Can I convert my garage to an ADU in Long Beach?

Garage Conversion Long Beach, CA
Hi everyone,

I'm considering converting my garage into an ADU in Long Beach, CA, and I could use some advice. My property is about 6,500 square feet, and the garage is detached, roughly 400 square feet. We have a growing family, and I'm hoping this conversion can provide some extra living space or potential rental income. I've done some research, and I know ADUs have become popular due to recent California laws making it easier to build them, but I'm still unclear about a few specifics.

First, are there specific zoning laws or restrictions in Long Beach that I should be aware of, especially concerning garage conversions? I've heard something about setbacks and height restrictions, but I’m not sure how they might apply to my situation.

Also, I’m working with a budget of around $75,000. Is this a realistic figure for a garage conversion, considering permits, construction, and any unforeseen expenses? I want to ensure I plan financially before diving in.

Lastly, does anyone know about the parking requirements? I've read that converting a garage might require replacing parking spots somewhere on the property, but I'd love to hear from those who've navigated this process already.

Any guidance or experiences would be greatly appreciated. I'm eager to get this project underway, but I want to make sure I'm not missing anything crucial. Thanks in advance!

Hello,

Converting your garage into an Accessory Dwelling Unit (ADU) in Long Beach is a fantastic way to add living space or generate rental income, and it's great that you're considering this. With the recent changes in California laws, the process has indeed become more streamlined, but there are still several important details to consider. Let’s address your questions step-by-step.

### Zoning Laws and Restrictions

**Zoning and Setbacks:** In Long Beach, as in many California cities, ADUs are encouraged under state laws like SB 9 and AB 68, which have reduced many zoning barriers. However, local municipalities can still impose specific requirements. Generally, detached ADUs must adhere to certain setbacks – typically 4 feet from the side and rear property lines. Since your garage is detached, these setbacks will likely apply. Check with the Long Beach Development Services to see if your existing garage location complies, as sometimes existing structures like garages can be grandfathered in, avoiding some setback requirements.

**Height Restrictions:** Detached ADUs in Long Beach generally have a height limit of 16 feet. If you're considering adding a loft or a second story, you may need additional approvals or variances.

### Budget Considerations

**Cost Estimate:** With a budget of $75,000, you are within a reasonable range for a garage conversion in Long Beach. Typical garage conversion costs can range from $50,000 to $100,000, depending on the complexity and the finishes you choose. Here’s a rough breakdown:
- **Design and Permits:** $5,000 - $10,000
- **Construction (including utilities):** $40,000 - $60,000
- **Finishes and Appliances:** $10,000 - $20,000

Keep in mind that unforeseen expenses can arise, especially if there are issues with the foundation or if significant electrical or plumbing upgrades are needed.

### Parking Requirements

Under California state law (SB 1069 and AB 68), converting a garage into an ADU no longer mandates replacement parking if your property is within half a mile of public transit, which is often the case in Long Beach. However, it’s important to confirm this with the city to ensure compliance, as local ordinances can sometimes have specific nuances.

### Steps to Get Started

1. **Consult with Long Beach Development Services:** Before breaking ground, visit or contact the Long Beach Development Services for a pre-application meeting. They can provide detailed information on specific zoning laws and requirements.

2. **Hire a Professional:** Engage with an architect or a design-build firm experienced in ADUs. They can help with design plans and navigating the permit process. Local firms familiar with Long Beach codes can streamline the process significantly.

3. **Obtain Permits:** Prepare to submit detailed design plans for approval. The permit process can take anywhere from a few weeks to a couple of months, depending on workload and complexity.

4. **Construction Timeline:** Once permits are approved, a typical garage conversion might take 3 to 6 months. This includes time for inspections at various stages of construction.

5. **Utilities and Upgrades:** Plan for potential upgrades to utilities like plumbing, electrical, and sewer lines. These are critical and can sometimes be a significant part of your budget.

### Helpful Tips

- **Energy Efficiency:** Consider incorporating energy-efficient features such as LED lighting, energy-efficient windows, and insulation. This not only complies with California’s Title 24 energy efficiency standards but also reduces long-term costs.

- **Design Considerations:** Think about the layout carefully to maximize space. Features like open floor plans, loft beds, or built-in storage can make a smaller space more livable.

- **Tax Implications:** Be aware that adding an ADU can affect your property taxes. Consulting with a tax professional can help you understand potential implications.

### Resources

- **Long Beach Development Services Website:** This is an invaluable resource for local zoning laws and permit information.
- **California Department of Housing and Community Development (HCD):** Offers resources and guidance on statewide ADU standards and laws.
- **Local ADU Workshops:** These can provide hands-on guidance and allow you to connect with other homeowners who have undertaken similar projects.

By taking these steps and conducting thorough research, you’ll be well-equipped to successfully convert your garage into a functional and compliant ADU. Good luck with your project, and feel free to ask more questions as you proceed!
