🏠 Mandated Disclosures: What Every Real Estate Salesperson Needs to Know for the PSI Exam

A study guide for real estate license candidates, built around the PSI Exam Outline

If you’re getting ready to take the PSI Real Estate Salesperson License Exam, there’s a topic that always shows up: Mandated Disclosures. This section covers Mandated (Property) Disclosures: specifically, what sellers and agents must legally tell buyers about a property’s condition and environmental hazards. On the PSI national exam, Property Disclosures make up approximately 6–7% of your total score, which means you could see anywhere from 4 to 7 questions on this topic alone. That’s not a section you want to skip.

The favorable news? Once you understand the logic behind disclosure laws, you’ll see that protecting the buyer, being honest, and not hiding problems make a lot of sense. Let’s walk through each subtopic in the PSI outline and make sure you’re exam-ready.

📋 Part 1: Property Condition & Defect Disclosure

What Does “Disclose” Actually Mean?

At its most basic level, a disclosure is simply telling the truth about what you know. In real estate, sellers and their agents are required by law to disclose any known problems with a property that could affect its value, safety, or desirability.

Most states require sellers to complete a Property Condition Disclosure Statement (PCDS) — a standardized written form that covers everything from the roof and foundation to plumbing, electrical systems, and environmental hazards. Both the seller and the buyer must sign and date the completed form to confirm receipt.

Here’s the key part for your exam: you only have to disclose what you actually know. Sellers are generally not required to hire inspectors or dig through public records to discover problems before disclosing them. However, if you know about a problem and hide it, that’s fraud — and it can lead to lawsuits, contract rescission, and license suspension.

💡 PSI Exam Tip: If a question asks whether a seller must investigate unknown defects before completing a disclosure, the answer is almost always NO — they must only disclose known defects. But if they actively conceal a known problem, that’s a willful violation.

Material Facts vs. Latent Defects

These are two terms the PSI exam loves to test. Here’s how to keep them straight:

• Material fact: Any information that a reasonable buyer would consider important in deciding to buy the property or in setting the price. This is a broad category that includes physical defects, legal issues (like zoning violations), and environmental hazards.
• Latent defect: A hidden problem that you can’t easily see during a normal walkthrough. Think of a cracked foundation hidden behind finished drywall or a leaky roof that only causes problems during heavy rain.
• Patent defect: A defect that is visible and obvious during a normal inspection. Patent defects generally do not need to be disclosed because a buyer can see them for themselves.

Both sellers and real estate brokers have an independent legal duty to disclose material facts. Even if the seller doesn’t tell the agent about a defect, the agent can still be held liable if the agent reasonably should have known about it.

Property Disclosure Forms & “As Is” Sales

You’ll almost certainly see a question about “as is” sales on the PSI exam. Here’s the most important thing to understand:

“As is” does NOT mean “no disclosures.”

When a seller lists a property “as is,” they are saying they won’t make repairs after an inspection. But they are still legally required to disclose known latent defects to the buyer. Florida courts made this very clear in Rayner v. Wise Realty Co., where the court ruled that “as is” language cannot be used to shield a seller from disclosing known hidden defects.

Exam exceptions to know: Most disclosure laws do NOT apply to the following:

• Foreclosure sales and sales by court order
• Estate sales handled by a fiduciary (executor/trustee)
• Transfers between spouses
• New construction sold by the builder for the first time

💡 PSI Exam Tip: Watch for tricky wording. A question might state that a property is sold “as is” and then ask whether the seller must still disclose a known problem. The answer is YES — “as is” only eliminates the seller’s obligation to fix things, not to disclose them.

☣️ Part 2: Environmental Issues & Hazards

This part of the PSI outline requires disclosure of a range of environmental conditions during a real estate transaction. Some of these are regulated by federal law (like lead-based paint), others by state law, and some by both. Let’s go through them:

The Big 5 Environmental Hazards

Lead-Based Paint: The Federal Gold Standard for Disclosure

Because lead paint is regulated by federal law, it appears on virtually every real estate licensing exam in the country. Here’s what you absolutely need to know:

• Applies to any home built before 1978 (that’s the year the federal government banned lead paint in residential properties)
• The law is called the Residential Lead-Based Paint Hazard Reduction Act of 1992, or Title X
• Sellers, landlords, and their agents must:
  • Disclose any known lead-based paint and hazards
  • Provide buyers with the EPA pamphlet, “Protect Your Family from Lead in Your Home.”
  • Include a Lead Warning Statement in the contract
  • Give buyers a 10-day window to conduct a lead inspection (buyers can waive this in writing)
  • Please keep signed disclosure records for at least 7 years.

💡 PSI Exam Tip: The two numbers to memorize are 1978 (the cutoff year for lead-paint disclosure) and 10 days (the buyer’s inspection window). These are classic PSI question triggers.

Underground Storage Tanks, Groundwater, Brownfields & Wetlands

These topics often appear together on the exam and relate to a common theme: past industrial or commercial use can contaminate a property.

Underground Storage Tanks (USTs) store petroleum or hazardous chemicals, with at least 10% of the tank volume below the ground surface. The EPA recognizes leaking USTs as the leading source of groundwater contamination across the country. Property owners must disclose known USTs and properly close or remove tanks that are no longer in use.

