A Private Pricing Opinion — what your apartment at The Santa Monica would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
The Santa Monica was designed and built by A. B. Kight as an early-twentieth-century apartment house near the Hudson River. A contemporary architectural publication described suites of four, five and six rooms. The six-story building now operates as a 36-residence cooperative with elevator access, a resident superintendent and an entrance set back from the sidewalk.
The approach is part of its character. Decorative fencing and globe lights frame the entry, with a paved forecourt leading to the main door. The building's broad frontage and comparatively low height distinguish it from the taller apartment houses around the West Seventies.
Its apartment inventory retains larger room arrangements alongside renovated two-bedroom plans and top-floor homes with private roof space. Riverside Park is close to the west, while the Broadway transit corridor is inland at 72nd Street. The cooperative conversion dates to 1982.
Architecture and unit composition
The original architectural description records a frontage of approximately 122 feet and a depth of about 67 feet six inches. Those dimensions supported several apartment sizes within one floor, from four-room suites to larger six-room arrangements. The building's name appeared in that contemporary publication, establishing the Santa Monica identity early in its history.
The recessed entrance creates a transition between sidewalk and lobby. Iron fencing and paired lights mark the approach, and the exterior spreads laterally across a substantial part of the block. The elevator serves six stories of apartments.
Present layouts include two-bedroom homes with a separate dining area, larger plans with more extensive circulation, and upper apartments with private roof terraces. Recorded interior areas include homes around 825 to 1,100 square feet and larger residences of roughly 1,250 to 1,500 square feet. The original room-count variety therefore remains visible in the resale inventory.
A top-floor home with private roof space is a different configuration from a conventional apartment on the same floor. Outdoor area is separate from the enclosed interior, and the route between the apartment and terrace affects its use. Other homes offer the same building location and services without private outdoor space.
Some interiors preserve traditional room divisions, while renovations have opened kitchens or reworked dining areas. In-unit laundry appears in the apartment inventory alongside the building's central laundry room. A renovated home can therefore have a materially different service arrangement from an apartment retaining its older plan.
Building operations
A live-in superintendent, central laundry and bicycle and private storage form the building's practical service program. Elevator access is particularly useful for the upper residences and roof-adjacent apartments. Private storage and private roof rights are distinct interests and should be identified separately in a purchase.
The cooperative permits pets and considers pied-à-terre ownership and sublets, with board approval required for leasing. Its stated minimum down payment is 25 percent, subject to current confirmation. The building's ownership structure is a cooperative corporation, with apartment shares and proprietary leases.
The property is in tax Class 2 and has no building-wide abatement. The built floor-area ratio slightly exceeds the residential allowance shown for the mapped R8B district. It is not designated by LPC, although historic districts cover other properties in the surrounding West Seventies.
Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
