1. Understanding the Basics of ADU Construction in San Mateo
In this article, we simplify the official document that is available on San Mateo city website.
Overview of ADUs: Accessory Dwelling Units (ADUs) are secondary housing units on the same lot as a main residence. They can help address housing shortages by providing more living spaces without the need to acquire new land.
Regulations in San Mateo: Local governments in San Mateo County, including Atherton, Hillsborough, Portola Valley, and Woodside, significantly rely on ADUs to meet affordable housing targets set by regional housing needs allocations (RHNA).
State Laws: Recent California laws mandate streamlined permitting for ADUs that meet specific criteria, removing the ability to condition these permits on affordability monitoring.
Affordability Monitoring: Although required to monitor ADU production and affordability biennially, the specific methods for verifying occupant income levels are not defined by the California Department of Housing and Community Development (HCD).
Community Efforts: San Mateo County jurisdictions have discussed strategies for monitoring ADU affordability and are considering regional efforts through collaborations like ABAG or 21 Elements.
Challenges and Strategies:
High land and construction costs in areas like Atherton make ADUs a more feasible option for adding affordable housing.
Strategies include zoning changes to allow more multi-family units, inclusionary housing ordinances, and educational programs to assist homeowners with ADU development.
Collaboration and Compliance: Towns are working together through initiatives like 21 Elements to develop housing policies and comply with state housing laws effectively.
2. The Role of ADUs in Meeting Housing Needs
Accessory Dwelling Units (ADUs) play a significant role in addressing housing needs in San Mateo County by providing affordable options. These units are small homes or apartments that share a lot with a larger primary residence. The state encourages the use of ADUs to help meet local housing demands, especially for low-income residents, by easing zoning restrictions and allowing them to count towards affordable housing quotas.
Key points about ADUs in San Mateo include:
Legislation Support: California laws support the development of ADUs by streamlining permitting processes and reducing construction restrictions.
Affordability Contribution: ADUs are considered a viable solution to increase affordable housing stock. They often serve low to moderate-income families, first responders, teachers, and other community workers who struggle with housing affordability in the area.
Local Efforts and Challenges: Local governments are working on methods to monitor and ensure ADUs are used for affordable housing. However, there's a challenge in verifying the income levels of occupants to ensure the units remain affordable.
Community Impact: ADUs help diversify housing options and can integrate affordable units seamlessly into existing neighborhoods without altering their character.
Monitoring and Verification: Efforts are being made to establish regional programs for monitoring the affordability and proper use of ADUs, which will help in aligning with state housing requirements and ensuring that the intended benefits of ADUs are realized.
By integrating ADUs into their housing strategies, San Mateo County aims to address its acute housing shortage effectively while supporting community members in need of affordable housing options.
