Even before a new senior housing community in Elk Grove was complete, Eric and Avilla Hayman had signed up to live there. “We were very excited,” said Avilla Hayman, 64. “We were just waiting for the building to be built.” The building, Vintage at Laguna II, is Elk Grove’s newest offering in a bustling market: affordable apartment-style living for low- and moderate-income elderly people. The 69-unit community at Laguna and Big Horn boulevards has one- and two-bedroom apartments for active seniors 55 years and older. It was completed despite the disappearance of state redevelopment funds, instead subsidized by the city with money earmarked for low-income housing. The community is the second one built in Elk Grove by USA Properties Fund, a for-profit developer of affordable housing based in Roseville. USA already developed and owns the adjacent Vintage at Laguna, a 158-unit senior community that opened in 2005. Residents must earn between 30 percent and 60 percent of the median income for Sacramento County. Rents range from $383 for a one-bedroom apartment to $973 for a two-bedroom unit, depending on the resident’s income.
