Residential Land for Sale in San Luis, Colorado
12th St, San Luis, CO 81152
One of the biggest expenses when setting up an off-grid property can be the initial site work. This 5-acre parcel in Mount Blanca Valley Ranches already has an inspected septic system installed. It's in excellent condition and has never been used, giving you a useful head start on your plans. There's also a cleared area on the property and direct road access from 12th Street. Be sure to watch the narrated video walkthrough for a closer look at the land and its features.
The land has light shrubs, open meadow areas, and views of Mount Blanca and the surrounding hills. There's no mandatory HOA and no deadline to build, so you can take your time planning your next steps. If you decide to build a home or install an eligible manufactured home built in 1976 or later, county requirements include a minimum of 600 square feet and the necessary permits. Water can typically be supplied through a permitted well or cistern.
Costilla County also allows recreational camping for up to 14 days in any consecutive three-month period. Longer RV stays of up to 18 months may be allowed while actively building, provided the applicable septic, water, and county requirements are met.
For supplies and everyday needs, Blanca and San Luis are both about 23 minutes away, Fort Garland is roughly 27 minutes away, and Alamosa is around 42 minutes away. Smith Reservoir State Wildlife Area is about 20 minutes away for fishing and wildlife viewing, while Great Sand Dunes National Park and Preserve is approximately 50 minutes away.
If you're looking for Colorado land with an existing septic system, road access, and a head start on your off-grid plans, reach out to learn more about the property and available financing options.
