Amenity conditions that cannot be enforced, and why

A condition requiring that a development causes "no undue disturbance to neighbouring occupiers" is worthless. Nobody can say when it has been breached, so nobody can serve a breach of condition notice on it, and the council has bought itself a paragraph of comfort instead of a control. Unenforceable amenity conditions are the commonest drafting failure in delegated decision notices, and they fail on the same two of the six tests every time: precision and enforceability.

The six tests, applied to amenity

The Planning Practice Guidance sets out six tests for every condition. It must be necessary, relevant to planning, relevant to the development to be permitted, enforceable, precise, and reasonable in all other respects. All six have to be satisfied, and a condition that fails one is unlawful rather than merely poor.

Amenity conditions fail more often than any other category because amenity itself is a judgement. Noise, odour, light spill, overlooking and disturbance are experienced subjectively, and the drafting has to convert a subjective effect into an objective requirement someone can measure.

Where that conversion is not made, the condition either restates the policy or restates the officer's hope. Neither is enforceable.

Conditions that require a subjective judgement

Start with the wording that recurs across decision notices: no nuisance, no undue disturbance, no detriment to amenity, no adverse impact on the living conditions of neighbouring occupiers.

Each of these asks an enforcement officer to prove a value judgement to the criminal standard in a magistrates' court, because a breach of condition notice under section 187A of the Town and Country Planning Act 1990 leads to prosecution rather than to an appeal. No prosecutor will run that case.

The fix is to name the effect and the measurement. Instead of no undue disturbance from plant, a rating level not exceeding the background at a stated position, measured over a stated period, by a stated method. Instead of no light spill, vertical illuminance limits at identified windows. Instead of no overlooking, obscure glazing to a specified level with restricted opening, which is why obscure glazing conditions are one of the few amenity controls that consistently survive.

Noise limits without a measurement position

A condition stating that noise from plant shall not exceed 45 dB is unenforceable as drafted, and it appears on decision notices constantly.

Four things are missing. The metric, because 45 dB could be an LAeq, an LA90, an LAmax or an unweighted level. The averaging period, because an LAeq over one minute and over sixteen hours are different requirements. The position, because a level at the plant is unrelated to a level at a bedroom window, and facade measurements differ from free-field by around 3 dB. And the operating condition being assessed.

Ask for all four before the decision is issued. A well-drafted plant noise condition reads more like a specification than a prohibition, and it protects the applicant as much as the neighbour, because a measurable limit that has been met cannot be reopened.

The same discipline applies to conditions attached after a Noise Impact Assessment has been submitted. Where the assessment already defines a position and a criterion, the condition should adopt them rather than inventing a new number.

Hours conditions that fight the use

Hours restrictions are enforceable, which is why officers reach for them. The problem is a different one: the hours often conflict with the use the permission grants.

A restaurant permitted to open until 11pm but conditioned to cease deliveries and waste collection after 6pm has been given an operating pattern nobody can run. A gym with a condition closing at 9pm on a site the applicant justified with early morning and late evening membership data has effectively been refused.

Three checks catch most of these. Compare the conditioned hours with the hours in the submitted application, with any premises licence, and with the pattern the supporting evidence relied on. Where they differ, say so in writing before the decision, because an inconsistency spotted afterwards costs a section 73 application.

Watch also for conditions that regulate matters already controlled by another regime. The guidance discourages conditions duplicating other legislation, and a condition restating the Environmental Protection Act 1990 adds nothing while giving the impression that planning has dealt with the point.

Conditions that control people rather than development

Planning controls the use of land. It does not control the behaviour of individuals, and conditions that try to do so fail on relevance as well as enforceability.

Examples turn up regularly: occupiers shall not park on surrounding streets, residents shall not keep more than one vehicle, no more than a stated number of people shall gather outside the premises, staff shall use public transport. None of these binds anyone the council can identify and prosecute.

Where the underlying concern is real, there is usually a lawful route to it. Car-free development is secured by a planning obligation removing the occupiers' entitlement to residents' parking permits, not by a condition. Management of a smoking area outside a pub is secured by a management plan approved under condition, with the plan itself capable of being checked. Tree protection is secured by requiring works in accordance with an approved scheme, which is why the arboricultural method statement is the enforceable document rather than a general instruction to protect trees.

The distinction matters most on amenity issues arising from a rear extension and its effect on a terraced neighbour, where officers sometimes try to condition behaviour because the design point has already been conceded.

Getting the wording fixed, before and after

Before the decision is the free moment. Officers are usually willing to adjust drafting, particularly where you supply replacement wording that is tighter than theirs, and no fee is involved.

Afterwards there are three routes and each has a cost.

1. A section 73 application to vary or remove the condition, with a fee and a fresh eight weeks, producing a new permission whose own conditions must be checked.
2. A section 96A non-material amendment, which suits corrections that do not change the substance.
3. An appeal against the condition under section 78, within six months of the decision.

Take the third with care. On an appeal the inspector may deal with the application as if it had been made in the first instance, so the permission as a whole is in play rather than just the condition you dislike. Where the rest of the permission is acceptable, that is a real risk and it argues for the section 73 route.

Where a condition is unlawful rather than merely awkward, it can be challenged by judicial review, and in some circumstances an unlawful condition can be severed while the permission stands. That is specialist territory and the six week limit runs from the decision, so take advice early. Supporting the argument with a proper Daylight and Sunlight Assessment or equivalent evidence is what turns a complaint about wording into a case.
