I have 2 garages on my multi family property, I was wonder if anyone knows what the process is for permits and sewer costs? It already has power and I can do majority of the work, wonder what’s costs have others come across this conversion?

There are always exceptions, but as I understand the regs @Matt J. is correct. The ADU's reg's mentioned by other posters are for Single Family zoned properties, not Multifamily (lowrise) zoned. In Seattle this means a 650 sq ft DADU, but no additional ADU's (unless the zoning permits more units, but either way that would be adding additional units, not a ADU, to a multifamily.)

95% of garage conversions are done without permits and are not legal, especially if the property is multifamily.

    check your local city requirements for ADU's. should be available via online websites. If you can't find it i have a contact in tacoma who does lots of work around ADUs.

    @Gerardo Ali

    Raise the ADU size maximum: Tacoma restricts ADU size to 1,000 square feet, or 15 percent of the lot size, or 85 percent of the main house size, whichever is smallest. ... Seattle currently allows 1,000 square feet for ADUs that are part of the main house, and has proposed raising the limit for DADUs to 1,000 square feet.

    @Gerardo Ali You'll want to confirm but I'm 99% sure you're not allowed to add an ADU to an existing MF property in Tacoma.

    When they loosened their guidelines recently I read all the changes and am almost certain I saw this restriction. Google Tacoma WA ADU and I'm sure you'll find it.

    Good luck.
