Short answer
What are building bye-laws and what do they control? Building bye-laws are the rules of a town or authority on whether a building needs a permit and how it may be built. The Model Building Bye-Laws 2016 are only a model for States and local bodies. Its chapters cover definitions, permits, development codes, room and service requirements, structural safety, fire and more. Your town's own bye-laws apply.

“Building bye-laws” is a phrase everyone uses and few owners have read. This page says what they are, what a model set of them contains chapter by chapter, and, more usefully, how to find the rules that apply to your own plot. It prints no setback, FAR, height, parking or fee figure, because those come from your town’s own rules, not from a model. For the figures themselves, see setback rules explained and FAR and FSI explained.
What are building bye-laws, and who makes them?
Bye-laws are the rules a town, city or development authority uses to control building. The Model Building Bye-Laws (MBBL) 2016 say that building bye-laws are legal tools “to regulate coverage, height, building bulk, and architectural design and construction aspects of buildings so as to achieve orderly development of an area” (Prelude). That sentence describes real, adopted bye-laws. The MBBL themselves are a different thing: the Prelude says the Town and Country Planning Organisation prepared them “for the guidance of the State Governments, Urban Local Bodies, Urban Development Authorities”, and hopes they will be useful to States, local bodies and development authorities “in revising their respective Building Bye Laws”.
So there is no single national rulebook. NBCS 2026 says so about itself: regulation of land development and buildings is a State subject, handled by States and local bodies through “building regulations, development control rules building byelaws, and fire regulations”, and the NBCS “is voluntary in nature and is non-binding”. It also says administrative provisions, land use requirements such as FAR, development control rules and parking norms, open spaces and ground coverage are left to local and State government and are not in the NBCS.
The MBBL say the same in their own words: the bye-laws “shall apply to the building activity in the State/Urban Center/Town for which they are framed” (clause 2.1). In practice, towns call their set by different names, such as building bye-laws, development control regulations or unified building bye-laws. For the process of getting a plan sanctioned, see building plan approval: process and documents.
What does each chapter of the model control?
The table lists the chapters of the 2016 model and what each controls. Use it as a map of what a town’s bye-laws usually cover. It is not your town’s content.
| Chapter | Title in the model | What it controls |
|---|---|---|
| Prelude | (unnumbered) | Why the model exists and who it is for |
| 1 | Definitions | Meaning of terms such as Authority, Building, Master Plan and Zonal Plan (1.1); and that the Master Plan regulations on use, coverage, FAR, set-back, open space, height and parking carry into the bye-laws (1.0) |
| 2 | Jurisdiction, applicability and building documentation procedures | Where the bye-laws apply, when a permit is needed (2.8), documents and signing of plans (2.10, 2.11), exempt minor alterations (2.12), sanction (2.14), the owner’s duties during construction (2.15), notice of completion and occupation (2.16 to 2.18) |
| 3 | Development codes | Use, ground coverage, FAR, set-backs, open space, height, density and parking, which the chapter says come from the Master Plan, Zonal Plan or Development Code |
| 4 | General building requirements and services | Requirements for rooms, kitchens, bathrooms, basements, parapets, boundary walls, septic tanks, staircases, light and ventilation (4.30) and plumbing |
| 5 | Provisions for high rise development | Tall buildings, not an ordinary house |
| 6 | Provisions for structural safety | Structural design by a structural engineer on record, with reference to the National Building Code (6.1), and inspection (6.3) |
| 7 | Special requirements for occupancy, land development and other | Special buildings, signs and outdoor display structures (7.13), and penal action for violations (7.12) |
| 8 | Provisions for differently-abled, elderly and children | Access provisions |
| 9 | Rainwater harvesting | Rainwater harvesting systems and enforcement |
| 10 | Green buildings and sustainability provisions | Green building provisions and applicability |
| 11 | Fire protection and fire safety requirements | Fire clearance and fire safety |
| 12 | Conservation of heritage sites | Heritage buildings and precincts |
| 13 | Streamlining of building plan approvals | Approval process reforms |
| 14 | Climate resilient construction | Environmental clearances with sanction |
| Appendices | Forms and proformas | Application forms, undertakings, notices and certificates |
How do the chapters split the work?
Chapter 3 says what the rest depends on. Its opening paragraph says the provisions of the Master Plan, Zonal Plan or Development Code apply, “where these are silent on such issues or which require interpretation the norms as decided by the Authority, shall apply”. It adds that “the object of these regulations is to provide control for building/buildings within use premises excluding the internal arrangement, which is covered and controlled by Building Bye-Laws”. So in the model, the Chapter 3 regulations (use, coverage, FAR, setbacks, open space, height and parking) control the building within its use premises, and the internal arrangement is left to the bye-laws. Chapter 4 also has outside items, such as open spaces around the building, parapets and boundary walls.
