Types of ADU Projects They Handle
Prominent Builders & Restoration offers a range of accessory dwelling unit services to suit different property types and homeowner goals:
- Detached ADU Construction — Standalone backyard homes designed to provide independent living spaces, functioning as a separate unit on the same property.
- Garage Conversion Contractor Services — Transforming unused garage space into fully functional living units, a practical option for properties with existing structures.
- Attached ADU Units — Integrated home extensions that expand residential living space while remaining connected to the primary dwelling.
- ADU Design & Planning — Professional design and planning services to ensure compliance with local building codes and zoning requirements.
- Construction Management — Complete project oversight from planning through final inspection.
- Turnkey ADU Projects — Full-service construction delivering move-in ready backyard homes.
Whether the goal is to build a granny flat, a detached ADU, or convert an existing garage, the team at Prominent Builders & Restoration handles the process with professional project management and quality materials.
The ADU Construction Process
Prominent Builders & Restoration follows a structured five-step process for ADU projects:
- Consultation — The team evaluates the property, discusses ADU goals, and reviews zoning and feasibility.
- Design & Planning — Architectural plans, permits, and construction timelines are developed.
- Pre-Construction — Material selections are finalized, permits are secured, and the site is prepared.
- Construction — The ADU is built using quality materials and experienced craftsmanship.
- Final Inspection — The completed unit is reviewed to ensure it meets all building regulations and quality standards before handover.
ADU construction timelines typically range between 4 to 8 months from the start of design to final inspection, depending on the size and complexity of the project.
Prominent Builders & Restoration currently serves homeowners across San Diego — including areas such as La Jolla, Del Mar, Carlsbad, Chula Vista, Mission Valley, Coronado, and North Park — and works with property owners throughout California. The company is also preparing to expand its construction services across the United States.
California law broadly supports ADU development to address housing shortages, and many properties in San Diego are eligible to build accessory dwelling units through a streamlined permitting process. An ADU, or accessory dwelling unit, is a secondary residential unit built on the same property as a primary home — whether as a detached structure, an attached addition, or a garage conversion.
