New York City (Five Boroughs) document review
New York City is the defining condo and co-op market in the country, and the single most important diligence step is identifying the ownership form: co-ops historically outnumber condos in Manhattan's prewar and postwar stock, while new construction since the 1980s is overwhelmingly condominium. The two are governed by entirely different law — condos by RPL Article 9-B, co-ops by the Business Corporation Law plus a proprietary lease — and the financing, liens, board-approval, and cost pass-through mechanics differ accordingly.

Why New York City is different
What both share is the dense overlay of NYC Local Laws: FISP façade inspections, Local Law 97 carbon caps, Local Law 126 parking-structure inspections, Local Law 152 gas-piping inspections, and the 2027 elevator secondary-brake mandate. For most NYC buyers, the Local Law compliance posture and the master insurance policy, read together against the building's age, tell you the most about future out-of-pocket exposure.
FISP / Local Law 11 (façade, every five years, buildings over six stories), Local Law 97 (carbon caps tightening in 2030, $268/ton over the limit), Local Law 126 (parking structures, every six years), Local Law 152 (gas piping, every four years), and elevator modernization (secondary brake due January 1, 2027) overlap into large near-term capital programs. Request each status report and any associated assessment.
In a co-op you buy shares plus a proprietary lease, not real property. The building's underlying mortgage is a shared debt baked into monthly maintenance — confirm its balance, rate, and maturity, since a balloon refinance at higher rates drives maintenance up. Co-op boards can also approve or reject buyers without stating a reason, subject only to anti-discrimination law, which adds illiquidity and a board-approval contingency.
NYC master policies face 20%+ premium increases, carrier pullback, and stricter underwriting; open DOB violations and water-damage history in aging prewar and postwar buildings can trigger non-renewal. Read the master declarations, deductibles, and any non-renewal notice, and confirm whether the building carries flood coverage given post-Sandy exposure.

New York-specific guides
New York condo document review is governed by the Condominium Act, Real Property Law (RPL) Article 9-B (§§ 339-d through 339-kk). Unlike states with a statutory resale-certificate law, New York compels little at resale: the strong disclosure point is the initial offering plan accepted by the Attorney General under the Martin Act, while resales rely on the purchase contract. That means much of the work is proactive. A buyer should assemble the declaration, bylaws, two to three years of financial statements, the § 339-z statement of unpaid common charges, the insurance declarations, the board minutes where available, and — for New York City buildings — the Local Law status reports (FISP, LL97, LL126, LL152, elevator). The value is in reading these together against the building's age, because a complete package can still reveal a thin reserve, a SWARMP façade, or a coming assessment.

New York is unusual in having no comprehensive HOA or common-interest-community statute. Planned-community homeowners' associations exist as not-for-profit corporations (under the Not-for-Profit Corporation Law) or unincorporated associations governed almost entirely by their own declaration, covenants, and bylaws. The Attorney General's Real Estate Finance Bureau reviews HOA offering plans under the Martin Act, but there is no ongoing statutory regime equivalent to the condo Act for reserves, disclosure, or owner rights. For HOA buyers — most common on Long Island and in the Hudson Valley — that makes the governing documents the entire rulebook. Read the declaration for maintenance responsibility and assessment authority, and read the financials for reserve adequacy, because no statute sets a floor.

Insurance is among the most volatile risks in New York condo and co-op documents today. The statutory requirement is modest — under RPL § 339-bb the condo board must insure the building if the declaration, bylaws, or a majority of owners require it, and in practice nearly all bylaws mandate a master replacement-cost policy. The market behind that requirement is stressed: 20%+ premium increases are routine, several carriers have exited or curtailed the NYC multifamily market, and underwriters now scrutinize maintenance and open DOB violations in detail. Flood is generally excluded, and post-Sandy exposure is materially understated by legacy FEMA maps. For a New York buyer, the master policy is both a risk document and a financing document — its deductibles and coverage gaps can affect mortgage warrantability and what you need in your own HO-6.

Special assessments are the mechanism through which deferred and Local Law costs in a New York building arrive at your door. New York imposes no statutory cap on common charges or special-assessment size, and whether an owner vote is required is governed entirely by the bylaws (condo) or proprietary lease (co-op). In many buildings the board can impose a special assessment unilaterally, which is a key buyer-exposure point. The leading causes of large assessments are the NYC Local Law stack — FISP façade repairs, Local Law 97 penalties, Local Law 126 garage work, Local Law 152 gas repairs, and elevator modernization — followed by insurance premium spikes and capital shortfalls. Because meaningful assessments can occur board-only, reading the budget, financials, inspection reports, and minutes together is how you anticipate them.

Topic guides
A condo document review is the structured analysis of every disclosure document your seller or association has provided — declaration, bylaws, rules, reserve study, budgets, financials, meeting minutes, insurance summary, estoppel or resale certificate, and any pending special assessment notices. Done well, it tells you exactly what you are buying. Done in a hurry — or as a chat session against a single PDF — it misses the cross-references where real risk lives. This guide covers condominium document sets specifically, where shared building finances, the master insurance policy, and reserves drive the risk; if your property is a detached home in a planned community, the document set and the risks differ — see HOA document review.
An HOA document review reads the full association document set — declaration or deed restrictions, CC&Rs, bylaws, resale or disclosure certificate, current budget, audited financials, meeting minutes, and any enforcement history — and surfaces the items that actually affect your ownership cost, your usage rights, and your exposure to surprise assessments. HOA reviews have a different shape than condominium reviews, and treating them as the same process produces incomplete findings. This guide focuses on HOA and planned-community document sets — deed restrictions, use rights, and architectural control; for attached condominium ownership, where master insurance and shared building reserves dominate the risk, see Condo document review.
The association's master insurance policy determines what your personal HO-6 policy needs to cover — and what it does not. Deductibles, named-storm provisions, water and flood exclusions, policy form (bare-walls versus all-in), carrier quality, and loss assessment exposure all change the real cost of ownership in ways that never appear in the listing price. Reading the insurance summary alone is not enough; reading the master policy declarations page against the declaration's loss assessment provisions is where the real exposure lives. This page takes the risk-and-exposure view — how a building's insurance position could cost you, and what its insurability signals about the association; for the practical checklist of what coverage you and your lender actually need in place before closing, see Condo insurance requirements.
Special assessments are the single largest source of financial surprise in condo and HOA ownership. They can arrive formally, as a voted board action with a disclosed amount. They can arrive indirectly, as a dues increase that follows a reserve shortfall or insurance spike. Or they can arrive silently, implied by the gap between what an association has saved and what it needs — visible in documents years before any official announcement. A thorough document review identifies all three types.
