correct know, i do not have anyone here to -- >> notno, i do not have anyone here to do that. gregg's section -- >> section 12 of 5.1 was put into -- 1,201.5 -- 1,205.1 was put into the code has adopted. it was part of the rezoning in much of the city. let's take their rezoning of the east neighborhoods. it was a limited density. for projects that are info project and are only light and have a requirement for 40% in 10% of the units and in some cases, 3-bedroom units, they need to bar light from next door in order to meet the code. -- they need to borrow light from next door in order to meet the code. the 2010 building code does allow for light and air to be borrowed from the room next door. i believe that it will greatly affect projects moving forward as far as density goes. if we have another agenda item afterwards, which is the green building, for high-density housing, we need the ability to be able to borrow light from the room next door to create bedrooms. i would ask you to eliminate this from the san francisco building code and the back to the california building code.
