Provided that selling or leasing a lot is not specifically prohibited by recorded covenant, it is unlawful to restrain the owner of a lot in a subdivision from offering such lot for sale or lease or from selling or leasing such lot. Any deed restriction or recorded covenant that creates a right of first refusal in excess of 30 days or creates a sales restraint that denies lot owners the right to post for-sale signs of reasonable size is null and void.
