Who permits septicLocal (with conditions)
Septic (SSTS) program for land inside Rosemount city limits that is not served by city sewer
The city page describes the SSTS program and directs questions to the city Chief Building Official.
Designers and installers must be licensed by MPCA (state licensing), so the program is not wholly local.
Whether Dakota County or a health district has any role was not verified in this run.
“all septic systems require a maintenance permit every three (3) years which is issued by the building department.”
Septic permitRequired
New septic systems and building expansions or additions on lots outside the area served by Rosemount city sewer
Systems must be designed and installed by a business licensed by MPCA (city septic page, same source).
The city septic page also discusses a septic maintenance permit; the retrieved text was truncated there, so no maintenance-permit terms are stated in this claim.
“a building permit is required for all new systems on lots developed outside the area served by the city sewer system, and also for building expansions, additions, etc.”
Mandatory utility hookupConditional
New single-unit dwellings inside Rosemount city limits that are not connected to the municipal sewer system
Such dwellings are permitted only when the requirements for private on-site sewer systems have been satisfied (see septic claims).
The retrieved text does not state a distance-to-sewer or mandatory-connection rule.
Water connection requirements were not located in the retrieved text (Title 10 not opened).
“sewer and water, single-unit dwellings: single-unit dwellings which are not connected to the municipal sewer system shall be permitted only when the requirements for private on site sewer systems have been satisfied.”
Subdividing landRegulated (with conditions)

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 Rosemount publishes no rule on the point, not that none exists. Dakota County’s page lists the county offices to call.