The model has no clause that ranks the Act, the Master Plan and the bye-laws against each other. It says the Master Plan regulations apply with the bye-laws, and amendments to them stand included (1.0). Its heritage chapter is an exception, with its own rules for heritage areas. So if your plot’s zoning and your town’s bye-laws seem to disagree, ask the authority, and do not assume.
What does an owner meet in the model?
These clauses are examples of what a town’s bye-laws usually say. Your own town’s wording and numbers may differ.
- Permit: “No person shall erect, re-erect or make addition/ alterations in any building or cause the same to be done without, first obtaining a separate building permit for each such building from the Authority” (2.8.2).
- Exemptions: the model lists minor alterations that need no notice and permit, such as plastering and patch repairs, re-flooring, painting and white-washing, so long as they do not violate the provisions of the bye-laws on general building requirements, structural stability and fire safety (2.12.1).
- Owner’s duty: “Neither the granting of the permission nor the approval of the drawings and specification, nor inspection by the Authority during erection of the building, shall in any way relieve the Owner of the building from full responsibility for carrying out work in accordance with these Bye-Laws” (2.15.1(a)).
- Structure: design is done by a structural engineer on record or a structural design agency on record (6.1).
- Penalties: the model names penal action in clause 7.12 and in an appendix, under the respective Acts, so what actually applies is set by your authority’s Act.
The model refers to the National Building Code, naming the 2005 edition in several places, but also saying the latest version is to be taken into account at enforcement (4.30). The National Building Code 2016 has been replaced by SP 7:2026 (NBCS 2026): see IS codes for house construction. Ask your authority which one your town’s bye-laws point to.
How do I find the bye-laws that apply to my plot?
This is practice, not a standard.
- Find out who sanctions your plot: a municipal body, a development authority or a gram panchayat. Ask the local office.
- Look on that authority’s website and the State town planning or urban development department’s site for “building bye-laws”, “development control regulations” or “unified building bye-laws”, and the gazette notification.
- Get the latest consolidated copy and every amendment, and note the date of each.
- Find the Master Plan or Zonal Plan and the zoning map for your plot: the use zone, the road width and any overlay such as heritage, airport height, coastal, hill or flood areas.
- Ask your architect for a one-page rule sheet with clause numbers, the edition and date of the rules, and the road category used.
- Read the notes and conditions on the sanctioned plan. They say which rules were applied.
- If a copy is not available, ask the office for an official copy and answers in writing, or file an RTI request.
- Treat a neighbour’s sanction, a blog’s table or another city’s rules as clues, never as the rule.
A useful rule sheet (practice) covers the authority and the date of the rules, when a permit is needed and what is exempt, the use zone, plot-size-based controls, ground coverage, setbacks and building line, FAR, height and storeys, parking, room sizes and ventilation, staircase and fire basics, basement and stilt rules, plinth level, rainwater and sanitation, overlays, documents needed, stage certificates and validity of the sanction. Topics only: the numbers come from your town. See also working drawings for a house for what drawings are checked against these rules.
What mistakes should I avoid?
These are practice, not code rules.
- Using a neighbour’s old sanction, a blog’s table or another city’s rules.
- Assuming the model bye-laws, or the National Building Code, apply to your house directly.
- Confusing the Master Plan zoning with the bye-laws.
- Relying on verbal assurances instead of a written rule or a clause number.
- Not checking amendments or the date of the rules on the sanctioned plan.
- Ignoring overlays such as heritage, airport height, coastal, hill and flood areas.
- Reading the rules only at approval, and not at the plinth check, completion and later alterations.
- Leaving it all to the architect. The model says approval does not relieve the owner (2.15.1(a)).
- Deviating on site without a revised sanction.
Frequently asked questions
What are building bye-laws?
The rules a town, city or authority uses to control building: when a permit is needed, how a plot may be used, and how a building must be arranged, serviced and made safe.
Are building bye-laws the same across India?
No. They are made by States and local bodies. The Model Building Bye-Laws 2016 are a model for their guidance.
Do the Model Building Bye-Laws 2016 apply to my house?
Only if your State or town has adopted them or framed its bye-laws on them. The model says bye-laws apply to the town for which they are framed (clause 2.1).
What is the difference between bye-laws and the National Building Code?
The code is a voluntary technical document. NBCS 2026 calls itself non-binding, with force only where adopted or adapted, or made a contract condition. Bye-laws are made locally and can make parts of it binding.
Where do I find my town’s building bye-laws?
On the local authority’s or the State planning department’s website, or from its office. Ask for the latest copy and the amendments.
