Life sciences real estate is a property type built for laboratory and research and development use by biotechnology, pharmaceutical, and medical device tenants. It carries specialized infrastructure, higher ceilings, heavy HVAC, and vibration control that ordinary office space lacks. Value depends on wet-lab readiness and tenant credit, not on floor area alone.
How Life Sciences Real Estate Works
Life sciences real estate works by delivering lab-ready shells that tenants finish with specialized fit-outs for wet chemistry, cold rooms, fume hoods, and clean rooms. Per Cushman and Wakefield, U.S. lab fit-out averaged roughly $741 per square foot in 2026, far above standard office build-outs.
Leases are typically triple net, so the tenant pays taxes, insurance, and operating costs on top of base rent. Because build-outs are costly, landlords fund large tenant improvement allowances. In the current tenant-favorable market, TI allowances range from about $150 to over $300 per square foot per industry fit-out guides, and higher allowances usually push effective base rent up.
Attribute | Life sciences | Standard office |
Primary use | Wet lab, R&D, GMP manufacturing | Desk and meeting space |
Fit-out cost | High, often $300 to $840+ per SF | Lower, often $50 to $150 per SF |
HVAC and utilities | Heavy, redundant, single-pass air | Standard building systems |
Lease structure | Typically triple net, long term | Gross or net, varied term |
Why Life Sciences Real Estate Matters
Life sciences real estate matters because a supply wave collided with slower demand, pushing vacancy to record highs and shifting leverage to tenants. Per CBRE, U.S. lab and R&D vacancy climbed to 23.2% in the first quarter of 2026, and JLL reported aggregate vacancy of 27.4% across its ten largest markets, up from 25.7% a year earlier.
The sector rewards operators who underwrite tenant credit and space quality over raw square footage. JLL estimates the more than 200 million square foot U.S. lab market needs 20 million to 25 million square feet of net absorption or supply reduction to return to equilibrium. An operator who buys generic space at office pricing can be stranded, because a shell without wet-lab infrastructure cannot capture lab rents.
Example
An operator leases 40,000 square feet of lab space at $65 per square foot triple net, funding a $200 per square foot tenant improvement allowance. The rule of thumb that every $10 of TI raises effective rent by about $0.80 to $1.25 annually over a ten-year lease sizes the rent lift.
Component | Amount |
Leased area | 40,000 SF |
Base rent | $65 per SF NNN |
Annual base rent | 40,000 x $65 = $2,600,000 |
TI allowance | $200 per SF x 40,000 = $8,000,000 |
Estimated rent lift from TI | $200 / $10 x $1.00 = about $20 per SF |
At roughly $20 per square foot of effective rent attributable to the allowance, the $8 million of TI is a major driver of the deal's economics. The example shows why life sciences underwriting centers on fit-out cost and TI, not on comparing price per square foot to nearby offices.
Variations and Edge Cases
Life sciences real estate varies by lab type, build path, and market, and an underwriter should confirm which applies before comparing deals. A gene therapy manufacturing suite and a dry computational lab carry different infrastructure and cost profiles despite sharing the category label.
Variant | Treatment |
Wet lab vs dry lab | Wet labs need plumbing, fume hoods, and single-pass air; dry labs resemble office |
GMP manufacturing | Gene therapy manufacturing fit-outs can exceed $1,200 per SF per fit-out guides |
Office-to-lab conversion | Conversions average about $300 per SF for build-out per Urban Land Institute reporting |
Build-to-suit | Remaining under-construction space is largely pre-leased build-to-suit per CBRE |
The most common misread is treating a life sciences building like Class A office because both look similar from the street. A building without wet-lab infrastructure cannot command lab rents, so the presence of lab-ready systems, not the address, sets the value.
Life Sciences Real Estate vs Class A Office
Life sciences real estate is often confused with Class A office because both are high-quality, professionally managed buildings. Life sciences real estate is built for laboratory work with heavy HVAC, vibration control, and fit-outs that can exceed $740 per square foot. Class A office is built for desk work with standard building systems and far lower build-out cost.
The practical difference is what the space can host. An office floor cannot run a wet lab without a costly conversion, and a lab building is overbuilt and overpriced for pure desk use. Underwriting a lab asset on office comparables understates both the build-out cost and the tenant credit risk that drive the category.
Frequently Asked Questions
What is life sciences real estate?Life sciences real estate is lab and research and development space built for biotech, pharmaceutical, and medical device tenants. It carries specialized infrastructure such as heavy HVAC, fume hoods, and vibration control that ordinary office space lacks, so it commands higher rents and higher build-out costs.
Why is lab vacancy so high?Lab vacancy is high because a large speculative construction wave was delivered into slower tenant demand. Per CBRE, U.S. lab and R&D vacancy reached 23.2% in the first quarter of 2026, and JLL reported 27.4% aggregate vacancy across its ten largest life sciences markets.
How much does a lab fit-out cost?Lab fit-out costs far more than office. Per Cushman and Wakefield, U.S. life sciences fit-out averaged about $741 per square foot in 2026, and gene therapy manufacturing suites can exceed $1,200 per square foot, versus roughly $50 to $150 per square foot for standard office.
