Affordable and Attainable Housing Tax

Have an idea for a bold housing solution? The Housing Innovation Fund is accepting applications until Dec. 4, 2025. Learn more and apply today.

Overview

In the 2023 General Election, Boulder County voters approved an extension of an existing .185% sales and use tax with 71% support. Named the Affordable and Attainable Housing Tax (AAHT), it will continue for 15 years to help fund affordable housing and related services across Boulder County.

Money from this tax supports:

Building, repairing, and maintaining homes for low- and moderate-income families and local workers
Creating and maintaining supportive housing for people who need help staying housed
Providing services that promote housing stability
Giving grants to housing authorities, nonprofits, and local cities and towns to expand affordable housing options

To learn more, read the resolution approved by the Boulder County Board of County Commissioners in support of the tax.
