The Three Risks of the 'Gig Economy'

⚖️

Supplier Debt Lawsuits

Cheap contractors often rob Peter to pay Paul. When they default on lumber bills for your project, Seneca law allows suppliers to sue you directly for the balance.

🛑

Stop Work Orders

City inspectors patrol Seneca daily. Unpermitted work gets red-tagged immediately. You will pay **double permit fees** plus administrative fines to resolve it.

🏥

Bankruptcy Risk

A single injury on your property can exceed your homeowner's liability cap. Uninsured 'handymen' expose your personal savings to massive medical claims.

Permit Requirements

Most exterior projects in Seneca (Decks over 30", Fences over 6', Additions) require a building permit from the local building department. Always ensure your contractor pulls the permit in their name.
