Apartment, Co-op & Condo Remodeling in NYC

Alteration agreements, DOB filings, board approvals, freight elevator scheduling, and pre-war structural work — all handled. You renovate; we manage the building.

What we build

Four apartment scopes. One playbook.

Co-op, condo, pre-war, single-room, or full combination. The construction standard runs the same on a one-bath scope and a 4-bedroom gut — what changes is the building paperwork. We've run the alteration agreement, DOB filing, and freight elevator playbook often enough that it's now part of the timeline, not a surprise.

  • Full apartment renovation interior — open-plan living and kitchen following a complete gut and rebuild in a NYC apartment

    Full apartment renovations

    1-to-4 bedroom co-ops and condos, demoed to the studs and rebuilt: new layout, new plumbing, new electrical, new finishes. Alteration agreement and DOB filing handled in parallel with design so the build starts on schedule. Family typically relocates for the duration.

  • Pre-war Upper West Side co-op bathroom remodel with restored crown moldings and natural stone walls

    Pre-war apartment renovations

    Apartments built before roughly 1940 — plaster walls, original hardwood, casement windows, cast-iron drain stacks, steel-frame structural elements behind the plaster. We restore where possible (plaster patch and skim, hardwood sand-and-finish, casement repair) and replace only when restoration is not feasible.

  • Single-room apartment install — wide-plank engineered wood flooring set inside one room of a NYC apartment scope

    Single-room apartment work

    Bathroom-only, kitchen-only, or single-room apartment scopes inside a co-op or condo. Same alteration agreement and DOB requirements as a full gut, on a focused build window.

  • Combined-apartment renovation with custom shaker cabinetry, polished marble floor, and panel-front refrigeration in a Brooklyn unit

    Combined apartments

    Two adjacent units combined into one. DOB-permitted structural work to remove the dividing wall (sometimes load-bearing), unified mechanical systems, and a combination-specific alteration agreement.

Materials & Standards

Six standards. No shortcuts.

Apartment work runs to the same finish standard as our suburban builds — but it lives behind a layer of building rules. The six standards below hold across every scope, in every NYC building, on every floor.

  • Restored pre-war Manhattan apartment finish — original moldings preserved against custom tile detail

    Pre-war restoration.

    Plaster walls patched and skim-coated where condition allows, replaced with drywall on the original studs where it doesn’t. Original hardwood sand-and-finish before refinishing. Casement windows restored on the sash before replacement is considered.

  • Custom shaker cabinetry installed in a NYC apartment kitchen build

    Cabinetry.

    Custom millwork from partner shops; semi-custom from Rutt, Christopher Peacock, Wood-Mode on the high end. Lead times built into the design phase so cabinetry arrives the week the demo wraps — never the week before the freight elevator is booked.

  • Bookmatched marble slab — apartment vanity and countertop stock

    Stone.

    Calacatta, Carrara, statuario, Taj Mahal slab. Bookmatched walls, waterfall vanities, and mitred countertop edges templated on site. Slab delivery coordinated with the freight elevator schedule so the stone arrives the day it is set.

  • Custom tile detail installed in a NYC apartment bathroom

    Tile.

    Dry-laid mockup before adhesive. Mitred outside corners on natural stone. Hand-laid mosaic feature walls. Schluter or RedGard waterproofing membrane on every wet wall and shower floor — same standard, no exceptions.

  • Brass fixtures and pressure-tested supply lines in a NYC apartment build

    Fixtures & plumbing.

    Brass and bronze supply lines, pressure-tested before walls close. Trusted licensed plumbers — long-term partners — running rough-in for every bathroom and kitchen on co-op or condo work. Cast-iron drain-stack tie-ins handled cleanly on pre-war stacks.

  • Smart bathroom toilet and integrated controls in a NYC apartment renovation

    Smart integration.

    Heated floors, app-controlled shower valves, pre-wired smart mirrors, integrated audio, motion-sensor niche lighting. Roughed in during framing — never bolted on after tile, never approved as a board change-order mid-build.

Process

Four steps. No surprises.

Apartment timelines depend on scope, building approvals, and work-hour rules. The four-step process below holds across every scope — co-op, condo, pre-war, or combination — only the durations shift.

  1. Free consultation

    On site is best for apartment work — we walk the unit, photograph existing conditions, identify pre-war structural elements, and review what your building handbook requires. Video works for follow-up.

  2. Design and approvals

    Drawings, finish selections in three tiers, alteration agreement package (drawings, COIs, contractor disclosures, scope narrative), and DOB filing where required. We submit to the managing agent and follow up until written approval lands.

  3. Build

    Lobby and corridor protection installed before tools arrive, freight elevator reserved with building staff, dust barriers up before demo. We work inside the building’s permitted hours and on the freight schedule — every day.

  4. Walk-through and warranty

    Final punch, deep clean, building handover (final walk-through with the super or managing agent where required), and the 2-year written workmanship warranty. Manufacturer warranties on cabinetry, fixtures, and tile pass through to you.

FAQs

Common questions.

Everything we get asked about scope, timeline, materials, and how the work actually runs.

How long does an NYC apartment renovation take?

Once approval clears and demo starts, kitchen-only projects start from 2 weeks. Larger gut renovations run on a longer schedule. Timeline depends on scope, building approvals, and work-hour rules.

What are the standard NYC apartment building work hour rules?

Most Manhattan and Brooklyn buildings allow construction Monday through Friday, 9 AM to 4 PM. Some allow Saturday morning hours; most don't. Sundays and holidays are off. Hammering, drilling, and demo are restricted to certain windows within those hours in some buildings. We schedule the build around your specific building's rules — we ask for the building handbook on the consultation and plan from there.

Do you handle freight elevator scheduling?

Yes. We coordinate freight elevator reservations with the building staff, schedule large-material deliveries (cabinetry, slab stone, appliances) for the freight, protect lobbies and corridors with floor and wall covers, and pay any freight elevator fees the building charges (those are pass-through line items in your contract, not hidden in our number).

Can you remodel a pre-war apartment?

Yes — pre-war work is a substantial share of our portfolio. Pre-war apartments come with structural quirks: plaster walls that don't take drywall fasteners cleanly, original cast-iron drain stacks that need careful tie-ins, steel-frame structural elements behind the plaster, and original casement windows that often need restoration rather than replacement. We've handled all of them often enough that they don't slow us down.

What about plaster walls — can you keep them or do they have to come down?

Both options exist depending on condition. Plaster in good condition can be patched, skim-coated, and painted; the result is denser and more sound-attenuating than drywall. Plaster that's been damaged by water, has structural cracking, or has been heavily patched already is usually replaced with drywall on the same studs (or new metal-stud framing if the existing studs aren't stable). We test condition during demo and recommend per wall.

Do condos and co-ops have different rules than the buildings give homeowners?

Different governance structures. A co-op is owned by a corporation that owns the building; the homeowner owns shares and a proprietary lease. A condo gives the homeowner direct ownership of the unit. Co-ops typically have stricter alteration agreements (more board oversight, longer approval cycles, sometimes board interview requirements). Condos vary widely — some are nearly as strict as co-ops, some are quite light. We confirm the rules for your specific building during the consultation.

Do you handle insurance certificates with the required limits for the building?

Yes. Most NYC buildings require a contractor's certificate of insurance naming the building, the managing agent, and any related entities as additional insureds, with specific liability limits ($1M/$2M is common, $5M required by some high-end buildings). Our certificates are issued by request from the broker and sent directly to your managing agent. We do this multiple times a month — it's standard.
