What are the parking requirements for ADUs in Los Angeles?

Permits & Regulations Los Angeles, CA

Hi everyone,

I’m planning to build an ADU on my property in Los Angeles, and I'm trying to wrap my head around the parking requirements. I've read that if you're within ½ mile of public transit, you don't need to provide additional parking for the ADU. My lot is about 7,500 sq ft, and I'm located around 0.4 miles from a major bus stop, so I think this might apply to me. However, I'm also considering converting my existing two-car garage into the ADU, which complicates things.

From what I've gathered, converting the garage means I might need to find space for two uncovered parking spots for my main residence. My budget is fairly tight, so I want to avoid any unforeseen costs that could come with adding these spaces.

Here are my questions:

1. Does my proximity to the bus stop mean I definitely don’t need to provide any parking for the ADU?
2. If I convert my garage into the ADU, is it mandatory to provide those two uncovered spaces, or are there any exceptions?
3. Are there any creative solutions that others have used to meet these parking requirements without major expenses?

I’d really appreciate any insights or experiences from those who have navigated this process in LA. Thanks in advance!

Certainly! As you're planning to develop an Accessory Dwelling Unit (ADU) on your property in Los Angeles, it's crucial to understand the parking requirements and how they may impact your project. Let's address your questions based on the current regulations and provide guidance for your specific situation.

### Understanding Parking Requirements for ADUs in Los Angeles

1. **Proximity to Public Transit**:
According to Los Angeles Municipal Code (LAMC) Section 12.22.A.33, one of the major benefits for ADU developers is the relaxation of parking requirements if the property is located within ½ mile of public transit. Since your property is approximately 0.4 miles from a major bus stop, you do not need to provide additional parking for the ADU itself. This regulation supports the City's broader efforts to encourage the use of public transit and reduce vehicle dependency.

2. **Garage Conversion Considerations**:
When converting an existing garage into an ADU, the situation becomes a bit more complex. The same ordinance stipulates that while no additional parking is needed for the ADU, the parking originally provided by the garage must be replaced. This means that if you convert a two-car garage, you will need to provide two uncovered parking spaces for your main residence elsewhere on your property.

### Solutions and Strategies

- **Explore Your Property Layout**: Review your property layout to identify potential areas where you could accommodate two uncovered parking spaces. Depending on the size and layout of your yard, you might be able to use existing driveways or paved areas, which can minimize additional costs.

- **Consider Tandem Parking**: If space is limited, tandem parking can be a viable option. This involves parking one car directly behind the other, which can be a practical solution if your driveway is long enough to accommodate both vehicles.

- **Landscaping Adjustments**: In some cases, you might need to make minor landscaping adjustments to create parking space. This could involve removing non-essential structures or modifying existing landscaping features.

### Financial Considerations

- **Budgeting for Parking Adjustments**: While the primary focus is on reducing costs, remember to budget for any necessary changes to your property, such as driveway expansions or landscaping modifications. These costs can vary based on the extent of the work required.

### Navigating the ADU Process

- **Ministerial Approval**: In Los Angeles, ADU projects benefit from a streamlined approval process, typically taking 4-6 months. This ministerial approval means that as long as your plans comply with zoning and building codes, they should be approved without discretionary review.

- **Consult Professionals**: It may be beneficial to consult with an architect or an ADU specialist who can provide personalized advice and help you navigate the permitting process efficiently. They can also help ensure your plans comply with all relevant codes and ordinances.

### Helpful Tips for ADU Development in Los Angeles

- **Keep Up with Regulations**: ADU regulations can change, so it's important to stay informed about any updates. For instance, starting January 1, 2024, owner-occupancy requirements will be eliminated per AB 976, which may impact your decisions if you're considering renting the ADU.

- **Plan for Utilities**: Ensure that your plans include provisions for connecting the ADU to utilities like water, electricity, and sewer. These connections can sometimes present unanticipated costs.

- **Impact Fees**: Be aware that while ADUs under 750 square feet are exempt from impact fees, ADUs 750 square feet and larger will incur proportional fees. This could influence the size and scope of your project.

### Next Steps

1. **Site Analysis**: Conduct a thorough analysis of your property to determine the best location for the required uncovered parking spaces.

2. **Consult with Experts**: Engage with a local architect or ADU consultant to review your plans and provide tailored advice. Their expertise can be invaluable in navigating the permitting process and ensuring compliance.

3. **Submit Permits**: Prepare and submit your building permit application, ensuring all aspects of your ADU project, including parking, meet the requirements set by LAMC 12.22.A.33.

4. **Monitor the Process**: Keep track of your permit application status and be proactive in addressing any feedback or required changes from city officials.

By understanding and applying these regulations effectively, you can move forward with your ADU project with confidence. I wish you the best of luck and success with your new development in Los Angeles! If you have any further questions, feel free to reach out.
