This page explains the process you'll need to follow to complete your home improvement project in the City of Cerritos. For more information, call the Building & Safety Division at (562) 916-1209.

Why the City Has Codes

City approval and a building permit are required for many important reasons:

  • To help ensure that home improvements are attractive and fit well within their neighborhoods;
  • To maintain property values and our quality of life;
  • To help homeowners get their projects done safely and correctly the first time, saving time and money, and most importantly;
  • To protect the safety of your family and your neighbors.

The City uses the current Los Angeles County building code which includes code requirements for electrical, mechanical and plumbing work.

Hiring a Contractor

For many projects, such as building a room addition or replacing a roof, you may want a professional to do the job. A free booklet called "What You Should Know Before You Hire a Contractor," offers hundreds of important tips for residents planning to hire a professional, and is available on the Contractors' State License Board website. Here are a few tips:

  • Shop around. Ask for references and check that the contractor's license and insurance are in good standing.
  • It is advised that the homeowner have the contractor obtain the permit for the project.
  • Know the rules. Make sure the contractor is following City policies and procedures. Make sure he or she has a building permit before starting any work.
  • Check before you pay. Before you pay the bill, confirm that the City has done a final inspection and that the contractor has paid all labor and material suppliers.
