Most expensive surprises in house building are found in the land, not the building — a title gap, a paddy-land entry, a coastal or road-widening line, or ground that floods every monsoon. Every one of them is cheaper to find before you pay an advance than after you have a drawing. This guide sets out the checks in the order they are usually done for a plot in and around Thiruvananthapuram.
Start with the title
Ask for the sale deed and the earlier deeds that show how the land came to the seller. An advocate's title search commonly covers around 30 years of prior deeds; banks often look at a shorter encumbrance period, which is not a full search. Then check the revenue trail at the Village Office, which should agree with the deed on survey number, extent and owner.
- Encumbrance certificate (EC) — applied for online on the Registration Department's PEARL portal. It shows registered transactions only, so pending court cases and unregistered arrangements will not appear.
- Possession certificate, location certificate and location sketch — issued by the Village Office through e-District or an Akshaya centre.
- Thandaper number and a current land tax receipt (paid on ReLIS) in the seller's name, matching the deed.
- Mutation (pokkuvaravu) completed in the seller's name. In villages under the digital survey, a pre-mutation sketch from the Ente Bhoomi portal is now required for any transfer.
- The FMB or resurvey sketch from e-Rekha or Ente Bhoomi, so a surveyor can measure the plot against the record.
Is it nilam or purayidam? The paddy-land check
This one check decides more plots than any other. Under the Kerala Conservation of Paddy Land and Wetland Act 2008, what matters is the land's nature as on 12 August 2008 — not how it looks today. Land recorded as dry land (purayidam) in the Basic Tax Register and not in the paddy data bank is outside the Act. Filled paddy land sold as 'purayidam' while the register still says nilam is a common trap.
- Land in the data bank — removal is applied for in Form 5 to the Revenue Divisional Officer. A house on data-bank paddy land held by the owner on 12 August 2008 needs separate permission, limited to 2.02 ares (5 cents) in a municipality or corporation and 4.04 ares in a panchayat — a right personal to that owner.
- Unnotified land (recorded as paddy in the register but not in the data bank) — conversion is by permission under Section 27A, in Form 6 for land under 20.23 ares.
- Fees — conversion of holdings up to 25 cents is currently fee-free. Above 25 cents a fee based on fair value applies, and the Supreme Court held in February 2025 that it is charged on the whole extent, not just the part above 25 cents.
- A local body must not grant a building permit on land converted in breach of the Act.
Amendments to the Act's fees and timelines were under discussion in late 2026, so confirm the current position with the Village Office and an advocate before you rely on it.
Near the sea or a backwater? The coastal (CRZ) check
Kerala's Coastal Zone Management Plan under the CRZ Notification 2019 was approved in October 2024. The coastal zone runs 500 m inland from the high tide line along the sea, and 50 m (or the water body's width, if less) along backwaters and other tidal water bodies. In Thiruvananthapuram Corporation — including the Kovalam and Vizhinjam wards — and in Varkala and Attingal municipalities the coast is mostly CRZ-II, where houses are allowed on the landward side of the existing road or existing authorised buildings. Panchayats such as Kulathoor, Poovar, Kadinamkulam, Anchuthengu, Vettoor and Edava are largely CRZ-IIIA, with a no-development zone of 50 m from the high tide line.
For a house of up to 300 sq m in a coastal zone, clearance comes from the local body Secretary; larger houses go to the Kerala Coastal Zone Management Authority. The approved maps are published on the KCZMA website.
Master Plan zone, road widening and setbacks
The Thiruvananthapuram Master Plan 2040 was sanctioned in July 2024. The Corporation publishes its zoning regulations, a list of roads proposed for widening and survey-number-based land-use maps — find your plot by village, block and survey number. A building line set by the plan applies on top of the normal rule that keeps a house 3 m from a highway or a road 6 m or wider, and 2 m from a narrower unnotified road. Plots along the national highway need access permission from the highway authority, and plots in villages on the proposed Vizhinjam–Navaikulam outer ring road should be checked against its alignment.
Access: road width and right of way
The building rules set no minimum access width for a single-family house up to 300 sq m, but a car, a concrete mixer and a fire tender still need real width. If the only way in is a private pathway, make sure the right of way is written into the registered deed rather than relying on long use, and check whether the road is public or private. Narrow access also adds handling cost to every load of material — see what moves construction cost.
The ground itself: soil, water, flooding and slope
- Soil — most of the district's midlands are laterite; there is red loam to the south, a narrow strip of sandy coastal alluvium, and clayey valley soils where paddy once grew. Filled marshy land may need deeper foundations or piling, so order a soil test before the structure is designed.
- Flooding — the Irrigation Department's 2021 report records repeated monsoon flooding around Thampanoor, East Fort, Uppidamoodu and Kannammoola. Ask neighbours, look for water marks and note the nearest canal and low point.
- Slope and landslide — the State Disaster Management Authority publishes landslide susceptibility maps; panchayats along the Western Ghats edge, such as Vithura and Peringammala, need particular care.
- Drains — natural drains and streams crossing a plot must not be blocked; the building rules restrict building on flood-liable land.
- Water and sewage — a septic tank must sit at least 7.5 m from a drinking-water well, which on a small plot fixes the layout. Check the well, the water table and whether a sewer or piped water line is nearby.
Other clearances and a quick first check
Depending on location, a plot may also need clearance for airport height (much of the city lies within 20 km of the airport), a railway within 30 m, a protected monument within 300 m or high-tension lines overhead. The K-SMART 'Know Your Land' service shows whether a plot falls in coastal, master-plan, airport, railway, landslide or HT-line zones — a fast first screen, though not a substitute for the record checks above. Our K-SMART permit guide explains the next stage.
Who to bring in, and when
- An advocate — for the title search and a written legal opinion, before any advance.
- A licensed surveyor — to measure the plot against the FMB or resurvey sketch and mark the boundaries.
- A soil-testing laboratory — before the structure is designed.
- An engineer or architect — to confirm what can be built: setbacks, coverage and the permit route. See what fits on a 5-cent plot.
Check the land before you fall for the house. A plot that fails one of these checks is expensive at any price.
