1. Initial Consultation & Needs Assessment
- Free Project Review: When you first reach out to a local ADU contractor like Fabrick Construction, you’ll typically start with a free or low-cost consultation. This is your chance to talk through your goals — whether you're aiming for rental income, a guest suite, or a multigenerational unit.
- Feasibility Check: The contractor will evaluate your lot, existing home, and local zoning to assess whether an ADU is viable. Because San Diego has very specific ADU regulations, a local expert is invaluable here.
2. Design & Planning
- Architectural Design or Pre-Approved Plans: You can work with an architect or use county-approved ADU plans. San Diego County even offers pre-approved plans for detached ADUs, which can speed up permitting.
- Site Survey & Utility Review: The contractor and/or architect will study your site’s topography, setbacks, and how utilities (water, sewer, electricity) connect.
- Cost Estimation & Budgeting: Based on the design, the contractor will share an estimate that accounts for construction, permits, and material costs.
- Financing Options: Fabrick can help you explore funding options — whether it's a home equity loan, construction loan, or even local incentive programs (e.g., the San Diego Housing Commission’s ADU Finance Program).
3. Permitting Process
- Permit Application Submission: A building permit is always required for ADUs in San Diego.
- Regulatory Approvals: Depending on your property, you may need additional approvals — for example, a Coastal Development Permit if you're in the coastal overlay zone.
- Plan Review & Revisions: After submitting your plans, the city or county reviews them and may request revisions. This can take several cycles.
- Permit Issuance: Once approved, your permit is issued, and you pay the necessary fees.
- Regulatory Compliance: Your ADU must meet all zoning, building, and safety codes, including septic requirements if you’re not connected to the sewer.
4. Pre-Construction
- Site Preparation: The site is cleared, graded, and prepared for foundation work.
- Utility Coordination: Your contractor will coordinate with utility providers and ensure proper connections.
- Subcontractor & Material Planning: Local contractors like Fabrick have trusted subcontractors in San Diego, which helps streamline scheduling and reduce surprises.
5. Construction Phase
Construction typically happens in several stages:
- Foundation & Framing — Building the structural shell
- Rough-ins — Electrical, plumbing, HVAC systems are installed
- Insulation & Drywall — Interior walls go up
- Finishes — Flooring, cabinetry, paint, fixtures
- Exterior Work — Siding, roofing, landscaping
Inspections happen throughout the build to make sure everything is up to code.
6. Inspections & Final Approvals
- Your contractor will schedule and coordinate inspections for structural, electrical, plumbing, and other systems.
- Once all inspections pass, you’ll get final approval or a certificate of occupancy (or equivalent), making the ADU legally habitable.
7. Handoff & Move-In
- Final Walk-Through: You’ll walk through the completed ADU with your contractor. Any punch-list items (small fixes or adjustments) are identified and completed.
- Training & Maintenance Orientation: Fabrick will likely walk you through how to use your systems (HVAC, appliances) and advise on maintenance.
- Handoff: You get the keys — and often, a folder with warranty details, as-built plans, and permit documentation.
8. Post-Construction Support
- Warranty & Repairs: Fabrick typically offers a warranty period, so if anything goes wrong, they’re on it.
- Long-Term Maintenance: Whether it's a repair, remodel, or tenant turnover, your local contractor is nearby to help.
Why Choosing a Local San Diego Contractor Matters at Each Step
- Regulatory Expertise: They know San Diego’s ADU zoning, permitting timelines, and local inspection processes.
- Faster Permitting: Their familiarity with local permitting departments can speed up approvals.
- Better Cost Control: Local contractors have relationships with San Diego-based suppliers and subcontractors, which keeps costs more predictable.
- Efficient Communication: Face-to-face meetings are easier, and you benefit from real-time problem-solving.
- Long-Term Support: Local ADU builders are more accessible for maintenance, modifications, or future projects.
Common Pitfalls & Risks (and How a Trusted Contractor Helps Avoid Them)
- Underestimating the time for permit approvals — the process often takes 3–5 months.
- Overlooking local code requirements, such as coastal permits or septic system constraints.
- Choosing a contractor without ADU experience — ADUs have unique structural and utility needs
- Budget surprises due to change orders or unplanned site conditions
- Delays because of utility company coordination or inspection scheduling
A contractor with deep San Diego ADU experience (like Fabrick) helps you mitigate these risks.
