HB 55 (Overdorf) and SB 284 (Perry) preempt local governments from adopting zoning and development regulations that require specific building design elements for single- and two-family dwellings, unless certain conditions are met. The bills define the term “building design elements” to mean exterior color, type or style of exterior cladding; style or material of roof structures or porches; exterior nonstructural architectural ornamentation; location or architectural styling of windows or doors; and number, type and layout of rooms.
