A different kind of requirement
Most Indian cities state parking as a count: so many car spaces per tenement or per 100 sqm. Hyderabad does not. Rule 12 of the Telangana Building Rules 2012 (adopted from the AP Building Rules issued under G.O.Ms.No.168) sets the requirement as a percentage of total built-up area, with a column for each authority. For GHMC:
| Use | Parking area |
|---|---|
| Residential apartment complexes, hospitals, educational, industrial | 30% |
| Commercial, business, hotels, restaurants, cinemas, offices, kalyana mandapams | 40% |
| Shopping malls above 4,000 sqm, IT/ITES complexes, multiplexes | 60% |
Visitor parking is inside the percentage. There is no separate two-wheeler count.
What "60% of built-up area" means on a plan
A 10,000 sqm IT building must show 6,000 sqm of parking. At the 25 to 32 sqm per bay that geometry produces, that is roughly 190 to 240 cars — but the rule never says so. It says area.
This is the crux for mechanical parking. A stacker that parks 60 cars in 600 sqm has, on the face of the rule, provided 600 sqm — a tenth of what a conventional layout would need for the same cars. Whether GHMC credits the system at its capacity or at its footprint is decided at scrutiny, by an area-per-car equivalence that the rule leaves to the authority.
Getting the equivalence in writing
- Before design, submit the parking plan with the mechanical system's capacity, bay sizes and the area it occupies.
- Ask GHMC Town Planning to confirm the area per car it will credit for that system — the HMDA checklist references figures around 22% inclusive of visitors for certain layouts, which shows the authority does apply conversions.
- Record the reply in the sanction file. It is the single document that makes the mechanical scheme compliant.
Why it matters commercially
A percentage-of-area rule is generous to buildings that can afford conventional parking and severe on tight plots. For a developer, the question is not "how many bays" but "how much saleable area does the parking percentage consume" — which is exactly the number a mechanical system can change, provided the equivalence is agreed first.
