San Diego Details Seven Required Plans for Garage Conversion ADUs
San Diego's Development Services Department (DSD) mandates seven specific plans for homeowners undertaking garage conversion Accessory Dwelling Units (ADUs). These plans are crucial for ensuring the converted structures meet residential standards for habitability, safety, and energy use, despite the existing walls, roof, and slab. The required documentation includes existing conditions and as-built drawings, a site plan, floor plans (both existing and proposed), exterior elevations and building sections, structural and foundation details, electrical, plumbing, and mechanical plans, and Title 24 energy compliance and code notes. The DSD reviews these plans to confirm accurate representation of the existing structure, proposed changes, and compliance with building codes. Incomplete or inaccurate drawings are a primary cause for delays in the approval process.
