Local Grants & Incentives in Fort Collins

Larimer County Affordable ADU Permit-Fee Waiver (2026)

Larimer County will waive building permit fees for new ADUs if the owner commits to renting at an affordable rate — the county estimates savings of roughly $3,000–$14,000 per project. Funded by a $105,000 Colorado ADU Grant, it is expected to cover about 8–10 units in unincorporated Larimer County and launch in mid-2026. City of Fort Collins lots may not qualify; confirm eligibility with the County.

Value: $3,000–$14,000 waived

Colorado ADU Finance Program (CHFA)

New $8M state program of relending, interest-rate buydowns, and credit enhancement so participating lenders can extend ADU loans to low- and moderate-income Colorado homeowners in DOLA-certified ADU-supportive jurisdictions. Rolling out to residents in 2026 — ask lenders whether they participate.

Value: Rate buydown + relending

Accessory Dwelling Unit Grant Program (ADUG)

DOLA grants awarded to local governments that support ADUs. Homeowners benefit indirectly through pre-approved plans, fee waivers, and streamlined review in jurisdictions that win awards. Confirm whether Fort Collins or Larimer County participates.

Value: Varies (via jurisdiction)
