CBSE School Building Norms for Delhi in 2026: Land, Classroom and Lab Sizes, Sections per Built-Up Area, and the Building Rules on Top

A CBSE school in Delhi has to satisfy two sets of rules at once. The board's affiliation bye-laws decide how much land it needs, the minimum size of its classrooms, labs and library and, since an amendment in July 2025, how many sections it may run for the built-up area it has. Delhi's building bye-laws and master plan decide how the building itself is built: room heights, staircases, corridors, toilets, accessibility, ground coverage, FAR and height. The short version for Delhi: at least 1,600 sqm of land for a school up to the secondary level and 2,400 sqm up to senior secondary; classrooms of at least 8 m by 6 m and science labs of 9 m by 6 m; and 1,800 sqm of certified built-up area for 15 sections at senior secondary level, with 3 more sections for every further 400 sqm. This guide sets out each rule with its source, what changed in 2025 and 2026, and what it means for a school planning a new block.

How Much Land Does a CBSE School Need in Delhi?

Since January 2026, 1,600 sqm up to the secondary level and 2,400 sqm up to senior secondary. Circular 04/2026, dated 19 January 2026, replaced clauses 3.3 to 3.7 of the Affiliation Bye-Laws 2018 with a three-category table: 6,000 sqm anywhere in the country (category A); 2,400 and 3,200 sqm within 'Y' category cities, state capitals and hilly areas (B); and 1,600 and 2,400 sqm within the municipal limits of 'X' category cities notified by the Finance Ministry's order of 7 July 2017, and in Arunachal Pradesh, Sikkim and the island territories (C). That order lists 'Delhi (UA)' among the X cities, which puts Delhi schools in category C. The circular also asks every school for a play area of at least 2,000 sqm within the campus; a school on less than 6,000 sqm may instead show an arrangement of at least 15 years with a nearby school, college, stadium, sports complex or public park within 200 m, reached without crossing a highway or a major road carrying heavy traffic. It leaves the covered area and height of the building to 'notified Building Bye Laws of the respective State/UT', which in Delhi means the rules further down this guide. The board's current SARAS manual, version 7.0 in effect from 26 February 2026, specifies the boundary wall as concrete and at least 6 ft high, without grills, mesh or gaps below that height, and says 'the use of basement in school for any kind of academic or sports activities is not allowed'.

What Size Must Classrooms, Labs and the Library Be?

Chapter 4 of the bye-laws sets the minimums: classrooms of 8 m by 6 m, about 500 sq ft, one room for each class, with at least 1 sqm of floor space per student (clause 4.1); science laboratories of 9 m by 6 m each, a composite lab for secondary and separate physics, chemistry and biology labs for senior secondary (4.2); a library of 14 m by 8 m with a reading room (4.3.1); a computer lab of 9 m by 6 m (4.4); a mathematics lab at least the size of a classroom (4.5); and either separate rooms for music, dance, arts and sports or one multipurpose hall (4.6). Clause 4.8 puts the optimum at 40 students a section and calls one square metre of built-up floor area per child in the classrooms 'an absolute necessity'. Toilets and drinking water are required on each floor, with separate toilets for boys, girls, primary students and staff (4.7.1 and 4.7.2). A July 2025 amendment to Chapter 4 raised the computer lab to at least 40 computers at a ratio of 1:18, with one lab for every 720 students, and a July 2025 safety amendment added clause 4.7.10: CCTV cameras at entry and exit points, lobbies, corridors, staircases, classrooms, labs, the library and other common areas except toilets, with at least 15 days of footage stored.

The July 2025 Appendix V circular restates the minimum academic infrastructure for up to 48 sections in square metres: a 112 sqm library; 54 sqm each for the composite science, physics, chemistry, biology and computer labs; a 48 sqm maths lab; four 54 sqm activity rooms or one 216 sqm hall; and a 48 sqm infirmary or wellness room, with a further set to be created beyond every 48 sections. And since March 2026 the list has a new room: Circular Skill-13/2026 calls for a Composite Skill Lab of 600 sq ft for classes VI to XII, or two labs of 400 sq ft each, mandatory for fresh affiliation, with schools already affiliated to have one by 22 August 2027.

How Many Sections Can a School Run for Its Built-Up Area?

Since July 2025, the answer comes from the building, not the land. The Appendix V circular says 'the maximum number of sections to be permitted as per amended Appendix-V shall be based on the total built-up carpet area of the school building', applies the rule to 'all the existing and newly affiliated schools', and uses land area only to decide the school's category. Circular 06/2026 of 25 February 2026 then clarified that 'carpet area' is to be read as 'Built-up Area', certified by the local body or a licensed architect in a prescribed format that leaves out basements. The table starts at 1,000 sqm, the minimum for a branch school, with 8 sections; 1,400 sqm, the minimum for middle and secondary level, allows 13; 1,800 sqm, the minimum for senior secondary, allows 15; and from there every further 400 sqm adds 3 sections (2,200 sqm: 18; 3,000 sqm: 24; 4,200 sqm: 33; 5,400 sqm: 42; 6,200 sqm: 48), with '03 sections for every 400 sq. mtrs.' beyond the table. The sections in classes IX and X, and in XI and XII, are each capped at one quarter of all sections running from Bal Vatika to class X or XII, rounded up to the next even number, with equal sections in IX and X and in XI and XII. For a managing committee the practical reading is simple: every extra 400 sqm of certified built-up area is worth 3 sections, which makes a new block the route to more admissions.

Which Certificates Does CBSE Ask For?

