Can I do a lot split under SB-9 in Sunnyvale?

Hello there!

It's great to hear that you’re considering taking advantage of California’s SB-9 regulations to split your lot in Sunnyvale and potentially increase your property value with an ADU. Let's break down your questions to give you a clearer picture of your next steps.

### Understanding SB-9 and Local Ordinances

**SB-9 Overview:** SB-9, effective from January 1, 2022, allows homeowners in single-family residential zones to split their lots and build additional units. Under state law, each resulting lot must be at least 1,200 square feet, and SB-9 allows for the addition of up to two residential units on each lot, potentially a main house and an ADU.

**Local Ordinances:** Sunnyvale, like many cities, may have additional ordinances that impact your project. Sunnyvale requires compliance with objective zoning standards, subdivision standards, and design standards when applying for a lot split under SB-9. Check for any local amendments or specific conditions that Sunnyvale might have implemented. It's advisable to contact the City of Sunnyvale Planning Division directly or review their website for any specific local ordinances that might affect your application.

### Zoning and Neighborhood Covenants

Sunnyvale's residential zones typically support single-family dwellings, but given your interest in utilizing SB-9, ensure your property is not subject to any historic preservation rules or specific neighborhood covenants that could hinder a lot split or ADU construction. It’s crucial to review the title report for your property which might reveal such covenants. Consulting with a local real estate attorney or a planning consultant could provide clarity and save you from future legal headaches.

### Budget Considerations

**Lot Split Costs:** The cost of a lot split in Sunnyvale can vary but plan for application fees, survey costs, and potential legal fees, totaling between $10,000 to $20,000. This can vary based on specific surveyor fees and any complexities encountered during the process.

**ADU Construction Costs:** Building a modest ADU in Sunnyvale typically ranges from $150,000 to $250,000, depending on size, design, and finish quality. Your budget of $150,000 might be tight, but it's feasible if you opt for a smaller, more basic design.

**Additional Costs:** Be prepared for additional costs such as utility hookup fees, which can range from $5,000 to $15,000, depending on the current infrastructure and the specifics of your site. Additionally, plan for permit fees, which can range from $3,000 to $8,000.

### Timeline

**Lot Split Timeline:** Completing a lot split, from application to approval, can take 6 to 12 months. This includes time for surveys, city review, and addressing any conditions set by the city.

**ADU Construction Timeline:** Once your lot is split, expect 6 to 10 months for the design, permitting, and construction of your ADU.

### Steps to Move Forward

1. **Research and Consultation:** Begin by consulting with a local architect or planning consultant familiar with Sunnyvale’s regulations. They can provide insights into feasibility and potential design solutions within your budget.

2. **Engage a Surveyor:** Hire a licensed land surveyor to assess your property and prepare the necessary documentation for the lot split.

3. **City Consultation:** Meet with Sunnyvale’s Planning Division to discuss your plans and gather detailed information on any local requirements or restrictions.

4. **Prepare Financially:** Secure financing that accounts for both the known costs and unforeseen expenses. A contingency of 10-20% beyond your budget is prudent.

5. **Utility Assessment:** Contact local utility providers to evaluate the cost and feasibility of additional hookups or modifications needed for the new lot and ADU.
