Where the Gulfport price comes from
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, Gulfport wages are 0.82 times the national level. Labor makes up about 63% of the midpoint estimate (67% at national prices).
Materials are scaled with BEA's regional price parity for goods. Gulfport 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 90.0: $450 to $1,800.
Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Gulfport. The wage table below marks each row.

Who does the work: Gulfport 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 Gulfport the blend is 0.82.
Carpenters (47-2031), 50% of the weighting: a median of $23.78 an hour, 18% below the US median of $29.12. The middle half of them earn between $21.51 and $25.23 an hour. About 530 work in the metro. That is 33.5 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 $18.30 an hour, 33% below the US median of $27.41. The middle half of them earn between $17.02 and $23.04 an hour. About 100 work in the metro. That is 6.3 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $30.02 an hour, which is in line with the national $30.38. The middle half of them earn between $28.41 and $30.02 an hour. BLS counts 2,010 of them working in the area, 127.0 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 $30.31 an hour, in line with the US median of $30.67. The middle half of them earn between $23.38 and $30.31 an hour. About 1,240 work in the metro. That is 78.3 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Gulfport metro, so we used the Mississippi statewide median: $17.94 an hour against $28.33 for the US. The middle half of them earn between $14.46 and $21.42 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Gulfport metro, so we used the Mississippi statewide median: $21.61 an hour against $26.65 for the US. The middle half of them earn between $17.53 and $23.56 an hour.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $950 to the midpoint estimate; the 25th percentile takes off about $1,500. That is a swing of roughly 3.0% to 1.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Gulfport-Biloxi has 158,310 jobs in total (BLS, May 2025), ranking 149th by size among the 300 metros on this site.
