Licensing schemes in force
Mandatory HMO licensing
Applies district-wide to HMOs with 5+ occupants forming 2+ households. National scheme under the Housing Act 2004, Part 2. It has no end date and never lapses.
Additional licensing
Arun runs an additional licensing scheme covering smaller HMOs. Check whether your property falls inside the designated area.

Article 4 direction
An Article 4 direction removes permitted development rights for HMO conversion in part or all of Arun. Converting a family home (C3) to a small HMO (C4) needs planning permission inside the direction area. Large HMOs of 7+ occupants are sui generis and always need permission.

Arun HMO questions, answered plainly
Do I need an HMO licence in Arun?+
You need a mandatory HMO licence if your Arun property houses 5 or more people from 2 or more households sharing facilities. This is the England-wide mandatory rule under the Housing Act 2004. Arun also runs an additional licensing scheme, so smaller HMOs may need a licence too. Check the scheme boundary before assuming a 3–4 person HMO is exempt. Confirm the current position with the council before accepting tenants.
How much does an HMO licence cost in Arun?+
A new mandatory HMO licence in Arun costs £1,834, and renewal costs £1,834. The licence runs for 5 years. Fees change with council budgets, so confirm before applying.
Does Arun have an Article 4 direction for HMOs?+
Yes. An Article 4 direction is in force in Arun (or part of it), which means planning permission is required to convert a family home (C3) to a small HMO (C4, up to 6 occupants). Check the exact boundary with the planning department, because directions often cover specific wards rather than the whole district.

National minimums apply: 6.51m² for one adult, 10.22m² for two adults, and 4.64m² for a child under 10. Rooms under 4.64m² cannot be used for sleeping. Arun may also apply local amenity standards for kitchens and bathrooms, so check before letting.
What happens if I run an unlicensed HMO in Arun?+
Operating a licensable HMO without a licence is an offence under section 72 of the Housing Act 2004. The council can prosecute (unlimited fine) or issue a civil penalty of up to £30,000 per offence. Tenants can claim back up to 12 months of rent through a Rent Repayment Order, and Section 21 notices are invalid while the property is unlicensed.
