Property owners are responsible for submitting documentation of their inspection findings and maintenance activities annually before the start of the rainy season (October 1st). Beginning in July, the County mails notification letters to property owners. In accordance with Section 67.812(b) of the County Code of Regulations, if property owners do not respond to the notifications, the County may initiate an enforcement investigation or follow-up inspection.
