Infill Infrastructure Grant Program (IIG)



(916) 263-2771


Funded by Proposition (Prop 1C) 1C, the Housing and Emergency Shelter Trust Fund Act of 2006, the primary goal is to promote infill housing development. By providing financial assistance, IIG supports infrastructure improvements to facilitate new infill housing development. IIG serves to aid in new construction and rehabilitation of infrastructure that supports higher-density affordable and mixed-income housing in locations designated as infill. Infill project sites must have been previously developed, or largely surrounded by development.

Important Updates

Assistance Type

IIG is grant assistance, available as gap funding to infrastructure improvements required for specific residential or mixed-use infill development. Funds will be allocated through a competitive process, based on the merits of the individual infill projects and areas. Some of the application selection criteria includes housing density, project readiness, access to transit, proximity to amenities, and housing affordability.

Assistance Terms

For Qualifying Infill Projects, the Program grant amount shall not be less than $500,000 or $250,000 Rural Areas. The maximum Program grant amount shall not exceed $5 million for each application. The Department will fund only one application for each Capital Improvement Project or portion thereof. In each NOFA, the Department will fund only one application for each Qualifying Infill Project.

Eligible Activities

To be eligible for funding, a Capital Improvement Project must be an integral part of, or necessary for the development of a Qualifying Infill Project. Program grant funds must be used for reasonable and necessary costs of the Capital Improvement Project. Eligible activities include new construction, rehabilitation, and acquisition of infrastructure.

Eligible Applicants

Non-profit or for profit developers are required applicants, either solely or as a joint applicant with a Locality or public housing authority with jurisdiction over the area in which the Qualifying Infill Project is located.
