What Things Should You Disclose When Selling A Home?

Selling a home in Silicon Valley can be an exciting yet challenging process. As a seller, you want to present your property in the best possible light to attract potential buyers. At the same time, you have a legal and ethical responsibility to disclose certain information about the property. Failure to disclose relevant details can lead to legal issues and potential lawsuits down the line. In this article, we will explore the key things you should disclose when selling a home in Silicon Valley, ensuring transparency and protecting yourself as a seller.

1. Stigmatized Property: Disclosing Unfortunate Events

One aspect of selling a home in Silicon Valley is dealing with stigmatized properties. These are properties where unfortunate events or issues have occurred, such as suicides, murders, criminal activities, or other misfortunes. While the laws regarding disclosing these events vary from state to state, it is essential to consult with your real estate agent and err on the side of transparency.

In California, for example, sellers and real estate agents are required to disclose any deaths that occurred on the property within the last three years. However, in Florida, such disclosure is not mandatory. It is crucial to be aware of the specific regulations in your area and work closely with your agent to determine what needs to be disclosed.

Everyone wants to know…

Murder and/or Deaths on the Property

In some cases, sellers may need to disclose any murders or deaths that have occurred on the property. The requirement for disclosure depends on the location of the property and the time frame in which the death took place. Understanding the laws in your area will help you navigate this sensitive topic.

Hauntings or Paranormal Events

Another aspect of stigmatized properties is the presence of hauntings or paranormal activities. While disclosure laws regarding reported hauntings vary, it is generally considered good practice to be upfront and honest with potential buyers. Some buyers may not believe in ghosts, while others may be uncomfortable with the idea of living in a haunted home. By disclosing any known paranormal events, you allow buyers to make an informed decision.

2. Pest Infestations: No Room for Creepy Crawlies

Pest infestations can be a significant concern for homeowners in Silicon Valley. Termites, snakes, mice, raccoons, bedbugs, and other pests can wreak havoc on a property. In most states, sellers are required to disclose any pest infestations, regardless of the severity. Even if you have had the property treated for pests before listing it, it is essential to inform potential buyers of any past or current infestations.

Termite Damage

Termites can cause extensive damage to a property, compromising its structural integrity. If your home has been affected by termites in the past, it is crucial to disclose this information to buyers. Providing details about the treatment and any repairs made will give buyers confidence in the property’s condition.

3. Lead-Based Paint: Protecting Buyers’ Health

The use of lead-based paint is a significant concern, especially in older homes. Lead-based paint can pose health risks, particularly to children and pregnant women. Federal law requires sellers to disclose any known information about lead-based paint in homes built before 1978.

Under the Residential Lead-Based Paint Hazard Reduction Act of 1992, sellers must provide buyers with a pamphlet prepared by the US Environmental Protection Agency (EPA) titled “Protect Your Family from Lead in Your Home.” This guide offers tips on how to keep families safe from lead-based paint. Buyers also have the right to test the property for lead within ten days.

It is crucial to disclose any information about lead-based paint, even if you believe it has been removed from the property. Failure to comply with lead-based paint disclosure requirements can result in legal consequences.

4. Other Known Toxic Materials: Ensuring Safety

In addition to lead-based paint, there are other hazardous materials that sellers should disclose to potential buyers. Two common examples are asbestos and radon.


Asbestos is a toxic material that can cause severe health problems when its fibers are inhaled. It is commonly found in older homes, particularly in thermal insulation and vinyl floor tiles. Depending on your state’s regulations, you may be required to disclose the presence of asbestos in your property. However, there may be exceptions if the asbestos is hidden and not easily accessible.


Radon is a toxic gas that can seep into homes from the ground, causing lung cancer with prolonged exposure. It is also known to contaminate well water. Some buyers request radon testing as part of the overall home inspection process, although it is not common in most parts of the Bay Area. If high radon levels are detected, it is important to disclose this information to potential buyers.

5. Water Damage and Drainage Issues: Preventing Future Problems

Water damage and drainage issues can lead to significant problems for homeowners. If your property has experienced water damage or has drainage issues, it is crucial to disclose this to potential buyers. Water infiltration can lead to mold growth, which can have adverse health effects. By being transparent about these issues, you protect yourself as a seller and allow buyers to make informed decisions.

6. Mold: Dealing with a Common Problem

Mold is a common issue that sellers need to address when selling a home. While every home has some amount of mold, certain types, such as toxic black mold (Stachybotrys), can cause health problems. Many states require sellers to disclose any known mold issues. Even if you have had mold remediation done in the past, it is essential to disclose this information to potential buyers.

7. Neighborly Disputes or Boundary Issues: Maintaining Good Relations

Neighborly disputes can escalate and become significant issues when a property changes hands. If you have had any disputes with neighbors regarding property lines or other matters, it is important to disclose these issues to potential buyers. While not mandatory, informing buyers about neighbor-related issues can prevent future conflicts and allow buyers to make informed decisions.

8. Sex Offenders: Knowing Your Area’s Rules

The laws regarding disclosing the presence of sex offenders near a property vary by state. It is crucial to check with your local real estate agent or visit the police department to understand the rules in your area. Ensuring that potential buyers have access to this information allows them to make informed decisions about the neighborhood.

9. Noise Pollution and Environmental Hazards: Considering Surroundings

Disclosing any issues that could affect the marketability of the property is essential. This includes environmental hazards near the home and other off-site conditions. If there are waste plants, contaminants, or other potential hazards nearby, it is important to inform buyers. Additionally, if the property is located in an earthquake zone, flood-prone area, or wildfire-prone region like California, disclosure is required. Proximity to airports or railways that may cause noise disturbances should also be disclosed.

10. Roof and Foundation Issues: Ensuring Structural Integrity

Roof and foundation issues can have a significant impact on a property’s value and safety. It is crucial to disclose any issues with the roof, such as leaks or damage, to potential buyers. Similarly, if the property has experienced foundational problems like cracks or sinking, this information should be disclosed. Buyers will likely uncover these issues during inspections, so transparency from the beginning is important.


When selling a home in Silicon Valley, transparency and disclosure are key. By understanding the legal requirements and ethical obligations, you can protect yourself as a seller and provide potential buyers with the necessary information to make informed decisions. From stigmatized properties to pest infestations, lead-based paint, and environmental hazards, it is essential to disclose relevant details and maintain open communication throughout the selling process. By doing so, you can ensure a smooth and successful transaction for all parties involved.
