Dear Client,

With the consent all the Flat Owners, there need not be any issue in the matter. 

Dear Client,

Open parking comes under common area, cannot be put to use for personal purpose even for safety purpose without members consent. Further allotment of parking is without payment to builder otherwise than to could have erect the shed as matter of right and ownership.

Since no society is formed, get it erected, rest will c later.

The car parking space is a part of common space and hence no one can make any physical partition and cause constructions over it , even if the same is of temporary nature.

So if the other flat owners are opposing your acts then not breaching any provision of law.

In other words do not do this anymore as if the other flat owners decide to file suit then your problem would increase.

However there is no harm if you make a tarpaulin shed by erecting bamboo poles.It is likely attract lesser attention from other flat owners.

There must be mention g of parking space in the sale deed. If it is not there then make a separate sale deed for the parking space without which your ownership over the parking space is never established.

you cannot  erect temporary car shed in open car parking slot without permission from municipal corporation and builder 

You can issue legal notice to builder to issue you allotment letter for parking slot

If you have paid for it than only notice recommended.

you can file a complaint in co-operative court also you can send a letter to the society in case if society is formed or else you can directly write a letter to the builder for providing you parking space with allotment of letter. 

See it is not illegal to erect the shed see but the parking is allotment basis the allotment can be changed by builder or society after you erect such shed also. You can take NOC from.builder for making such shed.

No open parking spaces are common area and builder cannot sale same it can be just alloted.

What you desire is blatantly illegal. 

You can only errect temporary shed but if society opposes then you need to approach court. 

1. Open /Stilt /Podium Parking spaces are all classified as "common open spaces" under the Regional Town Planning Act and CANNOT be Sold or Purchased or Registered . Parking spaces can be allotted (most of the times by illegally collecting money, which is a criminal offence).

2. In Maharashtra, it is a prosecutable offence to enclose  "ANY" open car parking slots and is an offence under the local Civic Laws, the MRTP Act and the Fire Act.

Only if the project is Rera registered, can builder sell the car park

Otherwise its a part of common areas and not saleable

Also erecting a shed will require municipality permission 

You do not need permission of flat buyers

However even under Rera open car park cannot be sold 

What can be sold is a garage or covered or stilt car park

Builder has duped you

First of all  the neighbor members of the apartment complex  has nothing to do with you covering your parking space  until and unless it is disturbing anyone's space in any manner.

The builder who has allotted the parking space can intervene but he will not do so because the conversion of open parking space into  a covered one is not in the approved plan and it may be an illegal act and he will be responsible if he is giving permission.

you may not bother about  other members objections to this, let them do anything, if they are going illegal about it you may approach police fora criminal action against them.

You can issue a legal notice to the builder asking him to allot   a covered car parking space , let him give a reply after which you can decide about further legal course of action on this issue.

Dear Sir,

Yes, you can get issue a legal notice to builder.

In most of cases, builder also mark/reserve open parking with numbers and only "those" who have paid... can use parking slot... those who dont pay OR using extra car.. can not park into other slot.
