Permitting an attached or converted ADU in Moreno Valley
In Moreno Valley the drawings are only half the job. The city's checklist ends with a page of acknowledgements, and most of them describe something another office has to sign off before your permit can be issued.

Key points
Which checklist this is
Moreno Valley's "Minimum Plan Submittal Requirements" checklist covers ADUs that are attached to the house or garage, or made by remodeling the inside of the house or garage.1 It carries a revision date of June 5, 2025.1 SB 9 projects are sent to a different checklist run by the Planning Division.1
If you are building a separate detached unit, confirm with Building and Safety which checklist applies before relying on this page.
Before you upload anything
The first box on the list isn't a drawing. You need a valid new city address for the ADU, and the city-approved address letter is one of the required attachments.1 Request the address early, because the title sheet has to show it too.
How the upload works
Submittal is through the city's SimpliCITY portal, and the checklist is particular about it:
- All plan sheets are merged into one PDF file.1
- Each upload has to be given the correct document type.1
- Sheets should follow the city's standard order and numbering. If they don't, SimpliCITY sorts them automatically, and your approved set will come back in a different order from the one you drew.1
- The completed checklist and its acknowledgement pages are uploaded with the application.1
Drawing details that are easy to miss
- Title 24 energy calculations need the required signed sheets printed onto the plan sheets, not attached loose.1
- Truss calculations can't be deferred when the roof isn't conventionally framed.1
- Exterior elevations show where the illuminated address numbers will go.1
- The site plan shows drainage with arrows running away from the foundation.1
- If solar is required, it is a separate plan and permit, yet the proposed panel layout must still be drawn on the building plans.1
The five things due before issuance
Plan approval and permit issuance are different moments in Moreno Valley. The acknowledgement page lists what stands between them:
- Covenant. A covenant agreement between the owner and the city must be completed.1
- Special Financing Districts. Separate fees are required for any new dwelling unit.1
- School district. Fees and certification from the applicable school district.1
- Water and sewer. The owner contacts the purveyor and completes its requirements.1
- Septic, where it applies. Approved health plans from Riverside County Environmental Health are forwarded to the city.1
State law bars impact fees on ADUs of 750 square feet of interior livable space or less.2 Whether a particular district charge falls within that rule is a question to put to the district in writing; this page doesn't answer it.
Work that needs its own permit
Two items are routinely folded into ADU drawings and bounced back:
- A dual meter or main panel upgrade replacing the house's meter needs a separate electrical-only permit, filed under the house address.1
- Exterior work on the existing house, such as walls, patio covers or decks, needs a separate plan and permit.1
Our read
Start the outside clearances the week you submit, not the week your plans are approved. The covenant, the school district certification and the water and sewer release each run on someone else's timetable, and any one of them can hold a permit that is otherwise ready.
Common questions
Do I need an address for the ADU before I apply in Moreno Valley?
Can a panel upgrade go on the same permit as the ADU?
Does Moreno Valley charge fees on a small ADU?
