Cllr Gordon Wallace says locals have been in touch with him about the bakers moving into the Chest, Heart and Stroke unit on Fenwick Road in Giffnock.
The politician, who represents Giffnock and Thornliebank, said the concern about the high street favourite opening its first store in the town is not about business in general.
He explained: “It’s about the growing concentration of fast food outlets in this short parade and the impact on parking, litter, noise, and the overall balance of our high street.”
An application to display advertisements at the premises was submitted by Greggs PLC last month as was an application for full planning permission to install replacement air conditioning units.
Documents accompanying the latter show plans for the new shopfront and the interior fit-out to transform the unit.
The application for planning permission has attracted eight objection comments, including from Cllr Wallace.
“At this stage, no change-of-use application has been submitted, so there is no formal route to object to Greggs operating from the unit itself,” said the local politician.
“I am questioning whether this interpretation of national planning rules is correct and have written to senior planning officers for clarification.
“In the meantime, I have formally objected to the air conditioning application on noise and residential impact grounds, (and) raised concerns over the illuminated signage, suggesting limits on brightness and operating hours.
“This is about keeping our high street vibrant but balanced, ensuring residents’ needs are respected alongside business interests.”
In his objection, Cllr Wallace stated that “Greggs would become the fifth food operator in this short terrace offering hot or ready-to-eat food.
“Taken together, this concentration is placing increasing pressure on the surrounding residential environment, particularly on nearby streets such as Park Road,” he added.
“While the unit may appear small, its introduction as a hot food operator with air conditioning and other plant adds to the operational intensity of this location.
“I believe the proposal should be refused or, at minimum, conditioned with strict noise limits and time restrictions, taking into account the cumulative impact on residents.”
An objection submitted by a local resident also raised concerns about an increase in vermin.
“Our area is already experiencing a serious and persistent problem with rats and vermin, a situation largely attributed to the high number of food establishments along the main road,” they said.
“The introduction of another food-based premises, particularly one involving baked goods and takeaway items, is likely to exacerbate this issue.”
The resident also highlighted concerns about traffic and parking arguing that the location offers “little to no dedicated customer parking, and the surrounding streets are already under pressure from limited on-street parking options.”
“We are extremely concerned that this will lead to increased instances of illegal parking,” they said.
Concerns were also raised in the objections about issues such as crowding and litter from school pupils, the negative impact on local character and appearance and the threat to independent local businesses.
Greggs and East Renfrewshire Council have been contacted for comment.
