About the building
443 4th Street is a small mixed-use condominium with two full-floor residences above commercial space. Known as The Carriage House, it has an unusually broad living-room frontage for an apartment in this part of Park Slope. Residential condominium transfers extend back to the late 1990s. The current division places the commercial space and each of the two apartments on separate tax lots, with the homes assessed in Class 2.
The residential layouts include two bedrooms and two bathrooms, with living areas across the front and bedrooms toward the rear. Large windows and a south-facing balcony open the principal rooms toward Fourth Street. Central air conditioning and in-unit laundry have been incorporated into renovated interiors. Residents also have access to a roof deck. Stairs serve the residential floors, and the building has an intercom entry system.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00983-7501) and verified listing data.

What to know if you’re buying
Two residences share a building with commercial ownership. The commercial lot adds a separate interest in decisions about the roof, structure and common services. The condominium's allocation of those expenses matters more than simply dividing a bill between the two apartments. Its mixed-use composition and small residential inventory may also narrow the lenders willing to finance a purchase here.

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.
