Why Build an ADU in California?

Accessory Dwelling Units (ADUs) have become increasingly popular in California due to rising housing costs, the need for multi-generational living, and the potential for rental income. Whether you’re looking for additional dwelling unit plans for a detached backyard cottage, a modern accessory dwelling unit, or a garage conversion ADU, Hernandez Family Construction provides expert design and construction services.

Key Benefits of Building an ADU

• Increased Property Value: Adding an ADU boosts your home’s resale value.
• Rental Income: Generate passive income by renting out the unit.
• Multi-Generational Living: Perfect for aging parents, adult children, or guests.
• Affordable Housing Solution: Affordable ADU builders like Hernandez Family Construction make it cost-effective.
• Flexible Space Usage: Can serve as a home office, studio, or guest house.

Types of ADU Plans Available

When planning an ADU, you have several design options. Here are the most popular accessory dwelling unit plans:

Detached ADU Plans

A standalone structure built in your backyard, offering full privacy. Ideal for rental units or guest houses.

Best for: Homeowners with extra yard space who want a separate living area.

Garage Conversion ADU Plans

Converting a garage to an ADU in California is one of the most cost-effective ways to add living space. Since the structure already exists, construction costs are lower than building new.

Best for: Homeowners who want a quick, budget-friendly ADU solution.

Attached ADU Plans

An extension of your primary home, often designed as a basement or side-unit ADU.

Best for: Families who need extra space connected to the main house.

ADU Over Garage Plans

If you have a detached garage, you can build an accessory dwelling unit over garage plans to maximize space. These 2 story ADU plans are great for small lots.

Best for: Properties with limited yard space but high ceilings in existing garages.

Junior ADU (JADU) Plans

A smaller ADU (up to 500 sq. ft.) created within the existing home, such as a converted bedroom or basement.

Best for: Homeowners who need a compact living space without major construction.
