1Per the IPMC, who is responsible for enforcing the provisions of the International Property Maintenance Code within a jurisdiction?

A.The owner of the property

B.The code official

C.The local fire marshal

D.The building contractor

Explanation: IPMC Section 103.1 establishes the department of property maintenance inspection, and the code official is charged with the administration and enforcement of the IPMC. The code official has authority to render interpretations and adopt policies and procedures. Exam tip: Know the difference between the code official's authority (enforcement) and the owner's duty (compliance) — IPMC Chapter 1 is heavily tested.

2According to the IPMC, when a notice of violation is issued, what is the minimum information that must be included?

A.Only the owner's name and violation description

B.Description of real estate, statement of violation, corrective action required, and time for compliance

C.Photos of the violation and an estimated repair cost

D.The name of the inspector and the fine amount

Explanation: Per IPMC Section 107.2, the notice of violation must include a description of the real estate sufficient for identification, a statement of the violation with code section cited, a correction order with reasonable time to comply, and a statement of the right to appeal. Exam tip: Memorize the four required elements of a violation notice — this is a classic administration question.

3Per IPMC Section 108, an unsafe structure is one that is found to be dangerous to the life, health, property, or safety of the public or occupants because of which condition?

A.Cosmetic deterioration of interior finishes

B.Lack of structural stability, dilapidation, or not providing minimum safeguards against fire

C.Outdated appliances

D.Non-matching paint colors

Explanation: IPMC Section 108.1.1 defines an unsafe structure as one dangerous because it lacks structural stability, is dilapidated, is damaged, or does not provide minimum safeguards to protect occupants against fire. Such structures shall be condemned per Section 108. Exam tip: Distinguish 'unsafe structure' (108.1.1) from 'unsafe equipment' (108.1.2) and 'structure unfit for human occupancy' (108.1.3) — all three appear on the exam.

4What is the minimum area requirement for every habitable room according to IPMC Section 404.4.1?

A.50 square feet

B.60 square feet

C.70 square feet

D.80 square feet

Explanation: Per IPMC Section 404.4.1, every living room shall contain at least 120 square feet, and every bedroom occupied by one person shall contain at least 70 square feet. Every bedroom occupied by more than one person must contain at least 50 square feet per occupant. Exam tip: Tab Section 404 — minimum room areas and occupancy limits are some of the most frequently tested values.

5According to the IPMC, the minimum ceiling height for a habitable space, hallway, corridor, laundry area, bathroom, toilet room, and habitable basement area is:

A.6 feet 6 inches

B.6 feet 8 inches

C.7 feet

D.7 feet 6 inches

Explanation: IPMC Section 404.3 requires habitable spaces, hallways, corridors, laundry areas, bathrooms, toilet rooms, and habitable basement areas to have a ceiling height of not less than 7 feet. Exceptions allow beams and girders to project to within 6 feet 4 inches of the floor. Exam tip: Remember the 7-foot minimum for the IPMC — the IRC has similar but distinct thresholds, so be careful not to mix up codes.

6The IPMC requires that every habitable space have at least one openable window. The total openable area of the window must be equal to at least what percentage of the floor area of the room for ventilation?

A.2 percent

B.4 percent

C.5 percent

D.8 percent

Explanation: Per IPMC Section 403.1, the minimum openable area to the outdoors shall be 4 percent of the floor area being ventilated. Section 402.1 also requires the minimum glazed area (natural light) to equal not less than 8 percent of the floor area. Exam tip: Memorize the pair — 8 percent glazing for light, 4 percent openable for ventilation — this is one of the most tested IPMC values.

7Per the IPMC, the minimum glazed (window) area for natural light in a habitable room must be not less than what percentage of the floor area?

A.4 percent

B.6 percent

C.8 percent

D.10 percent

Explanation: IPMC Section 402.1 requires every habitable space to have at least one window or skylight facing directly to the outdoors. The minimum total glazed area shall be not less than 8 percent of the floor area. Exception: artificial light providing 6 foot-candles at a 30-inch height may be substituted. Exam tip: The 8-percent light / 4-percent ventilation ratio applies to habitable spaces; bathrooms and kitchens have alternative mechanical provisions.

8What is the minimum required temperature that owners must maintain in habitable spaces during the heating season per the IPMC?

A.65 degrees Fahrenheit

B.68 degrees Fahrenheit

C.70 degrees Fahrenheit

D.72 degrees Fahrenheit

Explanation: IPMC Section 602.3 requires owners of dwelling units and structures who are required to supply heat to maintain a minimum temperature of 68 degrees Fahrenheit (20 C) in all habitable rooms, bathrooms, and toilet rooms during the period from specified dates. Measurements are taken 3 feet above floor level and 2 feet from exterior walls. Exam tip: 68 F is a classic exam value — pair it with the measurement location (3 feet above floor, 2 feet from walls).

