Aerospace suppliers occupy a narrow band of the industrial real estate market where the criteria for site selection go far beyond power, ceiling height, and truck access. The convergence of airside operations, federal security mandates, and a specialized labor market means that a site decision made without a structured evaluation framework can constrain growth for decades.
Why Standard Industrial Site Criteria Fall Short for Aerospace
Most industrial site-selection frameworks were designed for distribution, light manufacturing, or food processing. They weight transportation access, labor cost, incentive packages, and proximity to customers. Those variables matter for aerospace suppliers too, but they sit beneath a layer of requirements that do not appear in a standard broker checklist.
Airside access — the ability to move aircraft, engines, large components, or tooling directly between a facility and an active taxiway or runway — is either available at a given address or it is not. No tenant improvement package can create it. Securing it after the fact typically means negotiating a complex easement or lease amendment with an airport authority, a process that can take years and may ultimately fail.
Federal security compliance adds another dimension that most industrial tenants never encounter. Aerospace facilities that handle export-controlled technology, classified programs, or sensitive government contracts must meet specific physical security standards. Those standards affect everything from perimeter fencing and lighting to badge access architecture and visitor controls. A building that cannot be brought into compliance without structural reconstruction should be treated as a disqualifying site, not a value-add opportunity.
The skilled trades question is equally structural. Aerospace manufacturing and MRO operations depend on workers who hold specific certifications — FAA Airframe and Powerplant licenses, NADCAP process qualifications, AS9100 quality system familiarity, and journeyman-level precision machining credentials. These credentials take years to earn and are not interchangeable with general industrial labor. A location with low unemployment but no aerospace-trained workforce is not a labor advantage; it is a long training liability.
Building the Evaluation Team Before the Search Begins
A site search that begins without the right internal stakeholders assembled will produce a site decision optimized for the wrong criteria. The evaluation team for an aerospace supplier should include the senior real estate or facilities lead, the director of operations, the security officer or facility security officer if the company holds government clearances, the head of human resources, and finance leadership who can model the full occupancy cost over a relevant lease or ownership horizon.
Each of these voices catches a different category of disqualifying risk. Operations will flag ceiling heights, column spacing, crane rail capacity, and apron access. The security officer knows whether the building's construction and location can support a sensitive compartmented information facility or a controlled access area, even if those facilities are not immediately needed. HR understands which labor markets have produced the skilled trades the company relies on and which have not.
Engaging outside counsel with aerospace regulatory experience early in the process is not a formality. Export control compliance under the International Traffic in Arms Regulations and the Export Administration Regulations shapes where certain materials, components, and technical data can physically be stored and reviewed. A site that is otherwise ideal may create compliance complications if it shares a building with foreign-owned tenants or sits within a foreign trade zone with conflicting obligations.
Commissioning a security consultant before the shortlist is finalized is equally important. Security consultants who specialize in defense and aerospace facilities can walk a candidate site and identify construction modifications that would be required to meet baseline standards. Getting that assessment before signing a letter of intent saves the cost of discovering those modifications during diligence.
Defining Runway Access Requirements with Precision
"Runway access" is not a single requirement — it is a cluster of related operational needs that vary significantly by the type of aerospace work being performed. An MRO operation that accepts wide-body commercial aircraft has fundamentally different access requirements than a supplier that only needs to move palletized components onto charter freighters. Defining the actual operational need before the search begins prevents the team from over-specifying in ways that eliminate viable options or under-specifying in ways that create operational constraints after occupancy.
The starting point is a clear statement of what must physically move between the facility and the airside environment. If aircraft must be towed, the team needs to know the largest aircraft type, its weight, and its wingspan. Those figures determine minimum apron dimensions, pavement load ratings, and taxiway clearance requirements. Airport authorities publish pavement classification numbers and aircraft classification numbers for their movement areas, and a simple comparison against the heaviest aircraft in the operating fleet will confirm whether a candidate airport can support the operation at all.
If the movement is limited to components, tooling, or finished assemblies rather than complete aircraft, the analysis shifts to door dimensions, ground-level loading, and the logistics corridor between the building and the airside gate. Some airports allow landside-to-airside access through a customs and border protection checkpoint, which introduces inspection times and scheduling constraints that affect production planning. Others offer sterile airside access for credentialed operators without a CBP inspection requirement, which is operationally simpler but may require a separate agreement with the airport authority.
Lease or ground lease terms at airport-adjacent properties are often structured by the airport authority itself, and those leases carry obligations that private landlords do not impose. Revenue-sharing clauses, signage restrictions, environmental reporting requirements, and reversion rights for improvements are common. The financial modeling for an airport property must account for all of these terms, not just the base rent per square foot and operating expense stops.
Evaluating Security Infrastructure and Compliance Readiness
For companies that hold or pursue security clearances, the physical plant is part of the classified program infrastructure. The Defense Counterintelligence and Security Agency publishes facility security requirements that govern how classified information is stored, discussed, and accessed. A building that cannot support those requirements — because its walls are insufficient, its HVAC penetrations are uncontrollable, or its proximity to public access points creates acoustic risks — will not be approved for use as a classified facility.
