Can I Increase Rent, and If So, by How Much and How Often?

For landlords in South Africa, rent increases are a regular part of property management, but they must be handled carefully to remain legal, fair, and sustainable.

Increasing rent without following the correct process can lead to disputes, tenant dissatisfaction, and even legal consequences.

This guide explains when and how landlords can increase rent in South Africa, what constitutes reasonable rent increases, how often increases can be made, and what steps to take to avoid disputes.

Understanding the Legal Framework for Rent Increases

In South Africa, rent increases are regulated by a combination of lease agreements, common law, and consumer protection legislation, including the Rental Housing Act and the Consumer Protection Act (CPA).

These laws do not set a specific limit on how much you can increase rent, but they do require that:

• Any increase must be reasonable and fair.
• The landlord must give proper written notice before applying the increase.
• The increase must comply with the terms of the signed lease agreement.

If a tenant believes the increase is excessive or unreasonable, they can approach the Rental Housing Tribunal for assistance.

How Often Can You Increase Rent?

In most cases, rent can only be increased once every 12 months during an ongoing tenancy.

• Fixed-term lease: Rent can usually only be increased at the end of the lease period, unless the lease explicitly allows for mid-term increases.
• Month-to-month lease: Rent can be increased with at least one calendar month’s written notice.
• Yearly lease renewal: If the tenant renews for another year, the new rent amount must be agreed upon before signing the renewal.

How Much Can You Increase Rent By?

While South African law does not set a strict percentage limit, increases must be reasonable and market-related.

Standard guidelines followed by many landlords include:

• Inflation-linked increases – Often 5–8% per year, depending on economic conditions.
• Market-related increases – Aligning with average rental prices for similar properties in the area.
• Cost-related increases – Adjusting rent to cover rising property expenses such as rates, utilities, and maintenance.

A rent hike far above market rates could be seen as unreasonable and may be challenged by the tenant.

When to Increase Rent

The best time to increase rent depends on your lease structure and local rental demand:

• At lease renewal – The most common and least disputed time to increase rent.
• When market conditions change, if local rental rates rise significantly, an adjustment may be warranted.
• After significant property improvements, renovations that enhance the property’s value may justify a higher rent.

Notice Requirements for Rent Increases

Proper written notice is essential to remain compliant with South African rental laws.

• For fixed-term leases under the CPA, A landlord must give at least 20 business days’ notice before the increase takes effect.
• For month-to-month leases – A whole calendar month’s written notice is required.
• The notice must clearly state:
  • The current rent
  • The new rent amount
  • The effective date of the increase
  • The reason for the rise (optional, but recommended to maintain good tenant relations)

Factors to Consider Before Increasing Rent

Before deciding on the increase amount, landlords should weigh the following:

1. Local market conditions – If similar properties in your area are renting for less, tenants may choose to move.
2. Tenant reliability – A good tenant who pays on time and takes care of the property may be worth keeping at a slightly lower increase.
3. Property maintenance costs – If running costs have gone up, it’s fair to factor these into the rent adjustment.
4. Economic climate – In times of financial hardship, smaller increases may help retain tenants.

How to Calculate a Fair Rent Increase

To calculate the rise that’s reasonable and market-aligned:

• Research comparable rental prices in your area.
• Consider CPI (Consumer Price Index) inflation rates.
• Factor in property improvements or added facilities.
• Ensure the new rent won’t drive away good tenants unnecessarily.

Example:

If your property is renting for R8,000 per month and CPI inflation is 6%, an inflation-linked increase would be:

R8,000 × 6% = R480 increase → New rent = R8,480 per month.

How to Communicate a Rent Increase

How you notify tenants is just as important as the amount you increase. A well-written, respectful notice can help avoid disputes.

Communication tips:

• Give sufficient notice.
• Clearly state the new rental amount and the effective date.
• Explain the reason for the increase (e.g., rising property costs, market adjustments, or improvements).
• Offer to discuss any concerns before the new rent applies.

Disputes Over Rent Increases

If a tenant feels an increase is unfair, they can:

• Negotiate directly with the landlord.
• File a complaint with the Rental Housing Tribunal.
• Seek legal advice if they believe the increase violates the lease or the law.

The Tribunal can order a landlord to reduce or withdraw an unreasonable increase.

Best Practices for Landlords

To avoid disputes and keep tenants happy:

• Review rent annually – Avoid sudden, significant increases.
• Stay informed on market trends – Regularly research comparable properties.
• Keep detailed records – Document all communications and reasons for increases.
• Be transparent – Tenants appreciate honesty about why rent is going up.

• Rent is usually increased annually and should be based on inflation, market rates, or increased property costs.
