I have a 1/2 bath with a toilet and lav only. The bathroom does not have a window. The building was built in 1988. Does this 1/2 bath require an exhaust fan by 1988 Calif building code. The building was built and finaled by the city in 1988 without the exhaust fan. The bath does have a HVAC duct for heat from a FAU. Any help would be great.
