Lease Administration

You’ve Moved Into Your New Office: Now What?

Once you have negotiated your lease for your new or current space with your landlord, made your tenant improvements, and moved in, you might think you’re done. You can just settle into the next 5-7 years of your lease and just stick the document in the drawer, right?

Not quite.

Commercial leases are complicated, and your landlord is likely managing hundreds of tenants at once. Mistakes are common and costly for your business. One small honest error can cost you tens of thousands of dollars over the life of your lease. That’s where Mazirow Commercial comes in.

Where Lease Mistakes Happen

A typical lease is 30-80 pages long and a landlord has dozens or hundreds of tenants—that’s a lot of details to get right. You need to stay on top of every little detail, which is no mean feat when you’re also running a successful business. So where can those expensive mistakes creep in?

In the first year, or Base Year, of your lease, your landlord will use the year’s Operating Cost (OPEX) for the asset to establish the “base year” cost that all future year costs are compared against. (Costs like elevator maintenance, city taxes, and utilities.) Any increase over the Base Year OPEX is passed-through to tenants pursuant to their pro-rata share of space they occupy every year of their lease. OPEX is a standard in the market on a Full-Service Gross lease, which is the typical lease type for most office buildings. The OPEX is included in the cost of the base rent in the first year. You need to oversee and reconcile every cost to make sure it’s accurate, or you’ll wind up losing out on costs over the lifetime of your lease term.


  • It cost $12.00/Rentable Square Footage (RSF) annually to run the building
  • $12.00 is the Base Year
  • The building is 80,000 RSF in round numbers
  • It cost the Landlord 80,000 X $12.00 = $960,000.00/yr
  • Cost increase across the board (no likely) increase by 1.5%
  • $960,000.00 x .015 = $14,400/yr or $1200.00 a month
  • Your practice occupies 1.42% of the asset
  • 1.42% of $14,400.00 = $200.00 for the year of $16.59/month

And each year, you’ll need to track your operating expenses to ensure no errors and overcharges creep in. After all, your landlord is managing many other buildings—sometimes mistakes are made. A billing error of $250 per month might sound very small when you consider the high costs of commercial real estate. But over a five-year lease term, that little billing mistake would cost you $15,000. And you have better things to do with that money than overpaying your landlord.

Parking agreements can cause real headaches too. The mix of space options, rights, obligations, and tandem vs. single spots—it’s a lot to manage. Paying too much for parking that you’re not using adds significant costs to your lease without any benefit to you.

Also consider an Estoppel, which is a 1-2 page summary of the key terms outlined in your 30-80 page lease that your landlord will need you to sign. Your Estoppel may have mistakes. If you inadvertently sign away one of your rights as a tenant in an Estoppel, that mistake is set in stone. For example, if a tenant signed an Estoppel that ruled they had to pay $15,000 in property taxes, and they failed to do so for 3 years, their mistake would amount to $45,000.
