Commercial space for lease in Longmont: a tenant's guide.
Longmont is the deepest commercial market in our corridor, which means more options and more ways to pick the wrong one. Here is how the city breaks down and what to watch for in each part of it.
Longmont is a real city with a real industrial base, a historic downtown and a tech corridor that runs toward Boulder. A tenant looking for 2,000 square feet of retail and a tenant looking for 15,000 square feet of flex are shopping in completely different markets, even though both are "in Longmont."
The corridors, one by one
- Downtown Main Street. Historic storefronts, restaurants, breweries and upper-floor offices. Walkable and well-loved, with limited vacancy at any given time. Older buildings mean you should budget time and money for systems and code.
- Ken Pratt Boulevard and Hover Street. The auto-oriented retail backbone, with big-box anchors, pad sites and service retail. Visibility and traffic counts are the selling points; parking ratios and signage rights are what to negotiate.
- The Diagonal Highway. Office, R&D and tech campuses along the route to Boulder. Larger floor plates and, increasingly, sublease and second-generation office that can be a good value for a tenant who moves quickly.
- The east side and Vance Brand Airport. Flex, light industrial and contractor space. The east side has the better access to I-25, and the city-owned airport on the west edge of town has its own pocket of flex and hangar space. This is where you find roll-up doors, yard space and the power that manufacturing and trades need.
- North Main and Highway 66. Mixed older commercial and service uses. Often the most affordable option for a business that needs function over finish.
What decides what you pay
Base rent gets the attention, but in Longmont the bigger swings usually come from three places.
- Lease structure. Retail and flex are mostly triple-net, where you pay taxes, insurance and maintenance on top of rent. Some office is quoted full-service or modified gross. Comparing a NNN rate to a gross rate is comparing two different things; convert everything to an all-in monthly number.
- Condition of the space. A second-generation restaurant or a flex unit that already has the power and plumbing you need can save more than any rent concession. A cold shell can cost more to finish than you will pay in a year of rent.
- Specialized infrastructure. For flex and industrial users, three-phase power, clear height, dock versus grade-level doors and sprinklers are expensive or impossible to add later. Verify them on site, not from the flyer.
We do not publish asking rents in these posts. Longmont rates vary widely between a Main Street storefront, a Ken Pratt endcap and an east-side flex bay, and they move quarter to quarter. If you want current comps for your use and size, ask us and we will pull them.
A few Longmont-specific things to check
- Utilities and connectivity. Longmont runs its own municipal electric utility and NextLight fiber network. Confirm service and capacity at the specific building, especially for power-heavy or data-heavy users.
- Change of use. Converting office to medical, retail to restaurant, or warehouse to assembly use can trigger building code, parking and fire requirements. Get the city's read before you finalize the LOI.
- Sublease opportunities. Sublease space can come with existing furniture and improvements at a discount, but the term is limited to what is left on the original lease. Make sure that runway fits your plans.
How to run the search
- Decide your corridor first. Your customers, employees and suppliers should drive this, not where the first good sign happened to be.
- Start six months out. Longer for industrial users or any space that needs permits and a build-out.
- Tour real alternatives. In a market this size there is almost always a second option, and having one is what gives you leverage.
- Win the big points in the LOI. Rent, free rent, TI allowance, term, renewal options and expense caps.
- Review the full lease. Start with our lease checklist.
Where is commercial space for lease in Longmont?
Downtown along Main Street; Ken Pratt Boulevard and Hover Street for retail; the Diagonal Highway for office and tech; and the east side and the Vance Brand Airport area on the west edge of town for flex and industrial.
Is Longmont a good place for flex or industrial space?
It has one of the deeper flex and light industrial inventories in Boulder County, with access to I-25 and Boulder. It is often the answer when smaller neighboring towns do not have enough clear height, loading or power.
What should I check before leasing downtown?
Building systems, accessibility and change-of-use requirements. Confirm what the City of Longmont will require for your use, and who pays for upgrades, before you sign a letter of intent.
