What are Santa Rosa's specific SB-9 regulations?
I'm a homeowner in Santa Rosa trying to navigate the complexities of SB-9, specifically regarding lot splits. My property is just under 10,000 square feet, and I'm considering splitting the lot to potentially build an additional unit. I've done some preliminary research and understand that SB-9 allows for lot splits, but I'm unsure about the specific regulations Santa Rosa has implemented around this.
First, does anyone know if there are particular zoning restrictions or additional criteria Santa Rosa enforces beyond state requirements? I've read conflicting information and want to ensure I'm compliant from the get-go.
Second, my budget for this project is rather tight, so I'm concerned about any hidden costs, such as utility hookups or required infrastructure improvements. Does anyone have experience with these potential expenses in Santa Rosa?
Third, I live in a neighborhood that has a mix of single-family homes and some multi-unit buildings. How does this diversity in housing types impact the approval process or neighborhood feedback on such projects?
Lastly, if anyone has gone through the application process here, how was your experience with the city's planning department? Any tips or things you wish you'd known beforehand would be incredibly helpful.
I appreciate any guidance or experiences you can share. Thanks in advance!

Navigating the complexities of SB-9 and local regulations can be daunting, but I'm here to help break it down for you. Let's tackle your questions systematically.
### Understanding Santa Rosa's SB-9 Regulations
#### 1. Zoning and Additional Criteria
SB-9, enacted in 2021, allows for the splitting of lots in single-family residential zones and the construction of up to two units on each resulting parcel. However, each city, including Santa Rosa, can impose its own set of additional requirements.
In Santa Rosa, specific zoning ordinances might affect your project. Here are key points to consider:
- **Minimum Lot Size and Split Requirements:** While SB-9 sets a minimum lot size of 2,400 square feet for each subdivided parcel, Santa Rosa may have additional criteria based on your zoning district. It’s crucial to consult the City's Planning and Economic Development Department to confirm these specifics.
- **Setbacks and Design Standards:** Santa Rosa may impose additional setback requirements beyond the state minimums. Typically, SB-9 requires a minimum 4-foot side and rear yard setback, but local variances might apply.
- **Owner-Occupation Requirements:** SB-9 mandates that one of the units on the split lot must be owner-occupied for a minimum of three years post-split. This could impact your plans if renting both units is part of your strategy.
#### 2. Potential Costs and Hidden Expenses
Budgeting for an ADU or lot split can be challenging. Here are some potential costs specific to Santa Rosa:
- **Utility Hookups:** Expect to pay between $5,000 and $10,000 per unit for utility connections (water, sewer, electricity). The exact cost depends on proximity to existing infrastructure and local utility fees.
- **Infrastructure Improvements:** If your project requires road widening, sidewalk installation, or other infrastructure improvements, these can add $10,000 to $50,000 to your budget.
- **Permit Fees:** Permit fees in Santa Rosa can range from $5,000 to $15,000, depending on the complexity of your project and the need for variances or additional reviews.
#### 3. Impact of Housing Diversity on Approval
In Santa Rosa’s diverse neighborhoods, the presence of multi-unit buildings can sometimes ease the approval process, as the area may already be zoned or accustomed to higher density. However, community feedback can be mixed. It's wise to engage with your neighbors early in the process to gauge and address their concerns.
#### 4. Santa Rosa Planning Department Experience
The City of Santa Rosa is generally supportive of SB-9 projects, but the process can be complex. Here's a brief rundown of what to expect:
- **Initial Consultation:** Schedule a pre-application meeting with the Planning Department. They can provide invaluable insights specific to your property and project.
- **Application Submission:** The application process typically takes 60-90 days, assuming no major setbacks or community objections.
- **Approval and Construction:** Once approved, construction timelines vary. Expect 6-12 months from breaking ground to completion, factoring in potential delays due to weather or supply chain issues.
### Tips and Warnings
- **Thorough Research:** Before committing to a lot split, ensure detailed research on zoning, neighborhood plans, and any potential CEQA (California Environmental Quality Act) implications.
- **Professional Guidance:** Consider hiring a local architect or project manager experienced with Santa Rosa’s regulations. Their expertise can streamline the process and potentially save costs.
- **Community Engagement:** Proactively engage with your neighborhood association or community groups. Transparency and responsiveness to feedback can facilitate smoother approvals.
### Next Steps and Resources
1. **Contact Santa Rosa’s Planning and Economic Development Department:** They can provide the most accurate and up-to-date information on local ordinances and the application process.
2. **Consult a Land Use Attorney or Experienced ADU Consultant:** Especially if your property has unique challenges or if you anticipate opposition.
3. **Explore Financing Options:** Investigate local programs that may offer financial assistance or incentives for developing ADUs or utilizing SB-9.
4. **Review SB-9 and AB-68 Texts:** Familiarize yourself with the full texts of these laws to ensure compliance and leverage their provisions effectively.
5. **Join Local Forums or Attend City Meetings:** Engaging with local real estate forums or attending city council meetings can provide additional insights and networking opportunities.
By following these steps and leveraging available resources, you can navigate the complexities of SB-9 in Santa Rosa with greater confidence. Best of luck with your project—it's an exciting opportunity to make a positive impact on housing availability!
