A Private Pricing Opinion — what your apartment at The Byron would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
The Byron is a full-service East 30s cooperative: a 134-unit, full-service post-war cooperative on a quiet block between Lexington and Third, where pieds-à-terre are permitted and financing runs to 75% of the purchase price. Compare the building’s postwar layouts, 24-hour staff, roof deck and listing-reported policies with specific nearby condominiums; no two-to-one price ratio or stable through-cycle discount is established here.
The conversion history is unusually well documented in our archive. The offering plan on file in The Roebling Research Library was first offered June 4, 1982 — structured as an eviction plan under Section 352-eeee, with 89,500 shares allocated across 134 apartments and an FHA regulatory agreement governing the building's mortgage, complete with required replacement-reserve and general-operating-reserve funding. The first amendment, also on file, is a period piece of early-1980s conversion mechanics: a dual-track structure offering tenants a reduced share price under an eviction plan (Part I) or, failing the 35 percent tenant threshold, a non-eviction plan (Part II); a $2.5 million Citibank end-loan commitment for purchasers; a working capital fund raised from $135,000 to $250,000; and a long-term sponsor master lease of the ground-floor commercial space — 49 years under the eviction structure, 25 years under the non-eviction alternative. The conversion completed in 1984 per listing records.
What the building offers today is structural rather than glamorous: large post-war layouts with deep closets, maintenance to be verified from current schedules and compared with the actual services provided, and a location one block from the 6 train with Grand Central a ten-minute walk north. For buyers priced out of the condo stock on Third Avenue — or co-op buyers who want flexibility without a Park Avenue board posture — the Byron is consistently on the shortlist.
Architecture and unit composition
The building rises 20 floors per city records in grey brick above a one-story brown-brick retail base, with a canopied entrance and sidewalk landscaping. The architectural identity is plain post-war; the original architect is not firmly documented in public records, and we decline to guess. The mix runs from studios through two-bedrooms — many produced by combination — with the post-war virtues the type is known for: defined foyers, generous closets, and unbroken wall planes that furnish easily. Cooling is by through-wall and window units rather than central air. Upper-floor lines catch open city outlooks, including Empire State Building views on west-facing exposures per listing records; the roof deck carries the building's signature panorama.
Building operations
Full-service on the essentials: 24-hour doorman, live-in superintendent, central laundry, private storage, bike room, and the landscaped roof deck. There is no garage, no fitness room, and no balcony inventory — buyers comparing with specific condominium towers should evaluate actual carrying costs alongside differences in amenities. The ground-floor retail is a separate commercial component with a conversion-era sponsor master-lease structure disclosed in the plan amendment on file; your attorney should confirm the current ownership and lease status of the commercial interest during diligence. The offering plan, by-laws, proprietary lease, and amendments are on file in The Roebling Research Library.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2026 to date) cleared a median $847/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
The policy stack is the headline. 75 percent financing, pieds-à-terre, co-purchase, guarantors, and gifting are all permitted per listing records — a flexibility profile closer to a condop than to the corridor's stricter co-ops. For parents buying with or for children, and for primary buyers who may later need to sublet, this framework materially widens what is possible. Verify each policy's current terms with the managing agent before offering.
Underwrite the post-war envelope honestly. Through-wall cooling, central laundry rather than documented in-unit washer/dryers, and combination-driven floor plans are the trade for the price point. Quantify any renovation premium from comparable sales and estimate the specific work required — run the Renovation Cost Calculator before bidding.
The commercial base is a diligence item, not a flaw. The conversion plan provided for a long-term sponsor master lease of the retail space; the current structure, and how commercial income or expenses flow through the budget, should be confirmed in the financials your attorney reviews.
Price the location precisely. The 6 train is one block away at Park Avenue South, Grand Central is a ten-minute walk, the M34 runs crosstown, and there is a Trader Joe's across the street — but the Queens-Midtown Tunnel approach is a few blocks northeast, and 32nd is one of the quieter blocks precisely because it sits below the tunnel traffic. Walk the block at rush hour before deciding.
Verify the fee stack. The flip tax is not documented in public records, and sublet seasoning, caps, and fees should be confirmed in writing. Run the Co-op Board Qualification Calculator against the building's financing framework before submitting an offer.
What to know if you’re selling
Lead with the carry and the flexibility. Your buyer pool includes pied-à-terre purchasers, co-purchasing parents, and first-time buyers comparing your maintenance against condo common charges plus taxes on Third Avenue. State the policy framework and the monthly math plainly in the marketing — they are the building's strongest arguments.
Compare nearby condominium and cooperative sales. Assess The Future and other corridor alternatives using dated, matched transactions, total carrying costs and current policies. Neither a deep discount nor a low rate of policy-related withdrawals is established here.
Condition transparency wins in the value tier. The spread between renovated and original-condition units is wide and visible in the building's history. Price to condition and line, and let same-building comparables — which we maintain unit by unit — anchor the ask.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
