What shapes a project in Philadelphia
Local conditions worth knowing before scope and budget are set.
Rowhouses with low-slope roofs
The City Planning Commission's 2008 Rowhouse Manual notes that most rowhouse roofs look flat but are gently sloped toward a drain, and that the kitchen is often in a one-story addition at the rear of the house. Expect roof drainage, flashing and rear-addition conditions to shape many projects.
Party walls and shared structure
The Rowhouse Manual explains that party walls provide fire separation between neighbors and that some party walls carry floors and roofs. It advises consulting an architect or engineer before any change that could weaken them. Plan structural changes with this in mind.
Historic register properties
If a property is on the Philadelphia Register of Historic Places, the Historical Commission must approve work before L&I accepts the permit application. Review covers exterior changes such as facades, and interiors only when they are listed on the register.
