25% Built does NOT mean the construction is incomplete. It means the plot owner has fulfilled the mandatory minimum construction requirement set by GMADA — which is 25% of the total permissible FAR (Floor Area Ratio). Once this minimum is done, the owner can apply for an Occupation Certificate (OC). This is a legal compliance milestone. A plot with 25% Built has higher value than a bare plot in some cases, as the owner has already fulfilled the authority's building obligation.
