Thank you for your question.
House soiling is very frustrating. Would you mind answering few questions to obtain further information and confirm if he had a thorough medical check-up?
Did he ever urinate in any of the litter trays since being adopted?
Have you made any changes to the litter type, litter tray or latrine location since adoption?
When or at what age did he start house soiling and do you recall roughly the trigger for the behavior? (i.e. did you move house, carried renovations, went on holidays, got a new pet, think back on any major event)
When he urinates does he squat to urinate or spray (vacates small volumes of urine onto vertical surfaces), please capture on a video if unsure.
Where exactly is he peeing, is it on any particular substrate or item (i.e. tiles, carpet, bed, shirt, furniture), is it always the same substrate or different surfaces?
Do you scoop ALL the litter trays twice daily and clean them regularly?
When it comes to elimination outside the litter, initially it’s imperative to undergo a medical checkup, a behavioral and environmental evaluation to identify potential emotional motivations (fear/anxiety/panic) for the behavior.
There could be number of motivations your cat is peeing everywhere such as a medical problem, aversion to litter type, litter-box including location, marking behaviors, poor house-training, preference for a specific site and substrate, social and environmental stressors.
Cat owners are unaware that it’s instinctive for cats to urinate separately from where they defecate, hence why he doesn’t urinate where he poops. It’s worth conducting a Litter type and/or Litter Tray preference test by offering 3 different options of litter and latrines. Please do not move existing tray in which he defecates since it may confuse him.
Be mindful that peeing outside the tray can become a habit hence early intervention is crucial. Most cases can be treated successfully with supplementation, environmental as well as a behavioral modification plan together with medication for severe cases.
My recommendation would be to consult a Veterinary Behaviorist or request a vet referral to a Feline Behaviorist.

Hope this gives you a little bit of guidance.
