Garage conversion vs new ADU construction in Fresno?

Hello,

As an experienced ADU consultant familiar with Fresno's regulations and building processes, I'd be happy to provide you with detailed insights to help guide your decision between converting your garage into an ADU and building a new standalone unit in your backyard. Let’s address your questions one by one:

### 1. Zoning Laws in Fresno

In Fresno, both garage conversions and new ADU constructions are generally permissible under local zoning laws, thanks to California's supportive ADU legislation, such as SB-9 and AB-68. These laws have significantly eased restrictions, allowing for greater flexibility in building ADUs. For instance, Fresno’s residential zones typically allow for ADU development without needing a variance. However, specific rules about setbacks, height restrictions, and lot coverage still apply.

For a garage conversion, you’ll likely benefit from relaxed setback requirements since the structure already exists. New constructions, on the other hand, must adhere to standard setbacks unless otherwise specified. Fresno typically requires a minimum of 4 feet from the rear and side property lines for new ADUs.

### 2. Permitting Processes

**Garage Conversion:** Generally, converting a garage is faster and less complex. The permitting process for a garage conversion can often be completed in 2-3 months, assuming no major structural changes. Since the existing structure is being repurposed, you'll primarily focus on meeting building codes for habitability, such as insulation, plumbing, and electrical systems.

**New Construction:** This process is typically more involved and could take 6-12 months from planning to completion, given the need for more comprehensive site plans, potential grading, and utility connections. It involves detailed architectural plans and potentially more scrutiny during inspections.

### 3. Common Unexpected Costs

**Garage Conversion:**
- **Structural Reinforcement:** Older garages may require foundation or structural upgrades, which can cost $5,000-$15,000.
- **Utilities:** Connecting or upgrading utilities can add $5,000-$10,000.
- **Insulation and Flooring:** Expect to spend $3,000-$6,000 for proper insulation and flooring.

**New Construction:**
- **Site Preparation:** Grading and site preparation can range from $5,000-$10,000.
- **Utility Hookups:** These can be quite expensive, ranging from $10,000-$20,000, depending on your current infrastructure.
- **Permitting Fees:** While Fresno has streamlined processes, these can still add up to $5,000-$8,000.

### 4. Impact on Property Taxes

Regardless of whether you convert a garage or build a new ADU, your property taxes will increase based only on the value added by the ADU, not the entire property reassessment. In Fresno, the added value is typically assessed based on the construction costs of the ADU. So, if your project costs $100,000, expect an assessment increase reflecting that amount, leading to a modest bump in property taxes.

### Additional Tips and Next Steps

- **Consult with Local Experts:** I recommend meeting with a local ADU specialist or architect who understands Fresno’s specific requirements. They can provide insights into any potential neighborhood-specific regulations.

- **Assess Your Needs:** Consider the long-term use of the ADU. If you foresee needing more space or have specific layout preferences, a new build might be more suitable despite the higher cost.

- **Visit Completed Projects:** If possible, visit other ADU projects in Fresno to get a tangible sense of space and layout.

- **Check Incentives:** Fresno may offer specific incentives or fee waivers for ADU construction, particularly if it aligns with affordable housing initiatives.

### Conclusion

Given your budget of $100,000, a garage conversion might be more feasible financially, offering a quicker turnaround and potentially fewer unexpected costs. However, if flexibility and space are priorities, and if you’re willing to slightly stretch your budget, exploring financing options for a new build might be worthwhile.

Your next steps should involve consulting with a local ADU consultant or architect to get a personalized assessment and cost estimate. This will ensure you have a clear understanding of both options in the context of your specific property and needs.
