Forest Hills has a reputation for stability. Co-op buildings have long-standing boards, mature trees line the streets, and Tudor-style homes sit behind hedges in the Gardens. That stability shapes how renovations work here: people tend to renovate once and renovate well, and the rules of the building or the community matter as much as the design.
This page is for owners in ZIP 11375 planning a full-apartment or whole-home renovation: gut, tile, flooring, paint and custom millwork. It covers the two main building types, the paperwork co-ops expect, how to write a scope that protects you, hidden costs, and typical 2026 planning costs. Figures are as of October 2026 and are planning ranges; a written, itemized quote governs.
Many Forest Hills apartments are in pre-war buildings with elevators, lobbies and boards that have been through hundreds of renovations. Units tend to be generous: separate dining rooms, long hallways, multiple closets and good ceiling heights. The construction is typically masonry with plaster walls, original radiators and cast-iron risers. Boards generally require an alteration agreement, drawings by a licensed architect or engineer, a licensed and insured contractor, a certificate of insurance and often a refundable deposit.
For gut-level work in these buildings, see our page on co-op and condo gut renovations in Forest Hills.
The Tudor-style houses of Forest Hills Gardens and nearby blocks are wood-framed with brick, stucco or half-timbered details, slate or tile roofs, leaded or casement windows and original woodwork. They offer character and demand care. A renovation is rarely only interior: roof, windows, gutters and drainage are all part of the conversation. Forest Hills Gardens is a distinctive planned community with its own design review for exterior changes, so confirm what applies to your property before you design. Interior work follows standard NYC permit rules.

The most common delay in a co-op renovation is not construction; it is paperwork. Our guide to the certificate of insurance for NYC renovations goes into detail. In short:
A certificate of insurance protects the building and neighbors if a pipe breaks, a fire starts or a worker is injured. Boards enforce requirements because they have seen what happens without them. If a contractor cannot produce a certificate quickly, treat that as a sign.
Residential remodeling in NYC requires a Home Improvement Contractor license from the Department of Consumer and Worker Protection. See the DCWP's license checklist for requirements, and ask any contractor for their license number before signing.
A scope of work is the document that makes a bid comparable and a project manageable. Our guide to writing a scope of work for your renovation includes a template. For Forest Hills co-op apartments, the key elements are:
These are typical 2026 planning ranges for NYC, not quotes.
| Scope | Typical 2026 planning range | Forest Hills note |
|---|---|---|
| Cosmetic refresh | $100-$250 per sq ft | Paint, floor refinishing, fixtures |
| Mid renovation with kitchen and bath | $200-$400 per sq ft | Typical co-op renovation |
| Full gut, all-in | $250-$500+ per sq ft | New systems, floors, millwork |
| High-end or structural | $500-$1,000 per sq ft | Layout changes, custom stone and millwork |
| Interior demolition and haul-away | $8-$30 per sq ft | Elevator hours and debris |
Design, engineering and expediting often add roughly 15-25%. Component ranges: hardwood installed $12-$28 per square foot (refinishing $4-$10), tile floors $20-$45, shower walls $30-$80, full bathroom $30,000-$60,000+, kitchen $25,000-$85,000+, and interior painting for a 3-bedroom roughly $6,000-$12,000. Larger Forest Hills apartments naturally sit toward the higher dollar totals even at moderate per-square-foot prices.

The NYC renovation cost guide for 2026 and the renovation ROI calculator help you set and test a budget.
Our guide to hidden costs in NYC renovations and budget fixes lists many. For Forest Hills, plan for:
A contingency of roughly 10-15% of construction cost is a sensible planning figure for older buildings. Hold it separately, and track every draw.
A co-op renovation is a performance in front of an audience: the board, the managing agent, the super and every neighbor who hears the work. A Tudor renovation is a long-term commitment to a house you intend to keep. In both cases the cost of a shortcut falls on the owner, usually later.
N.Y. Renovation Services is a licensed and insured design-and-build contractor. We take projects from blueprints to the final coat of paint with an in-house team, handle permitting and co-op or condo board paperwork, and give you transparent, itemized pricing in a detailed contract with no hidden fees. For Forest Hills, that means:
Think about what the alternative looks like in a co-op. A contractor who shows up without the right certificate of insurance delays your start by weeks. One who underestimates the elevator schedule blocks the lobby and annoys the board. One who skips the hazmat survey risks a stop-work order. One who cuts a plaster ceiling without a repair plan leaves you with a crack that returns. A handyman who agrees to "take care of everything" without a license or a Design Professional leaves the filing, and the liability, with you. The professional approach costs more on paper and less in practice, because the delays, repairs and disputes it prevents are the expensive part of renovation.
Residents of long-established buildings tend to value discretion, tidy jobsites and clear communication. We build those into the process: daily cleanup, a single point of contact and weekly updates. If your building has a superintendent or managing agent who has dealt with us before, even better, but we do not rely on reputation alone. We rely on paperwork, preparation and accountability.
| Phase | Typical duration | Notes |
|---|---|---|
| Walkthrough and estimate | 1-2 weeks | Free; site walk and written scope |
| Design and drawings | 3-8 weeks | Registered architect or engineer |
| Board and DOB approvals | Weeks to months | Simple filings take weeks, complex ones months |
| Surveys and abatement | 1-4 weeks, if needed | Before disturbing suspect materials |
| Demolition and rough-in | 3-6 weeks | Elevator hours and debris |
| Tile, flooring, millwork | 4-8 weeks | Includes waterproofing and finish cure |
| Paint, punch list, cleaning | 2-4 weeks | Painting is last |
A full-apartment gut typically takes four to nine months in total. A kitchen takes six to twelve weeks, a bathroom three to six, tile in one bathroom one to two weeks including waterproofing cure, and hardwood installation three to seven days plus finish cure. Interior painting of a 1-3 bedroom apartment takes two to seven working days.
Most construction needs a DOB permit filed through DOB NOW: Build by a registered Design Professional; the Department of Buildings explains how to obtain a permit. Industry reports state DOB reinstated, effective January 26, 2026, a board attestation inside DOB NOW: Build confirming alterations are board-approved; confirm with the DOB and your managing agent. If you are unsure whether your scope needs a permit, Do I Need a Permit? is a good first stop.
Forest Hills interiors tend to be traditional with updates. These are choices we see work well.

You do not need to have decided everything. Start with the building, a few photos and your top priorities.
When you meet us, we will ask about your building's rulebook, your timeline and your priorities, and we will bring a clear idea of how to sequence the project around them. We will also talk candidly about the trade-offs: a larger kitchen may mean moving plumbing, which means board approval and a longer schedule; hardwood throughout looks wonderful but may require a sound underlayment that adds cost; custom millwork takes weeks to fabricate and should be ordered early. Our job is to give you the information to make those choices before they become expensive, and to document the choices you make so that everyone, including the board, is working from the same plan.
The estimate is free and carries no obligation. We will tell you plainly what we think is worth doing in your building, what can wait and where a smaller scope meets most of your goals. When you are ready, get your free estimate.
