Building a 7 sf (6 sf conditioned + sf unconditioned) addition onto the existing (after removing roughly 1 sf of existing). New proposed sf would be 1976 sf (1846 sf conditioned + 1 sf unconditioned). New construction will include a master bedroom and bathroom, family room, dining and laundry. Roughly 1 sf of the new construction will be slab on grade and the rest will be crawlspace.... Sides min 5... Rear min 20... No new 2nd kitchen.
