CP 00 18: Condominium Commercial Unit-Owners Coverage Form Explained

CP 00 18 is the ISO commercial property coverage form for a business or professional firm that owns a commercial condominium unit. It does not provide a separate Building coverage category. Instead, it covers qualifying property under Your Business Personal Property, subject to the selected causes of loss, and coordinates with insurance carried by the condominium association. It is not the Business Income (Without Extra Expense) form, which is CP 00 32.

The condominium documents allocate property between the unit owner and association. Compare that allocation with the actual covered-property wording; a bylaws obligation is not itself an insurance grant.

What property can CP 00 18 cover?

CP 00 18 covers qualifying property under Your Business Personal Property when a limit appears in the declarations. That category can include furniture, machinery and equipment, stock, other business property, and leased personal property the unit owner must insure. It can also include owned fixtures, improvements, and alterations that become part of the building. The form does not provide a separate Building coverage category. Personal Property of Others is a separate category, with its own requirements and limit.^[3]

The form follows much of the structure of CP 00 10 but changes provisions to fit condominium ownership. Insurance industry analysis identifies CP 00 18 10 12 as the dedicated form for business or professional firms that own commercial condominium units.^[1] The selected causes of loss form, such as CP 10 30, determines which causes of direct physical loss or damage are covered.

How does it coordinate with the association policy?

CP 00 18 recognizes that two policies may touch the same building element. Property that the condominium association must insure under its agreement or bylaws is not covered property under the unit-owner form. If association insurance nevertheless covers the same property that qualifies under CP 00 18, the unit-owner coverage is excess and does not contribute with the association insurance.

Do not settle the boundary only by asking who paid for an improvement. A wall, built-in cabinet, HVAC component, sign, or floor finish may be allocated differently by the condominium documents and state law. Optional CP 04 18 can add forms of loss assessment and miscellaneous real property coverage when attached.^[1]

What does CP 00 18 not solve by itself?

The base form does not guarantee that every unit loss is covered. Flood, earthquake, equipment breakdown, ordinance costs, and water backup depend on the causes of loss form and endorsements. The declarations control limits, deductibles, premises, and options.

CP 00 18 is not business income insurance. A covered fire can stop operations, but lost revenue and continuing expenses require separate coverage. The commercial property forms list distinguishes CP 00 18 from CP 00 30 and CP 00 32.^[2]

What should a commercial condo owner review?

Start with the condominium declaration, bylaws, association policy, unit-owner policy, and any occupant lease. List improvements, fixtures, equipment, stock, and property of others, then identify which policy is meant to insure each item. Confirm that names and addresses match the ownership records.

Ask for the association's current property evidence and deductible. Review loss assessment exposure because the association may assess owners after damage to common property. Value improvements at current replacement cost and update limits after renovations or equipment purchases.
