Geography
Inwood is physically bounded by the Harlem River to the north and east, and the Hudson River to the west. It extends southward to Fort Tryon Park and alternatively Dyckman Street or Fairview Avenue farther south, depending on the source.

While Inwood is the northernmost neighborhood on the island of Manhattan, it is not the northernmost neighborhood of the entire borough of Manhattan. That distinction is held by Marble Hill, a neighborhood situated just north of Inwood, on what is properly the North American mainland bordering the Bronx. Marble Hill was isolated from Inwood and the rest of Manhattan in 1895 when the route of the Harlem River was altered by the construction of the Harlem River Ship Canal.

Geology
Inwood marble, a soft, white, metamorphic rock found in northern Manhattan, takes its name after the neighborhood. From the mid-17th to the late 18th century, commercial quarries dotted the area as the material was used for building construction. However, due to its susceptibility to erosion, builders eventually used alternate construction materials. Inwood marble was quarried for government buildings in lower Manhattan and Washington, D.C. Small pieces of marble can still be seen in the stone retaining walls around Isham Park.

The development of Inwood in the early 20th century resulted in the demolition of many rock outcroppings. However, several outcroppings still exist, including on Cooper Street between 204th and 207th Streets; at Broadway and West 216th Street; and in the garden of Holy Trinity Episcopal Church at Seaman Avenue and Cumming Street. The rock on Cooper Street contains a garden maintained by a nearby housing cooperative at 60 Cooper Street, which owns half of the rock.

The seismologically active Dyckman Street Fault runs east-west beneath the Dyckman Valley. As recently as 1989, activity of this fault caused a magnitude 2 earthquake.

Land use
Commercial retail uses are mainly located along Broadway, Dyckman Street and West 207th Street. In recent years Dyckman Street west of Broadway has become a popular entertainment district with many restaurants and lounges. Offices are typically located on second floors over retail, or in the neighborhood's sole office building (a converted telephone building) at Broadway and West 215th Street. Inwood also contains one of Manhattan's few remaining C-8 zoning districts, which concentrates automotive uses on the northern stretches of Broadway.

Industrial uses, including depots for subway (207th Street Yard), bus (Kingsbridge Bus Depot), and sanitation (Manhattan North), exist primarily along Sherman Creek, an inlet of the Harlem River. The creek and surrounding industrial area is bounded by Dyckman Street to the south, Tenth Avenue to the west, and 207th Street to the north. There has been an initiative among politicians over the last few years to re-zone this area for residential and commercial use, and to create public access to the waterfront. Utility company Consolidated Edison and the City of New York own some of the property in this area.



The major residential land use in Inwood is multifamily five- to eight-story prewar apartment buildings. New construction is rare. Most of the remaining detached and semi-detached houses on Manhattan Island are located in Inwood, nestled between apartment buildings. Adjacent to Sherman Creek is Inwood's public housing development, known as the Dyckman Houses and constructed in 1951.

Real estate
Inwood's real estate rents and values are sharply bifurcated between east and west. According to Manhattan Community Board 12, the districts east of Broadway are predominantly lower-income. This area is also more industrial and commercial and has fewer parks and street trees. Real estate values and rents are correspondingly lower than the area west of Broadway. Almost all of Inwood's co-ops and all of the private houses are located on the west side of Broadway. According to one study in 2019, Inwood had the lowest average rents in Manhattan.

In 2015, New York City began soliciting community comments on a major rezoning proposal for Inwood. The New York City Economic Development Corporation proposed to alter the area's 50-year-old current zoning plan by dividing Inwood into five sub-districts called "the tip of Manhattan", "Upland Wedge", "Upland Core", "Commercial U" and "Sherman Creek". Some of these sub-districts would be rezoned to encourage the construction of new commercial space and housing. A resident recalls being told by a city planner, "Don't think you can keep this nice neighborhood all to yourselves." The rezoning proposal has triggered much feedback from the community, including a sleep-in at Councilman Ydanis Rodriguez's office. In August 2018, the New York City Council approved a measure to rezone the neighborhood. The rezoning of Inwood allows for the construction of buildings of up to 30 stories in some areas targeted for redevelopment while introducing an 8 story height limit to many existing residential areas. Following the rezoning, over $610 million in real estate was purchased.
