Liscomb does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
Private sewage disposal systems (septic) on land inside Liscomb city limits, Marshall County, Iowa. The Marshall County board of health (through the county sanitarian) is the administrative authority under state rule for PSDS, and no Liscomb city septic ordinance was located, so this county authority applies inside the city.
““administrative authority” means the department or the local county board of health as authorized by iowa code section 455b.172 and chapter 137.”

We looked and could not find an official answer yet. Silence is not permission; ask Liscomb or Marshall County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Liscomb publishes no rule on the point, not that none exists. Marshall County’s page lists the county offices to call.
