FieldOpValueNote
zoning_ordinance.manufactured_home_appearance_criteriacap_atreasonable_foundation_pitch_width_siding§89.020.2 authorizes 'reasonable appearance criteria' (permanent foundation, roof pitch, minimum width, exterior siding) but municipalities may NOT impose criteria that effectively exclude HUD-Code homes from districts that allow single-family residential use of comparable scale.
design_standards.modular_unit_treated_as_site_builtrequireTrueCompanion §700.027: modular units built to Missouri state code are equivalent to site-built for zoning purposes — cannot be excluded from any district that permits site-built dwellings of the same type.

Research notes

Permissive-enabling, not categorical preemption — weaker than Florida, North Carolina, or Texas equivalents. Per preemptions.md, §89.020.2 authorizes appearance criteria; it does not compel universal acceptance. Federal conflict check flagged because HUD National Manufactured Housing Construction and Safety Standards Act (42 U.S.C. §5403) preempts state/local construction-standards but reserves use/placement to local zoning. preemptions.md confirmation flag #5 calls the 2006 SB 644 enactment date subject to verification; the 2006-08-28 effective date is the standard Missouri Aug-28 effective date for legislation enacted in that session.
