Leases, Tenants, and Minimum Standards

The Fundamentals of Airport Lease Administration

Airport leases are different from standard commercial real estate leases. Your tenants operate on federally-obligated property, which means your lease terms must satisfy both your revenue needs and your grant assurance obligations. Every lease you sign is a compliance document as much as it is a business agreement.

Sound lease administration starts with understanding the core principles: set rates that reflect fair market value, include provisions that protect the airport's interests, track critical dates so nothing expires or lapses without your knowledge, and apply your policies consistently across all tenants.

Types of Airport Leases

Most small GA airports work with a few common lease structures:

• Hangar leases — For airport-owned T-hangars or box hangars rented to individual aircraft owners. These are typically month-to-month or annual agreements with relatively straightforward terms.
• Ground leases — For privately-built hangars or improvements on airport land. The tenant builds and owns the structure; the airport retains ownership of the land. Ground leases are typically longer (20–30 years) and more complex, with provisions for reversion of improvements at lease end.
• Commercial leases — For FBOs, flight schools, maintenance shops, and other commercial aeronautical operators. These involve minimum standards compliance, insurance requirements, and sometimes fuel flowage fees or percentage rent structures.
• Non-aeronautical leases — For compatible non-aviation uses on airport property, such as agricultural leases, cell tower sites, or warehouse space. These must be at fair market value and must not interfere with aeronautical operations.

Setting Fair Market Lease Rates

Grant Assurance 24 requires your airport to maintain a fee and rental structure that makes the airport as self-sustaining as possible. This means your lease rates need to reflect fair market value — not just cover costs, but generate revenue that supports the airport's long-term financial health.

Underpriced leases are a common problem at small airports, often the result of rates that were set years or decades ago and never adjusted. While below-market rates make tenants happy in the short term, they create two problems: they reduce the revenue available for airport maintenance and improvement, and they can constitute a compliance issue if the FAA determines you are not making the airport self-sustaining.

How to Determine Fair Market Value

There are several approaches to establishing that your rates are at market level:

• Comparable analysis. Survey lease rates at similar airports in your region. Your state aeronautics agency may maintain data on hangar and ground lease rates statewide, and organizations like the American Association of Airport Executives occasionally publish rate surveys.
• Independent appraisal. For ground leases and significant commercial leases, an independent appraisal by a certified real estate appraiser with airport experience provides the strongest documentation of fair market value.
• Cost recovery analysis. Calculate what you need to charge to cover the airport's operating costs, debt service (if any), and a reasonable contribution to capital reserves. This is a floor, not a ceiling — your rates should be at or above this level.

Whichever method you use, document it. If the FAA or a complainant challenges your rate structure, you need to be able to show how you arrived at your numbers.

Essential Lease Provisions

Every airport lease should include provisions that protect the airport's operational, financial, and compliance interests. The specific language will vary, but the following elements should be present in some form:

• Insurance requirements. Require tenants to maintain adequate liability insurance and name the airport sponsor as an additional insured. Specify minimum coverage amounts and require annual proof of coverage. Track insurance certificate expiration dates — a lapse in coverage creates unacceptable liability exposure for the airport.
• Maintenance obligations. Define what the tenant is responsible for maintaining (typically the interior and immediate exterior of their leased space) and what the airport maintains (common areas, airfield infrastructure). Be specific to avoid disputes.
• Compliance requirements. Require tenants to comply with all applicable federal, state, and local regulations, your airport's minimum standards (if applicable), and your rules and regulations.
• Default and termination. Define what constitutes a default, the notice period required, the opportunity to cure, and the process for termination if the default is not remedied. These provisions protect you when a tenant stops paying rent, violates lease terms, or creates safety hazards.
• Subordination to grant assurances. Include language stating that the lease is subordinate to the airport's federal obligations. This protects you from a situation where a lease term conflicts with a grant assurance.
• Rent escalation. As discussed above, include an automatic adjustment mechanism so rates keep pace with market conditions.
• Assignment and subletting. Address whether the tenant can assign the lease or sublet the space, and under what conditions. Unapproved subletting is a common issue at airports with hangar waiting lists — tenants sometimes informally sublet hangar space to other aircraft owners without the airport's knowledge.

