Introduction to SB-9: Explaining the Purpose and Significance

The California Housing Crisis has driven legislative action aimed at increasing housing availability and affordability. Senate Bill 9 (SB-9), also known as the California Housing Opportunity and More Efficiency (HOME) Act, is a pivotal piece of legislation designed to address these challenges. SB-9 enables homeowners to subdivide their lots and build additional residential units, including Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs).

In this comprehensive guide, we'll demystify SB-9 by exploring its key provisions, benefits, challenges, and practical steps for compliance. We’ll also showcase real-life success stories to highlight the transformative potential of SB-9.

Understanding the Key Provisions of SB-9 for Small Business Owners and Homeowners

The core aim of SB-9 is to streamline the process for creating additional housing units on single-family zoned properties. Here are the critical aspects:

1. Lot Split Provisions:

  • Homeowners can split their existing lots into two, allowing for the construction of additional housing units.
  • Each new lot must be at least 40% of the original lot size and have frontage on a public street.

2. New Construction and Conversions:

  • Homeowners can convert existing structures into new SB-9 units or build new ones.
  • The maximum height for new construction is one story, up to 18 feet.
  • Setbacks must be at least 20 feet in the front and 4 feet on the sides and rear.

3. Units and Size:

  • You can build up to two primary units per lot, with a combined maximum gross floor area of 1,800 square feet per lot.
  • Additional units, such as ADUs and JADUs, are permitted, but must comply with specific size and design standards.

4. Parking Requirements:

  • A minimum of one enclosed garage space per SB-9 unit is required.

5. Design Requirements:

  • Detached units cannot be side-by-side; rear units must be positioned directly behind front units.
  • Attached units should not be symmetrical and must appear as a single building if they have zero setbacks at the front.

The Benefits of SB-9 for Property Owners and Local Communities

Benefits of SB-9

SB-9 offers numerous advantages for property owners and the broader community:

1. Increased Property Value:

  • By adding new units, homeowners can significantly increase the value of their properties.

2. Rental Income:

  • Additional units provide opportunities for rental income, helping offset mortgage costs or boosting overall financial stability.

3. Affordable Housing:

  • SB-9 aims to increase the housing supply, making homes more accessible and affordable for families and individuals.

4. Community Growth:

  • The law encourages sustainable growth by promoting more housing within existing urban areas, reducing the need for sprawl.

5. Environmental Benefits:

  • By utilizing existing residential spaces more efficiently, SB-9 can reduce the environmental impact associated with new housing developments.

Challenges and Concerns: Addressing Common Misconceptions

While SB-9 has many benefits, it also faces opposition and misconceptions:

1. Overdevelopment Concerns:

  • Some fear that SB-9 will lead to overdevelopment and alter neighborhood character.
  • However, the law includes provisions to maintain aesthetic harmony and prevent misuse, such as prohibiting short-term rentals and requiring owner occupancy.

2. Infrastructure Strain:

  • Critics argue that increased density could strain existing infrastructure.
  • SB-9 addresses this by mandating that new units cannot interfere with flood control or storm drain easements and must comply with local development standards.

3. Legal and Administrative Hurdles:

  • Navigating the legal requirements and obtaining the necessary permits can be daunting.
  • Engaging with experts and leveraging resources like legal counsel and planning consultants can ease this process.

How to Comply with SB-9: Practical Steps and Advice

SB-9 Implementation

Implementing SB-9 in your property involves several steps:

1. Verify Eligibility:

  • Ensure your property meets the eligibility criteria specified in Government Code Section 65852.21(a).

2. Planning and Design:

  • Work with architects and planners to design units that comply with SB-9’s requirements, including size, setbacks, and parking.

3. Obtain Permits:

  • Submit your plans to the local planning department and secure the necessary permits.
  • Comply with all objective development standards of the underlying zone, except those superseded by SB-9.

4. Construction and Compliance:

  • Engage reputable contractors to carry out the construction work.
  • Ensure all units adhere to the stipulated height, design, and parking requirement. Consult Our Experts

5. Legal Documentation:

  • If you’re splitting your lot, sign an affidavit stating your intent to occupy one unit as your primary residence for at least three years.
  • Submit a restrictive covenant prohibiting the use of units as short-term rentals.
