'permit' is the definition.
(putting up with is a kind of permiting)

'build hotel's beyond reason' is the wordplay.
I cannot quite understand how this works, but
'build' could be 'putup' (putting up is a kind of building) and 'putup' is located in the answer.
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is found in the answer.
