Do HOA rules override ADU laws in Pomona?

Zoning & Legal Pomona, CA
Hi everyone,

I'm hoping to get some clarity on a situation I'm navigating here in Pomona, CA. I'm considering adding an ADU (Accessory Dwelling Unit) to my property to accommodate my aging parents, but I'm a bit confused about the interaction between state ADU laws and my HOA's rules.

I live on a lot that's about 6,500 square feet, and I've set aside roughly $150,000 for this project. I've done some homework and understand that California has supportive laws for ADU construction to help alleviate housing shortages, but my HOA has some pretty strict regulations. I'm worried these might throw a wrench in my plans.

Here are my specific questions:

1. If there's a conflict between state ADU laws and my HOA's restrictions, which takes precedence?

2. Are there any particular aspects of HOA rules that tend to get challenged or overridden by state laws, especially here in Pomona?

3. Has anyone else in Pomona dealt with a similar situation, and how did you navigate the process?

4. Lastly, are there any tips or resources you could recommend to ensure I'm fully compliant with both the city's and my HOA's regulations before I proceed?

I want to make sure that I'm following all the right steps and not running into any unexpected legal hurdles. Any insights would be greatly appreciated!

Thanks in advance for your help!

Hello there,

Your question about navigating the complexities of building an ADU in Pomona while dealing with HOA regulations is a common concern among homeowners in California. Let’s address your specific queries and provide you with a clear pathway forward.

### 1. Precedence of State ADU Laws over HOA Rules

California state laws regarding ADUs are designed to streamline the construction process and reduce barriers, including those potentially posed by HOAs. Under **California Government Code Section 65852.2**, state law generally supersedes any local ordinances or HOA rules that would effectively prohibit the construction of an ADU. This means that if your HOA’s regulations conflict with state law, the state law will typically take precedence.

In particular, **Senate Bill 13 (SB-13)** and **Assembly Bill 68 (AB-68)**, among others, emphasize the state's commitment to easing restrictions on ADU construction to address housing shortages. They mandate that local governments, including HOAs, cannot impose overly restrictive requirements that would hinder the development of ADUs.

### 2. Common HOA Challenges and State Law Overrides

HOAs often impose restrictions related to aesthetic uniformity, parking, or setbacks. However, state law restricts HOAs from enforcing regulations that would unreasonably prevent the development of an ADU. For instance, **AB-670** invalidates HOA covenants that effectively bar the construction of ADUs.

That said, HOAs can still impose reasonable standards as long as they do not impede ADU creation. These include aesthetic guidelines that complement the existing community's appearance without prohibiting construction.

### 3. Navigating the Process in Pomona

Drawing from experiences in Pomona, a strategic approach involves proactive communication with your HOA. Here’s a step-by-step guide:

1. **Review HOA Documents:** Carefully examine your HOA’s CC&Rs (Covenants, Conditions, and Restrictions) to identify any clauses regarding ADUs.

2. **Consult with the HOA:** Engage with your HOA early in the planning process to discuss your intentions. Transparency can often lead to a smoother process.

3. **Obtain City Permits First:** Before confronting potential HOA issues, secure necessary permits from the City of Pomona. The city’s Planning Division is a valuable resource and can guide you through compliance with local zoning laws.

4. **Professional Consultation:** Consider hiring an ADU specialist or an attorney familiar with local regulations to navigate both city and HOA requirements effectively.

### 4. Ensuring Compliance with City and HOA Regulations

Here are some tips and resources to ensure compliance:

- **City of Pomona’s Planning Division:** Visit their website or office to get the latest ADU application forms, zoning information, and permit requirements. They can also inform you about any recent amendments specific to Pomona.

- **Budgeting:** With a budget of $150,000, you are in a reasonable range. Construction costs for ADUs in Pomona typically range from $150 to $300 per square foot, depending on the complexity and finishes.

- **Timeline:** Expect a timeline of 12 to 18 months from planning to completion, factoring in design, permitting, construction, and final inspections.

- **Local Workshops or Seminars:** These can provide insights into the latest regulations and offer networking opportunities with professionals who have experience with ADUs in Pomona.

### Additional Tips and Warnings

- **Document Everything:** Keep detailed records of all communications with your HOA and the city. This can be invaluable if disputes arise.

- **Parking Requirements:** Ensure you comply with state parking requirements for ADUs, although state laws have relaxed these significantly.

- **Avoid Common Mistakes:** Misunderstanding setback requirements or ignoring fire safety regulations are typical pitfalls. Always cross-check these details with Pomona’s zoning requirements.

### Next Steps

1. **Engage with a Local Architect or ADU Consultant:** They can help design an ADU that meets both your needs and community standards.

2. **Schedule a Meeting with the Pomona Planning Division:** This will help clarify any outstanding questions about local building codes or permit processes.

3. **Join Local Forums or Groups:** Online forums or community groups can be valuable for sharing experiences and advice about ADU projects in Pomona.

By following these steps and leveraging available resources, you should be well-prepared to navigate the intersection of state ADU laws and HOA rules in Pomona. Best of luck with your project!
