Manhattan Landmark Work Starts With LPC
Manhattan owners and tenants in landmark buildings should check LPC before exterior work, storefront changes, or visible repairs begin.

In Manhattan, a simple exterior change can become an LPC question. The Landmarks Law requires permits before work that affects the exterior of a designated landmark property. Some interior work can also require review. Owners and project representatives, including architects, commercial tenants, and consultants, apply before work starts.
LPC says applications are filed through Portico. Staff decide which permit type is needed after review.
Before changing windows, signs, storefronts, doors, railings, or facade material, check landmark status and the LPC route.
