Brownstone, townhouse, or rowhouse? In Brooklyn, these words often get used as if they mean the same thing. If you are buying or selling, the differences affect your budget, renovation plans, approvals, and resale. In this guide, you will learn what each term means, where you will find them in Kings County, what rules apply, and what to inspect before you commit. Let’s dive in.
What each term really means
Brownstone explained
A brownstone is a 19th‑century building faced in brown sandstone, usually with a stoop and parlor‑floor layout. You will see Italianate, Neo‑Grec, Romanesque Revival, and Renaissance Revival details depending on the block and era. People often use “brownstone” to describe any historic townhouse, but the true term refers to the stone façade, which weathers over time and needs specific repair techniques.
Townhouse explained
A townhouse refers to a vertically oriented home that one owner holds in fee or as a condo unit. In Brooklyn, the term can describe a single‑family or 2–4 family building, historic or new. Many buyers use “townhouse” to mean full‑building living with private entrances and multiple floors.
Rowhouse explained
A rowhouse is one home in a continuous row of similar units that share side walls. Materials vary, often brick or painted brick, and façades tend to be simpler than high‑style brownstones. Many Brooklyn rowhouses date to the late 19th and early 20th century and share similar vertical floor plans.
Where you will find them in Brooklyn
You will see the highest concentration of 19th‑century brownstones and historic townhouses in Brooklyn Heights, Cobble Hill, Carroll Gardens, Park Slope, Boerum Hill, Fort Greene, Clinton Hill, Prospect Heights, and Bedford‑Stuyvesant. Many blocks within these neighborhoods fall inside designated historic districts managed by the NYC Landmarks Preservation Commission.
Brick rowhouses and broader townhouse styles appear across Bay Ridge and Sunset Park, with additional pockets in Prospect Lefferts Gardens, Ditmas Park, Kensington, and parts of Williamsburg and Greenpoint. Neighborhood character and pricing vary widely by block, condition, and landmark status.
Rules that shape what you can do
Landmark districts and exterior work
If the property is inside a landmark district, exterior changes usually need LPC approval before you can pull permits. That includes façade and stoop work, windows, cornices, and many roofline changes. Expect longer timelines and strict guidelines. You can review district maps and permit guidance on the LPC site.
DOB permits and past work
Structural changes, enlargements, and use conversions require permits and inspections through the NYC Department of Buildings. Older buildings often have unpermitted alterations or illegal apartments, which can affect financing and closings. Confirm records and resolve issues through the DOB’s permit and violations resources.
Zoning and expansion limits
R‑zoning districts set height, floor area, rear yard, and setback rules that control rooftop additions, rear extensions, and cellar changes. Zoning can change block by block, so verify feasibility early with an architect and the NYC Department of City Planning’s zoning maps.
Taxes and property classes
In NYC, 1–3 family houses are usually Class 1, while condos, co‑ops, and many multi‑family buildings fall under Class 2. Your tax class affects assessments and your annual bill, and it may change with use conversions. Review definitions and tools at the NYC Department of Finance.
Flood zones and resiliency
Parts of Brooklyn, including Red Hook, Coney Island, Gerritsen Beach, and areas of Bay Ridge and Greenpoint, sit in FEMA flood zones. Lenders may require flood insurance, and post‑Sandy resiliency rules affect utilities and finished lower levels. Check risk using the FEMA flood map portal and confirm renovation requirements with your architect.
Costs, financing, and ownership
- Ownership types: You will see fee simple townhouses, townhouse‑style condos, and less commonly, co‑ops in converted houses. Two to four family buildings can be great for live‑plus‑rental setups, but confirm legal unit status.
- Financing: 1–4 family homes typically qualify for standard residential financing. Co‑ops and condos have different underwriting standards. Renovation loans are possible, but landmark and zoning rules will shape the scope, cost, and timeline.
- Insurance: Expect different coverage for single‑family, owner‑occupied multi‑family, and flood‑zone properties. Historic buildings can carry higher premiums due to materials and systems.
- Carrying costs: Brownstone façades, stoops, roofs, and mechanicals require periodic work. It is smart to set an annual reserve for masonry and water‑management projects.
Inspections and maintenance to prioritize
Older Brooklyn houses share similar age‑related issues. Prioritize the following during due diligence:
- Masonry and façades: Brownstone is porous and weathers. Budget for patching, stone replacement, repointing, and potential lintel or stoop repairs. For context on methods and costs, explore practical overviews like brownstone repair basics.
- Roof and cornice: Look for water intrusion, aging membranes, and wood or metal cornice deterioration. Rooftop decks or additions require structural review and approvals.
- Foundation and water: Check for moisture, efflorescence, sump pumps, backflow preventers, and sewer line condition.
- Mechanical systems: Assess boilers, radiators, electrical panels, wiring type, and plumbing supply lines. Knob‑and‑tube wiring and galvanized pipes often need replacement.
- Environmental: Expect the possibility of lead paint and asbestos in pre‑1978 buildings. Plan for safe testing and remediation during renovations.
Quick buyer checklist
- Confirm landmark status and review LPC guidelines.
- Pull the DOB folder for permits, violations, and open jobs through the Buildings portal.
- Verify zoning and addition potential via NYC Planning.
- Check tax class and current assessment at NYC Finance.
- Look up flood risk on the FEMA flood map.
- Hire the right team: architect or engineer, licensed plumber and electrician, and a mason with historic façade experience.
Seller moves that pay off
- Document work: Keep permits, approvals, and contractor receipts organized. Buyers and lenders will ask.
- Resolve violations: Clearing DOB issues early can protect your timeline and price.
- Prepare the exterior: Address obvious façade and stoop maintenance to support the inspection and first impressions.
- Set expectations: If you are in a landmark district, provide buyers with any LPC approval history to show what is feasible.
Resale and value drivers to watch
- Block and district: Landmark districts with cohesive streetscapes often command stronger pricing. Rules can add holding time for permits but protect long‑term character.
- Width, depth, and layout: Wider lots and clean parlor‑floor layouts tend to show better and support higher values.
- Condition and legality: Well‑documented systems upgrades and legal unit status reduce risk and support pricing.
- Expansion potential: Within zoning and LPC limits, a lawful rear or rooftop addition can add real value.
Brownstone vs townhouse vs rowhouse: how to choose
- Start with lifestyle: Decide if you want single‑family living or a 2–4 family with rental income.
- Check approvals and appetite: If you plan to add a deck or expand, confirm landmark and zoning feasibility first.
- Budget for the envelope: Set aside funds for façade, roof, and water‑management work, especially on true brownstones.
- Compare blocks, not labels: A modest rowhouse on a great block can outperform a grand house in a weaker location. Look at recent local comps and condition.
Neighborhood snapshots
- Brooklyn Heights, Park Slope, Cobble Hill, Carroll Gardens, Fort Greene, Clinton Hill, Prospect Heights: Rich with 19th‑century townhouses and brownstones, many in LPC districts. Expect premium pricing and careful preservation.
- Bed‑Stuy: Broad mix of brownstones and multi‑unit townhouses with active renovation and restoration.
- Sunset Park, Bay Ridge: Continuous rows of brick townhouses and rowhouses, often with simpler façades and strong neighborhood cohesion.
