Accessory Dwelling Units Custom & Prefab Solutions in CA

Introduction to Accessory Dwelling Units (ADUs)
As housing demands continue to rise, homeowners are looking for innovative ways to expand their living space and increase property value. One of the best solutions is an accessory dwelling unit (ADU). At Hernandez Family Construction, we specialize in designing and building high-quality accessory dwelling units that meet your needs and comply with local regulations.
An accessory dwelling unit, often referred to as a granny flat, in-law suite, or backyard cottage, is a self-contained residential unit located on the same property as a primary home. Whether you need additional space for family, rental income, or a home office, an ADU accessory dwelling unit is a smart investment.
Benefits of Accessory Dwelling Units
1. Increased Property Value
Adding an accessory dwelling unit enhances property value by providing additional functional living space. Future buyers find homes with accessory dwelling units more appealing, making them easier to sell at a higher price.
2. Rental Income Potential
Many homeowners turn their accessory dwelling unit into a rental property, generating passive income. Whether it’s a detached accessory dwelling unit or a garage accessory dwelling unit, renting an ADU can help offset mortgage payments and increase financial stability.
3. Multigenerational Living
With rising housing costs, many families prefer multigenerational living. An ADU accessory dwelling unit provides privacy while keeping loved ones close.
4. Sustainable and Affordable Housing Solution
An accessory dwelling unit is an eco-friendly alternative to traditional home expansions. Prefabricated options, such as a prefab accessory dwelling unit, minimize construction waste and reduce building costs.
Different Types of Accessory Dwelling Units
Detached Accessory Dwelling Unit
A detached accessory dwelling unit is a separate structure built on the same property as the primary residence. This type of accessory dwelling unit offers maximum privacy and flexibility, making it a popular choice for rental units or guest houses.
Garage Accessory Dwelling Unit
A garage accessory dwelling unit is an ADU that utilizes an existing or newly constructed garage space. This option is ideal for homeowners who want to maximize their property without additional land usage.
Prefab Accessory Dwelling Units
A prefab accessory dwelling unit is a pre-manufactured structure assembled on-site. These units come in various styles and sizes, providing an efficient and cost-effective housing solution.
