A tenant who turns a let-for-residence flat into a shop, or a cycle-repair workshop into a showroom, may be inviting eviction. Under the Karnataka Rent Act, 1999, change of user is a distinct statutory ground for recovery of possession, but it is hedged by two strict safeguards: the landlord must show the user was changed without his written consent, and he must first serve a notice giving the tenant one month to stop. This note maps Section 27(2)(c), its statutory ancestor in Section 108(o) of the Transfer of Property Act, 1882, and the Supreme Court learning that decides when a change is real and when it is merely an expansion of the same trade.

What "change of user" means

"User" in rent-control parlance is the purpose for which premises are occupied, not merely the physical activity inside them. A change of user occurs when a tenant employs the premises for a purpose materially different from that for which they were let, for example converting a let-for-residence house into business premises, or a workshop into a different commercial venture. The concept is rooted in Section 108(o) of the Transfer of Property Act, 1882, which obliges a lessee not to "use, or permit another to use, the property for a purpose other than that for which it was leased." The Karnataka Rent Act, 1999, lifts this common-law duty into a self-contained eviction ground, but with procedural protections the bare Transfer of Property Act never gave. The starting point for any change-of-user dispute is therefore the agreed or implied purpose of the letting, which connects directly to the statutory definitions of "premises" and "tenant" and to the broader scheme set out in the Karnataka Rent Act hub.

The statutory ground: Section 27(2)(c)

Section 27 of the Karnataka Rent Act, 1999, opens with the protective rule that no court shall pass an order for recovery of possession save on the grounds enumerated in sub-section (2). Among those grounds, clause (c) covers change of user: it allows the landlord to recover possession where the tenant "has used the premises for a purpose other than that for which they were let, without obtaining the consent in writing of the landlord." Two ingredients are thus indispensable. First, there must be a genuine deviation from the let purpose; second, the deviation must be unauthorised, that is, made without the landlord's written consent. Oral permission or mere acquiescence does not, on the face of the clause, defeat the ground, though long acquiescence may feed into the consent or waiver enquiry. The use of "a purpose other than that for which they were let" mirrors Section 108(o) of the Transfer of Property Act and invites the courts to read the two provisions harmoniously.

The phrase "without obtaining the consent in writing of the landlord" is the pivot of clause (c). It means a tenant who can produce written authorisation, whether in the rent deed itself or in a later writing, has a complete answer to the change-of-user ground. Conversely, the absence of any restrictive stipulation in the tenancy can also help the tenant, because a permissive or silent contract widens the band of permissible user. This is the lesson of Gurdial Batra v. Raj Kumar Jain (AIR 1989 SC 1841; (1989) 3 SCC 441), where premises let for a cycle and rickshaw repair shop were also being used, temporarily, to sell televisions. The Supreme Court noted that the rent note contained "no stipulation that the appellant would not do any business in the shop except the cycle or rickshaw repairs," and set aside the eviction. Where the contract does not narrow user, the tenant's freedom is correspondingly wider, and the landlord cannot manufacture a breach out of activity the lease never forbade.

The mandatory notice and one-month cure period

Clause (c) is unusual among eviction grounds in giving the tenant a statutory chance to cure. The proviso bars any application on this ground unless the landlord has first given the tenant a notice, by registered post and served personally, requiring him to stop the misuse, and the tenant has refused or failed to comply within one month of service of that notice. This makes the notice a condition precedent: an eviction petition filed without it, or before the month has run, is premature and liable to be dismissed. The cure period reflects the Act's tenant-protective philosophy, the same philosophy that animates the structured grounds for eviction generally. A prudent tenant who receives such a notice and reverts to the original user within the month effectively extinguishes the cause of action, because the statutory default, refusal or failure to comply, never crystallises. The mode of service is itself part of the safeguard: the statute prescribes registered post and personal service, so a landlord cannot rely on a casual oral demand or informal message. The notice must also be intelligible, specifically identifying the misuse complained of, so that the tenant knows precisely what conduct he is required to discontinue. Because the proviso is cast in mandatory terms, courts treat the notice and the lapse of the one-month period as jurisdictional facts that the landlord must plead and prove; their absence is not a curable irregularity but goes to the very maintainability of the petition. A landlord who serves the notice, waits out the month, and finds the misuse continuing has then, and only then, a complete and actionable ground under clause (c).

Expansion of trade is not change of user

Not every variation in activity is a change of user. The Supreme Court has consistently distinguished a genuine change of purpose from an organic expansion of the same business. In Mohan Lal v. Jai Bhagwan (1988 AIR 1034; (1988) 2 SCC 474), the Court held that adding an allied line of goods to an existing trade does not amount to converting the premises to a different user. The Court emphasised that "the business purposes must be adjudged in the light of the purposes of the Rent Act in question which is to control the eviction of tenants therefrom," and observed that in the era of departmental stores selling a wide range of merchandise, a broad reading of "change of user" would defeat the Act's object. The premises in such cases remain in commercial use; what changes is the basket of goods, not the character of occupation. This functional approach guards tenants against eviction founded on hyper-technical readings of the lease. The dividing line the courts draw is between a change in the kind of use and a change in its degree or content. A tenant who diversifies the merchandise of a shop, or who adds a complementary service to an existing trade, has not altered the purpose of occupation; the premises continue to be used as business premises. By contrast, a tenant who converts the premises to a fundamentally different character of use crosses the line. The enquiry is thus qualitative, not arithmetical, and asks whether an ordinary person would say the premises are now being used for a different purpose. Read this way, clause (c) targets genuine substitution of purpose, not the natural evolution of a lawful business, and the Mohan Lal principle prevents the ground from being weaponised against ordinary commercial growth.

