Idaho cities and counties may offer a simpler process to split land containing a secondary home when a lender requires separate parcels for financing.
Cities and counties may let owners split land with an existing or approved secondary home for financing without a full subdivision process. A lender must confirm the need.
A financing split does not authorize extra homes or further land splits. Recorded restrictions stay with the land, and owners cannot bypass them through repeated splits.
Cities and counties may offer a land-splitting process handled by local officials without the usual subdivision map requirements. The land must contain an existing or approved accessory dwelling unit, meaning a secondary home, or another secondary residential structure. A lender or mortgage underwriter must provide a letter showing that separate parcels are required for financing. The split must serve only mortgage or financing purposes and stay within local housing density limits. Each resulting parcel must have legal access and utility service that meet local standards. The law took effect on July 1, 2026.
These land splits must be recorded with the county recorder, along with a declaration restricting further splits or development that conflicts with these rules. The limits stay with the original land and cover both resulting parcels, including when ownership changes. Owners cannot bypass the limits by transferring, rearranging, or recombining parcels and splitting them again. The process preserves agricultural land protections and does not allow new building lots that violate local zoning or housing density rules.
