Which New Mexico city is cheapest for home addition?
1 of the 3 metros sit above the statewide midpoint of $54,500, and the top-to-bottom gap is 7%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (300 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Albuquerque, NM | $36,300 – $73,600 | $55,000 | +1% |
| Santa Fe, NM | $35,600 – $72,200 | $53,900 | −1% |
| Las Cruces, NM | $33,800 – $68,500 | $51,200 | −6% |
Wages behind the New Mexico number
New Mexico's labor line is priced from 6 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.94 times the national level.
Carpenters (47-2031), 50% of the weighting: a median of $28.71 an hour, in line with the US median of $29.12. The middle half of them earn between $22.67 and $30.44 an hour. About 3,630 work in the state. That is 41.7 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 $23.67 an hour, 14% below the US median of $27.41. The middle half of them earn between $21.72 and $28.85 an hour. About 1,540 work in the state. That is 17.7 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 $28.07 an hour, which is 8% below the national $30.38. The middle half of them earn between $22.46 and $35.28 an hour. BLS counts 5,020 of them working in the state, 57.6 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 $29.54 an hour, 4% below the US median of $30.67. The middle half of them earn between $21.72 and $37.60 an hour. About 2,830 work in the state. That is 32.5 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $25.91 an hour, which is 9% below the national $28.33. The middle half of them earn between $21.00 and $36.06 an hour. BLS counts 580 of them working in the state, 6.7 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $21.78 an hour, 18% below the US median of $26.65. The middle half of them earn between $18.49 and $26.94 an hour. About 1,160 work in the state. That is 13.3 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A crew paid at the 75th percentile for carpenters ($30.44 an hour) would add about $1,150 to the statewide midpoint; one at the 25th percentile ($22.67) would take off about $3,950. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 870,970 jobs across New Mexico (May 2025), which is 0.6% of US employment.

New Mexico seasons and home addition
Weather decides when digging and ground work can happen, and New Mexico is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.
Albuquerque has the longest comfortable season of the metros we cover in New Mexico at 7 months (March through May and August through November); Santa Fe has the shortest at 6 (May through October). Rainfall runs from 9 inches a year in Albuquerque to 13 inches in Santa Fe.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Albuquerque | 26 | 91 | 9 | 7: March through May and August through November |
| Las Cruces | 30 | 96 | 9 | 7: February through May and September through November |
| Santa Fe | 18 | 86 | 13 | 6: May through October |
