This is a condo unit
Zoning applies to the whole building/lot, not individual units. Any changes would require the condo association or building owner to act. The analysis below covers the entire property.
Your existing property can stay exactly as it is.
This proposal changes what could be built here in the future. It does not require you to change, sell, or alter your property in any way.
