Multi Construction Co. has been renovating Manhattan apartments, townhouses, and commercial spaces for over 37 years. We understand how to navigate building management rules, prepare co-op board submissions, coordinate with the Landmarks Preservation Commission, and execute projects that meet New York City’s requirements from permit filing to final walkthrough.
Manhattan’s housing stock spans over a century of building types — pre-war co-ops constructed between 1910 and 1940, mid-century residential towers, cast iron loft buildings in SoHo and Tribeca, converted industrial spaces in Chelsea and Hell’s Kitchen, and modern high-rise condominiums throughout Midtown and Lower Manhattan. Each building type carries its own structural realities, its own institutional requirements, and its own renovation process.
Multi Construction Co. plans every Manhattan project around these realities before construction starts — not while it is underway.
"It is more than a passion project. It is more than a creative vision realized. It is Multi."

The Multi Construction Co. Advantage
01
Co-op board submissions, condo alteration agreements, Landmarks Preservation Commission filings, and NYC DOB permit requirements. We have navigated all of it. We prepare the documentation your building requires before we start, so board approvals and permit filings run on a schedule, not a delay.
02
Structural, plumbing, electrical, tiling, carpentry, and painting are handled by one team under one contract. In a Manhattan building where every trade needs to coordinate separately with building management, having one contractor accountable for all of it keeps your project on schedule and removes the finger-pointing that multi-contractor projects invite.
03
Full NYC contractor licensing, general liability insurance, and workers’ compensation coverage on every project. We provide the documentation your building management and co-op board require before work begins, including certificates of insurance with the building named as additional insured.
04
Pre-war Manhattan buildings regularly conceal conditions behind walls and under floors that are not on any drawing. We build discovery contingencies into every project estimate. When conditions are found, you get a clear explanation and an agreed scope change, not an inflated invoice mid-project.
05
We handle substantial renovation projects that require planning, permitting, board coordination, and skilled execution. If your Manhattan project is in that range, we are built for it.

Have questions? We’ve answered some of the most common ones.
In most Manhattan co-op buildings, yes. Boards typically require an alteration agreement, architectural drawings, contractor licensing and insurance certificates, and a renovation deposit before any work begins. Approval timelines run 4 to 10 weeks depending on the building. Multi Construction Co. prepares complete board submission packages and has completed this process across multiple Manhattan co-op buildings.
Bathroom renovations in Manhattan typically range from $20,000 to $50,000. Kitchen renovations range from $40,000 to $100,000 or more depending on scope and materials. Full apartment gut renovations in pre-war buildings typically start at $150 per square foot for mid-range work and go higher for high-end finishes. We provide detailed line-item estimates before any contract is signed.
Large portions of Manhattan — Greenwich Village, SoHo, Tribeca, Carnegie Hill, the Upper West Side, and others — are within Landmarks Preservation Commission-designated historic districts. Exterior alterations visible from a public street in these areas require LPC approval before work begins. Interior renovations are not subject to LPC oversight. We handle LPC filings as part of our project scope when they apply.
A bathroom remodel takes 3 to 5 weeks. A kitchen renovation takes 5 to 8 weeks. A full apartment gut renovation takes 3 to 6 months, accounting for board approval, permit filing, and the logistics of working in a multi-unit Manhattan building. We give you a realistic timeline upfront that includes all building management constraints.
Yes. We work with residential homeowners, co-op and condo owners, commercial property owners, and property managers across Manhattan. For commercial projects, we structure work schedules to meet lease timelines and minimize disruption to building tenants and operations.
Yes. Multi Construction Co. is fully licensed and insured to perform renovation work in New York City including residential co-ops, condominiums, and commercial buildings.
