When HPD approves a housing violation, a paper trail begins. The condition may be corrected quickly or slowly — and after the work is done, the owner still has to formally certify to HPD that it has been corrected.

Brix measured how long that takes, using NYC HPD violation data. We analyzed 455,279 violations approved between January 1, 2024 and March 31, 2026 across 104 large landlord portfolios. Of those, 358,428 reached certification during the study period. Among them, the median time from HPD approval to owner certification was 106 days.

That is the headline number. It is not the most important finding.

106 days

The median time for a NYC landlord to certify a housing violation.

358,428 certified violations across 104 large landlord portfolios, approved Jan 2024 – Mar 2026.

What "106 days" measures

This is a study of certification time: the days between HPD approving a violation and the owner certifying the condition corrected.

Certification is an administrative event, not an independently verified repair date. A repair may happen before certification, and an open violation can stay open while certification, reinspection or dismissal is pending. So 106 days does not mean an apartment necessarily went unrepaired for 106 days. It means 106 days elapsed in the record.

For portfolio comparisons we required at least 500 closed violations in the study window, which left 104 portfolios. Buildings sold during the window are being excluded in the next re-run of the analysis so that a seller's violations are never credited to a buyer.

The spread is the story

The median across the 104 portfolio medians was 112 days. A quarter came in at 96 days or less. A quarter took 122 or more. The fastest portfolio's median was 81 days; the slowest, 293 — a 3.6× spread under the same process.

The long tail matters: 9 portfolios had medians of 200 days or worse, holding 56,583 violations from the study window. We are not naming that end of the table yet: a slow median can reflect one distressed building, a receivership or a mid-repair transfer, and that separation work isn't finished.

Fast certification does not mean a small backlog

Certification-time medians only describe violations that reached certification. Violations still open at the end of the window contribute no time at all. A portfolio can close many violations quickly while harder or newer cases stay open.

That is why Brix pairs speed with a second measure: the share of study-period violations still open at the end of the window. That is where the most striking contrast in the data appears.

81 days versus 84 days — and a completely different backlog

Two things that sound contradictory can both be true.

Across 73 buildings where HPD registrations list Ved Parkash as owner or head officer, the median certification time was 81 days, with just 4.2% of violations at least 180 days old still open.

Across 30 buildings in East Harlem, Emerald Equity Group moved at almost the same speed: 84 days.

Yet 36.9% of Emerald's violations at least 180 days old were still open — including 109 Class C violations, the city's most serious tier: conditions HPD rates immediately hazardous.

Both open shares count only violations at least 180 days old at the end of the window, so every portfolio had equal time to correct, and exclude buildings sold during the study period.

Similar speed. Very different backlog.

Two days apart on certification speed. Forty-six points apart on what's still open.

Speed vs. open backlog

Source: NYC HPD violation data, Jan 2024–Mar 2026, Brix analysis. Parkash 242 LLC is part of Ved Parkash and shown once. Managing agents are not counted as landlords. Open shares are preliminary pending the 180-day re-run.

Why the two portfolios look so different

A certification is the landlord's filing that a condition was corrected — not the city confirming it.

Speed only counts what gets certified. Ved Parkash certified 95.8% of its violations at least 180 days old. Emerald certified 63.1%. The rest never enter Emerald's 84-day median, so the median looks fast while the backlog stays.

Picture ten violations each. Landlord A certifies nine of them, with a median of 81 days. Landlord B certifies five, with a median of 84 days, and the other five stay open. On speed, they look almost identical. Only one of them has cleared the list. (An illustration of how the median works, not a claim about which violations either landlord left open.)

Size doesn't explain the gap. The open share is a percentage, not a raw count.

Emerald shows why one metric is not enough

The 84-day figure asks: among violations that reached certification, how quickly did the middle one get there? The 36.9% figure asks: how much of the cohort aged 180+ days was still open when the window closed? They measure different subsets of the same portfolio.

84 days. 36.9% still open. Both are true.

Emerald Equity Group, violations approved Jan 2024 – Mar 2026. Preliminary — open share will be re-measured on violations at least 180 days old.

Certification speed tells you how fast the paperwork moves. Open-violation share tells you how much is left behind. That is why Brix doesn't collapse these measures into a single score.

Recent flow and total stock are different things

This study measures a defined recent cohort. A landlord can do well on recent certification speed and open share while still carrying a large backlog from older years — or the reverse. Other landlord lists may use different time periods, ownership definitions or severity weightings, so the same landlord can rank very differently depending on the question. We looked at this in how the city's watchlist ranks landlords versus portfolio-wide rollups.

Ownership structure changes what you see

Brix analyzes portfolios at the level of verified consolidated ownership, because one landlord group can operate through many LLCs. Parkash 242 LLC, for example, is counted within the consolidated Ved Parkash portfolio, not as a separate landlord. Managing agents are never counted as landlords. Without that step, one ownership group can appear several times in the same ranking. You can trace the LLCs behind any address with who owns your building.

The more serious the class, the faster it tended to reach certification. But an 86-day median for immediately hazardous violations is still a long administrative interval, and certification time is not the date of physical repair.

A note on the still-open share

The still-open figure is a snapshot at the end of the study. Violations approved late in the window had less time to reach certification, so it is not a lifetime failure rate. That is why the open shares above count only violations at least 180 days old, so every portfolio gets equal time to correct.

What this analysis does not tell you

It does not measure the day a physical repair happened, or judge repair quality. It doesn't capture problems that were never reported or inspected. An open violation doesn't necessarily mean the condition remains unrepaired. And a portfolio median says little about any single building — which is why Brix brings the analysis back to the building itself.

The larger finding

The headline is 106 days. The lesson is that no single number describes how a landlord handles violations. Emerald Equity Group and Ved Parkash certified at almost the same speed — 84 days versus 81 — while their open shares were 36.9% versus 4.2%. A ranking on speed alone would miss that. The fuller picture requires both.
