During a recent government meeting, city officials discussed significant updates to housing policies aimed at addressing the growing need for affordable housing and diversifying housing options in Sammamish. Key topics included the introduction of cottage housing, accessory dwelling units (ADUs), and the implications of new state legislation.

The meeting highlighted the challenges of implementing cottage housing codes, emphasizing the need for tailored approaches that consider the unique characteristics of different neighborhoods. Officials expressed a desire to incorporate sustainable practices into new housing developments, such as green roofs and stormwater management systems, to promote environmental efficiency.

A major focus was on accessory dwelling units, with proposed changes to zoning regulations allowing for two ADUs on any lot, increasing the maximum building height from 18 to 24 feet to comply with state law. The discussion also touched on the elimination of owner-occupancy requirements for ADUs unless they are intended for short-term rentals, aiming to streamline the process for homeowners.

The meeting also addressed the concept of unit lot division, which would facilitate ownership opportunities by allowing smaller parcels to be created for housing development. This approach aims to encourage homeownership in a market that has seen a shift towards rental properties.

Another significant topic was the proposed mandatory housing affordability requirement, which would require a percentage of new housing units to be designated as affordable. This initiative is part of a broader strategy to leverage the upzoning allowed by recent state legislation (HB 1110) that mandates cities to accommodate middle housing types. The city is considering a 10% affordability threshold for new developments, which would require developers to either include affordable units or pay a fee in lieu.

Concerns were raised about the potential impact of these policies on existing neighborhoods, particularly regarding the integration of new housing types into established areas. Some officials expressed apprehension that the introduction of multiple housing units could lead to a homogenization of neighborhoods, rather than fostering diversity.

The meeting concluded with discussions on the need for careful planning and community engagement as the city moves forward with these housing initiatives. Officials acknowledged the importance of balancing development with the preservation of neighborhood character and the need for affordable housing solutions. Further workshops and discussions are planned to refine these proposals and address community concerns.
