How to Schedule

• (575) 524-6320 - CID Southwest Regional Office (phone)

Scheduling deadline

Advance scheduling of 48 to 72 hours minimum is typical; greater lead time may be needed given travel distances from Las Cruces.

Typical inspection sequence: Typical sequence: 1) Foundation/footing (before concrete pour), 2) Underground plumbing and electrical (before backfill), 3) Rough framing (before insulation or drywall), 4) Rough plumbing, mechanical, and electrical (before concealment), 5) Insulation (before drywall), 6) Drywall/lath (if applicable), 7) Final building inspection (all work complete, ready for occupancy). Trade-specific final inspections (electrical, plumbing, mechanical) may be conducted by separate CID trade inspectors or combined with building inspector visit.

Given that Hidalgo County is approximately 120 miles from the Las Cruces regional office, inspection scheduling requires advance coordination.
