ADUs, or Accessory Dwelling Units, and DADUs, which are Detached Accessory Dwelling Units, are becoming more common thanks to a state law (House Bill 1337) that changed some zoning restrictions in order to create more housing options.
Now, folks are creating ADU/DADUs for their aging parents, young adult children, for a quiet work (near) home space, and as a retirement plan — one builder shared that one example was homeowners who wanted to downsize and moved into the DADU, and their kids and grandkids moved into their much larger home.
Here are some things to know when considering an ADU/DADU.
1. An ADU/DADU contains a kitchen, bathroom, and sleeping area. It is located within (think converted basement), or on the same land as the main home.
2. State laws may vary depending on the city. Make sure to check that your plans meet the criteria — such as max height, setback rules, and more.
3. ADUs/DADUs must meet all safety criteria and building codes and be permitted just like other homes.
4. You might be able to rent your DADU/ADU for an additional revenue stream.
5. You aren’t required to tell your neighbors you are considering building an ADU/DADU, but remember, common courtesy goes a long way. It might be nice to share your plans with those who live in close proximity.
6. Some areas offer tax incentives — such as property tax exemptions and exemptions for seniors or disabled homeowners.
7. Before building, you’ll need to secure construction, electrical, plumbing, and sewer permits with local city departments — this process can often take a few months. To minimize waiting, pre-approved ADU/DADU plans are often available.
8. In some jurisdictions, owners are not required to live on-site of their built ADU/DADUs.
