Do you need a building permit in Lee County, Texas?
Unincorporated Lee County, Texas requires a development permit for any individual structure larger than 100 square feet1. The county page says development applications cover residential and commercial work, including a new or modified home or business and moving a home onto property6. Lee County Development Services charges $50 for a residential home application, $25 for a residential accessory structure, $10 for a residential addition and $100 for a commercial application6. Failing to secure the application carries a $250 penalty, while the listed floodplain penalty is $1,000610. A new residence or business project also needs a 9-1-1 address before any permit application6.
Who is the Lee County building department, and how do you reach them?
Lee County Development Services, also called the Code Enforcement office, handles building permits, 9-1-1 addressing, subdivisions and floodplain permits for the whole unincorporated county6. Reach the office at 979-212-8070 or [email protected]6. Its temporary physical location is the Lee County Annex behind the Tax Office at 898 East Richmond, Ste 203, in Giddings, though mail goes to 200 South Main, Ste 203, Giddings, TX 789426.
Does Lee County have zoning?
Texas law gives counties zoning power only in limited circumstances, and the county legal census found no Lee County zoning ordinance for unincorporated land211. Unincorporated Lee County therefore has no zoning-based minimum dwelling size, setback, building-height limit, lot-coverage rule or use district7. That does not erase other county rules: subdivisions using on-site sewage facilities have a minimum lot size of 1 acre, and subdivision plats require county approval3. Municipal rules can differ inside city limits, and the available research does not inventory zoning in every Lee County municipality.
How do septic permits work in Lee County?
Lee County is the authorized agent for on-site sewage facilities, and the county says all septic systems must be permitted45. Lee County lists a $425 residential septic fee and a $500 commercial septic fee5. Texas generally requires a permit before constructing, installing, altering, extending or repairing an OSSF12. A qualifying single-family system on at least 10 acres may be exempt if all parts sit at least 100 feet from the property line and the other state conditions are met, but Lee County may impose stricter local requirements12. Only about 19% of Lee County soils lack severe limitations for a conventional drain field, so obtain a site evaluation before assuming a basic system will work13.
Can you live in an RV or tiny home on your land in Lee County?
Unincorporated Lee County has no zoning-based restriction on RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping on your own parcel7. A permanent tiny-home structure larger than 100 square feet still requires the county development permit1. A new residence needs a 9-1-1 address before permit applications, and any septic system must go through the county permitting process65. The county page also publishes separate manufactured-home-community and recreational-vehicle-development materials, so ask Development Services about those rules before creating rental sites or a multi-unit development6.
Building a home in Lee County: the steps, in order
- Apply for a 9-1-1 address; Lee County requires one for a new residence before permit applications6.
- Submit the home development application to Lee County Development Services; the listed residential-home application fee is $506.
- Obtain a private driveway permit for county-road access; the listed fee is $25, with a $15-per-foot culvert-installation charge where applicable9. A state-highway driveway instead requires TxDOT Form 105814.
- Apply to Lee County for the septic permit and complete the site evaluation; the residential permit fee is $425513.
- Determine whether the site is in a floodplain and complete the floodplain process; county floodplain work is subject to compliance inspections, and an elevation certificate may be due within 10 business days after foundation completion when required15.
What to check before you buy land in Lee County
About 100% of Lee County land has a slope of 15% or less, but buyers should still inspect drainage and the specific building pad16. About 20% of the county is wooded, while only around 19% of soils lack severe limitations for a conventional septic drain field1713. Lee County has about 29 people per square mile, and the nearest city of 100,000 or more is about 41 miles from the county center1819. The effective property-tax rate is about 1%, and the median annual property-tax bill is about $2,3992021. Review flood status, legal road access, deed restrictions, water availability and any subdivision plat before closing; county zoning does not answer those parcel-specific questions73.
Watch-outs
- Lee County's own permitting page does not state an owner-builder exemption one way or the other; confirm directly with Development Services before assuming you can act as your own contractor8.
- Lee County's development-permit materials do not identify a general building code or certificate-of-occupancy rule outside the documented floodplain process; ask Development Services what inspections and closeout documents apply to the parcel115.
