Phoenix slab leak statistics, 2026

2026 Phoenix Slab Leak Detection Mesa Plumbing Permit Index

The 2026 Phoenix Slab Leak Detection Mesa Plumbing Permit Index found 364 City of Mesa building permits issued in calendar year 2025 with Type of Work exactly “Plumbing,” counted from the current Mesa Open Data dataset last updated 2026-11-09.

Pulled 2026-11-10. This is a count of published public records, not a bid from Phoenix Slab Leak Detection, not a diagnosis, and not a promise that a named firm will arrive.

How the index was counted

The current City of Mesa “Building Permits (Commercial, Residential and Signs)” dataset (Socrata id m2kk-w2hz), last updated 2026-11-09, was queried for rows whose type_of_work field equals “Plumbing,” grouped by issued_year. Calendar year 2025 returned 364 rows. The same query returned 315 rows for 2024 and 372 rows for 2026 through the dataset’s 2026-11-09 update. The 2025 count is the named index because it is a complete calendar year. 2026 is year-to-date as of the update date, not a forecast.

Five of those 364 2025 plumbing permits have a description containing leak, repipe, re-pipe, reroute, under slab, or slab leak: PMT25-07508 (re-pipe 2 bath mobile home), PMT25-11275 (repipe shower conversion), PMT25-12645 (emergency repair for leaky water pipes), PMT25-15286 (toilet leaking), and PMT25-19348 (reroute existing copper domestic cold-water line due to slab leak). Stopping a leak without replacing concealed pipe does not always require a Mesa permit, so this is a permit count, not a leak census. The SODA query, year counts, and the 364-row table are in seo-experiment/data/stat-pages/phoenix/.

What this count is not

A plumbing permit is not a locate. Mesa is one Valley city, not Phoenix, Scottsdale, or Gilbert. Shower conversions, gas lines, and water-service taps are inside the 364 and are not slab leaks. This page does not convert the 364 into a leak rate or a typical repair bill.

Phoenix and Scottsdale winter sewer windows still decide how a leak can change next year’s sewer volumetric charge. Those rules are quoted above; they are not the index. A spinning meter still needs a locate — hot-water slab leak or reroute versus spot repair — before anyone should talk about opening the slab. Typical locate-fee ranges mentioned elsewhere on this site are market talk, not figures from Mesa Open Data.
