Do you need a building permit in Brazoria County, Texas?

Unincorporated Brazoria County requires a building permit for any new or relocated structure over 200 square feet, manufactured homes, and additions worth more than half the existing structure's value1. For new single-family houses and duplexes begun after September 1, 2009, and additions increasing square footage or value by more than 50 percent, the county requires substantial conformity with the 2006 International Residential Code as amended2. Covered new houses and duplexes receive at least three inspections as applicable: foundation before concrete, framing and mechanical systems before wall covering, and completion; the builder contracts with an authorized inspector and submits the final compliance notice to the Floodplain Administrator within 10 days3. Qualifying projects in a municipality's extraterritorial jurisdiction may be exempt when covered by a developer agreement2.

Who is the Brazoria County building department, and how do you reach them?

Start with the Brazoria County Floodplain/Building Permit Office for an unincorporated parcel. The office is at 451 North Velasco Street, Suite 210, Angleton, TX 77515, and its phone number is 979-864-12958. Tell the office whether the project is a new house, duplex, manufactured home, relocated structure or addition, and ask which permit and development reviews apply. Before covered residential construction begins, the builder must notify the Floodplain Administrator; the builder must also arrange the required inspections with an authorized inspector and submit the final compliance notice after inspection3. We could not confirm a general county certificate-of-occupancy rule, an agricultural exemption or a blanket owner-builder exemption, so ask the Floodplain/Building Permit Office about those points for the specific project.

Does Brazoria County have zoning?

Brazoria County has no zoning ordinance and does not regulate land use in its unincorporated areas4. At the county zoning level, that means no minimum dwelling size, minimum lot size, setbacks, lot-coverage limit or building-height limit, and no use restriction on accessory dwellings, RVs, tiny homes, manufactured homes or temporary camping6. No zoning does not erase other county controls: Brazoria County regulates subdivision of land within its jurisdiction, including small subdivisions and tract reconfiguration, and final plats require the applicable checklist materials9. Building-code, septic, drainage, floodplain and deed restrictions can also affect a project. These answers do not govern land inside a municipality, and we could not confirm every municipality's local zoning rules.

How do septic permits work in Brazoria County?

The Brazoria County Environmental Health Department reviews on-site sewage facility documents, issues permits and performs inspections10. A permit and approved plan are generally required before constructing, installing, altering, extending or repairing a septic system11. Texas has a narrow exemption for one single-family dwelling on at least 10 acres when every listed condition is met, including a licensed site evaluation, at least 100 feet from every part of the system to the property line, no nuisance or groundwater pollution, and disposal of effluent on the tract11. Only about 6 percent of Brazoria County soils avoid severe limitations for a conventional drain field, so make the site evaluation an early purchase contingency rather than assuming a standard system will work12. Contact Environmental Health at 979-864-1600 or [email protected]13.

Can you live in an RV or tiny home on your land in Brazoria County?

Brazoria County's lack of zoning means the county does not impose an RV, tiny-home or temporary-camping land-use restriction on unincorporated property6. A tiny home that is a new or relocated structure over 200 square feet still needs the county building permit, and manufactured homes require one as well1. A site-built tiny house may also fall within the county's residential-code and inspection order when it is a new single-family house23. Full-time occupancy still needs a lawful sanitation solution: Environmental Health handles OSSF permits and inspections10. We could not confirm a general utility-connection mandate or which off-grid sanitation alternatives the county accepts, so take the exact structure and wastewater plan to the building and septic offices before moving onto the parcel.

Building a home in Brazoria County: the steps, in order

  1. Confirm that the parcel is unincorporated and whether a proposed lot split, combination or reconfiguration needs county subdivision review9.
  2. Get a septic site evaluation and apply through the Brazoria County Environmental Health Department when an OSSF permit is required1011.
  3. Ask the Groundwater Conservation District about the permit pathway before drilling a regulated private well7.
  4. Meet with county development staff when drainage, fill or related engineering review applies; obtain a Letter of No Objection before applying for the Fill & Grade permit to begin dirt work14.
  5. Apply through the Floodplain/Building Permit Office when the structure meets the county permit threshold1.
  6. Arrange the applicable foundation, framing-and-systems, and final inspections for a covered new house or duplex3.
  7. For state-highway access, submit the required driveway application to TxDOT and wait for the executed permit before construction15.

What to check before you buy land in Brazoria County

Check septic feasibility first: only about 6 percent of the county's soils avoid severe limitations for a conventional drain field12. If the parcel needs a well, regulated wells require a Brazoria County Groundwater Conservation District permit, and the ordinary permit process is listed as 60 days; a temporary-permit route may allow drilling while final approval awaits a public hearing7. Ask whether proposed drainage, fill or dirt work requires county review, because applicable development submittals may need civil drainage plans, approvals and a Letter of No Objection before a Fill & Grade permit14. Verify that the legal tract matches the seller's description because Brazoria County regulates subdivision and tract reconfiguration within its jurisdiction9. For state-highway access, obtain TxDOT's executed driveway permit before construction15. Typical property tax is about 1.7 percent of value, with a median annual bill near $4,8311617.

Watch-outs

  • Covered new houses, duplexes and major additions must meet the county's residential-code order and inspection requirements; do not treat the building permit as floodplain paperwork alone23.
  • No county zoning does not mean no rules inside any city or town in Brazoria County; confirm your parcel is unincorporated before assuming these answers apply4.
  • We could not confirm a blanket owner-builder exemption; ask the Floodplain/Building Permit Office what the project must file18.

    • Emergency repairs listed by TCEQ do not require a permit but must be reported in writing to the permitting authority within 72 hours after repairs begin.
    • Grandfathered systems may also be exempt if the stated conditions are met.

    minimum tract size for 10-acre exemption: >= 10 acres (single-family dwelling and all other TCEQ conditions must be met) · minimum OSSF distance from property line for 10-acre exemption: >= 100 feet (all parts of the OSSF) · emergency repair reporting deadline: <= 72 hours (after repairs have begun; written report to permitting authority)

    “A permit is required to construct, install, alter, extend, or repair an OSSF. [...] An OSSF may be exempt from permitting if it complies with all other requirements, including planning, construction, and installation standards of 30 TAC 285 AND meets the “10 acre rule”:”
  • Septic inspectionLimited

    OSSF installation and, where applicable, maintenance inspections in Texas
