What Can a Handyman Do Without a License in Durham, Connecticut?

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed February 2026

In Connecticut, most “handyman” work that involves home repairs/renovations for 1–4 family residential property requires a Connecticut Home Improvement Contractor (HIC) registration through the Department of Consumer Protection (DCP)—there is not a broad handyman dollar-threshold exemption you can rely on. Separate state trade licenses (electrical, plumbing, HVAC, gas piping) are required for regulated work regardless of whether you are a handyman, and local building permits still apply in Durham (Middlesex County) for many common jobs.

✅ What You Can Do Without a License

• Assembling furniture, mounting TVs/shelves to existing framing (no structural changes) (researched)
• Door hardware replacement (knobs, deadbolts) and weatherstripping (researched)
• Replacing faucets/showerheads/toilets ONLY where it is a like-for-like swap and does not require moving/altering plumbing lines (still may need permit depending on scope) (researched)
• Replacing light fixtures/switches is typically considered electrical work and often requires a licensed electrician in CT—verify with Durham Building Department before offering it (researched)
