Exciting Progress for the Tiny Home Movement! California & Washington

‍

California and Washington are paving the way for more accessible, affordable housing solutions with new laws supporting tiny home construction. From streamlined ADU regulations in California to Washington's adoption of building codes tailored for tiny homes, it's clear that these states are recognizing the potential of smaller, sustainable living spaces. This is a big step toward addressing housing challenges while embracing innovative solutions.

In recent years, both California and Washington have enacted legislation to facilitate the inclusion of tiny homes as viable housing solutions, addressing affordability and housing shortages. Here's an overview of the current regulations in each state:

California:

• Accessory Dwelling Units (ADUs): California has implemented laws to encourage the construction of ADUs, which include tiny homes. Notably, Senate Bill 9 (SB 9), known as the California Housing Opportunity and More Efficiency (HOME) Act, allows homeowners to build up to two units on single-family zoned properties, effectively enabling the development of tiny homes as additional units.

• Recent Legislative Updates: In 2024, several bills were signed to further support tiny home development:
  • SB 1211: Permits the construction of up to eight detached ADUs on a single lot, expanding the previous limit of two per lot.
  • SB 1164: Provides a property tax exemption for new ADUs for up to 15 years.
  • SB 450: Clarifies the intent of SB 9 and empowers state agencies to enforce its provisions against local governments that attempt to obstruct its implementation.

These measures aim to streamline the approval process and reduce barriers for tiny home construction in California.

Washington:

• Adoption of Appendix Q: Washington State has adopted Appendix Q of the International Residential Code, which provides specific building standards for tiny houses on foundations measuring 400 square feet or less. This adoption facilitates the legal construction of tiny homes within the state.

• L&I Washington

• Tiny House Communities: Legislation such as RCW 35.21.686 allows cities and towns to regulate the creation of tiny house communities. Landowners are required to provide necessary utility hookups and comply with relevant regulations, ensuring that tiny house communities are properly integrated into municipalities.

• Washington State Legislature

It's important to note that while these state-level regulations provide a framework for tiny home construction, local jurisdictions may have additional zoning laws and building codes that affect the placement and use of tiny homes. Therefore, it's advisable to consult local authorities to ensure compliance with all applicable regulations.

These legislative efforts in both California and Washington reflect a growing recognition of tiny homes as a practical solution to housing challenges, promoting increased housing diversity and affordability.
