NNN vs Gross Lease Differences

Tenants and landlords in Rochester and Macomb County run into two lease types over and over, and mixing them up creates budget problems on both sides. A gross lease rolls almost everything into one rent check. The tenant pays a flat amount, and the landlord covers property taxes, insurance, and most building expenses from that rent. A triple net lease, usually written NNN, splits things. The tenant pays base rent plus a proportional share of property taxes, building insurance, and common area maintenance, commonly shortened to CAM.

The difference matters most when comparing asking rates. A $14 per square foot gross rate and a $10 per square foot NNN rate can end up very close once taxes, insurance, and CAM are layered in. In Macomb County, where property taxes can run $3 to $5 per foot on older industrial and CAM on multi tenant flex is often another $2 to $3, a cheap looking NNN rate can land above a gross deal once the charges are added up.

Retail in downtown Rochester and along Rochester Road tends to be NNN. Suburban office off Adams or Crooks often shows up as modified gross, where the landlord covers some items and the tenant covers others. Industrial in Warren, Sterling Heights, and Shelby Township runs the full range, with older multi tenant buildings leaning gross and newer single tenant properties almost always NNN.

For landlords, NNN leases pass building cost risk to the tenant, which is a big reason institutional buyers prefer them. If property taxes jump after a sale, which happens in Michigan because taxable value uncaps at transfer, the NNN structure shifts that increase to the tenant through the CAM reconciliation. Under a true gross lease, the landlord absorbs it and net income takes the hit. That is a real number in a market where a reset can push taxes up 30 percent overnight.

For tenants, a gross lease makes budgeting simple and protects against surprises. Utility spikes, a new roof, or a tax reassessment land on the landlord. An NNN lease can be cheaper in year one but creates exposure to any expense the building incurs. Tenants signing NNN deals need to ask about historical CAM, recent tax bills, upcoming capital work, and whether CAM is capped or uncapped.

TDG Commercial, known as some of the top commercial agents in Rochester MI, reads every lease carefully and models both structures before a client signs. Understanding NNN vs gross early changes the negotiation, often saving both sides money over the full term. Anyone considering space in the Rochester and Macomb County market should have both numbers side by side before committing.

A few specific items deserve extra attention during lease review. CAM caps protect tenants from runaway controllable expenses by limiting year over year increases, usually to 3 to 5 percent on controllable items. Non controllable items like property taxes, insurance, and snow removal typically stay uncapped because landlords cannot control them, and Michigan winters make snow removal a real line item. Audit rights let tenants verify the landlord’s CAM calculations, which matters on multi tenant buildings where small math errors multiply quickly across tenants.

Gross up clauses are another detail that hits NNN tenants when the building is not full. If a 100,000 square foot building is 60 percent occupied, the landlord’s fixed costs spread across fewer tenants. A gross up clause lets the landlord bill CAM as if the building were 95 percent occupied, protecting the landlord but sometimes surprising tenants. TDG Commercial flags these clauses in LOI review so tenants know what they are signing before the lease gets drafted, which avoids the much harder conversation of trying to change terms after the attorneys have already gone back and forth twice.
