San Jose R-M Zoning restrictions

[Kay Kumar]

I was wondering how many units I can build in R-M neighborhood in San Jose. The lot is only 4500. Currently ours is a single family home. Can I get a permit to build 3 units (each with 1000 sq st approx) and rent  them. What is the FAR for this type of zoning? Any restrictions that I need to be aware ?

Thanks,

-Kay.
