Learn how DADU real estate law can help homeowners in dense urban areas like Seattle, Tacoma, and Everett recognize highest and best use of their property.

The zone around a city where denser development is encouraged and services (roads, water, sewer) already reach. If your property sits inside the UGA, HB-1337’s biggest benefits apply to you.

Many people hear the word “condominium” and think of a type of building. In reality, a condominium is a form of ownership, not a type of structure.

Before HB-1337, homeowners who wanted to create separate ownership for multiple homes on a single property typically had to go through a formal subdivision process. That process could be expensive, time-consuming, and subject to extensive local/municipal review.

HB-1337 introduced a simpler alternative. Instead of subdividing the land, property owners can use condominiumization to create separate ownership interests for the homes on the property. This allows a main house and DADUs to be owned and sold separately without going through the traditional subdivision process.

The key difference is that condominiumization creates separate ownership rights rather than new land lots. In practice, however, it can achieve a very similar outcome: multiple independently owned homes on what was originally a single residential property.

In simple terms, HB-1337 lets you achieve many of the benefits of a subdivision—separate ownership and sale of individual homes—without having to formally subdivide the property.
