A key tool to keep rents and home prices under control in cities big and small is to change rules that prevent all but the largest, most expensive homes. Giving owners more freedom to create accessory dwelling units—granny flats, laneway houses, mother-in-law apartments—in centrally-located neighborhoods gives flexibility for all kinds of households and all stages of life. An ADU might make it possible to stay in your home and age in community. You might be able to help out a family member. Or maybe you could use some income from a small rental. On the flip side, you might be a renter who cuts costs and commute time by finding a modest, affordable ADU home near work, school, or good transit.
An ADU opportunity in Washington state
Washington state legislators are sponsoring a bill (HB 1797/SB 5812) that could unleash the affordability and sustainability benefits of ADUs across the state. In cities of 2,500 people or more, and within urban growth areas, the bill would permit two ADUs wherever there is a single, detached house, duplex, triplex, or townhome. It would eliminate off-street parking, owner-occupancy, and minimum lot size requirements. It would cap impact fees, reduce burdensome utility connection fees and capacity charges, and give more flexibility in design and placement. In short, it would be easier and cheaper to add this kind of home to the mix in most neighborhoods.
