Which type of disclosure is commonly made, though not mandatory, if relevant conditions exist?

Mold disclosure is commonly made by sellers and landlords in real estate transactions, even though it is not mandatory under California law. This practice stems from the growing awareness of the health risks associated with mold and its potential to cause significant property damage. When a property is known to have experienced moisture issues, water leaks, or previous mold problems, providing a disclosure about mold is not only responsible but also helps maintain transparency with potential buyers or tenants.

While other types of disclosures, such as lead paint and radon disclosures, have more defined legal requirements, mold disclosures are often completed as part of a seller's duty to inform buyers about the property’s condition. This practice reflects the principle of full information disclosure, promoting safety and preventing future liability.
