We have a substantial turn of the century warehouse area which is on the verge of becoming a mixed use district. Property owners have expressed concern in the area about residential unit density. Although they would like to create a good number of units in their warehouse buildings, they want to prevent single-room occupancy type uses. They are proposing a minimum unit size of around 500-600 square feet.
I'm interested if other communities have similar regulations. I'm most interested in communities who have these minimum units sizes in urban mixed-used areas.
My warehouse area is predominately 3-6 story turn-of-the-century brick warehouses. Nearly 100% lot coverage.
Edit: our building codes will allow as little as 300 sq ft per unit.
