The Life Sciences Real Estate Reset: How to Evaluate and Reposition Existing Assets

Owners and investors evaluating existing life sciences real estate need a connected view of four things before committing capital: market fit, environmental and site conditions, building capabilities, and long-term operating needs.

That information helps teams decide whether to acquire, retain, reposition, improve, repurpose or exit an asset.

Why Are Existing Life Sciences Assets Back at the Center of the Market? 

After years of rapid development, the U.S. lab market is carrying more space than current demand can absorb. CBRE reported national lab/R&D vacancy at 23.8% in Q2 2026, while average triple-net asking rent fell 8.1% year over year. Demand indicators improved, but available supply continues to influence owner, investor and operator decisions. 

JLL’s June 2026 U.S. Lab Property Report described an early recovery with persistent oversupply. It found that more than 6.2 million square feet of lab space had already transitioned into other property types, with more repositioning ahead. JLL also reported that direct available lab space in buildings completed in 2020 or later fell by 2.6 million square feet between Q2 2025 and Q1 2026, while availability increased in older buildings. The report said tenants are trading up to the best available product and choosing building quality. 

That flight to quality raises a more difficult question for owners of existing assets: which buildings can become competitive through targeted investment, and which may be better suited for another use?  

What Should Owners Evaluate Before Repositioning Life Sciences Real Estate? 

A repositioning decision begins with the asset, not the design concept. The following areas should be considered together because each can change feasibility, budget, schedule and long-term value. 

Environmental and Site History 

Prior uses can shape what additional evaluation may be needed before acquisition or renovation. A clear record of site history and known environmental conditions helps the team understand where uncertainty remains and whether further due diligence should be built into the decision process. 

Building Condition and Infrastructure 

The structure, envelope, roof and major mechanical, electrical and plumbing systems should be reviewed against the intended use.

Capital Needs and Intended Use 

Repair, replacement and improvement needs should be considered alongside the proposed occupancy plan and hold strategy. Connecting these inputs early helps owners distinguish between a manageable improvement program and a conversion that asks more of the building than the business case can support. 

When Can Adaptive Reuse Create Value for a Life Sciences Property? 

Office and industrial buildings can present potential repositioning opportunities when location, basic structure and access support the strategy. Adaptive reuse can also expose conditions that were less important under the prior use.

Where Adaptive Reuse Risk Can Emerge 

• Environmental conditions tied to prior use 

• Hazardous building materials 

• Ventilation, power, water, controls and structural capacity 

• Deferred maintenance and near-term capital needs 

Renovation may uncover conditions that affect cost and sequencing, while the intended use may require major changes to building systems. Early review will not remove every uncertainty, but it can identify the issues most likely to affect feasibility while the owner still has options. 

When Can Adaptive Reuse Create Value for a Life Sciences Property? 

An existing facility’s value depends on how it performs after renovation as well as what it costs to convert. The U.S. Department of Energy notes that laboratories use far more energy and water per square foot than offices and other facilities because their activities are energy-intensive and their health and safety requirements are more stringent. 

Energy benchmarking can establish a performance baseline. Existing building commissioning, including retro-commissioning, can help verify that complex systems operate as intended, while MEP assessments can identify conditions that may affect reliability, tenant experience or future capital needs.

These activities provide additional information to test the investment thesis against actual building performance. They can provide clearer information for leasing discussions, capital budgeting and long-term ownership decisions.

How Should Sustainability Fit Into Capital Planning? 

Sustainability goals are easier to act on when they are tied to the same capital plan that governs repairs, tenant improvements and system replacements. An integrated plan can identify where energy, resilience and long-term asset priorities overlap. 

For some properties, the priority may be improving existing systems before major replacement. For others, current performance, planned occupancy or asset condition may support a larger intervention. The sequence should reflect available capital, operating needs and the owner’s hold strategy. 

Keeping sustainability connected to asset strategy places efficiency, reliability and environmental priorities alongside the costs and timing that determine whether a building can remain competitive. 

What Information Supports Better Capital Decisions? 

In today’s life sciences market, creating value is less about simply adding space and more about understanding what you already have and making smarter decisions about where to invest, reposition and improve. 

Acquisition 

Connect market assumptions with environmental and building conditions before pricing and closing decisions are finalized. 

Repositioning 

Test the intended use against the asset’s physical and operating requirements before the design and construction scope expands. 

Portfolio Planning 

Compare capital needs and performance across properties so limited investment can be directed to the assets that best support the strategy.
