Additionally, this stage addresses specific site requirements essential for the construction process.
  • Underground Utilities: This phase involves installing essential services like water, sewage, and electrical lines beneath the ground at your ADU construction site. This step is critical as it ensures that your ADU will have access to vital utilities.

  • MEPs: The MEP (Mechanical, Electrical, and Plumbing) phase is essential in ADU construction. It involves installing heating, ventilation, and air conditioning systems for climate control, setting up electrical wiring and lighting, and establishing plumbing for water supply, drainage, and sewage.
  • Interior & Exterior Finishes: The Interior and exterior finishes phase brings your ADU to life. It includes adding final indoor aesthetic touches and landscaping/hardscaping to enhance your ADU’s visual identity and functionality.
  • Final inspection: During the final inspection phase, local authorities conduct thorough assessments to verify your ADU’s compliance with safety codes, zoning regulations, and quality standards.
