Without going into another code, is the occupancy a residential occupancy? Does your community development plan allow for office in single family homes?
If you're not changing from and R to a B classification what is your question. How many new homes don't have home office's? Just because this one adds a waiting room, doesn't really increase the risk or occupancy. I can't see a shrink with 3 or four nurses, a receptionist and 10 or 12 patients backed up. Heck we just did a group home for "Challenged" clients with 13D as required by NFPA 101. You may have one or two 'challenged people there at one time but certainly not 10. So two head 13D is ok in my opinion. Now onto the Codes. IRC 419.5 419.5 Fire Protection: the live/work unit shall be provided with a monitored fire alarm system where required by Section 907.2.9 and an automatic sprinkler system in accordance with Section 903.2.8 903.2.8 Group R. An automatic sprinkler system installed in accordance with Section 903.3 shall be provided throughout all buildings with Group R fire area. (903.3 allows 13D) 903.3 Installation requirements. Automatic sprinkler systems shall be designed and installed in accordance with Sections 903.3.1 through 903.3.7. 903.3.1.3 NFPA 13D sprinkler systems.

There is a new section 419 that addresses Live/Work situations, to which this would apply. Try going on to the web site and see what they call for.
