A typical dental office build-out takes between 12 to 16 weeks of actual construction time. However, the pre-construction phase can add another 8-12 weeks. Understanding this timeline is crucial for managing your lease negotiations and marketing strategy.

Phase 1: Design & Permitting (Weeks 1-8)

This phase happens before hammers swing. It's the most critical period for cost control.

Key Milestones
  • Space Planning: Determining number of operatories and sterilization layout.
  • Equipment Selection: Choosing chairs and delivery units (critical for plumbing locations).
  • Permitting: Submitting MEP drawings to the city.

Phase 2: Demolition & Rough-In (Weeks 9-12)

Construction begins. The space is cleared, and the complex infrastructure is installed.

  • Under-Slab Plumbing: Trenching for water, air, and vacuum lines to each dental chair.
  • Framing: Walls go up, defining the rooms.
  • Medical Gas Rough-In: Nitrous and oxygen lines are run behind walls.

Phase 3: Drywall & Finishes (Weeks 13-16)

The office starts to look like a practice. Walls are closed, painted, and flooring goes down.

  • Backing Installation: Strategic wood blocking in walls to support heavy X-ray arms and cabinets.
  • Cabinetry: Sterilization centers and operatory cabinets are installed.

Phase 4: Equipment Installation (Weeks 17-19)

Your dental dealer installs the specialized technology.

This is where coordination between the General Contractor and the Equipment Supplier is vital. Water, air, and electric connections must match the template exactly.

Phase 5: Inspections & Turnover (Week 20)

Final city inspections, punch list completion, and certificate of occupancy.
