Do I Need a Permit to Install a Smart Lock? in Verenigde Staten
Installing a smart lock on an existing door almost never requires a permit. Replacing a standard deadbolt with a smart deadbolt or adding a smart lock to an existing deadbolt prep is considered a hardware swap, not a building alteration. However, permits may be triggered if the installation requires new electrical wiring (hardwired locks needing a dedicated circuit), if you are modifying a fire-rated door assembly, or if the work involves running low-voltage wiring through walls in jurisdictions that regulate low-voltage installations. Renters should check lease terms and landlord approval requirements.

Country-specific detail
In the US, replacing a deadbolt with a battery-powered smart lock (Schlage, Yale, August, etc.) is a hardware swap that requires no permit in any jurisdiction. The work does not alter the structure, electrical system, or plumbing. However, if a hardwired smart lock requires running new electrical wire to the door frame, an electrical permit may be needed — though most residential smart locks are battery- or PoE-powered. In commercial buildings, installing electromagnetic locks or electric strikes on fire-rated door assemblies may require a permit and must comply with NFPA 80 (fire door assembly standards) and ADA egress requirements. Some states require a low-voltage contractor license for running structured wiring through walls. HOA rules may restrict exterior hardware changes on entry doors.
