Where the Lake Havasu City price comes from
Labor is 63% 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 Lake Havasu City the blended ratio comes out at 0.82.
Materials are scaled with BEA's regional price parity for goods. Lake Havasu City 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 94.1: $470 to $1,900.
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 Lake Havasu City. The wage table below marks each row.
Who does the work: Lake Havasu City 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 Lake Havasu City the blend is 0.82.
Carpenters (47-2031), 50% of the weighting: a median of $22.59 an hour, 22% below the US median of $29.12. The middle half of them earn between $21.26 and $28.17 an hour. About 330 work in the metro. That is 58.4 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $24.43 an hour, 11% below the US median of $27.41. The middle half of them earn between $23.45 and $27.81 an hour. About 160 work in the metro. That is 28.3 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $26.07 an hour, which is 14% below the national $30.38. The middle half of them earn between $21.75 and $29.90 an hour. BLS counts 390 of them working in the area, 69.0 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 $28.14 an hour, 8% below the US median of $30.67. The middle half of them earn between $21.49 and $31.23 an hour. About 210 work in the metro. That is 37.2 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $23.45 an hour, which is 17% below the national $28.33. The middle half of them earn between $20.51 and $26.44 an hour. BLS counts 60 of them working in the area, 10.6 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Lake Havasu City metro, so we used the Arizona statewide median: $22.76 an hour against $26.65 for the US. The middle half of them earn between $19.16 and $28.43 an hour.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,650 to the midpoint estimate; the 25th percentile takes off about $870. That is a swing of roughly 1.7% to 7.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Lake Havasu City-Kingman has 56,490 jobs in total (BLS, May 2025), ranking 299th by size among the 300 metros on this site.
