Tiny home rules in Carmel, IN — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Carmel's UDO allows manufactured/factory-built homes in single-family and two-family districts only if they exceed 950 square feet of occupied space, meet the district's minimum size, and sit on a permanent foundation below the frost line. Movable tiny houses on wheels and RVs are not allowed as permanent dwellings outside an approved manufactured home park, making most 'tiny homes' infeasible without a variance.
Carmel does not have a tiny-home category; it regulates small factory-built dwellings under UDO Section 5.24, Manufactured Home Standards. Manufactured homes are permitted in any area zoned for single-family or two-family dwellings, but in subdivisions not platted for them they may not exceed 10 percent of the platted lots. A manufactured home must: meet the minimum square footage of the district; be larger than 950 square feet of occupied space (or the district minimum, whichever is greater); be permanently attached to a solid foundation extending below the frost line a minimum of 32 inches (or on basement walls) with the under-floor area fully enclosed; be clad in approved siding (lap, wood, pressboard, stucco, block, or stone); and have a residential-style pitched roof. A unit not meeting these terms is allowed only with a Board of Zoning Appeals variance or within an approved manufactured/mobile home park. Because most tiny houses on wheels are under 950 square feet, lack a permanent below-frost foundation, or are titled as recreational vehicles, they cannot serve as a permanent primary dwelling on a typical Carmel lot without zoning relief. Inhabited mobile/manufactured homes outside an approved park may not connect to utilities except units offered for sale.
Placing a tiny house on wheels, RV, or undersized manufactured home as a permanent residence outside an approved park, or without a variance, violates the UDO and can lead to removal orders, utility disconnection, and zoning enforcement.
