Subdivide and Build a Duplex North Oakland CA?

[Stefan Isaksen]

I have a triplex in North Oakland on a large city lot in an area that has seen dramatic appreciation in the 10 years.  An adjoining property with similar footprint, lot size etc. sub-divided and built a single family home behind a duplex.  They sold the new 1,700 sq ft. home for 1.1 Million a year ago which caught my attention and made me want to consider my options.  I'd love to hear some ideas about the pluses and minuses of doing a project.  Some options that I'm considering and seem feasible after a bit of investigation at the city are-

1-Subdivide and sell the lot (with or without entitlements)

2-Create 2 new micro-lots and build 2 townhouse style homes to sell

3- Subdivide and build a duplex to hold (no rent control on new construction = big plus in Oakland)

4-Subdivide and build a single family home to sell

Thanks in advance for any ideas!
