worth building duplex on empty lot in modesto?

[Thomas Kwan]

hi there

We are looking at an empty lot in modesto. it is currently R-2 zoned and it is about 28,000 sq ft. Last time I checked with the city, they said we can only build a duplex on it cos the site has no public sewer.

Anyone has experience in building duplex or putting a manufactured home in an empty lot in around Modesto? I want to find out how much would it cost to build a duplex and want to see if it is worthy to do.

thanks in advance
