Your Local Security Contractor for San Marino
San Marino sits about 25 minutes west of our Covina shop, just south of Pasadena. The city is almost entirely residential: single-family homes on generous lots, mature gardens, and wide, quiet streets, with shops and offices along Huntington Drive and Mission Street. That shapes the work. For a San Marino home it usually means a driveway gate that suits the house, a quiet and reliable operator, a video intercom at the street, and cameras that cover a deep lot without cluttering it. AD Security, Inc. is a licensed California contractor (CSLB #974487), privately owned by a native Southern Californian, and every project starts with a free written estimate with no hidden fees.

Local Know-How
Design review. San Marino protects the look of its streets. The city requires a permit for fences, walls, and pilasters, and a gate or wall that faces the street commonly goes before the Design Review Committee, which looks at how it fits the home and the neighborhood. We design gates to suit the architecture of the house, and we'll tell you up front if your project is likely to need review.
Permits. Gate operators and their electrical runs typically require city permits as well. As the licensed contractor, we handle the permit process as part of the job; it's included in the written estimate, never a surprise line item.
Deep lots and long driveways. Many San Marino properties set the house well back from the street behind mature landscaping. That means long cable runs, gates placed where a car can pull fully off the road, and an intercom and camera at the entry so you can see and admit visitors from anywhere. We plan the trenching and wiring to protect established gardens and hardscape.
Businesses, schools, and institutions. Along Huntington Drive and Mission Street we install camera systems, access control, and automatic door operators for shops, offices, and medical suites, and we work with schools and places of worship on entry control. We also serve neighboring Pasadena, South Pasadena, Alhambra, and San Gabriel.
