I have a developer that has asked about changing the definition of a "dwelling unit" in our land use code. He would like to make the unit based off the size of an apartment. His argument is that one of the primary goals for zoning is to control density and there is a difference between density when you compare a studio apartment to a 2 or 3 bedroom apartment. He is suggesting that we define the units based off the number of bedrooms in that apartment. For example a Studio or 1 bedroom may be considered .33 unit, a 2 bedroom .66 units, a 3 bedroom 1 unit, etc. Right now our ordinances for a multifamily property just states how many units per acre are allowed but there is nothing in the definition for a "dwelling unit" that says how big a unit is. This would allow the developer to have more apartments if they were smaller apartments as opposed to larger apartments. Is there anyone out there that has seen it done this way? or are there any thoughts on advantages or disadvantages to doing it this way?
