This bill prevents cities, code cities, and counties in Washington from banning or mandating specific exterior cladding materials—as long as the materials meet the state building code—while preserving the ability of private homeowners' associations and plat communities to set their own cladding rules.

  • Cities, code cities, and counties are prohibited from requiring or banning exterior cladding materials that meet the state building code.
  • The law defines 'exterior cladding' as any nonload-bearing material attached to the outside of a building (e.g., siding, stucco, brick veneer).
  • The restriction does not apply to private rules set by homeowners' associations (HOAs) or plat communities, meaning those groups can still impose cladding restrictions.
  • The law applies to all three types of local governments: cities (under chapter 35.21 RCW), code cities (under chapter 35A.21 RCW), and counties (under chapter 36.01 RCW).

Who is affected

  • Local governmentsLocal governments (cities, code cities, and counties) can no longer ban or mandate specific exterior cladding materials as long as the materials meet the state building code.
  • Homeowners in HOA or plat communitiesHomeowners in developments governed by homeowners' associations (HOAs) or plat communities may still face restrictions on cladding materials set by those private groups, since the bill explicitly excludes them from the new rule.
  • Property owners and developersProperty owners and developers can choose any exterior cladding material that meets state building code, without interference from local governments—potentially increasing material choices and reducing local regulatory barriers.
  • Building inspectors and code enforcement officialsState and local building inspectors must ensure cladding materials comply with the state building code, but cannot enforce local bans or mandates on approved materials.
Effective: July 27, 2025Fiscal impact: Minimal fiscal impact expected; local governments may incur minor costs to update ordinances or training to align with the new state standard, but no significant new spending is anticipated.

Pro/Con Analysis

Stronger case for concerns

Potential Benefits (2)
  • Property owners and developers gain flexibility to choose any state-code-compliant cladding material without local bans or mandates, potentially reducing material costs and construction delays—especially beneficial for small contractors and remodelers who operate on thin margins.

    Business & EmploymentRef: Sec. 1(1), Sec. 2(1), Sec. 3(1)
  • The bill standardizes cladding regulations across jurisdictions, reducing regulatory confusion for homeowners and builders who work across city/county lines—particularly helpful in rapidly growing areas like the Puget Sound region.

    HousingRef: Sec. 1(2), Sec. 2(2), Sec. 3(2)
Potential Concerns (3)
  • The bill preserves the ability of private HOAs and plat communities to impose cladding restrictions, which disproportionately affect lower- and middle-income homeowners in HOA-governed developments—many of whom are first-time buyers or retirees—by limiting material choices and potentially increasing maintenance costs if only expensive, high-maintenance materials are permitted by the HOA.

    HousingPeopleRef: Sec. 1(3), Sec. 2(3), Sec. 3(3)
  • Local governments lose authority to regulate exterior cladding materials—even for fire safety, durability, or aesthetic compatibility with historic districts—reducing their ability to respond to local conditions and community preferences, which may indirectly increase long-term public costs (e.g., fire response, infrastructure degradation).

    Local GovernmentPeopleRef: Sec. 1(1), Sec. 2(1), Sec. 3(1)
  • By removing local authority to ban specific cladding materials (e.g., flammable composites, poorly installed EIFS), the bill relies solely on state building code enforcement—whose compliance and inspection capacity varies—and may increase fire or structural failure risks in areas where local governments previously imposed stricter standards.

Who Is Most Affected

Homeowners in HOA or plat communitiesNegative Impact

HOA and plat community residents—especially lower- and middle-income households—may face continued or increased restrictions and costs, as HOAs retain full authority to mandate or ban cladding materials, potentially limiting affordability and material options.

Local governmentsNegative Impact

Local governments lose regulatory flexibility over building exteriors, reducing their ability to address local fire, weather, or historic preservation concerns—though fiscal impact is minimal, their policy autonomy is diminished.

Property owners and developersPositive Impact

Developers and contractors benefit from reduced local barriers to material selection, but the benefit is modest since most cladding choices are already governed by state code; the change mainly simplifies compliance across jurisdictions.

Building inspectors and code enforcement officialsMixed Impact

Building inspectors gain clarity in enforcement (only state code compliance matters), but lose discretion to apply local standards—shifting responsibility fully to state-level oversight, which may strain resources in under-resourced jurisdictions.
