Co-op & Condo Renovations in NYC, Built Around Your Building's Rules
Renovation planning and building coordination for NYC co-op and condo owners.
The Alteration Agreement, Handled
Renovating in a managed building is two projects at once: the work inside your apartment, and the paperwork, approvals and logistics that satisfy your board and managing agent. Citi Skyline Interiors has handled both for New York City co-op and condo owners since 2010. We take care of the alteration agreement, certificates of insurance and building coordination so you can focus on the design, and so your building sees a contractor that follows its rules from day one.
One co-op client put it simply: "If you have a co-op, you know management/boards can be very strict and demanding. Henry ensured every rule and guideline was followed to their satisfaction." (Alexandra F.)

Most co-ops and condos require an alteration agreement before any work begins, and boards review it closely. We prepare the contractor side of the package: scope of work, company information, license and insurance documents, schedule and any other items your building's alteration package asks for. Where the building or the scope calls for drawings or permits, we coordinate them along with your architect or engineer if you have one.
We know an incomplete package is the most common cause of delay, so we work through the building's checklist item by item and respond quickly when the managing agent or the board's architect comes back with questions.
Certificates of Insurance, Including Our Subcontractors
Buildings want proof that everyone working on site is insured, naming the parties the building specifies. Citi Skyline is fully licensed and insured, and we issue certificates of insurance (COIs) in the form your managing agent requires. We also collect and submit COIs for our subcontractors, such as plumbers and electricians, so there are no gaps and no last-minute holds at the service entrance.
Board Approval and Working Hours
Nothing starts until the board or managing agent gives the green light. Once it does, we mobilize right away. We schedule the job around your building's permitted working hours, noise rules, elevator reservations and delivery windows, and we plan the sequence of work so loud demolition and deliveries happen when the building allows them.
Protecting Common Areas and Your Neighbors
Your neighbors share the lobby, hallways and elevators with our crew. We protect the route from the service entrance to your door, keep the work area clean and organized, and remove debris responsibly according to building rules. The goal is that the only sign of the renovation is a better apartment at the end.
Clear Communication With the Managing Agent
Property managers and superintendents get one point of contact at Citi Skyline. We share the schedule in advance, give notice before water or electrical shutoffs, and keep the managing agent updated when the building has questions or concerns. If the building needs to pause or slow the work, we adjust and keep everyone informed.
