What is behind the Myrtle Beach number
Labor is 62% of the midpoint bill here, against 67% nationally. The mix of trades behind this job is carpenters (50%), cement masons and concrete finishers (10%), electricians (10%), plumbers, pipefitters and steamfitters (10%), drywall and ceiling tile installers (10%), roofers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Myrtle Beach the blended ratio comes out at 0.79.
Materials are scaled with BEA's regional price parity for goods. Myrtle Beach 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 93.6: $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 Myrtle Beach. The wage table below marks each row.

Myrtle Beach weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Myrtle Beach (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for digging, grading and setting material in the ground in Myrtle Beach: no month in the averages is cold enough (an average overnight low at or below freezing (32°F)) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
Myrtle Beach gets about 54 inches of precipitation in a normal year. The wettest months are July, August and September (6.8 inches in September). The station averages about 22 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.

What local crews earn in Myrtle Beach
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 Myrtle Beach the blend is 0.79.
Carpenters (47-2031), 50% of the weighting: a median of $22.96 an hour, 21% below the US median of $29.12. The middle half of them earn between $20.40 and $27.34 an hour. About 510 work in the metro. That is 34.9 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 $22.02 an hour, 20% below the US median of $27.41. The middle half of them earn between $19.44 and $30.23 an hour. About 110 work in the metro. That is 7.5 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 $24.62 an hour, which is 19% below the national $30.38. The middle half of them earn between $22.48 and $28.41 an hour. BLS counts 360 of them working in the area, 24.6 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 $23.24 an hour, 24% below the US median of $30.67. The middle half of them earn between $21.78 and $29.40 an hour. About 460 work in the metro. That is 31.5 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Myrtle Beach 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 $22.40 an hour, 16% below the US median of $26.65. The middle half of them earn between $17.74 and $24.62 an hour. About 60 work in the metro. That is 4.1 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 $2,900 to the midpoint estimate; the 25th percentile takes off about $1,700. That is a swing of roughly 3.4% to 5.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Myrtle Beach-Conway-North Myrtle Beach has 146,260 jobs in total (BLS, May 2025), ranking 157th by size among the 300 metros on this site.
