I received a response to my last question regarding retail/office space measuring. The response was clear except that the term "building line" that was used in the response was vague. Building line as decribed in architecture and construction is the line on a property beyond which no building is allowed - often used as "building set-back line." The response stated "under the BOMA 2010 Office Standard, occupants of retail space with exterior access to Public Pedestrian Thoroughfares, rentable square footage should be measured to the building line." (Quotes - mine). Accordingly, in this case, would retail rentable space include columns and covered walk areas/arcades outside the storefront up to the building line?

In terms of the related "building line" definition in architecture/construction, the BOMA distiction becomes very confusing. Any help here? Yes, I am on a learning curve - so any consideration for my edification would be appreciated.
