Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesGarfield County, MT
Zoning & raw-land occupancy
Unclear - verifyNot confirmed whether Garfield County's unincorporated area has adopted a countywide zoning resolution under Montana's Title 76, Chapter 2 opt-in system. If it hasn't, raw land is likely unzoned; Jordan may have its own municipal zoning, also unconfirmed. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Garfield County-specific rule found for tiny homes or RVs; the Montana Building Codes Program (state) likely applies by default if the county hasn't adopted its own code. source
Building permits & codes
Unclear - verifyNot confirmed whether Garfield County enforces its own certified building code program; counties that haven't adopted one fall under the state Building Codes Program's jurisdiction per Montana Department of Labor & Industry. source
Septic & composting toilets
Generally allowedSeptic systems are permitted statewide through local health departments under Montana DEQ standards; Garfield County's sanitarian office would issue local permits, but county-specific rules/fees were not located. source
Greywater reuse
RestrictedNo Garfield County rule found; the Montana DEQ state baseline applies, allowing indoor greywater reuse without a permit through a compliant system, with limits on subsurface irrigation.
Rainwater harvesting
Generally allowedNo Garfield County restriction found on basic rooftop rainwater collection for personal, non-potable use; larger appropriations fall under Montana DNRC water-rights rules. source
Private wells & water rights
Generally allowedWells are permitted under Montana DNRC water-rights rules and licensed well-driller requirements from the Montana Board of Water Well Contractors; no Garfield County-specific well ordinance was found. source
Living disconnected from utilities
Unclear - verifyNo official Garfield County or Montana state source confirms or prohibits a fully grid- and utility-disconnected dwelling; it likely depends on unconfirmed county building/septic occupancy requirements.
