It was investigated posing the problem: What is the level of deterioration and architectural degradation in the  cultural heritage typologies in the road axis of the avenue Giráldez de Huancayo? And the objective was to determine the levels that exist between the variables: deterioration and architectural degradation and the cultural heritage typologies in the road axis of the avenue Giráldez de Huancayo. The hypothesis was proposed that the level of deterioration and architectural degradation in the monumental heritage typologies is high in the road axis of the Giráldez avenue of Huancayo, for which two research scopes were developed, the first one was quantitative descriptive and the second Had a basic qualitative level, and was characterized as transverse and non-experimental. The research instrument that I used was the observation sheet, which was evaluated for validity with the Kappa Index of Fleiss, which determined a value for both variables of 0.79 (Acceptable agreement) and the reliability test detailed the Alpha Coefficient of Cronbach whose measure for both variables was 0.81 (High value). The sample used was intentional non-probabilistic, because 45 cultural heritage typologies were identified in the study area to operate the observation sheet. The results determined a high level of significance among the studied variables; Commercial and service use with 0.95; The contemporary constructive technologies with 0.96 and the regular state of conservation with 0.98. It was determined that there is a high level of significance between the system of the variables: deterioration and architectural degradation and monumental heritage typologies, and it was agreed that the use of land especially commercial and services, show a high level of significance with 0.95.
