Landmark status or a location in a historic district poses an extra challenge for buildings in need of post-hurricane repairs. Those repairs must be reviewed by the Landmarks Preservation Commission if they involve exterior changes?and the LPC office is still without power. But the LPC website has some quick guidelines: "f you are a property owner or manager and need to make emergency repairs, stabilize the condition first and follow up with us when possible for a permit. If your repair involves the removal or repair of an architectural feature, please photograph it, if possible, and store it safely." [NYT]
