Top 7 Reasons Landlords Get HPD Violations — And How to Avoid Them

HPD violations can hit your wallet hard — with fines reaching $1,000+ per violation and potential housing court appearances that drag on for months. Yet most NYC landlords keep making the same preventable mistakes that trigger these costly violations year after year.

You’re about to learn exactly what HPD inspectors look for and how to stay ahead of violations before they happen. This guide breaks down the most common violation triggers and gives you actionable steps to protect your properties.

Here’s what we’ll cover:

• The top 4 environmental hazards that account for most of all HPD violations (pests, mold, heat/hot water, and lead paint)
• Critical safety violations that inspectors check first (window guards, smoke detectors, and self-closing doors)
• Practical prevention strategies and compliance timelines for each violation type

We’ve helped hundreds of NYC property owners track and resolve their HPD violations through ViolationWatch. Our platform sends you instant alerts when violations hit, so you never miss critical deadlines. Plus, you get step-by-step resolution guidance from compliance experts who know HPD inside and out.

Environmental Hazards That Trigger Most HPD Violations

Environmental hazards plague NYC rental properties more than any other violation category. These four issues alone generate thousands of violations each year, costing landlords millions in fines and repairs. Let’s break down each hazard and how you can stay compliant.

1. Pest Infestations — The Silent Property Value Killer

Pest problems spiral out of control fast. What starts as a minor roach sighting can transform into a building-wide infestation that triggers multiple HPD violations and tenant complaints.

The New York City Department of Housing Preservation and Development takes pest violations seriously because they directly impact tenant health and safety. Common violations include:

• Rodent infestations (mice, rats)
• Insect problems (roaches, bedbugs, flies)
• Failure to address pest complaints within required timeframes

The real problem? Pests spread between units through walls, pipes, and ventilation systems. One untreated apartment can contaminate an entire building within weeks.

How to Prevent Pest-Related HPD Violations?

Your pest prevention strategy needs both proactive measures and rapid response protocols.

Monthly Prevention Checklist:

Pro tip: Contract with a licensed exterminator for monthly preventive treatments. Document every visit — HPD wants proof you’re addressing problems systematically, not just reacting to complaints.

2. Mold Growth — The Health Hazard You Can’t Ignore

Mold violations carry serious weight because they pose immediate health risks. HPD categorizes mold as a Class B or C violation depending on severity, with fines starting at $250 per violation.

Mold thrives in NYC’s older buildings where moisture problems run rampant. The biggest culprits:

• Leaking pipes behind walls
• Poor ventilation in bathrooms
• Window condensation issues
• Roof leaks that go undetected

Warning signs that HPD inspectors document:

• Visible mold growth (any color)
• Musty odors
• Water stains on walls or ceilings
• Peeling paint in moisture-prone areas

These hazardous conditions require immediate attention, as the emergency repair program can step in if you don’t act fast.

How to Stop Mold Before It Starts?

Mold prevention boils down to moisture control. You need systems that catch problems early and fix them immediately.

Start with these non-negotiable steps:

1. Install humidity monitors in problem areas (basements, bathrooms, kitchens)
2. Inspect plumbing quarterly — look for slow leaks under sinks and behind toilets
3. Upgrade ventilation in all bathrooms to code-compliant exhaust fans
4. Respond to water complaints within 24 hours — not the 21 days HPD allows

Create a mold response protocol that your maintenance team can execute:

• Document the moisture source
• Fix the leak or ventilation issue first
• Remove affected materials properly
• Apply antimicrobial treatment
• Repaint with mold-resistant products

3. Heat and Hot Water Failures — The Fastest Path to Emergency Violations

Nothing generates HPD violations faster than heat and hot water requirements violations during heating season. Between October 1st and May 31st, you must maintain:

• 68°F minimum during daytime hours (6 AM – 10 PM)
• 62°F minimum at night
• 120°F hot water year-round

HPD can issue violations within hours of receiving complaints. Worse, they often issue multiple violations — one per affected apartment.

These violations stem from:

• Aging boiler systems
• Thermostat malfunctions
• Inadequate insulation
• Poor heat distribution between floors

How to Maintain Compliant Heat and Hot Water?

Your heating system needs year-round attention, not just emergency repairs when it breaks.

