Building Safety


The Building Safety program regulates the building construction process by conducting field inspections, coordinating the plan check process by logging and reviewing plan submittals for compliance with local and state codes, issuing certificates of occupancy, and issuing permits.

Building Safety Month 2022: "Safety for All"

May 2022 is the 42nd annual Building Safety Month, a worldwide campaign presented by the International Code Council, of which the City of Signal Hill is a member. This year’s campaign, “Safety for All: Building Codes in Action,” raises awareness about the importance of building codes in ensuring safety in the spaces in which we live, work and learn. Homes and buildings that are built in compliance with building safety codes are essential to helping communities stay safe, resilient, and energy and water efficient. 

The City currently uses the 2019 California Building Codes and the 2020 Los Angeles County Fire Code.  The Building Division of the City of Signal Hill is here to help residents build and maintain their property safely.  If you have questions regarding building permits for your property improvement project, please contact 562-989-7348.

Standard Urban Stormwater Mitigation Plan (SUSMP)

All new commercial and residential developments need to do their part to help protect the quality of our rivers, wetlands and ocean. To help accomplish this, the State Regional Board requires the preparation of a Standard Urban Stormwater Mitigation Plan (PDF) (SUSMP).

Water Meter Plan Check

To assure the correct sizing of water meters the City requires a water plan for new development projects. Projects must be sized in conformance with the California Plumbing Code. A plan showing the fixture count and estimated domestic, fire and irrigation systems demand may be required.
