City or county?
Pin down exactly whether the address is inside Hot Springs city limits or unincorporated. It changes codes, minimum-size rules, and whether a THOW can be a permanent home.

The rules, honestly
The part nobody puts on a cabin brochure: where a tiny home is actually legal to live in, and what the health department needs to sign off.
The single biggest regulatory variable for a tiny home here is whether the parcel sits inside the City of Hot Springs or in unincorporated Garland County. Inside the city, expect enforced building codes and, in most places, minimum dwelling standards — which can make a very small home or a THOW difficult or impossible to establish as a permanent residence. In the unincorporated county, residential code enforcement has historically been lighter, which is a real part of the area's appeal to small and off-grid builders. But "historically lighter" is not a legal guarantee: verify the current rules directly with Garland County and by web search before you commit, because ordinances change and this page hedges on purpose.
Regardless of code enforcement, two things apply everywhere in the county: septic approval from the Arkansas Department of Health and floodplain regulations. A parcel with light building rules but soil that won't support an approved septic system is not a shortcut — it's a dead end.
Due diligence
Answer these before earnest money, not after.
Pin down exactly whether the address is inside Hot Springs city limits or unincorporated. It changes codes, minimum-size rules, and whether a THOW can be a permanent home.
A tiny house on wheels is often treated like an RV or park model, which can limit permanent occupancy on residential land. Ask the county specifically about THOW placement — don't assume.
Confirm the soil will support an Arkansas Department of Health-approved septic system (or approved alternative). Rocky Ouachita lots sometimes need pricier engineered systems.
Check FEMA floodplain maps and any setback or easement limits. Floodway parcels and access problems are hard stops for both permits and lenders.
How your tiny home is classified drives how you pay for it. A tiny home on a permanent foundation is real property and can sometimes be financed like a small house — though small loan amounts and appraisal comps can still make lenders cautious. A THOW, classified closer to an RV, is usually bought with a personal loan or RV loan rather than a standard mortgage, often at higher rates and shorter terms. Neither path is wrong; they're just different, and knowing which one you're on before you shop keeps the numbers honest.
