On July 27, 2022, FINRA filed a proposed rule change with the SEC to make it easier for brokers to work from home.

The proposed rule will add a category termed a "Residential Supervisory Location" under FINRA Rule 3110 (Supervision) that will treat a private residence where an associated person engages in specified supervisory activities as a non-branch location, subject to certain conditions. A Residential Supervisory Location would become subject to inspections on a regular periodic schedule, generally at least every three years, rather than an annual inspection requirement.
