Whenever the enforcement officer determines that there is or has been a violation of any provisions of this chapter, he shall give notice of such violation to the person, persons or entities responsible therefor under this chapter. Such notice shall be in writing and shall include a concise statement of the reasons for its issuance. Such notice shall be deemed to be properly and sufficiently served if a copy thereof is sent by registered or certified mail to the last known address of the person or entity upon which the same is served, as shown by the most recent tax lists of the municipality, or if a copy thereof is handed to said person or persons or a copy thereof is left at the usual place of abode or office of said persons or entities. Notice shall be given as aforesaid within or without the municipality. The notice shall also state that unless the violation is abated, removed, cured, prevented or desisted from within 10 days of the date of service of such notice (exclusive of the date of service), a summons shall issue for such violation. The enforcement officer may, at the time he issues the notice, extend the period for compliance with the notice of violation for a period in excess of the aforesaid 10 days if, in his judgment, the abatement, removal, prevention, cessation or cure of the condition cannot reasonably be effected within the ten-day period; and in such cases the enforcement officer shall state such reasonably required extended period in the notice, which shall then be applicable instead of the aforesaid 10 days. In the event the violation is not abated, removed, cured, prevented or desisted from or otherwise fully remedied within said ten-day period or within such extended period as set forth in the notice pursuant to the foregoing, a summons shall be issued against the person, persons or entity or entities so notified.
