The Underground Storage Tank Disclosure is a general disclosure document that contains background information explaining what an Underground Storage Tank (UST) is, and why you want to be aware of if the property you are considering purchasing might have a UST.

The Underground Storage Tank Disclosure is a *general* disclosure. The disclosure does not contain property specific information, but it does contain important information that you should read at your convenience. This disclosure is often provided in conjunction with an Underground Storage Tank Inspection, which we will discuss separately.

Underground Storage Tanks were typically used in San Francisco to store heating oil. While they are more common in older neighborhoods on the northern side of town, they have been found scattered across the city.

Our understanding of state law is that it requires the seller to remove and remediate an underground storage tank. However, there is no way to know if you have a UST unless you have an Underground Storage Tank inspection, which is typically a visual inspection performed at the exterior of the home (in other words, you don’t need to go inside to inspect for a tank) performed by a company that specializes in underground storage tank inspections.

As a buyer, you want to make sure that there is no underground storage tank, or that if there is a tank it is discovered before you are the property owner. These inspections make the most sense on single family homes. For recently built condominiums that had to excavate below ground as part of their construction process they would have mot likely discovered and removed any tanks during construction. That said, we’ve heard of one large condo building (it was previously a hospital, converted to condos) where a diligent buyer found USTs – and then the HOA had to have them removed!
