10D-023 Accessory Apt Cellar/Basement39 Florence St Accessory Apartment
Gross floor area 899 sq. ft.; cellar is also 899 sq. ft. area.
The plans do not show any escape openings in the cellar. Emergency escape openings
are required in any occupied cellar or basement.
It seems that this would be allowed under 350-10.10 because the space below grade would be defined as a cellar. We would restrict the
cellar to utilities, etc and not useable as habitable space.
350-10.10 ACCESSORY APARTMENTS
(B) (5): The gross floor area of an accessory apartment (including any additions) shall
not be greater than 900 square feet.
