Life Science & Biomedical Wet Lab Real Estate Financing
The life science real estate sector requires specialized infrastructure that cannot be duplicated in standard office buildings: advanced single-pass 100% outside air HVAC systems, heavy structural floor vibration damping, chemical fume hood exhaust shafts, acid neutralization piping, and biosafety cleanrooms (BSL-1 to BSL-3). BancorpOne structures customized debt facilities—including office-to-lab conversion loans, speculative wet-lab construction debt, and permanent core campus mortgages—across premier biotech clusters and emerging life science hubs.
Indicative Underwriting Matrix
Life science underwriting requires mechanical, electrical, and plumbing (MEP) engineering audits, chemical containment permits, and tenant venture capital funding verification.
Financing Specialized Lab Infrastructure and Heavy Mechanical Specifications
Converting conventional commercial office properties into wet laboratories requires extraordinary capital investment, typically $250 to $500+ per square foot. Essential specifications include floor-to-floor ceiling heights of 14 to 16+ feet (to accommodate massive supply and exhaust ductwork), reinforced floor loading (100 to 125 lbs/sq ft) for heavy centrifuge and imaging equipment, and vertical shaft space for chemical exhaust risers.
BancorpOne provides delayed-draw term loans that fund laboratory conversions in tranches as specialized spaces deliver. We structure leases with substantial tenant restoration obligations and evaluate the venture capital funding backing early-stage clinical biotech tenants.
- Funds BSL-2 and BSL-3 wet laboratories, vivariums, pharmaceutical R&D, and cleanroom manufacturing
- Underwrites mechanical systems: 100% single-pass air, emergency standby diesel generators, and DI water loops
- Financing available in premier innovation corridors (Boston/Cambridge, San Diego, SF Bay Area, RTP) and secondary hubs
- Flexible interest-only bridge terms during multi-year entitlement, MEP buildout, and commissioning phases
Biotech Tenant Credit Analysis and Venture Capital Due Diligence
Unlike traditional corporate tenants with years of profitable EBITDA, pre-revenue biotechnology firms rely on Series A/B/C venture rounds, NIH research grants, or big-pharma development partnerships. Underwriters assess tenant cash burn rates, clinical trial pipeline stages (Phase I-III), and security deposit letters of credit.
Frequently Answered Financing Questions
Verified answers to common borrower and broker inquiries regarding loan sizing, guidelines, and execution.
How much does it cost to convert a standard office building into a wet lab?
Office-to-lab conversions typically cost $250 to $500+ per square foot due to heavy 100% outside air HVAC systems, chemical piping, and emergency power.
Our delayed-draw conversion loans provide future-funding reserves specifically to finance these heavy mechanical improvements.
Size a Lab Conversion Loan →How do commercial lenders underwrite early-stage, pre-revenue biotech tenants?
Lenders evaluate venture capital backing, remaining cash runway, NIH grant funding, and require substantial security deposit letters of credit (6-12 months rent).
Multi-tenant research campuses blend venture-backed startups with established publicly traded pharmaceutical anchors to balance credit risk.
