1According to Topic 4 of the Iranian National Building Regulations (INBR), what is the minimum required clear floor-to-ceiling height for habitable spaces in residential buildings?

A.2.60 meters

B.2.20 meters

C.2.40 meters

D.2.70 meters

Explanation: INBR Topic 4 (General Building Requirements) establishes that all primary habitable spaces in residential buildings—such as living rooms, bedrooms, and dining spaces—must maintain a minimum clear finished floor-to-ceiling height of 2.40 meters. Secondary spaces such as corridors, bathrooms, and storage rooms are permitted a reduced clearance of 2.10 meters.

2INBR Topic 4 fixes a minimum tread depth for stairs and also requires that 2 x riser + tread fall between 63 and 64 cm. Taken together, what maximum riser height do these two rules allow on a common (shared) residential staircase?

A.Minimum tread of 25 cm, giving a maximum riser of about 20 cm

B.Minimum tread of 30 cm, giving a maximum riser of about 17 cm

C.Minimum tread of 22 cm, giving a maximum riser of about 21 cm

D.Minimum tread of 28 cm, giving a maximum riser of about 18 cm

Explanation: INBR Topic 4 sets the minimum useful tread depth (kaf-e pelleh) at 0.28 m and requires that twice the riser plus the tread lie between 0.63 and 0.64 m. Substituting the minimum tread: 2h = 64 - 28 = 36 cm, so h = 18 cm at the upper bound (and 17.5 cm at the 63 cm bound). The proportioning rule and the minimum tread therefore cap a shared residential stair at roughly an 18 cm riser.

3Using the standard ergonomic formula mandated in INBR Topic 4 (2 × Riser + Tread = 63 to 64 cm), if an architect specifies a riser height of 17.5 cm for a public residential staircase, what is the acceptable range for the tread depth?

A.26.0 cm to 27.0 cm

B.28.0 cm to 29.0 cm

C.30.0 cm to 31.0 cm

D.32.0 cm to 33.0 cm

Explanation: Applying the formula 2h + b = 63 to 64 cm: 2 × 17.5 cm = 35.0 cm. Subtracting this from 63 cm yields b = 28.0 cm, and subtracting from 64 cm yields b = 29.0 cm. Both values satisfy the minimum required public tread depth of 28 cm under INBR Topic 4.

4Under INBR Topic 4, what is the minimum useful (clear) width of a corridor that forms part of a building's main access route?

A.1.40 meters

B.1.10 meters

C.1.20 meters

D.0.90 meters

Explanation: INBR Topic 4 requires corridors on the main access route to have a minimum useful width of 1.40 meters. Topic 4 allows this to drop, as far as 0.90 meters, only in its defined exceptional cases, such as a low occupant load or a route on which accessible access is not required. Inside an individual dwelling unit the minimum corridor width is 0.90 meters.

5When designing a light well (pasio) to provide natural light and ventilation for primary habitable rooms (such as bedrooms or living rooms) in buildings up to 5 stories high, what is the minimum required horizontal area according to INBR Topic 4?

A.4 square meters with a minimum dimension of 1.5 meters

B.9 square meters with a minimum dimension of 2.5 meters

C.6 square meters with a minimum dimension of 2.0 meters

D.12 square meters with a minimum dimension of 3.0 meters

Explanation: INBR Topic 4 mandates that when a light court (pasio) illuminates primary habitable spaces (living rooms and bedrooms) in buildings up to 5 stories, its horizontal clear surface area must be at least 12 square meters, with no horizontal dimension less than 3.0 meters. For secondary spaces like kitchens, the minimum area is 6 square meters with a minimum dimension of 2.0 meters.

6What is the minimum horizontal clear floor area and minimum width required for a kitchen providing ventilation and light via a light court in a multi-story residential building under INBR Topic 4?

A.6.0 square meters area with a minimum clear width of 2.0 meters

B.5.0 square meters area with a minimum clear width of 1.6 meters

C.5.5 square meters area with a minimum clear width of 1.8 meters

D.4.5 square meters area with a minimum clear width of 1.5 meters

Explanation: INBR Topic 4's rules for cooking spaces and kitchens set a minimum floor area of 5.5 square meters and a minimum clear width of 1.80 meters between finished wall faces, plus unobstructed working space in front of the counter run. An independent (closed) kitchen must also receive natural light; open and wall-type kitchens may rely on artificial light with mandatory mechanical extraction.

