The Marysville City Council has approved changes that will make it easier to build and permit mother-in-law housing units.

“Recent code modifications give more flexibility to property owners who are looking to build an ADU (accessory dwelling unit) on their property,” said Haylie Miller, Marysville’s Community Development Director.

The newly updated code allows for larger accessory dwelling units, which are secondary homes or apartments that share the building lot of a larger, primary home. In Marysville, these units can now be up to 50% of the size of the home. ADU permit fees were also reduced. Additional parking is no longer required in locations near major transit stops.

The property owner is still required to live in the unit or the primary home. Marysville’s regulatory changes follow state actions to create more affordable housing options in Washington.

Depending on your project, a simple building permit in Marysville could be issued the same day. The most eligible permit types include single-family home additions, alterations to a home’s interior, decks (new or alterations), garages, pole buildings, and reuse of an existing building for small business. 

The Permit Center, located at the Community Development office at 80 Columbia Avenue, is open from 7:30 a.m. to 4 p.m. Schedule an appointment for coordinated customer service by calling 360-363-8100. Permit information and applications are also available on the Marysville website.
