What Davis's homes mean for your water heater repair and replacement
With a median build year of 1983, Davis's homes sit in the middle of the Sacramento region's age range, and 21% were built in 2000 or later. If your water heater is in the garage, code requires gas burners at least 18 inches off the floor unless the unit is listed as flammable-vapor ignition resistant. When the tank is replaced, expect the water heater plumber to add or update the expansion tank, straps and relief-valve drain so the job passes inspection with City of Davis Community Development and Sustainability Department.
About Davis
Davis runs a Resale Program: residential properties must go through either a city resale inspection or self-certification before a sale, with 1-, 2- and 3-unit properties subject to the inspection process, to confirm minimum building, health and fire-safety standards.

Local rules, utilities and conditions in Davis
PG&E supplies natural gas in Davis. If you smell gas near your water heater, leave the house and call 911, then PG&E at 1-800-743-5000, and keep mops, brooms and laundry away from the heater, as PG&E advises. If PG&E is also your electric utility, it estimates a heat pump water heater costs $1,200 to $5,500 and saves about $118 a year when it replaces a gas unit. The statewide incentives many PG&E customers used are closed: TECH Clean California's single-family incentives were fully reserved in November 2025, and Golden State Rebates' retail offers have ended.
Your water comes from City of Davis Public Works - Water Division, and its annual Consumer Confidence Report lists the water's hardness. Sacramento-area 2025 reports range from soft lake water, about 13 to 27 mg/L for El Dorado Irrigation District, Folsom and Roseville's Folsom Lake supply, to well water above 200 mg/L in some systems. Harder water means more sediment in a tank and more scale in a tankless unit, so ask the water heater plumber how often to flush yours.
Plan on a building permit from City of Davis Community Development and Sustainability Department for a water heater replacement in Davis; HomeGuide notes most cities require one. The permit brings an inspection of the straps, relief-valve drain, venting, gas connection and expansion tank. It also settles who can do the work: the Contractors State License Board says any job that needs a permit requires a licensed contractor, even if it costs less than $1,000. Ask the plumber to pull the permit and show the fee on the estimate.
Davis is on the valley floor, where summers are hot. That matters if you are considering a heat pump water heater: ENERGY STAR says these units should be installed in spaces that stay between 40°F and 90°F year-round, with about 1,000 cubic feet of air around them, and they cool the space they sit in. Ask the water heater plumber whether your garage or utility room fits, and where the condensate line will drain.
Flood notes for Davis
The City says FEMA's current flood hazard areas south of I-80 stop at the west levee of the Yolo Bypass; FEMA's flood layer maps roughly 8% of the city as Special Flood Hazard Area.
Renting in Davis?
Only 44% of Davis homes are owner-occupied, so many residents rent. In California a broken water heater is generally the landlord's to fix: Civil Code section 1941.1 treats a rental as untenantable if it lacks a water supply capable of producing hot and cold running water, and Health and Safety Code section 19211 bars evicting a tenant on the grounds that eviction is needed to strap the water heater. Report the problem to your landlord in writing. State law also requires owners to install carbon monoxide alarms in units with gas appliances.
