Deposit, utility and contract protections depend on who you rent from. ExpatGuideAI checks the reviewed OCPB controlled-business scope before applying those rules to a condo, apartment, house or room.
Quick answer
A common rental practice is not automatically a universal legal rule. For the reviewed OCPB protections on deposits, utilities and contract terms, check the operator scope first. The verified values below are shown only from the official-source dataset.

The important scope check
The reviewed OCPB dataset describes the controlled residential-rental business as an operator with at least 3 rental units in total, whether in one building or several. Condominium units are among the listed residential premises.
If you rent one condo directly from a private owner and do not know whether that owner falls within the controlled-business scope, do not automatically apply the controlled-business deposit and utility limits.
When the operator is in scope
Confirm who is offering the property and who will actually sign the lease. Inspect the real unit, fixtures, appliances and obvious damage rather than relying only on listing photos.
Ask what is included in rent, what is billed separately, how electricity and water are calculated, and which building rules matter for your intended use before transferring serious money.
Check the rent amount and due date, deposit and advance amounts, lease term, exit and renewal clauses, inventory or condition record, utilities, parking or common charges, repair responsibility and handover conditions.
If the landlord or operator falls within the supported controlled-business scope, the contract and charges also need to respect the applicable OCPB boundaries shown on this page.
Keep the signed lease and payment evidence, photograph the unit condition where useful, record meter readings and confirm who handles TM30. That residence notification is a separate immigration issue, not a tenant-consumer-rights rule.
Assuming one deposit rule applies to every private condo owner without checking the operator scope.
Not confirming who the real landlord or authorized signer is.
Accepting unclear electricity or water markups without understanding how charges are calculated.
Signing without a clear inventory, handover condition or exit clause.
Confusing condo juristic-person charges with private-landlord charges.
Assuming TM30 is automatically the tenant's legal filing duty.
Common questions
No. The reviewed OCPB controlled-business guidance applies to a residential rental operator with at least 3 rental units in total. A condo can be covered residential property without every private condo owner automatically being an in-scope rental business.
For an operator that falls within the reviewed controlled-business scope, advance rent and security deposit combined may not exceed 3 months of monthly rent.
The currently verified OCPB dataset states 7 days after the lease ends when there is no tenant-caused damage.
Condo vs apartment
OCPB notes that an apartment normally has one owner/operator, while a condominium has co-owners and a condominium juristic person managing common property. That difference can matter when evaluating the basis for charges. This is why ExpatGuideAI asks about the landlord/operator instead of treating every Thailand rental as the same legal setup.
