Neighborhoods in cities with lively social scenes, good amenities, and prime locations are reaping the benefits of the flood of new multifamily construction that has come on the market in recent years.

Some 1.2 million new rental units have been delivered since 2018, according to an analysis by RentCafe, and a few zip codes with above-average incomes and younger populations have been the winners by the number of new units added.

Two zip codes in Washington, DC claimed the largest number of new rentals. Zip code 20002, which incorporates the U.S. Capitol and includes the H Street Corridor, saw the most construction in the nation. Its location places it "at the heart of political, cultural and social scenes," RentCafe noted. Median income is $79,460 and the median age of 33.5 years has additional appeal for young renters. Land available made it a good candidate for development: the 7,378 units added represented a 73% increase over the five years.
