If your lease requires the landlord’s written permission to sublet, get the landlord’s written permission and have at it.
The bridge you don’t want to burn is a bridge to nowhere. You were never going to get a good reference from your landlord, Captain Ahab, anyway.
If you are the only signatory to the lease, one could argue that you should be the one signing the rent checks. If both you and your wife are named on the lease then your landlord is just being an idiot.
Because you live in a single-family dwelling, you are only protected by the “just cause” provisions of the Rent Ordinance, not the price controls. The landlord can increase the rent as much he wants to.
It’s not enough that we in the tenant defense business have to deal with unscrupulous and/or uninformed landlords, we have to deal with tenants who decide they own their units and rent them out like landlords.
As you scramble to get out of the lease and your greedy landlord tries to increase the rent you forgot about the person who will be hurt under this scenario–your subtenant.
