Data refresh; inspections for October 8–14
All city records refreshed on October 16: 1,008,370 buildings and 111.9 million records. The new weekly inspections page covers October 8–14: 421 restaurant inspections, 8 closures by the health department, 10 reopenings and 57 with evidence of mice. On October 12 the Department of Buildings republished its certificates of occupancy and elevator records; the duplicate copies that produced were caught by our checks and removed before publishing.

Duplicate records removed from two sources
Two city datasets were listing the same record more than once in building histories: HPD's Alternative Enforcement Program list (republished monthly, so each month's copy appeared as a new entry) and DEP asbestos-abatement filings (a status update appeared as a second filing). Both now show one entry per real record; about 16,000 duplicate entries were removed from building timelines. All city records were refreshed on October 11.

Rents on neighborhood pages
Each neighborhood page now shows the approximate median monthly rent (rent plus utilities) that households there pay, from the Census Bureau's 2020–2024 American Community Survey. It includes rent-stabilized and long-time tenants, so asking rents for vacant apartments are usually higher.

Sale prices, mortgages and co-op finances
Neighborhood pages now show the median recorded sale price over the last year, separately for houses and for apartments, with the range the middle half of sales fell in (NYC Department of Finance sales, excluding transfers under $10,000 and suspected package sales). Building pages now show the most recent mortgage recorded against the lot, with its lender and a link to the recorded document, and for co-ops and condos the city's own estimate of what the building would earn and spend as a rental, the figure it uses to value the building for property tax. Asking rents and maintenance charges are not public records, so they are not here.

Neighborhood pages
196 new pages, one for each residential neighborhood in the city as drawn by NYC City Planning. Each shows how its buildings grade, the most distressed buildings, the largest managing agents, how many buildings are within about a ten-minute walk of a subway station, restaurant grades and mice findings, its ZIP codes and the neighborhoods next door. Building pages and ZIP pages now link to their neighborhood.

Weekly refresh; first grade changes on This week
Data refreshed on September 24. The second weekly inspections page (September 15–21) is the first to list restaurants whose grade card changed since the week before: 198 of them, including 16 that went from Grade Pending to a C. Some of those changes are grades DOHMH decided this week for earlier inspections, and the page now says so.

Getting around
Every building page now shows the nearest subway or Staten Island Railway station with its lines and a rough walking time, the nearest bus stop with a local route, the nearest Citi Bike station, any mapped bike lane close by, and the elementary and middle school zones from the Department of Education's 2024–25 maps, with a link to confirm on the DOE's own school search. Distances are straight-line, not walking routes.

Fewer crawlers, more room for people
Two nights of automated sweeps from SEO-tool networks pushed the building pages past what the free hosting tier serves in a day, and real visitors saw errors during those hours. Three more SEO crawlers are now asked to stay away in robots.txt, and their networks are challenged at the edge. Nothing changes for search engines or for people.
Sep 18, 2026
Lived here? Would you rent here again?
Every building page now asks one question of readers who have lived there, yes or no. It is an unverified reader poll, the first thing on the site that does not come from city records: answers are shown separately from the grade, never change it, and appear only once five people have answered, as a range and a rounded share rather than exact counts. Nothing personal is stored; the About page has a new Privacy section explaining exactly what is kept.

This week in restaurant inspections
A new page each week listing what DOHMH did in the latest seven days of published inspections: restaurants closed and reopened, restaurants cited for evidence of mice, scores in the C range, Grade Pending cards, and, from the second week on, letter grades that changed since the week before. Every week keeps its own page. The Mice Map shows the headline numbers with a link.

PLUTO and DOF tables now refresh on a schedule
The tax-lot spine (PLUTO) refreshes weekly with everything else; it had been on an August version and now carries the city's August 24 release. DOF assessed values and tax exemptions refresh every four weeks.
Sep 17, 2026
Duplicate DOB NOW permits removed
About 130,000 permit records from the DOB NOW system were listed more than once, because the city re-issues the same rows under new identifiers on every weekly update. Building pages, permit counts and the ten-year activity figures no longer count them twice. Older BIS permits were not affected.
Sep 17, 2026
The weekly refresh watches for silently growing tables
The duplicate permits slipped through because every table's size check has a wide tolerance. Each refresh now compares every table with the week before and flags anything that moves by more than three percent, so a quiet creep like this is caught the week it starts.

What's new in the navigation
This log now has its own link at the top of every page on both sites, next to About.

Mice Map fixes
The Mice Map loads again when opened from the buildings site. A search typed while the map is still loading now applies as soon as it finishes, and screen readers announce loading and the result count. When several restaurants share a dot, the hover note now says they are on the same tax lot rather than at the same address, since a large lot can span several addresses.

ZIP code links only where a ZIP page exists
Building pages link to their ZIP code page only for the 174 ZIP codes that have one, instead of linking every ZIP and leading to a missing page for the rest.

Faster first load on the Mice Map
The map's data now loads as a separate cached file after the page itself appears, so on a slow phone connection the page is readable in well under a second instead of only after the whole map download. The data itself is unchanged.

Closures shown on the Mice Map and on building pages
When the Health Department's latest record for a restaurant is a closure, the slip now says so first, with the date, and the letter becomes its last letter grade. Clicking a dot in a crowded building always shows the restaurant you picked first, with a Show all control; the dot you hover is the restaurant you get.

Pages with six or more sections get a one-line menu of anchors grouped as current issues, ownership and money, systems and site, history, and reporting to 311.

Landlord spelling variants merged
A managing agent registered under several spellings from the same business address is now one portfolio, with the other spellings listed on its page. Agents that file from the same office but are not the same company are listed under Registered from the same address, without claiming they are related.

Ten-year activity by category, heat complaints by winter, where the building sits among its peers on the grade scale, and a locator map linking into the city map.

Restaurant pages and ZIP restaurant lists
Every inspected restaurant in the city has a page with its grade history, inspections, violations and the building it is in. Each ZIP code page lists its restaurants, worst card first. Grade Pending cards are shown as such on both sites instead of a stale letter.

Accessibility and honesty pass
Landmarks and labels for screen readers, a keyboard route to the map's building data, real 404 pages, compact tables that do not scroll on phones, and copy that says exactly what the records support.

Redesign, 311 reporting, food-poisoning view
A quieter design across both sites. Building pages carry a guided handoff to 311 with the address ready to copy. The Mice Map gained a third view for 311 food-poisoning reports and a click-through from any restaurant dot to its building.

Shoreline fix on both maps
The land outline was rebuilt from the city's full-resolution borough boundaries; 4,029 lots that had been drawn in the water are on land.

Energy grades and stormwater flood maps
Building pages show the city's LL33 energy letter grade and whether the lot is in the DEP stormwater flood maps under current and future sea-level scenarios.

A page for every landlord portfolio
Five thousand managing-agent portfolios have their own page with grades, open violations, evictions, litigation and heat complaints across their buildings.
