Our Gas Line Installation Process

Initial Assessment and Planning

We start by inspecting your property to understand the site conditions. This includes checking the existing gas lines, meter location, and where the new ADU will connect.


We also review your ADU’s gas needs, such as appliances or heating systems. This helps us size the gas line correctly for safe and efficient use.


We then create a detailed plan showing the gas line path, materials, and connection points. Our team ensures this plan fits local Orange County requirements.

Permitting and Code Compliance

We prepare all the necessary documents to get permits from Orange County authorities. This paperwork shows that our design meets safety and building codes.


We keep track of all deadlines and requirements to avoid project delays. Our experience with local codes helps us address any questions inspectors might have.


Once permits are approved, we schedule the installation. We always follow the latest California and Orange County gas codes during the work.

Installation and Final Testing

During installation, we carefully lay pipes and connect them to your main gas supply. We use materials approved for outdoor and underground use to prevent leaks or damage.


After installation, we perform pressure tests to check for leaks. This step is crucial to ensure the system is airtight and safe to operate.


Finally, we notify the gas company to inspect and approve the connection. Only after this inspection do we activate the gas supply to your ADU.
