Our Co-op and Condo Renovation Services
Alteration Agreement Management
Every co-op and condo renovation begins with the board approval process. We prepare complete alteration agreement packages including architectural plans, contractor insurance certificates (general liability and workers’ compensation), work schedules, noise mitigation protocols, and scope of work descriptions. Our familiarity with board requirements across hundreds of NYC buildings means we submit packages that get approved faster — often on the first submission without revision requests.
Kitchen Renovation in Managed Buildings
Kitchen remodeling in co-ops and condos requires coordination with building plumbing stacks, adherence to appliance specifications (many buildings restrict gas ranges), and compliance with noise restrictions during construction. We redesign layouts, install custom cabinetry, and upgrade countertops while maintaining building management approval at every stage.
Bathroom Renovation with Stack Coordination
Bathroom renovations in managed buildings demand coordination with shared plumbing stacks for water shutdowns, proper waterproofing to protect neighboring units, and building-approved materials. We install walk-in showers, modern vanities, and heated floors while scheduling plumbing tie-ins around building-mandated access windows.
Electrical Panel Upgrades
Many older co-ops and condos have insufficient electrical capacity for modern appliances and technology. We install 200-amp panel upgrades, dedicated circuits, and GFCI protection while coordinating with building electricians for service entrance modifications and meter work.
Flooring with Sound Attenuation
Most co-op and condo buildings require specific sound transmission ratings (STC/IIC) for new flooring installations. We install hardwood, engineered wood, and luxury vinyl plank with proper sound-dampening underlayment that meets or exceeds building requirements — and we provide test reports for board review when required.
Full Gut Renovation
Complete interior demolition and reconstruction in managed buildings requires careful planning, staging, and communication with building management. We handle debris removal scheduling, elevator padding, common area protection, and construction hour compliance while delivering the same quality results as any gut renovation project.

How Much Does a Co-op or Condo Renovation Cost in NYC?
Co-op and condo renovation costs in New York City include standard construction expenses plus building-specific administrative costs. Here are general ranges based on our project history:
Cosmetic Update (paint, fixtures, hardware): $15,000–$30,000
Mid-Range Remodel (kitchen, bathroom, flooring): $50,000–$120,000
Full Gut Renovation (layout changes, all new systems, custom finishes): $150–$400+ per square foot
Co-op and condo-specific cost factors include:
- Alteration agreement filing fees charged by the building (typically $500–$5,000+)
- Building-required insurance minimums (often $1M–$2M general liability)
- Architect or engineer review fees required by some buildings
- Building-mandated work hours that extend project timelines
- Elevator reservation fees and common area protection deposits
- Required post-renovation inspections by building engineers
We provide itemized estimates that separate construction costs from building-related administrative expenses so you can budget accurately.
