Home insurance for outbuildings, walls and gates

Does home insurance cover garages, cottages, boundary walls and gates?

Yes, garages, cottages, boundary walls, gates and gate motors are usually covered under buildings insurance, because they form part of the permanent structure of your property. The key is that your buildings sum insured must include the rebuild cost of all these structures, not just the main house. Some items, like electric gate motors, may also have their own sub-limits or conditions, so it's worth checking your wording.

Key takeaways

Outbuildings, walls and gates are generally part of buildings cover.
Your sum insured must include the rebuild cost of all these structures.
Electric gate motors may carry their own sub-limits or surge conditions.
Undeclared or under-valued structures can lead to a reduced payout.
Gradual deterioration and poor maintenance are usually excluded.

What counts as part of your buildings

Buildings insurance covers the permanent structure of your property, and that extends well beyond the four walls of the main house. On a typical South African property, buildings cover usually includes:

Garages and carports
Cottages, granny flats and outbuildings
Boundary walls and fences
Gates and electric gate motors
Swimming pools, paving and permanent fixtures

The common thread is that these are immovable, permanent structures attached to the land. Movable items inside a garage or cottage - tools, furniture, appliances - are contents rather than buildings, so they fall under your contents cover instead. Getting this distinction right helps you insure both correctly.

Why your sum insured must include everything

Here's the pitfall: your buildings sum insured needs to reflect the cost of rebuilding the entire property, not just the house. If you calculate the rebuild value of the main dwelling but forget the cottage, the boundary walls, the paving and the pool, your sum insured will be too low - and the average clause can then reduce even a partial claim in proportion to the under-insurance.

So if a storm demolishes a boundary wall, or a fire damages the garage, the claim relies on your total buildings value being accurate. When you work out your replacement value, walk the whole property and account for every permanent structure. Boundary walls in particular are easy to overlook yet expensive to rebuild across a large plot.

Gates, gate motors and sub-limits

Electric gates and their motors deserve special attention. They're part of the buildings, but because the motor is an electrical component, some policies treat it a little differently. Watch for two things in your wording:

Power-surge conditions - a gate motor can be damaged by an electrical surge, so cover may fall under your power-surge section with its own limit
Sub-limits - some insurers set a specific maximum for gate motors or similar mechanical items

Given how often gate motors fail after surges, particularly with load shedding, it's worth confirming exactly how yours would be covered and up to what amount. Don't assume the full replacement cost is automatically covered without checking.

Common exclusions on walls, gates and outbuildings

Buildings cover responds to sudden, insured events - not to slow decline. Typical exclusions that affect walls, gates and outbuildings include:

Wear, tear and gradual deterioration - a wall that crumbles from age or poor maintenance rather than a specific event
Faulty workmanship or design - damage arising from how something was built
Poor maintenance - rust, rot or cracking left unaddressed over time
Certain ground movement - some subsidence and landslip situations have their own conditions

Keeping walls, gates and outbuildings in good repair matters, because damage traced to neglect is generally not claimable. Maintenance protects both the structure and your ability to claim if a genuine event occurs.

Making sure your outbuildings are properly covered

To avoid gaps, declare all significant structures to your insurer and factor them into your sum insured. Note any cottage or flat that's rented out, since letting can change how it's covered - see buildings insurance for landlords. Check the sub-limits and surge conditions on gate motors, keep everything reasonably maintained, and revisit your total buildings value whenever you add a structure, wall or pool. A quick annual review keeps your cover matched to what's actually standing on your property.

Frequently asked questions

Are boundary walls covered by home insurance?

Usually yes, as part of buildings cover, since walls are permanent structures on your property. But your buildings sum insured must include their rebuild cost, or the average clause could reduce a claim. Damage from gradual deterioration or poor maintenance is generally excluded, so keep walls in good repair.

Is my electric gate motor covered?

Often yes, as part of the buildings, but it may be treated differently because it's an electrical component. Cover for surge damage can fall under your power-surge section with its own limit, and some policies set a sub-limit for gate motors. Check your wording to see how yours is covered and up to what amount.

Does buildings insurance cover a cottage or granny flat?

Generally yes, as an outbuilding forming part of the permanent structure, provided it's included in your buildings sum insured. If the cottage is rented out, letting can change how it's covered, so tell your insurer. Movable items inside it are contents rather than buildings.

Do I need to declare outbuildings to my insurer?

It's wise to. Your buildings sum insured should reflect the rebuild cost of the whole property, including garages, cottages, walls, gates and pools. Undeclared or under-valued structures can leave you under-insured, and the average clause may then reduce even a partial claim.

Are gate motors damaged by power surges covered?

They can be, but cover often falls under your power-surge section rather than general buildings cover, with its own annual limit or conditions. Because gate motors frequently fail after surges linked to load shedding, confirm exactly how yours would be covered before you rely on it.
