HMO Conversions St Albans

HMO conversion in St Albans means turning a family house into a shared house, or bringing an existing HMO up to licence standard. The district runs only mandatory HMO licensing, with no additional or selective scheme, and the licence applies once 5 or more people in two or more households share. Its own amenity and fire standards then set the kitchens, bathrooms, room heights and fire doors. We build to those standards and the layout your agent agrees with the council, so the house is ready for its licence inspection.

For St Albans, 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 St Albans: 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 St Albans shared house: C4 and large HMOs

A smaller shared house of 3 to 6 unrelated people is a C4 use, and moving from a family house (C3) to C4 is permitted development unless an Article 4 direction removes that right. The Article 4 directions the district lists for places such as Verulam and Fishpool Street deal with heritage and employment, so ask the planning team whether any direction affects the C3 to C4 change on your street before you buy. Put the answer in writing.

Above 6 residents the house is a large HMO, which is sui generis and needs planning permission, as the St Albans amenity standards note. The 1994 policy on Houses in Multiple Occupation (Policy 7) was deleted without replacement when the new Local Plan was adopted, so a large HMO application is weighed against the 2026 plan as a whole. Get that consent before the building work is priced, because the approved layout may differ from the first sketch.

Housing in St Albans

About 29,270 homes are listed for St Albans, and the mix is 69% houses to 32% flats, with 63% built after 1945, 17% in 1919 to 1939 and 19% earlier.

St Albans HMO licensing: who applies, what it costs in time

Where the building will be a shared house, the St Albans regime is the national minimum. A licence is needed once 5 or more people in two or more households live there, and no extra local scheme sits on top of it. A flat in a purpose-built block of three or more flats is outside mandatory licensing. The landlord or their agent applies. A licence runs for up to 5 years, and varying one later is a separate application, so it pays to build the final layout the first time rather than adding a bedroom after licensing.

Each licensed property gets an inspection covering disrepair, fire safety and amenity concerns, so the build should meet the local standard on day one. We hand the landlord the certificates the application needs: the electrical installation report from a registered electrician, the gas safety record from a registered gas engineer, and the fire alarm and emergency lighting commissioning records. Where the letting needs an EPC, St Albans tells landlords the rating must be E or above.

Room sizes, kitchens and bathrooms in a St Albans HMO

The local standards drive the floor plan. Allow one complete kitchen for each group of five residents, and one more bathroom, with basin and bath or shower, for every further five. No room under 4.64 square metres may be used for sleeping in a St Albans HMO, and since 1 October 2018 national licence conditions have set 6.51 square metres for one adult and 10.22 for two. Every room, bathrooms included, needs headroom of 2.13m or more. Draw the plan to these numbers first, then place the walls.

Attic rooms under a pitched roof are where layouts most often fail, because the usable floor shrinks once headroom is counted. A second kitchen means a second extract route, a new drainage run and more fire separation, so it is designed early rather than squeezed in. En suites take space from bedrooms, so each one is checked against the room size limits before the plumber is booked. Sound insulation between bedrooms is worth building in at the same stage.

Fire doors, alarms and escape in a St Albans HMO

Escape routes in a St Albans shared house are designed to the Fire Safety Guide the council uses, produced in partnership with Hertfordshire Fire and Rescue Service. In practice that means fire doors rated to 30 minutes and one emergency lighting unit on each level. LACORS housing fire safety guidance is the recognised national reference alongside it. A change from a family house to a small shared house is not a material change of use under the Building Regulations. The building work done for it must still comply with Part B, so the protected escape route is built in, not added later.

A fire door only performs as a complete set: the rated leaf, a matching frame, intumescent seals, a self closer and the right hinges. We fit each one that way and label it. Interlinked smoke and heat detection goes in at first fix, with the kitchen on heat detection rather than smoke. Gaps where pipes and cables pass through walls and ceilings are fire stopped, and the stair enclosure is checked before decoration hides it.

• Emergency lighting on the escape route where the house needs it
• Hard-wearing floors, finishes and decoration for a let house
• Self-closing fire doors and frames to every bedroom and the kitchen
