What Davis's homes mean for your drain and sewer cleaning
The median Davis home was built in 1983, after plastic ABS and PVC sewer pipe entered the plumbing code in the early 1970s (City of Tempe). The Insurance Information Institute points to new plastic pipe as a way to keep tree roots out of a sewer line. Joints can still separate and lines can settle, but in homes this age, grease and wipes are the usual suspects.
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
The City of Davis asks residents with a backup to call Public Works at (530) 757-5686 from 7 a.m. to 3:30 p.m., or the police non-emergency line, (530) 747-5400, after hours. Crews check the main and, if your home has a service lateral cleanout, the lateral too, and fix problems in city-maintained sections at no cost. You're responsible for the upper lateral even if roots come from trees on public property, and the city has no laterals in backyards. If no cleanout exists, Davis installs one free after your plumber clears the line.
Repairing or replacing a sewer lateral is construction work that needs a permit from City of Davis Community Development and Sustainability Department. Sewer repair and replacement are routine permits in this region: the City of Sacramento treats them as minor permits, and Sacramento County issues residential sewer line repair permits online. Digging in a sidewalk or street usually needs an encroachment permit too. Make sure whoever pulls the permit holds an active CSLB license; plumbing contractors carry the C-36 classification.
City of Davis Public Works - Water Division supplies water in Davis, and in some cities the same department also runs the sewer. During a backup, every gallon you use has to go somewhere, so stop running water until the line is clear; the City of Lincoln asks residents to stop all water use when a sewer overflows (City of Lincoln). Your water service line is often private too: Placerville, for example, says anything between the meter and the house is the homeowner's responsibility.
Davis is on the flat valley floor, where sewer pipes are laid at gentle slopes. Flat runs leave little room for error: if a section settles, it forms a sag, or "belly," that holds water and debris (Pinellas County). Big shade trees are the other factor here. Roots seek the moisture in sewer lines and work into cracks and joints, so a camera inspection is worth it when clogs repeat.
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?
About 44% of Davis homes are owner-occupied, so many residents rent. Under California Civil Code 1941.1, landlords must keep plumbing in good working order, so a backed-up main line is generally the landlord's to fix. Tenants, in turn, must use plumbing properly under Civil Code 1941.2, and if a tenant's misuse, like grease or wipes, substantially caused the problem, the landlord may not be obligated to repair it (California Department of Real Estate). Report problems to your landlord in writing, and check your lease before hiring a plumber yourself.