Seven essential certificates under Circular 12/2022, without which an application 'shall be rejected summarily'. Three of them rest on the building. The Building Safety Certificate is issued, in the SARAS manual's current wording, by 'an officer not below the rank of an Assistant Engineer of the Government works department', or, where the local body has empanelled engineers, by 'such empaneled Structural Safety Engineer'. The Fire Safety Certificate comes from the government fire service. The water and sanitation certificate comes from the public health engineering department or the local body. The manual adds that the certificates must remain valid while the school functions. Our school building safety certificate guide explains who signs what and the repairs that precede the signature, and our Fire NOC guide covers the fire rules; under the Delhi Fire Service rules reproduced in the bye-laws, an educational building more than 9 m high, or of ground plus two upper storeys including a mezzanine, needs fire clearance.

What Do Delhi's Building Bye-Laws Add?

CBSE's norms sit on top of the local rules, and in Delhi those are the Unified Building Bye-Laws 2016. Clause 7.23.2 deals with educational buildings directly. A room used for instruction must be at least 5.5 m by 4.5 m, smaller than CBSE's 8 m by 6 m, so a CBSE school designs to the board's size; no part of it may be more than 7.5 m from an external wall on the required open space, and its ventilation openings must be at least a fifth of its floor area. At least 1.0 sqm of net floor space is required per student. Classrooms need a minimum room height of 3.6 m, with at least 3 m of headroom under beams, and assembly rooms a clear height of 3.6 m. No door may be narrower than 1.2 m or lower than 2.2 m, and auditorium doors must be at least 2 m wide. A school with more than 500 sqm of floor area on any floor needs at least two staircases whatever its height (clause 7.10.2), each at least 1.5 m wide (7.11.1), and corridors of at least 1.5 m where rooms open on one side and 1.8 m where they open on both (7.11.2). Table 9.6 sets the sanitation for non-boarding schools: a WC for every 25 boys and every 15 girls, a urinal for every 20 boys, a wash basin for every 40 pupils, a drinking water fountain for every 50, and a cleaner's sink on every floor, with water planned at 45 litres per head per day (Table 9.1). For approvals, a school building below 9 m is classed as moderate risk and one of 9 m or more as high risk (clause 3.1.9).

Accessibility is built in, not added. The bye-laws' universal design chapter applies to educational buildings (clause 11.0): ramps of 1:12 for level differences up to 750 mm, handrails on both sides with their tops at 900 mm and 760 mm, and at least one unisex accessible toilet, on every floor of a multi-level building (11.3, 11.5). CBSE's own guidelines for children with special needs ask for a ramp on the ground floor with a gradient no steeper than 1:12 and 1:15 preferred, at least 1,500 mm wide, clear doors of 900 mm to classrooms, labs and toilets, and a lift or ramp wherever these children's classes run above the ground floor, with a lift car of at least 1,500 mm by 1,500 mm.

What Does the New Master Plan Allow on a School Plot?

MPD-2047, notified on 20 August 2026, which the DDA says 'supersedes the MPD-2021', sets the controls for education plots in Table 12.5. A school up to class XII needs a plot of at least 4,000 sqm on a road at least 18 m wide, with 40% ground coverage, a maximum FAR of 180 and no height restriction beyond statutory clearances; a school up to class VI needs 2,000 sqm, 40% coverage, FAR 150 and an 18 m height limit; an early learning centre 500 sqm on a 12 m road, 40%, FAR 150 and 15 m; and a special school 2,000 sqm, 50%, FAR 120 and 18 m, with a 10% variation in plot area allowed. The other controls matter to a building programme: new schools must recess the front boundary wall by 6 m for visitors' parking; at least 15% of the permissible FAR must go to extra-curricular infrastructure; up to 150 sqm of sports facilities such as squash courts, a table tennis room or changing rooms is free of coverage and FAR; up to 200 sqm may house support facilities such as shops, a bank counter or a health facility; and where space is short, playgrounds may be shared. Parking is 2.0 equivalent car spaces per 100 sqm of FAR area for a school up to class XII, 1.0 if it is run by the government or a local body, and 1.33 for a school up to class VI. For comparison, the MPD-2021 table reproduced in the DDA's 2020 compendium gave a senior secondary school 35% coverage, FAR 150 and an 18 m height. The DDA's FAQ adds that plans approved before 20 August 2026 continue under the earlier norms, and the new norms apply when additional FAR is availed or a revised plan is sanctioned.

Two conclusions follow. For a new school, the master plan's plot size for a school up to class XII, 4,000 sqm, is well above CBSE's 2,400 sqm, so check the plot against the master plan before the affiliation papers. For an existing school on a qualifying plot, the higher FAR is floor area that can be turned into certified built-up area, and, under the 2025 table, into sections, once a revised plan is sanctioned.

What Does a New School Block Cost?

At our published school construction rates of ₹2,200 to ₹4,500 per sqft, 400 sqm of new built-up area, about 4,306 sqft and 3 sections under the 2025 table, works out to roughly ₹95 lakh at the basic end and ₹1.94 crore at the premium end, before fees, furniture and equipment. The rate depends on the number of floors, the labs, air-conditioning and the fire and accessibility works. Time the structure around the school year and the winter: the Graded Response Action Plan's Stage III schedule applied in December 2025 banned excavation, masonry, and plaster and tile work except for minor indoor repairs (PIB, 13 December 2025), so heavy work belongs in the months outside that window, and noisy work in the vacations; our summer vacation maintenance guide covers how schools use the long break.
