Under COMAR 09.08.01.08 you must obtain all necessary permits and licenses before work begins, and structural and plumbing changes always need them.",{"slug":34,"title":35,"topic":24,"takeaway":36},"dave-wants-no-permit","Can you skip permits if the homeowner asks you to?","No. COMAR 09.08.01.08 makes pulling permits your duty as prime contractor, whatever the homeowner wants. Skipping them risks license revocation, lawsuits, and criminal liability if something fails.",{"slug":38,"title":39,"topic":24,"takeaway":40},"dave-comes-around","How do you build permit costs into a contract?","Include permit costs in the estimate and the contract so the price is transparent.

Cosmetic work and like-for-like fixture swaps usually need none, taller fences often do, and water heaters usually do because of gas, water, and venting. When in doubt, pull the permit.",{"slug":46,"title":47,"topic":24,"takeaway":48},"property-manager-volume","Do cosmetic bathroom refreshes in rentals need permits?","It depends on the actual work.

Your $50,000 liability insurance responds to the claim, but because the work was never permitted or inspected, you also answer to the MHIC, and the homeowner's request is no defense.",{"slug":58,"title":59,"topic":24,"takeaway":60},"inspection-day","How should you handle a problem the inspector finds?","Acknowledge the discrepancy and commit to correcting it before re-inspection.
