The development process for any area is mainly guided by the master plan of the area or the stipulation of the local bodies like corporation etc.  
The zones earmarked for development are to be strictly developed in accordance with the planning documents. The buildings in the area are to be constructed strictly in accordance with building plans approved which are in accordance with the Unified Building Bye Laws or the BBL as we call it. The extent of construction, the height, etc are determined and the builder is allowed to construct the building as per the said plan which is often referred to as the Sanctioned Plan or the Building Plan. The entire set up of regulatory bodies and laws are very complex and unclear on various issues thereby creating confusions. The issue regarding applicability of various types of laws on various types of lands is basically area specific. The number of bodies involved in regulating and sanctioning are involves which makes the entire scenario so complex that even the legally trained brains are twisted in dealing with such issues. Here are some scenario which can give a better idea about it.
  •        Getting the approval of the residential township or colony from the state urban development authority.
  •        Getting the lay out plan of the area sanctioned or approved by the local authority
  •        Getting the go ahead or NOC from the landowning agency
  •        NOC from the Airport Authority, Military Authority, Naval Authority for the project in terms of height clearance, location etc of the project.
  •        NOC from the forest department or any regional authority which controls the developmental activities of the area
  •        NOC from the pollution control board of the authority based on the size of the project which is often called the “consent to establish”.
  •        Getting NOC from the fire department regarding the fire safety measures propsed to be taken in the project.
  •        Getting the building plan sanctioned which includes the floor plans of the building in accordance with the allowed Floor Area Ratio or the FAR as we call it.
  •        Getting the sewer, water connections sanctioned and installed as per the norms
  •        Getting the lift erection plan approved and getting the lift license after the completion of the erection of the lift.
  •        Getting the NOC for the electrical sub station HT/LT as the case may be.
  •        Getting the completion/occupation certificate (CC or OC) from the local building authority which certifies the building safe for human habitation.
  •        Getting the permission for sale/lease of the property from the landowning agency if applicable. 

The Major Areas Of Concern :
1)  LAND OWNING AGENCY: 
The rules, regulations governing the terms and conditions of the subject land, the nature of title given by the land owning agency, the rights of the purchaser etc are of vital importance. In most of the urban areas the ownership rights of developed properties is often vested with the landowning agency, in some cases with the developer and in some cases with all. This makes the legal aspects of the title very confusing and unclear due to which project financing, mortgaging, transfer etc becomes legally impermissible thereby creating a serious embargo on the development of the properties of the said area. The said property in true sense can not become a real estate as the owner can not mortgage it or put to some other uses. The end result is the manipulations, misrepresentations and overlooking of the existing laws. This uncertainty pushes the real players out from the market and those who can manipulate the system thrive to earn huge profits.
2) LAND USE: 
The land use assumes importance from the point of view of enforcement of the real estate laws as the nature of the use of the land directly determines the price and the availability of the property. In most of the metropolitan cities in Indian the enforcement of the land use was initially ignored as a result of the same big commercial establishments were constructed on agricultural land without any sanction and without any approval, the said properties were sold to unsuspecting buyers and the developers took the lion share out of the premium. Now with the growing thrust on the land use , the cost of the property is determined by the various aspects of land use attached to it.
3) BUILDING PLAN REGULATIONS:
 The regulations of the building plans in the metropolitan cities has created such a scenario that event the trained architects, legal minds are unclear about the extent of the construction, the use of the basement, common areas etc. The recent judgment by Supreme Court about the misuse of the basement areas, common areas, residential areas etc has further complicated the already mixed up things. In urban areas one has to take NOC from several bodies like the army, air force, navy as the case may be , airport authority, urban art commission, local building law sanctioning authority, pollution control board etc before commencing any kind of construction.
4) TENANCY LAWS: 
The applicability of the tenancy laws in the    metropolitan cities is a major issue determining the extent and nature of real estate trading in the said area. In cities like Mumbai, Delhi, Calcutta we find stringent tenancy laws restricting the rights of the property owners in taking back their properties from the tenants or fetching rents in accordance with the prevalent market rates. The Apartment Acts, Cooperative House Building Societies Acts, Slum Area Development and Clearance Acts are some of the Legislation which operate in various metropolitan cities with their peculiarities and shape the Real Estate Laws of the particular city.
In such confusing  situation coupled with the temptation of very good returns one has to look into various aspects of the matter before investing or buying any real estate in the urban areas. We are giving some brief tips in this regards which may form very handy and useful for the unsuspecting investor who is often out in the market to buy a dream house.
