Manhattan Apartment Renovation Cost Estimator

Real Manhattan renovation pricing, in plain English. A refresh runs $100–$320 per square foot. A full renovation runs $350–$750 per square foot. A gut runs $600–$1,200 per square foot at trophy-building level. Below, model your specific apartment — including the condition multipliers, soft costs, co-op overhead, and the contingency NYC renovations always need.

Top-end ranges calibrated against active TRH NYC client pricing on Park Avenue, Fifth Avenue, Central Park South, and Central Park West trophy buildings. Broad-market lower ends sourced from early-2026 Manhattan contractor guides (Corniel 3/2026, Chapter 1/2026). Costs up ~6–9% vs. 2024–2025 driven by labor, tariffs, and DOB code changes.

Apartment size
square feet
Renovation scope
Kitchen and baths fully replaced, new floors, all finishes refreshed. Layout mostly stays the same.
What’s typically included
  • Complete kitchen replacement (cabinets, counters, appliances)
  • Bathrooms gutted to studs and rebuilt
  • New hardwood or stone flooring throughout
  • Smooth-wall plaster refinishing
  • Updated lighting design and electrical panel
  • Plumbing replacement where walls are opened
  • Custom millwork (basic level)
Building type
Co-ops add alteration-agreement fees, board review time, and stricter insurance / bond requirements.
Current condition
Estate / prewar conditions add 15–25% for asbestos abatement, system upgrades, and prewar surprises.
Add central HVAC?
Moving walls / changing layout?
What goes into the number
  • Hard construction — demo, framing, plumbing, electrical, kitchen, baths, floors, finishes.
  • Soft costs — architect, DOB filings, engineering, permits, interior design.
  • Co-op overhead — alteration agreement, insurance bond, security deposit, building fees.
  • Contingency — 15% reserve for prewar surprises (aging plumbing, subfloor leveling, asbestos).
What inflates the number
  • Prewar buildings — old systems, period restoration requirements, frequent asbestos abatement.
  • Layout changes — moving walls, especially load-bearing, adds engineering + filings.
  • Strict co-op boards — limited work hours, monthly review cycles, expanded insurance requirements.
  • Custom millwork + smart-home systems — can add $50K–$200K+ at the gut level.
What the timeline really means
  • Design + drawings — architect develops the plan set the contractor will price and the board will review.
  • Board package + approval — most co-ops require a full alteration application before any work starts.
  • Construction — only happens after the green light. Co-op work hours (typically 9 AM – 4 PM weekdays only) often double the calendar time.

Renovating a specific apartment?

Every building, every contractor, every board agreement is different. Before you commit to a contract, the right call is a 30-minute conversation about your specific situation — what the board allows, which contractors actually deliver in your building, and what the all-in number really looks like.
