Right to Light Disputes: How to Avoid and Resolve Them

Right to light is a private property right that can halt development with an injunction or reduce schemes to comply. Established South African case law has made right to light a critical pre-development check for tall or close-set builds.

How rights arise

• Express grant in title
• Prescription (20+ years uninterrupted enjoyment)
• Implied grant by reservation

Most residential property in South Africa has prescription-acquired rights by virtue of age.

Measurement

The test is whether the neighbouring building retains adequate light — measured by the Waldram method or modern alternatives (Agrément South Africa / CSIR Site Layout Planning). Threshold is typically 50% of the room remaining "well-lit" (above 0.2% sky factor).

Remedies

• Injunction — court order to demolish or reduce. Possible but courts often refuse.
• Damages in lieu — financial compensation. More commonly awarded; can be substantial.

Coventry v Lawrence and similar cases have increased awards of damages — including "developer ransom" amounts based on profit share.

Pre-development checks

• Right to light survey (specialist consultancy)
• Calculate impact on adjacent rooms
• Identify properties with arguable rights
• Plan mitigation: redesign, negotiated release, indemnity insurance

Indemnity insurance

Title insurance can cover residual right-to-light risk. Cost varies enormously by scheme; typical 0.2–1% of construction cost. Cheaper than redesign in many cases.

Section 203 Spatial Planning and Land Use Management Act (SPLUMA)

Public authorities can use s203 powers to extinguish private rights including right to light, with compensation payable. Used increasingly for major regeneration schemes. Compensation is at market value, much lower than ransom levels.

The 50% rule of thumb

If the proposed scheme would leave a neighbour's habitable rooms at less than 50% well-lit, expect a claim. Above 50%, claims are possible but harder to make stick.
