Do I need to replace parking if I convert my garage in Torrance?

Garage Conversion Torrance, CA

Hi everyone,

I'm considering converting my detached two-car garage into an ADU on my property in Torrance, California. My lot is about 6,000 square feet, and I'm trying to be smart about the budget given that construction costs add up quickly. From what I've read, garage conversions are a great way to add living space and potentially some rental income, but I'm a bit stuck on the parking regulations.

I understand that some cities in California might have rules about replacing parking if you convert a garage. I've seen mixed information on whether Torrance requires this or not. Does anyone have experience with this specific issue in Torrance? I'm trying to figure out if I need to allocate part of my budget to create additional parking spots, or if I can avoid that cost.

Also, since my property is on a slightly sloped street, would that impact my options for replacing parking, if required? And, are there any specific permits or additional fees I should be aware of if I do need to replace parking?

I've reached out to the city planning department, but I'd love to hear from anyone who has gone through this process. Your insights would be really helpful in planning and budgeting for this project. Thanks in advance!

Hello there,

Thank you for reaching out with your questions about converting your garage into an Accessory Dwelling Unit (ADU) in Torrance! You're on the right track by seeking clarity on parking requirements, as this is a common area of concern for many homeowners embarking on ADU projects in California. Let's break down your questions and provide you with a comprehensive guide.

### 1. **Parking Replacement Requirements**

In California, state laws such as AB-68 and SB-9 have significantly relaxed ADU development regulations, including parking requirements. Specifically for garage conversions, you are not required to replace parking spaces that are lost due to the conversion of a garage into an ADU. This is a statewide rule aimed at encouraging more ADUs to alleviate housing shortages. Therefore, in Torrance, you are generally not required to provide replacement parking if you convert your garage into an ADU.

### 2. **Impact of Street Slope**

A sloped street can influence your project's design and construction approach, particularly if you were considering alternative parking solutions like a driveway extension or carport. However, since you aren't required to replace parking, the slope should not directly impact the need for additional parking. If you do decide to accommodate parking elsewhere on your lot, consider consulting with a civil engineer to evaluate grading and drainage, ensuring compliance with local building standards.

### 3. **Permits and Fees**

For the garage conversion, you'll need to secure several permits from the City of Torrance, including:

- **Building Permit**: Essential for structural modifications.
- **Electrical, Plumbing, and Mechanical Permits**: If your ADU will include utilities.
- **Zoning Approval**: To ensure compliance with local land-use regulations.

The cost for these permits can range from $2,000 to $5,000, depending on the scope of work and specific requirements. Be sure to budget for these as part of your project costs.

### 4. **Timelines**

The timeline for converting a garage into an ADU in Torrance can vary. Here’s a general breakdown:

- **Design and Planning**: 1-3 months. Work with an architect or designer familiar with local codes to create plans.
- **Permitting Phase**: 2-4 months. Torrance is generally efficient, but review times can vary based on workload and project complexity.
- **Construction**: 3-6 months. This depends on the contractor's schedule and the complexity of the conversion.

### 5. **Local Considerations in Torrance**

Torrance has specific zoning ordinances you need to comply with, such as setbacks, height limits, and maximum ADU size. The maximum size for a detached ADU in Torrance is typically 1,200 square feet, but since you're converting a garage, the existing footprint will guide your size constraints.

### 6. **Common Mistakes to Avoid**

- **Ignoring Local Design Standards**: Ensure your ADU design complements the neighborhood aesthetics, as some communities have design guidelines.
- **Underestimating Utility Upgrades**: Many garage conversions require substantial upgrades to utilities. Get a detailed assessment early on.
- **Skipping Over Professional Help**: Engage professionals familiar with Torrance’s specific requirements, especially for structural and utility work.

### 7. **Next Steps and Resources**

- **Contact a Local ADU Specialist**: They can provide insights into recent projects and trends in Torrance.
- **Visit the City of Torrance's Planning Department**: Their staff can provide specific insights and answer any lingering questions about your project.
- **Consult Torrance's ADU Ordinance**: Available on the city’s website for detailed regulations.

### 8. **Helpful Tips**

- **Explore Financing Options**: Consider state and local programs offering low-interest loans or subsidies for ADU construction.
- **Join Local Forums or Groups**: Connect with other homeowners who’ve completed ADU projects in Torrance for shared experiences and advice.

By taking these steps, you can ensure a smooth process for your ADU conversion. Good luck with your project, and don't hesitate to reach out if you have more questions as you move forward!
