Manhattan renovation projects come with a layer most other boroughs don't: co-op and condo board approval, freight elevator scheduling, and buildings where the walls behind the plaster don't match any standard blueprint. Illyrian Group Corp runs general contracting and gut renovation projects, the home renovation work Manhattan buildings actually need, with that reality built into the plan, not treated as a surprise mid-project. It's why board-managed buildings tend to look for a construction contractor in NYC who already knows the approval process, rather than one learning it on your job.
Board approval is usually the item that determines your actual timeline more than the construction itself. A straightforward cosmetic renovation with no layout change might not need board sign-off at all, while a full gut with plumbing relocation typically requires an alteration agreement, an insurance rider naming the building, and a contractor package the board reviews before you can pull a permit. We prepare that package as part of the project, not as a separate scramble once demo is supposed to start.
A typical Manhattan client comes to us after buying a resale co-op that hasn't been touched since the 1980s, or after living in a rental long enough to decide it's time to fully renovate an owned unit. Either way, the first walkthrough is where we separate what the board will actually approve from what you'd ideally want, so the proposal you sign reflects a project that can get through review, not one that stalls at the submission stage.

Manhattan Home Renovation Tiers: Standard, Mid-Range, and High-End
What we spec depends on whether you're refreshing a rental unit, renovating a home you'll live in for years, or restoring a prewar apartment to a standard that matches the building.
Standard
Contractor-grade finishes: laminate or stock tile flooring, builder-grade cabinetry, laminate or basic quartz counters, and code-minimum lighting. Common for a unit being prepared to rent or list.
Mid-Range
Semi-custom cabinetry, engineered hardwood or porcelain tile, quartz counters, and upgraded fixtures. Where most owner-occupied Manhattan condo and co-op renovations land.
High-End
Full custom cabinetry, natural stone counters, wide-plank hardwood, and millwork that matches original prewar detail. Common in Central Park West and Fifth Avenue co-ops undergoing a full restoration.

What Can Complicate a Manhattan Home Renovation
- Board denial risk. Some boards reject scope like moving a kitchen gas line or altering a shared wall outright, which we flag during the walkthrough, not after a proposal is drafted.
- Landmarks Preservation Commission review. Buildings in a historic district, common on the Upper West Side and Upper East Side, need added design review for street-visible or protected interior changes.
- Freight elevator scheduling. Buildings with one service elevator often limit construction deliveries and debris removal to specific hours, which affects how fast material moves.
- Original plaster and cast iron plumbing. Prewar buildings frequently hide plumbing stacks and wall conditions that don't match a standard new-construction estimate.
- Pre-1978 lead paint testing. Older Manhattan buildings may require lead testing and EPA Lead-Safe work practices before demo begins.
- Insurance rider requirements. Most boards require a certificate of insurance naming the building before a contractor can start, which we handle as part of the board package.

A 1-Year Workmanship Warranty on Every Manhattan Project

Manufacturer warranties on fixtures, cabinetry, and appliances pass through to you separately, and we keep documentation on file in case your board or managing agent asks for it.
How Much Does a Gut Renovation Cost in Manhattan?
A full Manhattan gut renovation typically runs $200-$350 per square foot, or roughly $80,000-$180,000 for a studio or one-bedroom and $150,000-$400,000+ for a multi-bedroom unit. Prewar co-ops with board approval and older plumbing risers tend to land at the higher end. We confirm your exact number with a free written, itemized estimate after seeing the apartment.
Serving Manhattan Renovation Projects
Illyrian Group Corp's office is in East Brunswick, NJ, roughly an hour from Manhattan depending on traffic and crossing. We schedule crews and material deliveries around Manhattan building access windows and bridge/tunnel timing so your project stays on schedule.
We've worked in buildings from the Upper West Side (10024) and Upper East Side (10128) to Tribeca (10013) and Chelsea (10011), in both prewar co-ops near Central Park with plaster walls and cast iron plumbing, and newer condo towers with stricter building management protocols. Buildings inside a Landmarks Preservation Commission historic district, common across the Upper West Side and Upper East Side, get an added review step we plan for up front, not mid-project.
Questions to Ask Before Hiring a Manhattan General Contractor
- Are you experienced with my building's board approval process? A contractor unfamiliar with Manhattan board packages can add weeks to your timeline with a rejected first submission.
- Who pulls the DOB permit, and under whose license? Confirm the permit is filed correctly and tied to a licensed filer, not handled informally.
- What's in the written estimate versus billed as a change order later? Get this distinction in writing before you sign anything.
- How do you handle unexpected conditions behind prewar walls? Ask how change orders are priced if old plumbing or wiring needs replacing mid-project.
- What's covered under warranty, and for how long? Confirm the workmanship warranty term and how manufacturer warranties on fixtures and appliances are handled separately.
Frequently Asked Questions - Manhattan General Contracting
Do you work with Manhattan co-op and condo boards?
Yes. Manhattan co-op and condo renovations typically require an alteration agreement, proof of insurance, and a contractor package submitted to the board before work starts. We've prepared these submissions for buildings across Manhattan, including reviewing your proprietary lease or offering plan for building-specific restrictions, and we factor board review time into your project schedule from day one.
Can you renovate a prewar apartment with original plaster walls?
Yes. Many Manhattan prewar buildings have plaster walls and ceilings, cast iron plumbing stacks, and layouts that don't match modern renovation plans. We assess the existing conditions during the walkthrough, sometimes opening a small test section of wall first, and build a scope that accounts for what's actually behind the walls, not just what a standard new-construction estimate would assume.
How do you handle renovation work in an occupied Manhattan building?
We coordinate with building management on elevator reservations, work hours, and dust and noise containment, which most Manhattan buildings require in writing before a permit is issued. Debris removal is scheduled around the building's freight elevator hours, and we keep neighboring units informed of any particularly loud phases like demo.
Does my Manhattan renovation need Landmarks Preservation Commission approval?
Only if your building sits in a designated historic district, like parts of the Upper West Side or Upper East Side, and the work is visible from the street or changes a protected interior element such as a lobby or facade. We flag this during the walkthrough and factor LPC review time into your schedule before filing DOB permits, so it doesn't surprise you mid-project.
