This guide covers the New York City High Pressure Boiler Operating Engineer route end to end: a city license with no state counterpart, the seven published experience routes and their New York City time requirements, the written examination’s 110 questions across Administration, Inspection and Testing, Operation and Maintenance, and Repairs and Alterations, the practical examination that follows it, the Department’s $525 written and $350 practical fees, and the deadlines – six months to sit, two months to apply for the practical, twenty-four months to pass it – that govern the sequence.

The licensing route at a glance
| Item | Verified position |
|---|---|
| License in this program | High Pressure Boiler Operating Engineer License (stationary and portable), issued by the New York City Department of Buildings under Title 28 of the New York City Administrative Code. This is a New York City license; New York State issues no boiler operator license |
| License structure | The license has TWO examinations: a written examination and a practical examination. PassProfessor preparation covers the WRITTEN examination only. The practical examination – 15 exercises in 90 minutes, 70 percent to pass with critical exercises that must be passed – is a Department requirement outside this program’s scope |
| Written examination | 110 multiple-choice questions, closed book, 4 hours, administered by CPS HR Consulting for the Department of Buildings and delivered at Pearson VUE testing locations. Passing score: 77 correct answers (70 percent) |
| Written examination outline | Administration – 22 questions; Inspection and Testing – 33; Operation and Maintenance – 33; Repairs and Alterations – 22 |
| Qualifications | At least 18 years old; able to read and write English; good moral character; fit to perform the work; and one of the experience routes in the Department’s published guide |
| Experience routes (any one) | Five years within the last seven under a licensed high pressure boiler operating engineer in New York City; OR a bachelor’s degree in mechanical engineering plus one year within the last two under a Department-licensed engineer in the City; OR an engineer or U.S. Coast Guard marine engineer certificate held four years plus one year in the City within the last seven; OR five years in direct supervision of a governmental building steam plant with boilers of at least 150 horsepower plus one year in the City within the last seven; OR a registered apprenticeship of at least two years plus three years within the last seven; OR a National Board commission held seven years plus five years of high-pressure experience within the last seven; OR a high-pressure operating engineer license or certification from another ASME-code jurisdiction held five years with employment during five of the last seven years |
| Sequence and deadlines | Apply for the written examination first; the examination must be taken within six months of application approval. The practical application is due within two months after passing the written examination, and the practical must be passed within 24 months of the written pass notification |
| Department fees | New York City Department of Buildings fees, payable by money order only: written examination $525; practical examination $350. Background investigation and license issuance fees are separate and are not included in those figures |
| Renewal | The license is renewed every three years (New York City 311) |
Three disciplines govern this route: take the written examination within six months of application approval; apply for the practical within two months of passing the written; pass the practical within twenty-four months of the written pass notification. Fees are the Department’s, paid by money order: $525 written, $350 practical, with background investigation and license issuance fees additional and not printed in the Department’s guide – this guide prints no figure for them rather than guess. And one scope line belongs at the front: this guide prepares candidates for the written examination; the practical is described for route planning only.
The licensing route, step by step
Step 1 – Establish your route and your standing
Confirm the personal qualifications – 18 or older, English literacy, good moral character, fitness for the work – and match your history to one of the seven published experience routes, noting how much of your qualifying time is inside New York City and inside the route’s lookback window. If no route fits yet, the apprenticeship road and the under-a-licensee road are the system’s designed entries.
Step 2 – Apply for the written examination
File the written examination application with the Department of Buildings. Background investigation is part of this licensure; the examination fee of $525 is payable by money order. Once approved, the sitting must occur within six months.
Step 3 – Sit and pass the written examination
Sit at a Pearson VUE location under the CPS-administered programme: 110 multiple-choice questions, closed book, four hours, 77 correct to pass. Results are issued by the Department’s process; a pass starts the practical clocks.
Step 4 – Apply for and pass the practical
File the practical application within two months of passing the written, pay the $350 practical fee by money order, and pass the practical – 15 exercises, 90 minutes, 70 percent with critical exercises mandatory – within 24 months of the written pass notification.
