Step 1: Initial Consultation and Planning – This is where you discuss your vision with a licensed contractor. They'll assess your garage's suitability, discuss your goals, and outline potential designs and layouts. This usually takes a few weeks to solidify the concept.
Step 2: Design and Architectural Drawings – Once the concept is clear, architects and designers will create detailed plans that meet your aesthetic and functional needs, ensuring compliance with local building codes. This phase can take several weeks to a couple of months, depending on complexity.
Step 3: Permitting and Approvals – Your contractor will submit the architectural plans to the local Los Angeles building department for approval. This can be a lengthy process, often taking a few months, but a knowledgeable builder can help navigate it efficiently.
Step 4: Site Preparation and Demolition – After permits are secured, the construction begins. This involves clearing out the garage, any necessary demolition of existing structures, and preparing the foundation for the new ADU. This typically takes a week or two.
Step 5: Framing, Rough-Ins, and Exterior Work – The structure takes shape during this phase. Framing for walls, windows, and doors goes up, and plumbing, electrical, and HVAC systems are installed. Exterior siding and roofing are also completed. This is a major phase, lasting several weeks.
Step 6: Interior Finishes – This is when your ADU really starts to feel like a home. Drywall, flooring, cabinets, paint, and fixtures are installed. This phase requires careful coordination and can take a few weeks to a month.
Step 7: Final Inspections and Walkthrough – Once construction is complete, a final inspection is performed by the city to ensure everything meets code. After passing, your contractor will do a final walkthrough with you to address any last details. This typically takes a week or two.
