Well not really, as a lot of apartments have Explosive GAS piped right

Both are Extremely Explosive, when mixed with air in the correct

You will find that from a legal perspective that natural gas piped in is
not at all the same as storing a tank of hydrogen. Natural gas and
propane are very highly regulated as to installation, equipment
attached, etc. Very different than your tank of H2 will be.
