Boulder Commercial Real Estate Broker: Retail, Office, Flex and Industrial
The Boulder commercial real estate market is small, unique, supply-constrained, and split into very different submarkets, from downtown office on Pearl Street to lab and flex space in East Boulder and Gunbarrel. We represent tenants, buyers, landlords, sellers, and investors throughout Boulder and Boulder County in most of these sub markets.
Our team brings more than 25 years of combined commercial real estate experience and over $100 million in property sold and leased along the Front Range in the last four years. We work on office, retail, medical, industrial, flex, and investment property, and we know how each Boulder submarket prices space differently.
The Boulder commercial real estate market in 2026
Boulder is home to the University of Colorado, federal research labs, and a deep base of technology, aerospace, natural-products, and life-science companies. The city's 55-foot height limit and surrounding open space keep new supply tight, which is why Boulder rents have historically run well above the rest of the metro.
However, not all sectors of the commercial market in Boulder are booming right now. Office is where tenants have a lot of leverage right now. According to Dean Callan & Company's mid-2026 report, Boulder office vacancy is about 21%, with a median rate near $22 per square foot NNN. In 2016 it was 7.5%. Another 284,000 square feet is available for sublease. For tenants, that means room to negotiate free rent, tenant-improvement (TI) dollars, and early-year rent steps, especially in older buildings. Don’t let the median rate for office fool you…the NNNs can be almost as much as the rent. So $22/ft can turn into $40/ft when you add all the costs. That changes the landscape for companies. If the $22 NNN expense sounds high, it is, but that is an entirely different story that primarily involves exorbitant taxes and fees from the city and county of Boulder.
The city is trying to change downtown's direction. In early 2026, the City Council asked staff to explore a downtown development authority to fund economic development and infrastructure improvements around Pearl Street. However, at the same time, the council has proposed a vacant building/space tax on landlords. So it is a mixed bag for both owners and lessees right now.
Lab and flex space is a separate market (see below), and well-located small-bay flex rarely sits long.
There is still active buying activity though. In Boulder County and the surrounding markets (Longmont / Erie etc) sales were close to $200M in the 1st half of 2026. Most are owner users as investor deals are getting harder and harder to pencil and finance. Stating the obvious, investors are looking for deals which typically means higher cap rates for one. Many Boulder sellers think that their property should garner a higher price because of the prestige of the area. Today, in our opinion, it seems that cap rates need to be at least 7% for any investor deal to really make sense. Especially when 10 year bond yields are in excess of 5% as of this post.
Boulder's commercial submarkets
Downtown Boulder and Pearl Street
Downtown has about 1.7 million square feet of office space, plus the Pearl Street Mall and the West End and East End retail and restaurant blocks. Downtown office vacancy is about 24%, down from roughly 29% a year earlier, with average rates near $26 per square foot NNN. No new downtown office is planned, so today's vacant space is the supply. Parking is the biggest practical issue: most downtown buildings offer about one space per 1,000 square feet, so tenants with staff or clients who drive need to plan for it. Downtown works well for retail, restaurants, professional services, and companies that recruit on walkability.
Central Boulder, 28th Street and Boulder Junction
Central Boulder has about 2.1 million square feet of office and has been the city's tightest office submarket. It includes the 28th Street and 30th Street retail corridors, Twenty Ninth Street, and Boulder Junction around the Depot Square transit station. Expect a mix of newer mixed-use buildings, older office spaces, and high-traffic retail pads with easier parking than downtown.
East Boulder and Flatiron Park
East of Foothills Parkway, East Boulder holds roughly 2 million square feet of office plus most of the city's flex, R&D, and light industrial space. Flatiron Park is the center of it. In 2022, BioMed Realty bought 23 properties in Flatiron Park for more than $600 million, and in 2025 the City Council approved its 207,000-square-foot research campus at 1855 S. Flatiron Court.
The city's East Boulder Subcommunity Plan, adopted in 2022, calls for up to 5,000 new homes and more mixed use in parts of the area over the next 10 to 20 years. If you're buying or redeveloping in East Boulder, check how the plan applies to your site before you price it.
Gunbarrel and the Diagonal Highway
Gunbarrel, northeast of the city along the Diagonal Highway (CO-119), has larger floor plates, more parking, and lower rents than central Boulder. It is a strong fit for flex, R&D, office-flex, and owner-users who want a Boulder address without downtown costs. Office vacancy in Gunbarrel and Niwot runs around 20%, so tenants have room to negotiate. Neighborhood retail along Lookout Road serves the residential growth nearby.
North Boulder and South Boulder neighborhood retail
North Broadway and the Table Mesa and Baseline areas in South Boulder are mostly neighborhood-serving retail and small office: restaurants, services, fitness, and medical and dental practices that want to be close to where patients live. Space here is usually small and turns over quietly, often before it is publicly listed. Retail rents step down from roughly $34 per square foot NNN downtown to about $20 in North Boulder. The strongest demand is from wellness and fitness tenants, especially Pilates studios, along with food and outdoor-lifestyle concepts.
