Interior Fit-Outs Explained
An interior fit-out converts an unfinished or vacant interior into a finished, tailored environment ready for its intended use.
The process includes installing partitions, flooring, ceilings, lighting, HVAC, plumbing, finishes, and sometimes built-ins. A fit-out not only makes a space functional but also visually appealing and code-compliant.
Fit-outs are typically classified into:
- Shell and Core Fit-Outs – Interior completion within an existing structural shell, including HVAC, plumbing, and electrical systems.
- Category A – Delivers a basic finished space with floors, ceilings, lighting, and fire suppression—ready for tenant customization.
- Category B – Fully customized interiors with branding, room layouts, furniture, and operational spaces.
All fit-outs must meet the Massachusetts State Building Code (780 CMR) for accessibility, energy efficiency, and safety: mass.gov
