US Rental Market Shows Diverging Trends in Rust Belt and San Francisco

Several Rust Belt cities are experiencing a revival in the multifamily housing sector as tech jobs expand. In Pittsburgh, Google’s growth at the Bakery Square campus and a strong academic base have helped lower vacancy rates to 2.4% and push Class A rents up 11.2% in 2021. Detroit’s economy is also rebounding, with similar gains in rental demand.

At the opposite end of the spectrum, San Francisco has become the most expensive U.S. market for two‑bedroom rentals, with median rents rising to $6,020—a 25.9% year‑over‑year increase. The surge is linked to hiring in the artificial‑intelligence sector and a sharp drop in available rental inventory, while nearby Bay Area cities also see rent pressures.

Both regions illustrate how tech‑driven employment and limited housing supply are reshaping rental markets across the United States.
