Warren is the largest city in Macomb County, directly north of Detroit across Eight Mile. Warren's housing is mostly 1950s and 1960s, spread over a big area, so it's one of the busiest places in the metro for routine drain, sewer and water heater work.
How old are Warren houses?
Warren is younger than the inner-ring suburbs. ACS 2020–2024 data put the median year built for its 57,958 housing units at 1965, the third-newest housing stock of the 28 suburbs we cover, with only 32% built before 1960. The 1960s (36%) and 1950s (22%) were the biggest building periods.

| 1950s | 22% | 21% |
| 1960s | 36% | 8% |

What Warren plumbing is usually made of
Newer Warren homes are more likely to have copper supply lines and, from the 1970s on, plastic (ABS or PVC) drain piping, with clay, cast-iron or plastic laterals depending on the subdivision. The common calls shift accordingly: water heaters reaching the end of their life, fixture and kitchen-line clogs, and laterals where tree roots have found older joints.
Owners, landlords and multi-unit buildings in Warren
About 71% of occupied homes in Warren are owner-occupied, and 75% of housing units are single-family detached houses (ACS). Only 4% of units are in two- to four-unit buildings and 11% in larger buildings, so most plumbing calls here come from homeowners responsible for everything from the meter to the city sewer connection.
Local plumbing notes for Warren
Warren is Macomb County's largest city, with about 58,000 housing units and a median year built of 1965. Only about 32% of homes predate 1960, but the 1950s and 1960s neighborhoods are vast, so routine drain, sewer and water heater work is constant. About 71% of homes are owner-occupied. Warren's plumbing permit application asks for the contractor's plumbing license information, and the city keeps a plumbing article in its code of ordinances, so expect a properly permitted job to be documented. Southern Warren, closer to Eight Mile, tends to have older houses than the northern part of the city. If you're in one of Warren's older blocks, check whether your lateral is clay; root intrusion is the most common reason for repeat backups.
Water heaters in Warren
Most Warren homes run on gas (88% heat with utility gas per ACS), and so do most of their water heaters. A tank that's leaking, a pilot that won't stay lit or a relief valve that drips are the usual reasons people call. Replacements are a permitted job in Warren; we handle the permit with the Warren Building Division. More on our water heater page.
Freeze risk for Warren plumbing
The nearest long-term NOAA station, Detroit Metro Airport, averaged 111 nights at or below freezing per winter from 2015-2025, and 30 days that never got above 32°F. In 9 of those 10 winters the low hit 0°F or colder at least once. Newer Warren homes are usually better insulated, but hose bibs left on and lines in garages or over unheated spaces still freeze. See our frozen pipes guide or, for a split pipe, the emergency plumber page.
Water service, sewer laterals and lead lines in Warren
Most suburbs in Wayne, Oakland and Macomb counties buy wholesale water from the Great Lakes Water Authority, with your city handling the local mains, meters and billing. Michigan's Lead and Copper Rule requires every community water supply to replace all lead and galvanized-previously-connected-to-lead service lines by January 1, 2041, at the supply's expense, and to notify affected homes every year. If you've received a letter from Warren about your service line, that's why.
On the sewer side, the pipe from your house to the public sewer is the property owner's responsibility in most Detroit-area cities, so a root-clogged or broken lateral in Warren is usually a private repair. A camera inspection shows exactly what's wrong; see sewer line repair.
Plumbing permits in Warren
Warren's Division of Buildings and Safety Engineering takes plumbing permit applications, which ask for the contractor's plumbing license information. The city also keeps a plumbing article in its code of ordinances. Source: Warren Building Division. Statewide, plumbing is governed by the 2021 Michigan Plumbing Code (effective March 12, 2024), with one- and two-family homes following the plumbing provisions of the Michigan Residential Code. Clearing a stoppage or repairing only the working parts of a faucet generally doesn't need a permit; replacing pipe or a water heater does.
