Site, home, and city zoning codes and requirements vary greatly. Not to worry, we’ll do the research you need to make sure that you are building safely and legally on your property. 

Let us worry about regulations on square footage limits, entrance location, and building setbacks, utilities, water or sanitary/storm sewers, all the things that can get in the way of easily adding to your existing property.

In our research, here are some other things we will be looking into:

  • Is your outdoor space approved by the city?
  • How much more square footage can you add?
  • Can your older plumbing handle the additional volume an ADU will bring?
  • Can your older electric service handle the new additional load diverted to the ADU?

Many cities require a building permit on most properties. Do you need one?


Units that require permanent foundation, electrical, plumbing hook-ups. This structure becomes part of your house square footage.


Units that do not need to be permitted are usually classified as such for their size, lack of permanent foundation, or lack of plumbing.  Smaller sheds, workspaces, or garages often qualify. These structures serve as extended space that does not count towards your house square footage. Our smaller Dadu Adus can often be built without permits.

Wood is a natural material that carries its own insulating factor unlike vinyl, fiberglass, or metal windows. It is also repairable and paintable. Windows and doors are made from Solid Clear Vertical Grain Fir with the finest grade available, built locally in Lakewood, Washington. We have specialized in wood windows and doors for over 25 years with our parent company, Bear Wood Windows. We are bringing the same quality and craftmanship to our Dadu Adus that we use on many of Seattle and surrounding area’s historic buildings. The wood that is being used to build the windows and doors are replenished by planting trees each month through National Forest Foundation. We are committed to providing renewable resources as much as possible.
