Flex Industrial Lease Abstraction
Flex industrial properties combine warehouse/distribution space with office space under the same roof, typically in a ratio ranging from 20%/80% to 50%/50% office-to-warehouse. These properties serve tenants who need both operational space for light manufacturing, storage, or distribution and office space for administrative functions, making them a hybrid product between traditional office and industrial leases. Flex industrial is one of the fastest-growing industrial subtypes due to its adaptability to a wide range of tenant uses.

Typical Lease Structure
Flex industrial leases are commonly structured as modified NNN or gross leases, with the landlord responsible for the structural shell and the tenant responsible for interior maintenance and operating costs within its space. CAM charges for flex industrial cover exterior maintenance, landscaping, and shared parking areas. Rent is typically quoted as a single blended rate per square foot covering both office and warehouse components, though some leases bifurcate the rate.
Typical Tenants
Technology hardware companies, light manufacturers, medical device companies, trade contractors, data and telecommunications service providers, creative production companies, and professional services firms requiring on-site storage or fabrication capabilities. The diverse tenant mix of flex industrial properties reflects the breadth of industries that need hybrid operational and administrative space.

Extraction Considerations
Flex industrial leases require extraction of the specific office-to-warehouse ratio, as this affects the applicable rent rate, insurance requirements, and permitted use parameters. Landlords of flex properties often restrict modifications to the office component separately from the warehouse, requiring granular extraction of the build-out and restoration provisions. Utility provisions must be extracted carefully, as the HVAC, power, and plumbing configurations of flex properties vary widely by vintage and location.
Frequently Asked Questions
What is the typical office-to-warehouse ratio in a flex industrial property?
Flex industrial properties commonly range from 10% to 50% office space, with the remainder as open warehouse or light manufacturing area. The ratio affects heating costs (office areas are typically fully climate-controlled while warehouse areas may be heated-only), insurance requirements, and permitted occupancy classifications. The ratio is typically defined in the lease or the floor plan attached as an exhibit.
Can flex industrial space accommodate hazardous materials storage?
Many flex industrial leases restrict or prohibit hazardous materials storage due to fire code compliance, environmental liability, and insurance constraints. Permitted use provisions must be extracted precisely to determine what materials and processes are allowed. Tenants with hazardous materials needs should verify local zoning, building code compliance, and fire suppression adequacy before occupying a flex space.
How are tenant improvements typically handled in flex industrial leases?
Flex industrial landlords frequently offer modest TI allowances for office improvements (typically $15–$40 per RSF), with the warehouse area delivered as a raw shell. Tenants are typically responsible for all warehouse build-out costs including specialized racking, electrical upgrades, and HVAC enhancements. Restoration obligations may require the tenant to remove improvements and restore to base condition at expiration.
