Boston Metro Life Science Figures Q2 2026

The Greater Boston lab market posted its first quarter of positive net absorption since Q3 2025 in Q2 2026, offering a tentative sign of stabilization amid persistent headwinds. Total market availability edged up 10 basis points quarter-over-quarter to 32.8%, up 60 basis points year-over-year from 32.2% in Q2 2025, while vacancy increased 70 basis points quarter-over-quarter to 28.7%, now 250 basis points above the 26.2% level recorded one year prior. Net absorption registered a modest positive 4,141 sq. ft.—an improvement from the 117,186 sq. ft. of negative absorption recorded in Q1 2026—though year-to-date absorption remains negative at 113,049 sq. ft.

Despite the positive quarterly absorption figure, overall market conditions remain tenant-favorable. Cambridge drove the bulk of the improvement, posting nearly 194,000 sq. ft. of positive absorption, while suburban submarkets contracted. Rents extended their decline for a fourth consecutive quarter, and vacancy rose further from the prior period, underscoring the fragility of any nascent recovery and the continued imbalance between supply and active demand.
