The Kerala CRZ layer plots the Coastal Regulation Zone footprint along Kerala's 580 km coastline and the connected backwater system, governed by CRZ Notification 2019 (G.S.R. 37(E)) with amendments up to 24 November 2022. The Kerala Coastal Zone Management Authority (KCZMA), under the Department of Environment and Climate Change, is the regulatory body. The 2019 CZMPs for all 10 coastal districts were approved by MoEFCC in November 2024, making Kerala one of only four states with an approved CZMP under CRZ 2019, alongside Odisha, Karnataka, and Maharashtra, reducing total NDZ (No Development Zone) area in Kerala from 239.431 sq km under CRZ 2011 to 108.397 sq km. This page shows what falls inside CRZ-I, II, III A, III B, and IV across Thiruvananthapuram to Kasaragod.
Kerala is the only state in India where the Supreme Court has actually ordered apartment demolitions for CRZ violations. The Maradu CRZ violation case (Supreme Court order 8 May 2019) ended with four occupied apartment complexes in Kochi imploded on 11-12 January 2020. The court rejected the builders' argument that the area was CRZ-II under the draft 2011 CZMP, holding that the 1996 KCZMP classifying Maradu as CRZ-III was the operative plan when permits were issued.
The fact-pack on what each zone permits in Kerala, drawn from CRZ Notification 2019 and the 1996/2019 CZMPs.

If a builder shows you a panchayat permit but no KCZMA recommendation, treat it the way the Supreme Court treated Maradu: void from the start. The 1996 KCZMP remained operative for clearance decisions until the 2019 plans were notified, and many disputed parcels still get adjudicated against the older map. The No Development Zone (NDZ) stacks on top of any local Town and Country Planning approval.
Kerala's coastal property market splits into three personalities. The Kochi-Ernakulam axis is mostly CRZ-II urban with selective backwater CRZ-IV B exposure. The Vembanad backwaters Kochi to Alappuzha stretch is a Critical Vulnerable Coastal Area (CVCA) with the strictest restrictions. The Malabar coast (Kozhikode, Kannur, Kasaragod) is mixed CRZ-III A and III B, where the CZMP 2019 Kerala has reclassified 37 panchayats from CRZ-III B to III A, reducing NDZ from 200 m to 50 m.

The most misunderstood corridor is the Vembanad backwater belt. Buyers see houseboats and tourism activity and assume resorts are unlocked. Vembanad is a Critical Vulnerable Coastal Area listed in CRZ Notification 2019 itself, with CRZ-I A status across mangrove and Pokkali stretches. Private resort approvals here face both KCZMA clearance and CVCA-specific restrictions, and post-Maradu the courts treat panchayat permits in this belt with deep suspicion.
