Permits are issued only to plumbing contractors holding state credentials, or to a homeowner installing plumbing at their own home, and no permit is needed for repairs to the working parts of a faucet or valve, or for clearing stoppages.

What Michigan conditions mean for plumbing
Winters here are genuinely hard: deep frost and multi-day freezes make burst protection, heat tape, and drained outdoor lines part of normal Michigan homeownership. Detroit's GLWA-supplied water measured around 107 mg/L (6.3 gpg) in the city's 2025 Water Quality Report: moderately hard, enough to build scale in water heaters gradually rather than aggressively.
| Utility area | Hardness | Class | Source |
|---|---|---|---|
| Detroit | 107 mg/L (≈6.3 gpg) | moderately hard | utility report, 96-142 ppm range, 2025 average 107, 2025 |
