Scope of ADU Construction Services


ADU construction requires careful planning to meet zoning, permitting, and design requirements. Velsa Home Builders provides comprehensive services for residential property owners seeking to add an independent living unit.

Detached ADUs

We design and build standalone units that offer privacy, flexibility, and modern design while adhering to local building regulations. Detached ADUs are ideal for rental income, guest accommodations, or extended family living.

Attached ADUs

Attached ADUs expand your existing home by creating additional living space connected to your main structure. Our team ensures that these additions integrate seamlessly with the home’s architecture and systems.

Interior and Garage Conversions

For properties with underutilized spaces, we provide interior or garage conversions to create functional ADUs. These solutions maximize space without altering your lot’s footprint.

Full ADU Project Management

From design to completion, we coordinate permits, utilities, foundations, framing, interior finishes, and inspections to deliver a fully functional and compliant living unit.

ADU Construction Process


Building an ADU involves detailed planning and execution to meet code, functionality, and aesthetic goals:

Consultation and Site Evaluation

We assess your property, zoning requirements, and ADU feasibility. A detailed plan is developed to ensure optimal placement, size, and design of the unit.

Design and Permitting

Our team prepares architectural plans and submits all necessary permits to local authorities in San Diego, CA and surrounding areas. This ensures compliance with zoning and building codes.

Site Preparation and Construction

We handle excavation, foundation, framing, roofing, and utility connections. Each step is carefully executed to ensure structural integrity and functionality.

Interior and Exterior Finishes

Cabinetry, flooring, fixtures, appliances, and exterior siding are installed according to design specifications. Every finish is completed to ensure durability, comfort, and aesthetic appeal.
