What Are ADUs?

In the ever-changing world of California real estate laws and regulations, Accessory Dwelling Units (ADUs) are hot topics. These smaller living spaces, often called granny flats or in-law units, or tiny houses…You get the idea.  

ADUs are at the heart of California’s strategy to make housing more affordable and available while also being in line with the state’s real estate laws and regulations. This is good news for everyone, no matter the size of your wallet – a happy California is a good place to live. 

ADUs come in many shapes and sizes, and might be converted garages, or separate outbuildings on the property of a main house. ADUs are versatile, supporting everything from intergenerational living to providing predictable rental income and a flexible use space in your backyard. Recognizing the value of ADUs to supplement a dire housing crisis, the State of California has updated its real estate laws and regulations to make them easier to build. ADUs have so many uses:

Home Offices: With the rise of remote work, ADUs provide the perfect secluded space for a home office, allowing for a clear separation between work and home life.

Creative Studios: Artists, musicians, and writers can use ADUs as creative studios, providing a dedicated space for inspiration and work without the distractions of the main house.

Wellness and Fitness Spaces: An ADU can be transformed into a personal gym, yoga studio, or meditation space, offering privacy and convenience for health and wellness activities.

Rental Income: Beyond long-term leasing, which is great for predictable income, ADUs can be listed on short-term rental platforms like Airbnb for additional income, catering to tourists, visitors in the area, or traveling healthcare workers.

Guest Houses: For people who frequently host guests, an ADU can serve as a comfortable and private guest house, which makes a better visit for everyone.

Educational Spaces: ADUs can be personal libraries, study rooms, or  even neighborhood tutoring centers, providing a quiet and dedicated space for learning and education.

Workshops and Crafting Areas: For those with hobbies that require space, like woodworking, pottery, or large-scale art projects, ADUs offer the room and separation needed for such activities.

Entertainment Rooms: ADUs can be set up as entertainment or game rooms, housing collections of movies, video games, or tabletop games for hosting game nights or movie screenings.

Home Bars or Mini-Cafes: For enthusiasts of coffee culture or home bartending, ADUs can be transformed into personal cafes or bars, offering a unique space for entertaining and experimenting with drinks.

Multigenerational Living Spaces: While not entirely unconventional, using ADUs for multigenerational living allows families to stay close while maintaining independence and privacy.

California Loves ADUs

California experienced a significant increase in ADU construction following  several legislative changes in the past decade which were directly aimed at easing restrictions and encouraging their development. Between 2018 and 2019, the number of ADU permits increased dramatically from 5,911 to 15,571.This surge was most evident in California’s major cities –  Los Angeles, San Diego, and the San Francisco Bay Area, but other areas of the state also saw meaningful increases.

The state’s efforts to promote ADU construction as a solution to the housing shortage have led to regulatory changes that have significantly raised the amount of ADU permits filed and approved annually. And the growth trajectory of ADUs in California has been impressive over a longer period as well, with ADU permit numbers showing an 11x increase from 2016 to 2019 – From 1,269 ADU permits in 2016 to 14,702 in 2019.

The Legislative and regulatory efforts to simplify and encourage the development of ADUs in California have obviously paid off, and it’s reflective of a significant shift towards more flexible and diverse housing options for a flexible and diverse population. 

Recent Changes Since 2020 to Real Estate Laws and Regulations

Under the evolving real estate laws and regulations, California has been busy updating laws to encourage the development of more ADUs. For example, in 2020, laws made it simpler for homeowners to add ADUs by getting rid of some older rules, like needing a big lot or extra parking. 

Then, in 2022, new rules made it even easier to get ADUs approved and let properties have up to two ADUs, boosting the number of homes in a neighborhood. These steps show California’s commitment to using ADUs to help solve the housing crisis. 

2024 Updates to ADU Laws in California

Continuing its proactive approach, California introduced new legislation in 2024 aimed at further simplifying the ADU development process. These updates streamline permitting processes and introduce financial incentives for low and middle-income property owners, reducing the cost and complexity of construction. The expansion of eligibility to multifamily buildings opens up even more opportunities for creating new housing units. Additionally, the state is mindful of community harmony, implementing guidelines to ensure ADUs integrate well into neighborhoods without straining local infrastructure or parking, all within the framework of updated real estate laws and regulations.

The Bigger Picture

These changes are reshaping the real estate world, affecting how properties are developed and valued. Easier ADU rules mean homeowners can make the most of their property, whether that’s through extra rental income or increased property value. For renters and buyers, it means more options! 

California’s push to make ADUs easier to build, especially with the 2024 updates, is a big step towards tackling the state’s housing issues. These changes encourage property owners to explore new opportunities and help create a more varied and welcoming housing market.
