Hood County

Granbury

Granbury is the one town in this corridor that is in Hood County rather than Parker or Tarrant, which means a different county office answers every rural question — a different environmental health department for septic, a different development office for floodplain, a different appraisal district. It is also the town built around a lake, and a lake changes what a flood-map check is for.

One honest gap leads this page: the city's building page does not name the code editions it inspects to. That is not a criticism, it is the state of the published information, and it means the edition has to be asked for rather than looked up.

We will go up to 45 miles from Fort Worth.

Different county, different answers

Granbury is the only town in this corridor in Hood County, and that changes the whole rural side of a project. A different development office administers subdivision and floodplain regulation, a different environmental health department permits septic, a different appraisal district holds the parcel record. Rules learned in Parker County do not transfer.

Hood County Development administers the county's development, subdivision and floodplain regulations — and states that the county does not issue permits or perform inspections related to residential home construction or remodeling.2 So on unincorporated land here, as across this corridor, no building department looks at the house. See Who issues your building permit.

The city does not publish its code edition

Granbury states that it inspects to codes with the regional council's amendments, Option B, and schedules inspections through its permit portal. Read on 10 September 2026, its page named no code edition.1

We are saying that plainly because it is the state of the published information, and because our own fact register previously asserted specific editions for Granbury that the page does not support — a claim corrected on 10 September 2026 once somebody opened it. Ask the city for the ordinance number and the edition, in writing, with the permit application. Every neighboring town names a specific edition and they are several years apart, so this is not a detail to assume. Which electrical code applies to your lot shows the spread.

Septic, and the two words people miss

Hood County Environmental Health is the on-site sewage permitting office for unincorporated Hood County, and a permit is required for all installation, modification and replacement.3

Modification and replacement are the words that catch people. Adding a bedroom or a casita, or replacing a failed component, is a permit event rather than a maintenance event — the most commonly missed permit in a rural remodel. And an aerobic system brings an ongoing obligation of its own: Living with an aerobic septic system.

Wells: two numbers that can decide the house position

The Upper Trinity Groundwater Conservation District covers this ground, and its spacing rules are specific: a well must be drilled at least 50 feet from the nearest property line and at least 150 feet from any other registered well.5

On a narrow lot, or one ringed by neighbors who already have wells, that arithmetic — not the acreage — can be the binding constraint on where the house can sit. It is worth resolving before a plan is drawn, and it interacts with septic setbacks; Site placement and orientation covers how those constraints stack.

The lake

Lake Granbury is on the Brazos River about 8.3 miles southeast of the city, and the Brazos River Authority owns it.4

Two consequences. Any lot on the lake or on a creek draining to it deserves a FEMA flood-map lookup before a plan is drawn, and a surveyor's elevation certificate where the lot touches a mapped zone. And shoreline questions — what may be built near the water, and on whose land — belong to the river authority and the title company. A builder's opinion is not the answer to a shoreline question.

The numbers

Population, income, home values and commute times are published by Census QuickFacts for both Granbury city and Hood County, and on 10 September 2026 both served July 1, 2025 (V2025) estimates.67 On a lake town the county figure and the city figure often tell different stories, which is why both are linked.

Questions people ask

Which code editions does Granbury inspect to?
The city states that it inspects to codes with the regional council's amendments, Option B, and schedules inspections through its permit portal — but read on 10 September 2026 its page named no edition. So the answer has to come from the city. Ask for the ordinance number and the edition with the permit application, in writing. Every neighboring town in this corridor names a specific edition and they are several years apart, so this is not a detail to assume.
Who permits a house outside the Granbury city limits?
No building department does. Hood County Development administers the county's development, subdivision and floodplain regulations and states that the county does not issue permits or perform inspections related to residential home construction or remodeling. What the county does permit is on-site sewage, through Environmental Health, and development in mapped flood hazard areas.
What does the septic permit involve in Hood County?
Hood County Environmental Health is the permitting office for unincorporated Hood County, and a permit is required for all installation, modification and replacement. Note those last two words: adding a bedroom or a casita, or replacing a failed component, is a permit event rather than a maintenance event, and it is the most commonly missed permit in a rural remodel.
Does the lake affect where I can build?
It can. Lake Granbury is on the Brazos River about 8.3 miles southeast of the city, and the Brazos River Authority owns it. Any lot on the lake or on a creek draining to it deserves a FEMA flood-map lookup before a plan is drawn, and a surveyor's elevation certificate where the lot touches a mapped zone. Shoreline questions — what may be built near the water, and on whose land — belong to the river authority and the title company, not to a builder.
What are the rules for a well?
The Upper Trinity Groundwater Conservation District covers this ground, and two of its numbers decide well placement: at least 50 feet from the nearest property line and at least 150 feet from any other registered well. On a narrow lot, or one surrounded by neighbors who already have wells, that arithmetic can be the binding constraint on where the house sits.
