If your team is one to eight people and you need space in Kingston soon, a furnished office on a short agreement will often cost less in year one than a conventional lease, because you skip the fit-out, the furniture, the utility accounts and the five-year commitment. A conventional lease starts to win when your team is larger, your plans are fixed for five years or more, and you want to design the space yourself. The rest of this post shows how to run the numbers for your own situation, so you are comparing the full cost of each option and not just the rent on the listing. Our own furnished offices, KEILTY Workspace at 863 Princess Street, open in October 2026, and we use their published rates as the example.
The short version.
A conventional office lease is priced per square foot, per year. The number on the listing is the net rent. On a net lease, you also pay additional rent: your share of the building's property taxes, insurance and common area maintenance. Landlords sometimes call this TMI. It is quoted separately and it can move from year to year as the building's costs change.
Then there are the costs that never appear on the listing:
None of this makes a conventional lease a bad choice. For an established firm with a stable headcount, a long lease gives you control over the space and a known base rent for years. It simply means the rent on the listing is the start of the calculation, not the end of it.
A furnished private office is a lockable office inside a shared, professionally run suite. You pay one monthly fee, and the operator provides the furniture, the internet, the utilities, the common areas and the building relationship. You bring your laptop.
At KEILTY Workspace, our furnished offices at 863 Princess Street, Suite 301 include furniture, high-speed Wi-Fi, heat, hydro and air conditioning, weekly cleaning of the common areas, reception and mail handling, a shared kitchen, 24/7 fob access, four meeting room hours a month and one free on-site parking space per office. Our published rates run from $455 a month for a compact single-person office to $1,830 a month for a corner office that fits three or four people, all plus HST. The current rates are listed on our furnished offices in Kingston page.
What you give up is control over the layout. You cannot move walls, and you share the kitchen, the meeting room and the reception area with other members. For a team of one to eight people, that trade can be worth making, using a team suite of adjoining offices for teams larger than four.
Convert both options into one number: your all-in cost per month over the period you actually expect to need the space. Here is the arithmetic for a conventional lease.
For a furnished office, the calculation is shorter: the monthly fee, plus any extra services you would buy, such as additional meeting room time or coffee service.
Now run a worked illustration. The figures below are round numbers chosen to show the method; they are not a quote for any building, and you should replace every one with the numbers from the listings and quotes in front of you. Say a two-person firm looks at a 600 square foot suite at $15 net plus $13 additional rent. That is $28 a square foot, or $16,800 a year, which is $1,400 a month before anything else. Add $250 a month for hydro, internet, cleaning and insurance. Add $30,000 of fit-out and furniture spread over the 60 months of a five-year term, which is $500 a month. The all-in figure is about $2,150 a month, and the firm has committed for the full five years.
The same two people in a KEILTY Workspace window office pay $725 a month plus HST, with parking for one car included, on a 3-month minimum. Two people who want more room could take a large office at $1,035 a month. The illustration is not the point. The point is that the costs outside the rent can add a large share on top of the listing figure, so compare all-in numbers only.
Four items catch people out.
Often more than the rent. A conventional office lease runs for a fixed term of several years, and you are responsible for the rent for the whole term even if your plans change. Landlords will also look at your financial statements and may ask for a personal covenant from the owners of a small company. If the business moves, shrinks or is sold, you may be negotiating a sublease or an assignment.
A furnished office agreement is shorter and simpler. At KEILTY Workspace the minimum is three months, then month to month. After the first three months, either side can end the agreement on 30 days' notice. The deposit is one month's fee plus HST, applied to your final month's fees. That flexibility has real value if your headcount is uncertain, if you are waiting for a longer-term space to be ready, or if you are testing Kingston as a new market.
Choose a conventional lease when most of these are true:
KEILTY also manages conventional office space for lease. If your needs fit that list, see our office space for lease page and tell us what you need.
A furnished office tends to fit when:
Teams that need two or more offices side by side can take a team suite, which is priced at the combined rate of the offices less 10%.
Whichever route you take, ask these questions in writing and keep the answers with the agreement.
At KEILTY Workspace the fee increases by a fixed 3% on each anniversary, so there is no index calculation to follow. Our answers on cost, term, notice, deposit, increases, parking and access are published on our furnished offices page, and you can see the monthly total, HST and deposit for any office on our get started form before you commit to anything.
For a team of one to eight people it is often cheaper in the first year or two, because the monthly fee includes furniture, internet, utilities and common areas that a conventional lease leaves to you. For a larger team with settled plans over five years or more, a conventional lease can cost less per person.
Additional rent is the tenant's share of the building's property taxes, insurance and common area maintenance, charged on top of the net rent on a net lease. It is quoted per square foot per year and can change as the building's costs change.
Three months, then month to month. After the first three months, either side can end the agreement on 30 days' notice. Your first month is free on a 3-month agreement.
Yes. A furnished office works well while your headcount settles, and you can sign a longer lease when you are ready. Because KEILTY also manages conventional office space for lease, we can talk through both options with you.
