Domestic wells and the Rio Grande adjudication
A property that is not connected to a municipal system generally needs a domestic well permit from the Office of the State Engineer, issued under NMSA 72-12-1.1 and the rules in 19.27.5 NMAC, which set limits on how much a household well may divert. Separately, the Lower Rio Grande adjudication, a case in the Third Judicial District Court in Doña Ana County, is determining the priority, amount and other elements of each water right in the Lower Rio Grande basin, including lands in the Elephant Butte Irrigation District.
Do not assume a lot can get a new well or carry an irrigation right. Ask the State Engineer for the well permit file and the water right record, confirm the well's depth, use and annual limit, and consider a New Mexico water attorney for any lot you plan to rely on for irrigation or more than one home.
Splitting land, access and records
New Mexico's Subdivision Act excludes some divisions, including the sale of a parcel of 35 acres or more within a twelve-month period when the land has been in agricultural use for three years, and a conveyance that creates no parcel smaller than 140 acres, so ask the county whether a parcel was legally created. Many rural parcels are on dirt roads, so confirm recorded legal access and county maintenance. Sierra County regulates septic systems and building separately from the State Engineer, so ask the county. New Mexico is a non-disclosure state, so sale prices are not on public records.
