CO HB1313

Replaces the current 3% annual affordable housing growth requirement with a new "target increase number" formula beginning January 1, 2027, calculated by multiplying average annual housing permits by years in the cycle, then by 0.10, 0.15, or 0.20 based on whether the county's job growth rate is below, at, or above the statewide median

Creates a "good faith effort waiver" for governments unable to meet the 3% requirement for the 2024-2026 cycle, available to those achieving at least 65% of required increases and meeting other conditions, with applications accepted June 15 - November 1, 2026

Establishes an "adjustment waiver" for governments unable to meet targets beginning in the 2027 cycle, requiring detailed documentation of barriers such as housing needs assessments, infrastructure limitations, or environmental constraints

Provides bonus unit credits toward housing targets: 0.10 additional unit for development on government-donated land, 0.20 for units developed for sale, and 0.20 for units restricted to households at or below 30% of area median income

Allows counties to count affordable housing units as up to 1.15 units when the development qualifies for property tax exemptions reducing county revenue and the county provided no funding for the project
