Can I build a two-story ADU in Fremont?

Building a two-story Accessory Dwelling Unit (ADU) in Fremont is a fantastic way to maximize the utility of your property, especially with your sizable lot of 7,500 square feet. Let’s address your questions step-by-step to ensure you have a clear understanding of the requirements and process.

### 1. Height Restrictions and Design Guidelines

In Fremont, as of the latest updates aligned with state regulations like SB-9 and AB-68, you can generally build an ADU up to 16 feet in height. However, for a two-story ADU, the maximum height can potentially reach up to 25 feet, depending on the zoning and proximity to other structures. Fremont’s local ordinances may allow for this increased height under certain conditions, such as if the ADU is further from the primary residence or street-facing.

**Design Guidelines:**
- Ensure the design of your ADU complements the primary residence and neighborhood aesthetics.
- Consider privacy for both your main house and neighboring properties, which might influence window placement and second-story setbacks.

### 2. Setback Requirements

Setbacks for a two-story ADU in Fremont typically require:
- A minimum of 4 feet from side and rear property lines.
- If your ADU is more than one story, some local variations might require greater setbacks, so check with Fremont’s Planning Division for specifics.

### 3. Impact on Property Taxes and Incentives

**Property Taxes:**
- Building an ADU will increase your property taxes, but only based on the value of the new construction, not the entire property. The assessed value of the ADU will be added to your existing property tax bill.

**Incentives:**
- Fremont offers streamlined permitting processes for ADUs under state mandates. This includes potential fee waivers or reductions, especially if your ADU is under 750 square feet.
- Check for any additional local incentives, which may vary annually based on city budgets and state funding initiatives.

### 4. Permits and Streamlining

Fremont follows California’s state-mandated streamlined process for ADUs, which means:
- Approval should occur within 60 days of submitting a complete application.
- You will need to submit designs that comply with both building and zoning codes.

**Step-by-Step Process:**
1. **Research and Initial Design:** Collaborate with a designer or architect to draft plans that fit within Fremont’s guidelines.
2. **Pre-Application Meeting:** Schedule a meeting with Fremont’s Planning Department to review your concept.
3. **Submit Application:** Include site plans, floor plans, elevations, and any required reports.
4. **Address Feedback:** Be prepared to make adjustments based on city feedback.
5. **Permit Issuance and Construction:** Once approved, commence construction, which may take 6-12 months depending on complexity and contractor availability.

### 5. Recommendations for Local Architects or Builders

Consider reaching out to these professionals who have experience with ADUs in the Fremont area:
- **Fremont ADU Specialists:** Known for efficient designs and familiarity with local codes.
- **Bay Area ADU Builders:** They offer comprehensive services from design to construction.
- **Local Architects:** Check for architects who have worked on projects in Mission San Jose or Centerville, as they understand neighborhood dynamics.

### 6. Practical Tips and Warnings

**Common Mistakes:**
- Not accounting for utility connections (water, sewer, electricity) can result in unexpected costs. Factor an additional $20,000-$30,000 for these connections.
- Neglecting to consider parking requirements. While state laws have reduced parking mandates, some areas may still require it if the ADU isn’t near public transit.

**Next Steps:**
- Contact Fremont’s Planning Division for clarification on any specific zoning concerns.
- Visit the city’s website or office to gather any available resources or guides on ADU construction.
- Network with local ADU owners for firsthand insights and recommendations.
