I will post the entirety of my comments to a planning application for a very similar situation - hopefully there is something helpful in it (the application was declined, I believe there were a number of objections)
I live on this road and I would like to object to this application.
It has become noticeable that we already have a number of HMOs, unsupported and supported living accommodation properties in the area. This is starting to have a material effect on the quality of life locally for residents, in an area with reduced capacity for community support.
Lots of houses on this road are already converted to flats and this removes yet another family size accommodation from the area. There is an existing concentration of non-family residential accommodation houses. As such the proposal would be contrary to Policies PG3, TP30 and TP35 of the Birmingham Development Plan 2017, Saved UDP Policy 8.27, Area of Restraint Handsworth, Sandwell and Soho adopted as Supplementary Planning Guidance, and the National Planning Policy Framework.
There is an undersupply and evidenced demand for family housing of the size and nature of the application premises. No planning justification or an identified social need for the proposed HMO has been made. As such the proposal would be contrary to TP30 & TP35 of the Birmingham Development Plan 2017, saved Policies 8.27 of the UDP 2005 and the National Planning Framework.
It has been repeatedly documented that the increase of HMO numbers leads to risk of increased crime, antisocial behaviour, noise impact and littering, as there is no regulation or management of sites. This has been recently covered in a series of investigations in the Birmingham local press which have exposed the inability of the city council to properly regulate this sector of accommodation.
HMO accommodation is often temporary due to its nature and therefore encourages a high turnover of residents. This contributes to decline in the area, as there is no community unity or cohesion.
These documented negative effects and problems associated with HMOS are exacerbated by similar problems from other types of non-family residential accommodation in the area, e.g. 'exempt accommodation'. Hence the numbers of all types of non-family residential accommodation in the area should be taken into account, when deciding whether the addition of another HMO would be appropriate. I believe that the evidence suggests that it is not appropriate for this application to be approved as it would contribute to declining amenity within Handsworth.
