Home / Services / Accessory Dwelling Unit Construction San Diego
Accessory Dwelling Units (ADUs), also known as granny flats, in-law units, or backyard cottages, are secondary residential units built on the same lot as a primary residence. Due to updated zoning laws and housing demand, ADUs have gained popularity in California. They can be attached or detached structures and offer a versatile solution for homeowners seeking rental income, additional living space, or multigenerational housing.
As experienced accessory dwelling unit builders in San Diego, Ground Up Construction Management specializes in designing and constructing high-quality ADUs that meet local code, maximize your property’s potential, and enhance long-term value.
Many homeowners in San Diego are choosing to build ADUs for a variety of reasons:
Building an ADU without professional help can lead to costly mistakes and missed opportunities:
California has specific guidelines for accessory dwelling units; ignoring them can halt your project.
Incorrect documentation or unpermitted construction may delay approvals or trigger fines.
A poor layout can limit usability, appeal, and rental potential.
Delays in building mean delayed rental income or long-term financial benefits.
