Can I build an ADU myself in Irvine?

Hello and welcome to the exciting journey of building an ADU in Irvine! You're on the right track by getting informed about the regulations and requirements. Let's tackle your questions one by one to ensure your project goes smoothly.

### Can You Build the ADU Yourself?

Yes, as a homeowner, you can technically build the ADU yourself, but there are a few caveats. According to California law, you do not need to be a licensed contractor to perform construction work on your own property. However, you must act as the "owner-builder," which means you assume all liability and responsibility for the project, including adherence to building codes and safety standards.

While this can save costs, it's crucial to evaluate your skills realistically. ADU construction involves various trades like plumbing, electrical, and structural work, which must pass city inspections. Hiring licensed subcontractors for specialized tasks could help you avoid common pitfalls and ensure compliance with local codes.

### Setback and Parking Requirements

In Irvine, the setback requirements for ADUs typically include:

- **Rear Setback**: Often 4 feet, but verify with the latest local codes.
- **Side Setback**: Generally 4 feet as well.

As for parking, recent California laws like SB-13 and AB-68 have relaxed these requirements for ADUs. If your property is within half a mile of public transit or if the ADU is part of the existing primary structure, additional parking is typically not required. Since you mentioned having a long driveway, this might suffice if additional parking is needed, but verify with the city’s planning department.

### Permitting Process

The permitting process in Irvine can indeed be complex, but here's a step-by-step guide to make it more manageable:

1. **Pre-Design Meeting**: Before you begin, it's wise to schedule a pre-design consultation with the city’s planning department. They can provide you with specific feedback on your lot and proposed ADU plans.

2. **Design and Drafting**: Create detailed architectural plans. You might consider hiring a designer or architect familiar with Irvine’s ADU regulations to ensure your plans meet all requirements.

3. **Submit Plans for Review**: Submit your plans to the Irvine Building and Safety Division for review. This process usually takes around 6-8 weeks, depending on the workload of the department.

4. **Plan Check and Revisions**: Expect some back-and-forth during the plan check phase. Be prepared to make revisions as requested by city reviewers.

5. **Obtain Permits**: Once your plans are approved, you'll be issued the necessary building permits. Permit fees in Irvine can range from $5,000 to $10,000, depending on the complexity and size of your ADU.

6. **Construction**: With permits in hand, you can begin construction. Regular inspections will be required at various stages, such as foundation, framing, plumbing, and electrical work.

### Budget Considerations

With a budget of $100,000, you'll need to plan carefully. Here are some general cost estimates for Irvine:

- **Design and Permitting**: $10,000 - $15,000
- **Construction Costs**: $150 - $300 per square foot, depending on the materials and complexity.
- **Utilities and Landscaping**: $5,000 - $10,000

Given these estimates, you might consider building a smaller ADU or simplifying the design to stay within budget.

### Helpful Tips and Warnings

- **Research Local Regulations**: Stay updated on Irvine’s specific ADU regulations by visiting the city's planning department website or contacting them directly.
- **Quality Over Cost**: Cutting corners can lead to costly repairs or non-compliance issues later. Focus on quality construction.
- **Project Management**: Consider hiring a project manager if the scope feels overwhelming. They can coordinate the different trades and ensure the project stays on track.

### Next Steps

1. **Contact Irvine’s Planning Department**: Set up a meeting to discuss your project specifics.
2. **Consult Professionals**: Even if you’re doing most of the work yourself, consulting with an architect or contractor for initial guidance can be invaluable.
3. **Gather Resources**: Check out resources like the California ADU Handbook for additional guidance.

Building an ADU can be a rewarding project, adding value to your property and providing additional living space. With careful planning and execution, you'll not only meet Irvine's regulations but also create a beautiful and functional addition to your home.
