Doors and Windows Ordinance (Philadelphia, PA)
This is a legal requirement for the protection of doors and windows that obliges the owners of houses and buildings to keep them in good physical and functional condition, even if the properties are not in use or are abandoned.
The regulation also provides for notices to be sent to the owners in order to prevent illegal occupations and to disseminate social control and a greater perception of order in certain areas. The buildings are inspected every 35 days, and failure to comply with the improvements results in the imposition of significant fines of US$300/day.
