Historical context of California's ADU regulations

It is no secret that California’s real estate market is among the most expensive and competitive in the nation. The state’s population is projected to grow from 39 million in 2020 to 50 million by 2030, and the demand for housing is only expected to increase. In order to meet this demand, California must build more housing – and fast.

One way to increase the state’s housing supply is by legalizing and encouraging the development of accessory dwelling units (ADUs), also known as granny flats or in-law units. ADUs are small, self-contained housing units that are typically attached to or located on the same property as a single-family home.

While ADUs have been around for centuries, they have only recently gained popularity in California. This is due in part to the state’s high housing costs and the need for more housing, but also because of changes in state law that have made it easier to build ADUs.

In 2016, California enacted a law ( Assembly Bill 2299) that streamlined the ADU approval process and reduced many of the fees associated with building them. The law also lifted many of the local restrictions that had previously prevented homeowners from building ADUs on their property.

As a result of these changes, the number of ADUs built in California has increased dramatically. From 2016 to 2017, the number of ADUs permitted in the state increased by more than 250%. And as of 2019, there were an estimated 10,000 ADUs in California – a number that is expected to grow in the years to come.

There are many benefits to building ADUs, both for homeowners and for the state as a whole. For homeowners, ADUs can provide additional income, as they can be rented out to tenants. They can also be used as a place for aging parents or adult children to live, which can help to keep families together. And for the state, ADUs can help to address the housing crisis by increasing the housing supply.

If you’re considering building an ADU on your property, it’s important to be aware of the historical context of California’s ADU regulations. This will

The current state of California's ADU regulations

As of early 2020, the California Legislature is considering a bill that would repeal the Costa-Hawkins Rental Housing Act. This bill, if passed, would allow cities and counties to enact rent control ordinances on all residential units, including single-family homes, condominiums, and units built after 1995. This would have a profound impact on the rental housing market in California, as well as the development of accessory dwelling units (ADUs).

In recent years, the development of ADUs has exploded in popularity, as they provide a way to add additional rental units to the housing stock while circumventing many of the restrictions placed on new construction. However, under Costa-Hawkins, rent control ordinances cannot apply to units built after 1995, meaning that many ADUs are not subject to rent control.

If the bill to repeal Costa-Hawkins is passed, it would open up the possibility for cities and counties to enact rent control ordinances that would apply to all residential units, including ADUs. This could have a significant impact on the development of ADUs, as developers would need to factor in the possibility of future rent control when deciding whether or not to build them.

Of course, the bill to repeal Costa-Hawkins is far from guaranteed to pass, and it remains to be seen what effect it would have on the development of ADUs if it did. However, it is clear that the current state of California's ADU regulations is in flux, and that the future of the ADU market in the state is far from certain.

The future of California's ADU regulations

As we all know, the housing crisis in California is only getting worse. The number of people living in poverty is on the rise, and the number of homeless people is increasing at an alarming rate. The state of California is in desperate need of more affordable housing, and one way to address this issue is to loosen up the regulations surrounding accessory dwelling units (ADUs).

ADUs are small, secondary units that are attached or detached from a primary residence. They can be used for a variety of purposes, such as providing extra income through rental income, or providing housing for elderly family members or young adults who are just starting out.

There are a number of benefits to allowing more ADUs in California. For one, it would increase the amount of affordable housing in the state. ADUs are typically much cheaper to build than traditional single-family homes, so they can be a more affordable option for low- and middle-income families.

Additionally, ADUs can help to alleviate the housing crisis in California by providing more housing units overall. Even if some of these units are rented out at market rate, this still increases the number of units available for people who need them.

Finally, ADUs can help to reduce traffic and congestion in California. This is because they provide an alternative to traditional single-family homes, which often require people to commute longer distances to work or school. By providing more housing units closer to where people work and play, ADUs can help to reduce traffic and improve the quality of life for Californians.

There are a few cities in California that have already started to loosen up their regulations surrounding ADUs. For example, the city of San Francisco recently passed a law that makes it easier to build ADUs. And, the city of Los Angeles is currently considering a similar measure.

As more and more cities begin to recognize the benefits of ADUs, it's likely that the state of California will eventually follow suit. This would be a huge victory for affordable housing in California, and it would go a long way towards alleviating the state's housing crisis.
