On behalf of Columbia Property Trust, we would like to welcome you to 221 Main. We are thrilled that you have chosen our property for your office workplace, and we look forward to a long-lasting and successful relationship. 

This Tenant Handbook has been developed to provide you and your team with a convenient reference guide for commonly asked questions about the operations, procedures, and policies at 221 Main. From time to time, the Property Management Team may issue new or revised material for you to include with this information. 

Many sections in this Handbook reference forms that should be completed by each tenant company and provided to the Property Management Office. For your easy reference, we have included a complete set of these forms at the end of this Handbook. You may also access this Handbook, as well as pertinent electronic forms, digitally by visiting the property website at


Additionally, we have included property emergency procedures in this Handbook for easy reference. Please note that the emergency procedures are of critical importance, so we encourage you to share this information with every employee in your office. 

If you have additional questions or concerns, please feel free to contact the Property Management Office at 415.615.0285. Your tenancy makes our jobs possible, and it is our pleasure to assist you.
