Ultimate House Construction Checklist for Tamil Nadu (2026) – 50 Points Before You Build

Embarking on a Individual house and duplex construction project in Tamil Nadu requires meticulous planning. Whether you're building a luxury villa in ECR, an independent house in Anna Nagar, or a multi-family duplex in Vellore, missing a single step can lead to significant cost escalations or legal hurdles. We've compiled this 50-point checklist to guide you from land verification to final handover.

1. Pre-Construction Planning (Land & Legal)

Ensure your land is legally sound and structurally viable before committing to any design.

• 1. Title Verification: Ensure clear, undisputed ownership documents dating back at least 30 years.
• 2. Encumbrance Certificate (EC): Obtain a fresh 30-year EC to confirm zero pending loans or legal disputes.
• 3. Patta & Chitta: Verify that the Patta is registered under your name in the Revenue Department records.
• 4. FMB Sketch: Obtain the Field Measurement Book sketch matching physical boundaries.
• 5. CMDA/DTCP Zone Verification: Confirm if the plot falls under Primary Residential, Mixed Residential, or Commercial zones.
• 6. OSR & Road Width: Check minimum road width requirements and Open Space Reservation guidelines.
• 7. Soil Bore Testing: Conduct standard penetration tests to determine soil bearing capacity (especially crucial for coastal Chennai areas like ECR).
• 8. Water Source Assessment: Test borewell water yield, salinity, and TDS levels.
• 9. Topographical Survey: Map ground levels and plot undulations.
• 10. Physical Barricading: Secure the plot perimeter to prevent encroachment.

2. Budget & Package Selection (2026 Tiers)

Locking in a firm, transparent budget is essential. Silux Construction offers four standardized residential pricing tiers to suit different needs.

• 11. BOQ Generation: Demand a detailed Itemized Bill of Quantities (BOQ).
• 12. Payment Schedule: Align payment milestones strictly with construction progress.
• 13. Contingency Fund: Keep a 5-10% buffer for unexpected design changes.
• 14. Temporary Power Connection: Budget for TNEB commercial tariff during construction.
• 15. Turnkey vs Labor-Only: We recommend fixed-price turnkey contracts to avoid material escalation stress.
