Del Mar Backyard ADU

A new backyard cottage built from slab to finish — sage-green siding, covered porch, and hardscape for a North County San Diego family.

Completed sage-green backyard ADU with covered porch in Del Mar by MA Properties

From slab to finish

MA Properties designed and built this accessory dwelling unit for a Del Mar homeowner who needed extra living space without leaving the neighborhood. Owner Gustavo Mello supervised the job from foundation through final walkthrough: concrete slab and rough-ins, structural framing, weather barrier and windows, then exterior finishes, porch, and site work. The result is a durable coastal cottage that matches the main home and is ready for guests or long-term use.

  • New backyard ADU from foundation to finish
  • Owner-supervised build with licensed crew (CSLB #1142409)
  • Coastal-ready exterior, porch, and site hardscape
  • Clear written scope before construction starts
