Knysna Valuation Roll: What Every Homeowner Must Check Before 8 June 2026

6 min read

TL;DR – Too Long, Didn’t Read

The Knysna Supplementary Valuation Roll is open 7 May – 8 June 2026. Here’s what matters:

• Your property has three different values – municipal, market, and replacement cost. They are not the same.
• Your insurance must be based on replacement cost – not the municipal or market value.
• During this window, you can inspect your valuation, compare it to similar homes, and object if it’s wrong – but you must use the official form and do it before 8 June. No extensions.
• If your value is too high, you’re overpaying rates. If it’s too low, your insurer can reduce your claim payout.
• Use this window as a checkpoint. Check your valuation. Check your insurance cover. If you’re unsure about either, talk to us.

The Knysna Municipality has quietly opened its Supplementary Valuation Roll for inspection.

Most homeowners will scroll past this, assume it doesn’t affect them, and move on.

That’s a mistake.

This number sits quietly in a municipal database but it has a direct line to your rates bill. And if you’re not careful, it has a way of quietly undermining your insurance cover too. For South African homeowners, understanding home insurance replacement cost is one of the most important, and most overlooked, parts of owning property.

You have from 7 May to 8 June 2026 to check it, question it, and if necessary, challenge it. After that window closes, the opportunity is gone until the next valuation cycle.

Here’s everything you need to know.

Three Numbers, Three Very Different Meanings

When someone talks about your “property value,” they could mean at least three different things and confusing them is where most homeowners get into trouble.

Municipal Valuation

This is the number the Knysna Municipality uses to calculate your rates and taxes. It’s produced through mass valuation models, essentially a system that estimates property values in bulk across the entire municipal area.

Because it’s built for scale, not precision, it’s often inconsistent. Two similar homes on the same street can carry meaningfully different valuations. It’s a taxation tool, not a reflection of your property’s true condition or unique features.

What it’s used for: Calculating how much you pay in rates.
What it’s not: An accurate picture of your property.

Market Value

Market value is what your home would sell for today, on the open market, to a willing buyer. It’s shaped by demand, comparable sales, timing, and a fair bit of negotiation.

Market value moves. It was different two years ago, it’ll be different in two years’ time, and it can shift meaningfully depending on what’s happening in the broader Knysna property market.

What it’s used for: Selling your home.
What it’s not: A basis for your insurance.

Replacement Cost – The Home Insurance Value That Actually Matters

This is the number that doesn’t get talked about nearly enough.

Replacement cost is what it would cost to rebuild your home from scratch if it were completely destroyed, think fire, flood, or major structural damage. That means demolition and debris removal, materials, labour, architectural and engineering fees. Everything except the land.

Here’s the part that surprises most people: replacement cost is often higher than market value. Building a home today costs more than it did when your home was first built. Material costs and labour rates increase every year. The land you’re sitting on may have kept pace with the market but rebuilding the structure is a different calculation entirely.

What it’s used for: Calculating the correct sum insured on your home insurance policy.
What it must be: The basis of your insurance.

What the Municipality Is Offering You Right Now

From 7 May to 8 June 2026, every Knysna property owner has the right to:

• Inspect their property’s municipal valuation
• Compare it to similar properties in their area
• Lodge a formal objection if the valuation appears incorrect

This is your window. Once it closes on 8 June 2026, the current valuations are locked in until the next supplementary or general valuation process.

Most people don’t use it. The ones who do are the ones who catch errors before they turn into years of overpaying.

The Rules Most People Don’t Know

If you do find a problem and want to object, there are rules and they’re non-negotiable.

You cannot object to the valuation roll as a whole. You must object to a specific property, your own.

You must use the official municipal objection form. A letter or email won’t be accepted.

Your objection must be submitted on or before 8 June 2026. There are no extensions.

Miss any one of these, and your objection won’t be heard. It’s not a forgiving process, which is exactly why it’s worth getting right the first time.

The Dangerous Assumption

The most common mistake Knysna homeowners make is assuming their municipal valuation is “roughly right.”

Sometimes it is. Often it isn’t.

Municipal valuations are modelled estimates. They don’t account for the specific condition of your home, recent renovations, or how your property compares to its immediate neighbours. The model works at a municipal scale, your home is one data point among thousands.

If your valuation is too high: You may be overpaying rates every year and have been for some time.

If your valuation is too low: The instinct is to feel relieved. Don’t be. A low municipal valuation can create a false sense of comfort about your insurance cover especially if you’ve ever used it as a rough reference point for the value of your property.

Home Insurance Replacement Cost: Why It Matters More Than Your Municipal Value

Your home insurance cover is not, and should never be, based on your municipal valuation.

It should not be based on your market value either.

The correct basis for your sum insured is replacement cost. If your policy is built on the wrong number, your insurer is entitled to apply what’s known as average in the event of a claim. Average means they pay out a proportionally reduced amount, not the full value of your loss.

In plain terms: if you’re underinsured by 30%, your insurer may only pay 70% of your claim. On a major loss, that gap can be significant.

Municipal valuations move. Building costs move faster. The only way to know whether your home is correctly insured is to have the replacement cost independently assessed, not assumed from a number produced by a municipal model.

What to Do Before 8 June 2026

Use this window as a property checkpoint. It takes less time than most people think.

Step 1: Look up your property on the Knysna Municipal valuation roll.

Step 2: Compare it to similar homes in your street or neighbourhood. Are comparable properties valued higher or lower? Does the number feel out of step with reality?

Step 3: If you believe the valuation is clearly incorrect, either too high or too low, lodge a formal objection on the official municipal form before 8 June.

Step 4: Separately, check that your home insurance sum insured reflects actual replacement cost. If you’re not sure what that number should be, speak to your broker.

The Honest Reality

Municipal valuations are estimates. Market values fluctuate. Building costs climb every year.

No single number gives you the full picture on its own and the number that gets used in a mass valuation model is probably not the number your insurer would use to settle a major claim.

The 7 May to 8 June 2026 window is a prompt. Use it to check in on both your rates and your cover.

If you’d like help understanding whether your valuation looks right, or whether your property is adequately insured, we’re here.
