Mayor Michelle Wu’s proposal for rent stabilization would impact some of the city’s wealthiest neighborhoods.

Wu announced plans to cap annual rent increases at 10 percent during Wednesday’s State of the City speech. Rental units built after 2008 or in triple deckers would be exempt.

92% of Beacon Hill’s rental units would be subject to the mayor’s plans, the highest percentage of any neighborhood in Boston.

Rounding out the top 10 are: North End (91.3%), Back Bay (86.8%), Allston (77%), West Roxbury (76.7%), Fenway (74.5%), Longwood Medical Area (71.7%), Brighton (70.6%), Bay Village (65.15), and Mission Hill (61%).

Less impacted areas are: Dorchester (46.2%), South End (45.8%), Mattapan (45.5%), and Roxbury (37.7%).

The Seaport ranks at the bottom of the list of the city’s 24 neighborhoods at 19.3%.

“How ironic is it that Boston’s most sought-after and wealthy communities are the ones most impacted by initiatives meant to protect the most disadvantaged and needy?” asked one small Beacon Hill landlord.
