Weighted together, McAllen wages are 0.72 times the national level. Labor makes up about 61% of the midpoint estimate (67% at national prices).
On the materials line, the BEA goods price index for the McAllen metro is 93.8 (US = 100). The midpoint materials bill for 300 sq ft comes to $16,900, compared with $18,000 at national prices. Permit and inspection fees are scaled by the broader index (85.9) and land at $430 to $1,700.
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 McAllen. The wage table below marks each row.

Climate in McAllen: timing your home addition job
We use NOAA's 1991-2020 climate normals for Mcallen Miller Intl Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
October through April is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in McAllen (7 of 12 months). May, June, July, August and September have an average daytime high of 90°F or more.
McAllen gets about 22 inches of precipitation in a normal year. The wettest months are June, September and October (4.6 inches in September). Inside the workable window, January and February are the driest, at 0.8 and 0.7 inches. The station averages about 177 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.

McAllen labor market for home addition
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 McAllen is 0.72 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $19.97 an hour, which is 31% below the national $29.12. The middle half of them earn between $17.40 and $21.94 an hour. BLS counts 310 of them working in the area, 10.4 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 $18.57 an hour, which is 32% below the national $27.41. The middle half of them earn between $15.25 and $22.03 an hour. BLS counts 390 of them working in the area, 13.1 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 $22.56 an hour, 26% below the US median of $30.38. The middle half of them earn between $18.13 and $28.33 an hour. About 670 work in the metro. That is 22.6 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 $22.17 an hour, which is 28% below the national $30.67. The middle half of them earn between $18.38 and $27.04 an hour. BLS counts 360 of them working in the area, 12.1 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 McAllen metro, so we used the Texas statewide median: $22.88 an hour against $28.33 for the US. The middle half of them earn between $19.28 and $28.09 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the McAllen metro, so we used the Texas statewide median: $22.13 an hour against $26.65 for the US. The middle half of them earn between $18.00 and $25.78 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($21.94 an hour) instead of the median, the labor line grows by about $1,300. At the 25th percentile ($17.40) it shrinks by about $1,700. The total moves by 2.8% or 3.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 296,700 jobs in the McAllen-Edinburg-Mission area. That makes it the 86th largest of the 300 metros we cover, with 0.19% of US employment.