Preventive Maintenance Schedule:

• September — Pre-season boiler inspection and cleaning
• October — Test all apartment temperatures, adjust system balance
• December — Mid-season efficiency check
• March — Identify needed repairs for summer
• June — Complete major repairs when heat isn’t needed

Install remote monitoring systems that alert you when temperatures drop. Modern systems text you before tenants even notice problems.

Keep these supplies on hand for emergencies:

• Portable space heaters (for temporary relief)
• Common boiler parts your system uses
• Contact info for 24/7 boiler repair services

4. Lead-Based Paint — The Violation That Can Shut You Down

Lead hazards carry the heaviest penalties because they affect children’s health permanently. Properties must comply with strict HPD regulations regarding lead paint. HPD can demand extensive remediation work costing tens of thousands per building. Building owners must notify tenants annually about lead paint risks — it’s NYC law.

Properties built before 1960 almost certainly contain lead paint. Even buildings constructed before 1978 require careful management. HPD violations occur when:

• Paint peels, chips, or deteriorates
• Renovation work disturbs lead paint improperly
• Annual inspections aren’t documented
• Tenant notification requirements aren’t met

How to Manage Lead Paint Compliance?

Lead paint compliance requires meticulous documentation and proper procedures. You can’t wing this — HPD demands specific protocols.

Annual Requirements:

• Inspect every unit where children under 6 live
• Provide annual notice to all tenants
• Fix any deteriorating paint using RRP-certified contractors
• Maintain detailed records for 10 years

Smart compliance strategies:

• Encapsulation beats removal for intact paint. Special coatings seal lead paint safely and cost far less than full abatement.
• XRF testing identifies exactly where lead paint exists. Test once, then you know which surfaces need special handling forever.
• Tenant turnover presents the perfect opportunity for lead-safe renovations. Budget for proper lead work during apartment updates.
• Always use EPA RRP-certified contractors for any work that might disturb painted surfaces. Regular contractors can’t legally touch lead paint — and HPD will fine you for using them.

Safety Violations HPD Inspectors Target First

HPD inspectors follow a predictable pattern — they check safety devices before anything else. These violations often come with immediate correction orders and hefty fines because they directly impact tenant survival in emergencies. Master these three areas, and you’ll pass the most critical part of any inspection.

5. Missing or Defective Window Guards — The Child Safety Non-Negotiable

Window guards save lives, period. HPD treats missing or damaged guards as immediate hazards requiring correction within 21 days. The rules are crystal clear for any apartment where children 10 or younger live.

Every window must have approved guards except:

• Fire escape windows (one per apartment)
• First-floor windows
• Windows opening onto balconies/terraces

HPD violations spike for several reasons:

Common failure points that trigger violations:

• Guards installed with gaps larger than 4.5 inches
• Rusted or loose mounting screws
• Tenant-removed guards not replaced
• Wrong guard type for window style
• Missing annual tenant surveys about children

The violation hits harder when inspectors find patterns. One missing guard might get a warning. Multiple apartments missing guards? That’s willful negligence in HPD’s eyes.

How to Maintain Window Guard Compliance?

Window guard compliance starts with proper tenant communication and ends with regular inspections.

Your Annual Window Guard Protocol:

Installation best practices:

• Use approved guards only: Look for the NYC approval stamp. Hardware store guards might seem identical, but they lack proper certification.
• Measure twice, install once: Each window needs guards that fit snugly with no gaps exceeding 4.5 inches anywhere.
• Document everything with photos: Before/after shots prove you fixed violations properly. Date-stamp your photos for bulletproof records.

Create a simple tracking system:

1. Apartment number
2. Number of windows requiring guards
3. Installation date
4. Last inspection date
5. Tenant acknowledgment signature

6. Smoke and Carbon Monoxide Detector Failures

Detector violations rank among the most preventable — yet they account for thousands of HPD citations annually. These devices cost under $50 but save the lives of New Yorkers and prevent massive fines.

HPD requires specific placement and maintenance:

• Smoke detectors within 10 feet of every bedroom
• Carbon monoxide detectors within 15 feet of sleeping areas
• Working batteries are tested annually
• Proper mounting (not sitting on shelves)

Violations multiply fast because inspectors check every single unit. Ten apartments with dead batteries equals ten separate violations.

