Home > Blog > Short-Term Stay vs Long-Term Stay: 7 Things You Need to Check Before Your Next Guest Arrives
Letting your property on Airbnb or as a holiday rental? The wrong planning use class could trigger enforcement action, fines, and force you to stop taking bookings. Most property owners don't realize they need planning permission until it's too late.
Is Your Short-Term Let Legal?
Quick answer - it depends on your use:
| Use Class | Property Type | Planning Permission? |
| C3 |
Main home + occasional letting |
✅ No (up to 90 nights/year in London |
| C5 |
Dedicated short-term rental |
❌ Yes – required |
| C1 |
Hotel/commercial guesthouse |
❌ Yes – always required |
“London: short-term lets are generally restricted to 90 nights per calendar year unless you have planning permission; council tax liability also matters—check your borough rules.”
Not sure which category you fall into? Getting this wrong can result in enforcement action, fines, and forced closure of your rental. Here are the 7 essential checks every property owner must complete
Planning use classes categorise how land and buildings are used, allowing local authorities to manage development and changes of use. They are set out in the Town and Country Planning (Use Classes) Order 1987 (as amended).
In simple terms, if a building changes from one use class to another, planning permission is often required. If it remains within the same class, permission is not usually needed.
Use Class C3 applies to dwellinghouses where people live as their main residence. This includes houses and flats occupied by individuals, families or small households on a long-term basis.
C3 typically covers:
This is the most common use class for long-term stays, where occupants treat the property as their primary home.
Using a property for residential purposes under C3 does not normally require planning permission. However, planning permission may be required where there is a material change in how the property functions, for example through subdivision, intensification, or conversion to a different use class.
Use Class C1 applies to hotels, guest houses, boarding houses and similar forms of accommodation where visitors stay on a short-term basis.
C1 accommodation is characterised by:
Changing a property from C3 residential use to C1 hotel or guesthouse use almost always requires planning permission. Local authorities assess impacts such as noise, servicing, parking and the effect on neighbouring residential amenity.
Short-term lets have historically sat between residential and commercial uses, creating uncertainty for property owners.
In some cases, short-term letting of a residential property can still fall within Use Class C3, particularly where:
In London, a residential property can generally be let for up to 90 nights per calendar year without planning permission, provided it remains a dwellinghouse.
Outside London, there is no fixed national limit, but the principle of material change of use still applies.
The proposed Use Class C5 has been introduced to address long-standing uncertainty around properties used primarily for short-term accommodation.
C5 is designed for properties used almost exclusively for short-term stays, such as:
The key test is how the property operates in reality. If it functions more like commercial accommodation than a home, it is likely to fall within C5 rather than C3.
There are several common scenarios where planning advice is essential:
Homeowners who let their main residence for short periods may remain within C3, provided thresholds and local policies are not breached.
Where a property is purchased solely for short-term letting, this is one of the clearest cases where C5 is likely to apply and planning permission may be required.
Buildings with a mix of long-term residential units and short-term lets are often scrutinised due to concerns around noise, security and loss of residential character.
Serviced apartments are frequently misunderstood. Depending on how they operate, they may fall within C1 or C5, even without traditional hotel services.
C2 covers residential care homes, nursing homes and similar accommodation where care is provided. Moving between C3 and C2 often requires planning permission and careful justification.
Some accommodation uses fall outside standard use classes and are treated as sui generis, meaning any change of use usually requires planning permission.
Short-term accommodation is an area of increasing enforcement and policy focus. Many property owners assume that short-term letting is automatically permitted, only to discover later that their use requires consent.
Each case depends on:
There is no single rule that applies to every situation.
At 4D Planning, we are regularly instructed to advise on whether a property falls within C3, C5 or C1, and whether planning permission or a Certificate of Lawfulness is required. We act for homeowners, landlords, developers and investors across London and England.
Our experience includes:
By understanding how local authorities interpret accommodation use in practice, we provide clarity and reduce risk before issues arise.
The distinction between short-term and long-term accommodation in planning terms is no longer straightforward. With the introduction of Use Class C5, property owners must be more careful than ever to ensure their use is lawful.
If you are unsure how your property is classified, or whether planning permission is required, early professional advice can save significant time, cost and stress. 4D Planning are well placed to guide you through this process and act as a long-term planning partner. Contact Us here.
