USE OF UNMANNED AIRCRAFT SYSTEMS IN INSURANCE
PRACTICES (AERIAL IMAGERY)
March 21, 2025
The purpose of this Bulletin is to provide guidance on the use of aerial imagery captured by
Unmanned Aircraft Systems (UAS) in insurance underwriting, claims handling, and other insurancerelated activities, while ensuring compliance with Delaware law and fair consumer practices.
Background
The FAA Modernization and Reform Act of 2012 (Pub. L. 112-95) (the Act) was enacted to
address the growing need for modernization and efficiency in the U.S. aviation system. The Act aimed
to improve air traffic control infrastructure, enhance aviation safety, and safely integrate UAS into the
national airspace. Section 332(b) directed the FAA to develop a regulatory framework for civil UAS
operations, resulting in the August 29, 2016, addition of Part 107 to Title 14 of the Code of Federal
Regulations. Several additional FAA UAS rules have also been promulgated.0Fi
In Delaware, commercial UAS operations are authorized under 14 C.F.R. Part 107 and governed
by 11 Del. C. § 1334.
Encouraging Innovation While Maintaining Consumer Protections
The Department recognizes the role of UAS in the insurance industry. UAS have proven to
enhance efficiency in claim processing, loss assessments, and underwriting by providing high-resolution
aerial imagery and reducing costs associated with traditional inspections. However, insurers must
balance these innovations with a commitment to fair consumer treatment, regulatory compliance, and
ethical standards.
Although aerial imagery is a useful tool for assessing property conditions, it has inherent
limitations, such as image distortion, weather interference, and the inability to capture fine details,
which may impact its accuracy and readability. While the Department does not intend to impose broad
restrictions on the use of UAS, it emphasizes the following to safeguard consumers, prevent unfair
business practices, and ensure underwriting decisions are properly supported:
Chapter 41 – Property Insurance Contracts
The use of aerial imagery for underwriting or claims purposes must align with Chapter 41, which
among other things, governs the denial and nonrenewal of policies. Policyholders must be given proper
notice and explanation when UAS imagery contributes to policy denial or nonrenewal.
• Policy Denial Notification
o A written explanation of the specific reasons for the declination must be provided to the
applicant pursuant to 18 Del. C. § 4122(a).
• Cancellation and Nonrenewal
Note: The Department encourages insurers to provide as much advance notice as possible
regarding nonrenewal.
o 18 Del. C. § 4122(b) requires that cancellation notices must be delivered or mailed at
least 30 days prior to the effective date of the cancellation, or 10 days prior to the
effective date of cancellation if cancellation is due to nonpayment of premium, and must
include a written explanation of the specific reason for the cancellation.
o For policies in effect for more than 60 days or after the effective date of a renewed
policy, the permissible reasons for cancelling a policy is limited to those circumstances
identified in 18 Del. C. § 4123.
o If an insurer intends to nonrenew a policy, 18 Del. C. § 4122(c) requires the insurer to
provide at least 30 days’ notice of the intention not to renew, which notice must include a
written explanation of the insurer’s specific reason(s) for nonrenewal.
The Department is aware that roof discoloration has been cited by insurers as a reason for
nonrenewal or cancellation. The Department maintains that cosmetic issues, such as discoloration and
streaking, do not constitute valid grounds for cancellation. Insurers must provide clear evidence of
significant degradation or damage that increases the risk of loss to support a cancellation decision. An
insurer must establish not only that a risk has increased but also that the increase is substantial.
It is essential for insurers to provide policyholders with a clear explanation of the specific
reasons for policy cancellation or nonrenewal. Nonspecific reasons, such as “claims experience,”
“underwriting judgment,” or “increase in hazard,” are unacceptable as they do not provide sufficient
notice for the insured to address the underlying issue. Providing detailed reasons enables the insured to
address the issue or secure alternative coverage if nonrenewal results from uncompleted repairs.
Chapter 23 – Unfair Practices in the Insurance Business
Insurers using UAS imagery must ensure compliance with 18 Del. C. § 2303. Additionally, the
Department expects insurers to:
• Ensure that statements regarding the accuracy or completeness of UAS imagery in policy
decisions are not deceptive or misleading.
• Safeguard that decisions based on UAS imagery are consistent, objective, and do not lead to
discriminatory underwriting practices.
• Maintain transparency by providing customers access to UAS captured imagery used in policy
determinations.
The Department recommends that if a customer disputes a finding based on aerial imagery, the
insurer should conduct a physical inspection to verify the accuracy of its assessment and ensure that
underwriting decisions are properly supported.
All property and casualty insurers operating in Delaware must ensure that their underwriting and

renewal practices align with this guidance. Failure to comply may result in regulatory review and
potential enforcement action as outlined in 18 Del. C. § 329.
The Department will continue monitoring UAS technology developments and encourages insurers to
adopt best practices, stay informed on regulatory updates, and ensure compliance with Delaware’s
consumer protection standards.
