Bengaluru homebuyer glossary: 150 real estate terms from A-Khata to UDS

Property papers, keys and a notebook laid out on a desk

Short answer: This glossary explains 150 real estate terms India's homebuyers meet, with a Bengaluru focus. It's grouped by topic: area, documents, approvals and land records, khata and tax, RERA and disputes, money and charges, loans, and the building. Each term gets a plain definition and, where it matters, what to check.

Key takeaways
  • 150 terms in 8 groups, alphabetical within each group, with jump links below.
  • Some terms have two meanings. "CC" can mean commencement or completion certificate. Always ask which.
  • Area terms move money. Always price on RERA carpet area.
  • Karnataka has its own vocabulary: khata, e-Aasthi, e-Swathu, RTC, Kaveri, guidance value.
  • Our OMP decode: ask whether a term changes your Ownership, your Money, or your Permission to build, live or sell.

Property paperwork in India mixes central law, state rules and local jargon. A Bengaluru sale deed might mention UDS, a khata number, a survey number and an EC in one paragraph. This page is a reference: find the term, read the plain meaning, and follow the link if you need the full check.

How do you decode an unfamiliar term? (the OMP decode)

When you meet a word you don't know in a document, ask what it changes. That tells you who to ask.

If the term changes your... Examples Who to ask
Ownership Title, sale deed, UDS, JDA share, mortgage, encumbrance Your lawyer
Money Guidance value, GST, stamp duty, loading, LTV, TDS Your CA or lender, and your own maths
Permission to build, live or sell Sanctioned plan, OC, khata, conversion order, setback The approving authority's records, and your lawyer

Most terms below are tagged O, M or P so you can see which bucket they fall in.

What do the area terms mean?

  1. Balcony area (M). The balcony's floor area. RERA carpet area excludes exclusive balconies and verandas, so check how the agreement lists them.
  2. Built-up area (M). Carpet area plus the thickness of the flat's walls, and sometimes the balcony. Definitions vary by builder.
  3. Carpet area, RERA (M). The net usable floor area of a flat, excluding external walls, service shafts and exclusive balconies, but including internal partition walls (RERA Act s.2(k)). It must be stated in the agreement.
  4. Common areas (O). Lobbies, lifts, staircases, terraces, grounds and amenities shared by all owners. They're handed to the association.
  5. Floor area ratio, FAR or FSI (P). The total floor area allowed on a plot divided by the plot area. It sets how much can be built.
  6. Loading (M). The gap between super built-up and carpet area, as a percentage of carpet area. Higher loading means you pay for more space you can't use.
  7. Plinth area (M). The covered area at floor level including walls, used in construction estimates.
  8. Plot area (O). The area of the land parcel, usually in sq ft or sq m; in rural records, in acres and guntas.
  9. Saleable area (M). A market term, usually meaning super built-up area.
  10. Setback (P). The open space that must be left between a building and the plot boundary under zoning rules.
  11. Super built-up area (M). Built-up area plus your share of common areas. Many quotes use it, which hides the loading.
  12. Terrace rights (O). Whether an owner has exclusive use of a terrace. Check the agreement and sale deed.
  13. Undivided share, UDS (O). Your proportionate share of the land under the building, registered in your name with the flat.

Worked example 1: what's your UDS?

A project sits on 1 acre (43,560 sq ft). The total super built-up area of all flats is 60,000 sq ft. Your flat is 1,500 sq ft super built-up.

Step Calculation Result
Your share of total area 1,500 ÷ 60,000 2.5%
Your UDS 2.5% × 43,560 sq ft 1,089 sq ft

Builders don't all use super built-up as the basis; some use carpet area. Check the method in the agreement, and check the sale deed states the UDS. A smaller UDS than expected can matter if the building is ever redeveloped.

  12. Mother deed (O). The earliest title document in the chain, showing how the seller's predecessors got the property.

Checklist: terms to confirm in your own documents

  • [ ] RERA carpet area matches across agreement, sale deed and RERA filing
  • [ ] UDS is stated in the sale deed, with the method
  • [ ] EC covers 30 years (Form 15 or 16)
  • [ ] Khata type (A or B) and status (draft or final e-khata) are known
  • [ ] "CC" is clarified: commencement or completion
  • [ ] OC is issued for your tower if the flat is complete
  • [ ] Guidance value checked on Kaveri
  • [ ] GST rate (5%, 1% or nil) confirmed
  • [ ] Mortgage on the project, and the lender's NOC, confirmed
  • [ ] Delay interest clause matches section 18

What mistakes do buyers make with property terms?

  • Treating e-khata as a new khata type. It's a digital record of either A or B.
  • Confusing the two CCs. A commencement certificate isn't a completion certificate.
  • Comparing super built-up prices. Use carpet area.
  • Assuming mutation proves title. It doesn't; the title chain does.
  • Ignoring UDS. It's your share of the land.
  • Taking GPA sales at face value. A GPA alone doesn't transfer ownership.

What should you do if...

...a term in your agreement isn't here? Ask your lawyer, and ask the builder to define it in writing.

...two documents use different areas? Ask which is the RERA carpet area and get it fixed before signing.

...the guidance value is above your price? Budget for stamp duty on the higher figure.

...your flat has a B-Khata? Read our khata guide before you go further.

...the possession date passes? See our guide to refund or interest under section 18.

...you're buying a plot? Check the conversion order; our section 95 guide explains it.

Where can you go deeper?

Method notes and limits

  • RERA definitions are from the Act's text (ss.2(k), 3(2), 4(2)(l), 11, 13, 14, 18, 43(5), 71). Charges are from our full cost guide, checked on official sources on 18 Oct 2026.
  • Loan figures use an illustrative 8.5% rate and RBI's loan-to-value caps.
  • Definitions are simplified for buyers and aren't legal definitions. Terms can mean different things in different documents.
  • Lawyer note: for title, deeds and approvals, rely on your lawyer. CA note: check capital gains, indexation, TDS and GST with a CA.

Frequently asked questions

UDS is your undivided share of the land under the building. It's usually worked out in proportion to your flat's area and should be stated in your sale deed.

Carpet area is the usable floor inside your flat, as defined in RERA. Super built-up area adds walls and your share of common areas. The gap is the loading.

A record from Kaveri of registered transactions on a property, such as sales and mortgages, for a period you choose. Form 16 means none were found.

A-Khata is the register for properties that comply with approvals. B-Khata records properties with approval or bye-law gaps. Loans and resale are easier with A-Khata.

The government's minimum value per unit area for a property. Stamp duty is paid on the higher of the price and the guidance value.

It can mean commencement certificate (permission to start building) or completion certificate (confirmation the building is complete). Always ask which one.

Permission to occupy a building, issued after the authority checks it against the sanctioned plan. Don't take possession of a new flat without one.

A joint development agreement, where a landowner provides land and a builder develops it, and the flats are split between them. Check whose share your flat is in.
