Mixed-use buildings split costs between retail, office, and residential tenants. Cross-subsidization between uses is the biggest overcharge risk.
A mixed-use development combines residential, retail, office, and sometimes hospitality uses in a single integrated property. These projects share infrastructure like parking garages, lobbies, and mechanical systems across different use types. CAM allocation in mixed-use properties is among the most complex, as costs must be fairly divided between fundamentally different occupant types.
Typical Lease
Varies by use type (NNN for retail, Modified Gross for office, condo structure for residential)
Avg CAM/SF
$8.00 to $22.00 (varies by component)
Mgmt Fee %
4% to 7%
Mixed-use CAM requires a multi-tier allocation. First, shared building costs (structural, parking, core systems) are split between use types based on square footage or a negotiated formula. Second, use-specific costs are allocated among tenants within each component. This two-tier structure creates numerous opportunities for misallocation.
Amenities like pool maintenance, fitness centers, or concierge services primarily serving residential tenants may be included in the shared building cost pool, forcing commercial tenants to subsidize residential benefits.
Retail and residential users typically generate different parking demand patterns. If garage costs are split purely by square footage without accounting for usage intensity, one group subsidizes the other.
Mixed-use landlords may not disclose the formula for splitting costs between use types. Without transparency, commercial tenants cannot verify whether they are absorbing residential or hospitality expenses.
