Steps to Build an ADU in Los Angeles: Your Complete Guide
Building an Accessory Dwelling Unit (ADU) in Los Angeles is one of the smartest ways to add value, flexibility, and income potential to your property. But navigating the design, permitting, and construction process can feel overwhelming without the right team. At Pacific Point Builders, we specialize in turnkey ADU solutions, managing every step from concept to completion.
Here’s a clear breakdown of the process to help you understand what it takes to bring your ADU to life in Los Angeles.
Step 1: Site Evaluation & Feasibility Study
Before you start designing, it’s essential to confirm that your property qualifies for an ADU.
- Review zoning, setbacks, and utility locations.
- Measure available space for your unit and determine if a garage conversion, attached, or detached ADU fits best.
- Identify potential challenges like slope, easements, or utility connections.
✅ Pacific Point Builders provides free consultations and feasibility checks to help you start with confidence.
Step 2: ADU Design & Planning
Once feasibility is confirmed, the design phase begins.
- Work with your design team to create a layout that fits your goals — whether it’s a rental unit, guest suite, or home office.
- Prepare architectural drawings, structural engineering, energy calculations (Title 24), and site plans.
- Make early selections for finishes and materials to align with your budget.
✅ Our in-house design team specializes in maximizing small spaces while maintaining high-end comfort and style.
Step 3: Permitting with LADBS or LA County
Permitting is often the most time-consuming part of the process — but we handle it for you.
- Submit plans to the Los Angeles Department of Building and Safety (LADBS) or your city’s building department.
- Address plan check comments, make revisions, and secure all necessary permits.
- Obtain approvals for building, plumbing, electrical, mechanical, and energy compliance.
✅ We coordinate directly with LADBS to streamline approvals and save you time.
Step 4: Sitework & Foundation
Once permits are approved, construction begins with groundwork.
- Demolition (if converting or removing an existing structure).
- Grading, trenching for utilities, and pouring the foundation or slab.
- Inspection and approval from city inspectors before framing begins.
✅ Our crews ensure the foundation is solid, level, and ready for long-term durability.
Step 5: Framing & Rough Construction
Your ADU starts taking shape as the structure goes up.
- Framing walls, roof, and openings for doors and windows.
- Installation of rough plumbing, electrical, and HVAC systems.
- Passing mechanical, electrical, and plumbing (MEP) inspections.
✅ We focus on precision framing and code compliance at every step.
Step 6: Insulation, Drywall & Finishes
Now the interior transformation begins.
- Insulation for comfort and energy efficiency.
- Drywall, painting, flooring, cabinetry, tile, and lighting.
- Installation of windows, doors, appliances, and fixtures.
✅ Our interior design team helps you choose finishes that match your vision and budget.
Step 7: Final Inspection & Certificate of Occupancy
After the last details are complete, the city conducts final inspections.
- Verify that all systems are safe and compliant.
- Approve the Certificate of Occupancy (CofO).
- Your new ADU is officially ready to use or rent!
✅ We walk you through the final inspection process and ensure every box is checked.
Step 8: Move In or Rent Out
Once you receive your CofO, you can start enjoying your new space.
- Use it as a guest home, private office, or rental for extra income.
- Many homeowners recover their investment quickly through rental revenue.
✅ Pacific Point Builders delivers turnkey, move-in-ready ADUs built to last.
