Rezoning a SFH (zoned B-4) to a Triplex in Aurora, CO

[Pierce Lovesee]

Hey guys, I wanted to see if anyone had experience rezoning a single family home (zoned B-4) in the Denver area, specifically Aurora in this case, to a triplex. I found a deal that the owner is currently cash flowing on the property with it being zoned as a SFH but used as a triplex. So my two main questions are: 1. What are the costs and time investments on getting a property rezoned in this area? 2. What would be the benefit of rezoning the property? Is it legal to continue operating the property under B-4 zoning with tenants? Any advice would be greatly appreciated. Thanks for the help!
