How long does ADU construction take in Pomona?

Hello,

Building an Accessory Dwelling Unit (ADU) in Pomona, CA, is a fantastic way to add value to your property and provide additional living space. While the process can be complex, understanding timelines, costs, and potential pitfalls can help you navigate it more smoothly. Let's dive into your questions with some specific insights relevant to Pomona.

### Timeline for Permitting and Construction

**Permitting Process:**

1. **Pre-Application Phase (1-2 months):** Before you submit your plans, it's wise to consult with a designer or architect familiar with Pomona's building codes. This can help streamline the process and avoid costly redesigns down the line.

2. **Plan Submission and Review (2-4 months):** Once your plans are ready, submit them to the Pomona Building and Safety Division. The City of Pomona, like many in California, has been working to streamline ADU approvals due to state mandates (AB-68, SB-9) designed to promote housing. However, plan reviews typically take 6 to 8 weeks initially, with additional time needed for any required revisions.

3. **Permit Approval:** With everything in order, you can expect permit issuance within 2-4 months from your initial submission. Factors such as workload at the city office, completeness of your application, and responsiveness to requested changes can affect this timeline.

**Construction Phase:**

1. **Site Preparation and Foundation (1 month):** This includes clearing land, excavation, and pouring the foundation. Given your lot size, ensure your plans comply with setback requirements and any local zoning laws.

2. **Building the Shell (2-3 months):** Framing, roofing, and siding generally take a few months. Weather conditions and contractor availability can impact this phase.

3. **Interior Work (2-3 months):** Plumbing, electrical, insulation, drywall, and flooring follow. Utility hookups can sometimes present delays if there are unforeseen issues with existing infrastructure.

4. **Final Inspections and Finishing Touches (1 month):** Schedule inspections as soon as key phases are complete to avoid bottlenecks. Final touches, such as painting and landscaping, are completed after passing inspections.

**Total Construction Time:** Expect about 6 to 9 months for construction once permits are in hand, assuming no major delays.

### Costs and Budget Considerations

For a budget of around $150,000, you're looking at a standard-sized ADU (approximately 400-600 square feet). Here are some cost breakdowns:

- **Design and Permits:** $10,000 - $15,000
- **Site Work and Foundation:** $20,000 - $30,000
- **Construction:** $80,000 - $100,000
- **Utilities and Hookups:** $10,000 - $20,000
- **Finishing and Landscaping:** $10,000 - $15,000

### Potential Delays and How to Avoid Them

1. **Utility Hookups:** Coordinate early with utility companies. Check if any upgrades to the existing systems are required and factor in time for these adjustments.

2. **Inspections:** Schedule inspections ahead of time and ensure that all work complies with local codes to avoid re-inspections.

3. **Contractor Reliability:** Vet contractors thoroughly. Ask for references, check past work, and ensure they have experience with ADUs in Pomona.

### Tips for Staying on Track

- **Pre-Plan Thoroughly:** Invest time in the design and planning phase. A well-thought-out plan will save time and money in the long run.

- **Maintain a Contingency Fund:** Set aside about 10-15% of your budget for unexpected expenses. Construction often reveals unforeseen issues, especially in older properties.

- **Stay Informed on Regulations:** Keep up with state and local regulations (e.g., SB-9) that may impact your project. Pomona has specific guidelines on parking, height restrictions, and setbacks that must be adhered to.

### Next Steps and Resources

1. **Consult with ADU Specialists:** Consider hiring a consultant or a contractor who specializes in ADUs and has a track record in Pomona. They can offer invaluable insights and project management skills.

2. **Visit the City of Pomona’s Planning Division:** They can provide guidance on local zoning laws and answer specific questions about your property.

3. **Join Local ADU Forums or Groups:** Engaging with others who have gone through the process can provide practical advice and support.

Building an ADU is a significant investment, but with careful planning and a clear understanding of the process, you can achieve a successful outcome. Good luck with your project in Pomona!
