Halocho #1025 – Mezuza checking

The Torah commands us to put a Mezuza on all our doorposts except for the washroom. 

The Mezuza needs to be affixed to the top third of the doorpost - but not in the top 1 Tefach (~9 cm; 3.5"). 

Every Mezuza needs to be checked twice in seven years. (Some have the custom of checking their Mezuzot in Adar-א; this is slightly more frequent than twice in seven years, but it's easy to remember.) 

The Mezuzot on public buildings need to be checked only twice in 50 years.
