WA HB1299

Cities may not require more than 0.5 parking spaces per residential dwelling unit, and code cities may not require more than 1 space per unit; commercial spaces limited to 1 space per 1,000 square feet

No minimum parking requirements allowed for residences under 1,200 sq ft, commercial spaces under 5,000 sq ft, affordable housing, senior housing, disability housing, child care facilities, alcohol-serving facilities, mixed-use commercial, or buildings undergoing change of use

Cities with population of at least 10,000 in counties exceeding 100 people per square mile may not require off-street parking for multifamily, middle housing, or ADUs within one-half mile of transit service (defined as 4+ times per hour for 12+ hours daily)

ADA-compliant accessible parking spaces are exempt from these restrictions; cities may still adopt maximum parking limits or require frontage improvements for on-street parking

Amends RCW 36.70A.620 by removing previous transit-proximity parking exemptions and replacing them with broader population-based restrictions
