## Property Overview

Set on one of Park Slope’s most coveted, tree-lined blocks, this extraordinary historic brownstone at 509 3rd Street embodies the timeless elegance and architectural grandeur that define Brownstone Brooklyn. Built in 1899, this distinguished two-family residence—currently configured as an expansive single-family home—seamlessly blends original period craftsmanship with the warmth and scale of classic townhouse living. Located in the heart of Center Slope, the property offers a premier location squarely positioned within the highly coveted P.S. 321 elementary school attendance zone.

Ascend the stately stone stoop and enter into a world of timeless Brooklyn elegance, where the home's stunning allure and classic woodwork details immediately captivate. The grand entryway unfolds into an impressive parlor sequence defined by soaring ceilings, graceful proportions, and an abundance of natural light pouring through oversized windows. Rich original crown moldings frame each space with sophistication, while exquisite cherry and oak millwork showcases the unparalleled artistry of a bygone era. Gleaming original hardwood floors run continuously throughout, anchoring the home with warmth, character, and an unmistakable sense of historical authenticity.

Designed for both grand-scale entertaining and comfortable daily living, the residence features a highly practical layout where each of the upper bedrooms is beautifully and nicely sized, offering rare comfort, excellent closet potential, and grand proportions. Every floor presents a versatile canvas, whether envisioned as a trophy single-family masterpiece, an owner’s triplex paired with an income-producing rental, or a multi-generational residence. For those looking to maximize the property's footprint, the estate includes approximately 1,489 square feet of unused FAR, offering lucrative potential for a seamless vertical or rear expansion.

The broader stretch of 3rd Street where the house sits is itself historically notable. Historians and architectural writers frequently describe the blocks between 7th Avenue and Prospect Park West as among Park Slope’s grandest residential streets because of their unusual width, mature trees, and intact late-Victorian row houses.

Architecturally, 509 3rd Street is tied to a larger 1892–93 development associated with the nearby apartment building known as “The Annandale Apartments” at 203 7th Avenue, designed by architect Lewis Anderson. Preservation historians note that while the development originally included four brownstones on 3rd Street, 509 3rd Street is the only one of those original houses included within the Park Slope Historic District today. This makes the building a proud, singular part of the Romanesque Revival wave that transformed Park Slope after the opening of Prospect Park. A true testament to its meticulous stewardship, the lucky next owner of this property will be only the fourth owner to live here in over a century.

Outside your door, original brownstone charm pairs effortlessly with the enduring appeal of Park Slope’s landmarked streetscape. Residents will enjoy immediate access to the neighborhood's finest boutique shopping, cafes, and culinary institutions, including Vato, Il Leone, Sotto Voce, Bar Louise, Pino's Famous Pizzeria, Sushi Katsuei, and Variety Coffee Rosters. You are positioned just two blocks from the rolling lawns of Prospect Park and moments away from JJ Byrne Park and its vibrant weekend farmers market.

Ideally situated for an effortless commute, the home is exceptionally close to the F train at 7th Ave, the Q and B at Flatbush, the 2/3 at Grand Army Plaza, and the N/R at 9th Street and Union Street stations. Don't miss this rare opportunity to acquire a pristine piece of historic New York City real estate on a benchmark Park Slope block. Call, email, or text to schedule your private showing.

Based on house sales in Park Slope with the required listing and closing data. Sample sizes vary by metric.

These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure.

Sales data through September 2026.

Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.

Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.

Figures are the New York City Department of Finance assessment roll for tax lot 3010780072. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
