About ARCH

Who we are

Since 2005, ARCH has transformed the way our community looks at housing affordability. By purchasing, restoring, and building properties in Blaine County, we are able to welcome into the neighborhood our teachers, police officers, hospital technicians, firefighters, nurses, and others who serve the community.

By remaining committed to our mission of developing permanent solutions to housing affordability, ARCH improves the quality of life for hardworking families who, in a more typical community, would not need housing assistance. We ensure that the people who serve this community can afford to live here.

This commitment to empowering our community is carried out through programs that strengthen foundations, provide opportunities, advance economic vitality and promote cooperation within our community.

Our Vision

To create a thriving, sustainable, year-round community in Blaine County.

Our Mission

To develop, safe, permanently affordable housing for persons of low to moderate-income and to work with all interested public and private parties towards this objective.

Our Values

Honesty, Integrity, Citizenship, Enhancement, Community, Affordability, Quality

Our Principles

To deliver high-quality affordable housing.
To balance effective use of resources with the delivery of attractive, long-lasting housing.
To integrate workforce housing compatible with surrounding neighborhoods.

Our History

Originally an advocacy group, ARCH was formed in 2005 by founder, past Board President, and current Advisory Board Member, Rebekah Helzel. The organization focused on educating policymakers, employers, and the public at large about the need for permanent housing affordability solutions and the resulting problems if affordable housing is unavailable.

In 2007 we amended our bylaws and IRS application to become a Community Land Trust (CLT) with a view to actively acquire land and homes to ensure ongoing affordability. We are a member of the National CLT Network.

Also since 2007 we have been certified as a Community Housing Development Organization (CHDO) by the Idaho Housing Finance Association.
