"The government" probably doesn't say it; people who are negatively impacted or forced to take on extra risk because of mining activity are the ones to say something. For example, the electricity provider probably objects precisely when the current you're drawing exceeds the safe limits of their equipment and wiring. If they're particularly on the ball, they at least come investigate as soon as they notice an unusually high current-draw for that individual residence. You're generally free to exceed the safety limits of the equipment and wiring within your own structure, since you pay all the costs of any resulting incident/accident. But if you're covering those costs via a homeowner's insurance policy, that policy/company might have some things to say about current loads and building codes, as prerequisites for covering you. In a rental property your ability to run mining rigs would depend on the lease, and the landlord's degree of vigilance in monitoring unusual electrical loads. If there's an incident or fire due to current-draw nobody noticed, it probably ends up in court. If you promised (by signing a lease with a relevant clause in it) that you wouldn't engage in excessive current-drawing activities, you lose that case pretty much instantly. Otherwise it'll be up to their side to prove that your negligence caused any losses or damages to the landlord's property, not to mention other tenants' property if they also sue you.
