Whenever an enforcement officer determines that there is or has been a violation of any provision of this chapter, he shall, upon approval of the Mayor or a member of the Board of Trustees, give notice of such violation to the person, persons or entities responsible therefor. 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 assessment roll of the Village, or a copy thereof is personally delivered (as if a summons) to said person or persons or a copy thereof is left at the usual place of abode or office of said person or entity. Notice shall be given as aforesaid within or without the Village. The notice shall also state that unless the violation is abated, removed, cured, prevented or desisted from within five days of the date of service of such notice, exclusive of the date of service, an appearance ticket shall be issued for such violation. The enforcement officer may extend the period for compliance stated in the notice of violation for a period in excess of the aforesaid five days if, in his judgment, the abatement, removal, prevention, cessation or cure of the condition violated cannot reasonably be effected within the five-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 five days.
