Environmental Hazards Disclosure: Alaska Real Estate Exam Guide
Last updated: April 2026
For aspiring real estate professionals in the Last Frontier, mastering the intricacies of property disclosure is essential for both passing the state licensing exam and building a successful, ethical career. Among the most critical—and highly testable—areas of disclosure are environmental hazards. Because of Alaska’s unique geography, climate, and infrastructure, the environmental issues encountered here often differ significantly from those in the lower 48 states.
This comprehensive guide explores the regulatory frameworks, specific environmental hazards, and licensee responsibilities you must understand. Whether you are reviewing how to handle a leaking heating oil tank or studying the statutory requirements of the Alaska Residential Real Property Transfer Disclosure Statement, this material is a vital stepping stone toward conquering the Complete Alaska Exam Guide.
The Regulatory Framework: AS 34.70
In Alaska, residential property disclosures are governed by Alaska Statute (AS) 34.70. This law mandates that before a buyer makes a written offer, the seller of residential real property (up to four dwelling units) must provide a completed written disclosure statement detailing the condition of the property, including any known material defects and environmental hazards.
A "material defect" is defined as a condition that has a specific, adverse effect on the value of the property or poses an unreasonable risk to people. Environmental hazards almost always fall into this category. If a seller or their agent knows of an environmental issue and fails to disclose it, they can be held liable for actual damages—and in cases of willful concealment, up to treble (triple) damages.
Common Environmental Hazards in Alaska
To succeed on the exam, you must be able to identify specific environmental hazards that commonly affect Alaskan real estate and understand the disclosure requirements for each.
1. Permafrost and Soil Instability
Unlike most other states, Alaska has vast regions built on permafrost (permanently frozen ground). When permafrost thaws—due to climate changes, improper building insulation, or land clearing—the ground can shift dramatically. This leads to severe foundational settling, cracked walls, and structural failure. Sellers must disclose known permafrost issues or history of soil heaving. Real estate agents should be vigilant for signs of structural distress in areas known for permafrost, such as Fairbanks and the Interior.
2. Heating Oil Tanks and Spills
Because natural gas is not available in many rural and suburban parts of Alaska, residential heating oil tanks are ubiquitous. Both Underground Storage Tanks (USTs) and Aboveground Storage Tanks (ASTs) present significant environmental risks. A leaking oil tank can contaminate soil and groundwater, leading to astronomical cleanup costs.
The Alaska Department of Environmental Conservation (ADEC) strictly regulates oil spills. Any known past or present leaks, as well as the presence of abandoned or decommissioned USTs, must be explicitly disclosed to buyers. Licensees must understand that an undisclosed oil leak is one of the most common causes of post-sale litigation in Alaska.
3. Radon Gas
Radon is a naturally occurring, odorless, radioactive gas that seeps into homes from the ground. Prolonged exposure is the second leading cause of lung cancer. The Environmental Protection Agency (EPA) has identified several areas in Alaska, including parts of the Matanuska-Susitna Borough and Fairbanks North Star Borough, as having elevated radon potential. While Alaska law does not require sellers to test for radon prior to a sale, any known past test results must be disclosed.
4. Lead-Based Paint
This is a federal requirement that frequently appears on the national and state portions of the exam. Under the Residential Lead-Based Paint Hazard Reduction Act, any property built before 1978 requires a specific lead-based paint disclosure. Buyers must be given a 10-day window to conduct a risk assessment, and sellers must provide the EPA-approved information pamphlet.

Licensee Responsibilities and Fiduciary Duties
Real estate licensees in Alaska are bound by strict ethical and legal obligations. Under your agency relationship, you owe duties of reasonable care, honesty, and good faith to all parties in a transaction. When it comes to environmental hazards, this means you cannot participate in concealing a known defect.
If a seller informs you that their well water is contaminated but instructs you not to tell the buyer, you are facing a severe ethical dilemma. Your duty of confidentiality to the client does not override your duty to disclose known material defects to the buyer. Navigating these conflicts requires a deep understanding of the Alaska Fiduciary Duties of Agents.
