New Haven, CT
New Haven building permit fees
A New Haven building permit is priced from the cost of construction on one of two linear tables:
$50.26 for the first $1,000 plus $27.26 per additional $1,000 for 1&2-family residential work, or $55.26 plus $35.26 per $1,000 for 3+ family, commercial and mixed-use projects. A $50,000 house prices $1,386.00; the same cost on a commercial project prices $1,783.00.
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.
| Component | Formula | Applies when | Range |
|---|---|---|---|
| Commercial permit ($55.26 for the first $1,000 + $35.26 per additional $1,000)Permit fee | $55.26 + $35.26 per $1,000 of project valuation above $1,000, or fraction thereof | Occupancy is not residential | — |
| Residential permit ($50.26 for the first $1,000 + $27.26 per additional $1,000)Permit fee | $50.26 + $27.26 per $1,000 of project valuation above $1,000, or fraction thereof | Occupancy is residential | — |
A real permit fee is these components added together. The department’s final calculation is the one that applies — this is the schedule it will be based on.

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.
- Commercial permit ($55.26 for the first $1,000 + $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.
Residential table: $50.26 for the first $1,000 plus 119 x $27.26 = $3,243.94; total $50.26 + $3,243.94 = $3,294.20 — the table's own printed row at $120,000.
The same $120,000 declared on a 3+ family or commercial project would price $55.26 + 119 x $35.26 = $4,251.20. The residential C/O adds $50.00 for the first new unit when the work finishes.
What is different in New Haven
Both tables are perfectly linear, which makes the fee exactly predictable: the residential table adds $27.26 with every completed thousand ($295.60 at $10,000, $1,386.00 at $50,000, $4,384.60 at $160,000), and the commercial table adds $35.26 ($372.60 at $10,000, $1,783.00 at $50,000). The 26-cent endings carry Connecticut's state code-education surcharge — $0.26 per $1,000 — already inside the printed totals, so nothing is added on top.
Reading a fee is one multiplication: count the thousands above the first, multiply by the per-thousand step, and add the first-thousand base. A $25,000 addition on a 1&2-family house is $50.26 + 24 x $27.26 = $704.50 — the table's own printed row.
The same page prices the trades from these tables and protects the estimate side with Minimum Acceptable Cost sheets: the Building Department will not accept a cost declaration below its printed floors (a 200 A residential electrical service counts as $12,000 of work; a full bathroom counts as $5,000 of plumbing). Certificates ride separately: $50.00 for the first residential unit plus $30.00 each additional, $55.00 per 20,000 sq ft commercial, $30.00 for a Certificate of Approval where no C/O applies.
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 building-permit fee from its two schedules. It excludes:
- Certificates of occupancy ($50.00 first residential unit + $30.00 each additional; $55.00 per 20,000 sq ft commercial + $35.00 per additional 10,000) and the $30.00 Certificate of Approval.
- Demolition fees, priced on the City's separate demolition schedules for whole-structure teardowns.
- Sign permits, which the fee-schedule line names on the same tables but which are their own application.
- Plan review — neither schedule publishes a plan-review percentage, so none is charged.
- The state education surcharge as a separate component — the $0.26-per-$1,000 rider is already in the printed totals.
Common questions
How much is a building permit in New Haven, Connecticut?
$50.26 for the first $1,000 of construction cost plus $27.26 per additional $1,000 for 1&2-family residential work; $55.26 plus $35.26 per $1,000 for 3+ family, commercial and mixed-use. A $50,000 house prices $1,386.00.
Why do the fees end in 26 cents?
The .26 endings carry Connecticut's state code-education surcharge of $0.26 per $1,000 of construction cost. It is already included in the printed totals — you do not add it separately.
How is the fee calculated for a cost between thousands?
Partial thousands read up to the table's next completed thousand, matching the printed rows. A $25,500 project prices at the $26,000 row.
Do electrical and plumbing permits use the same table?
Yes — the Building Department's page prices Building, Sign, Electrical, Plumbing and HVAC permit fees from the same two schedules, with the commercial table applying to 3+ family and mixed-use work of any trade.
What is a 'Minimum Acceptable Cost'?
The Building Department's floor on the cost estimate your permit is priced from — not an extra fee. A 200 A residential electrical service counts as $12,000 of work, a full bathroom as $5,000 of plumbing, a water heater as $1,100.
How much is the certificate of occupancy?
Residential: $50.00 for the first new unit and $30.00 for each additional. Commercial: $55.00 per 20,000 sq ft plus $35.00 for each additional 10,000. Where no C/O is required, a Certificate of Approval is $30.00.
Is there a plan review fee?
Neither fee schedule publishes a plan-review percentage; the permit fee from the cost table is the whole printed charge.
What about demolition?
Whole-structure demolition follows the City's own demolition fee schedules, separate from the construction fee tables.
When did these schedules take effect?
The fee-schedule PDFs carry a September 29, 2020 document date and are the schedules the Building Department's applications page links today; the plumbing minimum-cost sheet carries a September 6, 2024 revision date.
How do I apply?
Through the Building Department (Office of Building Inspection & Enforcement), 200 Orange Street, 5th Floor — the applications page links the online permit route and the fee schedules.
Does solar work have its own fee?
Solar panel installations count as electrical work with a minimum acceptable cost of $4 per watt (a 5.6 kW system counts as $22,400 of work), then price from the normal fee table.
Is the fee different for additions versus new construction?
No — both read the same cost tables. Only the occupancy class (1&2-family residential versus 3+ family, commercial, mixed-use) selects which table applies.
