Hood County is one of the more confusing markets in North Texas to permit a custom home in, because the rules genuinely change depending on which side of a line your lot falls on. I have been building across Granbury and the surrounding Hood County acreage for over thirty years, and the question I get asked most by clients moving out from Fort Worth or Arlington is some version of "wait, who actually approves this." Here is the honest answer, lot type by lot type.
What's the Permit Process for Building in Hood County?
It splits three ways. Inside Granbury city limits, you need a full building permit reviewed and issued by the City of Granbury's Building Inspections, Permits, and Code Enforcement department, with plan review and staged inspections just like any incorporated Texas city. On unincorporated acreage outside the city, Hood County does not run a general building permit or code enforcement program, but you still need a septic permit, an address assignment, and sometimes a flood development permit. Inside gated lake communities like Pecan Plantation or DeCordova Bend, you layer a private HOA architectural review on top of whichever government permit applies to that parcel.
Does the City of Granbury or Hood County Permit Your Build?
The short version: it depends entirely on whether your address falls inside the Granbury city limits or out in unincorporated Hood County. Granbury runs permitting through its Building Inspections, Permits, and Code Enforcement office at City Hall, with applications submitted through an online OpenGov portal. The city reviews plans against the adopted building code, issues the permit, and schedules inspections at framing, mechanical rough-in, and final, the same staged process you would expect in Fort Worth or Weatherford.
Step outside the city line onto unincorporated Hood County acreage and the picture changes. Texas counties, Hood included, generally do not have the statutory authority to run a general residential building code the way cities do. That surprises a lot of buyers coming from a city background, but it does not mean the build is unregulated. It means the regulation shifts to a handful of specific permits rather than one blanket building permit.
What Permits Do You Actually Need Outside City Limits?
On unincorporated acreage, the permit that actually gates your build is the on-site sewage facility permit, what most people call a septic permit, issued through the Hood County Environmental Health Department. Their process requires a completed application, a to-scale system design, and a current plat or survey showing the legal description and lot size, and their stated turnaround is about five business days once a complete application is submitted with no site problems, longer if the soil or layout needs more review. You will also need a 911 address assignment before the septic application moves forward, and a flood development permit if any part of your building envelope sits in a mapped floodplain, which comes up often on lots closer to Lake Granbury's shoreline.
If your acreage is not served by a community or municipal water system, add a well permit through the groundwater conservation district covering your parcel. We confirm the correct district and start that process early, since drilling and permitting a well can run on its own timeline separate from the house.
| Lot type | Permitting authority | Building permit required | Septic / water | HOA review |
|---|---|---|---|---|
| Inside Granbury city limits | City of Granbury | Yes, full plan review and staged inspections | City water/sewer where available | Only if in a platted subdivision with a HOA |
| Unincorporated Hood County acreage | Hood County (limited scope) | No general building permit | County OSSF septic permit; well permit if not on community water | Rare, unless deed-restricted |
| Gated lake community (Pecan Plantation, DeCordova Bend) | County permits plus HOA | Varies, often county-only | County septic/well or community system | Yes, architectural committee review |
| Near the historic courthouse square | City of Granbury, preservation review | Yes, plus Certificate of Appropriateness | City water/sewer | Only if also in a platted HOA |
What About Lake Granbury Communities Like Pecan Plantation?
Waterfront and near-water lots around Lake Granbury are a different conversation entirely. We have built in coves around Pecan Plantation, on open-water lots near DeCordova Bend, and on cliff-style sites along the north shore, and each one carries its own setback, dock easement, and drainage questions tied to Brazos River Authority rules governing the lake. On top of whatever county permit applies to that parcel, Pecan Plantation, DeCordova Bend Estates, and DeCordova Ranch each run their own architectural committee that reviews materials, rooflines, and setbacks before you ever break ground. We design to those standards from the first sketch rather than fighting the committee after the fact, because a redesign after HOA rejection costs real weeks on your schedule.
How Long Does Permitting Take in Hood County?
On unincorporated acreage, the septic permit is usually the long pole, five business days if everything is submitted clean, longer if the site needs an alternative system or additional soil evaluation. Add the 911 address assignment and, if relevant, a flood development permit, and most acreage permitting wraps inside three to five weeks before site work starts. Inside Granbury city limits, plan review timelines run closer to what you would see in any Texas city, generally a few weeks for a full plan review cycle, plus whatever HOA review runs in parallel if your lot is also in a gated or platted community. Either way, this permitting window sits inside the 3 to 6 months of design and permitting we build into every project before the 12 to 14 month construction schedule begins.
What Should You Check Before You Buy Land in Hood County?
Before you fall in love with a lot, confirm three things: whether it sits inside or outside Granbury city limits, whether it carries deed restrictions or HOA architectural review, and whether it has a path to water, either a community system or a buildable well. I have had clients assume a lake-adjacent address meant city utilities, only to find out their specific parcel sits on well and septic in unincorporated county land. Pull the actual appraisal district record for the parcel rather than relying on the mailing address, since Hood County addresses do not reliably tell you which jurisdiction governs your build.
If you are weighing Hood County against other nearby markets, Cresson sits at the meeting point of Parker, Hood, and Johnson counties with its own mix of permitting authorities, Mineral Wells and Palo Pinto County carry more rugged terrain considerations, and Weatherford remains the most straightforward county-permitted market in the region if you want to avoid lake-community HOA layers altogether.
What Should You Do Next?
If you own Hood County land already or are evaluating a lot near Lake Granbury, the permitting path is exactly the kind of thing worth confirming before you close, not after. I walk every lot in person before we talk numbers, and that walk tells us which permits actually apply to your specific parcel. Call me directly at (817) 736-6323 or request a free consultation, and if you already own acreage, our custom homes on acreage page covers the site work side of the process in more detail. For general land-buying steps before you get to permitting, see our guide on how to buy land for a custom home in Texas step by step.
You can review Hood County's septic permitting procedures directly through the Hood County Environmental Health Department, and confirm City of Granbury building permit requirements through the Permits, Inspections, and Code Enforcement department.
