Reinstatement: Show the details (amounts are approximate)

After 3 years must reapply and retest. (CGS 20-335 text mentions 2 years; DCP pages and 21a-4 say 3 years.)

Fees change. Check the official site for the exact amount.

Why approximate?

Boards change fees often and some charge extra processing fees. We show a recent amount so you can plan.

Bond: Not required
Insurance: Not required
Reciprocity: Connecticut does not have reciprocal agreements with any other jurisdiction (DCP); applicants with an equivalent out-of-state license may apply via the 'equivalent out of state license' path and still take the exam.

Renewal fee ($150 contractor / $120 journeyperson) confirmed in both DCP page and CGS 20-335. No bond or insurance requirement found for the trade license.
