Convert Duplex to Triplex in Oakland, CA

[Calvin Kwan]

Hi Guys, My duplex in Oakland is zoned RM-2. I would love to convert my duplex to a triplex if possible. I'm currently renovating my rear unit and it has the perfect layout to split into 2 units by adding a wall and an additional front door. To do this legally, I know plans need to be drawn and submitted to the Planning Board. Can I submit these plans or does it need to be done by my contractor? Are inspections needed before and after the work? Has anyone had any experience with this process? According to the Planning Board, the intent of the RM-2 Zone is to create, maintain, and enhance residential areas characterized by a mix of single family homes, duplexes, townhouses, small multi-unit buildings, and neighborhood businesses where appropriate. I'm assuming by definition I am zoned to convert to a triplex? Thanks for all your help! Calvin

Hey Calvin, 

A few things to consider. 

How big is the lot your property is on? You need to have a property with a certain size lot in order to add units. Check out this table: https://www.municode.com/library/ca/oakland/codes/...

This is what you're looking for: https://www.screencast.com/t/Xkyp3OZWk

I Oakland, for a building with 3 units or more you need to have a lot sized at 7,500 sq ft.  --- From the zoning code it says, an RM-2 zoned lot can have "1 unit per 2,500 sf. of lot area"

If you don't meet that lot size requirement you'll need to make a request for a variance, then post notice about the desired change in front of the building. From there if no one objects, the city will give you a conditional use permit. That's the process as I understand it. I've got plenty to learn here though.

 

I'm considering doing this for my duplex as well. My lot size is 7,467 sq ft --- just under that 7,500 sq ft mark. I'm hoping that when I'm ready I can get the conditional use permit. It's either that, or try to buy 33 sq feet of land from one of my neihbors. haha...
