No official countywide general building department or general building-permit program for ordinary vertical construction in unincorporated Gaines County was publicly identified.

Application Process

  1. Confirm the parcel is in unincorporated Gaines County and not inside Seminole or Seagraves.
  2. Determine whether the project actually triggers one of the county's verified approval programs. No public county source established a countywide general building permit for ordinary vertical construction.
  3. If the project is a subdivision or manufactured home rental community in the unincorporated county, contact the County Judge's office and obtain the current county application and checklist. The county regulations recommend meeting with the commissioner and/or County Judge at least 14 days before submitting a plat application.
  4. Submit the completed plat or MHRC application, supporting documents, and fees to the County Judge or designee. County regulations state a complete plat application includes the application, proposed plat, supporting documents, and cashier's check or money order for fees.
  5. If the project involves an on-site sewage facility, return the OSSF application to South Plains Public Health District and do not begin septic construction until authorization is received. The county regulations say subdivision construction using OSSF must obtain authorization from the SPPHD designated representative before commencing or continuing construction in the subdivision.
  6. Schedule OSSF inspection through South Plains Public Health District using the contact numbers in the application packet.
  7. If a new structure is being built or moved onto a site in the unincorporated county, submit the 9-1-1 Rural Address Application before an address can be assigned.
  8. Complete any county subdivision review, SPPHD inspection, and final plat recording steps that apply before occupancy, utility setup, or lot conveyance.

Typical processing time: Subdivision plats: if incomplete, the county must notify the applicant of missing items not later than the 10th business day after receipt; the Commissioners Court must approve, approve with conditions, or disapprove a completed plat application not later than the 30th day after receipt, subject to a written extension of up to 30 days.
