Where Mount Blanca Valley Ranches is

The Costilla County part of the subdivision lies in the west part of the county, south of US 160, near Mount Blanca Estates. County roads such as County Road 12 and the lettered roads X, Y and Z cross the area. The land is flat sagebrush and grass at about 7,650 to 7,850 feet, with Mount Blanca to the northeast.

County GIS shows Units 2, 3, 4 and 9 in Costilla County. Some lots sold under the same name lie in Alamosa County instead, so check which county sends your tax bill. On a Costilla County bill, the legal description starts with M.B.V.R., then the unit, block and lot. If your lot is in Alamosa County, contact us anyway.

Lot sizes and what lots sell for

In the county parcel map, about 85 percent of the Costilla County lots measure close to 5 acres. A few owners hold two or more lots side by side, and about 20 tracts are larger than 10 acres.

We did not find a public source that tracks sale prices for Mount Blanca Valley Ranches alone, so these are county figures. Recent market data for Costilla County shows a median sale of $9,000 for lots of 5 to 10 acres, across 219 sales, and $9,000 for lots of 2 to 5 acres. The county median land sale was $11,000, and land took about 152 days to sell on average. A lot near a county road, or with a well permit on file, tends to be easier to sell.

Water and wells

No water system serves these lots. A home needs a private well or a buried cistern of at least 500 gallons with hauled water. The Colorado Division of Water Resources (DWR) issues well permits. On a lot under 35 acres, a small exempt well is usually limited to household use inside one home, and wells in subdivisions approved on or after June 1, 1972 get extra review. The Rio Grande groundwater rules exempt only small wells that meet that state law.

We did not find an augmentation plan for Mount Blanca Valley Ranches in state records. Look up your lot in DWR's Well Permit Search. If a permit already exists, the buyer can move it into their name with DWR's change-of-owner form.

Roads, access and power

Lots front dirt roads laid out on the plat. Some see little traffic and can be rough or muddy after storms. Costilla County requires a Road Access permit before you build a driveway on a vacant lot unless one was issued before; the form lists a $200 fee.

The San Luis Valley Rural Electric Cooperative provides power in the county. Most vacant lots here have no line nearby, so owners use solar or request a quote for a line extension. If your lot has no clear access, we still buy it.

Camping, RVs and building rules

We did not find an active owners' association for Mount Blanca Valley Ranches. Recorded deed restrictions may still exist, and the county does not enforce them.

Costilla County rules apply to every lot. Staying in an RV or tent on the same parcel for more than 14 days total in any three months needs a Long-term Camping Permit. An RV may not serve as a full-time home or as storage. To live in an RV while you build, the county asks for a construction permit, a well permit or cistern, and an approved septic system that the RV hooks into.

A home needs a septic (OWTS) permit first; the new-permit fee is listed at $500. The home must be at least 600 square feet with a kitchen and a bathroom, one home per parcel. Manufactured homes must be 1976 or newer. The county does not enforce private covenants. Rules and fees change, so call Planning and Zoning at 719-937-7668 before you count on them.

Property taxes

The Costilla County Treasurer in San Luis sends the tax bill for Mount Blanca Valley Ranches lots. Pay half by the last day of February and half by June 15, or the full year by April 30. Late taxes add 1 percent interest per month. Check your balance on the Treasurer's page or call (719) 937-7672.

Unpaid taxes lead to a tax lien sale. The county holds it online each fall, and the 2026 sale starts November 3. The buyer of the lien does not own your lot. You can still redeem by paying the taxes, interest and costs until a treasurer's deed is issued. Read more on our Costilla County back taxes page.
