Getting a building plan approved is a crucial step before starting any construction work. Today, most approvals are done digitally through PreDCR, and while this system has made the process faster, it has also become very strict. Even small technical mistakes can lead to rejection.
Many property owners, architects, and builders face repeated rejections simply because their drawings are not prepared correctly. This is where professional support matters. At Kraty, we help clients avoid these common errors by offering accurate and compliant building drawing online services designed specifically for PreDCR approval.
This guide explains why building plans get rejected in PreDCR, the most common mistakes, and how Kraty helps fix them with clear, compliant drawings.
What Is PreDCR and Why Is It Important
PreDCR (Pre-Development Control Regulations) is an automated software used by municipal authorities to verify building plans before approval. It checks whether your drawing follows local development rules, such as:
- Plot size and boundaries
- Setbacks and open spaces
- FSI / FAR calculations
- Building height
- Parking requirements
- Staircase and lift norms
Since PreDCR works automatically, it only reads what is drawn. If the drawing is not prepared correctly, the system rejects it—without explanation from a human reviewer.
That is why professional building drawing online preparation by experts like Kraty becomes essential.
Common Reasons Why Building Plans Get Rejected in PreDCR
Below are the most frequent issues that cause rejection and how they can be fixed properly.
1. Incorrect CAD Layer Structure
PreDCR depends heavily on correct layer naming. If layers are missing or named incorrectly, the system cannot identify building elements.
Common problems include:
- Random layer names
- Combined layers
- Missing mandatory layers
How Kraty fixes this:
At Kraty, all drawings follow authority-approved layer standards. Each element—plot, floor, parking, staircase, setbacks—is placed on the correct layer, ensuring smooth PreDCR reading.
2. Plot Boundary and Area Errors
Plot boundary mistakes are one of the top reasons for rejection. These include:
- Open or broken boundaries
- Overlapping lines
- Area mismatch with legal documents
Solution:
Kraty ensures the plot boundary is always a closed, clean polyline, with dimensions matching official land records exactly.
3. Setback Non-Compliance
Setbacks are mandatory open spaces around the building. Even a small deviation can lead to rejection.
Common errors:
- Reduced side or rear setbacks
- Setbacks not shown clearly
- Inconsistent setback values across floors
How to fix it:
With Kraty’s building drawing online services, setbacks are clearly marked on all floors and verified according to local DCR rules before submission.
4. FSI and Built-Up Area Mistakes
PreDCR calculates FSI automatically. If your drawing exceeds allowed limits, it gets rejected instantly.
Reasons include:
- Extra built-up area
- Wrong inclusion of balconies or ducts
- Manual calculation errors
Kraty’s approach:
We double-check all area calculations and ensure FSI stays within permissible limits, reducing approval risks.
5. Parking Layout Issues
Incorrect parking design is another major cause of rejection.
Problems include:
- Insufficient parking slots
- Incorrect slot dimensions
- Narrow driveways
- No clear entry or exit
How Kraty helps:
Kraty prepares parking layouts as per local norms, clearly labeling two-wheeler and four-wheeler spaces for PreDCR compliance.
6. Staircase and Lift Errors
Staircases and lifts are safety-critical elements. Rejection happens if:
- Stair width is less
- Headroom is insufficient
- Lift size does not meet norms
Solution:
Kraty ensures all staircase and lift details follow standard regulations and are shown clearly in plans and sections.
7. Building Height Violations
PreDCR checks building height based on:
- Road width
- Zoning rules
- Fire safety norms
If height exceeds limits, approval fails.
How to fix it:
Before finalizing drawings, Kraty verifies permissible height and adjusts the design accordingly.
8. Missing or Incorrect Annotations
Missing labels confuse the system and lead to rejection.
Common missing details:
- Floor names
- Road width
- North direction
- Scale
Kraty advantage:
Every drawing prepared by Kraty includes all mandatory annotations in a clean, readable format.
9. Wrong File Format or Scale
PreDCR only accepts specific file formats and scales. Many plans fail because:
- Wrong CAD version
- Mixed scales
- Distorted drawings
Fix:
Kraty submits drawings in the correct format and uniform scale, ready for approval.
10. Zoning and Land Use Mismatch
If land use in the drawing does not match official zoning, the plan is rejected.
How Kraty avoids this:
We verify zoning details before preparing the building drawing online and ensure land use is mentioned correctly in all plans.
