Building Services

To request routine services, please contact the Management Office at or submit to the Tenant Work Order Portal. Requests that are more detailed, such as moving, painting and lock changes should be submitted in writing via e-mail to ensure that the work is completed per tenant's direction. When requesting services, we require that it come from an authorized tenant contact, particularly those that incur costs on your company's behalf in order to simplify monthly invoicing.
