Why Jacksonville prices look the way they do
We price the labor side from BLS wage data for 6 trades: carpenters at 50%, cement masons and concrete finishers at 10%, electricians at 10%, plumbers, pipefitters and steamfitters at 10%, drywall and ceiling tile installers at 10%, roofers at 10%. Weighted together, Jacksonville wages are 0.86 times the national level. Labor makes up about 64% of the midpoint estimate (67% at national prices).
Materials are scaled with BEA's regional price parity for goods. Jacksonville is at 96.2 against 100 for the US, so a materials line of $18,000 nationally becomes $17,300 here (midpoint, 300 sq ft). Permits follow the all-items index of 99.5: $500 to $2,000.
The best months for home addition in Jacksonville
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Jacksonville Nas (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Jacksonville are September through May: 9 of 12. Outside them, June, July and August have an average daytime high of 90°F or more.
Jacksonville gets about 48 inches of precipitation in a normal year. The wettest months are June, August and September (7.3 inches in June). Inside the workable window, February and November are the driest, at 2.3 and 2.0 inches. The station averages about 97 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

Who does the work: Jacksonville trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Jacksonville the blend is 0.86.
Carpenters (47-2031), 50% of the weighting: a median of $24.30 an hour, 17% below the US median of $29.12. The middle half of them earn between $21.87 and $29.08 an hour. About 2,500 work in the metro. That is 32.6 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $23.68 an hour, 14% below the US median of $27.41. The middle half of them earn between $21.91 and $26.54 an hour. About 980 work in the metro. That is 12.8 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $28.02 an hour, which is 8% below the national $30.38. The middle half of them earn between $22.90 and $29.54 an hour. BLS counts 4,990 of them working in the area, 65.1 for every 10,000 jobs (US: 48.7), so the local bench is deeper than average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $28.33 an hour, 8% below the US median of $30.67. The middle half of them earn between $22.89 and $30.74 an hour. About 2,380 work in the metro. That is 31.1 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $23.92 an hour, which is 16% below the national $28.33. The middle half of them earn between $22.13 and $27.11 an hour. BLS counts 560 of them working in the area, 7.3 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $22.85 an hour, 14% below the US median of $26.65. The middle half of them earn between $18.27 and $28.35 an hour. About 1,400 work in the metro. That is 18.3 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,150 to the midpoint estimate; the 25th percentile takes off about $1,600. That is a swing of roughly 3.1% to 6.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Jacksonville has 765,930 jobs in total (BLS, May 2025), ranking 39th by size among the 300 metros on this site.
