R-3 Zoning in Phoenix

[Tyler Clark]

Hello Friends -

I recently came across a 5-Unit property in Central PHX. The existing livable sq. ft. is 2,800 with the lot size being 19,500 sq ft. It is zoned for R-3 and there seems to be able space to add up to 4 more units.

Based on researching I’m seeing R-3 zoning should have no more than 5 units/acre, but I also see some resources stating it’s 12/acre.

Any experienced Multi-Family investors out there that have any feedback on how many units I may be able to get on the lot and if I can’t add any, what’s the process and cost of re-zoning in your experience?

Thank you!
