Summary
Henderson caps a tiny-house accessory dwelling unit at 400 square feet, exempts it from matching the main house's design in the rear yard, and requires a permanent foundation.
Accessory dwelling units shall be no more than 25 percent of the floor area of the principal dwelling or 1,000 square feet in size, whichever is greater, except that a tiny house may be no larger than 400 square feet (excluding lofts)... If located in the rear yard, a tiny house is exempt. A tiny house must be placed on a permanent foundation.
Full Breakdown
Henderson's Development Code lets a tiny house count as an accessory dwelling unit on a lot with a principal home. It's capped at 400 square feet (lofts excluded), smaller than the standard 1,000-square-foot or 25%-of-principal-floor-area ADU limit. Placed in the rear yard, it skips the rule requiring accessory structures to match the main house's materials, roof and color, but it must sit on a permanent foundation, not wheels or blocks. Only one ADU per lot is allowed.
Violations & Fines
Building code and zoning compliance is enforced by the Community Development and Services Department; a tiny house without a permanent foundation, over 400 square feet, or added as a second ADU on the lot is not permitted and requires correction before final inspection or occupancy.
