How Commercial Leases & NNN Rates Work in Northern Colorado
Understand the lease structures, pass-through expenses, and asset-class norms that shape commercial rent across Weld and Larimer Counties.
Base Rent vs. NNN (Triple Net) Charges
Commercial leases across Greeley and Fort Collins are most often quoted in dollars per square foot per year ($/SF/Yr). The Base Rent is the contractual rent for the space itself; the Triple Net (NNN) pass-through reimburses the landlord for the tenant's pro-rata share of Property Taxes, Building Insurance, and Common Area Maintenance (CAM). On the calculator above, Base Rent and Est. NNN are added together to show your true monthly occupancy cost — the number that actually hits your P&L.
Typical NNN Ranges by Asset Class in NoCo
Pass-through structures vary by asset class. Flex Industrial & Yard Space along the Highway 85 Industrial Corridor typically carries lower NNN ($2.50–$4.50/SF) because CAM is light and tenants maintain their own bays. West 10th Street Retail Corridor storefronts run higher ($4.50–$7.00/SF) due to shared parking, landscaping, and signage upkeep. Professional Office space often lands between ($4.00–$6.50/SF) with full-service or modified-gross structures that bundle utilities and common-area janitorial into a single monthly figure.
Gross vs. Modified Gross vs. Triple Net
A Gross lease bundles all operating costs into one rent payment — common for smaller office suites and turnkey spaces. A Modified Gross lease splits out one or two cost categories (often utilities or janitorial) while keeping the rest in base rent. A Triple Net (NNN) lease pushes Property Taxes, Insurance, and CAM to the tenant as a monthly pass-through. For contractors, fleet operators, and retail storefronts in Weld County, NNN is the prevailing structure for yard and storefront space because it keeps base rent low and gives the tenant direct control over the operating costs they actually drive.
What to Know Before You Sign in NoCo
- Always underwrite the all-in number. Base Rent + NNN is your real monthly cost — not the quoted $/SF/Yr.
- Confirm what NNN includes. Ask for the landlord's CAM reconciliation so taxes, insurance, and maintenance are itemized.
- Match the structure to the use. Contractors and fleet operators usually benefit from NNN yard space; office users often prefer gross or modified-gross suites.
