Spring is peak season to begin a co-op renovation in NYC. Weather is finally warming up, plans for the year are underway, and many homeowners want to be settled by fall. However, with many NYC co-ops, meeting a spring demolition date has far less to do with the calendar and far more to do with your board package.

If you’re aiming for a spring start, the planning should start now - and we’re here to help to streamline the process. Below is a straightforward guide to what co-op boards typically require, how long approvals really take, and how we help our clients prepare a spring start that doesn’t slip into summer or fall.

[#1]Why Spring Starts Require Winter Planning (Sometimes Earlier)[#1]

Most people underestimate how much time is needed before construction can even begin in their renovation. In NYC co-ops, the board approval process is the main variable that can swing your timeline. Even when the SOW is clear and design is settled, boards require a full submission package and usually multiple rounds of review.

If you want to start construction in spring, you should be building your board package in late fall or winter. 

That doesn’t mean you need every finish selected stat. The key is having the architectural and technical details settled in order to submit.

[#2]What Co-Op Boards Want To See In A Renovation Package[#2]

Every building has different requirements, but most NYC co-ops need a core set of documents before they’ll even put your renovation in front of the board. If anything is missing or inconsistent, review stalls. With a full-service design-build team, all of the necessities (drawings, scope, insurance, engineering letters) are coordinated and packaged on your behalf, so your submission lands complete the first time. Below are the details typically required for a full co-op submission:

Alteration Agreement + House Rules

An alteration agreement is your building’s renovation rulebook. This decisive document dictates work hours, noise limits, waterproofing standards, elevator usage, and what type of work is allowed. Thankfully, with help from a design-build team like Gallery, you don’t have to decode this hyper-specific agreement alone. We read line by line on your behalf, translating the fine print into plain English, and shape our design and build plan around those rules from day one so your project works with the building, not against it.

Full Architectural Drawings

To make sure your vision has been fully vetted, boards need to see your plan in drawing form, not just as a verbal description. Most architectural packages include:

• Existing + Proposed Floor Plans
• Demo Plans
• Reflected Ceiling Plans
• Plumbing + Electrical Plans
• Key Details (Wet Areas, Penetrations, Soffits, Etc.)

These articulated requirements are exactly why Gallery has an in-house architecture team working alongside interior design and construction from day one. After locking in your vision and adjusting according to any internal or structural challenges the building may provide, we draft the drawings, coordinate engineering, then align the scope with your building’s rules and assemble a board-ready package - all under one roof. The result is a submission that’s consistent, complete, and designed to move through approvals with few surprises as possible.

Scope Of Work (SOW)

The SOW explains what the renovation entails, detailing exactly what’s changing, why, and how. The details must be hyper-specific and fully aligned with the architectural drawings to avoid back-and-forth with your board. At Gallery, our in-house architectural team prepares this documentation, ensuring details meet board expectations, reflects building rules, and answers technical questions upfront so the review process stays on track.

Insurance Certificates

As your contractor, we’re required to provide Certificates of Insurance that match your building’s exact standards. These include general liability, workers’ comp, umbrella coverage, and any very specific additional language the board or managing agent requests. Because co-ops can be particular about wording and limits, this step can easily slow things down if handled late or incorrectly, which is why our team handles COIs proactively and directly with building management. Our goal is to provide paperwork that’s correct on the first pass and your submission isn’t held up over insurance fine print. 

Specialized Letters (Ad Hoc)

For more involved projects, boards often require add-ons like:

• Electrical Load Letter
• Structural Engineer Letter
• MEP/HVAC Equipment Specs
• Soundproofing Plan
• Landmark/LPC Notes (If Relevant)

[#3]The Real Timeline: What To Expect For Approvals[#3]

Here’s another tricky part about timing your co-op renovations. No matter how tight your submission package is, boards almost never sign off on the first pass. A typical approval sequence looks like this:

1. Submit To Building Management (They Check For Completeness)
2. Board Engineer/Architect Review (First Round Comments & Recommendations)
3. Revisions + Resubmission
4. Second Review
5. Final Board Sign-off With Conditions
   

That’s why approval timelines often land in the 8–16 week range, and possibly longer for complex renovations. For instance, if your building meets monthly and you miss an agenda cut-off, the clock adds another 3–4 weeks. Just like that. This is why spring construction starts need a submission window much earlier than most people think.

