What is Sui Generis Planning in HMOs? What You Need to Know
Sui Generis Meaning in HMO Planning Sui Generis is a type of planning application used for properties that do not fall into any specific category. The latin term “sui generis” means “in a class of its own”. There are several buildings that fit into the Sui Generis planning category, including buildings such as theatres, nightclubs and casinos. It is also used to class HMOs that fit certain criteria. As far as HMO planning classes are concerned, there are generally 3 to be aware of. To summarise, this means that up to 6 occupants, an HMO will fit into the C4 use class. Anything higher than this (7+ occupants), and Sui Generis planning is required. Use Class Occupancy Tenant Type Property Type C3 Up to 6 occupants Single household Residential C4 3 – 6 occupants Separate households HMO Sui Generis 7+ occupants Separate households Large HMO How Does C4 Planning Differ From Sui Generis Planning? The planning process for Sui Generis properties tends to be more complex and involves some additional considerations compared to C3 to C4 or C4 to Sui Generis. The first consideration is that often C3 to C4 can fall under what is known as permitted development. This planning right allows you to change the use class of the property without requiring a full application to your local planning authority. However, you may still need to take into account other considerations, such as Article 4 directions. Sui Generis, however, will always require a full planning application, regardless of whether you are changing the property from C3, C4 or even from another Sui Generis building (e.g. if you are converting a nightclub into an HMO). Because a Sui Generis property is considered to be the closest to commercial use, the requirements are stricter and consider the wider implications of the HMO on the local area. For example, a comprehensive assessment of factors such as the potential impact on the local area, noise pollution, traffic impact, and other considerations related to the particular use.

Why Do Councils Require Sui Generis Planning Applications? Local planning authorities are concerned about how proposed HMOs could potentially impact the local policies in force in your area. As you might assume, councils want to prevent a huge influx of large HMOs in their district, which if not controlled could put a big strain on local services as well as cause overcrowding or an increase in anti-social beheviour. Large HMOs occupy a greater number of tenants and, therefore, councils require the opportunity to first assess the wider impact of proposed HMOs on the local area before they are granted permission. Some core elements that local councils will consider include: What Does a Sui Generis Planning Application Entail? If you are looking to invest in a large HMO over over 6 occupants, you will need to know what is required from a Sui Generis planning application (as well as how to make yours a successful one). Design & Access Statement The first core component of your Sui Generis planning applications is your Design & Access Statement. This is essentially a small report that needs to accompany your application and it details the process involved in the development proposal and explains the your designs. The DAS essentially will explain the design concepts and principles that have been applied to your HMO development. The main reason for requiring this is so that your local planning authority understands that you have considered your HMO’s immediate and wider impact in terms of physical, social and economic factors. Your DAS will include elements such as: A well prepared DAS is a crucial part of ensuring your planning officer sees you have fully considered your resposbilities to access and local policies, and that this is reflected in your proposal. Drawings Another core part of your Sui Generis planning application is detailed drawings. You will require drawings for both Existing and Concept. Existing Your existing drawings should illustrate how your chosen property currently looks before any development work has taken place. These drawings should include plans, sections and elevations and need to contain the correct level of detail required for the application. Generally, most property owners should already have existing drawings of the property. However, if you do not, this is something that you will need to obtain, which you can do through a measured survey. If you are working with an HMO architect or project manager, they can generally help you take care of these drawings and will understand the exact format that local councils will require. Concept The concept drawings you provide in your application will demonstrate the proposed changes to the property following the development and how you plan for the space to look afterwards. There are several factors that will play a part in your proposed development and concept drawings, including: An OS Map (Ordinance Survey Map) is also required as part of your Sui Generis application to show the location of the property in the neighbourhood. Existing and Concept drawings do require skill, experience and precision to ensure the correctly convey everything that is required for a planning officer to consider the application. When working with HMO architects or professionals, they will be able to help you with pulling together fully compliant, high quality drawings to ensure a smooth application process. Flood Risk Assessment If your proposed HMO falls into what is considered a “high-risk zone”, you will need a flood risk assessment as part of your Sui Generis application. You can use the Government UK Flood Risk Service to work out the flood risk score for your specific area. If you require a flood risk assessment, this can be conducted by an assessor. Transport Statement Though not a requirement, a common pitfall of many Sui Generis applications is related to the access to transport and parking availability. A solid and
