Walk Fort Greene on a weekday morning and you will see what makes renovation here different: tall brownstones with original stoops, mature street trees, and the occasional scaffolding pole where someone is repairing a cornice. This is a neighborhood where people live in their houses, sometimes in all of them, sometimes with a tenant on the garden floor, and almost always with a long list of things they would change.
This guide is written for owners in 11205 and 11217 who are weighing a renovation. It covers the rules that apply in a historic district, the questions that matter for houses with more than one household, the costs of the most common jobs and what order everything should happen in.
The word "brownstone" covers a lot. Before you price anything, work out which kind of house you actually own.
The owner-occupied single family. One household, four or five floors, a garden level with a kitchen, a parlor floor with plaster ceilings, and bedrooms above. Projects tend to be kitchen and bath rebuilds plus floor restoration, with occasional rear extensions.
The owner-plus-rental. An owner lives in the upper floors and rents out the garden floor or the top floor, or both. Renovation here has to respect a tenant's lease, safety and access, and often a legal-use history that may not match what the house is today.
The converted multi-unit or condo-style house. Some houses were divided into apartments long ago, others have been converted into condominiums. Alteration rules, shared systems and neighbors' schedules matter more than floor plans.
Many of the questions below apply to all three, but the second type creates the most surprises, which is why it gets its own section.
Before you design a layout, check what your house is legally allowed to be. The certificate of occupancy describes the approved use and number of dwelling units. Many older brownstones have been informally combined or divided over the decades, and the paperwork does not always match what you see.
Why this matters for renovation:
A registered architect or engineer reviews these facts before filing. Our permit checklist gives a first-pass idea of which work is filed and which is not, and the Department of Buildings explains the basics at its permit guidance page. For large rebuilds, the process is similar to the one described in our guide to gut renovation contractors in Brooklyn.
If someone else lives in your house, the renovation is partly their project too. A good plan treats them as a stakeholder, not an obstacle.
Tell tenants what will happen, in writing, before work starts: which days are noisy, when water or power will be off, and how long the work will last. Reasonable notice avoids conflict and reduces complaints to the city.
Plaster dust and demolition debris travel through stairwells and radiators. Walls of plastic sheeting, zipper doors, negative air machines where appropriate, and HEPA vacuums keep shared hallways livable. Shared stair treads and banisters should be protected from every trip.
If a tenant's kitchen is on the same stack as your bathroom, a re-pipe cuts their water. Schedule shutoffs in short windows and give tenants a way to flush a toilet or wash dishes in the interim.
Keep stairs and exits clear at all times. Never block a fire exit with materials, even briefly.
Tenants in New York have strong protections, including rules against construction used to harass. The Department of Housing Preservation and Development publishes tenant and owner information at its HPD site. Ask your architect and an attorney what applies to your building before work starts.
Fort Greene is a designated historic district, so the Landmarks Preservation Commission regulates changes visible from the public street. The goal is to preserve the character of rows of brownstone and brick houses, along with their stoops, ironwork and cornices.
| Project | LPC review likely? |
|---|---|
| Interior renovation, no exterior change | Generally no |
| Front window or door replacement | Yes |
| Stoop repair and railing replacement | Yes |
| Facade masonry cleaning or repointing | Yes |
| Rear addition visible from the street | Yes |
| New rooftop mechanical or bulkhead | Often yes |
| Painting previously painted trim | Often no, but verify |
Three LPC permit types apply: a Certificate of No Effect, a Permit for Minor Work and a Certificate of Appropriateness. The LPC permit applications page explains them. Routine work typically moves faster; major changes can require a public hearing and more time. Allow roughly 15 to 20 percent more time and budget on landmarked buildings.
Remember that LPC approval and Department of Buildings approval are separate. Neither replaces the other.
In a house like this, the cheapest bid often turns out to be the most expensive one.
Start with the legal side. Residential remodeling in NYC requires a Home Improvement Contractor license through the Department of Consumer and Worker Protection. Without one, you have weak recourse if work stops, and many insurers and lenders will not look favorably on the paper trail.
Then the technical side. A brownstone's floor structure is rarely level, and a tile or hardwood installer who does not account for that creates cracking tile and squeaking floors. Plaster over wood lath can crumble if the wrong tool is used. Water behind a shower wall without a proper membrane rots joists, and the damage appears long after the handyman has left. In an occupied house, failing to contain dust is not just rude; it can make people sick.
At N.Y. Renovation Services, one in-house team handles design, permits, demolition, rough-in, tile, flooring and paint. We are licensed and insured, we prepare the drawings and paperwork, and we sequence trades so that one does not undo the work of another. If you rent part of your house, we will build the schedule around tenant needs and put utility shutoffs in writing.
You also get transparency. Our quotes are itemized, our contracts are written and no hidden fees appear later. Allowances are labeled as allowances.
The figures below are typical planning ranges for the New York metro area as of October 2026. They are not quotes. Scope, access, hazmat, finishes and landmark review change the final price, and a written itemized quote governs.
| Project | Typical 2026 planning range |
|---|---|
| Cosmetic refresh | $100–$250 per sq ft |
| Mid-level renovation with kitchen and bath | $200–$400 per sq ft |
| Full gut renovation | $250–$500+ per sq ft |
| Structural or high-end | $500–$1,000 per sq ft |
| Full bathroom | $30,000–$60,000+ |
| Kitchen | $25,000–$85,000+ |
| Interior demolition and haul-away | $8–$30 per sq ft |
| Design, engineering and filing | About 15–25% on top |

Finish work is where a brownstone's character is either protected or erased.
