Everything New with ADUs: 2025 ADU Rules and Regulations Now in Effect

  • 07 Jan, 2025

  • ADU

A new year for you, and a new day for ADUs. Several laws went into effect on January 1, 2025 regarding ADUs. Here are some highlights that you should know about if you’re looking to build an ADU or have an existing ADU. 

Unpermitted ADUs and JADUs 

Previously, unpermitted ADU and JADUs that were constructed prior to January 1st, 2020 were deemed ineligible to be permitted. However, AB 2533 stipulates that those structures can receive permits, provided that they adhere to health and safety codes. If they currently fail to comply, homeowners are to be given a checklist of issues to fix before permits can be issued. Furthermore, AD 2533 prohibits local agencies from charging penalties or fees in connection to an ADU or JADU’s unpermitted status. 

Multifamily Unit ADUs

Prior to SB 1211, multifamily lots were only allowed to have a maximum of 2 ADUs. However, as of today, multifamily lots can have a maximum of 8 ADUs, as long as the number of ADUs does not exceed the number of units contained in the multifamily primary dwelling. Additionally, these ADUs do not require off-street parking. 

ADUs in Coastal Zones

Historically, it’s been harder for homeowners in designated coastal zones – like Los Angeles –  to build ADUs. Now, SB 1077 requires that local governments receive guidance on how to amend the coastal zone regulations to streamline and simplify the process of getting approval for their ADUs. Furthermore, interested members of the public will be able to comment on local guidance proposals related to ADUs in their communities. 

ADUs and the Law

Recent rules and regulations around ADUs haven’t loosened restrictions. In 2025, homeowners may have an easier time with both approving, permitting, and building their ADUs. Nagar Builders is proud to always stay abreast of the latest legal changes in the ADU landscape. Work with us on your ADU today!

Client Testimonials

Thank you Nagar! The entire process was smooth and easy. I called them and they were quick to provide an estimate. Once they explained pricing to me and I agreed, they were ready to work ASAP! I hired them to add an office space to my home. My office went fully remote due to COVID so I wanted to have a full office space where I could concentrate. It was amazing to see the entire construction process, from building the walls, to adding a half bathroom. The finished product is truly impeccable.

Avi and his team from Nagar builders remodeled our bathroom and kitchen and they did a phenomenal job!!! His team is very skilled, knowledgeable, and clean. Avi was also very professional and he made so many suggestions to us as we weren’t even sure what style and colors we wanted, he pretty much helped us design everything. I wouldn’t hire anyone other than Avi to do any work at my house, I’m very satisfied with his work and professionalism and I highly recommend this company!! Thank you again Avi!

I hired Nagar Builders to remodel my kitchen. The house I currently live in (in West Hollywood) was passed down to me from my mother. … We added a waterfall counter, tile backsplash, new appliances, and cabinets in a nice warm and inviting blue color. It also felt like they worked fast than estimated so I was able to use my new kitchen earlier than expected! If it weren’t for the pandemic, I would be hosting all the time!

Vanessa R.

We hired Avi from Nagar Builders to help us solve a multitude of issues with our backyard including landscaping with artificial turf, replace our old rotting deck and install vinyl gates, remediate failing stucco wall and foundation, and more. … we are very happy with the look of our backyard now – definitely will bring back Avi for future work!
