We own a duplex in NE Portland. We are planning to convert the unfinished basement into a third unit. Our lot is zoned R2.5. Our understanding is that the Residential Infill Project (RIP) will make this easier to accomplish; however, I am still unclear how we will proceed. My understandings/issues are listed below:
1. We can now add an ADU, but the unit must be attached.
2. We can legally build out the basement making the building a triplex. Still, the new unit will be subject to the commercial code ($) with additional construction and safety requirements. Will this requirement be updated with the implementation of the RIP? I.e., will the new unit have to comply with the residential building code?
3. When will the different provisions go into effect? Is implementation being delayed to allow for potential legal challenges?
Any other information is appreciated. Our Contractor is ready to break ground, but we are waiting to hear back from the City of Portland.
My understanding is that more than two (3+) units make you subject to commercial code no matter what. I don't have confirmation of this, but it's hard to imagine life safety measures taking a backseat as density increases. Firewalls, sprinklers, and other such upgrades often make these types of additions untenable. Curious how your experience goes.
I haven't heard of an exact date, but I've heard it will be in 2021 when the policy is officially implemented.
There is a lot of work associated going from 2 to 3 units. I think that when it does pass you will be able to have a duplex + 2 adus which keep you out of commercial code. Adu will have to be under 800 sq ft.
I’m in the process of converting a 2 to 3 units and the previous comments are correct. Fire sprinklers, upgrades to water lines. The sdc fees and permits were 40k just on their own. I also think there is still a waiver on the adu sdc fees which says you won’t rent it out as a short term rental.
