What We Do

Our Co-op and Condo Renovation Services

Each scope below is delivered under one general contract, with board submissions, licensed trades, filed permits, and schedules built around your building's rules.

Alteration Agreement Management

Every co-op and condo renovation begins with the board approval process. We prepare complete alteration agreement packages so your submission clears review without repeated revision requests.

  • Architectural plans coordinated with your architect or ours
  • Contractor insurance certificates (general liability and workers' comp)
  • Detailed scope of work descriptions
  • Construction schedules with start and end dates
  • Noise mitigation protocols
  • Common area protection specifications

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.

More on Electrical Services

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.

More on Flooring Installation

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.

Cost

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+ / sq ft

Co-op and condo-specific cost factors

  • 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 — including line items for flooring underlayment and sound testing when your board requires it.

Board Approvals

Navigating the Co-op and Condo Board Approval Process

Board review is where most NYC renovations stall. We prepare submissions the way managing agents expect them, then run construction inside the rules the approval sets.

What's Required for Board Approval

Most NYC co-op and condo boards require: a detailed scope of work, architectural plans (for structural or layout changes), contractor insurance certificates, a construction schedule with start and end dates, noise mitigation plans, and common area protection specifications. Some buildings also require a refundable security deposit and neighbor notification letters.

How We Streamline Approvals

Our team maintains pre-formatted submission packages that we customize for each building's requirements. We've worked in hundreds of managed buildings across all five boroughs, so we often know a building's specific requirements before the first board meeting. When revisions are requested, we respond within 48 hours to keep your timeline on track.

Working Within Building Rules During Construction

Once approved, we comply with all building-mandated protocols: construction hours (typically 8am–5pm weekdays), elevator reservations for material delivery, debris removal scheduling, common area floor and wall protection, and noise mitigation during demolition phases. Our project managers coordinate directly with building supers and management companies.

Common area protection and elevator reservations are set up before the first delivery — a condition of nearly every alteration agreement we submit.
