San Francisco Homeowners Face New Reality: Converting Gas Water Lines Under the City’s All-Electric Building Ordinance
San Francisco’s groundbreaking All-Electric New Construction Ordinance is reshaping how homeowners think about their plumbing systems. In such buildings, all indoor and outdoor space-conditioning, water heating, cooking, and clothes drying systems must be all-electric. The ordinance prohibits installation of infrastructure, piping systems, or piping for distribution of natural gas or propane to such uses. While this regulation primarily affects new construction, it’s creating a ripple effect that’s impacting existing homes and driving demand for professional plumbing services to handle gas line conversions.
Understanding San Francisco’s All-Electric Mandate
San Francisco Building Code 106A.1.17 requires applications for permits submitted after June 1, 2021 to construct new buildings to be designed and constructed such that all space conditioning, water heating, cooking, and clothes drying systems are all-electric, as defined, and prohibits installation of infrastructure, piping systems, or piping for distribution of natural gas or propane to such uses. San Francisco Building Code Section 106A.1.17 applies to all permit applications submitted on or after June 1, 2021 proposing to construct one or more new buildings in San Francisco.
The city’s motivation is clear: San Francisco has a target of reducing carbon emissions 68% by 2030, and zero net emissions by 2050. In 2018, buildings accounted for 44% of the city’s carbon footprint, and 84% of local emissions from buildings arise from the use of natural gas. Additionally, Natural gas poses risks to the health and safety of San Franciscans, as well as to the climate. All-electric construction eliminates both indoor and outdoor air pollution from burning natural gas, which has been linked to asthma in children, respiratory illness, cardiovascular disease, and premature death.
What This Means for Existing Homeowners
While the ordinance primarily targets new construction, existing homeowners are increasingly choosing to convert their gas systems voluntarily. This ordinance prohibits retrofitting all-electric buildings with gas piping systems. This creates a one-way path toward electrification that many homeowners are embracing proactively.
The conversion process typically involves several key steps that require professional plumbing expertise:
- Safely disconnecting and capping existing gas lines
- Installing electric water heater systems, often heat pump models
- Upgrading electrical systems to handle increased load
- Ensuring proper permitting and code compliance
The Role of Professional Plumbers in Gas Line Conversion
Converting from gas to electric water heating isn’t a DIY project. It requires licensed professionals who understand both gas safety protocols and electrical requirements. You need a permit before cutting into or replacing pipes, particularly pipes that will be covered by a wall or buried in the ground. You must be a licensed contractor registered with the City of San Francisco to apply for a plumbing or mechanical permit online.
When searching for qualified professionals, San Francisco homeowners need a Plumber in San Francisco, CA who has experience with both gas line work and electric system installations. The complexity of these conversions requires expertise in multiple areas of home systems.

The Future of San Francisco Plumbing
San Francisco’s all-electric ordinance represents a significant shift in how the city approaches building systems and energy use. Natural gas line ruptures contributed to half of the fires in San Francisco after the 1989 Loma Prieta earthquake. By moving toward all-electric systems, the city is addressing both environmental and safety concerns.
For homeowners, this transition presents an opportunity to modernize their homes with more efficient, safer systems. Heat pump technology is especially well-suited for San Francisco’s mild climate and reduces exposure to pollution and fire risk, as gas-fired appliances can release harmful pollutants into your home.
