Converting SFR into duplex in Orange County

[Joao Pedro Sudati Arduin]

Good evening! Any suggestion of books or posts where I could obtain knowledge needed to evaluate feasibility of converting single family residences into duplex? Specifically talking about Orange County. Thanks!

What are you looking to do on the SFR? An actual ADU or SFR to duplex? You will have to get entitlements changed (zoning changed), unless you are already on a 2-4 family zoning lot, or within an area that has that around it. You will have to go through that process with the city. May take you 2-4 months or 6-12 months to get that approved then starts the process of permits for building approval (same timeline), and then you will start build which will be about 6-8 months or less depending on size etc.

The hardest thing will be zoning regs for the city and change, and Orange County cities will be harder than lets say a city way out on the east end of San Bernardino County.
