Why Newcastle is Ideal for ADU Development

Newcastle's incorporation in 1994 means the city was designed with modern zoning standards that accommodate accessory dwelling units more easily than older Eastside communities. The city's commitment to balanced residential and commercial development creates an environment where ADUs contribute positively to neighborhood character while meeting growing housing demands.


• Streamlined permitting process designed for modern development needs

• Lot sizes and setback requirements that often accommodate detached ADUs

• Strong property values supporting ADU investment returns

• Proximity to tech corridor employment centers increasing rental demand

• Tree-lined streets and planned community layout that integrates ADUs naturally


Newcastle's location along I-90 provides excellent access to Seattle and Bellevue employment centers, making ADUs attractive to tech professionals seeking quality housing in a safe, family-friendly environment. With median household income at $162,646, Newcastle residents have the financial capacity to invest in property improvements that enhance long-term value.