[#4]The Three Most Common Timing Traps We See[#4]

After years of helping clients navigate NYC co-op approvals, these are the three timing traps we’ve seen push out spring starts more often. Knowing them early can save months later.

Trap #1: Treating Board Submission As Something That Happens After Design

From our side, the board package starts day one, not at the finish line. If drawings and submissions wait until every finish is finalized, you lose the most valuable months on the calendar. Thankfully, we structure planning so design development and board-ready documentation move in parallel, meaning your project progresses toward approval while design details are still being refined.

Trap #2: Assuming Co-op Approvals Run On A “Normal” Timeline

Like it or not, co-op boards review on their own schedule. Some buildings meet monthly, some require two rounds with a reviewing architect, and many have hidden requirements that slow things down. Our job is to forecast your specific building’s cadence early, assemble a submission that anticipates likely objections, and build in revision cycles so your timeline doesn’t get hijacked by whatever the board’s process may be.

Trap #3: Discovering Building Constraints After Plans Are Drawn

As we’ve discussed across various articles in our Design & Reno Blog, the most expensive renovation delays happen when feasibility isn’t confirmed up front. This means electrical caps, wet-over-dry rules, HVAC limitations, shaft access, landmark restrictions, etc. We avoid that by doing a consultative walkthrough and early systems review before design settles, so your layout and scope are built around what the building will actually allow. That keeps the package clean, the approvals smoother, and the budget honest.

[#5]What To Do Now If You Want To Break Ground In Spring[#5]

Here’s how we guide clients who are aiming for a spring start:

Confirm Feasibility Early

Before anyone spends real money on full drawings or detailed finishes, we start by stress-testing the big constraints:

• Electrical Capacity / Load Limits
• Wet-Over-Dry Rules
• HVAC Condenser Options (Terrace Vs Roof Vs Sleeves)
• Landmark Or Facade Restrictions
• Structural Realities (Load-bearing Walls, Risers, Beams

We handle this through a consultative walkthrough and early systems review so we’re designing inside what the building will actually allow. For many potential clients, we do this before they even purchase their home. 

Start Drawings Sooner Than You Think

Because we have architecture, interior design, and construction management under one roof, we get architectural and MEP drawings moving earlier than a piecemeal team typically would. For spring starts, we aim to have drawings in motion during winter, so by the time you’re finalizing finishes, the technical side is already aligned with your building and ready for submission.

Build The Board Package In Parallel

While drawings are underway, our team is simultaneously assembling the co-op package. As discussed above, this means we’re reviewing the alteration agreement, confirming insurance requirements, aligning with the building’s submission format, and pulling any relevant precedent from management. That way, the admin work isn’t something we’re handling after design is done, because it’s been happening behind the scenes since day one. 

Expect At Least One Review Round

Even very strong packages get comments. Our timelines plan for that. As part of our process, we budget time for at least one round of board or reviewing-architect feedback, then handle the revisions and resubmissions on your behalf. The goal isn’t to avoid adjustments altogether (good luck), but instead make sure any board feedback is manageable, anticipated, and doesn’t derail the overall start date.

[#6]TL:DR | Your Spring Renovation Timing Overview[#6]

Ultimately, a timeline for a co-op renovation in NYC that has a goal to start in spring should follow this overview: 

• Late Fall / Winter: Feasibility Checks, Start Drawings, Gather Building Rules
• 8–12 Weeks Before Desired Demo: Submit Board Package
• 4–8 Weeks Before Demo: Round-one Comments + Revisions
• 2–4 Weeks Before Demo: Final Approvals, Logistics Planning, Elevator Scheduling
