Getting building approval before starting construction is one of the most critical and often confusing parts of building a house, commercial space, or industrial project in India. With digital systems replacing old pen‑and‑paper submissions, approvals have become faster and more transparent but only if your building designs drawing and documentation are prepared correctly.
In this guide, we’ll walk you through how PreDCR drawings and approval works in online building permission systems, especially in the context of Indian municipalities and development authorities. We’ll also explain why accurate building designs drawing matter and how services like Kraty help you succeed in the approval process.
What Are PreDCR Drawings? A Clear Definition
In simple terms, PreDCR drawings are building plan drawings prepared in a specific format required by online building plan approval systems. These systems — often powered by software like AutoDCR — automatically read and evaluate architectural plans against your local development control rules and building regulations.
The word PreDCR itself is short for “Pre‑Development Control Rules format” — meaning the drawing must be prepared before submitting to the online approval system, in a way that the software can automatically interpret and scrutinize the design.
Unlike regular architectural drawings, PreDCR drawings are highly standardized. They follow exact layers, labels, and formatting so that approval engines can automatically identify things like:
- Plot boundaries
- Setback areas
- Floor area calculations
- Room uses
- Parking, openings, stairs, and circulation areas
This automation simplifies verification and reduces time spent in manual checks by authority staff – provided the drawing meets the strict formatting requirements.
Why PreDCR Matters for Online Building Permissions
Digital building permission systems – which many municipal corporations and development authorities have mandated use of AutoDCR or similar engines to scrutinize building designs drawings before granting approvals.
If your drawings are not in PreDCR format:
- The system cannot read your drawing automatically
- The application gets rejected or returned for correction
- You waste time, money, and effort re‑submitting
So the lion’s share of the hassle in building permission revolves around preparing and submitting compliant pre‑formatted building designs drawing. This is where PreDCR drawings come in — they are the foundation of a smooth online approval process.
How Online Building Permission Systems Work — Step by Step
The process can vary slightly depending on local rules and software, but most online building permission systems follow the same general stages:
1. Project Planning & Sharing Initial Details
Before anything else, you or your architect must provide details like:
- Site address & plot dimensions
- Proposed building type (residential, commercial, industrial)
- Owner / engineer / architect information
- Any existing structures on site
This information gets entered into the online portal. At this stage, the system often generates a unique application number to track progress.
2. Preparing Your Building Designs Drawing in the PreDCR Format
This is the most important step for success.
Your architectural drawings must be converted into PreDCR format using software like PreDCR utilities (a CAD tool) so that:
- Objects are drawn on correct layers
- Entities are closed polylines
- Dimensions, floor plans, and room labels are correct
- Plot setbacks, parking and circulation details are accurate
If the software finds a missing label or an incorrectly closed area, it might flag errors or prevent automatic assessment.
This drawing phase ensures that your design — including the structural and architectural intentions — can be automatically checked by the system against local development control rules. That’s why this drawing phase is often the make‑or‑break step in the entire approval workflow.
3. Uploading Drawings & Supporting Documents
Once your PreDCR drawing is ready, integrated building permission portals allow you to upload:
- The PreDCR building designs drawing
- Ownership and plan documents
- NOCs (if applicable)
- Structural drawings
- Any other required certificates
Everything is submitted online, eliminating the need to visit multiple government offices.
4. Automated Scrutiny and Error Checking
After uploading, the online system’s automated scrutiny engine checks your PreDCR drawing against local building rules, such as:
- Maximum floor area ratios
- Setback requirements
- Height limits
- Parking standards
- Fire safety provisions
Accepted drawings move forward for processing; rejected ones come back with error messages to be corrected.
This automated process significantly reduces manual intervention and speeds up turnaround time as long as your drawings are properly formatted.
5. Government Review & Queries
Once your plan passes the automated scrutiny, it goes to the planning authority or municipality for a final review.
Here officials may:
- Check legal documents
- Issue queries for clarifications
- Ask for additional technical details
If everything is satisfactory, your permission gets approved and you receive official documentation online.
Common Challenges in PreDCR & Approval
Even though online systems are more efficient than manual systems, there are a few common issues people face:
1. Incorrect Layers or Entities in PreDCR Drawing
Each entity (like room, wall, window, etc.) must follow strict naming and layer conventions. Failing this leads to errors that software generates.
2. Missing or Improper Name Labels
If the plan does not clearly label areas (for example “Bedroom” or “Living Room”), the system might overlook or misinterpret sections of the drawing.
3. Manual Cancellations & Resubmissions
If the drawing isn’t compliant, you often have to correct and re‑submit, which adds days or weeks of delay.
4. Lack of Compliance Expertise
Many people find it difficult to interpret building bye‑laws and PreDCR requirements without professional help.
