TREC Rule 1260-2-.01 (Supervision of Affiliate Brokers) states that a licensee may be affiliated only with a principal broker who is involved primarily in the real estate business and accessible during normal daytime working hours. In other words, a principal broker must devote his full time to the management of the real estate brokerage firm and supervision of affiliate brokers.
This rule also prohibits a principal broker from engaging a licensee who lives more than 50 miles from the brokerage firm's office. This prohibition will not apply if the principal broker demonstrates in writing to the TREC's satisfaction that the distance is not unreasonable and that the licensee can be adequately supervised. This prohibition, however, does not apply to property managers who are engaged exclusively in the leasing and management of rental properties.
