Here’s some recent data from RENTCafe looking at the supply of new multifamily rental apartments in the US. About 334,000 rental units are expected to be completed and occupied this year, which is a decline from the 2018 peak of 357,000 units, though still a relatively high number. This year is expected to be the fifth consecutive year where supply is greater than 330,000 units. Below you can also see how this breaks down across the largest MSAs (metropolitan statistical areas).

For this study, RENTCafe looked at new apartment construction data for buildings with 50 or more units (so no smaller infill projects). It covers 109 US metro areas. To determine whether a building is likely to be completed in 2021, they looked at confirmed certificate of occupancies and also used some sort of fancy algorithm to predict the likelihood that an under construction project will get one before the year is out.
