House map approval in Kerala

Online on K-SMART (Kerala Solutions for Managing Administrative Reformation and Transformation), the Local Self Government Department's portal at ksmart.lsgkerala.gov.in, to the Secretary of the corporation, municipality or grama panchayat where the plot lies. Corporations and municipalities moved to K-SMART on 1 January 2024, when the Intelligent Building Plan Management System (IBPMS) stopped taking applications, and grama panchayats followed in April 2025, after the old Sanketham software closed to new applications on 29 March 2025. The drawings and site plan must be signed by a registered licensee, and you add the title deed or a registered lease of at least 10 years.

It is the quick route for low-risk buildings, which for a home means under 300 sq m built-up and no more than two storeys, not counting a basement. The 29 October 2025 amendment dropped the old 7 m height limit and let any registered licensee sign, not only specially empanelled ones. You and the licensee certify that the plans follow the rules and that the plot meets the coastal zone rules and the 2008 paddy land and wetland law, and you attach any no-objection certificates needed. The Secretary must issue an acknowledgement certificate within five working days, and it counts as the permit. Work that digs deeper than 1.5 m cannot use this route.

Plots of up to 125 sq m (about 3 cents; one cent is 40.47 sq m) come under special small-plot rules: three floors and a stair room up to 10 m high, with no floor space index, ground coverage, access-width or parking limits, and smaller yards for a house of up to 200 sq m built-up. The relief is not for an owner who splits land into several such plots and keeps more than one, or who owns the plot next door. On a plot of up to 81 sq m beside an un-notified road no wider than 3 m, a house of up to 100 sq m and 8 m may stand 1 m from the road if the owner has no other land.

At least 3 m from a national highway, state highway, district road, notified road or any un-notified road 6 m or wider, and 2 m from a narrower un-notified road. For a house up to 8 m high, a cul-de-sac up to 250 m long or a residential colony road needs 2 m, and a lane up to 75 m long 1.5 m, or 1 m if it serves five plots or fewer beyond yours and their owners agree in writing. On plots under 5 cents, underground septic tanks, wells, sumps and rainwater tanks may sit 1.2 m from the road. Beside national highways, a Supreme Court interim order of 13 April 2026 in a national road-safety case bars new houses within 40 m of the road's centre line; Kerala asked the court to relax it in October 2026, so check before you buy such a plot.

A person or institution registered under the building rules. An architect registered with the Council of Architecture, an Engineer-A or a Building Designer-A can sign the plans for any building permit; an architect may also do the structural design for up to 500 sq m and three storeys or 11 m, and an Engineer-A for anything short of a high-rise. Supervisors have limits: Supervisor-B up to 300 sq m and two floors, 7.5 m high; Supervisor-A up to 750 sq m and three floors, 11 m; Supervisor Senior up to 1,000 sq m and four floors, 14.5 m, all plus a stair cabin.

The Secretary has 15 days to approve the site and 15 more to decide on the permit; if nothing comes, write to the municipal council or village panchayat, and its silence for about a month makes the permit deemed. The application fee is ₹150 for a house up to 100 sq m and ₹500 up to 300 sq m, and above that ₹4,000 in a corporation, ₹3,000 in a municipality and ₹2,000 in a panchayat. The permit fee per sq m for a house is ₹5, ₹20, ₹70 or ₹150 in a corporation (up to 80, 150 and 300 sq m, then above), ₹3.50, ₹17.50, ₹60 or ₹150 in a municipality and ₹3.50, ₹25, ₹50 or ₹100 in a panchayat. A permit lasts five years and can be extended once by five more for 10% of the permit fee.

Yes. A plot inside a notified Coastal Regulation Zone needs the Kerala Coastal Zone Management Authority's no-objection certificate first. Under Kerala's coastal zone plan, approved by the Centre on 24 September 2024, municipal (CRZ-II) areas have no fixed no-build strip, while in rural areas it is 50 m from the high tide line in denser CRZ-IIIA areas, and in CRZ-IIIB 200 m from the sea and 50 m from backwaters. The permit form asks how the land is recorded in the Basic Tax Register and in the data bank under the Kerala Conservation of Paddy Land and Wetland Act 2008. Land recorded as paddy but left out of the data bank needs the Revenue Divisional Officer's permission under section 27A; up to 25 cents (as held on 30 December 2017) pays no fee, larger holdings 10% of the fair value and over an acre 20% (Supreme Court, 20 February 2025).

Under the Kerala Municipality Act 1994 the Secretary can order the work stopped and the unlawful part demolished or altered after a show-cause notice, demolish it at your cost and prosecute you; the fine runs up to ₹10,000 plus ₹1,000 for each day it continues. Until it comes down, such a building pays three times the normal property tax and gets a special number instead of a regular building number. Work that breaks no rule can be regularised on a compounding fee. If a self-certified house breaks its plan, the owner and the licensee each pay ₹2 lakh (up to 100 sq m), ₹4 lakh (up to 200 sq m) or ₹6 lakh (up to 300 sq m), under both the Municipality and Panchayat Raj Acts, and the licensee can be barred for at least five years.
