The state has added 20 more low-income rental homes for seniors to a 60-unit complex in Kapolei that opened last year.

New one- and two-bedroom units at The Senior Residence at Kapolei will rent from $318 to $522 a month for seniors earning no more than 50 percent of the median income for Honolulu, with some tenants earning no more than 30 percent of the median income.

Financing for the project was provided by state and federal sources, including the Hawaii Housing Finance and Development Corp., a state agency that contributed $1 million from its Rental Housing Trust Fund. The agency also contributed the land for the project under a lease for $1 a year.

The federal Department of Housing and Urban Development provided $4.4 million from its Section 202 Supportive Housing for the Elderly Program, and is providing rental subsidies for tenants. Pacific Housing Assistance Corp. developed the project, which will remain affordable for 75 years.

A grand opening and blessing for the project was scheduled for 10 a.m. today. The 60-unit first phase opened in May 2009.
