Business Rates

For most commercial building owners, you will be assessed an annual charge on the property tax statement for the building. How and whether these charges are passed on to building tenants is determined by the lease between the building owner and the tenant. The District has no opinion or recommendation on how or whether the District's fees are passed on to building tenants.

To determine in which group you property is, please contact us.
