Descriptiontext

Estes Park Housing Authority (EPHA) is a political subdivision of the State of Colorado, founded in 1999, that administers affordable rental, homeownership, and assistance programs for income-qualified households in the Estes Park valley. It operates a portfolio of nine deed-restricted rental communities — Cleave Street Apartments, Falcon Ridge, Lone Tree Village Apartments, The Pines Apartments, Talons Pointe Apartments, Beaver Brook Crossing, Fall River Village, Grand Estates Apartments, and Peak View Apartments — and runs homeownership programs including Vista Ridge Condominiums and the Estes Valley Workforce Housing Assistance down payment program. Its technical footprint is limited to a public website (esteshousing.colorado.gov), a Mapme-based housing options map, a Substack newsletter, a YouTube channel for board meeting recordings, and a Google Drive repository for board materials.

EPHA is funded primarily through rental income from deed-restricted units, program fees associated with homeownership assistance, and state appropriations under Colorado's Proposition 123 (a 2022 voter-approved initiative dedicating 0.1% of state income taxes to affordable housing, administered 60% by OEDIT and 40% by DOLA). The authority is governed by a publicly elected/appointed board that meets monthly, with joint study sessions held with Town of Estes Park Trustees. EPHA is pursuing Ballot Initiative 6E (Lodging Tax Extension) to expand its local revenue base, and its Fall River Village property serves as the first-in-the-nation pilot site for the Colorado Renter Rewards Program, which provides 2% cash back on monthly rent, free credit reporting, and a nontaxable annual savings match via a partnership with the Stake app platform. The customer base is narrow by design — low-to-moderate-income renters and first-time homebuyers in a single mountain valley — and pricing for deed-restricted units is set by income-based eligibility criteria rather than market forces.
