As the aviation industry accelerates into the latter half of the decade, a distinct and pressing challenge has emerged for aircraft owners, family offices, and corporate flight departments. We are witnessing a "hangar boom" driven not by speculative real estate development, but by a critical imbalance between the rapid delivery of next-generation aircraft and the stagnant supply of infrastructure capable of housing them.
By 2026, this dynamic is expected to reach a tipping point. With major OEMs like Gulfstream, Bombardier, and Dassault delivering record numbers of ultra-long-range jets, the scarcity of Class A hangar space has evolved from a regional headache into a nationwide strategic risk. For investors and operators alike, understanding the nuances of this shortage—ranging from door-height obsolescence to the rising cost of steel—is no longer optional; it is a fundamental requirement for protecting aviation assets.
The term "shortage" has been used in business aviation for years, but the 2026 landscape presents a unique structural crisis. Historically, hangar demand fluctuated with the economy. Today, however, we are seeing a decoupling of hangar demand from broader economic cycles. Even as economic indicators shift, the backlog of private aircraft orders remains at historic highs.
According to detailed reports from Aviation Week, waiting lists for hangar space at general aviation airports are growing longer, with no immediate relief in sight. The U.S. business jet fleet has expanded significantly, with thousands more aircraft forecast for delivery through the early 2030s. Crucially, retirement rates for older aircraft are low. We are not swapping old planes for new ones; we are adding net new inventory to a finite amount of airport real estate.
This "lag" has created a severe deficit that will define the market in 2026. Owners taking delivery of $75 million assets are finding themselves on 3-year waitlists for hangar space in key metropolitan hubs like Teterboro (TEB), Van Nuys (VNY), and Miami-Opa Locka (OPF). As FBOs struggle to add capacity fast enough, valuable aircraft are increasingly forced to park on the ramp, exposed to the elements.
The shortage is not just about square footage; it is about cubic volume and aperture. A significant percentage of the existing U.S. hangar stock was built in the 1970s and 1980s, designed for the Learjets, Hawkers, and early Gulfstreams of that era. These facilities are functionally obsolete for today's flagship aircraft.
The critical choke point is tail height. Modern ultra-long-range jets have fundamentally different vertical requirements:
For example, the Gulfstream G700 has a tail height of 25 feet, 5 inches (refer to official Gulfstream specifications), and the Bombardier Global 7500 sits at approximately 27 feet (see Bombardier specifications). Many legacy hangars feature 20-foot to 24-foot clear openings. This simple geometric fact renders nearly half of the available hangar inventory at major airports unusable for the top tier of the market.
This creates a bifurcated market: plenty of space for light jets, but a desperate scramble for "Class A" facilities capable of housing heavy metal. Owners are learning the hard way that you cannot simply "retrofit" a higher roof onto a pre-engineered metal building; in most cases, demolition and new construction are the only options.
One of the most critical, yet often overlooked, drivers of the 2026 hangar boom is the regulatory landscape surrounding fire suppression. The National Fire Protection Association (NFPA) 409 standard governs aircraft hangar fire protection.
For decades, the standard requirement for large (Group I) hangars was high-expansion foam systems. However, these systems have proven problematic due to accidental discharges that can damage aircraft and the environmental hazards associated with PFAS "forever chemicals" found in older foams.
Recent updates to the code have introduced alternatives, such as Ignitable Liquid Floor Drainage Assemblies and risk-based approaches that may allow for water-only sprinkler systems in certain configurations. However, implementing these modern, safer systems requires new construction or massive capital improvements to existing floors.
Organizations like the National Air Transportation Association (NATA) have been pivotal in advocating for these changes. As they note, the shift away from foam lowers long-term liability but often increases the initial complexity and cost of the floor slab and drainage infrastructure. AGP Aviation prioritizes these modern suppression technologies in our developments to ensure asset protection and future-proof regulatory compliance.
Why hasn't the market corrected this supply-demand imbalance? The answer lies in the soaring cost of development. Heading into 2026, developers face a "perfect storm" of economic pressures that set a high floor for rental rates.
According to the latest Turner Building Cost Index, construction costs have continued to rise steadily, driven by labor shortages and material prices. This means that any new supply coming online in 2026 will inevitably command premium lease rates to justify the construction investment.
Navigating the 2026 hangar boom requires a proactive strategy. For aircraft owners, waiting until delivery day to secure real estate is a recipe for operational failure.
We recommend engaging in infrastructure planning 12 to 24 months before aircraft delivery. This may involve securing pre-lease agreements at facilities under construction or working with consultants to identify off-market opportunities.
The current market offers a generational opportunity to modernize airport infrastructure. However, success requires deep industry expertise to navigate the "public-private" nature of airport ground leases. At AGP Aviation, we specialize in bridging the gap between municipal airport authorities and private capital, ensuring that development projects are both financially viable and operationally compliant.
The shortage is the result of a "lag" between rapid fleet growth and slow infrastructure development. While aircraft manufacturers have ramped up production of new large-cabin jets (like the G700 and Global 7500), hangar construction has been slowed by high costs, land scarcity, and complex regulatory entitlement processes. This has created a bottleneck where new planes are arriving faster than hangars can be built.
For the Gulfstream G700, the tail height is 25 feet, 5 inches. For the Global 7500, it is approximately 27 feet. To operate safely, a hangar door clear height of 28 feet is recommended. Most legacy hangars built before 2005 have 20-to-24-foot doors, making them incompatible with these ultra-long-range jets.
Recent updates to NFPA 409 allow for alternatives to traditional high-expansion foam fire suppression systems. This is significant because foam systems carry risks of accidental discharge and environmental contamination (PFAS). Modern hangars can now be designed with "Ignitable Liquid Floor Drainage" systems or water-only deluge systems if specific risk criteria are met, though these systems often require more expensive initial floor construction.
In most cases, no. The primary limitation is geometry—specifically door height. You cannot simply "raise the roof" of a steel span structure without rebuilding it. Additionally, bringing older facilities up to modern fire code (NFPA 409) is often cost-prohibitive compared to new construction.
We do both. Ascension Group Partners (AGP) is a vertically integrated aviation real estate firm. We provide turnkey development services for new facilities and also offer specialized consulting for airport sponsors and private investors looking to navigate the complex aviation real estate market.
