CO HB1091

Prohibits unit owners' associations from adopting new provisions that ban fire-hardened building materials, though associations may impose reasonable standards on design, dimensions, placement, or external appearance of fire-hardened fencing materials.

Limits association review and approval periods for fire-hardened building material fencing applications to sixty days, with automatic approval if not denied or returned for modifications within that timeframe; denials must be detailed in writing and not arbitrary or capricious.

Restricts association standards for fire-hardened fencing to increases of no more than ten percent in cost compared to other fire-hardened building materials, and permits only bona fide safety requirements consistent with building codes or nationally recognized safety standards.

Defines fire-hardened building materials as those meeting criteria from the International Wildland-Urban Interface Code (sections 504-506), NFPA Standard 1140 and 1144, or IBHS wildfire-prepared home requirements.
