Hamden, CT Solar Energy: Panel Permits (2026)

Section 150.07 of Hamden's building code amendments requires a separate permit fee for electrical work in addition to the base building permit fee set in § 150.06. General electrical, plumbing, heating, air-conditioning, refrigeration, well pump, ventilating, exhaust and swimming pool work is billed at $24 for the first $1,000 of estimated cost and $24 for each additional $1,000 or fraction of it, but § 150.07(B) singles out solar electrical work for its own rate of $4.50 per kilowatt (PKW) of installed capacity rather than the per-$1,000 cost formula used for other trades.

That permit is issued by the Building Department, which under § 150.04 will not approve any electrical or building application until the applicant certifies there are no delinquent property taxes or sewer use fees on the property. Section 150.17 layers on a separate, older incentive: a solar heating or cooling system installed on a building whose construction began on or after October 1, 1976, and before October 1, 1991, is exempt from local property tax under Conn. Gen. Stat. § 12-81(56) for the first seven assessment years, to the extent the solar equipment raises the assessed value above what a conventional system would. That exemption predates the current solar-panel electrical permit and does not itself waive the § 150.07(B) permit fee.
