DCR & Building Bye-laws — Indian Cities

Why a city-by-city DCR reference?

Setback rules and FSI vary dramatically across Indian cities — and even within a city by zone, plot size, road width, and building height. The official Development Control Regulations of any large municipality run to 400-700 pages of legalese, with conditional rules buried inside cross-referenced tables. A homeowner trying to confirm a 1.5 m versus 2.0 m side margin, or an architect verifying maximum FSI for a given road width, wastes hours scrolling PDFs. InfraLens distils each city's regulation into structured tables, worked examples for common plot sizes, and a setback calculator that answers the lookup in one click — while linking back to the source clause for verification.

This directory is not a substitute for ULB approval. It is a fast, free first-pass reference for owners, contractors, junior architects, and structural engineers who need accurate setback and height constraints to start a feasibility study or plot purchase decision.

What's covered in each city page

Every live city page includes: front (road-side) setback as a function of abutting road width; side and rear margins by plot size for single-family dwellings, and by building height for apartments and other uses; maximum permissible building height by road width; margin between buildings on the same plot for group housing; worked examples for typical plot sizes (30×40, 40×60, 60×90 ft) on common road widths (9, 12, 18 m); and a search-citable source link to the official ULB notification PDF.

Upcoming additions per city: FSI/FAR by zone, ground coverage limits, parking requirements (per ECS / per dwelling unit), common plot / open space rules for layouts above 4,000 sq.m, and special-zone overlays (heritage, riverfront, transit-oriented, smart-city node).

How city DCRs differ across India

Indian Development Control Regulations follow several lineages. Gujarat uses a unified state-wide CGDCR 2017 covering all ULBs (AMC, SMC, VMC, RMC, etc.) with category bands D1 to D10 capturing different urban densities. Maharashtra uses Development Control and Promotion Regulations (DCPR) at municipal corporation level — Mumbai's DCR 2034, Pune's DCPR 2017, Nagpur's DCPR 2020 — each with its own zone vocabulary and FSI bands. Karnataka combines BDA's Revised Master Plan (RMP-2031) with BBMP's older Building Bye-laws 2003 plus subsequent amendments. Delhi layers DDA's Master Plan-2041 with MCD Building Bye-laws 2016 plus GRAP/air-quality-zone rules. Tamil Nadu issued the unified TNCDBR 2019 covering all civic bodies. West Bengal, UP, MP, Telangana, and Rajasthan each maintain separate frameworks.

Because the *structure* differs city to city, InfraLens does not force every city into a one-size-fits-all schema. Each city's data file mirrors its source regulation's vocabulary (zones, categories, plot bands) so what you read on the page exactly matches what you'd find in the official PDF — just easier to query.

Where the data comes from and how it's verified

Every page is built from the official notification PDF of the issuing authority — Government of [State], Urban Development Department, or the relevant Municipal Corporation. We do not aggregate from blogs, third-party sites, or older repealed editions. Source URLs are visible at the top of each city page ("Download [Regulation] PDF" button). Last-reviewed dates are stamped per page; cities that have undergone an amendment since first publication are flagged.

Because regulations have legal weight (incorrect setbacks can lead to demolition orders or development permission denial), we mark each new city page as "Draft — pending human verification" until a registered architect or relevant authority practitioner has reviewed the values. Cities that have completed verification show no draft badge.
