Titus County, TX Building Permits, Zoning & Septic Rules

Unincorporated Titus County, Texas does not require a building permit for a single-family home, because Texas counties generally have no authority to require one outside cities¹. Titus County also has no zoning ordinance, so it sets no minimum lot size, setback or building-use rule on ordinary unincorporated land². What the county does regulate directly is septic and subdivision: an on-site sewage facility (OSSF) permit runs through the county's own Environmental Inspection Service, and any new subdivision needs Commissioners' Court plat approval³⁴. A driveway onto a state highway has its own separate TxDOT permit⁵.

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

Titus County does not require a building permit for a single-family home in unincorporated areas¹. Texas law generally withholds building-permit and inspection authority from counties for residential construction outside cities, and Titus County's environmental office handles OSSF permitting and inspection, not general building permits¹. Texas Local Government Code Chapter 233, Subchapter F lets some counties require inspections of new residential construction, but only if the commissioners court has adopted a resolution or order applying it, and no record of Titus County doing so was found¹⁰. Statewide, industrialized housing, modules and modular components must meet specific mandatory codes effective July 2024, regardless of county permit rules¹¹. If you are subdividing land rather than building on an existing tract, Titus County's platting rules apply instead, and are described below⁴.

Who handles septic and subdivision approval in Titus County, and how do you reach them?

Titus County has no building or zoning department, so there is no building-permit office to contact¹. Septic (OSSF) permits go through the county's own Environmental Inspection Service, a TCEQ-authorized agent under Titus County's locally adopted OSSF orders³. Subdividing land outside a municipality requires plat approval from the Titus County Commissioners' Court; the Titus County Judge's Office is the county's central contact for that process and for anything not covered by a specific department¹². Approved plats, tax certificates and the filing fee are handled through the Titus County Clerk's Office¹³. A driveway onto a state highway needs a TxDOT permit instead of a county permit⁵.

Does Titus County have zoning?

Titus County has no zoning authority under Texas law and no zoning ordinance². Texas gives counties general zoning power only in narrow, specifically named situations — Padre Island in Cameron or Willacy County, the Amistad Recreation Area in Val Verde County, and a handful of other named areas — and Titus County is not one of them¹⁴. Because Titus County has no zoning, there is no county-set minimum lot size, minimum dwelling size, setback, lot-coverage limit or building-height limit for ordinary unincorporated land². The one numeric lot-size rule that does apply is narrower: a subdivision using individual OSSFs for sewage disposal must give each lot at least 1 acre of usable property, regardless of zoning⁷. For the same no-zoning reason, an accessory dwelling unit, a manufactured home, an RV, a tiny home, or temporary camping on your own unincorporated Titus County land is not restricted by any county zoning rule².

How do septic permits and subdivision approval work in Titus County?

Texas requires a permit to construct, install, alter, extend or repair an on-site sewage facility (OSSF) anywhere in the state¹⁵. In Titus County, that permit is issued locally by the county's own Environmental Inspection Service rather than by a TCEQ regional office³. A property on at least 10 acres may qualify for Texas's '10-acre rule' exemption from OSSF permitting if a licensed site evaluator confirms the system will sit at least 100 feet from every property line, serves a single dwelling that is the only one on the tract, and creates no nuisance or groundwater pollution¹⁵. If you are creating a new subdivision rather than building on an existing lot, Titus County's Commissioners' Court must approve the plat, and the filing fee is $121⁴. For a subdivision served by OSSFs, each lot needs at least 1 acre of usable property excluding easements and rights-of-way, and planning materials — including a 100-year floodplain map and a comprehensive drainage plan — must be approved before individual OSSF permits can be issued¹⁶⁷. Subdivision roads must have a graded bed at least 30 feet wide within a right-of-way of at least 60 feet, with culverts at least 12 inches in diameter and 30 feet long, and the county may require a road-construction bond of at least $189 per linear foot⁹⁴.

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

Titus County has no zoning ordinance, so RV occupancy, tiny-home occupancy and manufactured-home occupancy on your own unincorporated land are not restricted by any county land-use rule². Temporary camping on your own unincorporated property is likewise unrestricted by county rule for the same reason². This is a real answer grounded in Texas's narrow county-zoning law, not just an absence of research: Titus County simply lacks the zoning authority that would let it regulate these uses¹⁴. It does not override septic or subdivision rules — an RV, tiny home or manufactured home used as a residence still needs a compliant OSSF, and if you are creating a new lot for it, county subdivision and minimum-lot-size rules apply⁷.

Building on land in Titus County: the steps, in order

Confirm your parcel is in unincorporated Titus County; the county has no zoning or building-permit requirement there¹.
If you are creating a new lot rather than building on an existing one, get your plat approved by the Titus County Commissioners' Court before doing anything else; the filing fee is $121⁴.
For an OSSF-served subdivision, budget for at least 1 acre of usable property per lot and submit planning materials, including a 100-year floodplain map and drainage plan, for approval within 45 days¹⁶⁷.
Apply for an OSSF (septic) permit through Titus County's Environmental Inspection Service before you build³.
If your land is on at least 10 acres and meets Texas's other conditions, ask whether the 10-acre OSSF exemption applies instead¹⁵.
If your driveway will connect to a state highway, submit TxDOT Form 1058 and wait for a fully executed permit before any work begins on the right-of-way⁸.
For anything not covered above — plat questions, general permitting — contact the Titus County Judge's Office or the County Clerk's Office¹²¹³.

What to check before you buy land in Titus County, Texas

Titus County sits about 65 miles from the nearest metro area, with a population density around 77.2 people per square mile — closer to town than a truly remote county¹⁷¹⁸. About 40.1% of the county is wooded, and 92.6% of the land sits at 15% slope or less¹⁹²⁰. Soils are a serious constraint for septic: only 5.3% have no severe limits for a conventional drain field, so a site evaluation and likely an alternative or engineered system should be part of any budget²¹. Annual precipitation runs about 47.9 inches, and the county has spent roughly 14.3% of recent years in severe drought²²²³. Farmland has recently valued around $3,394 an acre, well below the typical home value of about $227,637²⁴²⁵. A typical home insurance premium runs about $2,096 a year, the effective property tax rate is about 1.2%, and the median annual property tax bill is near $1,897²⁶²⁷²⁸. Before closing, confirm septic suitability with the Environmental Inspection Service, check whether the parcel is part of an unrecorded or informal subdivision that may need retroactive plat approval, and ask the County Judge's Office about anything not posted online³¹².

Watch-outs

Titus County's 1-acre OSSF minimum lot size and subdivision road standards apply to new subdivisions platted after the rule's effective date; an existing platted lot from before then may not need to meet the current minimum⁷.
Whether Titus County has adopted Texas's optional Chapter 233 residential inspection program was not confirmed on any official page found; if it has, inspections could apply even though no general building permit is required¹⁰.
Certificates of occupancy, owner-builder exemptions, short-term rental rules and well permitting for Titus County were not confirmed on any official source found; ask the County Judge's Office directly¹².
Only 5.3% of Titus County's soils have no severe limits for a conventional septic drain field; get a site evaluation before you assume a standard system will work on a specific parcel²¹.
