311, HPD, HP action, or a lawyer's letter: which one gets the repair done?

NYC HOUSING MAINTENANCE CODE · RPL § 235-b

Tool one: the 311 complaint and the HPD violation.

Call 311 or file online, and the Department of Housing Preservation and Development schedules an inspection. If the inspector confirms the condition, HPD issues a violation against the building and the owner. Violations are classified by severity, and the class determines the landlord's legal deadline to correct:

• Class A, non-hazardous: minor conditions such as a small area of peeling non-lead paint or a missing sign. The correction period is the longest, measured in months.
• Class B, hazardous: conditions such as a leaky faucet that has caused damage, a broken window guard, a defective door lock, or moderate mold. The correction period is about a month.
• Class C, immediately hazardous: no heat, no hot water, rodents, lead paint hazards where a young child lives, extensive mold, and similar. The correction period is the shortest: roughly three weeks for most Class C conditions and as little as 24 hours for heat and hot water.

The violation is posted on HPD's public building information system. It follows the building through sales and refinancing, affects the owner's standing in city programs, and can support civil penalties that HPD pursues in Housing Court. For immediately hazardous conditions the landlord will not fix, HPD's emergency repair program can send a contractor and bill the owner.

What a complaint cannot do: pay you. HPD enforces the code on behalf of the City; it does not award you a rent abatement or reimburse you for the space heater. It also cannot, by itself, force a specific repair on a specific day. A violation is leverage and evidence, not a remedy in your pocket.

Tool two: the HP action in Housing Court.

An HP action, short for Housing Part proceeding, is a case a tenant brings against the landlord (and HPD is joined as a party) in the Housing Part of the New York City Civil Court, asking a judge to order repairs. It is one of the most tenant-accessible proceedings in the state. The filing fee is modest, and tenants who cannot afford it can apply for a fee waiver by submitting a short affidavit of financial hardship. The Housing Court clerk's office provides the forms, and tenants regularly file without a lawyer.

After filing, the court orders an HPD inspection of the conditions you listed, sets a return date, and typically presses the parties toward a consent order: a signed agreement in which the landlord commits to specific repairs by specific dates, with access dates built in. If the landlord does not comply, you return to court and the judge can impose civil penalties and, in egregious cases, contempt. HP actions can also be brought for harassment under the Housing Maintenance Code, which carries its own penalties.

What an HP action cannot do well: it is focused on repairs, not money. A court in an HP proceeding will order the work and may impose penalties payable to the City, but a rent abatement is generally claimed separately, either as a counterclaim when the landlord sues for rent or in an affirmative case in Civil Court or small claims. And it takes time: several court dates over weeks or months, each requiring you to appear.

Tool three: the attorney demand letter.

A demand letter from a New York attorney does what neither a complaint nor an HP action is designed for: it names a number and a deadline and delivers them to a decision-maker. The letter recites your written notice history, lists the HPD complaint and violation numbers, cites Real Property Law § 235-b and the Housing Maintenance Code provisions at issue, states the rent abatement owed for the period already elapsed, and demands repair plus a rent credit by a date certain, failing which the tenant will file an HP action and pursue the abatement in court.

It works because it changes who is reading. A 311 complaint is handled by an HPD inspector; your email to management is handled by whoever checks that inbox. A letter from counsel is forwarded to the owner or the landlord's attorney, and that person can evaluate a documented claim and authorize a credit. Rational landlords settle documented claims because defending them costs more than resolving them. The complete picture of how our letters work is at flat-fee demand letters; the repairs-specific letter is at DemandLetterNY.

What a letter cannot do: it cannot inspect the apartment, it cannot order anyone to do anything, and it will not warm a cold apartment tonight. A letter with no violation and no notice history behind it is also a weak letter; the record is what gives it force.

Which one fits which situation.

• Emergency, right now (no heat in January, sewage, active electrical hazard): 311 first, today. Ask about emergency repair. A letter and the abatement claim follow once the immediate danger is handled. See no heat or hot water in NYC.
• Chronic condition the landlord keeps promising to fix (a leak that returns, mold that gets painted over, intermittent heat): 311 each time it recurs, to build the violation history; then a demand letter for repair and abatement once you have two or three violations and a notice chain. See mold and leaks.
• Landlord ignoring open violations past the correction deadline: HP action, with a demand letter either before filing (to offer a last chance to settle) or alongside it (to put the abatement claim on the table while the court handles the repair).
• Condition is fixed, but you want your money back for the bad months: demand letter for the abatement; small claims if refused. The letter frequently settles it. See rent abatement and demand letter vs. small claims.
• Absentee or insolvent owner, building-wide collapse of services: HP action or, with a third of the tenants, a 7-A proceeding to have an administrator appointed. A letter to an owner who has abandoned the building is not the priority.

Why tenants usually do both.

The HPD complaint and the demand letter are complementary, not redundant. The complaint creates the independent, official record of the condition that no landlord can dispute and no judge will discount. The letter takes that record and converts it into a specific demand with a deadline and a dollar figure. A letter that cites three open Class C violations is a different document from a letter that cites the tenant's own say-so; a violation with no follow-up demand tends to sit on HPD's website while the landlord pays a fine and does nothing for you.

A sequence that works in most chronic-repair cases: written notice to the landlord; 311 complaint and inspection; second written notice referencing the violation; demand letter for repair and abatement with a two-week deadline; HP action and abatement claim if the deadline passes. Each step makes the next one stronger, and many cases never reach the last one.

Two cautions.

First, do not withhold rent as your strategy. Withholding converts you from the tenant with a claim into the respondent in a nonpayment case, where you will likely have to deposit the rent with the court and where the landlord controls the timing. The habitability defense is real, but it is a defense; pursue the claim affirmatively while you keep paying. If you must withhold, escrow every dollar yourself and talk to a lawyer first.

Second, do not fear the complaint. Real Property Law § 223-b prohibits retaliation for good-faith complaints to government agencies and for enforcing the warranty of habitability, with a presumption of retaliation for adverse action within a year, outside small owner-occupied buildings. A 311 history is protected activity, and an attorney letter will put the landlord on notice of that at the same time it demands the repair.