Step 5 – Licensure and renewal
With both examinations passed and the issuance steps completed, the Department issues the license, stationary and portable in scope. Renewal runs on a three-year cycle.
The Administration domain: the fifth of the paper candidates skip
Administration carries 22 of 110 questions – as many as Repairs and Alterations – and it examines the license’s legal skeleton: the Administrative Code’s licensing and filing duties, the City rules on boiler inspections and annual filings, the operating certificate regime, and the State Labor Department’s Part 14 rules for high-pressure boilers. Operators experience this material as the paperwork around the real work, and the examination treats it as a fifth of the real work.
The study consequence is direct: a candidate cannot reach 77 on operation and inspection strength alone while conceding administration. Read Title 28’s boiler provisions and the cited rules as examination text, learn the filing and inspection calendar as procedure rather than trivia, and mark administration items in practice with the same seriousness as a low-water cutoff question – the paper already has.
Inspection and Testing, Operation and Maintenance: the twin 33s
Sixty-six of the 110 questions sit in two domains. Inspection and Testing examines the regulated life of the vessel: inspection types and intervals, testing regimes, the condition assessment of boilers and their appurtenances, and the City and State rules that schedule them. Operation and Maintenance examines the working plant: firing, feedwater, water treatment, auxiliaries, controls and safety devices, and the maintenance practice that keeps a high-pressure plant inside its inspection envelope.
The domains reward different study. Inspection and Testing is rule-anchored – its answers live in the codes and rules on the reference list. Operation and Maintenance is craft-anchored – its answers live in steam plant operation as the standard texts teach it, disciplined by City practice. A preparation that treats both as ‘boiler questions’ misses that one is a memory-of-rules exercise and the other a judgment-of-practice exercise, and that the closed book tests each without its usual aids.
Repairs and Alterations: the controlled fifth
Repairs and Alterations, 22 questions, examines the most procedurally guarded work in the plant: what may be repaired, by whom, under what approvals, with what testing and documentation before a vessel returns to service. The domain’s centre of gravity is authorisation – the boundary between the operating engineer’s maintenance authority and the work that belongs to licensed repair organisations, inspectors, and Department filings.
Candidates with strong plant backgrounds should note the trap this domain sets for them: experience teaches what is done; the examination asks what is permitted, by whom, and with what paper. Study the domain from the code outward, and let plant habit answer only after the rule has.
The reference list as syllabus
The candidate bulletin’s reference list is the most underused document in this licensure. It names the law (Title 28; Mechanical Code Chapters 10 and 12; 1 RCNY Sections 20, 22, and 103-05; State Part 14) and the craft texts (Steam Plant Operation; High Pressure Boilers), and the outline’s weights can be mapped onto it: administration and inspection draw on the law; operation and repairs draw on both. A preparation organised by the reference list – each source read for the domains it feeds – covers the paper by construction. A preparation organised by habit covers the paper by accident.
The practical, planned for and not prepared here
This guide does not prepare candidates for the practical examination, and this section exists so the omission is a plan rather than a surprise. The practical is 15 exercises in 90 minutes, passed at 70 percent with critical exercises that must be passed individually; it is administered by the Department’s programme following the written pass. Its preparation is supervised plant practice under licensees who know its exercise families – the same community the experience routes already require candidates to work within.
Plan the practical from the day the written application is filed: identify where your exercises will be practised, keep the two-month application deadline and the 24-month completion deadline on the same calendar as the written date, and treat a written pass as the start of the campaign’s second half, not its end. Candidates have lost this license to an expired 24 months more quietly than to any question on the paper.
Fees and the money-order discipline
The Department’s examination fees are $525 for the written and $350 for the practical, payable by money order only, and they exclude background investigation and license issuance fees. The money-order-only rule is a small fact with planning weight: payment logistics belong in the application checklist, not the week of the deadline. Total-route budgeting should carry the two examination fees, the additional issuance-side fees the Department assesses (whose amounts are confirmed in the Department’s current application materials), and triennial renewal.
