Class MA prior approval: offices and shops to homes.

Whether the site has a safe access, the effect of residents’ cars on parking nearby, and how cycles and refuse will be stored. The comparison with the existing commercial use is central.

• A comparison of residential and existing commercial trips.
• Parking demand from census car ownership for similar homes.
• A parking stress survey where on-street capacity is in question.
• Cycle and refuse storage drawn to scale.

Prior approval can only consider the listed matters, so the transport note should answer those questions and no more. A focused note is easier for the council to accept within the determination period.

• A transport note focused on the prior approval matters.
• A comparison of trips between the existing commercial use and the homes.
• Car ownership evidence and, where needed, a parking stress survey.
• Cycle and refuse storage drawn to scale.
• Confirmation that the site access is safe.

A typical case is a two-storey office building converted to 12 flats under Class MA. The council’s question is whether residents’ cars will add to pressure on the surrounding streets. The office car park has eight spaces, which are kept for residents. We show office trips were higher than the residential trips will be, use census data to estimate car ownership, and include an overnight parking survey showing spare capacity nearby.

Prior approval applications are normally decided within 56 days, so the evidence must be ready at submission. The transport matter is about impacts on the highway, particularly safe access to the site, and the council cannot use the process to apply its full parking policy. The note should therefore be focused, factual and proportionate. Where a building is in a controlled parking zone, a permit-free arrangement may be part of the answer.

Where the council raises transport concerns on a Class MA application, they usually relate to parking pressure or the safety of the access. Because prior approval is limited to the listed matters, the response should stay focused on those.

A second application with better evidence is often quicker than an appeal, but both are possible. We can advise on which route suits the site.

We prepare a concise transport note for the prior approval application, and support appeals where transport is a reason for refusal.

The same questions arise in Scotland and Wales, where they are assessed against NPF4 and Scottish guidance or Planning Policy Wales and TAN 18 rather than the NPPF.
