What does an office renovation cost per square foot?

Commercial office work in the Capital Region generally falls into three bands. A cosmetic refresh — paint, carpet, lighting swaps, minor patching — runs roughly $25 to $50 per square foot. A standard fit-out that moves walls, reworks power and data, and replaces ceilings and flooring typically lands between $65 and $130. A full gut with new mechanical distribution, upgraded electrical service, and custom millwork can pass $200.

The spread is wide because "office renovation" describes everything from new carpet to a new building interior. Before comparing any two quotes, establish which band you are actually in.

What drives the price up the most?

Four line items move a budget more than finishes ever will:

Mechanical. If the layout changes, ductwork and diffusers change with it. Adding conference rooms to an open floor often means new zoning and controls, not just more supply.
Electrical service. Adding dedicated circuits, a server room, or EV-adjacent loads can push you past the existing panel capacity. A service upgrade is a utility coordination item, not a one-week task.
Fire protection. Move a wall and the sprinkler heads below the ceiling have to move too. Every new room needs proper coverage.
Accessibility compliance. Renovations above certain thresholds trigger upgrades to restrooms, door hardware and path of travel. This surprises people and it is not optional.

Flooring and paint are the visible costs and among the smallest.

What is a tenant improvement allowance and who controls it?

A tenant improvement allowance is money the landlord contributes toward building out your space, usually expressed per square foot and negotiated into the lease. In the Capital Region, allowances on multi-year commercial leases commonly run in the $20 to $60 per square foot range, though it varies heavily by building class and lease length.

Two details matter more than the headline figure. First, whether it is paid as a reimbursement after completion or drawn during construction — reimbursement means you finance the job. Second, what it can be spent on. Many allowances exclude furniture, cabling and anything removable, which is exactly where tenants assume they can spend it.

Should I renovate or relocate?

Run the comparison on total cost, not construction cost. Relocating adds moving expenses, new cabling and AV, downtime, signage, address changes, and usually a higher rent per square foot in a newer building. Renovating in place adds the cost of working around your staff, or temporary space if you cannot.

The practical test is whether the existing building's bones work. If the floor plate, ceiling height, column spacing and mechanical capacity suit how you want to operate, renovating is almost always cheaper. If you are fighting the structure to get the layout you need, you are paying a premium to stay.

Can we stay in the space during construction?

Often yes, in phases — but phasing costs money. Splitting a floor into two or three construction zones means mobilizing trades more than once, building temporary partitions, and doing noisy work outside business hours. Expect a phased occupied renovation to add somewhere around 15% to 25% over the same scope in an empty space, and to run longer.

It is frequently still the right answer. Paying a phasing premium beats paying six months of rent on a swing space.

How much contingency should be in the budget?

For a renovation in an existing building, 10% to 15% is realistic, and closer to 15% in an older structure. Renovation contingency is not padding — it covers what you find after demolition opens the walls: undocumented conditions, abandoned utilities, framing that does not match the drawings, and in older Capital Region buildings, materials that need proper abatement.

A contractor who proposes 3% contingency on a 1960s building is either very familiar with that specific property or is going to be issuing change orders.

What should be settled before pricing?

A test fit or space plan showing room counts and sizes
Finish level — building standard or upgraded
Whether mechanical and electrical distribution is being reused or replaced
Your occupancy date, and whether it is genuinely fixed
Who is buying furniture, AV and cabling: you or the contractor

Without those five, any number you receive is a guess dressed as an estimate.

Where to start

Get a test fit done before you get pricing. A space planner can usually tell you within a week whether your headcount and room requirements actually fit the floor — and that single document turns three incomparable quotes into three numbers you can hold side by side.
