The demand for constructing Accessory Dwelling Units in California is increasing as they offer passive income to homeowners and affordable housing options to those on a tight budget. According to statistics, there was a significant increase in the number of ADU rentals leased in 2019, with 8,000 rentals compared to less than 1,000 rentals in 2000. 

This number continues to grow rapidly due to the population increase in the Bay Area, as well as the multiple benefits of ADU remodeling. However, building ADUs in Cupertino can be stressful, and it is crucial to find a contractor familiar with zoning laws and regulations.

What is ADU and What does it mean in Housing?

ADU housing refers to the construction of independent dwelling units on the same property as a primary home. Commonly known as accessory apartments, granny flats, or backyard cottages, ADUs are secondary units that have their own bathroom, kitchen, and entrance but are connected to the main property’s water, power, and gas hookups. It is essential to note that ADUs cannot be sold separately as they are legally attached to the primary lot.

Benefits of ADU Remodeling in 2023:

Generate Passive Income by Renting Out Your ADU

If you have an ADU, renting it out can be a great way to earn extra income. However, it is important to check with your city beforehand as regulations can vary. 

Increase Your Property Value

Building an ADU not only increases your property value but is also cost-effective since it does not require the purchase of additional land or infrastructure. If you want to add more living space to your property and increase its value, building an ADU may be the best option.

Use Your ADU as a Guest Space

Having an extra living space is practical for both lifestyle and financial reasons. As people’s needs change over time, an accessory dwelling unit can be used to house in-laws, kids, extended family, or friends, providing the perfect amount of privacy for both guests and hosts.

Low-Cost Housing for Seniors and Caretakers

California Health and Safety Code requires counties and cities to develop plans to incentivize ADUs to offer affordable rent for low to moderate-income families. If you are interested in renting out your ADU for this purpose, Julz Corp builders can help you with the process.

Space  for Young Adults and College Graduates

An ADU can provide young adults or college graduates with personal space while remaining close to home. Whether you have teens who want their own space or young graduates who are not yet ready to move away, an ADU can be an ideal solution.

Your New Home Office or Workout Space

An ADU can also be used as a home gym or office, providing space and privacy for all family members. It is perfect for those who want to work out or work from home without disturbing others in the house.
