Our Custom Gas Line Solutions for ADUs

We provide tailored gas line systems that fit the unique needs of your ADU. Our work covers everything from building new gas lines to upgrading existing ones. We also offer different types of piping materials to match your project requirements.

New Construction Installation

When building a new ADU, we design and install gas lines that comply with all local codes and safety standards. Our team plans the layout to ensure efficient gas delivery to appliances like stoves, heaters, and water heaters.


We use precise measurements and high-quality materials to create a reliable, leak-free system. This includes testing the gas pressure and connections before the final approval. Our goal is to provide safe and effective gas flow from the main supply to your new ADU.

Retrofit and Upgrade Services

For existing ADUs, we offer retrofit services to update old or faulty gas lines. This includes replacing outdated piping and improving system capacity. We focus on minimizing disruption while working within the current structure.


Our upgrades often involve adding new gas outlets or connecting additional appliances. We make sure all work meets current code requirements and passes inspection. This service is ideal when expanding your ADU’s gas needs or improving safety.

Flexible Piping and Material Options

We provide several types of piping materials, including black steel, corrugated stainless steel tubing (CSST), and flexible polyethylene (PE) pipes. Each material suits different installation needs and budgets.


Black steel is durable and preferred for long-term use but requires professional handling. CSST offers flexibility for tight spaces and faster installation. PE pipes are mainly used for underground lines because they resist corrosion. We help you choose the best option based on your ADU's layout and local code rules.

Our Gas Line Installation Process

We handle every step of gas line installation with care to ensure safety and efficiency. From the first meeting to final inspections, we follow strict guidelines to meet all codes and keep your ADU’s gas system reliable.

Assessment and Consultation

We begin by visiting your property to assess the site and understand your specific gas needs. This includes checking the layout, existing gas lines, and the location of gas appliances.


During this visit, we talk about your ADU’s energy requirements and discuss options for pipe routing. We also review safety protocols and answer any questions you have about the process.


Our team measures distances carefully to estimate materials and costs. This step sets a clear plan for the project and ensures no surprises during installation.

Permitting and Planning

Next, we prepare the necessary plans and documents for city permits. We submit applications that detail the gas installation work, following Los Angeles building codes closely.


We handle all communications with local authorities to speed up permit approval. Our planning includes mapping out the gas line path, sizing pipes correctly, and choosing proper fittings.


This phase also covers scheduling the work to minimize disruptions. We plan for inspections required by the city at various points in the installation.

Installation and Inspection

Once the permits are approved, we begin trenching and laying the gas pipes. We use high-quality, approved materials that meet safety standards. Pipes are installed underground or inside walls as needed.


We perform pressure tests to check for leaks before connecting appliances. Every connection is sealed and double-checked to ensure no gas escapes.


Finally, city inspectors verify that the installation meets code requirements. We work closely with them, making any needed adjustments quickly. After inspection, your gas line is ready for safe use in your ADU.
