Common questions

What are the rules for ADUs in California?

California has state-mandated ADU laws that set minimum standards, but local jurisdictions can have their own specific requirements. These often involve size limits, setback rules, and parking provisions. We help you navigate both state and local rules for your ADU project in California.

Is there a grant for ADUs in California?

While there haven't been consistent statewide grant programs for ADUs, some local programs or financing options may exist. We can explore potential avenues for financial assistance or favorable financing for your ADU project in California. Our focus is on making your ADU achievable.

How big can an ADU be in California?

California law generally allows ADUs up to 1,200 square feet, or 800 square feet for an ADU that is 16 feet or taller, and typically limits them to 10-foot setbacks. Specific local ordinances can also apply. We ensure your ADU design complies with these size regulations in cities like Fresno.

What types of homes are best for ADUs in California?

Many single-family homes with adequate yard space in California are ideal for ADUs. This includes properties in areas like Long Beach, Fremont, and San Bernardino. We assess your existing home and lot to determine the best placement and design for your accessory dwelling unit.

How do I get permits for an ADU in Fontana?

Permitting an ADU in Fontana involves submitting plans that comply with both state ADU laws and Fontana's specific zoning and building codes. We manage the design and documentation process to meet these requirements. This ensures your ADU project in Fontana moves forward smoothly.

What are the zoning requirements for ADUs in Los Angeles County?

While Los Angeles County has its own set of ordinances, many cities within the county, like Long Beach, have specific ADU rules. These typically involve lot size, setbacks, and parking. We help you understand and comply with the relevant zoning requirements for your ADU.