Retakes and appeals in the City system
The candidate bulletin publishes the examination programme’s notification and retake mechanics, including the process by which a failing candidate re-enters the schedule and the window inside which results may be queried. Candidates should read the current bulletin for those terms at the time they apply, because they are programme terms rather than statute, and they change with the programme. The structural point survives any bulletin edition: re-entry consumes calendar inside the same six-month and twenty-four-month clocks’ logic, so a failed first sitting is a scheduling event as well as a study event.
The City license among American operator credentials
No state issues this license’s counterpart at its scale: a municipal license, earned through city-specific experience routes, examining city law at a fifth of the paper, and gating with a practical. Operators arriving from state systems should expect the portability to run one way – the other-jurisdiction route imports their licenses into candidacy here, but the City’s license itself answers to New York’s market. Inside that market it is the defining credential for high-pressure plant, held by the engineers of the institutions that anchor the city’s building stock.
The State layer: Part 14 inside a City license
The written examination’s reference list contains a document candidates from other systems find surprising: the New York State Department of Labor’s Part 14 rules, the State’s high-pressure boiler rules, sitting alongside the City’s Administrative Code and Mechanical Code. The layering is real rather than decorative. The City licenses the operator and administers its own construction codes; the State’s boiler rules govern the high-pressure vessels themselves within the State’s industrial code framework, and a City plant answers to both. The examination therefore tests a two-layer competence: the City’s licensing, filing, and inspection duties, and the State rules for the equipment operated.
For preparation, the consequence is that Part 14 is not background reading but examination text, weighted through the Inspection and Testing and Administration domains. Candidates whose plant experience is entirely City-side should still study the State rules as written, and candidates arriving from upstate New York industry – where Part 14 applied without any City license at all – should note the inversion: their equipment rules travel with them, and the City’s operator license is the new layer they lack.
Good moral character, fitness, and the background investigation
The Department’s qualifications for this license include two clauses that examinations cannot test and applications decide: the applicant must be of good moral character, and fit to perform the work of the license. Around them sits the Department’s background investigation, a step the license guide separates from the examination fees and treats as part of the licensure itself. The design reflects the license’s trust position: a high pressure boiler operating engineer holds unsupervised charge of plant inside occupied buildings – hospitals, residences, schools – and the City investigates the person as well as examining the knowledge.
Candidates should treat the application as a whole-document exercise: the experience route’s dates and employers stated exactly as records will show them, the qualification clauses answered plainly, and no discrepancy left for the investigation to find first. In a system with seven experience routes and lookback windows of two and seven years, precision in the application is itself a qualification signal – and imprecision the most avoidable cause of delay in the entire route.
Stationary and portable: the license’s two fields
The license’s full name in the Administrative Code family is the high pressure boiler operating engineer licence for stationary and portable service, and the portable half is easy for building-based candidates to undervalue. Stationary plant is the familiar field – the fixed boiler rooms of the City’s buildings and institutions. Portable plant is the City’s moving steam: temporary boilers during plant replacement and construction, rental and emergency units, and the steam supply of a building stock that is perpetually being rebuilt around its occupants. The same license commands both, and the written examination’s Operation and Maintenance and Repairs domains sample the judgement both fields share.
The portable field changes the engineer’s working conditions in ways the examination respects: unfamiliar plant accepted on inspection and documentation rather than history, temporary piping and connections, compressed commissioning, and the discipline of walking away from a safe plant rather than a familiar one. Candidates whose experience is entirely stationary should not treat the portable scope as a footnote in their license’s title – it is half the title, and the Department issues one license for both fields because the standard of care is the same in each.
Four hours and 110 questions: pacing the written paper
The written examination’s arithmetic is severe enough to deserve its own plan: 110 questions in 240 minutes is a little over two minutes a question, sustained for four hours, closed book. Pacing is therefore not a test-day tactic but a preparation target. Candidates should build, in practice, a personal rhythm – a first pass that banks the certain answers across all four domains, a second pass that works the deliberation items, and a reserve for the questions that require calculation or code recall – and should know, from timed rehearsal, what their own two-minute item feels like. The domain weights give the rhythm its map: with Inspection and Testing and Operation and Maintenance at 33 questions each, a candidate can spend half the sitting inside those two domains without imbalance, while Administration’s 22 must be neither rushed as an afterthought nor allowed to consume operation time.
