HMO Conversions Letchworth Garden City

An HMO conversion in Letchworth Garden City turns a family house into a shared house, or brings an existing HMO up to the North Herts licensing standards. North Herts requires an HMO licence for any private property rented to 5 or more unrelated tenants, however many storeys it has, and it sets local standards for kitchens, bedroom sizes and fire precautions. The landlord applies for the licence and any planning permission. We build the rooms, kitchens, bathrooms and fire protection to those standards and supply the floor plan and paperwork the application asks for.

For Letchworth Garden City, a light HMO conversion for four to six tenants typically costs £40,000 to £75,000 in construction, or £90,000 to £150,000 with an en-suite to every bedroom (Mayfair Studio and LetCompliance, 2026); a Hertfordshire price follows a site visit. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Letchworth Garden City: we build the fire doors, detection, bathrooms and kitchens to the council's HMO standards, the landlord applies for the licence, and a registered electrician certifies the electrics.

Planning for a shared house in Letchworth Garden City

Whether a Letchworth Garden City HMO needs planning permission turns on how many people will live in it. A shared house for three to six unrelated people is use class C4, and general law lets a family house change to C4 without an application unless an Article 4 direction removes that right. No such direction applies in Letchworth. North Hertfordshire's two directions made on 9 October 2012 cover the Hitchin and Stockens Green conservation areas, and its 2022 town centre directions remove only the Class MA right.

A house for seven or more sharers is different. It falls outside C4 as a sui generis use, so it always needs planning permission, and the application has to show the rooms, kitchens and parking can cope. Even at C4 size, new partitions, fire doors and a second kitchen can need building regulations approval. Settle the occupancy you are aiming for before your designer draws anything, because it decides the planning route, the licence and the fire standard.

When a shared house needs a North Herts HMO licence

If you let a house in Letchworth Garden City as a shared home to five or more unrelated tenants, you need an HMO licence from North Herts. That applies to any private property rented as a shared house, flat or bedsit, however many storeys it has. North Herts asks for the application at least three months before the HMO starts operating. Count back from the date the first tenant is due, so the application goes in on time and the works it describes are already fixed.

The application has to include proof of planning permission where it is needed, plus any relevant Building Control documents. It also needs a floor plan giving bedroom and shared room sizes in square metres, and the positions of fire alarms, fire doors and emergency lighting. We supply a plan of the layout as it is being built, and the building control paperwork, so the licence application matches the house. That is why the fire alarm and door positions are fixed before first fix, not at handover.

Kitchens and room sizes in a North Herts shared house

The North Herts HMO standards set how much kitchen a shared house in Letchworth Garden City needs. They require a full set of kitchen facilities for every five occupants, sited no more than one floor from the bedroom where practicable. They also call for at least six power outlets above the worktops for every five occupiers sharing a kitchen. In practice that fixes the worktop length and the electrical layout before the kitchen is ordered, and it can push a larger house towards two kitchens on different floors.

Bedroom size is the other constraint on layout. The national licence minimums are 6.51m2 for a single adult and 10.22m2 for two, and no room under 4.64m2 may be slept in. Above that single room minimum, the local standard aims for 8m2. A room at 6.51m2 is only accepted if the Licensing Team decides suitable communal space is available. So a smaller bedroom works only where the house keeps a proper shared living room or kitchen with dining space, and we plan partitions with that in mind rather than squeezing in one more room.

Fire precautions and sound in a Letchworth Garden City HMO

Fire protection is often the largest item in an HMO conversion in Letchworth Garden City, and North Herts applies additional standards on fire precaution facilities and equipment in larger properties. The recognised guide is the LACORS housing fire safety guidance, which sets the alarm system, fire doors and escape route by the number of storeys and occupants. A typical scheme brings interlinked detection in every room, self closing fire doors to bedrooms and the kitchen, and a protected stair down to the front door.

Building control checks the fire work under Part B, and Part A where walls or floors are altered, and the completion paperwork goes with the licence application. Sound between bedrooms matters too, because each room is a separate letting with its own hours. We add insulation and a second layer of board to the partitions and floors that divide rooms. Where the letting needs an EPC, the minimum energy efficiency standard requires at least band E, for existing tenancies as well as new ones since 1 April 2020, so insulation and heating controls are best upgraded while the house is stripped.

• Bedroom layouts checked against the national minimum room sizes
• Thumb-turn bedroom locks that open from inside without a key
• Electrics extended to every bedroom, certified by a registered electrician
