Do I even need a permit for my ADU?
Oh yeah, you absolutely do. This isn't just some shed you're tossing up in the backyard; we're talking about a living space here. Whether you're turning an old garage into a unit, adding an extension onto your house, or building a whole new detached ADU, you'll need permits. The City of Portland wants to make sure everything's safe, up to code, and fits with local zoning rules. Skipping permits might seem like a quick way to save a few bucks now, but it'll cost you way more in fines, demolition orders, or legal headaches down the road. Seriously, you won't be able to sell your house with an unpermitted structure on it, and good luck getting insurance or a loan.
What's the difference between a building permit and a land use review?
Okay, this one trips up a lot of people. A building permit is all about the actual construction. It makes sure your ADU is structurally sound, has proper plumbing, electrical, insulation, fire safety—all those Oregon Residential Specialty Code requirements. This is what my crew at Mighty ADU Company really digs into once the design is finalized.
A land use review, on the other hand, looks at how your ADU fits onto the property and into the neighborhood, according to zoning rules. We're talking things like how far it sits from property lines (setbacks), its maximum height, how much of your lot it covers, and impervious surface limits. Most standard ADUs in Portland's residential zones (like R5 or R2.5) usually don't need a full-blown land use review if they stick to the basic development standards. But if you're pushing the limits on size, height, or trying to build in a sensitive area, you might trigger one. Those reviews can add a significant chunk of time and money to your project, so it's always best to figure out upfront if you'll need one.
How long does it actually take to get an ADU permit in Portland?
Ah, the million-dollar question, isn't it? And the answer is... it really varies. A lot. For a pretty straightforward ADU project with complete, accurate plans, you're generally looking at anywhere from 4 to 8 months. That's from the moment you hit submit on your application until you actually have the permit in hand. This includes the initial review, any corrections, re-submittals, and, finally, approval.
Why such a long wait? Well, the city's Bureau of Development Services (BDS) is busy, and they've got a process. They'll do an initial review, then send you a list of corrections (and trust me, there are *always* corrections). You make those changes and resubmit; they review it again, and so on. If your plans are a mess, incomplete, or you're dealing with tricky site conditions—like a steep slope in Southwest Portland or a property with environmental overlays—it can take even longer. Having a good design team and a contractor who really knows the Portland codes inside and out can definitely help speed things up.
Can I pull the permits myself, or do I need a contractor?
You can absolutely pull the permits yourself as the homeowner, especially if you're planning to do the work yourself. This is called an
