Washington's coastal and inland climates present specific challenges for ADU construction, requiring robust waterproofing systems, high-performance insulation to mitigate heat loss during colder months, and the use of materials resistant to moisture and decay, such as engineered lumber and advanced composite sidings. Adherence to the Washington State Energy Code (WSEC) is paramount, dictating stringent requirements for thermal envelope performance and HVAC efficiency. The prevalent housing stock, often featuring mid-century homes with established landscaping, offers considerable potential for integrating ADUs while respecting existing neighborhood character.
