Florida Statute (713.23) states: a lienor is required, as a condition precedent to recovery under the bond, to serve a written notice of nonpayment to the contractor and the surety not later than 90 days after the final furnishing of labor, services, or materials by the lienor. A written notice satisfies this condition precedent with respect to the payment described in the notice of nonpayment, including unpaid finance charges due under the lienor's contract, and with respect to any other payments which become due to the lienor after the date of the notice of nonpayment. The time period for serving a written notice of nonpayment shall be measured from the last day of furnishing labor, services, or materials by the lienor and shall not be measured by other standards, such as the issuance of a certificate of occupancy or the issuance of a certificate of substantial completion.
The failure of a lienor to receive retainage sums not in excess of 10 percent of the value of labor, services, or materials furnished by the lienor is not considered a nonpayment requiring the service of the notice provided under this paragraph. If the payment bond is not recorded before commencement of construction, the time period for the lienor to serve a notice of nonpayment may at the option of the lienor be calculated from the date specified in this section or the date the lienor is served a copy of the bond. However, the limitation period for commencement of an action on the payment bond as established in paragraph (e) may not be expanded
