The city of Bremerton in the state of Washington recently eased regulations for the development of Accessory Dwelling Units to increase housing production and affordability, reports Doug Trumm.

"Existing rules allowed backyard cottages or attached ADUs to be up to 60% of the size of the primary residence," writes Trumm. "New rules allow ADUs up to 1,000 square feet in size or 60% of primary residence, whichever is larger. That means smaller lots can still support a reasonably sized ADU. Production was anemic under previous rules."

Christon Volser provided coverage of the city's new ADU laws at the time of the City Council approval in December 2020.

"Wednesday’s ordinance removed parts of city code that required residents to provide a parking space when building an ADU and simplified many of the design standards meant to ensure ADUs matched the surrounding neighborhood," writes Volsar. "The new rules also increase the maximum size of an ADU and waived a requirement that forced owners to live on-site year-round."

Trumm includes a soundbite from Bremerton Mayor Greg Wheeler, a "big backer" of the legislation, making the case for ADUs as a tool for housing affordability.

"We are faced with a shortage of residences in our City, and we can’t wait years for new homes and apartments to come online to address the growing demand. Even during the pandemic, we must respond to address this crisis. ADUs are one part of the solution that we can use to scale up now and make housing more available across Bremerton," said Wheeler in a statement.

As noted by Volser, the new law stopped short of implementing the staff recommendation to allow a second ADU per residential lot.
