MO HB664

Replaces the definition of "blighted area" with a narrower standard requiring structures to have unrepaired housing, maintenance, or building code violations affecting safety (roof, foundation, utilities, fire protection, etc.) where repair costs exceed 50% of the property's assessed value.

Prohibits use of eminent domain solely for economic development purposes; "public use" is limited to public possession/enjoyment, public utilities, common carriers, or acquisition of abandoned or blighted property, excluding economic benefits like tax revenue increases.

Requires condemning authorities to individually evaluate each parcel in a redevelopment area to determine if it meets the statutory definition of blight before condemnation can proceed.

Establishes a five-year deadline from redevelopment plan authorization to file condemnation petitions; if not filed within five years or if a parcel doesn't meet blight criteria, the authority to acquire that property expires and must be reauthorized.
