Stucco is concrete. Generally, it has exterior exposure. Reinforcing in concrete exposed to weather is required to have 11/2" cover for protection against corrosion. Stucco is never installed with that amount of cover over nails and lath. Old stucco (1920's, and 1930's) will often be found with detachment from the framing due to corroded nails and lath. This condition is most commonly found near roof drains, adjacent to faucets that have had leaks over the years, and adjacent to irrigated planting areas. The metal elements corrode and break, and the stucco cracks, sags and bulges under its own weight. I believe that old stucco, even if it looks good and seems sound should be suspect since, even though it may not have failed under its own weight, it may be a seismic failure waiting to happen due to corroded elements that have lost most of their original strength.
