Complete Guide to Gas Installation and Requirements

Accessory dwelling units (ADUs) need utilities to stay comfortable. One of the most common questions we receive at Valley Home Builders is whether you can have gas in your ADU. The short answer is yes, but there are factors to consider.

Gas Installation Options for ADUs

When planning an ADU gas installation, you typically have two options: connect to your main home’s existing gas line or install a new line dedicated to the ADU. If you opt to share the existing service, a separate gas meter for the ADU may not be necessary, especially if the space does not include vented gas appliances.

However, if the ADU will have its own kitchen or heating system, a new meter might be more practical for usage tracking and billing. It may also be a requirement in your municipality.

In California, gas line installations must be completed by a licensed professional and comply with local and state ADU utility requirements. Every city may have unique rules, but state ordinances generally take precedence.

Gas vs. Electric: Making the Right Choice

Gas appliances often have lower operating costs and continue working during power outages. On the other hand, all-electric ADUs have environmental advantages, require less infrastructure and usually have simpler installation.

Electric appliances, particularly induction cooktops, are closing the gap on performance and efficiency. Plus, there is a growing trend toward all-electric ADUs in the South Bay Area, driven by local building codes and sustainability goals.

Common Gas Appliances for ADUs

Depending on how your ADU will be used, you may want to include several gas-powered features. Popular options include:

• Gas water heaters that heat quickly and efficiently.
• Gas stoves and ranges for precision cooking.
• Gas dryers that often perform faster than their electric counterparts.
• Gas furnaces and wall heaters that save space in smaller ADU spaces.

Any gas appliances will require careful planning for ventilation and square footage.

Installation Process and Costs

Installing a gas line to your ADU involves several steps:

• Initial site inspection
• Planning utility access
• Obtaining permits
• Trenching
• Laying the line
• Connecting appliances
• Scheduling inspections

While every project is unique, you should anticipate a multiweek process depending on complexity and city approvals.

Costs vary based on distance, appliance count and whether a new meter is needed. Valley Home Builders helps you manage every step of the process with transparency. We take care of every detail and can consult with you on determining the right utilities for your ADU, as well as take care of any permits or requirements.
