Do you need a building permit in Howard County, Texas?
No. Unincorporated Howard County, Texas has no county building-permit department, and Texas counties generally lack the authority to require prior approval for ordinary residential construction1. A conventional site-built house on land outside a city therefore does not need a Howard County building permit1. Industrialized or modular housing follows a separate state process: an owner installing a home for personal use may use a residential installation permit and owner-builder exemption69. Land inside the City of Big Spring is different because city permits and technical codes apply there10.
Who handles permits and inspections in Howard County?
There is no county building department to call for a home-construction permit, because Howard County does not operate one1. The Howard County OSSF Office handles on-site sewage facility permits and posts the septic permit application for unincorporated Howard County311. Contact the Howard County Road Administrator for a new or modified driveway onto a county road7. Subdivision driveways that cross drainage courses need permanent drainage structures, with the Commissioners Court setting their dimensions and type during plat review12. An industrialized or modular home needing a state residential installation permit goes through the Texas Department of Licensing and Regulation rather than a county building office13.
Does Howard County have zoning?
Howard County has no countywide zoning ordinance2. In unincorporated Howard County, no county zoning rule sets minimum dwelling size, minimum lot size, lot coverage, building height, accessory-dwelling use, tiny-home occupancy or temporary camping5. A platted subdivision may still carry a building or setback line, and no structure may be placed between that line and the street right of way14. A manufactured home rental community also follows separate development rules: before construction, its infrastructure plan must receive Commissioners Court approval and address drainage, water, waste, sanitation, surveying and roads15. Inside the City of Big Spring, zoning is different: the city administers its own Zoning Ordinance and zoning maps, and allowed uses vary by zoning district16. Dividing unincorporated land into lots is also regulated: the Howard County Commissioners Court must approve a plat before a division for residential, commercial or other development proceeds17. Land divided for agricultural, farm, ranch, wildlife-management or timber-production use outside city limits can qualify for an exemption, but septic, floodplain and road requirements still apply, and platting applies if the use ends18. Check the recorded plat and development type before choosing a homesite1415.
How do septic permits work in Howard County?
Howard County regulates on-site sewage facilities (OSSF, commonly called septic) in the unincorporated area, and the county's OSSF Office posts the permit application311. Texas generally requires a permit and approved plan before an OSSF is constructed, altered, extended or repaired4. A single-family home on at least 10 acres may qualify for an exemption only if every state condition is met, including professional site evaluation, 100-foot property-line clearance for the system, on-site effluent disposal and no other dwelling on the tract4. The permitting authority or its representative inspects installation, but the available rule does not establish periodic inspection for every system19. On subdivided land, a lot using septic must have a permitted OSSF or be legally serviceable under state standards before certain utility connections can proceed20. Only about half of Howard County's soils avoid severe limits for a conventional drain field, so arrange a site evaluation before buying21.
Can you live in an RV or tiny home on your land in Howard County?
Unincorporated Howard County has no zoning rule barring tiny-home occupancy or temporary camping on your own land, and no county zoning rule sets a minimum home size5. An RV or manufactured home placed in a manufactured home rental community is different: a community with rented or leased residential spaces must obtain Commissioners Court approval of an infrastructure plan before construction2215. That plan must address drainage, water, solid waste, sewer or OSSF facilities, surveying and roads15. OSSF is allowed as an alternative to sewer service for an unincorporated subdivision only when the lot has a permitted system or the subdivision can legally support systems meeting state standards23.
Building a home in Howard County: the steps, in order
- Confirm the parcel is in unincorporated Howard County rather than Big Spring, where city permits and codes apply10.
- Check the recorded plat for a building line and determine whether subdivision or manufactured home rental community review applies1415.
- Arrange the OSSF site evaluation and ask the Howard County OSSF Office whether the system needs a permit or qualifies for the state exemption114.
- For an industrialized or modular home built for your own use, apply for the state residential installation permit and owner-builder certification6.
- Apply to the Road Administrator for county-road access, including any drainage structure required where a subdivision driveway crosses a drainage course712. A state-highway driveway instead requires TxDOT Form 1058 through the local district office8.
- For subdivided land, confirm the required plat approval and water, sewer or OSSF infrastructure before requesting utility service24.
What to check before you buy land in Howard County
Only about half of Howard County's soils avoid severe limits for a conventional drain field, so test the homesite rather than assuming it will support the planned system21. Nearly all of the county, 98.5%, has a slope of 15% or less25. Howard County averages 18.5 inches of precipitation a year and experiences severe drought in roughly 32% of years, making the water source worth verifying before purchase2627. Confirm legal access and road maintenance; county-road driveways go through the Road Administrator, while state-highway access follows TxDOT's permit process728. If any part of land intended for residential housing lies in a floodplain, the Commissioners Court cannot approve the plat unless the subdivision meets National Flood Insurance Program minimums and the county's Flood Damage Prevention Order29. Subdivision and manufactured home rental community review carries published fees paid before county review, in addition to filing or recording charges30. The effective property-tax rate is 1.1%, the median annual bill is about $1,642, and typical annual home insurance is about $2,355313233.
Watch-outs
- We could not confirm a Howard County well-permit process or which groundwater conservation district covers the county from official sources; ask the OSSF Office or County Judge's office who administers well permits before you drill11.
- We could not confirm from official sources whether Howard County requires a certificate of occupancy for a new home; ask the OSSF Office before you finish construction11.
