Design & Planning Pomona, CA
Hello everyone,

I'm planning to build an ADU on my property in Pomona, California, and I'm hoping to get some clarity on the parking requirements. I've done quite a bit of research but still have some questions.

My property is a modest 6,500 square feet, and I'm trying to keep the overall project within a $150,000 budget. I've read that parking requirements can vary based on a few factors, such as proximity to public transit. My lot is about half a mile from the nearest bus stop, which I hope might impact the requirements favorably.

1. Given my situation, does the distance to public transit mean I can avoid adding extra parking spaces? I've seen some mention of exemptions but nothing very clear.

2. If I do need to provide additional parking, are there specific dimensions or design criteria I need to meet? My driveway isn't particularly large, and I'm wondering if I need to make adjustments.

3. Lastly, are there any other specific regulations related to ADU parking in Pomona that I should be aware of? I'm concerned about hitting unexpected costs or delays.

I appreciate any insights or advice you can offer. The last thing I want is to overlook something that could complicate the permitting process or blow my budget. Thanks in advance!

Hello,

It's great to hear that you're planning to build an ADU in Pomona. Navigating parking requirements can indeed be a bit tricky, so let's break down your questions one by one to help clarify what you need to know.

### 1. Proximity to Public Transit and Parking Exemptions

In California, state law has evolved significantly to encourage ADU development, and parking requirements are one area where you'll find some flexibility. According to state legislation such as AB-68, there are specific scenarios where parking requirements for ADUs can be waived. One of these scenarios includes properties located within half a mile of public transit.

Given your property is half a mile from the nearest bus stop, you may qualify for this exemption. This means you might not need to provide additional parking spaces for your ADU, which can be a significant cost and space saver. However, it is crucial to verify this with the Pomona Planning Department, as local interpretations or additional guidelines may apply.

### 2. Parking Design Criteria

If you do need to provide parking, there are standards you’ll need to meet. Typically, a parking space for an ADU must be at least 9 feet wide and 18 feet deep. If your driveway is limited in space, consider these alternatives:

- **Tandem Parking**: This is allowed in many jurisdictions for ADUs, and it might be a practical solution if your driveway is narrow.
- **On-Street Parking**: If allowed by Pomona ordinances and if street parking is available, this could count towards your parking requirement.

It's important to check whether these configurations are permissible by consulting the local building department. You may need to make driveway adjustments, which could involve additional costs and permits.

### 3. Local Regulations and Considerations

While state laws provide broad guidelines, local ordinances can specify additional requirements. In Pomona, ensure that:

- Your ADU complies with setback requirements, which might affect where parking spaces can be positioned.
- You are aware of any potential homeowner association (HOA) rules if applicable, which might impose further restrictions.

Pomona, like many cities, may have its own specific design guidelines or aesthetic considerations that could impact the exterior look of any added parking spaces.

### Cost and Timeline Considerations

For a budget of $150,000, managing costs effectively will be crucial. Here are some financial considerations:

- **Permitting Costs**: Expect to pay around $1,000 to $2,500 for permits. This can vary based on the complexity and scope of your project.
- **Construction Time**: The permitting process can take anywhere from 2 to 6 months, depending on the clarity of your plans and city workload. Construction itself could take an additional 6 to 12 months.

### Tips and Warnings

- **Start Early**: Engage with the Pomona Planning Department as early as possible to confirm requirements and gather necessary documents. This can help avoid delays.
- **Professional Assistance**: Consider hiring an ADU consultant or a local architect familiar with Pomona’s regulations. Their expertise can prevent costly mistakes and ensure compliance.
- **Budget Buffer**: Always maintain a contingency budget of at least 10-15% to account for any unexpected costs.

### Next Steps

1. **Contact Pomona Planning Department**: Confirm exemptions and specific requirements for your property.
2. **Consult a Professional**: Hire an ADU expert or architect to help design and plan the project.
3. **Prepare Your Application**: Ensure all application materials are complete and accurate to expedite the review process.
4. **Engage with Neighbors**: While not legally required, discussing your plans with neighbors can help prevent future disputes.

### Resources

- **Pomona Planning Department**: [Pomona’s official city website](https://www.pomonaca.gov) offers contact information and resources.
- **California Department of Housing and Community Development**: Provides comprehensive guides on ADU laws, including exemptions.

Building an ADU can be a rewarding endeavor that adds value to your property and provides additional income or living space. By understanding and navigating the parking requirements effectively, you can avoid hurdles and keep your project on track. Good luck with your ADU project in Pomona!
