MODERATE
This bill updates Montana's laws to ensure manufactured and factory-built housing are treated the same as traditional homes in zoning decisions. It establishes a legal presumption that placing these homes in residential areas will not lower property values and clarifies definitions to include specific types of factory-assembled structures.
Scope change
The bill expands the scope of protected housing types by explicitly including 'factory-built housing' (non-HUD certified structures meeting state inspection standards) alongside traditional manufactured housing in zoning regulations.
DEFINITION

Updated the definition of 'factory-built housing' to include structures that are not HUD certified but meet state inspection requirements, broadening the category of protected housing.

REQUIREMENT

Added a rebuttable presumption that placing manufactured or factory-built homes in residential zones will not adversely affect property values, shifting the burden of proof to those claiming harm.

Included 'tiny dwelling units' (350-750 sq ft) as an allowable zoning district type, aligning manufactured housing rules with emerging housing trends.

ENFORCEMENT

Clarified that zoning regulations cannot treat manufactured or factory-built housing differently from other residential units, reinforcing equal treatment across all housing types.
