On the materials line, the BEA goods price index for the Florence metro is 96.3 (US = 100). The midpoint materials bill for 300 sq ft comes to $17,300, compared with $18,000 at national prices. Permit and inspection fees are scaled by the broader index (86.8) and land at $430 to $1,750.
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 Florence. The wage table below marks each row.

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 Florence is 0.83 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $23.68 an hour, which is 19% below the national $29.12. The middle half of them earn between $19.36 and $31.04 an hour. BLS counts 130 of them working in the area, 14.6 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $22.37 an hour, which is 18% below the national $27.41. The middle half of them earn between $18.25 and $22.37 an hour. BLS counts 110 of them working in the area, 12.4 for every 10,000 jobs (US: 13.3), so the local bench is about average.
Electricians (47-2111), 10% of the weighting: a median of $27.67 an hour, 9% below the US median of $30.38. The middle half of them earn between $23.22 and $29.11 an hour. About 240 work in the metro. That is 26.9 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 $27.00 an hour, which is 12% below the national $30.67. The middle half of them earn between $22.00 and $30.38 an hour. BLS counts 190 of them working in the area, 21.3 for every 10,000 jobs (US: 30.0), so the local bench is thinner than average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Florence 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) carry 10% of the labor weighting. BLS does not publish this trade for the Florence metro, so we used the South Carolina statewide median: $22.00 an hour against $26.65 for the US. The middle half of them earn between $18.26 and $25.37 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($31.04 an hour) instead of the median, the labor line grows by about $4,850. At the 25th percentile ($19.36) it shrinks by about $2,850. The total moves by 9.7% or 5.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 89,060 jobs in the Florence area. That makes it the 221st largest of the 300 metros we cover, with 0.06% of US employment.

When to schedule home addition in Florence
We use NOAA's 1991-2020 climate normals for Florence Rgnl Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
September through June is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Florence (10 of 12 months). July and August have an average daytime high of 90°F or more.
Florence gets about 45 inches of precipitation in a normal year. The wettest months are June, July and August (5.8 inches in July). Inside the workable window, February and November are the driest, at 3.0 and 2.6 inches. The station averages about 70 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.