"As-Is" Sales and Disclosures
A common misconception among sellers is that listing a property "As-Is" waives the requirement to disclose environmental hazards. This is entirely false. Under Alaska law, an "As-Is" clause simply means the seller refuses to make repairs; it does not exempt the seller from the requirements of AS 34.70. The seller must still disclose all known environmental hazards. Understanding how these clauses work is a vital part of Alaska Contract Essentials and Elements.
Tenant Rights and Environmental Hazards
Environmental hazards don't just affect buyers and sellers; they also impact property management. Landlords are legally required to maintain habitable premises. If a rental property has severe mold, an active heating oil leak, or dangerous radon levels, the landlord must address it. Property managers must be well-versed in the Alaska Landlord-Tenant Law Essentials to ensure environmental hazards do not violate the warranty of habitability.
Practical Scenario: The Buried Oil Tank
The Situation: You are the listing agent for a property in Juneau. During a walk-through, you notice a capped pipe in the yard. You ask the seller about it, and they admit there is an old underground 500-gallon heating oil tank buried there. They stopped using it ten years ago when they switched to electric heat. They mention they think it leaked a little bit before they stopped using it, but "it's buried, so it's not a problem anymore."
The Agent's Responsibility: As a licensee, you must inform the seller that this is a material environmental hazard that must be disclosed on the State of Alaska Residential Real Property Transfer Disclosure Statement. Furthermore, because a leak was suspected, ADEC regulations regarding contaminated sites may apply. If the seller refuses to disclose the tank and the suspected leak, you must withdraw from the listing. You cannot legally or ethically market a property while actively concealing a known environmental hazard.
Preparing for the Exam
When taking the Alaska real estate exam, pay close attention to questions that mix federal laws (like lead-based paint) with state-specific issues (like permafrost and ADEC oil spill reporting). Remember that the burden of disclosure primarily falls on the seller, but the licensee acts as the professional guide who ensures compliance. Always default to the rule of thumb: When in doubt, disclose.
Frequently Asked Questions (FAQs)
1. Is a seller required to test for radon or lead-based paint before selling a home in Alaska?
No. Neither Alaska state law nor federal law requires a seller to conduct new tests for environmental hazards prior to a sale. However, if tests have been conducted in the past and the seller has the results, those known results must be disclosed to the buyer.
2. How does Alaska law treat abandoned underground heating oil tanks (USTs)?
Abandoned USTs are considered a significant material fact and potential environmental hazard. Their presence must be disclosed on the property disclosure form. While residential heating oil tanks are exempt from some commercial EPA regulations, any known leaks must be reported to the Alaska Department of Environmental Conservation (ADEC), and cleanup may be required before a lender will finance the property.
3. Are "as-is" estate sales exempt from AS 34.70 environmental disclosures?
There are specific exemptions to AS 34.70, such as transfers pursuant to court orders, foreclosures, or transfers between spouses. However, simply stating a property is sold "as-is" does not grant an exemption. If the transaction does not fall under a specific statutory exemption, the disclosure form—including environmental hazards—must be completed to the best of the seller's knowledge.
4. What is the penalty for intentionally concealing an environmental hazard in an Alaska real estate transaction?
Under AS 34.70, a person who negligently violates the disclosure law is liable for actual damages. However, if a seller or agent willfully or intentionally conceals a known material defect (like a severe oil leak), they can be held liable for up to treble (triple) damages, plus attorney fees, and the agent may face disciplinary action from the Alaska Real Estate Commission.
5. Do environmental disclosure laws apply to commercial real estate in Alaska?
The specific mandatory disclosure form outlined in AS 34.70 applies only to residential real property of one to four units. Commercial real estate transactions rely on different mechanisms for environmental discovery, primarily the Phase I Environmental Site Assessment (ESA). However, commercial sellers and agents are still bound by general laws against fraud and the concealment of known latent defects.
