On the materials line, the BEA goods price index for the Binghamton metro is 99.7 (US = 100). The midpoint materials bill for 300 sq ft comes to $17,900, compared with $18,000 at national prices. Permit and inspection fees are scaled by the broader index (92.9) and land at $460 to $1,850.
Data note: 10% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Binghamton. The wage table below marks each row.
Why two Binghamton quotes can differ
Foundation
A foundation, framing, roofing and matching exterior finishes all have to be built before the interior work starts.
Type of addition
A new room is $125-$250 per sq ft; a bump-out $85-$200; an attic conversion $50-$150; a garage conversion $50-$200 (HomeGuide).
Plumbing and fixtures
Adding a bathroom or kitchen drives the price up the most.

Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 6 trades carry the job here, and each is compared with its US median. The weighted result for Binghamton is 1.09 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $29.81 an hour, which is in line with the national $29.12. The middle half of them earn between $24.27 and $36.54 an hour. BLS counts 400 of them working in the area, 41.2 for every 10,000 jobs (US: 43.1), so the local bench is about average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $29.98 an hour, which is 9% above the national $27.41. The middle half of them earn between $28.50 and $40.23 an hour. BLS counts 90 of them working in the area, 9.3 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 $36.86 an hour, 21% above the US median of $30.38. The middle half of them earn between $27.62 and $46.00 an hour. About 390 work in the metro. That is 40.2 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $42.30 an hour, which is 38% above the national $30.67. The middle half of them earn between $28.92 and $46.59 an hour. BLS counts 280 of them working in the area, 28.9 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Binghamton metro, so we used the New York statewide median: $29.46 an hour against $28.33 for the US. The middle half of them earn between $25.22 and $36.34 an hour.
For roofers (47-2181, weighted 10%) the local median is $28.75 an hour, which is 8% above the national $26.65. The middle half of them earn between $23.14 and $32.16 an hour. BLS counts 80 of them working in the area, 8.2 for every 10,000 jobs (US: 8.7), so the local bench is about average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($36.54 an hour) instead of the median, the labor line grows by about $4,400. At the 25th percentile ($24.27) it shrinks by about $3,650. The total moves by 7.3% or 6.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 97,030 jobs in the Binghamton area. That makes it the 207th largest of the 300 metros we cover, with 0.06% of US employment.

When to schedule home addition in Binghamton
We use NOAA's 1991-2020 climate normals for Binghamton (10 miles from the city center). These are 30-year monthly averages, not forecasts.
April through October is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Binghamton (7 of 12 months). January, February, March, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, November and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 142 days a year with a low at or below 32°F at this station.
Binghamton gets about 42 inches of precipitation in a normal year, including roughly 87 inches of snow. The wettest months are June, August and September (4.7 inches in June). Inside the workable window, April and October are the driest, at 3.6 and 3.8 inches. The station averages about 2 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.
