To maintain enough clearance between cabinets for people to work and pass each other, draw all doors and drawers in the open position in the design phase. While the he HUD Minimum Property Standards stipulate a minimum clearance between cabinets of 40 in. for one person, 42 in. is a more generous target. For two, the minimum is 48 in. 60 in. is a more generous allowance. Anything over 60 in. just means extra walking between one counter and the next, reducing efficiency.