Original oak or pine floors can often be refinished, which typically runs about $4 to $10 per square foot. If boards are damaged or have been patched with mismatched species, replacement at roughly $12 to $28 per square foot installed for engineered or solid hardwood may make sense. Ask whether the existing floor was sanded many times already, because thin wear layers cannot take another full sanding. Dust containment matters in an occupied house.
Standard porcelain or ceramic floor tile typically plans at $20 to $45 per square foot installed; bathroom walls and showers at $30 to $80; backsplashes at $30 to $90. A waterproofing membrane adds roughly $3 to $10 per square foot, and removal of old tile runs $4 to $12. Natural stone, large-format tile and mosaics cost more. On an uneven brownstone floor, leveling and an underlayment or decoupling membrane protect the tile from cracks.
Repair cracks, re-secure loose plaster and skim where needed. Replacing plaster with drywall changes the sound and the feel of a room; some owners do it in bathrooms and closets but retain plaster in parlors.
Painting an older house requires lead-safe practices if paint is from before 1978. The EPA explains the Renovation, Repair and Painting rule in plain language. Interior painting is the last step, so it happens after dusty trades are done.
The following illustrates how a typical two-floor renovation might sequence. Actual dates depend on scope, approvals and the house.
| Phase | Typical duration | Notes |
|---|---|---|
| Survey, testing and design | 3–6 weeks | Asbestos and lead testing first |
| LPC and DOB filings | Weeks to months | Parallel when possible |
| Demolition | 1–2 weeks | Containment critical in occupied houses |
| Rough plumbing and electrical | 2–4 weeks | Inspections |
| Framing, insulation, plaster | 2–3 weeks | Match existing profiles |
| Tile and waterproofing | 1–2 weeks per bath | Includes membrane cure |
| Kitchen cabinets and counters | 1–3 weeks | Countertop templating |
| Floors | 3–7 days plus finish cure | After dusty work is done |
| Paint and punch list | 1–2 weeks | Final touch-ups |
A bathroom typically takes 3 to 6 weeks, a kitchen 6 to 12 weeks and a full gut several months, including approvals. Weekday construction hours generally run about 7 AM to 6 PM under NYC noise rules, and you should respect any additional limits your block or tenants expect.
The process at N.Y. Renovation Services in Fort Greene follows a simple pattern: understand the house, price it honestly, file it correctly, build it in the right order.
During the walk-through, we look at structure, systems and signs of earlier work. We ask about legal use, tenants and your plans for the house in five or ten years, because the right renovation depends on the answers. You receive a free estimate, with an itemized quote that separates demolition, rough-in, tile, flooring, millwork, paint and cleanup.
The N.Y. Renovation Services design-and-build team prepares plans and works with the registered architect or engineer who files with the Department of Buildings, and we gather the materials the Landmarks Preservation Commission requires. If you want us to manage the permitting and paperwork, we do.
On site, we protect stairs, banisters and shared areas, contain dust, schedule shutoffs in writing and keep a clean job. Hazmat testing comes before demolition, waterproofing is tested before tile, and paint goes on last. Payments are tied to progress, not to a calendar.
We also donate 5% of the total project cost to a nonprofit chosen by you. It is part of the contract, not a marketing add-on.
Century-old houses can hold hazardous materials. They are manageable with the right process and unmanageable without one.
Lead paint. If your house was built before 1978, paint may contain lead. Under the EPA's rule, firms paid to disturb paint must be certified and use lead-safe practices. New York City has additional lead requirements for older buildings, particularly those built before 1960. If a child under six lives in or visits the house, take this especially seriously.
Asbestos. Older floor tile, mastic, pipe insulation and some plaster or joint compound can contain asbestos. A survey is standard before demolition in buildings of a certain age (pre-1987 commonly triggers one), and certified abatement is required if asbestos is present. We never promise a house is asbestos-free before it has been tested.
Silica. Cutting tile, stone or masonry produces respirable crystalline silica dust. Wet cutting, vacuum extraction and respirators are the standard controls.
General dust. In an occupied house, containment and HEPA filtration protect not only workers but also tenants, pets and children.
We work across Brooklyn and the rest of New York City. This guide focuses on Fort Greene, ZIP codes 11205 and 11217.
Fort Greene's mix of brownstones and rental floors makes it different from the wood-frame Victorians of Flatbush, the brick multifamily blocks of Bushwick and the attached homes of Bensonhurst. Waterfront edges of Brooklyn, including Sheepshead Bay, have flood-zone rules that rarely arise inland. For borough-level service details, see Brooklyn renovation services.
Before you sign any contract, run through the basics. Verify the Home Improvement Contractor license, ask for a current certificate of insurance and request an itemized written quote. Compare more than one bid on the same scope. Our contractor hiring checklist lists every question worth asking.
Then take the simple next step with N.Y. Renovation Services. Send us your address, the floors involved, your goals and a few photographs. We will schedule a walk-through, ask about legal use and tenants, and return an itemized quote with approvals mapped out. The estimate is free, and you can ask us to handle the filings from the start.
Prices and rules in this guide are current as of October 2026. Confirm specifics with the Department of Buildings, the Landmarks Preservation Commission and your insurer before work begins.
