Bell began working on appraisals of environmental and asbestos damage in the 1980s. He has also assessed Chinese dry wall and sink holes. In 1992, Bell assessed the damages of the Rodney King riots in Los Angeles. After the riots, he decided to focus only on damaged properties. Bell created the Bell Chart, a rating system that categorizes the 10 types of detrimental conditions and their corresponding economic damages of properties in 1992. The system ranks properties from class 1 to class 10. In 1994, he began assessing stigmatized properties such as the damages of the Northridge earthquake and wildfires in Malibu, California. In 1997, he became the national director of the Real Estate Damages practice of Price Waterhouse. He left the firm in 1999, and co-founded Bell Anderson & Sanders with two partners. Bell works with properties that have been affected by crime, environmental contamination, construction defects and natural disaster. He has consulted on Nicole Brown Simpson's condominium; the Beverly Hills estate where Charles Manson's followers murdered Sharon Tate and four other people in 1969; the Rancho Santa Fe mansions where the bodies of 39 Heaven's Gate cult members were found, the house in Boulder, Colorado, where JonBenét Ramsey was killed; the home of Sandy Hook Elementary School shooter Adam Lanza; and the house of Las Vegas shooterStephen Paddock. He has also consulted on Hurricane Katrina; the Bikini Atoll in the Marshall Islands; the September 11 attacks at the World Trade Center; and the United Airlines Flight 93 crash site in Shanksville. Bell has traveled to Chernobyl, Hiroshima; to the World Trade Center site; and to Egypt, Jordan, Israel and West Bank to find comparisons in properties damaged by terrorist attacks. He has also traveled to Antarctica to interview scientists about climate change how it affects costs, such as insurance for home owners. The Appraisal Institute published Bell's book Real Estate Damages: Applied Economics and Detrimental Conditions in 2008. In 2011, Bell returned from Guam, where he consulted with landowners whose property included the cave where Shoichi Yokoi, a Japanese army sergeant, hid for 28 years, unaware that World War II had ended. The landowners opened a theme park on the property.
