A full New York City apartment renovation — touching finishes, millwork, flooring, kitchen, bathrooms, and more — is one of the most complex projects a homeowner undertakes. The difference between a successful renovation and a nightmare is almost always planning. Here's a complete checklist.
Phase 1: Planning (2 to 4 Months Before Construction)
- Define full scope of work in writing — every room, every finish, every system
- Read your co-op or condo alteration agreement in full
- Hire an architect or designer if scope requires it (structural changes, permit-required work)
- Get minimum three contractor bids for the full scope
- Identify long-lead items: custom millwork (6 to 12 weeks), specialty tile (4 to 10 weeks), appliances (4 to 16 weeks)
- Create realistic budget with 15 to 20 percent contingency
Phase 2: Approvals (4 to 12 Weeks)
- Submit co-op alteration agreement package to building
- Gather all required contractor documentation (COI, workers comp, licenses)
- Obtain any required permits (DOB, plumbing, electrical)
- Notify downstairs neighbor if wet area work is involved
- Schedule elevator time with building
Phase 3: Demo and Rough Work (2 to 4 Weeks)
- Demolition of existing finishes
- Plumbing rough-in (if layout changes)
- Electrical rough-in and panel upgrade if required
- Framing for any new walls
- Waterproofing membrane in wet areas
- Building inspection sign-offs before closing walls
Phase 4: Finishes (4 to 12 Weeks)
- Drywall or plaster work
- Tile installation
- Decorative wall finishes (venetian plaster, roman clay, etc.)
- Millwork fabrication and installation
- Flooring installation or refinishing
- Painting (walls, trim, ceiling)
- Fixture and appliance installation
- Hardware and trim details
Phase 5: Completion
- Final punch list walkthrough with general contractor
- Final permit sign-offs and certificate of occupancy if required
- Touch-up items resolved before final payment
- Building restoration documentation (elevator, common areas)
- Submit as-built documentation to co-op board
