Jamison Properties, a prolific converter of mid-sized, older office properties into apartment buildings in Los Angeles, is preparing to convert a 32-story office tower in downtown L.A. into 686 apartments.

The Los Angeles-based company, with a portfolio that includes 10 adaptive reuse developments in Southern California, says its plan to convert the L.A. Care tower at 1055 W. 7th Street will be a “game changer” because it will involve “very little structural retrofit.”

Jamison said the ability to convert the Care tower, built in 1987, without going through a full structural retrofit will reduce construction costs by about 10% and save a lot of time compared to the company’s previous conversions of mid-century office buildings, which required significant structural improvements to meet L.A.’s seismic codes, the Los Angeles Times reported.
