To complement your workday, we strive to provide a mix of convenient services, programs, and amenities that foster a thriving, connected community at your building, one that reflects the unique personality of your company and colleagues, as well as the surrounding neighborhood. We are pleased to provide you and your team with onsite services and amenities, which you can access and utilize as follows.




An access-controlled bicycle storage room is located in the parking garage on the 1B level. There is no charge for use of the bike racks, but bicycle parking is first-come, first-served. 

All tenants using the bicycle room can request access to be added to their Kastle access from the Property Management Office.


Bicyclists are directed to enter and exit the garage through the parking ramp located on 18th Street. Please use caution and walk all bikes up and down the garage ramp.

As a reminder, bicycles are not allowed into tenant spaces or in passenger elevators. 


At Columbia, we rate our buildings through WiredScore, an international digital connectivity rating platform for commercial real estate that champions cutting-edge technology in office buildings. Certification through the WiredScore program provides you with the reassurance that your building can meet your team’s technology needs and gives you an easy resource to find the technology providers and points of access available at your building. 

1800 M Street is Wired Certified Gold!  

Wired Certified Gold means a building provides you with access to multiple high-quality internet service providers and a variety of cabling types, including fiber. The infrastructure measures in place ensure connectivity sources are protected, redundant, and prepared to meet your current and future connectivity needs. 

On the Tenant Resources page of the website, you will find an overview fact sheet of the connectivity and digital infrastructure features of the building. Available carriers are listed in case you are looking for a new or secondary internet connection. 

Because your building is WiredScore Certified, you also have access to WiredScore Connect. This complimentary concierge service is designed to help any tenant get quickly and easily set up with the internet service providers in their building, and compare service and pricing available to find the best alignment with your company’s specific needs. 

For direct assistance from WiredScore’s highly knowledgeable team, call 646.869.6000 or email, or visit to learn more.

Many other services may be brought into the building via one of the carriers with a physical presence. Tenants seeking additional or alternative services should contact the desired provider and notify the Property Management Office.
