Encanto leads all of San Diego in ADU permit activity — 85 units since 2023, more than any other neighborhood in the city. Tri Express Plumbing has completed 73 ADU plumbing projects across San Diego County since 2024. Family-owned since 2008. CA Lic #926629.
Since 2023, Encanto and the greater Southeastern San Diego area have pulled more ADU permits than any other neighborhood in the city — 85 and counting. It's not a coincidence. Encanto's mid-century homes sit on some of San Diego's larger residential lots, leaving real room for a detached unit without crowding the yard. And with rental income in the neighborhood running $1,500–$2,200 a month for a permitted ADU, the math works for a lot of homeowners here. Tri Express Plumbing has been part of that build-out — 73 ADU plumbing projects completed across San Diego County since 2024.
85 ADU permits since 2023 — more than College Area, Clairemont Mesa, or La Jolla. Encanto is where San Diego's ADU boom is concentrated.
Permitted ADUs in Encanto typically rent for $1,500–$2,200/month, offsetting mortgage costs or funding the build itself over time.
Encanto's mid-century ranch homes sit on larger lots than newer, denser neighborhoods — real room for a detached ADU.

"Encanto's older homes usually have accessible sewer laterals, but the lot depth means longer trenching runs than a newer subdivision. We map utility distance during the on-site visit — it's the single biggest swing factor in final price here."
Encanto's ADU boom means we've mapped utility lines, sewer laterals, and water service on more lots in this neighborhood than almost anywhere else in the county. That experience shows up in more accurate estimates and fewer surprises once digging starts.
Detached units, garage conversions, and JADUs — here's what our team handles on Encanto ADU projects, start to final inspection.
