Why not file yourself

The OSR portal allows DIY filing in theory. In practice, most homeowners encounter issues: incorrect drawing formats, document compilation errors, fee calculation queries, and the inevitable objection responses that need expert handling. Homeli files for ₹15,000–₹50,000 consultant fee and saves you the 60-90 day timeline that DIY filings typically incur due to objection cycles.

Frequently asked

How do I apply for CMDA approval online in Chennai?
Through the CMDA OSR (Online Single Window) portal. Steps: (1) create application, (2) fill form with project details, (3) upload architect-signed drawings as PDFs in specified formats, (4) upload document set (patta, EC, tax, ID), (5) pay fees online, (6) wait for site verification (1-2 weeks), (7) sanctioned plan issued. Homeli does the portal filing on your behalf.
Can I file CMDA online myself without a consultant?

Drawings need specific formats, documents need specific compilation, fees need correct calculation, and objection responses need expert handling. DIY filings typically take 60-90 days due to objection cycles. Homeli files for a fee that saves 30-60 days.
What format should I upload drawings in?
CMDA OSR portal accepts drawings as PDFs in specified sheet sizes (typically A2, A1) with architect signature, registration number and standard scale. Specific file naming conventions and folder structures apply. Homeli's drawings are prepared in the right format from the start.
Can I pay CMDA fees in instalments online?
No — all fees (development charge + scrutiny + security deposit + infrastructure) must be paid in full at the time of filing. The portal calculates total automatically and requires full payment via net banking or UPI before the application enters scrutiny.
How do I track my CMDA online application status?
Through the OSR portal dashboard under your application reference number. Common statuses: submitted, under scrutiny, site verification scheduled, objections raised, sanctioned, sanctioned plan ready for download. Homeli tracks your file daily and updates you on changes.
Can I download my sanctioned plan online?
Yes — once approved, the sanctioned plan is available for download from the OSR portal with the CMDA stamp and approval number. Homeli downloads and shares with you as a PDF + provides a hard copy for bank loan and utility connection applications.
