The problem we kept meeting
Every parking enquiry starts with the same question: how many bays does the regulation require? The answer lives in a different document in every city, UDCPR in Maharashtra, DCPR 2034 in Greater Mumbai, the Telangana Building Rules, TNCDBR in Tamil Nadu, KMC's rules in Kolkata, BBMP's bye-laws, CGDCR in Gujarat, the UBBL and Master Plan in Delhi. Consultants' summaries circulate for years after amendments; some still quote Mumbai's 1991 table.
An architect who designs to the wrong figure loses months at scrutiny. A developer who sizes a plot to it loses more.
What we built
The Compliance Atlas is a public reference: one page per city, with the requirement by building type, the two-wheeler and visitor loadings, the bay sizes, the mechanical-parking clause and its conditions, the fire rules that apply, and a dated log of every change since we verified it. A calculator runs on the verified rows.
The rule we hold to
A figure appears on the public page only when an application engineer has read it in the regulation and recorded the clause. Where our desk research found a figure in only one secondary source, the row is loaded but hidden until it is confirmed. Where we could not find it, the page says so, "in verification", rather than guess.
That means some city pages launch with the mechanical-parking provisions verified and the requirement table still pending. We think that is more useful than a complete table nobody should trust.
What it is not
It is not a sanction, and it does not replace the regulation. Every row links to the clause so that the architect can cite the authority document, not us. When a requirement changes, we log the amendment, re-verify the affected rows and tell the people who asked to follow that city.
How to help
If your city is not published, ask for it on the Atlas page; verification order follows demand. If you find an error, tell us, with the clause. That is how the Atlas gets better.
