Historic Comparison
Executive Summary
Houston’s medical office building sector remains a vital component of the region’s healthcare landscape, supported by strong demand and steady institutional investment.
Strong leasing activity has kept pace with new deliveries, pushing vacancy rates lower both quarter over quarter and year over year. For fourth quarter, vacancy dropped to 10.9%, the lowest on record since 2019. The uptick is supported by both a positive net absorption of 376,898 square feet – outpacing the 272,856 square feet of new deliveries during the quarter – and a growing construction pipeline. For the year, the medical office buildings sector gained 667,198 square feet of net absorption and delivered 483,061 square feet of new space.
RevistaMed, a national medical property database provider, shows Houston jumping to the No. 1 ranking for medical office square footage under construction among the Top 50 markets and maintaining the No. 4 spot for year-over-year net absorption. The past 18 months have shown slower absorption, likely tied to reduced quarterly completions. Even so, vacancy has continued to slowly decline during the last several years.
