TL;DR
- Under the government's original PMAY-linked definition, dating to 2017, an affordable home is one with a carpet area up to 60 square metres in metropolitan cities (including Bengaluru) or up to 90 square metres in non-metro cities and towns, with a value not exceeding ₹45 lakh, uniformly across both categories.
- A separate RBI definition governs which home loans qualify as "affordable" for priority sector lending purposes: in cities with a population over 50 lakh, loans up to ₹50 lakh qualify provided the property value doesn't exceed ₹63 lakh, a genuinely different threshold from the PMAY carpet-area definition, and the two are frequently confused.
- NITI Aayog's December 2025 report, "A Comprehensive Framework to Promote Affordable Housing," proposed a working definition of up to ₹60 lakh in metros and ₹45 lakh in non-metros, a meaningful upward revision from the ₹45 lakh uniform cap, though this remains a think tank's proposed working definition, not a formally notified change to the actual PMAY or GST rules.
- Industry bodies like CREDAI have pushed for a considerably higher cap, up to ₹90 lakh, arguing the current ₹45 lakh threshold no longer reflects real construction and land costs in most Indian metros, a request NITI Aayog's December 2025 report notably did not adopt.
- Why this matters practically: the specific numbers determine eligibility for real, meaningful benefits, PMAY subsidies, concessional 1% GST on affordable housing construction (versus 5% on non-affordable), and priority sector lending status for your home loan, so knowing exactly which definition applies to your specific purchase is not a technicality, it's the difference between qualifying for these benefits and not.
- If a builder markets a unit as "affordable," verify independently against the actual carpet area and price against the applicable government definition, rather than accepting the marketing label at face value, since "affordable" as a sales pitch and "affordable" as a legally defined, benefit-qualifying category are not always the same thing.
Introduction
"Affordable housing" gets used constantly in Bengaluru real estate marketing, but it isn't actually a marketing phrase, it's a specific, government-defined category with real numbers attached, numbers that determine whether you actually qualify for meaningful benefits like PMAY subsidies and concessional GST rates. And confusingly, there isn't just one definition, there are at least three overlapping ones currently in use, with a fourth under active debate. Here's what each one actually says.
The Original PMAY-Linked Definition
The government's foundational definition, tied to the original Pradhan Mantri Awas Yojana framework from 2017, defines an affordable home as one with a carpet area up to 60 square metres in metropolitan cities, Bengaluru included, or up to 90 square metres in non-metropolitan cities and towns, with a value not exceeding ₹45 lakh, a cap that applies uniformly whether you're buying in a metro or a smaller town. This is the definition most directly tied to GST benefits, affordable housing construction is taxed at a concessional 1% GST rate without input tax credit, compared to 5% for non-affordable residential construction.
| Definition source | Carpet area cap | Value cap | Primary relevance |
|---|---|---|---|
| Original PMAY framework (2017) | 60 sq m (metro), 90 sq m (non-metro) | ₹45 lakh, uniform | GST concessional rate eligibility |
| RBI priority sector lending | Not area-based | Property value ≤ ₹63 lakh (in cities >50 lakh population), loan ≤ ₹50 lakh | Bank priority sector lending classification |
| NITI Aayog working definition (Dec 2025 proposal) | 60 sq m (metro), 90 sq m (non-metro) | ₹60 lakh (metro), ₹45 lakh (non-metro) | Proposed, not yet formally notified |
| CREDAI industry ask | Not specified in ask | Up to ₹90 lakh | Industry lobbying position, not adopted |
The Separate RBI Definition for Home Loans
A genuinely different definition governs whether your home loan itself qualifies as "affordable" for priority sector lending purposes, a classification that affects how banks treat the loan on their books and, in some cases, pricing. Under RBI's framework, in cities with a population exceeding 50 lakh, home loans up to ₹50 lakh qualify as affordable, provided the property's value doesn't exceed ₹63 lakh. This is worth understanding as a distinct definition from the PMAY carpet-area rule above, a property could satisfy the RBI loan-classification threshold without meeting the PMAY carpet-area and value cap, or vice versa, and the two get confused constantly in casual conversation and even in some marketing material.
The Debate That's Currently Unresolved
The ₹45 lakh uniform cap set in 2017 has increasingly diverged from real construction and land costs in most Indian metros, including Bengaluru, and this gap is the subject of active, ongoing policy debate. NITI Aayog's December 2025 report proposed a working definition raising the metro cap to ₹60 lakh while keeping the non-metro cap at ₹45 lakh, a meaningful revision, but this is a think tank's proposed working framework, not a formally notified amendment to the actual PMAY rules or GST classification. Industry bodies including CREDAI have separately pushed for a considerably higher cap, up to ₹90 lakh, arguing that even ₹60 lakh understates real costs in cities like Bengaluru and Mumbai, a request the December 2025 NITI Aayog report notably did not adopt. Until a formal notification changes the applicable rules, the original ₹45 lakh uniform cap remains the operative definition for GST and PMAY purposes.
Why the Exact Numbers Actually Matter to You
This isn't an abstract policy debate if you're actually buying a home in this price range. The specific carpet area and value thresholds determine whether your purchase qualifies for PMAY subsidy benefits, whether your builder can legitimately charge the concessional 1% GST rate rather than 5%, a distinction worth reading alongside our detailed breakdown of GST on under-construction property, and whether your loan gets classified as priority sector by your bank. A builder advertising a unit as "affordable housing" is making a claim you should verify independently, checking the actual carpet area (not super built-up area, a distinction that matters considerably here) and the actual all-in price against the currently applicable ₹45 lakh definition, rather than accepting the marketing label as confirmation that the unit genuinely qualifies for these benefits.
Conclusion
"Affordable housing" in India currently has multiple, overlapping technical definitions, a ₹45 lakh uniform PMAY-linked cap that remains the operative rule today, a separate RBI priority-sector-lending threshold of ₹63 lakh property value in large cities, and an actively debated, not-yet-adopted NITI Aayog proposal to raise the metro cap to ₹60 lakh. Knowing which definition applies to your specific purchase, and verifying it independently against your unit's actual carpet area and price, rather than trusting a builder's marketing label, is the only way to confirm you're genuinely getting the benefits the "affordable" category is supposed to unlock.
