Most retail tenants in NYC focus on the base rent number. The base rent is not your real occupancy cost. The lease type is. Pick the wrong structure and you can end up paying $10 to $25 more per square foot than the rent on the LOI suggests.
Here is how net leases and gross leases actually work in NYC retail. And what you should actually negotiate.
Gross lease: one number, mostly
In a gross lease, the landlord pays property taxes, building insurance, and most building maintenance. The tenant pays one base rent figure. You still pay for your own utilities and your own interior maintenance. But the big building costs are on the landlord side.
Gross leases are more common in older Manhattan office buildings than in retail. In retail, true gross leases are rare. What landlords sometimes call gross is more often modified gross. Read the fine print.
Net lease: base rent plus your share of building expenses
In a net lease, you pay base rent plus a proportional share of the building's real estate taxes, insurance, and common area maintenance. The shorthand is NNN. Triple net. You pay all three.
On an older NYC building with high real estate taxes, the passthroughs can add up fast. I have seen NNN charges run $15 to $25 per square foot on top of base rent. That is a 10 to 15 percent swing on your occupancy cost.
The math gets worse over time. Real estate taxes go up every year in NYC. Your share goes up with them. The base rent escalation is the headline number. The tax passthrough is the silent one.
Modified gross: the most common NYC retail structure
Most NYC retail leases land somewhere in between. The tenant pays base rent and a percentage of any tax increase above a base year. The base year matters. A 2026 base year is much better than a 2018 base year if you are signing today.
Common area maintenance might or might not be included. Insurance might be passed through. The exact mix is negotiable.
What to actually negotiate
Three things. First, get the last three years of actual operating expense and tax history. Not the budget. The actual. Your broker should pull these. If they cannot, ask the landlord for them in writing.
Second, negotiate the base year. The base year sets your zero point for passthroughs. A current base year limits your exposure to historical tax increases.
Third, cap the controllable expenses. Common area maintenance, management fees, and other operating expenses should have a cap on year over year increases. Real estate taxes are usually uncapped because they are non-controllable. CAM should not be.
The bottom line
The base rent on your LOI is incomplete. Calculate your full occupancy cost. Base rent plus passthroughs plus utilities plus your share of insurance. That is the number to compare across spaces. Two LOIs with the same base rent can have $20 per square foot of difference in total cost.
Most of the lease terms tenants get burned on are not the headline economics. They are the structural terms that determine what the headline economics actually mean over the life of the lease.
