What Is an Office Renovation?
An office renovation rebuilds an existing workspace: new layout, partitions, ceilings, lighting, flooring, electrical and data, meeting rooms, reception and washrooms. A fit-out is the same work applied to a shell or second-generation unit you have just leased, turning bare space into a working office. Deomax handles both as an office renovation contractor across Toronto and the GTA, managing drawings, permits, trades, inspections and turnover under one contract.
Office fit-out scope: what each level actually includes
| Level | Typical scope | Usually needs a permit? | Business impact |
| Cosmetic refresh | Paint, flooring, ceiling tile, light fixture swaps, reception facelift. No layout change. | Usually not | Can normally be done after hours and on weekends with the office staying open |
| Reconfiguration | New partitions and demising walls, meeting rooms and phone rooms, added circuits and data, relocated lighting, HVAC diffuser changes. | Usually yes | Phased zone by zone so staff relocate within the floor rather than leaving |
| Full fit-out or build-out | Shell or gutted unit: full framing, electrical and data, plumbing, HVAC distribution, ceilings, washrooms, kitchenette, millwork, reception, accessibility. | Yes | Done before occupancy, so no downtime, but drawings, permit and lead times set the move-in date |
| Change of use | Converting retail, industrial or other space into office use. | Yes, plus zoning review | Longest approval path, confirm feasibility before signing the lease |
Keeping the office running: downtime and phasing
Most office clients cannot close. The plan we build around that has four parts:
- Zoning the floor. We split the office into work zones and hoard them off, so construction never shares air or a corridor with staff. Staff move once, not repeatedly.
- Out-of-hours for the loud and dirty work. Demolition, core drilling, anchor work and anything that trips fire alarms is scheduled evenings or weekends, agreed with the property manager in advance.
- Service shutdowns booked, not sprung. Power, data, sprinkler and HVAC shutdowns are identified at scope stage and calendared with your IT and the building, so nobody loses a trading day unexpectedly.
- Dust and life-safety control. Negative-air and floor protection in the work zone, plus fire-alarm isolation coordinated with the building so a construction shutdown does not evacuate the tower.
Where a phase genuinely cannot be done around you, we say so at scope stage and give you the date range, rather than discovering it mid-build.
