1. Quick Snapshot: Dollars, Days & Decisions
- Median U.S. gut-renovation cost (2023): $100 psf (U.S. Census ACS).1
- Manhattan bump: +35 % to +60 % thanks to union labor, board rules, and DOB filing fees.
- Permit trigger: NYC Department of Buildings requires Alteration Type 2 permits for layout changes, plumbing, or electrical.2
- Material inflation: Finish materials rose 2.8 % YOY (BLS PPI).3
- Typical 2025 range: $175 – $250 psf (cosmetic) • $260 – $425 psf (wet-over-dry or layout move) • $450 psf + (luxury, landmarked)
- Timeline: 8–12 weeks (cosmetic) • 20–28 weeks (full gut) • +4–6 weeks if landmark approvals needed
Rule of thumb: For a 900 sq ft one-bedroom, a mid-grade Manhattan apartment renovation falls near $235 000.
2. Why Do Manhattan Apartment Renovation Costs Climb?
2.1 Labor & permits
Union carpenters, plumbers, and electricians average $110 – $145 hr. DOB Alteration 2 filing plus expedite often tops $6 000 before reviews.
2.2 Co-op / Condo board rules
Boards demand $1 M–$3 M liability insurance riders, elevator pads, and “summer-only” work calendars. Courier fees, submittals, and move-in/out deposits add $7 000–$12 000.
2.3 Freight elevators & staging
Materials travel up freight lifts that shut at 4 p.m. Each lost hour is a billed hour. Exterior hoists on landmarked facades need Landmarks Preservation Commission (LPC) sign-off.
2.4 Material inflation
BLS PPI shows hardwood flooring up 3.1 %, custom cabinetry 2.4 %, and plumbing fixtures 2.9 % YOY.3

4. Graph: Average Daily GHI in Different Midtown Locations
| Neighborhood | Average Daily GHI (kWh/m²) |
|---|---|
| Upper West Side | 4.16 |
| Midtown East | 4.14 |
| Financial District | 4.12 |
| Harlem | 4.18 |
| Battery Park City | 4.11 |
Why share sunlight data? Higher GHI means bigger cooling loads. Low-e windows and reflective shades can trim AC usage by 8 %–15 %.
5. Five Ways to Save (Without Cutting Corners)
- Batch DOB filings. Kitchen + bath under one Alteration 2 saves a second $2 800 filing fee.
- Refinish, don’t replace, parquet. Sand-and-seal costs $7 psf vs $16 psf for new oak.
- Use factory-primed doors. Saves two paint coats, about $450 on a one-bedroom.
- Specify stock cabinets. Semi-custom boxes drop millwork line item by 30 %.
- Plan elevator runs. Time deliveries for freight-only windows (7–9 a.m.) to avoid $300 overtime fees.

10. FAQ
How long does DOB plan approval take?
Standard review averages 15 business days; Professional Certification (“Pro-Cert”) can cut that to 1–2 days but shifts liability to your PE/RA.
Can I live in the apartment during renovation?
Only for light cosmetic work. Full gut jobs require vacating per NYC Housing Maintenance Code once kitchens/baths are offline.
Do I need soundproofing?
Most co-ops demand an IIC rating ≥ 60. 3-layer underlayment + ¾ in oak achieves it.
What finishes increase resale the most?
Quartz counters, wide-plank oak, and walk-in showers ranked highest in the 2024 StreetEasy buyer survey.
Is combining two units tax-efficient?
Yes—mergers often get a single lower assessed value than two separate units, trimming annual taxes.
