Landlord guide
What happens when a cannabis farm is found in a rental property?
A practical walkthrough for landlords, letting agents and property managers in West Yorkshire, from making the property safe through to re-letting it.
1. Make the property safe before anyone works in it
A former grow is not a normal empty house. The electrical system is often bypassed or tampered with, so the supply should not be assumed safe until it has been checked by a qualified electrician. Ventilation and ducting are frequently cut through ceilings, floors and external walls, and there may be standing water, mould, or chemicals left behind. Nobody should enter to clear anything until the power has been made safe and the building has been assessed for damp, mould and structural damage.
2. Record everything before you touch it
Photograph each room, the damage, the equipment left behind, the meter and any police paperwork. If you are claiming on landlord insurance, this record is what the loss adjuster will ask for. Keep the crime or incident reference number the police gave you — most insurers and specialist contractors will ask for it, and it is much harder to obtain later.
3. Understand what clearance actually involves
Clearance is not a house clearance in the usual sense. Specialist work typically covers removal of grow equipment, ducting, lighting rigs and irrigation, safe disposal of chemicals and contaminated waste at licensed facilities, stripping contaminated plasterboard, flooring and insulation where necessary, then deep cleaning and odour treatment. Restoration — replastering, electrics, redecoration and reinstating ventilation — usually follows. Because the waste is classed as contaminated, it cannot go in a standard skip.
4. Check who you are appointing
Ask for a written method statement, evidence of waste carrier registration for contaminated waste, public liability insurance, and confirmation of how the work will be certified. A firm that turns up without paperwork is a risk to your insurance claim. This is the main reason we exist: to put landlords in front of contractors who do this kind of work regularly, rather than a general cleaner learning on your property.
5. Expect a realistic timescale
A straightforward clearance and deep clean on a small terraced property can be measured in days, while a larger house needing plaster stripped, electrics replaced and full redecoration can run to several weeks. Tell your insurer and your tenants or prospective tenants early, and build the delay into your void period rather than promising a re-let date that slips.
6. Get the property ready to let again
Before re-letting, arrange a fresh electrical installation certificate, confirm the ventilation and extraction are working, and ask for written confirmation of the cleaning and any testing carried out. New tenants, and their insurers, increasingly ask whether a property has any history of this kind, and having a documented clearance record is the cleanest answer.