Why detectors fail HPD inspections:

• Dead or missing batteries
• Detectors past their 10-year expiration
• Improper placement
• Painted-over detectors
• Missing detectors entirely

How to Build a Bulletproof Detector Program?

Smart landlords automate detector compliance rather than racing to fix problems during inspections.

Implement these systems:

• 10-year lithium battery detectors: Such lithium battery detectors eliminate most battery issues. The upfront cost pays for itself by preventing violations and emergency calls.
• Annual testing schedule that tenants can’t skip:
  • Schedule all units for one week
  • Provide a 72-hour notice
  • Test and document each detector
  • Replace any unit over 7 years old
  • Leave door hangers confirming testing
• Quick compliance wins:
  • Buy detectors in bulk for better pricing
  • Standardize on one model for easy replacement
  • Keep 20% spare inventory on-site
  • Train all maintenance staff on proper placement
  • Create photo documentation of each installation

Monthly spot checks catch problems before HPD does. Check 10% of units randomly each month — you’ll identify failing detectors before they become violations.

7. Self-Closing Door Violations — The Fire Safety Requirement

Self-closing doors prevent fire spread, giving tenants crucial escape time. HPD issues immediate Class B violations for non-functioning door closers, requiring correction within 30 days.

These violations affect:

• All apartment entrance doors
• Stairwell doors
• Utility room doors
• Any fire-rated doors
• Common areas like hallways — spaces essential for emergency evacuation

Technical requirements HPD enforces:

• Doors must close fully from the fully open position
• Closing speed between 5-10 seconds
• Latches must engage automatically
• No gaps exceeding ¾ inch

Common self-closer failures:

• Broken spring mechanisms
• Over-adjusted closing speed
• Door frame misalignment
• Tenant-installed door stops
• Paint buildup is preventing closure

How to Keep Self-Closing Doors Compliant?

Self-closing door compliance requires the right hardware and regular adjustments.

Quarterly maintenance checklist:

1. Test every door — open fully and release
2. Time the closing speed — adjust if outside 5-10 seconds
3. Check latch engagement — files may need adjustment
4. Inspect for obstructions — remove any doorstops
5. Document everything — create a door-by-door log

Hardware selection matters. Grade 1 commercial closers last longer and need fewer adjustments than residential models. The extra $30 per door prevents countless violations.

Installation tips that prevent problems:

• Mount closers on the inside of apartment doors
• Use reinforced mounting plates on hollow doors
• Adjust initial closing speed slightly faster — they slow over time
• Apply graphite lubricant quarterly, never WD-40

Proactive replacement strategy:

Track door closer age and replace units before they fail:

• Year 1-3: Quarterly adjustments only
• Year 4-5: Annual mechanism inspection
• Year 6-7: Preemptive replacement during unit turnover
• Year 8+: Replace immediately

Keep these tools on-site for quick fixes:

• Allen wrench set for adjustments
• Replacement arms and brackets
• Graphite lubricant
• Speed adjustment instructions

Pro tip: Create a “door closing map” showing required closing speeds for each door type. Post it in your maintenance room for consistent adjustments across all staff members.

Quick Reference: HPD Violation Compliance Timelines

Staying compliant means tracking multiple deadlines throughout the year. This table consolidates every critical timeline mentioned above for easy reference.

Master Compliance Calendar for NYC Landlords

Keep this timeline handy — missing any deadline can trigger immediate HPD violations and fines.

Steer clear of common mistakes by following these timelines. Some violations are immediately hazardous, while others are non-hazardous but still require prompt attention.

Critical Compliance Reminders

Immediate action triggers that override standard timelines:

• Tenant complaints about heat/hot water — respond within hours
• Water leaks creating mold risk — fix within 24 hours
• Child moves into the unit — install window guards immediately
• Fire department inspection notices — correct before FDNY returns

Documentation requirements across all violations:

• Keep all records for a minimum of 3 years (10 years for lead paint)
• Photograph before/after conditions
• Get tenant signatures on completed work
• File all contractor certificates and licenses

Seasonal peaks when violations spike:

• October-November: Heat complaints surge
• January: Window guard surveys due
• Summer: Pest infestations increase
• September: Pre-heat season prep critical

Use this timeline to build your annual maintenance calendar. Set reminders 30 days before each deadline — giving yourself buffer time prevents last-minute scrambles when HPD shows up.
