ADU Regulations in Morgan Hill
Morgan Hill follows California’s state ADU standards but has its own local guidelines for single-family and multi-family lots.
For single-family properties, homeowners can build one detached or attached ADU and one Junior ADU (JADU). Detached ADUs can be up to 1,200 square feet, while attached ADUs may not exceed 50 percent of the primary dwelling, with 1-bedroom units up to 900 square feet and 2-bedroom units up to 1,000 square feet. JADUs are capped at 500 square feet. Setbacks are generally four feet from the side and rear, and height limits are 16 feet for single-story detached ADUs.
On multi-family properties, owners may build up to two detached or attached ADUs, with each unit not exceeding 25 percent of the existing dwelling units or one unit, whichever is smaller. Setbacks and height limits follow the same rules as single-family lots.
These standards provide flexibility while maximizing property use and income potential, making ADUs a practical and accessible option for many Morgan Hill homeowners.
The Morgan Hill ADU Permitting Process
Getting an ADU permit in Morgan Hill begins with confirming your property is zoned residential and meets setback, lot size, and ADU type requirements. Homeowners then prepare a full set of plans, including site, architectural, structural, energy (Title 24), and utility load documentation, following the city’s ADU checklist. Applications are submitted in PDF form via email and permit review typically completes within 60 days, with faster turnaround possible when using approved ADU designs.
Once the permit is approved, construction can begin, and inspections are scheduled via the eTRakit system. After passing all required inspections, homeowners receive a final certificate of occupancy, city submission, and approvals to ensure a smooth, compliant ADU project from start to finish.