Lab, flex and R&D space in Boulder
Boulder is the center of the region's life-science and R&D market. According to CBRE, Boulder's lab direct vacancy was 18.7% in Q2 2026, but leasing over the prior four quarters was the highest in four years. Recent deals include VitriVax's 31,500-square-foot lease at 5500 Central Avenue and SomaLogic's 31,100-square-foot renewal. So there is some bright spots for owners after the last few years.
The development pipeline has nearly stopped. Novo Nordisk's 41,100-square-foot building at the Pearl East campus delivers in 2026, and the Element Research Center in Gunbarrel has finished the first phase of a 180,000-square-foot speculative conversion. With no new starts, tenants have choices today, but that may not last.
Flex space is a broader market than lab. Across Boulder and nearby towns, Dean Callan puts flex vacancy at about 17%, with average rates near $20 per square foot NNN and more than 700,000 square feet of tenant demand. Another 400,000-plus square feet is planned, including 1855 S. Flatiron Court and Redtail Ridge.
Quantum computing and related businesses are a growing source of the flex space demand. Oxford Ionics leased about 22,000 square feet at 1685 38th Street, and Mesa Quantum leased about 10,000 square feet on 55th Street. Giant Bicycles took 44,000 square feet at 3825 Walnut Street for its new headquarters. Although we're not exactly sure how Giant bicycles is quantum computer related, maybe their new ebikes are really something special - haha.
We have the experience to help lab, R&D, and flex users compare power, HVAC, clear height, loading, and buildout costs, and we help owners decide whether to market space as lab, flex, or office.
Medical and dental office space in Boulder
Boulder's healthcare market is anchored by Boulder Community Health's Foothills Hospital campus at Arapahoe Avenue and Foothills Parkway, with about 430 affiliated physicians. Medical office demand clusters around the
campus and Riverbend, with dental and specialty practices spread across Central Boulder, North Broadway, and Table Mesa. However, any office space can easily be converted to a space for primary care, for example. Typically, primary care offices would require some mill work, plumbing and some reconfiguration of the layout.
We help Boulder doctors, dentists, orthodontists, veterinarians, physical therapists, and specialty practices with:
Finding second-generation medical and dental space with plumbing, X-ray shielding, and ADA access already in place
Converting general office to clinical use, including zoning, parking, and buildout feasibility
Lease-versus-buy analysis for practice owners ready to own their building
Negotiating TI allowances, exclusive-use clauses, and assignment rights you will need when you sell the practice

Selling or exchanging Boulder investment property
Boulder has always drawn more buyers than it has buildings for sale, including institutional investors who rarely buy in smaller markets. If you own a Boulder office, retail, medical, or flex property, we'll show you what comparable buildings have actually traded for, what buyers are underwriting in today's vacancy, and whether a sale, refinance, or 1031 exchange makes the most sense. In the first half of 2026, properties took about 9 months to sell and closed about 5.8% below asking, so pricing and preparation matter. 9 months is quite a long time. If priced right, it shouldn’t take 9 months to sell a property. In today’s market, Sellers need to realistically understand that this is not 2021. If you want 2021 pricing, be prepared to offer 2021 terms. Seller financing can be a strategy for this.
We help sellers structure seller financing to widen the buyer pool and help 1031 buyers find Boulder replacement property inside the 1031 exchange window.
Boulder commercial real estate FAQs
How much does a Boulder commercial real estate broker cost? For tenants, usually nothing out of pocket; the landlord typically pays the leasing commission. Sellers and landlords pay a negotiated commission, generally a percentage of the sale price or lease value.
Is now a good time to lease office space in Boulder? For many tenants, yes. Boulder office vacancy was above 20% in mid-2026, and about 24% downtown, which gives tenants leverage on rent, free rent, and buildout dollars. Central Boulder is tighter, so leverage depends on the submarket.
What are typical lease structures in Boulder? Most Boulder office, retail, medical, and flex space leases on a triple-net (NNN) basis, where the tenant pays its share of property taxes, insurance, and common-area maintenance. Compare total occupancy cost, not just the base rent.
Is parking a problem for downtown Boulder office space? Most of the time, yes it is. Most downtown buildings offer about one parking space per 1,000 square feet. Central Boulder, East Boulder, and Gunbarrel usually have more parking at lower cost.
Where can I find lab or flex space in Boulder? Most of it is in East Boulder around Flatiron Park and in Gunbarrel along the Diagonal Highway. Boulder lab vacancy was close to 20% in Q2 2026, so tenants have options today, but very little new space is being built.
Can I convert general office space in Boulder to medical or dental use? Often, but it depends on zoning, parking, plumbing, ADA access, and building systems. We check feasibility before you sign so you don't inherit a costly surprise.
Do you help with 1031 exchanges in Boulder? Yes. We help sellers market relinquished property and help buyers identify Boulder replacement property within the 45-day identification and 180-day closing deadlines.
What areas around Boulder do you cover? All of Boulder, including Gunbarrel, plus Louisville, Lafayette, Superior, Broomfield, Longmont, Niwot, and the rest of the Front Range.
