Landlords often focus on planning permission, building regulations, contractors and budgets when carrying out works.
But there is another issue that can be easily missed: party wall procedure.
If works affect a shared wall, boundary wall or neighbouring foundations, the landlord may need to serve a party wall notice before work begins.
The key message is simple: landlords should check whether the Party Wall etc. Act 1996 applies before starting works near a neighbouring property.
What is the Party Wall etc. Act 1996?
The Party Wall etc. Act 1996 applies in England and Wales.
It provides a process for dealing with certain works affecting party walls, party structures, boundary walls and excavations near neighbouring buildings.
The Act is designed to reduce disputes by requiring formal notice, giving adjoining owners time to respond and creating a surveyor-led process where agreement is not reached.
It is not the same as planning permission.
It is not the same as building regulations approval.
It is a separate process that may apply even where planning permission is not required.
Why party wall notices matter to landlords
Rental property works often involve older terraced houses, semi-detached homes, flats, extensions, loft conversions, chimney removals, structural alterations and drainage works.
These are exactly the kinds of projects where party wall issues can arise.
If a landlord gets the process wrong, the result may be:
- neighbour disputes;
- work delays;
- contractor disruption;
- surveyor costs;
- legal threats;
- access problems;
- damage claims;
- insurance issues;
- complaints from tenants;
- sale or remortgage complications;
- difficulty proving what condition neighbouring property was in before work began.
A party wall issue can turn a straightforward refurbishment into a costly dispute.
What is a party wall?
A party wall is usually a wall shared by two properties.
Common examples include:
- the wall between two terraced houses;
- the wall between two semi-detached houses;
- a wall separating flats or maisonettes;
- a wall standing astride the boundary;
- a wall forming part of two buildings.
The Act can also apply to party structures, such as floors or ceilings between flats.
It may also apply to party fence walls and certain excavations near neighbouring buildings.
Landlords should not assume the Act only applies to obvious shared walls in terraced houses.
Works that may need notice
Party wall notices may be needed for works such as:
- cutting into a party wall;
- inserting beams into a party wall;
- removing a chimney breast from a party wall;
- making a party wall higher, lower or deeper;
- underpinning a party wall;
- repairing or rebuilding a party wall;
- cutting away projections;
- building a new wall at or astride the boundary;
- excavating near a neighbouring building;
- excavating below neighbouring foundation level;
- loft conversions involving steel beams;
- extensions close to a neighbouring structure;
- basement works;
- structural alterations affecting shared walls.
The detail depends on the specific work and the location of neighbouring buildings.
Planning permission does not remove the need for notice
A landlord may have planning permission and still need to serve a party wall notice.
A landlord may not need planning permission and still need to serve a party wall notice.
The systems are separate.
Planning permission deals with whether the development is acceptable in planning terms.
Building regulations deal with technical construction standards.
Party wall procedure deals with the rights and protections of adjoining owners where certain works affect shared walls, boundaries or nearby structures.
Landlords should check all three where relevant.
Building regulations do not replace party wall procedure
Building regulations approval is also separate.
A building control inspector may approve the technical design, but that does not mean the landlord has complied with the Party Wall etc. Act.
For example, a loft conversion may need building regulations approval and may also require party wall notices because steel beams are being inserted into a party wall.
A rear extension may need building regulations approval and may also require notice because foundations are being excavated near a neighbour’s property.
One approval does not replace the other.
Leasehold landlords and flats
Party wall issues can be particularly important in flats.
Works may affect:
- floors;
- ceilings;
- structural walls;
- shared walls;
- service risers;
- chimney breasts;
- fire separation;
- communal structure;
- adjoining flats above, below or beside the property.
A leasehold landlord may need to consider:
- party wall procedure;
- freeholder consent;
- managing agent approval;
- building regulations;
- lease restrictions;
- lender consent;
- insurance notification;
- tenant disruption;
- access arrangements.
Flats often involve more than one adjoining owner, which can make the process more complicated.
Extensions
Extensions are a common trigger for party wall checks.
Even if the new wall is built entirely on the landlord’s own land, notice may still be required if the work is at the boundary or if foundations are excavated near a neighbour’s building.
Landlords should check:
- where the boundary is;
- whether a new wall is being built at or astride the boundary;
- how close excavation will be to the neighbour’s structure;
- whether excavation goes below the neighbour’s foundation level;
- whether drainage or retaining walls are affected;
- whether access to neighbouring land is needed.
Do not wait until the contractor is ready to dig before checking.
Loft conversions
Loft conversions often involve party wall procedure.
