Application Process
- Confirm the parcel is in unincorporated Crosby County and not inside Crosbyton, Lorenzo, or Ralls.
- Do not assume a county general building permit is required. Contact the County Judge's office first to confirm whether the project triggers any county-administered requirement such as subdivision, floodplain, road-access, or other local review.
- If the project will use an on-site sewage facility, confirm the applicable OSSF permitting path under TCEQ and Crosby County's authorized-agent role before installation.
- If the project is lender-driven or otherwise requires private third-party residential inspections in unincorporated territory, verify whether Texas HB 2833 related private-inspection rules affect the inspection path.
