Street frontage

Dominic Tremblay

I think there is a discrepancy in the BOMA STANDARD for OFFICE, 1996.

On page 14, the FLOOR USABLE AREA is shown as following the building line for all the left side, meaning that the BUILDING COMMON AREA of the entrance on this side would follow the BUILDING LINE too.

On page 22, the same BUILDING COMMON AREA is shown as following the dominant portion of the wall.

What is the rule to follow? Considering STREET FRONTAGE, should it apply to only STORE and OFFICE area? All areas? What about FLOOR COMMON AREAS?

Thank you for your answer

Hi Dominic,

We are aware of this discrepancy. On Page 22, "Measuring Building Common Area" it says "Building Common Areas are measured like an Office Area or Store Area...". Therefore, I believe the illustration on page 14 is correct.

Thank you for your answer. I am a little mixed up... On the question "Does Street Frontage apply to Building Common Area?" asked on this forum on December 2013, you answered "Building Common Area should be measured to the dominant portion of the inside finished surface regardless of street frontage or not. Street frontage does not apply to Building Common Area as per page 22 of the standard."

Does that mean that we can interpret and do as we like?

What about Floor Common Areas... Are these like Building Common Areas?

Thanks David

Hi Dominic,

The problem with having conflicting information in the standard is that you get conflicting responses! Now that I've taken a second look at this issue, I believe the wording in the standard is more critical than the illustrations. Again, page 22 says that "Building Common Areas are measured like an Office Area or Store Area..."

The Store Area condition does not apply to Floor Common Area. Floor Common Area is not like Building Common Area. Building Common Area is measured like a tenant area and is considered part of the Usable Area, whereas, Floor Common Area is the remainder of Floor Rentable Area and Floor Usable Area. Floor Common Area is proportionately allocated to tenant areas and building common areas.
