A real estate broker shall maintain a sign at each of the broker’s registered real estate offices prominently showing the name of the real estate business as registered with the commission. The required size, content, and location of signs under this section may be determined by the commission under regulations. The regulations must allow signs in offices located on premises with more restrictive sign requirements than would otherwise be applicable under the commission’s regulations to be considered to be in compliance with the regulations if the signs meet the requirements of the premises and the licensee submits a copy of the sign requirements of the premises to the commission.
