Dawson County has no county building permit or building code for unincorporated land. TCEQ lists the County as its authorized agent for septic (on-site sewage) permits everywhere in the county, Lamesa included, with the work handled through the South Plains Public Health District (806-559-8895). Building permits come from the City of Lamesa, whose Inspections Department issues building, electrical, plumbing and mechanical permits inside the city and takes applications online through iWorQ. Ackerly and O’Donnell, which straddle the county line, and tiny Los Ybanez publish nothing on permits.

Lamesa permit hours and septic systems

Lamesa’s inspection staff are in the office from 8 to 9 a.m. and 1 to 2 p.m. on weekdays, and permits are issued only in those two windows; the rest of the day the inspectors are in the field and can be reached by cell phone or email.

Septic systems anywhere in Dawson County, inside Lamesa as well as on rural land, are permitted by the County as TCEQ’s authorized agent. The South Plains Public Health District posts the application and authorization to construct, which asks for the installer, site evaluator and (where needed) designer, a soil test hole at least 24 inches deeper than the drain field, and a scaled drawing of the system; a lot under 1 acre needs a variance.

Inspections in Lamesa

Give the Inspections Department 24 to 48 hours’ notice to schedule an inspection, by calling 806-872-2124 ext. 329 or emailing cityinspector@ci.lamesa.tx.us; permit holders can also find their permit on the iWorQ portal and request the inspection there. Certificates of Occupancy are among the permits the City issues. On unincorporated land the County publishes no building inspection service.

Texas building code

Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