The evaluation process should include a preliminary review of the building's construction type against the applicable security standard for the highest classification level the company currently holds or intends to pursue. Concrete tilt-up construction with minimal exterior glazing is generally easier to bring into compliance than glass-curtain office construction. Older industrial buildings sometimes have wall assemblies, suspended ceilings, or utility penetrations that require extensive remediation.
Perimeter security is a separate evaluation track. The minimum standoff distance between the building and any uncontrolled vehicle access point is a function of the classified or export-controlled activity being conducted inside. Some sites simply cannot achieve the required standoff without purchasing adjacent land, which may not be available or may be prohibitively expensive. A scoring matrix that assigns a numeric weight to standoff distance achievability helps the team make a defensible comparison across candidate sites.
Physical access control systems — badge readers, mantraps, visitor management infrastructure — are typically tenant improvements in industrial leases, meaning the cost falls to the occupier. Budget modeling should include not just the installed cost of these systems but the ongoing maintenance and compliance audit cost. Access control technology that was certified for classified use in one program year may require upgrade or replacement in a subsequent review cycle.
Cybersecurity and communications infrastructure are increasingly treated as part of physical security during government facility reviews. A building's existing fiber connections, carrier diversity, and backup power architecture affect whether the tenant can meet the uptime and redundancy standards that certain programs require. Evaluating these infrastructure elements during site diligence, rather than after lease execution, prevents expensive remediation.
Scoring Skilled Trades Availability Across Candidate Markets
Labor availability for aerospace work cannot be assessed with headline unemployment numbers or general workforce counts. The relevant population is a small subset of the broader labor market: workers who already hold the specific certifications, have logged the required hours in precision manufacturing or MRO environments, and are either currently employed in aerospace or are within reasonable commuting distance of a candidate site.
The most reliable data source for aerospace labor depth is a combination of occupational employment statistics from the Bureau of Labor Statistics broken out by metropolitan statistical area, supplemented by analysis of active job postings in each candidate market over a trailing period. The BLS Occupational Employment and Wage Statistics program publishes location quotients for aerospace-specific occupational codes, which show how concentrated a given occupation is in a labor market relative to the national average. A market with a high location quotient for aircraft mechanics and service technicians is demonstrably more likely to contain the workforce a supplier needs than a market where aerospace employment is sparse.
Community college and technical school program pipelines are the next data layer. Markets where a local institution runs an accredited Aviation Maintenance Technician program, an aerospace manufacturing pathway, or an advanced machining curriculum have a self-replenishing talent supply that markets without those programs do not. Contacting the program directors at candidate-market institutions during the site search — not after the lease is signed — gives the team ground-level intelligence about graduation rates, employer relationships, and whether program capacity is growing or contracting.
Union relationships matter in many aerospace markets. In markets where the International Association of Machinists and Aerospace Workers or similar unions have significant penetration, the availability of journeyman labor through the union hall is a meaningful operational asset. However, work rules, jurisdictional boundaries, and prevailing wage obligations must be understood before committing to a site where union labor is the primary talent source. Treating these as details to be resolved after site selection is a common and costly mistake.
Workforce incentives offered by state and regional economic development agencies can offset training costs, but they should be modeled as a credit against the total occupancy and labor cost, not treated as a standalone reason to select a site. Incentive packages vary in structure, duration, clawback provisions, and the employment and wage commitments they require. Qualifying for an incentive that requires maintaining a specific headcount in a market where the talent pool is thin creates a compliance risk if growth stalls or the workforce proves difficult to recruit.
Structuring the Quantitative Scoring Model
A site selection decision for an aerospace supplier should be anchored in a scoring model that converts qualitative assessments into comparable numeric scores across candidate sites. The scoring model does not make the decision — it makes the trade-offs explicit so that the team's judgment is applied to the right questions rather than spent on incomplete comparisons.
The model should separate criteria into three categories: threshold requirements that are binary pass-or-fail, primary weighted criteria that differentiate among qualifying sites, and secondary criteria that inform the final ranking among closely scored options. Runway access of the required type is typically a threshold criterion. A site that cannot support the physical movement of the aircraft or components involved does not advance to weighted scoring regardless of its other merits.
Primary weighted criteria for an aerospace supplier typically include security compliance readiness scored on a scale that accounts for the cost and feasibility of required modifications, skilled trades availability scored using the BLS location quotient and pipeline analysis described above, lease or ownership economics expressed as a net present value comparison using a consistent discount rate and lease term, proximity to tier-one customer locations or shared logistics corridors, and utility infrastructure adequacy for manufacturing process requirements.
Secondary criteria might include state and local tax environment, incentive availability net of compliance cost, quality of life factors that affect executive and senior technical staff recruitment, and transportation infrastructure beyond the airside connection. These criteria are real but should not override a strong primary-criteria differential between sites.
The NPV comparison for lease economics should use effective rent — the true economic rent after abatements, tenant improvement allowances, operating expense reconciliations, and any free-rent periods — rather than face rate. A hypothetical example: a site with a face rate of eighteen dollars per square foot but a twenty-four-month free rent period and a forty-dollar per square foot tenant improvement allowance may have a lower NPV cost over a ten-year term than a site with a face rate of fifteen dollars per square foot and minimal concessions. Modeling both on the same term and discount rate before comparing them is the only defensible approach.
