Inspections

How to Schedule

• CID District Office (505) 476-4500 (phone)

Time windows

Cuchillo's remote location (approximately 35 miles from Truth or Consequences on Highway 52, in mountainous terrain approaching the Black Range and the western edge of the Gila National Forest) means inspector travel time from the nearest CID district office is significant. Request inspection scheduling with additional lead time (2 to 3 weeks or more). Confirm with CID at (505) 476-4500.

Typical inspection sequence: Typical sequence for residential construction: (1) Foundation/footing inspection (prior to concrete pour); (2) Underground utility rough-in (electrical conduit, plumbing waste/supply); (3) Framing inspection (after framing complete, before insulation or drywall); (4) Rough-in inspection (electrical, plumbing, mechanical rough-in); (5) Insulation inspection (before drywall); (6) Final inspection (all work complete; Certificate of Occupancy issued upon passing). Trade permit inspections (electrical, plumbing, mechanical) may be scheduled separately.

Cuchillo is one of the most remote communities in Sierra County. Inspection logistics and response times for CID are a practical concern that clients should factor into project scheduling.
