This act creates a new "American dream home" program by adding new statutory sections to multiple RCW chapters. It authorizes permits through December 31, 2036, for owner-occupied single-family homes of 1,500 square feet or less reserved for low-income households, requires seven-year covenants keeping resale affordable to low-income buyers, and requires homes to meet local building codes and specified stormwater limits tied to the Department of Ecology’s construction stormwater general permit. Cities and counties must limit cumulative permitting fees for each American dream home to $1,250, may site such homes outside urban growth areas, must report permit counts annually to an unspecified "department" through March 1, 2036, and may receive distributions intended to offset certain impact and permitting costs. The act creates several state tax and fiscal changes: it directs that the state portion of certain taxes collected under chapters 82.08 and 82.12 RCW be used to offset specified impact fees and be distributed to cities and counties (distribution provisions expire July 1, 2036), it establishes a builder tax credit equal to 4% of the gross selling price of qualifying homes against taxes under chapter 82.04 RCW (earned for sales through June 30, 2036, claimable until June 30, 2037, with the section expiring July 1, 2038), and it provides a seven-year property tax exemption for the assessed value of qualifying homes beginning the January 1 after construction completion (claims filed with county assessors on department-provided forms). The legislature expresses intent to appropriate funds to the Department of Commerce for down payment assistance and to reimburse local governments for forgone revenue. This is a programmatic and procedural law with tax credits, tax distribution instructions, a property tax exemption, local permitting and reporting requirements, and time-limited expirations; it does not create a criminal penalty but changes tax and administrative procedures. The act takes effect July 1, 2026 and applies to taxes levied for collection in 2026 and thereafter. Several administrative details are not specified in the provided text: which state "department" is responsible for reporting, remittances, forms, and rulemaking is not identified; the relationship between the fee-offset requirement and section 4 (which establishes the property tax exemption) is unclear; the detailed mechanism and fiscal effects for state tax distributions and offsets are not fully described; and the source or method for determining area median or median family income for eligibility is not specified.

If enacted, this creates a time-limited program to spur small, owner-occupied single-family homes for low-income households by lowering several costs and providing tax incentives: local permitting fees for each qualifying home would be capped at $1,250, impact fees could be offset by a state share of certain sales taxes distributed to cities/counties, builders could claim a nonrefundable 4% tax credit on the gross selling price, and qualifying homes would be exempt from property tax for seven years. Low-income buyers would likely face lower purchase and early ownership costs and could be eligible for down payment assistance by legislative intent; builders would gain a predictable tax break but must meet program rules and reporting; cities and counties would have to approve permits, limit fees, follow siting and stormwater limits, and file annual permit counts while potentially seeing reduced local revenue offset by state distributions and possible reimbursements. The provisions are time-limited (permit requests allowed through Dec. 31, 2036; various tax and credit sections expire in 2036–2038; act effective July 1, 2026) and create new administrative duties for an unspecified “department” to determine eligibility, remit distributions, provide forms, and compile reports. Important implementation details are unclear from the text provided: which state department is responsible, how section 4’s described funds offset permitting fees (section 4 itself sets a tax exemption), the exact mechanism and fiscal impact for the sales-tax-derived distributions, and how local median income figures will be set.
