Quoting the manual page

 --dhcp-hostsdir=<path>
        This is equivalent to --dhcp-hostsfile, except for the following. The path MUST  be
        a  directory, and not an individual file. Changed or new files within the directory
        are read automatically, without the need to send SIGHUP.  If a file is  deleted  or
        changed  after  it has been read by dnsmasq, then the host record it contained will
        remain until dnsmasq receives a SIGHUP, or is restarted; ie host records  are  only
        added dynamically.
