how much is the bldg. permit fee?

hello everyone.I' m new here.I'm interested to join this group cause you know i like designing house but i did not finish my study.thanks for letting me join the group.wen, we have an existing1-storey house but we have to extend for bout 25sq.m. with a budget of 80,000.Do you know how much it will cost for the bldg. permit?

Assuming its just a room without a toilet, the bldg. permit fee + fire fund will cost more or less P 855.00....so be sure to secure first a bldg. permit before you will construct because it will cost more than that of the estimated cost for the penalty (surcharge & administrative fines).
Welcome to our group.

thank you rowena.Have a nice day.
