WASHINGTON, DC–Balconies, covered galleries and finished rooftop terraces that are for the exclusive use by a tenant may now be included in the rentable square footage calculation. That is one of the updated standards the Building Owners and Managers Association has made in its latest update to its floor measurement standard for office buildings, BOMA 2017 For Office Buildings: Standard Methods of Measurement. BOMA released the update this week. The last time this guide was published was in 2010, and a lot has changed since then — including the now very popular amenity of an exclusive rooftop terrace.
