What is AB 434?

AB 434 is a new law in California. It’s all about ADUs. But what exactly is it? Let’s break it down:

  • AB stands for “Assembly Bill.” It’s a type of law.
  • 434 is just its number. It helps people find the right law.
  • This law was made to make building ADUs easier.
  • It changed some old rules about ADUs.
  • The law started working on January 1, 2022.

AB 434 is a big deal for anyone interested in ADUs. It makes the whole process simpler. Now, let’s look at why this law is so important.

Why Was AB 434 Created?

California needed more homes. That’s where AB 434 came in. Here’s why it was made:

  • Many people couldn’t find affordable homes.
  • Cities were running out of space to build.
  • ADUs could help, but they were hard to build.
  • Old rules made ADUs expensive and slow to make.
  • People wanted an easier way to build ADUs.

AB 434 was created to solve these problems. It aimed to make ADUs a real option for more people. The law wanted to cut down on red tape. It also wanted to speed up the building process.

Key Changes Brought by AB 434

AB 434 made big changes to ADU rules. Here are the main ones:

Faster Approvals:

  • Cities now have to approve ADU plans faster.
  • They only get 60 days to say yes or no.
  • If they don’t decide in time, the ADU is automatically approved.

Easier Parking Rules:

  • You don’t need to add a parking space for your ADU.
  • This makes it easier to build ADUs in tight spaces.

Size Matters:

  • ADUs can now be bigger than before.
  • You can build up to 1,200 square feet in most cases.
  • That’s about the size of a small house.

Fewer Fees:

  • Cities can’t charge as many fees for ADUs now.
  • This makes building an ADU cheaper.

More Options:

  • You can now build an ADU and a small “junior ADU” on the same property.
  • This gives homeowners more choices.

These changes make a big difference. They open up new possibilities for homeowners. Let’s look at each change in more detail.

Faster Approvals: The 60-Day Rule

One of the biggest changes in AB 434 is the 60-day rule. Here’s how it works:

  • Cities used to take a long time to approve ADU plans.
  • Now, they only have 60 days to decide.
  • This is called “ministerial approval.”
  • It means cities can’t take forever to make up their minds.
  • If they don’t decide in 60 days, your ADU is automatically approved.

This rule is a game-changer. It stops cities from dragging their feet. It also gives homeowners more certainty. You know you’ll get an answer quickly. This makes planning much easier.

Easier Parking Rules

Parking used to be a big headache for ADU builders. AB 434 changed that:

  • Before, you often had to add a parking space for your ADU.
  • This was hard in cities where space is tight.
  • Now, you don’t need to add parking for most ADUs.
  • This is true even if you’re close to public transit.
  • It’s also true if you’re in a historic district.

These new rules make it much easier to build ADUs. You don’t need a big driveway or extra land. This opens up ADU options for more homeowners.

Size Matters: Bigger ADUs Allowed

AB 434 lets you build bigger ADUs. Here’s what changed:

  • Old rules often limited ADUs to 800 square feet.
  • Now, you can build up to 1,200 square feet in most cases.
  • That’s enough space for a small family.
  • You can have multiple bedrooms and a full kitchen.
  • The size can vary based on your main house’s size.

These new size rules give you more options. You can build an ADU that really fits your needs. It could be a home for grandparents or adult children. Or it could be a rental unit to earn extra income.

Fewer Fees: Making ADUs More Affordable

Building anything costs money. But AB 434 tries to keep ADU costs down:

  • Cities used to charge lots of fees for ADUs.
  • These fees could add thousands of dollars to the cost.
  • Now, many of these fees are not allowed.
  • Cities can’t charge impact fees for ADUs under 750 square feet.
  • For bigger ADUs, fees must be proportional to the main house.

This change makes ADUs more affordable. It removes a big barrier for many homeowners. Now, more people can consider building an ADU.

More Options: Junior ADUs

AB 434 introduces a new concept: Junior ADUs. Here’s what you need to know:

  • A Junior ADU is a very small living space.
  • It’s usually created within an existing house.
  • It can be up to 500 square feet.
  • It might share a bathroom with the main house.
  • You can now build both an ADU and a Junior ADU on one property.

This gives homeowners even more flexibility. You could have a bigger ADU in the backyard. And you could also convert part of your house into a Junior ADU. This creates lots of options for multi-generational living or rental income.

How AB 434 Affects Different Cities

AB 434 is a state law. But it affects different cities in different ways:

  • All cities in California must follow the basic rules of AB 434.
  • But cities can add their own rules too.
  • Some cities might have stricter design standards.
  • Others might offer extra help for ADU builders.
  • You should always check your local city rules.

This means your experience might vary depending on where you live. But overall, AB 434 makes things easier everywhere in California.
