What San Francisco, CA Homeowners Ask About Home Security

Who issues permits for home security projects in San Francisco?
Permit rules depend on the project's scope. Check with the San Francisco County or San Francisco building department before work starts - unpermitted work can complicate insurance claims and future home sales.
How many quotes should I get for home security work in San Francisco?
Three written quotes is the practical minimum in San Francisco. It is enough to spot an outlier - high or low - and to compare how each company defines the scope, which is where most pricing differences hide.
How do I verify a home security contractor's insurance in San Francisco?
Request a certificate of insurance directly and check the dates and coverage limits. Established home security companies serving San Francisco expect this question; hesitation to answer it is a red flag in itself.
How do I avoid a bad home security contractor in San Francisco?
