days from the date the application is submitted for a new system permit, not counting design or site complications. Buying an existing lake place instead of building? An inspection is required on every transfer of ownership before LCRA approves the new owner for continued use. On an aerobic unit a maintenance contract is required for the first two years, and only after that may the owner do the work, once they take the class and pass the test. The installer must be licensed or registered by TCEQ. More in the septic permit guide.

Which other offices sign off before you pour?
Burnet County Development Services also holds the floodplain job, for the Floodplain Administrator appointed by Commissioners Court. That administrator is responsible for making sure development complies with the floodplain rules and other applicable codes, and that permits are applied for. In an A zone the county requires one foot of freeboard above base flood elevation and recommends two. A permit is required before construction or development begins inside any Special Flood Hazard Area. The Elevation Certificate documenting your floor height is certified by a land surveyor, architect or engineer authorized by law. Check the address at the FEMA Flood Map Service Center before you pick the building site, because that answer sets your county permit class.
The driveway is its own approval and it comes early. Your precinct commissioner issues the county road access permit and sets culvert location, length and diameter at a site meeting, and driveway approval has to be in hand before the 911 address is assigned. If the access is onto a Farm to Market road, a Ranch Road or a state highway, TxDOT approves it instead.
Above the lakes there is one more layer. The Highland Lakes Watershed Ordinance covers the Colorado River watershed in Burnet County above the Regulated Pool Elevation, as drawn on the official Ordinance Map, and it reaches buildings, roads, paved storage and parking, plus clearing, excavating, grading, contouring and fill. An LCRA development permit is required if impervious cover will exceed 10,000 square feet and/or land disturbance will exceed one acre. A single family residence under both limits can file a written notification with LCRA instead. Eleven local governments administer part or all of the ordinance under interlocal agreements, so the permit that applies may not be LCRA's. Ask LCRA which office administers the ordinance for your parcel.

What is under a Marble Falls lot?
Rock, and it is not one rock. Burnet County is a core county of the Llano Uplift, a large granite batholith and the major structural feature of central Texas, with Precambrian granites and metamorphic rocks forming the central dome. Limestone is in the mix too: at Inks Lake State Park, on the east edge of the uplift in Burnet County, pink Valley Spring gneiss juts up through the limestone. Nothing in the public record pins the rock under a given Marble Falls lot. Get the tract itself looked at before anyone prices the pad or the septic trench, and ask in writing who carries the overrun if the rock comes in shallow.
If the lot is on a well rather than a utility connection, ask which aquifer it draws from. Two minor aquifers sit in the Llano Uplift area. The Ellenburger-San Saba Aquifer is a minor aquifer in parts of 16 counties there. The Hickory Aquifer is made of the water-bearing parts of the Hickory Sandstone Member, and it carries radionuclides derived from the Precambrian granite of the uplift. That makes testing a question worth asking out loud: ask what the well water was tested for, and read the result before you close.

What does a Marble Falls barndominium lot run into first?
The jurisdiction question, and the three sets of lines behind it do not line up. There is the city limit, the one mile ETJ ring where the city issues no building permit, and LCRA's restricted and water quality zones around Lake Marble Falls. A lot can sit outside the city limits, inside the ETJ, and inside LCRA's septic jurisdiction at once. That puts the building permit at Burnet County, the septic permit at LCRA, and the subdivision and water quality review at the city. Pin down which of the three apply to the exact parcel before you price anything.
Then the ground. A builder's per square foot number covers the building. Septic, driveway, power, water, rock and the pad are priced on the site itself, which is why two lots in the same subdivision do not land in the same place. Ask who carries the risk on rock excavation before you sign. The barndominium cost page explains how that splits.
Then run the sequence in the order the county will accept it: driveway approval signed by your precinct commissioner, then the 911 address, followed by the building permit and, last, the septic permit. Out of order, the packet comes back.

How do you check out barndominium builders in Marble Falls, TX?
You check the trades, because there is no builder license to check. Texas issues no state license for general contracting, though a city or county may still have requirements of its own, and the Texas Residential Construction Commission no longer exists: it was abolished, and its enabling Act lapsed on September 1, 2009. Every builder you talk to here is independent, and the checking is yours to do.
The trade licenses are real and public. Plumbers hold state licenses from the Texas State Board of Plumbing Examiners, which runs a public license lookup. Electricians are licensed by TDLR, non-exempt electrical work must go through a licensed electrical contractor, and licenses are verified in the TDLR license search. Septic installers are licensed or registered by TCEQ, Installer I for standard systems and Installer II for all system types, with a public TCEQ lookup. Ask for the numbers on your subcontractors and run them.
Then ask the jurisdiction questions out loud. Who pulls the building permit on this lot, the city or Burnet County? Which agent permits the septic, the city, the county or LCRA? Has the driveway been walked with the precinct commissioner yet? If the answers come back vague, keep asking until they are not. Start with turnkey barndominium construction, then read building a barndominium in Central Texas for how the whole build sequences.

Lot and permit questions near Marble Falls
Does Marble Falls issue a building permit outside the city limits?
No. Marble Falls has a one mile extraterritorial jurisdiction where it regulates signs, subdivision of land, non-point source pollution and water quality, and it issues no building, electrical or mechanical permits there. Outside the city limits, that ring included, the permit comes from Burnet County Development Services, Class A outside a flood hazard area and Class B inside one.
Who permits the septic on a Lake Marble Falls waterfront lot?
It depends on where the lot sits. Burnet County, the City of Marble Falls and the Lower Colorado River Authority are all authorized agents here. LCRA regulates on-site sewage facilities within a 2,200 foot zone around the upper Highland Lakes, and Lake Marble Falls is one of the five lakes named in its rules, with a permit required inside that jurisdiction whatever the lot size. Burnet County does not say which lake lots fall inside it, so search the address on LCRA's jurisdiction map first.
What building code will my plans be read against in Marble Falls?
Inside the city limits, the 2024 International Residential Code with the 2023 National Electric Code, effective from an April 7 adoption. Outside them the Burnet County Class A permit is application and payment with no county inspection of the structure, and Class B adds an elevation certificate and two inspections, one before the pour and one at finished construction.
Are barndominium builders in Texas licensed?
No. Texas issues no state license for general contracting, and the Texas Residential Construction Commission no longer exists: it was abolished, and its enabling Act lapsed on September 1, 2009. A city or county may still have requirements of its own. The licensed trades are plumbers through TSBPE, electricians through TDLR and septic installers through TCEQ, and those you can verify.
