This chapter shall not apply to any building of the Township or extension thereof, or to the use of any premises by the Township, if the Township Commissioners shall, after a public hearing, decide that such building or extension thereof, or such use of any premises, is reasonably necessary for the convenience or welfare of the public; provided, that any municipal recreational building or use may be established by the Board of Commissioners at any location in the Township without holding such public hearing.

In interpreting and applying the provisions of this chapter, they shall be held to be the minimum requirements for the promotion of public health, safety, and general welfare. Where this chapter requires a greater width or size of yards, courts, or other open spaces, or requires a lower height of buildings or less number of stories, or requires a greater percentage of lot to be left unoccupied, or imposes other high standards than are required in any statute, other ordinance, or regulation, the provisions of this chapter shall govern. Wherever the provisions of any statute, other ordinances, or regulation requires a greater width or size of yards, courts, or other open spaces, or require a lower height of building, or a less number of stories, or require a greater percentage of lot to be left unoccupied, or impose other high standards than are required by this chapter, the more restrictive provisions of such statute, other ordinance, or regulation shall govern.
