Should I convert a duplex in South Pasadena back to a SFR?

[Simon Qu]

Hi All,

Hope you all can give me some advice.  I recently purchase a duplex in South Pasadena but the zoning is Single Family Resident so the city has no issue with me converting back the unit.

The unit is currently under the grandfather plan which means the building is legally a SFR but not conforming to the currentt laws so I can continue to let it be a duplex or change it to a SFR.

The property needs substantial amount of work estimated around 100k and is 1600 square feet.  I am looking to move my family into the duplex after rehab so comments or suggestions is appreciated. 

Thanks
