The sure signs of spring have arrived: birds chirping, grass greening and waves of homebuyers filling up the market.

To satisfy the inquiring minds of hopeful buyers and home-improvement aficionados, the Minneapolis and St. Paul Home Tour will open the doors to more than 50 homes across the two cities this weekend, with an emphasis on historic homes, creative renovations, remodeling and urban landscaping.

Added this year are two examples of homes rehabbed by the Inspiring Communities program, which was established by the Saint Paul Housing and Redevelopment Authority in 2013. The program focuses on rehabbing clusters of homes located in neighborhoods disproportionately impacted by foreclosure and high vacancy rates.

The two Inspiring Communities homes are located across the street from one another at 689 and 688 East 4th Street.

The tour, now in its 28th year, was started by the City of Minneapolis to encourage people to not flee the city for suburban living. The City of St. Paul joined the cause and the tour the following year.

The home tour hours are 10 a.m. to 5 p.m. on Saturday and 1 p.m. to 5 p.m. on Sunday.
