Can you build a catio in a rented home? Landlord rules for 2026
Pet permission and alteration permission are two different things
The Renters' Rights Act changes in England gave tenants a right to request a pet from 1 May 2026. The landlord must normally reply in writing within 28 days and cannot unreasonably refuse. That is a big step forward for cat owners who rent, but it is about keeping the animal, not about building anything.
A catio usually involves screws into walls, posts set into the ground, brackets on fences or a cat flap cut into a door or window. Almost every tenancy agreement says you need the landlord's consent before making alterations, and you should get that consent separately and in writing. Asking for both at the same time, with a clear plan, tends to get the best result.
Which types of enclosure landlords are most likely to accept
| Type of enclosure | Fixings needed | Typical landlord view |
|---|---|---|
| Freestanding walk-in run on slabs | None, sits on its own frame | Usually accepted, nothing to make good |
| Window box on existing window | A few screws into the frame or reveal | Often accepted with a written plan |
| Lean-to catio against the house | Wall plates and ground posts | Needs a firm agreement on removal |
| Cat-proof fence toppers | Brackets on fence posts | Depends on who owns the fence |
| Cat flap through door or glazing | Permanent cut or new glass unit | Least likely, often refused |
If you expect to move within a couple of years, a freestanding or modular enclosure is the safest choice, because it can be dismantled and taken with you.
How to ask your landlord for consent
- Put the request in writing, by email or letter, so there is a record
- Describe the enclosure in plain terms: size, materials, where it will go and how it is fixed
- Include a sketch or photo of a similar design
- Say exactly how it will be removed and the area made good at the end of the tenancy
- Offer to use existing fixing points or freestanding options wherever possible
- Ask for the consent, and any conditions, to be confirmed in writing
Landlords mainly worry about damage to walls, drainage, damp, fences shared with neighbours and the cost of putting things back. Addressing those points up front removes most of the reasons to say no.
Designs that leave no trace
Many rented gardens can take a good-sized enclosure without a single hole in the house. A walk-in run on paving slabs, weighted or anchored with ground screws rather than concrete, can be secured against wind and still lifted out in an afternoon. Modular mesh panels bolted to each other, not to the house, give flexibility if you move to a property with a different layout.
Access is the harder part. Instead of a cat flap, some tenants use a short mesh tunnel from an existing window that opens fully, or simply carry the cat out to the enclosure at set times. Both avoid permanent changes to doors and glazing.
Flats, shared gardens and blocks
If you rent a flat, the landlord may themselves need permission from the freeholder or managing agent before agreeing to anything on a balcony, terrace or communal garden. Many leases restrict items on balconies, and some blocks ban combustible materials there for fire safety reasons. Ask the landlord to check the lease before you buy anything.
Shared gardens are rarely suitable for a fixed catio because other residents have rights over the space. A window box or balcony enclosure within your own demise is usually more realistic.
What to agree before you move out
- Who removes the enclosure and when
- What making good means: filling holes, reseeding grass, replacing fence brackets
- Whether the landlord would like to keep it for future tenants
- Photos of the area before installation, kept with your tenancy paperwork
Agreeing these points at the start avoids disputes over the deposit at the end of the tenancy. Some landlords are happy to keep a well-built enclosure because it makes the property more attractive to the growing number of tenants with cats.
A note for landlords considering a request
If you let property, a tenant asking for a catio is usually a sign of a responsible owner who wants to keep a cat safe and stop it damaging the house through boredom. A contained cat is also less likely to cause complaints from neighbours about fouling in their gardens or fights with their own pets. It is worth weighing those benefits against the modest risk of a few fixing holes.
- Ask for a plan and photos before agreeing
- Set clear conditions on fixings, location and removal
- Prefer freestanding or modular designs for short lets
- Consider keeping a quality enclosure as a feature for future tenants
- Record the condition of the area with dated photos
- Confirm everything in writing alongside the tenancy
Refusing every alteration outright can leave a tenant with a cat that is either confined indoors or roaming near a road, neither of which helps the property. A reasonable written agreement usually protects both sides.
Frequently asked questions
Can my landlord refuse a catio if they have agreed to my cat?
Yes. Agreeing to the cat does not oblige the landlord to allow alterations. Most tenancies require consent for changes to the building or garden, and a landlord can reasonably refuse structures that would damage the property. A freestanding design with no fixings is much harder to object to, so offer that option if a fixed catio is turned down.
Do the 2026 pet rules apply in Scotland and Wales?
The right to request a pet introduced on 1 May 2026 applies to most private tenancies in England. Scotland and Wales have their own tenancy law and different rules, so check the current guidance for your nation or ask your letting agent. In every part of the UK, alterations still normally need written consent from the landlord.
Is a freestanding catio safe in strong wind?
It can be, as long as it is anchored properly. Ground screws, weighted base rails or bolting the frame to heavy slabs all stop a run moving in a gale without permanent concrete footings. Tall, lightweight runs with solid roof panels catch the most wind, so mesh roofs or a lower profile are better in exposed gardens.
