How to Check if a Property is in an FTL or Buffer Zone in Hyderabad

Since 2024, property buyers in Hyderabad have had a new question to answer before paying: is this land inside the full tank level or buffer zone of a water body? Getting it wrong has cost families their homes and their savings. Public records are a starting point; unclear boundaries can require certified records, a site survey and legal review.

This guide sets out exactly how to check — the official portal, what each record tells you, and the cross-checks most buyers miss. There is also a free FTL & buffer zone risk check tool that produces a personalised checklist.

Open the official HMDA lakes portal. Search by district, mandal and village, or use the lake name or ID. Keep the maps and notification dates for the correct lake. This website is an independent legal-information resource, not the government portal.

First, the two terms

Full Tank Level (FTL) is the level a lake or tank reaches when it is full, and by extension the land area within that boundary. Construction inside the FTL of a notified water body is impermissible.

Buffer zone is a prescribed strip beyond the FTL within which construction is restricted. The published building rules distinguish lakes/tanks/kuntas of 10 hectares and above: 30 metres from the FTL boundary, and those below 10 hectares: 9 metres. For canals, vagus, nalas and storm-water drains, the stated distances from the defined boundary are 9 metres where the watercourse is more than 10 metres wide and 2 metres where it is up to 10 metres wide. Confirm the classification, certified boundary, applicable current rules and any site-specific restriction; do not measure from the current water edge. See G.O.Ms.No.168, rule 3(a) and the current HYDRAA FAQs.

Note the second half of that: nalas and storm-water drains carry buffer restrictions too. This catches more buyers than lakes do, because drains are routinely covered over and invisible on the ground while still appearing on alignment records.

The official source: the HMDA lakes portal

The primary public record is the HMDA lakes portal at lakes.hmda.gov.in. It covers Hyderabad, Medchal-Malkajgiri, Rangareddy, Sangareddy, Medak, Siddipet and Yadadri-Bhongiri districts.

Step 1 — Find the lakes for your village

Select the district, then the mandal or circle, then the village. You may also search directly by lake name or lake ID. The portal displays matching records. An empty result or missing map is not evidence that no water body or restriction exists.

Step 2 — Read the notification stage, not just the name

For each lake the portal shows a Date of Preliminary Notification and a Date of Final Notification. This distinction matters and most buyers ignore it:

• A preliminary notification publishes the proposed boundary and opens the stage at which objections can be made. The demarcation is not yet concluded.
• A final notification records the published final stage. Read the actual notification and check for later corrections, orders or litigation affecting it.

Record which stage applies to your lake and both dates. If only a preliminary notification exists, that is relevant both to objections that may be filed and to any later challenge to the demarcation.

Step 3 — Download the FTL map and the cadastral map

The portal publishes two maps against each lake. The FTL map shows the water body boundary. The cadastral map is the more useful one for a buyer, because it overlays survey boundaries against the FTL line — which is how you locate your plot rather than a general area.

Read the legend on the specific map to identify its FTL, buffer and other lines. Colours and drawing conventions can differ; do not classify a property from a colour alone. Match the lake ID, village, survey details and map version.

Step 4 — Check the affected survey numbers

This is the step that actually answers the question. For each lake, the portal publishes a statement of survey numbers and the area affected in the FTL and buffer zone. Search it for the survey number of the land you are buying.

A critical caution: finding your survey number on that list does not mean the entire plot is affected, and not finding it is not a clearance. Listings are by survey number and area, and an FTL or buffer boundary can pass straight through a survey number — leaving part of it affected and part not. That is precisely why the cadastral map and a physical examination on the ground both matter.

The cross-checks buyers usually skip

1. Nala and storm-water drain alignment. Verify the drain alignment for the location against local body records. A covered drain is still a drain.
2. Master plan land use. Confirm the land use for the plot in the GHMC or HMDA master plan, and whether any additional restriction attaches to the area.
3. Ground truth. Have the boundary position examined physically against the cadastral map. Paper and ground diverge more often than people expect.
4. Agricultural land. Verify the pattadar passbook, extent and current record of rights on Bhu Bharati — the system that replaced Dharani in April 2025 — and note the Bhudhaar number where available.
5. Apartments. Verify the project on Telangana RERA, then verify the underlying land’s FTL position separately. A RERA registration is a project registration, not a finding on FTL.

What approvals do and do not protect

Approvals matter a great deal. A layout approval, a sanctioned building plan and an occupancy certificate are among the strongest documents you can hold, and their absence is a serious weakness.

But it is important to be honest about their limits. An approval is not a finding that land lies outside an FTL or buffer zone, and a seller cannot convey a better title than they hold. Families in Hyderabad who held valid permissions have still faced action — which is why the verification above is done independently, and why every approval, plan, receipt and utility record should be preserved rather than filed away.

Before you pay: a short discipline

• Begin document and portal checks before paying a booking or token amount. Clarify refund conditions and resolve material uncertainties before committing further money or beginning construction.
• Get the survey number in writing from the seller, and verify it against the documents rather than trusting a spoken figure.
• Ask the seller directly, in writing, whether any notice, signboard, survey or proceeding concerns the land — and keep the reply.
• Where anything is unclear, have the documents examined before committing money. The extent and cost of a review depend on the property and missing records.

If the records are unclear or a notice has arrived

Collect the lake ID, FTL and cadastral maps, affected-survey statement, sale/link deeds, approvals and any notice or order with its date. Request missing or certified records from the relevant HMDA, Irrigation, Revenue or local-body office. A survey number can be partly affected; a map screenshot cannot settle the exact position of a plot.

For a document-review enquiry, use the contact page and state the locality, survey number if known, issue and notice deadline. Do not include identity numbers or original documents in the initial message. A notice response or challenge needs case-specific advice; submitting this form does not extend any deadline.