This is because steel beams may be inserted into the shared wall, or works may affect the party structure.
A landlord planning to create a bedroom, office space or additional rental accommodation in a loft should check early.
A loft conversion may also raise planning, building regulations, fire safety, mortgage, insurance and HMO issues.
The party wall process is one part of a wider compliance picture.
Chimney breast removals
Removing a chimney breast from a party wall is a classic party wall issue.
The work may affect the shared wall and the structure of neighbouring property.
Landlords should not treat chimney breast removal as a simple internal alteration.
They may need:
- structural calculations;
- building regulations approval;
- party wall notice;
- contractor method statements;
- leasehold consent where relevant;
- insurance notification;
- clear records.
If the adjoining owner has a chimney breast on the other side, poor work can cause serious problems.
Excavations
Excavation notices can catch landlords by surprise.
The Act may apply where excavation is close to a neighbouring building and deeper than the neighbour’s foundations.
This can arise with:
- extensions;
- drainage works;
- foundations;
- basements;
- underpinning;
- retaining walls;
- new outbuildings;
- structural landscaping;
- major garden works.
Landlords should not assume party wall issues only arise when physically touching the neighbour’s wall.
Excavation near a neighbouring structure can be enough.
Boundary walls
Party wall rules may also apply where a landlord plans to build a wall at or astride the boundary.
This can involve:
- garden walls;
- side extensions;
- boundary structures;
- walls between properties;
- walls enclosing yards;
- walls forming part of an extension.
Boundary positions should be checked carefully.
A small mistake over the boundary line can quickly create a serious dispute.
Serving notice
Where the Act applies, the landlord generally needs to serve the correct notice on the adjoining owner before work begins.
The notice should describe the proposed works and give the adjoining owner time to respond.
Different types of work may require different notices and different notice periods.
Landlords should not rely on informal conversations, text messages or a casual chat over the fence.
A neighbour may be friendly at first but still object later if formal procedure has not been followed.
Who is the adjoining owner?
The adjoining owner may be more than the person living next door.
It may include:
- the freeholder;
- a leaseholder;
- a long leaseholder;
- a neighbouring landlord;
- a management company;
- more than one owner;
- an owner of an adjoining flat;
- an owner above or below in a block.
Landlords should make sure notices are served on the correct parties.
This is especially important in flats and leasehold buildings.
Tenant occupation and party wall works
If the landlord’s property is tenanted, works may also affect the tenant.
Landlords should think about:
- access arrangements;
- noise and dust;
- safety;
- temporary loss of rooms;
- scaffolding;
- reduced facilities;
- contractor access;
- disruption to quiet enjoyment;
- rent disputes;
- complaints;
- insurance conditions;
- health and safety.
Even if the party wall process is handled correctly, the landlord still needs to manage the tenant relationship properly.
What happens after notice is served?
After notice is served, the adjoining owner may consent.
If they consent, the works may proceed in line with the notice, subject to any other permissions required.
If they do not consent, or if they do not respond within the relevant time, a dispute may be deemed to have arisen under the Act.
The matter may then need to be dealt with by surveyors.
Landlords should allow time for this.
Do not serve notice at the last minute and expect works to start immediately.
Party wall surveyors
Where there is a dispute, surveyors may be appointed.
The landlord and adjoining owner may agree on one surveyor, or each may appoint their own surveyor.
The surveyor’s role is not simply to support one side.
The purpose is to deal with the party wall matters under the Act and produce a party wall award where required.
Landlords should budget for surveyor costs.
In many cases, the building owner carrying out the works pays the reasonable costs of the party wall process.
Party wall award
A party wall award may set out:
- the works authorised;
- how works should be carried out;
- working hours;
- access arrangements;
- protective measures;
- surveyor costs;
- procedures if damage occurs;
- drawings or method statements;
- a schedule of condition;
- other relevant conditions.
The award helps define the process and reduce later disputes.
Landlords should keep the award safely with the property records.
Schedule of condition
A schedule of condition records the condition of the adjoining property before works begin.
This may include photographs and written notes.
It can be very important if damage is later alleged.
Without a clear record, it may be harder to show whether cracking, movement or damage existed before the works.
Landlords should treat the schedule of condition as protection, not bureaucracy.
Damage to neighbouring property
If works cause damage to the adjoining property, the landlord may be responsible for putting matters right or compensating the adjoining owner.
This is why proper design, competent contractors, insurance, surveyor involvement and records all matter.
Damage disputes can be expensive and stressful.
A landlord should make sure contractors understand the works, the award and any restrictions.
Access to neighbouring land
The Act may provide rights of access in some circumstances, but this should not be assumed casually.
