Delaware Street Commons, a co-housing complex in the 1200 block of Delaware Street, will host a “Common House Warming” event Saturday in the complex’s common house.

A potluck dinner will begin at 5 p.m. and last until 7 p.m., followed by music and dancing until 9 p.m.

“Anyone who has supported, encouraged or wants to wish us well is invited,” said Vicki Penner, the complex’s membership coordinator.
