Quality of janitor service evaluated on beauty of sights in the building is periodically reported to the building owner by a maintenance company. Therefore, standardization of the evaluation methods is required to make the evaluation reliable for the building owners. For this purpose, the present study analyzed 959 reports by inspectors who were accredited by Japan building maintenance association. The results showed that total score on beauty was proportionally correlated with the score of a toilet, and can be estimated from the cleaning floor area in the office building which were built before 25 years ago.
