The Party Wall etc. Act 1996: Complete Legal Guide

The Party Wall etc. Act 1996 is the legislation that governs building work affecting shared walls, boundaries, and nearby excavations throughout England and Wales. Understanding this Act is essential for anyone planning building works or dealing with a neighbour's construction project. This comprehensive guide breaks down the Act into plain English, explaining your rights and obligations under the law.

What is the Party Wall etc. Act 1996?

The Act was passed in 1996 and came into force on 1 July 1997, replacing the London Building Acts for party wall matters. Its purpose is to:

• Enable building owners to carry out necessary works to party walls and boundaries
• Protect adjoining owners from damage and unreasonable interference
• Provide a framework for resolving disputes without going to court
• Balance rights between neighbours fairly
• Establish clear procedures for notification and agreement

The Three Main Sections:

The Act has three operational sections covering different types of work:

1. Section 1: New building on or at the boundary line
2. Section 2: Works to existing party structures
3. Section 6: Excavations near neighbouring buildings

Section 1: New Building on the Line of Junction

Your Two Options Under Section 1:

Option A: Build Entirely on Your Land (No Consent Needed)

• Build the wall wholly on your side of the boundary
• Must serve 1-month notice on neighbour
• Neighbour CANNOT refuse (you have the right)
• You own 100% of the wall
• You pay 100% of costs
• Neighbour has no rights to use it without permission

Option B: Build Astride the Boundary (Consent Required)

• Build the wall straddling the boundary line (half on each side)
• Must serve 1-month notice
• Requires neighbour's express written consent
• If they consent: Wall becomes party fence wall (shared ownership)
• Costs usually shared 50/50 (unless agreed otherwise)
• Both parties have rights to use it

Section 2: Existing Party Structures

Section 2(2): Specific Works Permitted

Under Section 2(2), building owners have the right to:

1. Underpin, thicken, or raise a party structure or party fence wall
2. Demolish and rebuild a party structure or party fence wall
3. Cut into a party structure for:
   • Supporting beams, joists, rafters
   • Inserting steel beams
   • Installing damp-proof courses
4. Cut away projections or chimney breasts from party walls
5. Expose party structures for necessary works
6. Protect party walls from weather by inserting flashings or weatherproofing
7. Make good, repair, or demolish defective parts of party structures

Section 2(3): Building Owner's Obligations

When carrying out works under Section 2, you MUST:

• Make good all damage caused to the adjoining property
• Repair or rebuild any defects you expose during works
• Carry out works in a workmanlike manner
• Compensate the adjoining owner for any loss or damage

Section 6: Adjacent Excavation and Construction

The 3-Metre Rule:

If you're excavating within 3 metres of your neighbour's building AND your excavation will go deeper than the bottom of their foundations, you must serve a Section 6 notice.

Example: Your neighbour's foundations are 1 metre deep. You're digging 2.5 metres from their building. If your excavation goes deeper than 1 metre, Section 6 applies.

The 6-Metre Rule:

If you're excavating within 6 metres of your neighbour's building, draw a line at 45° from the bottom of your proposed excavation. If that line meets or cuts through your neighbour's foundation, Section 6 applies.

Common Trigger: Basement excavations almost always trigger Section 6 for terraced and semi-detached properties.

Section 6 Obligations:

• Serve 1 month's notice before excavation starts
• Provide drawings showing excavation depth and extent
• Include plans for safeguarding adjoining buildings
• Undertake proper underpinning or support measures
• Monitor for movement or settlement

Section 10: Rights, Costs, and Expenses

Section 10 is crucial – it determines who pays what:

Section 10(4): Building Owner Pays

The building owner (person doing the works) must pay:

• All surveyor fees (theirs, neighbour's, and Agreed Surveyor)
• All reasonable expenses properly incurred
• Schedule of condition costs
• Third surveyor fees (if dispute arises)
• Compensation for damage

What Are "Reasonable" Fees?

Fees must be:

• Proportionate to the works and property value
• In line with local market rates
• Justified by the work actually done
• Not excessive or padding

If fees are disputed: A third surveyor can determine what's reasonable.

Sections 7-9: Rights of Entry and Protection

Section 7(2): Right to Compensation

If your property is damaged by party wall works, you have an absolute right to compensation. The building owner is strictly liable – you don't need to prove negligence.

Section 8: Rights of Entry

Building owners and their surveyors have rights to enter adjoining properties to:

• Carry out permitted works (with 14 days' notice)
• Execute necessary work (immediate if emergency)
• Inspect and measure (with notice)

Obstruction: Refusing reasonable entry can be a criminal offence (fine up to £200).

Section 9: Penalties

• Failing to serve notice: £200 fine + damages
• Refusing entry: £200 fine
• Causing unnecessary inconvenience: £200 fine + damages

The Award Process (Section 10)

When a neighbour dissents or doesn't respond to your notice, the award process begins:

1. Dispute Deemed to Have Arisen (automatic after 14 days or upon dissent)
2. Surveyors Appointed: Each party appoints a surveyor OR both agree on one
3. Award Prepared: Surveyor(s) determine what work can be done and how
4. Award Served: All parties receive copy (14-day appeal period)
5. Award Final: If no appeal, award is binding
6. Third Surveyor Option: If surveyors can't agree, third surveyor decides
