# How to Legalize an Illegal Secondary Suite in Coquitlam or Port Coquitlam
If you own a home in the Lower Mainland with an unauthorized basement suite, you might be wondering how to make it legal. Whether you live in Coquitlam, Port Coquitlam, Burnaby, or Surrey, legalizing your secondary suite is a smart move that can increase your property value and ensure the safety of your tenants.
Why Legalize Your Secondary Suite?
An illegal suite can lead to fines, insurance issues, and complications when selling your home. By legalizing your suite, you ensure it meets the BC Building Code and local municipal bylaws. This protects your investment and provides peace of mind.
Steps to Legalize a Suite in Coquitlam and Port Coquitlam
1. Check Zoning and Bylaws
First, verify that your property is zoned for a secondary suite. In Port Coquitlam, suites are permitted in RS-1, RS-2, RS-3, and RS-4 zones. Coquitlam has similar zoning requirements. You can check your local city's property mapping system or contact the planning department.
2. Apply for a Building Permit
You will need a building permit to legalize your suite. This involves submitting detailed floor plans and ensuring your suite meets safety standards, such as proper ceiling height, fire separations, and egress windows.
3. Upgrade Systems
Often, legalizing a suite requires upgrading your home's systems. You may need a plumbing permit, electrical permit, or gas permit. This is where professional contractors come in. Our team at Budget Heating & Plumbing Services can help ensure your [plumbing](/services/plumbing), [electrical](/services/electrical), and [heating](/services/heating) systems meet code requirements.
If you need to upgrade your heating system, consider installing a high-efficiency heat pump from approved brands like Panasonic or Tosot. We also install Viessmann boilers. Rebates are not guaranteed and homeowners must prequalify prior to installation.
4. Pass Inspections
Once the work is complete, you must pass municipal inspections. This includes building, electrical, and plumbing inspections. After passing, your suite will be officially recognized as legal.
