Answers before you apply
STS professional fees vary by county, municipality, and filing complexity:
Government fees, insurance premiums, fingerprints, examinations, education, record requests, and other third-party costs are separate and may change. STS will provide a proposal separating professional fees from anticipated third-party expenses.
Current estimates are 2–4 months for Nassau County, 1–2 months for Long Beach, 1–2 weeks for Rockville Centre contractor-side requirements, 6–8 weeks for Suffolk County, and 1–2 weeks for East Hampton, Southampton, or Shelter Island. Timing can change based on agency workload, exam scheduling, insurance, missing documents, and applicant history.
Sometimes. Long Beach, East Hampton, Southampton, and Shelter Island maintain local requirements that may apply in addition to county licensing. Rockville Centre may require contractor insurance verification and separate trade credentials depending on the work. STS reviews the project location and scope to identify the applicable contractor-side path.
Suffolk County’s home improvement contractor process includes a written examination. STS can help organize the application and supporting requirements, but the applicant must complete any required exam and the County makes the licensing decision.
A criminal history does not automatically mean you cannot qualify. The agency may review the nature of the offense, how long ago it occurred, rehabilitation, and whether your disclosures and supporting records are complete. Never omit requested information. STS can help organize the application and supporting documents, but STS is not a law firm and cannot provide legal advice or guarantee approval.
Outstanding child-support obligations can affect licensing. Eligibility may depend on your current status, compliance with a payment arrangement, and the documentation requested by the licensing agency. STS can help you identify and organize the required records, but approval decisions remain with the agency.
