What is a tenant fit-out?
A tenant fit-out, also called a tenant improvement or build-out, is the work that turns an empty commercial space into one ready for a specific business: walls, ceilings, lighting, flooring, paint, restrooms and finishes. The lease usually spells out what the landlord pays for, often through an improvement allowance, and what the tenant covers.
Spaces are delivered in different conditions. A "shell" has bare structure and utilities; a "white box" or "vanilla shell" adds finished walls, a ceiling grid, basic lighting and restrooms; a turnkey fit-out is finished to the tenant's design. Knowing which one you're getting is the first line of the budget.
Can a commercial renovation be done after hours?
Yes. We regularly schedule demolition, drilling, sanding and other noisy or dusty work at night or on weekends, and do quieter work while the business is open. In occupied offices we phase the job by zone, with dust containment and a clean, safe path for staff and customers every morning.
After-hours work needs coordination with building management: access, alarms, elevator use, loading dock times and where the dumpster can sit. We set those rules in writing before the first night so nobody is surprised. Ahead of opening day, our crew does the post-construction cleaning so you don't need another vendor.
Do I need a permit and drawings for a commercial renovation in Massachusetts?
For most work beyond painting, flooring and similar finishes, yes. Commercial alterations under the Massachusetts State Building Code (780 CMR) generally need a building permit, and many require stamped drawings from a registered design professional. Electrical, plumbing, gas and fire-protection work each need their own permits pulled by licensed tradespeople.
Accessibility is the item that most often surprises owners. Alterations to public and commercial spaces fall under the Architectural Access Board regulations (521 CMR), and depending on the cost of the work and the value of the building, a renovation can trigger upgrades to an accessible entrance or restroom. Your architect and the building official determine that scope; we price it once it's known.
The Home Improvement Contractor (HIC) law covers owner-occupied homes, not commercial space, so for a commercial job ask for the contractor's certificate of insurance and check trade licenses on the state license lookup.
How much does a commercial fit-out cost?
It depends on scope more than square footage. Cushman & Wakefield's 2026 guide puts the average full office fit-out across the Americas at about $149 per square foot, and Boston-area costs rose sharply year over year, driven mostly by electrical work. A paint, flooring and ceiling refresh in a small office or store costs a fraction of that.
Electrical work is the largest single share of fit-out cost (about 24% in Cushman & Wakefield's data), so reusing existing lighting, outlets and circuits where the layout allows is one of the best ways to control the budget. Reusing ceiling grid, doors and restrooms helps too.
Which commercial projects does I&D Innovation take on?
Small and mid-size interior projects: office fit-outs and refreshes, retail and restaurant front-of-house renovations, medical and professional suites, salons, tenant turnovers and damage repairs in commercial units. Our crew does the demolition, framing, drywall, ceilings, carpentry, paint, flooring and cleaning, and licensed partners handle electrical, plumbing and fire protection.
Many MetroWest businesses only need part of that: a commercial painting job over a weekend, new LVT or vinyl plank flooring in a showroom, or new partitions for two more offices. We price each scope on its own, and a bilingual crew means owners, managers and staff can talk to us in English or Portuguese.
How the job works, step by step
- Site walk and scopeWe review the lease work letter, landlord construction rules, building hours, existing drawings and any finishes or equipment that stay, then walk the space with you or your property manager.
- Drawings and permitsMost commercial alterations beyond cosmetic finishes need construction documents from a registered architect or engineer. We work from those drawings, file the building permit, and licensed electricians, plumbers and fire-protection contractors pull their own trade permits.
- Schedule and phasingWe plan around your business: noisy and dusty work after hours or on weekends, phased zones in occupied offices, and a schedule shared every week with you and the landlord.
- Build-outSelective demolition, metal or wood stud partitions, drywall, acoustical ceiling grid and tile, doors and hardware, with licensed electrical, plumbing and sprinkler work coordinated in sequence.
- FinishesScrubbable commercial-grade paint, LVT or carpet tile, rubber base, millwork and signage backing, matched to your brand standards.
- Inspections, cleaning and handoverFinal inspections and any certificate of occupancy the town requires, punch list, and a post-construction cleaning so the space is ready to open.