9Per IPMC Section 505.1, every dwelling unit shall be supplied with which of the following?

A.Only cold water to a kitchen sink

B.Hot and cold running water to plumbing fixtures in sufficient volume and pressure

C.Hot water only during winter months

D.Potable water for drinking only

Explanation: IPMC Section 505.1 requires every sink, lavatory, bathtub, shower, and laundry facility to be supplied with hot or tempered and cold running water in accordance with the International Plumbing Code. The water service must be connected to an approved public system where available. Exam tip: Know that kitchen sinks require hot and cold, and water closets only require cold water (505.1).

10According to the IPMC, what is the minimum temperature of hot water supplied to plumbing fixtures used for bathing or washing?

A.100 degrees Fahrenheit

B.105 degrees Fahrenheit

C.110 degrees Fahrenheit

D.120 degrees Fahrenheit

Explanation: IPMC Section 505.4 requires the water-heating facilities to be capable of supplying hot or tempered water to every required plumbing fixture at a minimum temperature of 110 degrees Fahrenheit (43 C). This ensures adequate bathing temperature while reducing scald risk. Exam tip: 110 F is the IPMC minimum supply temperature — do not confuse with water-heater setpoints or scald-prevention maximums used in new construction codes.

About the ICC 64 Exam

The ICC Property Maintenance and Housing Inspector (64) exam is administered by the International Code Council and certifies individuals to inspect existing residential and nonresidential structures for compliance with the International Property Maintenance Code (IPMC). The open-book exam tests knowledge of code administration, exterior and interior property conditions, minimum light/ventilation/occupancy requirements, plumbing facilities, mechanical and heating equipment, minimum electrical provisions, and fire and life safety. ICC 64 certification is widely recognized by city, county, and state housing/code enforcement departments and is the industry-standard credential for housing code inspectors.

ICC 64 Study Tips from Top Performers

1Build a reference map from each official outline task to the applicable 2024 IPMC, 2024 IRC, or 2017 Legal Aspects source instead of assuming every question comes from the IPMC

2Follow the official weights: Property Conditions 26% and Administration/Legal 22% are the largest areas, followed by two 14% domains

3For the 2024 IPMC, distinguish the general 70-square-foot habitable-room minimum from more specific occupancy calculations; do not memorize 120 square feet as a blanket minimum

4Verify numerical provisions in the exact selected code cycle and read their exceptions before memorizing a threshold

5Practice timed code lookups — the open-book format only helps if you can find answers quickly. Aim to locate any IPMC section within 30 seconds during practice, and master the distinctions between 'unsafe structure,' 'unsafe equipment,' and 'structure unfit for human occupancy' in Section 108

Frequently Asked Questions

What score do I need to pass the ICC 64 exam?

The ICC 64 exam requires a scaled score of 75. ICC cautions that the scaled score is not the same as a raw percentage or a fixed 38-of-50 count because exam forms can differ. Passing candidates receive PASS rather than a numerical score.

Is the ICC 64 exam open-book?

Yes. The 2024 cycle's official preparation materials identify the 2024 IPMC, 2024 IRC, and Legal Aspects of Code Administration, 2017 edition, as references. Confirm the current exam-catalog list and permitted annotation rules before testing; do not prepare from the IPMC alone.

How hard is the ICC 64 exam?

Open-book does not remove the need to classify the issue and find the governing source quickly. The two largest official areas are Property Conditions at 26% and Administration and Legal at 22%; ICC does not publish a first-time pass rate for this exam.

What codebook do I need for the ICC 64 exam?

For the 2024 code-cycle exam, use the references named in ICC's current catalog and preparation materials: the 2024 IPMC, 2024 IRC, and Legal Aspects of Code Administration (2017). ICC also offers a 2021 exam cycle, so verify the selected code year before purchasing materials.

What is the ICC 64 retake rule?

ICC allows up to six attempts at a national certification exam within a six-month period, with a new fee for each attempt. After the sixth attempt, the candidate must wait until six months have elapsed from the first attempt before registering again.

How do I prepare for the ICC 64 exam?

Start with the official Exam 64 content outline and the exact references for your selected code cycle. Allocate study time by 22/14/14/6/10/8/26, practise identifying which reference governs a scenario, and use timed 50-question open-book drills to build lookup speed.
