Multifamily Renovation

At Monarch Contracting Group, we work with the people responsible for operating and maintaining multifamily properties in New York City. We're not set up for one-off homeowner jobs, we're built for property managers running occupied buildings, landlords managing renovation timelines across multiple units, co-op boards navigating alteration agreements, and condo associations coordinating building-wide capital improvements. Our licensed team handles every trade in-house, giving you a single accountable contractor for unit renovations, common area upgrades, amenity improvements, and full building capital projects, from DOB permit filing through final inspection and sign-off.

Renovating Multifamily Properties in NYC Takes More Than a Contractor

Working in occupied multifamily buildings in New York City involves a layer of complexity that most general contractors aren't equipped for. NYC Department of Buildings permits are required for virtually any structural, plumbing, or electrical work, and, in co-op and condo buildings, work must often be approved by the board and comply with an alteration agreement before a single tool enters the unit.
Tenant coordination matters just as much as the physical work. Scheduling around occupied units, observing building noise restrictions, protecting common areas during construction, and keeping residents informed throughout the project all affect how smoothly things run and how your tenants experience the process.
Monarch Contracting Group has direct experience navigating these requirements across all five boroughs. We handle DOB filings, work within board-mandated windows, coordinate with on-site supers and managing agents, and keep building management updated throughout every phase. The result is a renovation that gets done right, on time, and without putting you in the middle of every decision. Learn more about our general contracting process.
