Compare Counties, Then Verify Parcels
Side-by-side scores can narrow your search, but parcel feasibility still depends on zoning, access, water, septic, covenants, permits, and current county review.

Quick answers
Which County Looks Better?
Saguache County leads on Freedom Score
Saguache County has the stronger overall Freedom Score, making it the better broad discovery candidate before parcel-level review.
Saguache County leads on tiny home signal
Saguache County has the stronger tiny home discovery score. Still verify whether the structure is treated as a dwelling, modular/manufactured home, ADU, or RV-like unit.
Costilla County and Saguache County are close on RV living signal
RV living looks similar at the county level. The deciding factor will usually be duration limits, sanitation, water, septic, campground rules, and parcel zoning.
Saguache County leads on off-grid signal
Saguache County has the stronger off-grid discovery score, helped by the county-level rule and rural-fit signals in the dataset.
Costilla County has the stronger land affordability score
Costilla County has the lower county-level price-per-acre snapshot at $4,203. Treat this as a market signal, not a parcel appraisal.
Best For
- Cheap land research
- Off-grid project research
- Permit-savvy rural buyers
- Solar-oriented land search
Pros
- Official planning resources are available online
- County requires land use permits and provides permit checklists
- Temporary RV during construction materials are listed
- Strong solar and rural land appeal
Cons
- County tells buyers to review the Land Use Code before purchase or land changes
- RV occupancy appears temporary/construction-linked unless separately approved
- Permanent container housing is not clearly confirmed
- Address, road access, OWTS, inspections, and building-code requirements can control feasibility
Red Flags
- Review the Land Use Code before purchase
- Do not treat temporary RV construction permits as permanent RV living
- Do not assume permanent container homes are allowed
- Confirm OWTS, address, access, utilities, wind load, snow load, and inspection requirements
RV Living
Costilla County lists a Temporary RV Occupancy During Home Construction permit and a Mobile Home Park and RV Park checklist. Score this as permit-based temporary/construction RV use, not confirmed full-time RV living on raw land.
Off Grid
Off-grid projects are plausible but compliance-heavy. The county permit list highlights OWTS, physical addressing, road access, utility, site plan, inspection, floodplain, and building-code requirements that can determine whether rural land is actually occupiable.
Water and Septic
Verify well, cistern, hauled water, and soil evaluation requirements with county and state water authorities before purchase. A physical address is not issued to vacant land according to the county planning page.
Planning resources include OWTS permit and occupancy inspection materials. Septic/OWTS should be treated as a core prerequisite for occupancy research.
Best For
- Tiny home research
- Off-grid living research
- Alternative building methods
- Rural land buyers comfortable with limited services
Pros
- County says it is not zoned but does require building permits
- Alternative building methods including shipping containers are allowed with correct permitting
- Clear county FAQ on camping, OWTS, wells, access, utilities, and building constraints
- Strong solar and low-density rural context
Cons
- Permanent RV, camper, or tent residence is explicitly not allowed
- Temporary RV permits require approved OWTS and active construction permit
- County services, roads, internet, school buses, and utilities may be limited
- Access is buyer-beware and not guaranteed
Red Flags
- Do not market Saguache as permanent RV-living friendly
- Confirm OWTS before occupancy assumptions
- Verify well type and water rights based on parcel acreage
- Check legal access, private road maintenance, covenants, HOA, POA, and incorporated-area rules
RV Living
Saguache County says temporary RV permits may be issued after county-approved OWTS installation and with an active construction permit, valid for the life of the construction permit. The county explicitly says an RV, camper, or tent may not be used as a permanent residence, so RV living should be scored as temporary/construction-only rather than full-time RV-on-land freedom.
Off Grid
Saguache is still one of the strongest off-grid research counties, but the county warns that services may be limited, electrical grid connection can be expensive or unavailable, road maintenance is not guaranteed, all rural residential properties require OWTS, and water rights/wells depend heavily on parcel size and state rules.
Water and Septic
The county FAQ notes rural properties often lack central water/sewer; wells depend on acreage and water rules. Parcels under 35 acres may be limited to in-house well use, and water rights should be verified with Colorado Division of Water Resources.
Saguache requires a county-approved OWTS to live or stay on property. The county does not allow composting/incinerating toilets unless an approved OWTS is installed first.
