HMO Planning
Converting a property into a House in Multiple Occupation (HMO) requires careful planning and a clear understanding of local council regulations. These properties typically feature separate bedrooms with shared facilities such as bathrooms and kitchens, making compliance with planning permission, permitted development, and architectural requirements essential.

With our extensive experience and strong relationships across London boroughs, we help ensure your HMO project meets all regulatory requirements and progresses smoothly.

The planning decision usually takes 8–10 weeks, depending on the council and project complexity. Accurate planning drawings and professional architectural support from AA Drafting Solutions can help avoid delays and requests for additional information.
USE CLASSES
The Town and Country Planning Order puts uses of land and buildings into various categories known as ‘Use Classes’ including houses. If you intend to use a building or a house for any new purpose you may require a ‘change of use’ permission from the local authority. This also falls under existing use applications in which if the property has been acting under a certain use class for over 4 years AA Drafting Solutions can apply for the property to be permanently assigned to that use class.
