Second Story ADU Services
A second story ADU is built above an existing structure - typically a garage or a new first-floor footprint - giving homeowners the ability to add a dwelling unit without consuming any additional lot area. This is the ideal solution for properties where setback requirements, small lot size, or existing structures leave little room for a ground-level ADU.
CCS Inc. designs and builds second story ADUs that are structurally sound, architecturally complementary to the existing home, and compliant with all height limits and setback regulations. Our structural engineers conduct thorough load analysis to determine whether the existing structure (often a garage) can support a second story, or whether reinforcement is needed.
Under California ADU law, second story ADUs are permitted up to 16 feet in height on most residential lots, and cities cannot impose design review or discretionary approval for ADUs that comply with state standards. CCS has built dozens of second story ADUs across Los Angeles, frequently building above existing garages to create spacious one-bedroom or two-bedroom units with excellent natural light and views.
Key Highlights
- Zero additional lot coverage - build above existing structures
- Ideal for small lots with limited ground-level space
- Often built above garages, preserving parking and yard
