Captive Insurance for Mixed-Use Properties: How the Cell Structure Works
Mixed-use properties put apartments, shops, offices and parking in one development. Each use has its own risk and its own insurance market. That is exactly why the cell structure is a natural fit for captive insurance for mixed-use properties.
The mixed-use insurance stack
A typical development with apartments over ground-floor retail and a shared garage carries several lines:
Residential property and liability for the units, residential common areas and the owner’s liability to residents
Commercial property for the retail space, commercial common areas and the garage
Commercial general liability for the owner as landlord of commercial space
Workers’ compensation for the management and maintenance team
Umbrella over the residential and commercial liability
In a traditional program, these are often placed with different carriers, and what isn’t spent on claims on each line goes to each carrier.
What a cell structure is
A cell structure is one insurance company divided into separate cells. Each cell has its own premium, claims and results. In domiciles that allow protected cells, each cell’s assets and liabilities are legally separated from the others. The cells share the company’s administration, compliance, claims handling and reinsurance.
How cells fit mixed-use
Residential
The residential side has the most predictable, highest-volume premium: the apartments, the residential common areas and the resident liability program. It is usually the easiest place to start. Our programs have consistently averaged 75% to 93% resident enrollment over time.
Commercial
Retail and office risk varies more by tenant. A restaurant is a different liability exposure than a dentist’s office. Keeping commercial risk in its own place means a bad year in one use doesn’t hide a good year in the other.
Operator
Your management team’s workers’ compensation and professional lines can sit in their own layer as well.
Don’t forget tenant insurance
Commercial tenants carry their own policies. Your leases should require proof of coverage and name you as an additional insured where appropriate. That coverage doesn’t become part of your captive, but it shifts tenant-caused losses to the tenant’s insurer, which protects your results.
Adding a cell to what you already have
You don’t have to move everything at once. Many owners start with the residential layer and add the owner and operator layers later. Our guide on adding an insurance cell to an existing structure covers the steps.
Where Insur3Tech fits
Insur3Tech’s captive uses a cell structure for residents, owners and operators. There is no minimum premium and no unit minimum; portfolios as small as 4 doors can join. There are no holdout periods. The entire program is reinsured, so you carry no downside risk. What isn’t spent on claims comes back to you.
