Design & Planning Torrance, CA

Hi everyone,

I'm in the early stages of planning an ADU addition to my property in Torrance, CA, and I'm a bit stumped on the parking requirements. My lot is about 8,500 square feet, and I have a tight budget, so I want to make sure I get everything right from the start without unnecessary expenses or surprises.

From what I've gathered, there seems to be some flexibility in parking regulations for ADUs, especially if they're within a certain distance from public transit. My house is about a mile from the nearest bus stop. Does that mean I might be exempt from additional parking requirements?

Also, I'm curious about how these regulations might differ if my ADU ends up being detached versus attached to the main house. I read somewhere that the rules could vary, but I'm not entirely sure how.

Another thing I'm puzzled about is the impact of converting my existing garage into an ADU. Would I need to compensate for the lost parking spots by adding more spaces elsewhere on my property?

Lastly, are there any exceptions or recent changes in local ordinances that I should be aware of? I've seen some discussions online mentioning new state laws that might override local rules, but I can't seem to pin down the details for Torrance.

I'd really appreciate any insights or experiences you all could share! Thanks in advance for your help.

Hello!

I'm glad to hear you're considering adding an ADU to your property in Torrance. Navigating the parking requirements and other regulations can be complex, but I’m here to help clarify things for you. Let's break down your questions step by step.

### Parking Requirements for ADUs in Torrance

#### 1. Proximity to Public Transit

California state law, specifically under SB-1069 and AB-68, has relaxed parking requirements for ADUs significantly, especially if your property is located within half a mile of public transit. However, since your property is about a mile from the nearest bus stop, this particular exemption wouldn’t automatically apply. Yet, if there are other transit routes or stops closer than the one you mentioned, it’s worth verifying their distances as they might qualify you for an exemption.

#### 2. Attached vs. Detached ADU

In Torrance, the parking requirements generally do not differ between attached and detached ADUs. As per state law, if your property qualifies for an exemption (e.g., within a half-mile of public transit, in a historic district, or in a designated parking impact zone), neither form would require additional parking. However, if none of these exemptions apply, you would typically be required to provide one parking space for the ADU.

#### 3. Garage Conversion

Converting an existing garage into an ADU is a popular option, and there are a few considerations here. Under California law, when a garage is converted into an ADU, you are not required to replace the parking spaces lost from the conversion. This can be a big benefit if your lot has limited space.

#### 4. Local Ordinance Considerations

Torrance, like many cities in California, must comply with state regulations regarding ADUs, which have preempted more restrictive local ordinances. However, always check with the local planning department for any specific local amendments or updates that might affect your project. Torrance might have additional guidelines, such as design requirements, that you need to follow.

### Costs and Timelines

- **Design and Planning**: Budget around $5,000 to $10,000 for architectural plans and permits. Check with local architects familiar with Torrance’s planning department for accurate quotes.
- **Construction Costs**: In Torrance, building an ADU can range from $150,000 to $300,000 depending on size, materials, and finishes.
- **Timeline**: From design to completion, expect a realistic timeline of 12 to 18 months. This includes planning, permitting, and construction phases.

### Steps to Get Started

1. **Research and Planning**: Review the California ADU Handbook and Torrance's local guidelines. Consider consulting with a local ADU specialist or architect who can provide tailored advice.

2. **Site Evaluation**: Determine the best location on your property for the ADU. Consider factors like sunlight, existing landscaping, and how it impacts your main house.

3. **Design and Permitting**: Engage with an architect or designer early. They’ll help with your design and ensure compliance with all relevant codes. Submit these plans to the Torrance Planning Department for approval.

4. **Budget Planning**: Secure financing if necessary. Look into local incentives or state funding programs that might offset some costs.

5. **Builder Selection**: Once permits are approved, select a reputable contractor with experience in ADU projects within Torrance.

### Helpful Tips

- **Utility Connections**: Be aware that utility connections can be a significant cost. Discuss with your contractor about the most efficient way to connect the ADU to existing utilities.
- **Avoiding Common Mistakes**: Ensure all permits are in place before construction begins to avoid fines.
- **Community Input**: Although not always required, consider informing neighbors about your plans to maintain good community relations.

### Resources and Next Steps

- **Contact Torrance Planning Department**: They can provide specific guidance and confirm any recent changes in local ordinances.
- **California Department of Housing and Community Development (HCD)**: Their website has comprehensive resources and updates on state laws impacting ADUs.
- **Local ADU Workshops**: Attend workshops or seminars in your area; they often provide valuable insights and networking opportunities with professionals.

Adding an ADU is a fantastic way to increase your property value and create additional living space. With careful planning and adherence to regulations, your project can be a smooth and successful endeavor. Good luck, and feel free to reach out if you have more questions!
