City of Longmont Affordable Housing Program

In 2015, the Longmont community began a two-year planning effort, coming together to document hopes for the City’s future and to outline the path to reach those goals. Envision Longmont, a multimodal and comprehensive plan, provides strategic direction and guidance for Longmont over the next 10 – 20 years. Providing housing for all is an interwoven theme throughout the Envision Longmont comprehensive plan. The plan includes the goal of providing a range of incentives for development that includes affordable housing units. This page includes both the requirements for affordable housing and the incentives that have been created to implement the housing goals of Envision Longmont. For a complete list of current code requirements, see the City’s Municode website.

Minimum Affordable Housing Requirements

For-Sale Projects: 12% of all residential units in new development should be affordable to low- and moderate-income residents (households at or below 80% of the Area Median Income (AMI) by selling for a price determined by the City, updated annually).

Rental Projects: 12% of the rental units must be permanently affordable to households at or below 50% of the Area Median Income (AMI). Depending on the project’s agreement with the City, unit rents must follow one of two rental standards: CHFA or HOME. Please consult your agreement with the City to determine which rent standard your project uses.

Ways Developers Can Satisfy the Requirements

On-site: Provide required affordable housing within the development
Fee-in-Lieu: Pay square-footage fees to the City’s affordable housing fund
Off-site: Build the required affordable housing in another location
Land Donation: Donate land to the City or a non-profit housing developer
Voluntary Alternative Agreement: A developer and/or builder can propose to City Council an alternative way of meeting the requirements that are not in the Ordinance
Redemption of Credit: A developer and/or builder may acquire Surplus Unit credits from another developer/builder that built more than the minimum required affordable units and was issued credits by the City.
Middle-Tier or Attainable Housing: Provide housing units that are affordable for households earning 80-120% AMI to reduce the required affordable units. A Voluntary Alternative Agreement is required.

Some options require approval of City Council. More information regarding affordability requirements may be found on the City’s Inclusionary Housing page.