Stamina is the second variable. A four-hour closed-book sitting degrades recall in its final hour for unrehearsed candidates, and the degradation lands on whichever domain the candidate reaches last. Full-length timed rehearsals – at the sitting’s length, with its break discipline – are the only honest preparation for that hour. The 77-answer line, finally, should be tracked in practice by domain: the passing candidate is not the one with a brilliant domain but the one whose weakest domain still contributes its share of the 77.
The result letter and what starts when it arrives
In most systems the pass notice is the end of the examination story; in this one it is a starting gun. The written pass notification opens the twenty-four-month window inside which the practical must be passed, and the two-month practical application deadline runs from the same event. Candidates should therefore prepare the practical application’s logistics before the written result arrives – the fee’s money order, the application’s forms, the practice arrangements for the exercises – so that the notification converts into filings within days rather than weeks. The twenty-four months feel long and behave short: they contain work, seasons, and the practical’s own scheduling, and the candidates who lose licenses to this window are almost never the ones who failed anything. They are the ones who treated a clock as a cushion.
The same letter, read from the other side, is the route’s best planning document: it fixes the date from which both deadlines run, and a candidate who calendars the two-month and twenty-four-month marks on the day the letter arrives has converted the license’s most dangerous interval into two appointments. Keep the notification itself with the application file – dates in this licensure are proven from documents, and the pass notice is the document both clocks cite. Filed promptly, the practical application also buys scheduling choice: the candidate who applies inside the first weeks chooses among sittings, while the candidate who files at the deadline takes what remains.
A written-examination preparation plan
Organise preparation by the outline’s weights and the reference list’s sources. Give administration a scheduled fifth of study time from the first week, not the last. Alternate rule-reading (Title 28, the Mechanical Code chapters, the cited rules, Part 14) with craft study from the named texts, and practise closed book and timed in four-hour blocks as the sitting approaches – stamina across 110 questions is itself examined. Track practice by domain against the 77 line: the target is not a strong domain but no weak one.

Frequently asked questions
Why is there no New York State program page?
Because there is no New York State boiler operator license to prepare for. Boiler operator licensure in New York exists at the City level; this guide covers the City license only.
What is Title 28’s role in this license?
Title 28 of the New York City Administrative Code contains the construction-code licensing framework under which the Department of Buildings issues the High Pressure Boiler Operating Engineer License, including Section 28-412.1 for this license class.
What are the critical exercises on the practical?
The candidate bulletin states that the practical examination includes critical exercises that must be passed for the candidate to pass overall, within its 15 exercises in 90 minutes at a 70 percent standard. This guide covers the written examination; the practical is described for route planning only.
Can a Coast Guard marine engineer qualify?
Yes – one published route accepts an engineer certificate or a U.S. Coast Guard marine engineer certificate held for four years, plus one year of experience in New York City within the last seven years, per the Department’s guide.
How long is the license valid?
The license renews every three years, per New York City 311.
What happens if the six months to sit expire?
The Department’s guide requires the written examination to be taken within six months of application approval; a candidate who lets the window lapse must re-enter the application process under the Department’s current terms.
Are calculators allowed on the written examination?
The candidate bulletin permits scratch paper and, under its stated terms, a silent non-programmable calculator. Confirm the current bulletin’s terms when you schedule.
Does the written examination include the State’s rules as well as the City’s?
Yes. The bulletin’s reference list includes the New York State Department of Labor’s Part 14 rules for high-pressure boilers alongside the City’s Administrative Code, Mechanical Code, and City rules.
What is the Administration domain really testing?
The legal operating envelope of a City plant: licensing duties, inspections and annual filings under the City rules, operating certificates, and the administrative obligations the Administrative Code places on the engineer of record.
Where do this guide’s facts come from?
From the Department of Buildings’ license guide and the Department/CPS HR Consulting candidate bulletin, with the renewal cycle from New York City 311, recorded in this file’s INTERNAL section. The written examination facts are the bulletin’s; the route and fee facts are the Department guide’s.
