Design & Planning Pomona, CA

Hi everyone,

I'm in the early stages of planning an ADU on my property in Pomona, California, and I'm trying to wrap my head around the parking requirements. My lot is about 8,000 square feet, and while I've done some research, the specifics are a bit confusing.

From what I've gathered, some parking requirements might be waived if I'm near public transit, but I'm not sure what qualifies as "close" in this context. My place is about a mile from the nearest bus stop—does that count?

Another concern is the existing layout of my property. I have a single-car garage and a narrow driveway. Would I need to make changes to accommodate additional parking, or can the current setup be considered adequate?

Also, I've read that certain types of ADUs might have different requirements. I'm considering a detached unit in the backyard, but I'm unsure if that affects the parking rules.

Lastly, are there any exceptions or creative solutions other homeowners have found to meet these requirements? My budget is tight, so I'm trying to avoid any major changes that could drive up costs.

Any insights or experiences with Pomona's regulations would be greatly appreciated. Thanks in advance!

Hello and welcome to the exciting journey of planning your ADU in Pomona! Navigating the parking requirements can indeed be complex, but I’m here to help break it down for you.

### Understanding Pomona's Parking Requirements

1. **Proximity to Public Transit:**
Based on California state laws, specifically SB-1069 and AB-68, parking requirements for ADUs can be waived if your property is within half a mile of public transit. Unfortunately, since your property is about a mile from the nearest bus stop, this doesn't automatically qualify for a waiver. However, it might still be worth contacting the Pomona Planning Division to discuss any local nuances or additional criteria that might influence this rule.

2. **Existing Layout Considerations:**
Given that you have a single-car garage and a narrow driveway, it’s crucial to assess how these can accommodate the parking needs. Generally, Pomona may require one additional parking space for a newly constructed detached ADU, unless exceptions apply. However, if your existing garage or driveway can accommodate this without impeding access, you might not need to make significant changes. Many homeowners have successfully used tandem parking in driveways to meet requirements, provided there's enough space for vehicles to maneuver safely.

3. **ADU Type and Its Impact:**
Since you’re considering a detached ADU, the parking requirements typically remain consistent unless your property is part of a historic district or has other specific zoning overlays, which might have additional stipulations. Detached units generally require careful planning to ensure compliance with setback and lot coverage rules, but these don’t usually affect parking unless specified by local ordinances.

### Exceptions and Creative Solutions

In Pomona, as in many parts of California, there are several exceptions and creative solutions to explore:

- **Convert Existing Structures:** If you convert an existing garage into an ADU, you might be exempt from replacing the lost parking space, thanks to state legislation. This can be a cost-effective way to add an ADU without needing additional parking.

- **Shared Driveways and Carports:** Consider the possibility of installing a carport or utilizing shared driveway arrangements if your property layout allows. These often require less investment than constructing new garage spaces.

- **On-Street Parking:** If your neighborhood permits, utilizing available on-street parking can also be a practical solution, though it’s essential to verify with local regulations.

### Costs and Timelines

- **Parking Adjustments:** Depending on the complexity, creating additional parking spaces could range from $5,000 to $15,000, considering paving, permits, and any necessary landscaping.

- **Timeline:** The permitting process in Pomona for ADUs can take anywhere from 3 to 6 months, factoring in design review and any necessary appeals. Starting with a pre-application consultation with the city can expedite this.

### Practical Steps Forward

1. **Consult with Pomona Planning Division:** Schedule a meeting with the local planning department to discuss your specific situation. They can provide detailed information on current ordinances and any potential for variances.

2. **Hire a Professional:** Consider engaging an architect or ADU consultant familiar with Pomona. Their expertise can help in designing an efficient layout and navigating through the permitting process.

3. **Budget Planning:** Clearly outline your budget, considering both construction and any potential modifications to your property. This will help in making informed decisions as you proceed.

4. **Stay Updated on Regulations:** Laws can change, and staying informed can help you take advantage of any new exemptions or reduced requirements.

### Conclusion

Planning an ADU is a rewarding venture that can add significant value to your property. With the right approach, understanding local regulations, and perhaps a bit of creative thinking, you can navigate the parking requirements effectively without breaking the bank. Don’t hesitate to reach out to local forums or homeowner groups in Pomona for shared experiences and tips.

Good luck, and feel free to ask more questions as you move forward with your project!