Diligence Workflows for Airside and Security Agreements
Once a preferred site emerges from scoring, the diligence phase must cover a set of agreements that are specific to aerospace and airport environments. These include the airport lease or ground lease with the airport authority, any airside access agreement or through-the-fence agreement that governs movement between the facility and the taxiway system, and the security agreement or memorandum of understanding with the relevant government security authority if classified work is involved.
Through-the-fence agreements — which grant a landside tenant physical access across the airport boundary to the airside movement area — are negotiated individually with each airport authority and are not standardized. The Federal Aviation Administration has published guidance on through-the-fence arrangements, and airport authorities have discretion to permit or deny them and to set the terms. Diligence should confirm that the airport authority is willing to enter a through-the-fence agreement, what the fee structure is, what operational restrictions apply, and whether the agreement can be assigned or transferred in the event of a business sale or restructuring.
The airport authority's master plan is a critical diligence document. If the authority's twenty-year capital plan includes runway extensions, new terminal development, or changes to the taxiway system adjacent to the candidate site, those improvements could affect access routes, introduce construction noise and disruption, or in extreme cases require relocation of the tenant facility. Reviewing the master plan and attending a public meeting of the airport authority's planning committee, if one is scheduled during the diligence period, costs little and can surface material risks.
Environmental diligence at airport-adjacent sites carries additional complexity. Aircraft fuel storage, de-icing fluid runoff, and historical industrial uses at airports have left legacy contamination at many sites. Phase I and Phase II environmental assessments should be conducted before lease or purchase execution, and the scope should explicitly include review of any airport authority environmental database or consent order that governs contamination on or adjacent to the candidate parcel.
Managing the Documentation Load Across Multiple Candidate Sites
A multi-site aerospace evaluation generates a substantial volume of material. Scoring matrices, lease abstracts, environmental reports, labor market analyses, security assessments, and airport authority correspondence all accumulate quickly, and keeping that material organized is an operational requirement rather than an administrative preference. Teams that manage this material in shared drives without a consistent naming convention or version control discipline routinely encounter the same problem: a critical document — a revised through-the-fence agreement term sheet or an updated environmental scope — is saved in the wrong folder or overwritten, and the team makes a decision based on a superseded version.
The discipline of centralized document management pays additional dividends at the end of the process. Lenders, program officers, or government security reviewers who need to validate the site decision can be given access to the relevant record without requiring the team to reconstruct the file from scratch.
Coordinating with Economic Development Agencies Without Losing Focus
State and regional economic development agencies actively pursue aerospace suppliers because of the high-wage jobs and supply-chain density that aerospace operations generate. Agencies in aerospace-concentrated states typically have dedicated aerospace sector teams, pre-qualified site inventories, and relationships with airport authorities that can accelerate the access agreement process.
Engaging these agencies early can provide genuine value — site inventory that is not publicly listed, introductions to airport authority leadership, preliminary incentive term sheets, and workforce pipeline data that would otherwise require independent research. The risk is that agency staff, who have an interest in landing the project, may present a site's challenges less directly than an independent adviser would. The scoring model should be completed using the team's own data, with agency-provided information treated as a supplementary input rather than the primary source.
Incentive negotiations with state agencies for aerospace projects often involve job creation commitments, average wage commitments, capital investment thresholds, and in some cases specific program or contract requirements that the agency uses to characterize the economic impact. Before signing an incentive agreement, the legal and finance teams should model the clawback exposure — the amount the company would owe if it failed to meet a commitment — against the probability that business conditions could prevent compliance. An incentive that creates a larger clawback liability than the value of the incentive itself is a net negative.
Finalizing the Recommendation and Securing Board or Executive Approval
The site recommendation for an aerospace supplier is typically a high-stakes capital commitment that requires board or executive approval. The recommendation document should present the scoring model results, the NPV comparison for lease economics, the security compliance assessment, the labor market analysis, and the key terms of the airport access and lease agreements in a single narrative that a non-specialist decision-maker can evaluate.
The recommendation should also present the risks that remain unresolved at the time of the decision — typically the through-the-fence agreement final terms, the incentive agreement execution, and the outcome of any environmental remediation negotiation. Decision-makers who are surprised by these risks after approval are more likely to revisit or reverse the decision. Presenting known uncertainties honestly, with a range of outcomes and a plan for each, builds confidence rather than undermining it.
This reduces the back-and-forth that typically extends the approval timeline and keeps the recommendation grounded in the underlying analysis rather than a summary of it.
The methodology described throughout this guide — from assembling the right evaluation team to building a quantitative scoring model, completing airside and security diligence, and structuring the recommendation — reflects the question that every aerospace real estate decision ultimately comes back to. How aerospace suppliers should evaluate runway access, security and skilled trades is not a question with a generic answer; it is a structured process that produces a defensible, documented decision that can be explained to a program officer, a lender, or a board.
