Planning to customize a commercial space for your business or tenant?

That’s called a tenant fit-out, and it’s one of the most important steps in making a new or existing commercial unit functional, compliant, and move-in ready.

Whether you’re a landlord preparing for a new tenant or a business owner building out a leased space, understanding what goes into the process can help avoid delays and costly surprises.

What Is a Tenant Fit-Out?

A tenant fit-out (or tenant improvement) is the process of customizing the interior of a commercial space to meet a tenant’s specific needs.

This often takes place in a “white box” or “shell condition” space, where only the basic structure exists.

Fit-outs can range from minor upgrades (new walls and finishes) to full-scale construction including HVAC, plumbing, fire suppression, and electrical systems.

Phase 1: Planning & Permitting

The first step is understanding:

  • The tenant’s space and operational needs
  • Building code and ADA compliance
  • Local permitting requirements
  • Budget and timeline goals

This phase may involve:

  • Architectural drawings
  • Engineering plans
  • Coordination with the building owner and town officials

Pro Tip: Cities in MA and NH often have strict rules for fire safety, accessibility, and mechanical systems — working with a contractor who knows the local landscape is key.

Phase 2: Demolition & Prep Work

If the space isn’t brand new, selective demo of old finishes, walls, ceilings, and utilities may be required.

We also assess existing infrastructure to make sure it can support the tenant’s design.

Phase 3: Framing, MEP Rough-Ins & Utilities

We install:

  • Metal or wood framing for new walls and rooms
  • Mechanical (HVAC), Electrical, and Plumbing (MEP) systems
  • New sprinkler heads or fire alarm devices if needed

All this is inspected before drywall goes up.

Phase 4: Insulation, Drywall & Finishes

Once rough-ins pass inspection, we close up the walls and install:

  • Drywall and ceiling systems
  • Interior doors
  • Paint, trim, and flooring
  • Cabinetry or specialty millwork if needed

Phase 5: Final Electrical, Fixtures & Walkthrough

We install:

  • Light fixtures, outlets, switches
  • HVAC diffusers and controls
  • Bathroom fixtures, kitchenettes, signage
  • Emergency exit and fire system equipment

Then we walk through with the client for punch list items and schedule the final inspection.

  • Clear communication between tenant, landlord, architect, and GC
  • Accurate scheduling and permitting

  • Code compliance every step of the way