Brownfields are abandoned or underused commercial or industrial sites that are known or suspected to be contaminated. Examples include old gas stations, dry cleaners, and manufacturing plants. The EPA’s Brownfields Program provides grants and liability protections to encourage redevelopment of these sites.

Wetlands are protected areas where land meets water, such as marshes, swamps, and bogs. Under the Clean Water Act (Section 404), filling, draining, or developing wetlands generally requires a federal permit from the Army Corps of Engineers. Unauthorized alteration of wetlands can trigger serious federal penalties.

💡 PSI Exam Tip: If a question mentions a former gas station, old dry cleaner, or industrial property being converted to residential use, think “brownfield” and “Phase I/II Environmental Assessment.”

Phase I and Phase II Environmental Site Assessments

These two assessments are the standard tools for environmental due diligence in real estate, especially for commercial transactions and any property with a history of industrial use.

An Environmental Impact Statement (EIS) is a broader federal document required under the National Environmental Policy Act (NEPA). It is required for major federal construction projects (highways, dams, military installations) that could significantly affect the surrounding environment. This document is different from a Phase I/II, which is property-specific due diligence.

💡 PSI Exam Tip: The PSI exam may ask what triggers a Phase II. The answer is a Phase I that identifies Recognized Environmental Conditions (RECs). Phase I doesn’t test the soil; it only reviews records and conducts a visual inspection.

⚖️ Part 3: Federal & State Environmental Laws

CERCLA — The Superfund Law

CERCLA stands for the Comprehensive Environmental Response, Compensation, and Liability Act. It was passed in 1980 after the country recognized the seriousness of contaminated site cleanup. CERCLA is sometimes called the “Superfund” law because it created a trust fund, originally built from taxes on the petroleum and chemical industries, to pay for cleanups when no other source of funds is available.

Here’s what makes CERCLA so powerful and so scary for property owners: it imposes three types of liability that are unusually harsh:

1. Strict Liability: You can be held responsible even if you personally did nothing wrong. If you own contaminated land, you may owe cleanup costs, period.
2. Joint and Several Liability: If multiple parties contributed to the contamination, any single party can be required to pay for the entire cleanup, not just their share.
3. Retroactive Liability: The law applies even to contamination that happened before CERCLA was passed in 1980.

Who can be liable under CERCLA? The EPA refers to these as Potentially Responsible Parties (PRPs):

• Current property owners and operators
• Former owners and operators at the time hazardous waste was disposed of
• Parties who arranged for the disposal of hazardous substances
• Transporters who selected the contaminated site

The Innocent Landowner Defense is a way to escape CERCLA liability. To qualify, a buyer must prove they conducted All Appropriate Inquiries (AAI): essentially, a proper Phase I ESA, before purchasing the property, and genuinely had no knowledge of the contamination. This is one major reason why Phase I assessments are so important in commercial real estate transactions.

💡 PSI Exam Tip: Memorize the three characteristics of CERCLA liability: strict, joint and several, and retroactive. These are key points for the PSI test. Also know that completing a Phase I ESA is the key step in claiming the Innocent Landowner Defense.

Clean Water Act & Clean Air Act

The Clean Water Act (CWA) of 1972

The Clean Water Act’s goal is to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.” In real estate, this is especially important because:

• The NPDES (National Pollutant Discharge Elimination System) permit program, which regulates discharges of pollutants into U.S. waterways
• Section 404, which gives the EPA and the Army Corps of Engineers authority to regulate filling and developing wetlands
• Properties near regulated water bodies or wetlands can face significant development restrictions that affect their value and usability

The Clean Air Act (CAA) of 1970 (originally 1963)

The Clean Air Act regulates both stationary sources (factories, power plants) and mobile sources (vehicles) of air pollution. Key points for the exam:

• The EPA sets National Ambient Air Quality Standards (NAAQS) for six “criteria pollutants”: carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide.
• Each state must develop a State Implementation Plan (SIP) to explain how it will meet those federal standards
• Properties near industrial facilities, highways, or in “non-attainment areas” (where air quality doesn’t meet federal standards) may require additional environmental review before development

💡 PSI Exam Tip: The Clean Water Act protects water; the Clean Air Act protects air. The CWA is most relevant for wetlands questions; the CAA is most relevant for industrial or commercial development near population centers. Both laws grant federal agencies authority to regulate activities that affect property use and development.

Final Exam Reminders 💪

Before you walk into that testing center, burn these five facts into your memory:

1. Sellers disclose what they KNOW: not what they haven’t discovered
2. “As is” means no repairs, NOT no disclosures: that trap is on almost every exam
3. Lead paint cut-off = 1978; buyer inspection window = 10 days
4. CERCLA = strict, joint/several, and retroactive liability: three words, tons of points
5. Phase I protects you under CERCLA: it’s the key to the Innocent Landowner Defense

Disclosure law exists for one reason: to protect buyers from being misled about what they’re purchasing. When you understand that core purpose, the rules stop feeling like memorization and start feeling like common sense. Good luck on your PSI exam — you’ve got this! 🎓
