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.

Permits are issued and plan checks must currently be submitted by appointment. Please call or e-mail for more information.

Project Development

An overview of the development process in Signal Hill can be found in our Project Development Guide (PDF). This document contains detailed information regarding the city’s review process. It also provides contacts for outside agencies that may have oversight authority and highlights typical development constraints, such as oil wells and seismic hazards. Please also review the Fire Department Requirements (PDF). Applicants are responsible for submitting plans to the County of Los Angeles Fire Department for plan check approval.

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.