Residential to commercial: the clearest breach

The paradigm case of change of user is the conversion of premises let for residence into business or commercial premises. Here the deviation is in the very character of occupation, not merely in its content, and courts treat it as a textbook breach of Section 108(o) of the Transfer of Property Act and of clause (c). The Transfer of Property Act jurisprudence is settled that the mere act of changing the purpose of user, even where it neither destroys nor permanently injures the property, breaches the lessee's obligation under Section 108(o). Under the Karnataka Rent Act, however, even this clear deviation must still pass through the consent and notice filters of clause (c): the landlord must show absence of written consent and must have served the curative notice. The substantive breach and the procedural safeguards are cumulative, not alternative.

Identifying the purpose of letting

Because clause (c) turns on deviation from the purpose for which premises were let, fixing that purpose is the first factual battleground. The purpose may be express, recorded in the rent deed, or implied from the nature of the premises, the conduct of the parties, and the surrounding circumstances. Where the lease is silent, courts infer purpose from how the premises were used at the inception of the tenancy and from their physical configuration. A residential flat let to a family carries an implied residential purpose; a shop in a commercial complex carries an implied business purpose. The narrower and more specific the recorded purpose, the easier it is for a landlord to prove deviation, which is why carefully drafted user clauses matter. This enquiry dovetails with the statutory definitions of "premises," since the Act's application to a given building shapes what user is permissible.

Burden of proof and the landlord's onus

The onus of establishing every ingredient of clause (c) rests on the landlord, consistent with the general rule that a landlord seeking eviction must prove the statutory ground he invokes. He must establish, first, the purpose for which the premises were let; second, that the tenant has in fact used them for a different purpose; third, that this was done without his written consent; and fourth, compliance with the mandatory notice. Failure on any limb defeats the petition. The protective architecture of Section 27, which begins by forbidding eviction "save as" on the enumerated grounds, reinforces that the burden never shifts to the tenant to justify his occupation; it is for the landlord to make out the breach. This allocation aligns the change-of-user ground with the Act's wider treatment of the landlord-tenant balance, including the regime for standard rent determination and revision.

Although clause (c) speaks of consent "in writing," the landlord's conduct still matters. A landlord who has long known of and accepted a changed user, accepting rent without protest while the altered use continues, may find a court reluctant to grant eviction, on principles of waiver and acquiescence. The statutory requirement of written consent protects tenants by demanding clear authorisation; it does not licence a landlord to lie in wait, tolerate a changed user for years, and then spring an eviction. Equally, a single isolated or temporary act, like the short-lived television sales in Gurdial Batra, is unlikely to be treated as an established change of user, because the ground contemplates a settled deviation rather than a fleeting one. Courts read the clause purposively, asking whether the tenant has genuinely converted the premises to a different use to the landlord's prejudice.

Prejudice and the protective purpose of the ground

A recurring theme in the case law is that the change-of-user restriction exists to protect the landlord's legitimate interest in the property, not to trap tenants on technicalities. In Gurdial Batra the Supreme Court treated the restriction as "one to protect the interests of the landlord," and weighed the temporary nature of the impugned activity and the absence of demonstrated harm. While clause (c) does not expressly require proof of prejudice, the prejudice enquiry colours how courts decide whether a deviation is substantial enough to count as a change of user at all. A change that leaves the premises in the same broad character and causes the landlord no detriment is unlikely to be visited with the drastic consequence of eviction. This proportionate approach is consistent with the Act's general scheme on lawful increases and other landlord remedies, which balance ownership rights against security of tenure.

Practical checklist for landlords and tenants

For a landlord, a successful change-of-user eviction under Section 27(2)(c) requires a clear record of the let purpose, evidence of a genuine and substantial deviation, proof that no written consent was given, and strict compliance with the registered-post notice and one-month cure window. Skipping the notice is fatal. For a tenant, the defences are correspondingly clear: produce written consent if any exists; point to a permissive or silent user clause; characterise the activity as an allied expansion rather than a change, invoking Mohan Lal; show the deviation was temporary or caused no prejudice, invoking Gurdial Batra; or, most simply, comply with the notice within the month and revert to the original user. Both sides should remember that change of user is only one of the enumerated grounds and must be pleaded and proved on its own terms, separate from the other heads in the eviction grounds framework.

Frequently asked questions

Which section of the Karnataka Rent Act, 1999 deals with change of user?

Change of user is a ground for eviction under Section 27(2)(c), which permits recovery of possession where the tenant has used the premises for a purpose other than that for which they were let, without the landlord's written consent.

Must the landlord give notice before suing for change of user?

Yes. The proviso to clause (c) bars any application unless the landlord has first served, by registered post and personally, a notice requiring the tenant to stop the misuse, and the tenant has failed or refused to comply within one month of service.

Does oral consent by the landlord protect the tenant?

Clause (c) speaks of consent "in writing," so written authorisation is the clearest defence. However, prolonged acquiescence, such as accepting rent for years with knowledge of the changed user, may still defeat eviction on waiver principles.

Is adding a new line of goods a change of user?

Generally no. In Mohan Lal v. Jai Bhagwan the Supreme Court held that adding an allied business does not amount to change of user, since the purpose must be judged in light of the Rent Act's protective object and the expanding concept of business.

Did Gurdial Batra establish that any extra business is permissible?

No. In Gurdial Batra v. Raj Kumar Jain the Court relied on the rent note containing no restriction and on the temporary, non-prejudicial nature of the television sales. Where the lease restricts user or the deviation is substantial and harmful, the result can differ.

Who must prove a change of user?

The landlord. He must establish the let purpose, the deviation to a different purpose, the absence of his written consent, and compliance with the mandatory notice. Failure on any one limb defeats the eviction petition.