7Under INBR Topic 4, what is the minimum required height for protective balustrades or guardrails on open residential balconies, roof terraces, and stair landings?

A.1.00 meter

B.0.90 meters

C.1.10 meters

D.1.20 meters

Explanation: INBR Topic 4 requires that guardrails and balustrades on elevated walking surfaces, exterior balconies, roof terraces, and stair landings must have a minimum finished vertical height of 1.10 meters. For internal staircases, handrails are typically set at 0.90 meters, but outer edge perimeter fall-protection must meet the 1.10-meter standard.

8According to INBR Topic 4, vertical balusters on exterior balconies and open stair guardrails must be spaced such that which of the following objects cannot pass through?

A.A sphere with a diameter of 12 cm

B.A sphere with a diameter of 10 cm

C.A sphere with a diameter of 15 cm

D.A sphere with a diameter of 11 cm

Explanation: INBR Topic 4 specifies that openings in protective railings and balustrades must not allow the passage of a sphere with a diameter of 11 cm (110 mm) to prevent infants and small children from slipping through or becoming trapped.

9What is the minimum clear width of an entry door serving a single-family residential unit (apartment entrance door) under INBR Topic 4?

A.0.80 meters

B.0.90 meters

C.1.00 meter

D.0.75 meters

Explanation: INBR Topic 4 requires apartment unit main entrance doors to have a minimum clear opening width of 0.90 meters (allowing convenient entry, furniture moving, and emergency access). Internal bedroom doors require a minimum of 0.80 meters, and bathroom doors require 0.70 meters.

10In multi-story residential buildings, what is the minimum required width of a common public stair flight under INBR Topic 4?

A.1.20 meters

B.0.90 meters

C.1.10 meters

D.1.40 meters

Explanation: Under INBR Topic 4, common public stairs in multi-family residential buildings serving more than two dwelling units must maintain a minimum clear width of 1.10 meters between finished walls or between a wall and a handrail. In buildings with more than 50 occupants, wider flights may be required by egress load calculations.

Frequently Asked Questions

What is the format of the official Iran Nezam Architecture Design exam?

Clause 6-1 of the official 1405 registration instruction states that all Nezam Mohandesi entry-to-profession exams are four-option multiple choice except architecture-design, which is held as a drawing-based (tarsimi) paper lasting roughly 7 to 8 hours. Candidates are given a site lot with specific zoning parameters, street alignments, and floor area ratios, and must draw complete architectural plans including basement parking, ground floor access, typical residential levels, building sections, and egress details. This is an independent English-language MCQ study adaptation by OpenExamPrep covering the underlying technical codes, dimensions, and regulatory calculations — it is not an official translation and does not simulate the drawing paper.

What are the eligibility requirements for the Nezam Architecture Design exam?

Candidates must hold an accredited degree in Architecture approved by the Ministry of Science, Research and Technology. Eligibility requires a minimum post-graduation practical work period: 3 years for Bachelor's degree (Karshenasi) holders, 2 years for Master's degree (Karshenasi Arshad) holders, or 1 year for Ph.D. (Doctora) holders.

What is the passing score for the Architecture Design exam?

Clause 6-4 of the official 1405 registration instruction sets the pass threshold at 50 out of 100 (50%) for every Nezam Mohandesi discipline and competency, including architecture-design. There is no conditional pass: candidates who miss the threshold simply re-sit in a later round. Evaluation is nonetheless demanding, because serious design errors such as failing to provide required parking stalls, creating unventilated habitable rooms, or violating fire egress rules weigh heavily on the marked drawing.

Is the Architecture Design exam open book?

Yes. Clause 6-2 of the official 1405 registration instruction states that the entry-to-profession exams in all disciplines are held open book (ketab baz); only the Article 27 expert-assessment exam is closed book. Candidates may bring official copies of the National Building Regulations (Mabahes), municipal zoning codes, and drafting guides into the examination hall, alongside manual drafting equipment.

Which National Building Regulations (INBR) are tested in Architecture Design?

The primary tested regulations include Topic 3 (Protection of Buildings Against Fire), Topic 4 (General Building Requirements), Topic 15 (Elevators and Escalators), Topic 18 (Acoustic Insulation and Sound Attenuation), Topic 19 (Energy Conservation in Buildings), and the Urban and Architectural Regulations for Persons with Physical Disabilities.
