New Haven electrical permit fees
An electrical permit in New Haven is priced from the Building Department's cost-of-construction tables — the same page prices Building
Sign, Electrical, Plumbing and HVAC permits from them. Residential electrical work reads $50.26 + $27.26 per $1,000; 3+ family and commercial work reads $55.26 + $35.26 per $1,000. The City's Minimum Acceptable Cost sheet fixes what a service or a solar job counts as.
How this fee is calculated
These are the components the schedule defines for this permit, as they applied on 2026-09-28. A component only applies to your project if its conditions match — read that column before assuming a figure. Want a figure for your own project? Estimate this fee with the permit fee calculator.

Fees that do not apply here
Listed so you can see what was considered and left out, rather than wondering whether something is missing. A rule can also be left out because it is not published for this permit at all, and that is stated where it matters.
- Electrical permit, commercial ($55.26 + $35.26 per additional $1,000) — This fee does not apply to the inputs provided.
Assumptions
- Calculated from 1 fee rule in effect on 2026-09-28.
- Amounts are rounded to the nearest cent, once, at the end of each component.
The Minimum Acceptable Cost sheet prices a single-family 200 A service at $12,000 of work — the estimate floor.
At the residential table: $50.26 + 11 x $27.26 = $50.26 + $299.86 = $350.12 — the printed row at $12,000.
(The calculator takes the declared cost directly; entering the $12,000 floor reproduces the sheet.)
What is different in New Haven
New Haven's electrical permit has no fee table of its own — the fee-schedule line on the applications page names electrical permits on the same two cost tables the building permit reads. The arithmetic is identical: $50.26 for the first $1,000 plus $27.26 per additional thousand on 1&2-family work ($55.26 / $35.26 on commercial), with the state's 26-cent education rider already inside the printed figures.
What the electrical side does have is the Minimum Acceptable Cost sheet, and it drives real money: the Building Department prices the permit from its floor of the *cost estimate*, not from a zero. A 100 A service counts as $1,900 of work ($54.26 at the residential table), a 200 A service $3,000 ($82.04), a single-family 200 A service $12,000 ($329.38), and solar counts at $4 per watt — a 5.6 kW system counts as $22,400, pricing $610.26. A kitchen gut counts as $3,200.
Certificates attach at the end: where the electrical work rides a building permit, the building's C/O already covers it; where a trade permit stands alone, the $30.00 Certificate of Approval applies after inspection.
What this figure does not include
Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.
Not included in these figures
This is the Building Department's electrical permit pricing from the cost tables. It excludes:
- The building permit for the project the electrical work belongs to, priced separately on the building page here.
- The Minimum Acceptable Cost sheet itself — it floors the cost estimate; it is not an additional charge.
- The $30.00 Certificate of Approval for stand-alone trade permits, and the C/O schedule for buildings.
- Plan review — the schedules publish no plan-review percentage.
- The state education surcharge as a separate component — already inside the printed totals.
Common questions
How much is an electrical permit in New Haven?
It follows the same cost tables as the building permit: $50.26 + $27.26 per $1,000 residential, $55.26 + $35.26 per $1,000 on 3+ family and commercial work.
What does a 200-amp service upgrade cost to permit?
The Minimum Acceptable Cost sheet prices a single-family 200 A service at $12,000 of work, which prices $350.12 at the residential table. Two-family and three-family services count as $15,000 and $18,000.
What is the minimum cost for solar?
$4 per watt — a 5.6 kW system counts as $22,400 of electrical work and prices $610.26 at the residential table.
Is there a separate electrical fee table?
No — the applications page prices Building, Sign, Electrical, Plumbing and HVAC permits from the same two schedules.
Why does the fee end in 26 cents?
Connecticut's state code-education surcharge of $0.26 per $1,000, already included in the printed totals.
How is the fee computed for commercial electrical work?
From the commercial table: $55.26 for the first $1,000 plus $35.26 per additional $1,000 — $372.60 at $10,000 of work.
Do I need a separate electrical permit if there's a building permit?
The trade permit is its own application; the Certificate of Approval fee ($30.00) is waived on trade permits whose work a correlating building permit has already paid the certificate for.
What does a kitchen gut count as?
$3,200 of electrical work per the Minimum Acceptable Cost sheet — $87.34 at the residential table.
Is there a plan review fee for electrical permits?
The fee schedules publish no plan-review percentage; the cost-table fee is the whole printed charge.
How do I apply?
Through the Building Department's applications page (Office of Building Inspection & Enforcement, 200 Orange Street, 5th Floor), which links the fee schedules and the minimum-cost sheets.
