Who approves your Mumbai plot (MCGM, SRA, MHADA or MMRDA), why DCPR 2034 and not UDCPR applies, how the 2025 NA reform works here, and the IOD to OC path on AutoDCR.
Before you rely on any of this: building regulations, fee schedules and portal addresses change often, sometimes several times a year. This guide was updated in October 2026 for Maharashtra's 2025 land revenue reform, which changed how agricultural land is converted. Everything below links to its source. Always confirm the current position on the official portal, or with an architect who has recently filed in your ward, before you spend money or sign anything. This is a plain-English guide, not legal advice.
Mumbai plays by its own rulebook, and most mistakes here begin with advice imported from elsewhere in Maharashtra. Most plots in Greater Mumbai are approved by the Municipal Corporation of Greater Mumbai (MCGM) under DCPR 2034, through an online system your architect files on. Slum rehabilitation, MHADA layouts and a few MMRDA areas follow separate tracks, so the first question is never "what can I build" but "who decides".
Land conversion, the big topic for plot owners in Pune or Nashik, matters far less here. Greater Mumbai is almost entirely built up, and its development plan has no agricultural zone. Where a record does still show agricultural use, the 2025 reform means the building permission now does the conversion. Details are in step two.
This decides the rulebook, the portal, the fees and the timeline.
If the seller cannot tell you which of these applies, treat that as a warning sign. Our plot due diligence checklist covers the other checks to run before you pay.
Greater Mumbai runs on the Development Control and Promotion Regulations for Greater Mumbai, 2034 (DCPR 2034). The State sanctioned them with the Draft Development Plan 2034 by a notification of 8 May 2018, and they came into force on 1 September 2018, replacing the DCR of 1991. MCGM publishes the full text with its sanction notification at mcgm.gov.in, and the State publishes later modifications, such as the 14 March 2024 change to Regulation 33(10), on maharashtra.gov.in.
Two scope rules are worth knowing:
So FSI, setbacks and parking figures you read for Pune or Thane do not carry over. For a primer on those terms, see our explainer on setbacks, FAR and height limits.
Most Mumbai plots are identified by a city survey (CS or CTS) number or a Town Planning Scheme final plot number, which is how DCPR 2034 itself tells you to look up a plot's zone. The ownership record for these is the property card, and MCGM's portal notes that a digitally signed property card can be pulled in during submission. A few areas still carry survey and hissa numbers and a 7/12 extract alongside the CTS number. Both are on mahabhumi.gov.in, the state land records portal.
Check three things before anything else:
The land use zones in DCPR 2034's zoning table are residential, commercial, industrial, a No Special Development Zone, two port zones, Natural Areas and a Green Zone. None of them is an agricultural zone. Agriculture appears only as a permitted low-intensity use in some zones. We could not find an official figure for how much land in Greater Mumbai is still recorded as agricultural, so we will not invent one. In practice, most people building in Mumbai never deal with NA conversion.
If your record does still show agricultural use, the rules changed recently. The Maharashtra Land Revenue Code (Second Amendment) Act, 2025 replaced the old system of a Collector's NA permission or deemed-conversion sanad followed by an annual NA tax (bill text, PRS India). The reform was put into effect by a Government Resolution in February 2026 (Punekar News); Government Resolutions are published at gr.maharashtra.gov.in. In short:
What has not changed: the use must be permitted by the plan. If the zone does not permit housing, as with most land marked Natural Area, a building permission for a home will not be granted, and the reform does not help. We also could not find Mumbai-specific guidance on how the premium is applied to the few plots still recorded as agricultural, so confirm it with the Collector's office for Mumbai City or Mumbai Suburban before you budget. For how the same reform plays out where farmland is common, see our Pune guide covers it in more depth.
MCGM handles construction permits through a single window on its AutoDCR portal, which it describes as the official website for the construction permit system. One common application form goes in, and the NOCs it needs (fire, traffic, tree, electrical, revenue, Airports Authority and National Monuments Authority, where relevant) are routed through the same system. MCGM says this cut the process from 42 steps to 8.
The stages you will hear about:
You cannot file this yourself. MCGM's FAQ says applications go through a registered architect or licensed surveyor registered with BMC, who must also upload construction progress and site photographs twice a month while work is on. The same FAQ says architects can grant approval for low and moderate risk buildings under a State notification, so ask yours whether your project qualifies. MCGM also has an online fee calculator.
Plinth checking happens once the plinth is complete. The authority checks that what has been built matches the approved plans, and only then is the CC extended above plinth. MCGM's FAQ says the plinth CC is issued within 3 working days of compliance being submitted online. Building higher without it turns small deviations into demolition.
The OC cum BCC is what makes the building legally fit to occupy. You apply through a Common Completion Request Form, without visiting each department, and MCGM says the completion certificate is granted within 7 working days if documents are complete and the work matches the approval. Without it, utility connections, resale and home loans all get harder, and buyers' lawyers ask for it first.
If you are buying into a promoted project rather than building yourself, verify its registration on MahaRERA before paying anything. For a realistic budget once approvals are in hand, see our Mumbai and Thane construction cost breakdown.
Usually not, and rarely at all. Most Mumbai land is already urban and never needs conversion. Where a record still shows agricultural use, since the Maharashtra Land Revenue Code (Second Amendment) Act, 2025 there is no separate Collector's permission if the plan permits the use: the planning authority's permission effects the conversion, with a one-time premium.
No. UDCPR expressly excludes MCGM and the other planning authorities within its limits. Greater Mumbai follows DCPR 2034.
No. Those lie outside Greater Mumbai, so DCPR 2034 and MCGM do not apply. UDCPR covers most of the region, but it names exceptions such as NAINA and MIDC areas, so confirm the rulebook with the local authority. Being in the Mumbai Metropolitan Region is not the same as being in Greater Mumbai.
Then MHADA's Building Permission Cell or the SRA is the planning authority, not MCGM, and the project runs under Regulation 33(5) or 33(10) of DCPR 2034. Establish this before any design work, because FSI and rehabilitation obligations change entirely.
