Side-by-side scores can narrow your search, but parcel feasibility still depends on zoning, access, water, septic, covenants, permits, and current county review.
How to use this comparison
Compare Counties, Then Verify The Actual Parcel
This page helps you compare county-level signals side by side. The better county on paper can still lose once parcel zoning, private restrictions, access, water, septic, and build costs are checked.
Check source support separately
Idaho County is verified ✓; Lemhi County is verified ✓. County-level profile has stronger official source coverage, but parcel-level approval is still not confirmed. County-level profile has stronger official source coverage, but parcel-level approval is still not confirmed.
Move from county to parcel
Before acting, confirm zoning district, allowed use, occupancy, water, septic, access, utilities, title, covenants, and permit path for the exact property.

Next research moves
Before You Pick Either County
A comparison page should narrow the search, not end it. Use this checklist to turn the county match into a parcel-specific source checklist and due-diligence plan.
Confirm jurisdiction
Check whether the parcel is handled by unincorporated county rules, a city, a subdivision, a special district, or another authority before relying on either Idaho County or Lemhi County score.
Verify intended use
Describe the exact plan: tiny home, RV stay, manufactured home, container build, cabin, ADU, garden, livestock, or off-grid system.
Check land basics
Confirm legal access, road maintenance, slope, floodplain, wildfire exposure, title issues, easements, covenants, and whether utilities are nearby.
Price the hard systems
Water, septic, driveway, power, winter access, grading, and permitting costs can change the better county once you move from county-level research to a real parcel.
Quick answers
Which County Looks Better?
Idaho County and Lemhi County are close on Freedom Score
Idaho County and Lemhi County are close overall, so the better choice depends on the specific parcel, use case, and local code path.
Idaho County and Lemhi County are close on tiny home signal
Both counties have similar tiny home discovery scores. Compare zoning district, dwelling classification, utilities, and building-code requirements before choosing.
Idaho County and Lemhi 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.
Idaho County and Lemhi County are close on off-grid signal
Both counties are close for off-grid research. Solar, access, winter conditions, water rights, well feasibility, and septic will likely decide the better parcel.
Idaho County has the stronger supported land affordability score
Idaho County has the lower county-level price-per-acre snapshot at $5,925. Treat this as a market signal, not a parcel appraisal.
Best For
- very large rural land searches
- Idaho County off-grid screening
- multi-use unincorporated land due diligence
Pros
- Official Building/Living overview says unincorporated land is multi-use with subdivision and mobile/manufactured-home exceptions
- the same overview says outside city limits or city areas of impact the building requirements are state requirements
- Very low density and high public-land acreage make Idaho County a priority research county
Cons
- The overview is promising but not tiny-home-specific or RV-occupancy-specific
- city limits, areas of impact, subdivisions, mobile/manufactured-home rules, state requirements, water, septic, access, wildfire, and road maintenance can still materially affect feasibility
Red Flags
- Verify city or area-of-impact status, subdivision status, state building path, mobile/manufactured-home rules, wastewater, water rights or well path, access, covenants, and whether RV or tiny-home occupancy is permitted before purchase
RV Living
RV or camper occupancy should be confirmed directly with Idaho County because the Building/Living overview does not establish a blanket full-time RV living path on private land.
Off Grid
Off-grid projects may be attractive because of low density, multi-use unincorporated land language, and very large public-land context, but buyers should verify state requirements, septic, well or water rights, access, wildfire response, road maintenance, addressing, subdivisions, city or area-of-impact boundaries, and covenants before relying on acreage.
Water and Septic
Water supply is parcel-specific; the county overview points buyers toward well drillers, Idaho Department of Water Resources, and water-rights review before purchase.
Sewer and energizing permits should be checked with North Central Public Health, and septic feasibility should be confirmed with the applicable health authority before purchase.
Best For
- Salmon area rural land research
- mountain county off-grid screening
- buyers who need visible building resources
Pros
- Official building page identifies a county/city building department and land-use assistance role
- county FAQ points buyers to septic and well feasibility checks
- Lemhi has very low density and large public-land context for mountain off-grid screening
Cons
- Formal building permit, access, septic, well, snow-load, and city-jurisdiction review can limit informal use
- raw land addressing and access may create hurdles
- mountain parcels may have snow, wildfire, and road-maintenance constraints
Red Flags
- Verify building permit path, site plan, setbacks, access permit, septic, well, snow load, covenants, city boundaries, and whether a proposed tiny home or RV is legally occupiable before purchase
RV Living
RV or camper occupancy should be confirmed directly with Lemhi County because the building resources do not establish blanket long-term RV living rights.
Off Grid
Off-grid projects should verify access permits, 911 addressing, septic, well requirements, setbacks, snow load, road access, county/city building review, wildfire exposure, and road maintenance before relying on rural acreage.
Water and Septic
Water availability should be checked with Idaho Department of Water Resources and local well feasibility resources before purchase.
Septic feasibility should be confirmed with Eastern Idaho Public Health before purchase because the county FAQ identifies septic review as part of buildability.
