Nobody was reported injured.
The Orange County Register ( http://bit.ly/1ntcJ7g) reports that several rooms at the Dana Point Harbor Inn were evacuated after the blaze broke out Tuesday night.
The fire was discovered shortly after 8 p.m. in a section of the hotel being renovated.
It took more than 80 firefighters about an hour to douse the flames.
Orange County Fire Authority Capt. Steve Concialdi says the blaze was mostly contained to two rooms.
Several other rooms sustained smoke and water damage, however.
The fire's cause is under investigation.
The beach resort community of Dana Point is about 60 miles southwest of Los Angeles.
