Where the Greenville 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, Greenville wages are 0.84 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. Greenville is at 96.3 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 93.3: $470 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 Greenville. The wage table below marks each row.
What local crews earn in Greenville
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 Greenville the blend is 0.84.
Carpenters (47-2031), 50% of the weighting: a median of $24.08 an hour, 17% below the US median of $29.12. The middle half of them earn between $21.49 and $29.52 an hour. About 1,340 work in the metro. That is 30.8 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 $24.29 an hour, 11% below the US median of $27.41. The middle half of them earn between $21.12 and $29.85 an hour. About 470 work in the metro. That is 10.8 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 $28.95 an hour, which is 5% below the national $30.38. The middle half of them earn between $23.34 and $34.16 an hour. BLS counts 1,670 of them working in the area, 38.4 for every 10,000 jobs (US: 48.7), so the local bench is thinner than average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $24.46 an hour, 20% below the US median of $30.67. The middle half of them earn between $22.45 and $30.61 an hour. About 960 work in the metro. That is 22.1 per 10,000 jobs, compared with 30.0 nationally, so expect fewer 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 Greenville metro, so we used the South Carolina statewide median: $21.80 an hour against $28.33 for the US. The middle half of them earn between $18.36 and $25.56 an hour.
Roofers (47-2181), 10% of the weighting: a median of $22.37 an hour, 16% below the US median of $26.65. The middle half of them earn between $17.90 and $25.38 an hour. About 170 work in the metro. That is 3.9 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,550 to the midpoint estimate; the 25th percentile takes off about $1,700. That is a swing of roughly 3.4% to 7.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Greenville-Anderson-Greer has 434,900 jobs in total (BLS, May 2025), ranking 58th by size among the 300 metros on this site.

Greenville gets about 47 inches of precipitation in a normal year. The wettest months are March, July and December (5.2 inches in July). Inside the workable window, September and October are the driest, at 3.5 and 3.2 inches. The station averages about 52 days a year at 90°F or above.
