The results of soil tests, visual inspections and mathematical models of 14 masonry houses belonging to a state programme called ‘Techo Propio’ (Own Roof), located in the city of Eten, Chiclayo province, Peru, are presented. In order to evaluate the damage to the houses, the probable causes of their predominant pathologies are determined.

Results show that in most of the houses the most affected structural elements are walls (4.31 %), followed by columns (2.79 %) and beams (2.24 %). The predominant pathologies are efflorescence (2.01 %), concrete spalling (0.62 %), fissures (0.51 %) and cracks (0.30 %), being aesthetically serious.

Through the studies and data collection of the masonry units, soil mechanics, wall density, and structural modelling, it is possible to determine the seismic risk to which the houses are subjected, with 57.1 % of the houses at high seismic risk and 42.9 % at medium seismic risk. This result demonstrates the vulnerability to which these houses are exposed in the event of a seismic event.
