Detached garage cost by metro in Connecticut
2 of the 5 metros sit above the statewide midpoint of $45,400, and the top-to-bottom gap is 3%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

|---|---|---|---|
| Bridgeport, CT | $30,700 – $61,700 | $46,200 | +2% |

When Connecticut weather lets you build
Season matters for detached garage. For each Connecticut metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for pouring concrete.
Bridgeport has the longest comfortable season of the metros we cover in Connecticut at 7 months (April through October); Norwich has the shortest at 6 (May through October). Rainfall runs from 42 inches a year in New Haven to 52 inches in Norwich.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Hartford | 20 | 85 | 43 | 6: May through October |

Connecticut labor market for detached garage
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 5 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.11 for Connecticut.
For carpenters (47-2031, weighted 45%) the local median is $30.80 an hour, which is 6% above the national $29.12. The middle half of them earn between $27.66 and $38.86 an hour. BLS counts 5,160 of them working in the state, 30.4 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $28.03 an hour, 24% above the US median of $22.66. The middle half of them earn between $22.92 and $34.98 an hour. About 7,360 work in the state. That is 43.4 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $28.19 an hour, which is in line with the national $27.41. The middle half of them earn between $23.34 and $31.41 an hour. BLS counts 610 of them working in the state, 3.6 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $37.28 an hour, 23% above the US median of $30.38. The middle half of them earn between $27.91 and $45.71 an hour. About 7,710 work in the state. That is 45.5 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For roofers (47-2181, weighted 10%) the local median is $29.84 an hour, which is 12% above the national $26.65. The middle half of them earn between $24.80 and $44.93 an hour. BLS counts 790 of them working in the state, 4.7 for every 10,000 jobs (US: 8.7), so the local bench is thinner than average.
A crew paid at the 75th percentile for carpenters ($38.86 an hour) would add about $2,700 to the statewide midpoint; one at the 25th percentile ($27.66) would take off about $1,050. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 1,696,170 jobs across Connecticut (May 2025), which is 1.1% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 45% | $27.66 | $30.80 | $38.86 | $29.12 | 1.06 | state |
