A reservation on the Development Plan is often the reason a buyer chose one flat over another: a garden opposite, a school site behind. It is worth knowing how firmly those labels hold, because the code allows more movement than the map suggests, and less in one direction than in the other.
Key takeaways
- The uses permissible on a reserved site must conform to the purpose it is reserved for, unless specified otherwise, with parking, public toilets and a garbage bin area permitted alongside.
- Up to 40 percent of a reservation may be used for a different public purpose, provided the combination is not of incompatible uses.
- Any reservation may be developed for another public purpose with the Government's permission, but only one way: a buildable reservation may become buildable or open and recreational, while an open or recreational one may only ever become open or recreational.
- Any reservation may be taken for multi-storeyed public parking where the need is pressing, with prior Government approval.
- Zone labels on a plan are not all distinct: Regulation 4.2 treats a list of differently named zones as equivalent to the Residential Zone.
First, the label may not mean what it says
Chapter 4, Regulation 4.2, UDCPR as updated 30 January 2025* is a translation table before it is anything else, and it matters because a buyer reading a Development Plan sees zone names, not permissions.
The regulation treats a list of separately named zones as equivalent to the Residential Zone, including Residential Zone R1, Residential Zone with Shop Line R2, General Residential Zone, Urbanisable Zone, Special Residential Zone, Predominantly Residential Zone, Slum Improvement Zone, and Mix Use Zone. Residential Zones R3 and R4 are treated as equivalent too, with payment of infrastructure cost as decided by the Authority.
Two consequences follow for someone reading a plan.
A parcel labelled something unfamiliar may carry exactly the permissions of an ordinary residential plot, so an unusual zone name is not by itself a reason for concern. And "Mix Use Zone" sitting inside the residential family is worth knowing, because the name suggests a compromise between two regimes and the regulation treats it as one of them.
The R3 and R4 entry is the exception that needs a question rather than an assumption, since the equivalence there is conditional on paying an infrastructure cost the Authority sets.
If you are buying the ground itself rather than looking at it from a window, the zone is one check in a longer order, after the 7/12 extract and the conversion position and before the layout sanction: buying an NA plot in Maharashtra sets it out.
What may stand on a reservation
Chapter 4, Regulation 4.27, UDCPR as updated 30 January 2025* starts from the obvious position and then relaxes it in three defined ways.
The baseline: uses permissible on a reserved site shall conform to the use for which it is reserved, unless otherwise specified, and the required parking, public toilets and a separate place for garbage bins are permissible on the reserved site itself.
Banded by the route
- Partial use for a different public purposePermitted up to 40 percent of the reserved area, provided the combination is not of incompatible uses. Police stations and chowkys, water supply establishments, ward level waste segregation centres and other public utility services may also be established.
- Whole change of public purposeAny reserved site may be developed for any other public purpose with the permission of the Government
- The direction limitA buildable reservation may become buildable or open and recreational. An open or recreational reservation may become open or recreational ONLY.
- Multi-storeyed public parkingAny reservation may be acquired and developed for it, partly or fully, irrespective of designation, with prior Government approval where parking is direly needed and the Authority is satisfied it outranks the reserved purpose

The third band is the one that decides whether the open space opposite your flat is durable.
The rule runs one way, like a one-way street between the two kinds of reservation. A site reserved for something buildable, a school or a hospital, can end up as a garden. A site reserved as a garden or a playground cannot end up as a building, because open and recreational reservations may only be developed for open and recreational uses.
So a buyer relying on a green reservation for light, air or a view has a stronger position than one relying on a buildable reservation staying unbuilt. The parking exception in clause 4 is the qualification worth noting, since it reaches any reservation irrespective of designation, but it requires prior Government approval and a finding that the parking need outranks the reserved purpose.
Who builds it, and what the owner gets
A reservation is land someone owns and the plan has earmarked. Chapter 11 governs how it actually gets delivered, and there are three routes.
Under Chapter 11, Regulation 11.1, Manner of Development of Reserved Site in Development Plan (Accommodation Reservation Principle)*, the accommodation reservation principle, the owner develops the reserved site themselves for the purpose it is reserved for, and keeps development potential in exchange. The regulation requires that an owner allowed to develop a reservation should have exclusive ownership and title to the land, without restriction under any other Act.
Under Chapter 11, Regulation 11.2.2, Cases Eligible for Transferable Development Rights (TDR), the land goes and transferable development rights come back, since TDR is permissible for lands under reservations for public purposes, new roads and road widening which are subject to acquisition and proposed in a draft or final Development Plan.
Under Chapter 11, Regulation 11.3, Reservation Credit Certificate (RCC), the land goes and a Reservation Credit Certificate comes back instead: compensation that can be spent only on charges payable to the Authority, such as development charges, premium and property tax.
Names and numbers in this story are illustrative. When Priya and Arjun compared two Pune flats, one faced a plot marked as a garden reservation and the other faced a site reserved for a school.
Both were open ground on the day they visited. The difference Regulation 4.27(3) makes is that only one of the two can lawfully become a building, and it is not the one that looks like a garden today.
What to check
- Read the zone label against Regulation 4.2's equivalency list before drawing conclusions from an unfamiliar name.
- Establish whether a nearby reservation is buildable or open and recreational, because that decides which way it can move.
- Ask whether any part of it is already in partial use for another public purpose, and whether that stays inside 40 percent.
- Treat the parking exception as real but conditional on prior Government approval.
- Ask how the reservation is to be delivered, by accommodation reservation under 11.1 or by acquisition against TDR under 11.2.
Where the filings come in
The Development Plan is the document that answers all of this, and it sits with the Planning Authority rather than in the RERA register. The filings confirm it: of the 55,995 published MahaRERA projects as updated on 29 September 2026, 65 carry a document whose name refers to DP remarks or a zone certificate, 27 of them in Pune district.
What the register does carry is the project's own layout. A file sits in the layout approval slot on 54,272 of those projects (96.9%), and Regulation 2.2.5(a) requires a layout plan to show every Development Plan proposal within the land, so that file is where to look for a reservation on the project's own site. The plot next door still needs the Development Plan itself.
What the register adds beyond that is the reality check: which projects around that reservation were actually registered, what land they filed, and how their timelines have moved. That is free at reragenie.com, along with the promoter's extension history with the reasons given, and any complaints or litigation with case numbers.
ReraGenie's area market report, a flat Rs 2,999 per pincode, reads every registration in one pincode together. The buyer report at Rs 499 reads a single project's full filing and the documents behind it, compares the possession slip with the median for the same pincode, lists what the filings do not contain, and includes a project watch for 90 days. To hear when a new project is registered in the areas you are watching, sign up on ReraGenie: the alerts are free during the pilot beta.
