Overview
The Karnataka CRZ layer plots the Coastal Regulation Zone footprint along the state's 320 km coastline on the Arabian Sea. It mirrors the Coastal Zone Management Plan approved by MoEFCC at the National Coastal Zone Management Authority's 45th meeting on 1 September 2022, prepared under CRZ Notification 2019 (G.S.R. 37(E)) for three coastal districts: Uttara Kannada, Udupi, and Dakshina Kannada. The Karnataka State Coastal Zone Management Authority (KSCZMA) is the regulatory body. Karnataka is one of only four approved states under CRZ 2019, alongside Odisha, Maharashtra, and Kerala (Kerala's 10 districts approved October 2024). This page shows what falls inside CRZ-I, II, III A, III B, and IV across the Karnataka coast.
Regulatory Red Flags Around Karwar, Coondapur and the Sewage-Polluted Stretch
Karnataka has two of India's listed Critical Vulnerable Coastal Areas: Karwar and Coondapur CVCA (Critical Vulnerable Coastal Area), both named explicitly in CRZ Notification 2019 alongside Sundarban, Vembanad, and Gulf of Mannar. The CAG (Comptroller and Auditor General) performance audit also documented untreated sewage discharge from 11 of 12 coastal urban local bodies in Karnataka directly into the sea. Only Mangalore City Corporation operates a 100% sewage network with four treatment plants.
The fact-pack on what each zone permits in Karnataka, drawn from CRZ Notification 2019 and the approved Karnataka CZMP.

The Karnataka-specific trap is the assumption that local panchayat or town panchayat approvals override CRZ. The CAG audit flagged two specific Karnataka violations: four additional berths at New Mangalore Port and a petroleum product storage terminal at Karwar. If a parcel sits along the Tulu-Konkan stretch in Ullal, Mulki, Saligrama, Honnavar, Kumta, or Ankola, where eight cities still depend on septic tanks and soak-pits, expect tighter enforcement once sewage compliance is forced through KSCZMA review.
Growth Corridors From Mangalore to Karwar Across the Tulu-Konkan Belt
Karnataka's coast splits into three personalities. The Mangalore Udupi Karwar coast stretches across Dakshina Kannada urban (CRZ-II dominated), Udupi semi-urban with mixed CRZ-II and CRZ-III, and Uttara Kannada largely rural (CRZ-III A and III B). The Karnataka Tourism Policy 2020-26 has identified all three coastal districts as Focus Tourism Destinations, with KSCZMA clearance mandatory for any hotel, resort, jetty, or shack on the 92 beaches mapped in the CZMP Tourism Plan. The Karnataka Tourism Policy 2020-26 expires in 2026 — verify whether a successor policy has been notified before relying on tourism-permit assumptions.
The corridors most asked about, mapped against CRZ classification under the approved Karnataka CZMP.

The most misunderstood corridor is the Gokarna-Kumta-Honnavar belt. Buyers see beach-resort listings and assume CRZ-III B at 200 m NDZ is the only constraint. Eight municipalities along this stretch (Ullal, Mulki, Kundapura, Saligrama, Honnavar, Kumta, Ankola plus partial Bhatkal) have no sewerage network. Resort approvals in this belt now require sewage treatment as a condition of KSCZMA recommendation, regardless of zone classification.

Frequently Asked Questions
Karnataka CRZ covers the entire 320 km coastline within 500 metres of HTL (High Tide Line), plus 50 metres along tidal water bodies. It is governed by CRZ Notification 2019 and the Karnataka CZMP approved by MoEFCC on 1 September 2022, applicable across Uttara Kannada, Udupi, and Dakshina Kannada districts.
Karnataka's approved CZMP is under challenge in two cases before the NGT Southern Bench. If either challenge succeeds, the approved CRZ 2019 rules may be modified or reverted. Buyers in North Karnataka's coastal belt should track these proceedings.
Match your survey number against the approved Karnataka CZMP map available from KSCZMA or the Department of Tourism head office. The classification will read CRZ-I A, CRZ-I B, CRZ-II, CRZ-III A, CRZ-III B, or CRZ-IV.
Use 1acre's Premium map layer (https://1acre.in/subscribe) to overlay the MoEFCC-approved Karnataka CZMP boundary on your survey number before approaching KSCZMA for a CRZ clearance application.
Yes, but only beyond the NDZ in CRZ-III, on the landward side of existing roads in CRZ-II. KSCZMA clearance through Parivesh portal is mandatory regardless of MUDA, UDA, or panchayat approvals. CRZ-I parcels (mangroves, dunes, CVCA) cannot be built on.
Karnataka's 320 km coastline crosses Uttara Kannada, Udupi, and Dakshina Kannada districts, and most CRZ-III villages here fall in CRZ-III B (≤ 2,161 persons per sq km under Census 2011), which carries a 200 m No Development Zone from the High Tide Line. Densely-populated CRZ-III A pockets — including parts of Mangaluru, Udupi, Karwar, and Kundapur — get a relaxed 50 m NDZ. Along the Sharavati, Netravati, Kali, and other tidal water bodies in coastal Karnataka, the NDZ is 50 m or the creek width, whichever is less. Always pull the Karnataka CZMP 2019 zone for the parcel before relying on broker claims.
KSCZMA recommends clearance for CRZ-II and CRZ-III projects through the Parivesh portal under MoEFCC F.No. IA3-12/1/2022-IA.III dated 29.11.2022. CRZ-I and CRZ-IV proposals require MoEFCC clearance at the Centre. Local Self Government Institutes have limited delegated powers.
Yes. CRZ Notification 2019 paragraph 3.1 lists Karwar (Uttara Kannada) and Coondapur (Udupi) as Critical Vulnerable Coastal Areas. Both are managed with fisher community involvement, classified as CRZ-I A, and no private construction is permitted within the notified buffer zones.
NGT Southern Bench has ordered status quo on Karwar commercial port expansion — buyers near Baitkhol should verify current order status before any transaction.
Yes. NCZMA approved the Karnataka CZMP at its 45th meeting on 1 September 2022. Karnataka is among the first four states with an approved CZMP 2019, alongside Odisha, Maharashtra, and Kerala (Kerala's 10 districts approved October 2024). The Tourism Plan 92 beaches Karnataka annexure is part of this approved CZMP.
Karnataka's approved CZMP is under challenge in two cases before the NGT Southern Bench. If either challenge succeeds, the approved CRZ 2019 rules may be modified or reverted. Buyers in North Karnataka's coastal belt should track these proceedings.
Yes for non-agricultural land, subject to FEMA rules and KSCZMA clearance for any construction. Agricultural land purchase by NRIs faces standard RBI restrictions. CRZ classification does not bar ownership but freezes development rights inside NDZ regardless of buyer category.
