Alright, let's talk Junior ADUs, or JADUs. I get a lot of questions about these, especially from folks here in Beaverton who want to add some flexibility or value to their property without going all-in on a detached ADU. They're a bit different, and the rules can be a little confusing, so I'm going to break down the most common things I hear about them.
What exactly is a Junior ADU, and how is it different from a regular ADU?
Okay, so a Junior ADU is basically a smaller, self-contained living unit you create inside an existing single-family home. Imagine turning part of your house—maybe a spare bedroom suite, a den, or even a garage that's already attached to the main house—into a separate apartment. The big difference from a regular ADU comes down to size and some specific requirements. JADUs are generally smaller, usually topping out at 500 square feet. They have to fit within your home's existing footprint, and they share a wall with the main living space. They also usually need to share a bathroom or at least a plumbing connection with the main house, though they'll have their own entrance and a small kitchen or kitchenette. A regular ADU, on the other hand, can be detached, attached, or converted from a garage; it generally comes with a full kitchen and bathroom, and it can be larger.
Can I build a JADU on any property in Beaverton?
Not quite 'any' property, but most single-family zoned lots in Beaverton are eligible. The main thing is you need to have an existing single-family home on the lot already. You can't just build a JADU on an empty lot, that's not how it works. The property also needs to be zoned for residential use, which covers most of Beaverton. There usually aren't minimum lot size requirements for JADUs like there sometimes are for detached ADUs, since you're working within your existing structure. But always double-check your specific property's zoning with the City of Beaverton planning department. They're the folks who have the final say on what's allowed where.
What are the basic requirements for a JADU in Beaverton?
The rules can shift a little, but generally, here's what you're looking at for a JADU in Beaverton:
- Size: It can't be more than 500 square feet. That's a pretty firm limit.
- Location: It has to be entirely inside the existing walls of your main home. You can't add an extension just for the JADU.
- Entrance: It needs its own separate exterior entrance. This is crucial for privacy and independence, don't you think?
- Kitchenette: You'll need a small kitchen area. This usually means a sink, a cooking appliance (like a two-burner cooktop or microwave, not necessarily a full range), and a small refrigerator.
- Bathroom: This is where it gets a little tricky. The JADU must connect internally to the main dwelling, and it can either share a bathroom with the main house or have its own. The Beaverton code often allows for shared plumbing facilities.
- Owner-Occupancy: This is a big one. Either the main house or the JADU must be lived in by the property owner. You can't rent out both units unless you're living in one of them. This is a common rule for JADUs to make sure they're primarily for the owner's benefit or for family use.
- Parking: Often, you won't need extra parking for a JADU, which is a nice break compared to some ADU requirements.
These are the general strokes. When you're serious, you'll want to get the specific, current code from the City of Beaverton planning department or a good contractor like Coastal ADU who stays on top of these things.
Do I need to add extra parking for a JADU?
Good news here for most folks: typically, no, you don't need to add extra parking for a JADU in Beaverton. This is one of the advantages compared to some full ADUs, where parking can sometimes be a hurdle. Since JADUs are smaller and often meant for family use or as a more compact rental, the city generally doesn't require an additional parking space. This makes them a lot easier to integrate into properties, especially in older Beaverton neighborhoods where driveways might be tight or street parking is already competitive.
What's the typical cost range for building a JADU in Beaverton?
This is where it gets a bit like asking 'how long is a piece of string?' It really depends on what you're starting with and what you want to end up with. But generally, because you're working inside an existing structure and usually not adding a lot of square footage, JADUs tend to be less expensive than building a brand-new detached ADU. You're looking at costs for things like:
- Demolition (if you're taking down existing walls or features)
- Framing for new walls and doors
- Plumbing for the kitchenette and potentially a new bathroom
- Electrical work for new outlets, lighting, and possibly a sub-panel
- Finishes like flooring, paint, cabinets, and appliances
- Permits and architectural/design fees
For a basic JADU conversion, you might be looking at anywhere from $60,000 to $120,000+. If you're doing a high-end finish or running into unexpected structural issues, it could go higher. The best way to get a real number is to get a few bids from local contractors after you have a clear idea of your scope. Don't forget that older homes, especially those built before the 1980s, might uncover some surprises like asbestos or lead paint during demolition, which can add to the cost.
Can I rent out my JADU, or is it just for family?
Yes, you can absolutely rent out your JADU, but there's that big owner-occupancy rule I mentioned earlier. Either you, the property owner, must live in the main house, or you must live in the JADU. You can't rent out both units at the same time. This means if you're planning to move out and rent your main house, you wouldn't be able to rent the JADU to a separate tenant simultaneously. It's a key regulation to keep in mind when you're thinking about your long-term plans for the property and how you want to use the JADU.
How long does the JADU permitting process usually take in Beaverton?
The permitting process in Beaverton, like anywhere, can feel like it takes a while. It's not usually as complex as a full ADU, but it's still a process. Once you have your plans drawn up and submitted, you're looking at several weeks, sometimes a few months, for plan review. This depends on how busy the city's planning and building departments are, and how complete and accurate your initial submission is. If they need revisions, that adds time, naturally. After the plans are approved, you get your permits, and then construction can start. The actual construction phase for a JADU, since it's typically an interior conversion, might take anywhere from 2 to 4 months, depending on the scope and any unforeseen issues. My advice? Start early, be patient, and make sure your plans are solid from the get-go to avoid unnecessary delays.
What are the biggest benefits of adding a JADU to my home?
There are some really solid upsides to a JADU, especially for folks here in Beaverton. First off, it's a fantastic way to add some flexible living space. Maybe you've got an aging parent who needs to be close but still wants their independence, or a college kid who's back home but needs their own space. It's perfect for that. Second, it can be a great income generator. Even with the owner-occupancy rule, renting out a JADU can provide a steady stream of income to help with your mortgage or other expenses. Third, it generally increases your property value. Having that extra, legal, self-contained unit makes your home more attractive to future buyers. Finally, it's often a more affordable and less disruptive option than building a brand-new detached ADU, since you're working within your existing footprint. It's a smart way to make your home work harder for you.
