AirGarage Raises $23M Series B |
Your parking assets can add significant value to your property. This value is added in two primary ways:
Because commercial property valuation is based on NOI, even small improvements to parking revenue can lead to meaningful increases in overall property value. Our Co-Founder and CEO, Jonathon Barkl, puts it simply:
"You create value in real estate by either maintaining the cap rate and increasing your NOI, or you maintain your NOI and you decrease the cap rate - ideally you do both."
In this article, we walk through the main ways parking affects valuation, starting with the NOI and cap rate formula that drives commercial property worth. We’ll look at how parking influences tenant retention, and then explore how better parking operations can raise NOI.
Finally, we’ll show how these elements work together in a full valuation example with key takeaways for property owners.
The value of a commercial property is determined with a fairly straightforward formula:
Property Value = Net Operating Income (NOI) ÷ Cap Rate
Note: since the cap rate is the denominator in this equation, lower cap rates assign a higher multiple to each dollar of NOI.
For example, if your property generates $500,000 in NOI and trades at a 7% cap rate, it’s worth about $7.1 million. But if you increase that NOI to $550,000, it’s now worth $7.9 million. At this cap rate, a $50,000 boost in NOI adds $714,000 in property value.
That multiplier effect is why parking revenue matters so much.
Cap rates generally range between 4% and 10% depending on property type and location, but property valuation is not always perfectly linear. Market conditions, risk perception, and investor sentiment all influence cap rates.
Parking is sometimes an afterthought or a “box check” during lease negotiations, even though it directly influences tenant retention. The quality, ease-of-use, and accessibility of your parking setup can affect whether tenants renew or relocate (and whether they refer other tenants).
Replacing a commercial tenant is costly. Vacancy often leads to missed rent, higher tenant improvement allowances, and broker commissions that run 4–8% of the lease value. Additional marketing and legal expenses can raise that total further.
The overall cost can be up to 4-6 months of base rent. For a commercial tenant paying $150,000 annually, turnover may cost $50,000–$75,000. When parking frustrations trigger even one tenant departure every few years, NOI erodes quickly.
Research shows just how important parking is for prospective tenants:
When they’re considering a new lease, tenants are often curious about reserved versus general spaces, guest parking availability, violation enforcement, covered versus surface parking, and EV charging access. If your property can’t compete on meeting these expectations, you risk losing tenants or conceding on rent during renewals.
Tenant satisfaction research highlights the parking features tenants value most.
Improved tenant satisfaction reduces turnover and vacancy, so a property that minimizes vacancy directly increases NOI.
Consider a 200,000 SF building at $30 per square foot with 400 parking spaces. At 12% vacancy, effective gross income is $2.64 million. Reducing vacancy to 6% raises income to $2.82 million, an improvement of $180,000 per year. Using a 7% cap rate, that change alone creates roughly $2.57 million in additional property value.
Once tenant retention is optimized, direct revenue improvements are the next opportunity to drive NOI.
Many properties still give parking away by combining it with rent or using static pricing that fails to match demand. Parking by unauthorized drivers also limits space availability for paying tenants.
Plus, traditional parking operations often rely on expensive equipment and high overhead from on-site attendants, parking gates, or paper permits, which limit flexibility and prevent real-time tracking and insights.
Let’s go back to our example of the 200,000 SF office property with 400 parking spaces. If each space earns $50 per month, annual parking revenue is $240,000.
Better parking management could raise that rate to $75 per month, producing $360,000 per year. The increase of $120,000 in NOI translates to roughly $1.7 million in property value at a 7% cap rate.
How?
Modern parking technology (with dynamic pricing, consistent enforcement, efficient operations, mobile payments, etc.) simplifies management and reduces labor costs. Automation also strengthens enforcement and allows dynamic pricing based on occupancy and demand. Open spaces can be marketed through platforms like SpotHero or integrated systems that let users reserve and pay digitally.
“The key, of course, is that you need to know a way to increase your net operating income — and that might be dynamic pricing, better enforcement, or just a better deal structure.” - Jonathan, AirGarage Co-Founder & CEO
Here are just a few examples from AirGarage-managed properties:
If we use our 400-space parking facility again, the cumulative change is significant when tenant satisfaction and parking revenue optimizations combine.
Current state:
After optimization:
Result: $5.5 million increase in property value (13% appreciation).
The NOI rose through $120,000 in higher parking income, $240,000 more rental income, and $25,000 in cost savings - all achieved without major physical improvements or rent increases.
Getting the most from your parking comes down to understanding your property type and how better management will actually result in revenue growth.
Office buildings, for instance, tend to serve the same drivers Monday through Friday. Switch to digital permits and automated enforcement, and you'll cut way down on the administrative hassle.
But retail centers are almost completely different. You'll see packed parking lots on Saturday afternoons and during the holidays, then much lower demand on a Tuesday morning. This is where dynamic pricing makes a lot of sense. Let people pay digitally, adjust prices when it's busy, and those empty morning spots can actually start making you money.
Mixed-use properties are probably the trickiest. You've got residents who need their spots at night, office workers during the day, and shoppers coming and going whenever. The right technology can help you shuffle spaces around as needed and keep all three groups from wanting to strangle each other.
The bottom line? Look at how people actually use your property, then build your parking around those needs and behavior.
Many traditional and “modern” parking operators use flat-lease or cost-plus contracts that don’t promote efficiency or fiduciary responsibility. Revenue-share agreements keep incentives aligned so both parties share upside when revenue grows. We cover these issues in more detail in our full article on parking management agreements.
Properties offering free or bundled parking, static pricing, or staffed gates usually have hidden opportunities to improve parking revenue. Even though they’re common, these approaches suppress parking NOI and, by extension, property valuation.
Parking management systems like AirGarage’s can be installed quickly without upfront costs. This fast implementation shortens the time to measurable results. You can reference our handbook for more details on getting started and the steps to launch a modern, integrated parking management approach.
Parking plays a measurable role in driving property value through NOI growth and improved retention. Increasing revenue while lowering vacancy raises NOI, and applying your cap rate quantifies that boost as real market value.
Our team can help you understand how to upgrade your parking management approach, including projections and analysis on the impact to your property’s value.
