New York condo and co-op buying checklist
Buying in New York means branching first on ownership form — condo, co-op, or HOA — because the law, liens, financing, and hidden costs differ fundamentally between them, then working a document set the law largely will not hand you. New York compels little at resale: no statutory resale certificate, no reserve-study mandate, and no right to cancel after reviewing documents.

That puts the weight on the offering plan and amendments, the financials, the managing agent's package, and — for NYC buildings — the Local Law stack. This checklist separates what is typically provided from what you must request proactively, and centers the questions that decide most New York deals: the co-op underlying mortgage, the NYC Local Law obligations behind the next assessment, the hard-market insurance posture, and sponsor control.
Branch first on ownership form
Before anything else, confirm whether you are buying a condo (real property, conventional mortgage, common-charge lien junior to the first mortgage under § 339-z), a co-op (shares plus a proprietary lease, a share loan with an Aztech recognition agreement, a senior maintenance lien, and a building-wide underlying mortgage), or an HOA (governed almost entirely by its declaration, with no comprehensive statute). Many of the most important questions — financing mechanics, lien priority, board-approval power, and hidden building debt — have different answers in each branch. Co-ops are also exempt from the Property Condition Disclosure Act, since the buyer purchases shares rather than real property.
The documents to assemble
Because New York has no statutory resale packet, assemble the set proactively. Get the governing documents (condo: declaration, bylaws, house rules; co-op: certificate of incorporation, bylaws, proprietary lease, house rules), the offering plan and every amendment, two to three years of CPA-certified financial statements and the current budget, and the common-charge or maintenance statement with arrears — for a condo, the § 339-z statement of unpaid common charges that caps your liability. Obtain the managing agent's condo questionnaire and waiver of the right of first refusal (condo) or the board package and Aztech recognition agreement (co-op), the reserve balance, and any board minutes available. Request the underlying-mortgage terms for a co-op.
The NYC questions that decide the deal
For a New York City building, the next special assessment usually hides in the Local Law stack, so answer four questions before you commit. What is the FISP / Local Law 11 façade status (Safe, SWARMP, or Unsafe), and is any sidewalk shed up? What is the Local Law 97 carbon-cap posture and projected penalty, given the sharp 2030 tightening? Are the Local Law 126 garage, Local Law 152 gas, and elevator (2027 secondary-brake) obligations funded or pending? And what is the master-insurance posture — was the building non-renewed or hit with a 20%+ increase, and is the deductible high enough to affect financing? For a co-op, add the decisive fifth question: what are the underlying mortgage's balance, rate, and maturity?
Read everything together and rely on contingencies
No single New York document tells the story. Read the reserve contribution against the budget and financials, the FISP and Local Law reports against the reserves and minutes, the insurance declarations against any non-renewal notice and the flood-zone position, and the § 339-z or maintenance statement against the building-wide arrears rate and any approved assessment. Confirm the sponsor-held percentage and board-control status, and for coastal or Sandy-exposed buildings check the NYC Flood Hazard Mapper. Because New York provides no statutory rescission, your protection is the contract's contingencies — attorney review, financing, and a co-op board-approval contingency — so build adequate review time into the offer and use them deliberately.

Cross-reference
The risk lives in the contradiction between documents.
An assessment in the minutes but not the estoppel; a reserve the budget never funds.
