Final answer:
While the question asks about the period for notifying homeowners after filing a lien by subcontractors, the provided information pertains to employer notification requirements under the WARN Act, which is unrelated. Subcontractors usually have to notify homeowners within a statutory timeframe, often 20-30 days, but it varies by jurisdiction.
Step-by-step explanation:
The question deals with the notification requirements set by law for subcontractors, suppliers, and laborers after filing a mechanic's lien at the County Registrar of deeds. It is important to note that this is a legal procedure and it varies based on jurisdiction. However, the information provided about requiring employers with more than 100 employees to provide written notice 60 days before plant closings or large layoffs pertains to the Worker Adjustment and Retraining Notification Act and is not directly related to the specifics of mechanic's liens and notification of homeowners.
Typically, in many jurisdictions, subcontractors, suppliers, and laborers must notify the homeowner within a statutory period after filing a lien, often within 20 to 30 days, but this number can vary based on local laws. For the exact period required, one would need to consult the relevant state's mechanic's lien statute or a legal professional. Unfortunately, the provided reference does not give us specific information regarding the mechanic's liens notification period.
