Costilla County Land Zoning Explained: What You Can (and Can’t) Do with Your Property

Understanding a property’s zoning in Costilla County, Colorado

Understanding a property’s zoning in Costilla County, Colorado, is vital for any land buyer. Zoning dictates how land can be used, what can be built, and minimum acreage requirements, ensuring your vision aligns with county regulations.

Deciphering Costilla County’s Common Zoning Classifications

Costilla County primarily features Agricultural (A) and Estate Residential (ER) zones, each with distinct purposes.

Agricultural (A) Zone

The “A” (Agricultural) zone is established to preserve and protect rural areas where the conservation of agricultural resources and agricultural production is of major importance. It typically applies to larger parcels, protecting farming, ranching, and open space. 35-acre parcels are frequently found within this designation, influencing water rights and subdivision potential in Colorado. Allowable uses include farming, dairying, pasturage, horticulture, and animal husbandry. Accessory uses for packing, treating, or storing produce are permitted as secondary to normal agricultural activities. While a residence is permitted, specific minimum acreage (often 5-10 acres) is usually required for well and septic system compliance, ensuring adequate space and health standards.

Estate Residential (ER) Zone

The ER (Estate Residential) zone supports low-density residential development with a spacious, rural feel. It permits single-family homes, garages, workshops, and recreational activities. Crucially, all properties listed by Open Skies Land are within these Estate Residential zones, offering ideal potential for your dream home or cabin. This district is characterized by predominantly lots of less than 35 acres. ER zones also have minimum lot size requirements to accommodate compliant well and septic systems.

According to Costilla County’s Land Use Code, properties within the Estate Residential (ER) zone generally adhere to the following guidelines regarding property use:

  • Dwellings: Primarily permits single-family residences. Manufactured homes are typically allowed, often with specific requirements for installation and appearance. The Land Use Code indicates that Accessory Dwellings are also permitted in ER zones.
  • Accessory Structures: Common accessory structures like garages, workshops, sheds, and storage buildings are permitted. These may be subject to size and setback limitations.
  • Minimum Dwelling Size: The Costilla County Land Use Code specifies a minimum size of 600 square feet for all single-family dwellings. Buyers should also ensure properties meet all health department regulations for septic and well.
  • Animals & Livestock: Household pets are permitted. Keeping a limited number of common farm animals (e.g., horses, chickens, goats) for personal use is often allowed on larger ER parcels, though specific limits may apply based on acreage and animal type. Commercial animal operations are typically prohibited.
  • Agricultural Activities: Small-scale gardening and personal cultivation for non-commercial purposes are generally allowed. Commercial farming or ranching operations are generally not permitted.
  • Commercial Activities: Commercial or industrial uses are generally not allowed. Home-based businesses that do not generate significant traffic, external signage, or alter the residential character of the property may be permitted under specific conditions.
  • Recreational Vehicle (RV) & Camping Use: Temporary RV use for recreational purposes up to 14 days every three months or during the construction of a permanent dwelling is often permitted for limited durations. Long-term or commercial RV parks/campgrounds are typically prohibited.
  • Subdivision: While ER zones are for residential development, further subdivision of parcels may be restricted or require compliance with specific county subdivision regulations and minimum lot sizes.

While A and ER are predominant for individual land sales, Costilla County also has other zones like Business/Commercial (BC) for commercial, service, wholesale and office uses or Industrial (I) for industrial and service businesses, and Urban Residential (UR) for residential development at higher densities with central water and sewer services.
