HMO Plans & Planning Applications

Plans, layout drawings and planning application support for converting houses, flats and buildings into HMOs.

An HMO project can be a strong investment, but the planning position needs to be checked carefully before money is spent on purchase, conversion works, licensing, furniture or tenant marketing.

​

In planning terms, a normal house is usually treated as Use Class C3, while a small HMO for 3 to 6 unrelated people is usually treated as Use Class C4. Larger HMOs with more than 6 unrelated occupiers are normally treated differently and may fall outside Class C4 as sui generis use.

​

HMO planning issues can arise where:

​

• A family house is being converted into a small HMO

• A small HMO is being increased to a larger HMO

• The property is in an Article 4 area

• The council has removed permitted development rights for HMOs

• The number of bedrooms or occupiers is increasing

• The layout creates concerns about amenity space

• Refuse, cycle storage or parking needs to be shown

• The property is in a conservation area

• External alterations are proposed

• The council needs clear plans before it can assess the use

• The HMO is already operating and a retrospective application is needed

​

Article 4 Directions are especially important. Where an Article 4 Direction applies, permitted development rights for conversion to an HMO may be removed, meaning a planning application can be required even for a smaller HMO.

​

Ask PAS About HMO Plans, Layouts and Drawings

The plans and drawings are central to an HMO application. The council needs to understand how the property works now, how it will operate as an HMO and whether the proposed layout is suitable.

​

Planning Application Services (PAS) can prepare HMO plans, layout drawings and planning information to help explain the proposal clearly.

​

PAS can help show:

​

• The existing property layout

• The proposed HMO layout

• Number of bedrooms

• Bedroom positions and approximate sizes

• Shared kitchens and living spaces

• Bathrooms, ensuites and WCs

• Access, stairs and circulation routes

• Refuse and recycling storage

• Cycle storage where needed

• Parking and access information

• External changes where proposed

• Whether the proposal is a small HMO or larger HMO

• Whether a planning application, lawful development certificate or retrospective application may be needed

​

PAS can prepare drawings for:

​

• C3 house to C4 HMO conversions

• Small HMO applications

• Larger HMO applications

• Sui generis HMO applications

• HMO layout changes

• Bedroom and ensuite layouts

• House-to-HMO conversions

• Flat-to-HMO proposals

• Existing HMOs needing updated drawings

• Retrospective HMO planning applications

• HMOs in Article 4 areas

• HMOs in conservation areas

• HMO projects connected to building regulation work

​

​

HMO Planning and HMO Licensing Are Different

Planning permission and HMO licensing are separate matters.

​

Planning looks at whether the use of the property is acceptable in planning terms. Licensing looks at whether the property meets the relevant housing management, safety and occupation standards. Government guidance confirms that large HMOs need a licence from the local council, and councils may have extra HMO rules.

​

PAS mainly helps with the planning, drawings and layout side of the project. Where licensing, fire safety or specialist housing standards are involved, PAS can help identify what information may be needed and prepare clear layout drawings to support the wider process.

​

​

What an HMO Planning Package May Include

The exact information depends on the property, location and council requirements, but a typical HMO planning package may include:

​

• Site location plan

• Block plan

• Existing floor plans

• Proposed floor plans

• Existing elevations where needed

• Proposed elevations where external changes are proposed

• Bedroom layout drawings

• Shared amenity layout

• Kitchen, bathroom and ensuite layouts

• Refuse storage information

• Cycle storage information

• Parking information where relevant

• Photos of the existing property

• Supporting planning statement

• Article 4 information where relevant

• Change of use application support

• Retrospective planning support where needed

​

For more detailed or sensitive HMO projects, the council may also ask for:

​

• Management information

• Occupier number information

• Noise or amenity information

• Fire escape layout information

• Waste collection details

• Transport or parking notes

• Heritage or conservation notes

• Evidence of existing HMO use where relevant

​

​

Why Professional Support Helps

HMO applications can be more complicated than normal domestic applications because the council is looking at both the property layout and the effect of the proposed use.

​

Professional support can help you avoid:

​

• Assuming an HMO is automatically permitted

• Missing Article 4 restrictions

• Applying under the wrong use class

• Submitting unclear bedroom layouts

• Failing to show shared facilities properly

• Ignoring refuse, cycle storage or parking issues

• Confusing planning permission with HMO licensing

• Missing external alterations that also need consent

• Creating weak retrospective applications

• Delays caused by council requests for better plans or supporting information

​

PAS can help prepare a clear drawing and planning package so the council can understand the proposed HMO use from the start.

​

​

Full-Service Support from PAS

PAS can provide support from the first planning review through to application submission and later technical stages.

​

This may include:

​

• Initial HMO planning review

• HMO plans and layout drawings

• Existing and proposed floor plans

• Elevation drawings where needed

• Change of use planning application support

• Lawful development certificate advice where suitable

• Retrospective HMO planning support

• Article 4 planning support

• Supporting planning statement

• Help responding to council queries

• Building Regulations drawings where the project moves forward

• Structural design coordination where required

• Fire escape and layout coordination where needed

• Party wall advice and services where needed

• Practical guidance before conversion works begin

​

An HMO project can produce strong rental value, but the planning route, layout and supporting drawings need to be checked before the project goes too far.
