SB9 Lot Split : Detail Guide

In recent years, California has been grappling with a pressing need for affordable housing solutions and increased housing density. In response to this growing concern, the state has implemented several housing regulations, including Senate Bill 9 (SB 9) which introduces the concept of (SB9) lot splitting

Shortage of affordable homes in California

Why does this happen?

It is mainly because of the state’s housing crisis. In his article “The California Housing Crisis: Where We Started and Where We’re Going” Sydney Schoeller explains, “Access to affordable housing, however, is becoming increasingly unattainable for many Americans. Last year, rates of chronic homelessness increased by 20%, nearly a million people were evicted, homeless camps continued to expand across the country

To address the issue of affordable housing, the government has introduced bills such as SB9, SB886, and AB2097. These bills aim to implement measures that ensure accessible housing options for everyone.

What is The SB9 Rule in California?

The SB9 rule in California refers to Senate Bill 9, a piece of legislation that was passed to address the housing shortage and promote infill development in the state. 

SB9 allows property owners to split their single-family residential lots into two separate lots, each of which can be developed with a residential unit. This means that a single lot can potentially accommodate two homes. The legislation also includes provisions for building accessory dwelling units (ADUs) on the newly split lots.

Importance and Relevance Of SB9 Lot Split in Real Estate

By allowing property owners to split their lots, it creates opportunities for the construction of additional housing units, potentially doubling the number of homes on a single lot. This can help alleviate the housing affordability crisis and provide more options for prospective homebuyers.

Importance and Relevance Of SB9 Lot Split

According to data from the California Department of Housing and Community Development, as of 2021, the state needs to build an estimated 1.8 million new housing units by 2025 to keep up with demand. 

Secondly, the legislation promotes infill development, which encourages the efficient use of existing infrastructure and resources. Instead of expanding into undeveloped areas, SB9 Lot Split enables the development of new housing within already established neighborhoods. This can help reduce urban sprawl and preserve open spaces.

A report by the Terner Center for Housing Innovation at UC Berkeley found that “allowing for lot splits and increased density in single-family zones can lead to a substantial increase in affordable housing production. The report estimates that “implementing policies similar to SB9 could result in the creation of approximately 700,000 additional housing units statewide.

Furthermore, SB9 Lot Split can have positive economic impacts. Increased housing supply can stimulate the construction industry and generate employment opportunities.

Environmental Considerations:

Environmental regulations and considerations, such as wetlands, endangered species habitats, or other ecological factors, can restrict lot splitting. “The state government code goes on to say that exemptions can be made for sites that have adopted sufficient fire hazard mitigation measures. So if your proposed development meets specific fire safety requirements, your property may be eligible for SB 9.” According to the article, SB 9 in Very High Fire Severity Zones

Infrastructure Limitations:

The availability and capacity of infrastructure such as roads, utilities, and services may impact the feasibility of lot splitting. In his article, “California’s Crumbling Infrastructure: An Urgent Priority”,José Cisneros wrote that , “Approximately 83% of Californians live, work and play in cities. As the state has struggled to balance its budget, it has cut infrastructure funding programs and taken local revenues. “
