Party wall notices when the neighbour is a landlord, tenant or council

Serving the wrong person is one of the commonest causes of invalid notices. Where a property is rented, owned by a council or housing association, or in multiple ownership, identifying the “owner” for the Act takes care.

Who is an owner?

Section 20 defines “owner” to include:

• A person in receipt of, or entitled to receive, the whole or part of the rents or profits of land. That includes a landlord, and in some cases a head lessee receiving rent from a sub-tenant.
• A person in possession of land, other than as a mortgagee, a tenant from year to year or for a lesser term, or a tenant at will. That includes an owner-occupier and a long leaseholder.
• A purchaser of an interest in land under a contract for purchase or an agreement for a lease (other than one for a tenancy from year to year or less).

A property can therefore have several owners at once, for example a freeholder, a long leaseholder, and a buyer who has exchanged contracts. Each is an adjoining owner entitled to notice.

Landlords and tenants

Tenants are not powerless. As “adjoining occupiers” they benefit from the duty not to cause unnecessary inconvenience (s.7(1)), compensation for loss or damage (s.7(2)), protection where premises are laid open (s.7(3)) and 14 days’ notice of entry (s.8(3)-(4)). Landlords should tell tenants about notices and arrange access for Schedules of Condition. Tenants’ belongings may need recording separately.

Serving notice on a landlord

Landlords often live elsewhere. Section 15 allows posting to their usual or last-known residence or place of business (s.15(1)(b)), or service on a company at its registered office (s.15(1)(c)). Check the title register for the registered owner and any address for service. If a letting agent manages the property, confirm whether they are authorised to accept notices; if not, serve the landlord directly as well. Where you cannot trace the owner, section 15(2) allows a notice addressed to “the owner” of the premises, naming them, to be delivered to someone there or fixed to a conspicuous part of the premises.

Councils and housing associations

Local authorities and registered housing providers are owners under the Act and are served like any other owner. Points to note:

• Serve the correct legal entity at its principal office, ideally marked for the attention of the property or estates team.
• Where the neighbour is a council tenant, the council is the owner and the tenant is the occupier.
• Where a council house has been bought under right to buy, the buyer is the owner.
• Councils and housing associations often appoint their own surveyor rather than consenting.
• If the council is itself a party to the dispute and a third surveyor must be selected by default, the Secretary of State selects instead of the council’s appointing officer (s.10(8)(b)).

The Crown and exceptions

Section 19 applies the Act to land with an interest belonging to the Crown or a government department, and to certain Duchy of Lancaster and Duchy of Cornwall land that is vested but not occupied. Section 18 excludes land in inner London in which the Inner Temple, Middle Temple, Lincoln’s Inn or Gray’s Inn has an interest. Some major infrastructure Acts also modify the Act along their routes.

Commercial neighbours

Shops, offices and pubs next door often involve a freeholder, a leaseholder and sometimes a sub-tenant. Serve the freeholder and any leaseholder with more than a year’s term. Business occupiers will want working hours and access arrangements that protect trading.

If you are the landlord doing the work

A landlord carrying out work to their let property is the building owner, and must serve notices on adjoining owners in the normal way. Check the tenancy agreement for access and quiet enjoyment, and tell your tenant what is happening.

Checklist

• Obtain title registers for every adjoining property.
• Identify freeholders, long leaseholders and buyers under contract.
• Serve each owner by a valid section 15 method; keep proof.
• Inform occupiers; serve 14 days’ notice of entry where needed.
• For councils and housing associations, serve the legal entity at its principal office.

Worked example (illustrative)

Illustrative only. Not a real case.

A homeowner’s attached neighbour is a house let to tenants on an assured shorthold tenancy through a letting agent. The title register shows a landlord living abroad, with a UK address for service. The notice is posted to that address and copied to the agent, and the tenants are told about the works and asked to allow access for the Schedule of Condition. The landlord appoints a surveyor by email. During the work, 14 days’ notice of entry for scaffolding is given to both the landlord and the tenants, and a tenant’s damaged garden furniture is compensated under section 7(2).

Leaseholds, head leases and sub-lets

Ownership chains can be layered. A typical converted house may have a freeholder, a long leaseholder of each flat, and a short-term tenant of one of those flats. For a section 3 notice affecting the ground-floor flat, the freeholder and the leaseholder of that flat are both owners; the tenant is an occupier. Where a long leaseholder sub-lets on a long lease, the sub-lessee in possession may also be an owner. If in doubt, serve every person who appears to fall within the section 20 definition; serving an extra person does no harm, while missing an owner can invalidate the process as against them.

When the owner is a company or trust

• Serve a company at its registered or principal office, addressed to the secretary or clerk (s.15(1)(c)).
• Where property is held by trustees, name and serve all the trustees shown on the register.
• For a property in probate, the personal representatives are normally the owners for practical purposes; take advice if the position is unclear.

Tips for adjoining landlords

• Respond within 14 days, or a dispute is deemed.
• Arrange tenant access for the Schedule of Condition, and ask the surveyor to record any tenant-owned items that may be affected.
• Pass on notices of entry to your tenants promptly.
• Remember the building owner normally pays your surveyor’s reasonable fees (s.10(13)).

If the owner cannot be found

Empty and neglected properties are a common problem. Check the title register for an address for service, try any agent or previous address, and keep records of your attempts. Section 15(2) then allows a notice addressed to “the owner” of the premises, naming them, to be delivered to a person there or fixed to a conspicuous part of the premises. If no response follows, the section 10(4) procedure can be used to appoint a surveyor on the owner’s behalf.

Keep copies of every attempt to contact the owner. If the owner later surfaces and challenges the process, that record shows the notice and appointment were properly made.
