Which rules does this page explain?
This page explains the Phase 1 Telugu ebook. The building values come from its inserted revision, on PDF page 8. They are historical reference values.
The ebook is not a complete set of current building rules. Confirm the approved plot zone and later amendments before you prepare a building application.
Minimum area, FSI, coverage and storeys
Read each row as one building type. A larger plot does not automatically qualify for every use or height. G+3 means ground floor plus three upper floors.
The cellar/basement count is a separate row in the source. It is not extra residential or commercial floor area in our calculator.
| Type | Minimum plot | FSI | Coverage | Storeys | Basements |
|---|---|---|---|---|---|
| Detached house | 120 | 2.00 | 70% | G+3 | 0 |
| One-side attached house | 120 | 2.00 | 70% | G+3 | 0 |
| Row housing / housing cluster | 120 | 2.00 | 70% | G+3 | 0 |
| Apartment 1 | 360 | 2.10 | 70% | G+5 | 0 |
| Apartment 2 | 600 | 2.20 | 60% | G+5 | 2 |
| High-rise 3 | 2400 | 2.30 | 50% | G+11 | 3 |
| High-rise 4 | 4800 | 2.80 | 50% | G+11 | 3 |
| Group development | 4800 | 2.80 | 50% | G+11 | 3 |
Open space around the building
A setback is the space between a plot boundary and the building. Keep the front road side separate from the rear. All values below are in feet.
A zero in this old table is not a general right to build on any boundary. The approved building type and site conditions still control.
| Type | Front | Side 1 | Side 2 | Rear |
|---|---|---|---|---|
| Detached house | 6.6 | 3.3 | 0 | 3.3 |
| One-side attached house | 6.6 | 6.6 | 0 | 6.6 |
| Row housing / housing cluster | 6.6 | 0 | 0 | 6.6 |
| Apartment 1 | 10 | 6.6 | 6.6 | 6.6 |
| Apartment 2 | 10 | 10 | 10 | 10 |
| High-rise 3 | 23 | 23 | 23 | 23 |
| High-rise 4 | 23 | 23 | 23 | 26 |
| Group development | TP | TP | TP | TP |
Read the revision correctly
The earlier table gives FSI 1.75 for the first three house types. The inserted table changes each to 2.00.
Apartment 1 changes from 1.75 to 2.10. Apartment 2 changes from 2.00 to 2.20.
High-rise 3 changes from 2.00 to 2.30. High-rise 4 and group development change from 2.40 to 2.80.
Coverage rises from 60% to 70% for the first four columns. Several 6.50 ft setbacks become 6.6 ft. Use one complete table; do not mix them.
R3 group-development setbacks are marked TP. The ebook does not provide numeric values there. Our tool leaves the footprint result unavailable.
Uses listed in the booklet
The earlier R3 panel lists homes, apartments, guest houses, professional residences, small grocery shops, ATMs, art galleries and community facilities among its permitted uses.
It also lists uses that need special permission. Examples include hostels, supermarkets, hotels, banks and private educational or health facilities.
These are translated examples from PDF page 7. They are not a current permission list. Check the detailed zone schedule for the proposed activity.
Before a building application
Use the building-area tool to understand the calculation. Take the result and your plot papers to a qualified designer.
- Confirm the plot number, boundaries and registered area.
- Get the approved layout and exact zoning category.
- Check road width, corner conditions and any road widening.
- Ask the designer to check parking, fire access, height and structural requirements.
- Apply the current water, energy and greenery requirements.
- Obtain the required approval before construction.
