Understanding Martinez ADU Regulations and Permitting
Before breaking ground on an accessory dwelling unit in Martinez, homeowners and contractors must navigate the city's specific zoning and building codes. Martinez follows California state ADU law while also enforcing its own local guidelines. Key regulatory considerations include:

- Setback requirements: A minimum 4-foot rear and side setback is required for most new detached ADUs.
- Historic district considerations: Some areas of Martinez fall within historic overlay zones, requiring additional design review to preserve the city's architectural character.
- Parking requirements: In many cases, replacement parking is not required when a garage is converted into an ADU.
