Which checks can be automated?
Most early-stage bye-law checks are calculations on geometry, which makes them good candidates for automation:
- FAR — countable floor area divided by plot area
- Ground coverage — footprint as a share of plot area
- Setbacks — minimum distances from boundaries and roads
- Height — overall building height against the permitted limit
- Egress — travel distances to exits and staircase provision
Why do the rules have to be set up per authority?
Building rules in India sit in layers: the National Building Code, state and city bye-laws, and master plans. What counts towards FAR, which balconies or service areas are exempt, and how setbacks change with road width or height all differ between authorities. A tool that calculates FAR "in general" is not enough — it must apply the rules of the authority where the project is located.
What does a worked example look like?
An illustrative residential plot, using simple rules:
| Item | Rule (illustrative) | Design | Result |
|---|---|---|---|
| Plot area | — | 500 m² | — |
| FAR | Maximum 2.0 | 960 m² countable | 1.92 — complies |
| Ground coverage | Maximum 60% | 280 m² footprint | 56% — complies |
| Front setback | Minimum 3.0 m | 3.0 m | Complies |
| Side setbacks | Minimum 1.5 m | 1.2 m on one side | Fails — revise |
The value of automation is that these figures update the moment the design changes, so the failing side setback is caught at concept stage rather than at approval.
What data does an automated check need?
- Plot boundary, road edges and road widths
- Building footprint and height
- Closed room areas on every floor, tagged by use
- The rule set and exemptions of the local authority
Clean geometry matters more than clever software. Rooms drawn as open lines, or floors without consistent levels, are the most common reason checks fail.
What are the limits?
- Interpretation. Exemptions and special cases need an architect's judgement.
- Changing rules. Bye-laws are amended; rule sets need an owner who keeps them current.
- Fire and life safety. Egress checks support, but do not replace, professional fire-safety design.
- Responsibility. The architect signs the submission; the authority decides.
How do you set it up step by step?
- Choose the authority and rule set for your typical projects.
- Prepare clean geometry — plot, roads, footprint and tagged rooms.
- Configure the checks and thresholds, including exemptions.
- Test on approved projects and compare with the approved figures.
- Use on live projects with review before every submission.

Frequently asked questions
Can software calculate FAR automatically?
- Yes, if rooms and floors are modelled as clean areas and the tool knows which areas the local authority counts towards FAR. Exemptions such as certain balconies or service areas must be configured for each authority.
Are bye-law rules the same across India?
- No. Rules come from state and city bye-laws and master plans, which differ on FAR, setbacks, ground coverage and what is exempt. Checks must be set up for the authority where the project is located.
Can AI check egress and travel distances?
- Software can measure travel distances to exits and flag rooms that exceed a limit, but fire and life-safety compliance, including the National Building Code requirements, must be confirmed by a qualified professional.
Does an automated check replace the approval drawing review?
- No. It catches problems earlier and saves rework, but the architect remains responsible for the submission and the authority makes the decision.
What data does an automated compliance check need?
- A plot boundary, road edges and widths, building footprint, floors with closed room areas tagged by use, building height, and the rule set of the local authority.
