How the Rental Housing Act Governs Deposits in South Africa

The Rental Housing Act 50 of 1999 (RHA) is the primary legislation governing residential rental deposits in South Africa. Section 5(3) of the Act requires landlords to invest deposits in interest-bearing accounts, with the interest accruing to the tenant's benefit. This is a non-negotiable statutory requirement — lease agreements that purport to allow the landlord to retain interest are unenforceable regardless of what the lease says.

The deposit refund process is governed by the inspection regime in Section 5(4) and (5). The landlord must offer the tenant a joint inspection at move-in and a joint outgoing inspection at move-out. If an outgoing inspection is conducted and damages are found, the landlord may deduct the repair cost from the deposit, refunding the balance within 14 days of the dwelling being restored. If no outgoing inspection is conducted, or no amounts are owed, the landlord cannot make deductions — the full deposit plus interest must be returned within 7 days of the lease ending.

Fair Wear and Tear vs Damage — The Critical Distinction

The most common dispute in SA rental deposit refunds is the boundary between fair wear and tear (not deductible) and actual damage (deductible). Fair wear and tear is the normal deterioration from reasonable use over time — scuff marks on walls, minor carpet wear, faded paint, small nail holes from picture hooks. These are the landlord's cost of doing business and cannot be recovered from the deposit.

Actual damage that can be deducted includes holes in walls, broken doors or windows, stained carpets, burns, broken fixtures, and damage caused by negligence. The landlord must quantify the damage with quotes or invoices from contractors. Betterment is not recoverable — if an 8-year-old carpet needs replacing, the landlord can only recover the depreciated value, not the full replacement cost of new carpet.

Landlords who attempt to deduct for fair wear and tear or who cannot produce itemised invoices for claimed damages are in breach of the Act. The Rental Housing Tribunal consistently rules against landlords who cannot substantiate deductions with documentary evidence.

Section 5(3) Deposit Refund Timelines: 7 Days vs 14 Days

Section 5(3) of the Rental Housing Act sets separate deadlines depending on what happens at lease end. The table below maps each scenario to its deadline — always count from the date the lease actually terminates, not the date the tenant physically vacates if that differs.

The Act requires a joint outgoing inspection — the landlord and tenant inspect the dwelling together, ideally in the days immediately around the lease ending, and record its condition in writing. If the tenant is available and no defects are found, no deductions may be made and the 7-day rule applies. For the full statutory text, see the Rental Housing Act 50 of 1999 on SAFLII.

Failure to refund within the applicable deadline constitutes a breach of the Act. Tenants have several remedies: approaching the Rental Housing Tribunal (free, decisions enforceable like court orders), sending a formal letter of demand, or issuing summons in the Small Claims Court for amounts up to R20,000. The Tribunal is the recommended first step — it is free, relatively quick, and its decisions have full legal force. If the landlord is uncontactable or refuses to engage, the Small Claims Court is the next practical step.

Deposit Management Best Practice for SA Landlords

SA landlords who manage deposits correctly protect themselves from Tribunal complaints and ensure the refund process is smooth. Best practice includes opening a dedicated savings or money market account per property (or per tenancy), documenting the account details in the lease, providing the tenant with bank confirmation that the deposit is invested, and sharing annual bank statements showing interest accrued.

At move-in and move-out, conduct joint inspections with the tenant and document the condition in writing, signed by both parties. A detailed photographic record at both inspections is essential. If deductions are needed, provide a written schedule of deductions with supporting invoices within the 14-day period. Landlords who follow this process consistently are rarely troubled by Tribunal complaints, and when they are, they have documentary evidence to defend their position. The RHA specifically requires that deposit interest be calculated at the rate applicable to a savings account with the bank where the deposit is held — not a current account rate.

Manual Calculation — A Deposit Interest Example

Say a tenant pays a R17,000 deposit (2 months' rent on a R8,500/month lease) at the start of a 12-month lease, held at a market interest rate of approximately 7.00% per year. Using simple interest as a conservative estimate, R17,000 × 7.00% × (12 ÷ 12) = R1,190 in interest accrued over the year. This interest belongs to the tenant, not the landlord, and must be added to the refund unless lawful deductions for damage beyond fair wear and tear apply. A landlord who fails to pay this interest, or who deducts for normal wear and tear, risks a Rental Housing Tribunal ruling against them. Keeping the deposit in a dedicated, clearly documented interest-bearing account from day one avoids disputes over how much interest has actually accrued by the time the tenant moves out.