Developing Minimum Standards

FAA Advisory Circular 150/5190-8 provides guidance on developing minimum standards for commercial aeronautical activities. While not federally mandated, the FAA strongly recommends that all federally-obligated airports establish minimum standards as a tool for fair, consistent, and legally defensible management of commercial tenants.

Minimum standards define the baseline qualifications, facilities, equipment, staffing, insurance, and hours of operation that any entity must meet to provide a given type of commercial aeronautical service on your airport. They apply to FBOs, flight schools, aircraft maintenance providers, charter operators, and any other commercial aeronautical activity.

Why Minimum Standards Matter

Minimum standards serve multiple purposes simultaneously:

• Fair competition. They ensure that every operator meets the same baseline, creating a level playing field for commercial activity.
• Quality control. They protect the quality of services available to airport users by requiring operators to meet defined thresholds for staffing, equipment, and facilities.
• Legal defense. They provide a documented, objective basis for decisions about who can and cannot operate on your airport. If you deny an application, minimum standards give you a defensible reason that is not based on personal preference or protectionism.
• Grant assurance compliance. Properly drafted minimum standards help you avoid exclusive rights violations (Grant Assurance 22) by establishing transparent criteria that any qualified applicant can meet.

Drafting Your Minimum Standards

The FAA cautions against two common mistakes in developing minimum standards. The first is adopting another airport's standards without modification — what works at a regional airport with 200 based aircraft may be entirely inappropriate for a local field with 30. Standards must be tailored to the specific conditions, size, and capacity of your airport.

The second is setting standards so high that they function as a barrier to entry. If your minimum standards require a level of investment, staffing, or facility space that only your current FBO can meet, you have effectively created an exclusive right through the back door. This is a direct path to a Part 16 complaint.

Good minimum standards are achievable but meaningful. They should raise the quality floor without creating artificial barriers. Start by identifying the categories of commercial activity that exist or are likely to be requested at your airport, then define reasonable requirements for each category.

Managing Tenant Relationships

Good lease administration is a necessary foundation, but it does not replace the need for effective tenant communication and relationship management. Most conflicts at small airports escalate not because the underlying issues are intractable, but because communication breaks down.

Proactive Communication

Keep tenants informed about airport activities, planned maintenance, construction projects, fee changes, and regulatory developments that affect them. This can be as simple as a periodic email update or a bulletin posted in a common area. Tenants who feel informed and included are far less likely to become adversarial.

Consistent Policy Application

Apply your policies the same way to every tenant. Granting exceptions to one tenant while enforcing rules strictly with another is a fast path to resentment, accusations of favoritism, and potential discrimination complaints. If a policy needs to be changed, change it for everyone.

Tenant Self-Service

Every time a tenant calls to ask about their lease term, payment history, or the status of a maintenance request, both of you are spending time on administrative tasks that could be eliminated through self-service access. Providing tenants with a portal where they can view their own information reduces your workload and improves their experience.

Hangar Use Compliance

FAA guidance is clear that airport hangars built with federal funds or on federally-obligated property are intended for aeronautical use. While incidental non-aeronautical storage (a workbench, tools, minor personal items) is generally acceptable, using a hangar primarily for non-aviation storage — boats, RVs, household goods — when there is a waiting list for aeronautical hangar space is a compliance issue.

Include hangar use provisions in your lease that clearly state the primary purpose of the hangar is aircraft storage and that the space must be used for aeronautical purposes. Conduct periodic inspections to verify compliance. When violations are found, work with the tenant to correct the situation through your lease's default and remediation procedures.
