Research notes
Cities may require permanent foundation, removal of transport hardware, and uniformly-applied design compatibility standards (roof pitch, siding, eave overhang) provided they apply equally to site-built homes. Modular homes (state building code, not HUD code) are treated as site-built under §39-4301 et seq. and are categorically not excludable. HB 800 (2026) extends parity into multifamily-zoned land for manufactured duplexes and lowers the practical floor against single-section units in single-family zones.