Access should be handled properly, with notice and care.
Landlords should not allow contractors to enter neighbouring land without proper authority.
Access disputes can quickly escalate.
Starting work too early
Starting work before the party wall process is complete is risky.
A neighbour may seek to stop the work or take action if they believe the Act has been ignored.
Contractors may also be delayed if notice has not been served in time.
Landlords should build party wall timing into the project plan.
It is much easier to deal with notices before contractors are booked, materials are ordered and tenants have been told dates.
Retrospective problems
Party wall procedure is intended to happen before works begin.
If a landlord discovers too late that notice should have been served, the position can become difficult.
The landlord may face neighbour complaints, delays, surveyor involvement, damage claims or legal advice.
Retrospective fixes are rarely as clean as doing the process properly from the start.
Buying a property with past works
Landlords buying investment property should check whether previous works were properly handled.
This is particularly important where there has been:
- loft conversion;
- extension;
- chimney breast removal;
- basement work;
- structural alteration;
- flat conversion;
- excavation close to neighbours;
- removal of internal walls;
- boundary wall construction.
Missing party wall paperwork may not always invalidate the works, but it can raise questions.
It may also make it harder to understand whether adjoining owners were notified and whether disputes were resolved.
Selling or remortgaging
Party wall documents may be requested when selling or remortgaging.
Buyers, solicitors and lenders may ask for:
- party wall notices;
- adjoining owner consents;
- party wall awards;
- schedules of condition;
- surveyor correspondence;
- completion evidence;
- building regulations certificates;
- planning documents.
Landlords should keep the paperwork with the property file.
Do not assume documents will be easy to recreate years later.
Insurance
Landlords should check insurance before starting major works.
Insurance questions may include:
- does the landlord policy cover works?
- does the contractor have public liability insurance?
- is contract works insurance needed?
- are structural works excluded?
- is the property occupied or vacant during works?
- does scaffolding affect cover?
- does the insurer need notification?
- is neighbouring property damage covered?
- are tenant claims covered?
Party wall compliance is not a substitute for insurance, and insurance is not a substitute for party wall compliance.
Contractors
Contractors should be told about any party wall award and restrictions.
They should understand:
- what works are authorised;
- working hours;
- access rules;
- protection requirements;
- method statements;
- neighbour arrangements;
- damage reporting procedures;
- safety requirements;
- tenant access issues.
A good contractor should be comfortable working within formal requirements.
A contractor who dismisses the Act as unnecessary should be treated with caution.
Landlords with portfolios
Portfolio landlords should have a simple party wall screening process before works begin.
For each project, ask:
- is the property attached?
- is there a shared wall?
- are works near a boundary?
- are foundations being excavated?
- is a chimney breast being removed?
- are beams being inserted?
- is a loft conversion planned?
- is the property a flat?
- are there adjoining owners above, below or beside?
- could neighbouring foundations be affected?
This helps identify issues early.
Common landlord mistakes
1. Assuming planning permission is enough
Party wall procedure is separate from planning.
2. Serving notice too late
The process should be built into the project timetable.
3. Relying on informal neighbour agreement
Formal notice may still be needed.
4. Forgetting flats above or below
Party structures can include floors and ceilings.
5. Ignoring excavations
The Act may apply even where no shared wall is being touched.
6. Not keeping paperwork
Notices, consents and awards should be stored safely.
7. Letting contractors start before the process is complete
This can create disputes and delay.
Practical checklist for landlords
Before starting works, landlords should ask:
- does the Party Wall etc. Act apply?
- is there a shared wall or party structure?
- are works at or near the boundary?
- will excavation be close to a neighbouring building?
- will works go below neighbouring foundation level?
- is a loft conversion planned?
- are beams being inserted?
- is a chimney breast being removed?
- is the property leasehold?
- are there adjoining owners above, below or beside?
- who needs to receive notice?
- what notice period applies?
- is a surveyor needed?
- should a schedule of condition be prepared?
- does the insurer need to know?
- have tenants been told about disruption?
- are all documents stored safely?
The key takeaway
Party wall notices are easy to miss, but they can be essential before certain works begin.
Landlords planning extensions, loft conversions, chimney removals, boundary works, structural alterations or excavations near neighbouring buildings should check the Party Wall etc. Act 1996 early.
Planning permission and building regulations approval do not replace party wall procedure.
The safest approach is to check before works start, serve the correct notices, allow time for responses, use surveyors where needed and keep the paperwork.
For landlords, party wall compliance is not just about neighbour relations. It is about protecting the project, the property and the investment.
