Where the Yuma price comes from
The wage side of the estimate leans on carpenters, who do 50% of the hours on a typical job. Their local median is $23.04 an hour. Add the other trades involved and the blended wage index for Yuma is 0.84 (US = 1.00), which puts labor at 64% of the total.
Materials are scaled with BEA's regional price parity for goods. Yuma 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 92.7: $460 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 Yuma. The wage table below marks each row.

The best months for home addition in Yuma
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Yuma Mcas (10 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Yuma are November through April: 6 of 12. Outside them, May, June, July, August, September and October have an average daytime high of 90°F or more.
Yuma gets about 3 inches of precipitation in a normal year. The wettest months are January, September and December (0.7 inches in September). Inside the workable window, April and November are the driest, at 0.1 and 0.2 inches. The station averages about 181 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.

Who does the work: Yuma 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 Yuma the blend is 0.84.
Carpenters (47-2031), 50% of the weighting: a median of $23.04 an hour, 21% below the US median of $29.12. The middle half of them earn between $18.42 and $27.42 an hour. About 260 work in the metro. That is 37.7 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $23.43 an hour, 15% below the US median of $27.41. The middle half of them earn between $22.45 and $27.10 an hour. About 130 work in the metro. That is 18.9 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 $28.28 an hour, which is 7% below the national $30.38. The middle half of them earn between $21.70 and $35.90 an hour. BLS counts 340 of them working in the area, 49.4 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $28.36 an hour, 8% below the US median of $30.67. The middle half of them earn between $21.75 and $31.97 an hour. About 170 work in the metro. That is 24.7 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $26.15 an hour, which is 8% below the national $28.33. The middle half of them earn between $23.49 and $29.00 an hour. BLS counts 50 of them working in the area, 7.3 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 Yuma 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 $2,900 to the midpoint estimate; the 25th percentile takes off about $3,050. That is a swing of roughly 6.0% to 5.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Yuma has 68,880 jobs in total (BLS, May 2025), ranking 262nd by size among the 300 metros on this site.
