Certain buildings in the City of Philadelphia require periodic inspections. These inspections are performed by licensed inspection companies. Buildings that contain fire sprinkler systems or hard-wired fire alarm systems must have these systems inspected annually. Buildings over 60 feet must have their façade inspected every five years. Buildings with fire escapes or private bridges must have these structures inspected every five years. Non-vacant piers must be inspected every three years. The Department of Licenses and Inspections collects certifications documenting the conditions of these structures and enforces the requirements that property owners file these certifications with the Department and repair any structural issues or system deficiencies identified during the corresponding inspection. This dataset contains records related to these building certifications.
