Just Went Into Contract on an NYC Apartment? Here's What to Do Before You Close

The 30-to-60-day window between contract and closing is the most underused stretch of any renovation timeline. Most buyers wait until the keys are in hand before they think about design — and by then, they've already lost six weeks of lead time on the items that take longest, plus the chance to negotiate alteration agreements before the board has any leverage to slow things down.

If you've just gone into contract on a New York City apartment, the design work doesn't start at closing. It starts now.

Get the floor plan in your hands today

The first hour of work happens with the floor plan, not the apartment. Request a copy from the seller's broker — most listings have it from the original offering plan or the most recent appraisal. If they don't, the building's managing agent will. Co-op and condo records typically include a plan with structural elements, wet walls, and any prior alterations on file.

Walk through it with a designer. The conversations that come out of that initial review will reframe your sense of the apartment: where the layout works, where it fights you, what's structural (which usually means expensive), and what's cosmetic (which usually means fast). You'll come out with a clear sense of whether you're looking at a paint-and-furnishings refresh or a wall-moving renovation — and roughly what each costs.

Read the alteration agreement before closing

If it's a co-op, the alteration agreement is the document that governs your right to renovate. It will dictate timing windows, required deposits, board approval processes, summer-only construction restrictions, and indemnification language. Some buildings are easy to work with. Others have ten-page agreements with $25,000 deposits, six-month approval timelines, and weekend-only work rules that will quietly add three months to your project.

Get the alteration agreement from the managing agent or your real estate attorney while you're still in contract. If the terms are restrictive, you want to know now — both for budget planning and because some buildings are negotiable on specific points if you raise them before you're already a shareholder.

Order the things that take 14 to 24 weeks

Custom furniture, stone slabs, certain plumbing fixtures, integrated appliances, and bespoke millwork all have lead times that ignore your closing date. Custom upholstery from most workrooms: 14 to 18 weeks. Marble slabs sourced from Italy, then templated, then fabricated, then installed: easily 16 to 24 weeks from the moment you commit. If you wait until closing to start ordering, you're guaranteeing an empty apartment three months after you move in.

The pre-close window is when these orders should be initiated — at least in principle. A designer can scope which items genuinely need to start now versus which can wait. The point is to have the schedule visible before closing day, not to find out about it three weeks later when you realize the dining table won't arrive until October.

Interview your contractor while you have time to think

Bidding out a renovation properly takes four to six weeks: scope definition, request for proposals to three GCs, walk-throughs, references, contract negotiation. If you do this in the rush after closing, you'll either go with whoever responds first or you'll lose another month before the work begins. Done during the contract period, the right contractor is selected and onboarded before you have keys.

The same applies to architects (if you'll need one for structural work), expediters (for building permits and Department of Buildings filings, particularly in older buildings or anything involving plumbing relocation), and your trade team — electrician, painter, finish carpenter. Each of these relationships takes time to vet correctly.

Schedule against the closing date, not against itself

Build a renovation calendar that anchors to your closing date and works forward, week by week. Mark when board approval will be filed, when it's likely to be granted (typically 4 to 8 weeks), when construction can start, when each major trade is scheduled, when long-lead items are due to arrive, when install day will be. Most projects that go over schedule do so because the calendar was built optimistically, not because anything specific went wrong.

A realistic calendar built before closing also gives you something to negotiate with — if your seller is flexible on the closing date, sometimes a two-week shift gets you board approval lined up exactly with the start of summer construction season, or out of an awkward winter slot.

Decide whether the apartment is your primary or your pied-à-terre

The design priorities shift meaningfully depending on how the apartment will live. A primary residence is engineered for daily use — durable finishes, storage that disappears, lighting layered for work and rest, acoustic considerations across rooms. A pied-à-terre is engineered for short stays — hospitality-grade beds and baths, low-maintenance finishes that don't need attention between visits, art that doesn't require climate control, smaller refrigerator. Both can be beautiful; they shouldn't be designed the same way.

If you're a pied-à-terre buyer, the pre-close window is also when you decide on a furnishing approach. A turn-key project on the right timeline can have the apartment ready to live in three to six months after closing. A custom renovation will take longer but yields a property genuinely tailored to how you use it.

The work after closing is when the bill arrives

The pre-close window is when planning is cheap. Every hour spent on the floor plan during contract is an hour saved on the back end — and the difference between an apartment that's finished six months after closing and one that's still under wraps a year in is almost entirely about what happened in the 30 days before keys.

If you're in contract right now, book a consultation. We'll walk the apartment together (virtually if needed), read the alteration agreement with you, and put a real timeline on what your project actually looks like.
