Do you need a building permit in Mona, UT?

Mona requires building permits for building construction inside city limits and takes applications online.1 Mona’s building-permit checklist calls for plans, a deed, a plat, a site plan, culinary-water documentation and the other listed uploads.1 Submit a complete application at least two weeks before the Planning and Zoning meeting; late applications may wait until the following month.1 Treat water documentation as part of the application preparation, rather than something to resolve after submitting the plans.1

Who handles building permits and zoning in Mona?

Mona City Planning and Zoning makes recommendations to the City Council on building permits, accessory building permits and annexations.7 Call the city at 435-623-4913 for building-permit review and zoning questions inside Mona.7 Mona’s Planning and Zoning Commission meets on the first Wednesday of each month at 7:30 p.m.8 Plans requiring an inspection are due two weeks before the meeting, while other paperwork is due one week before review.8 Onsite wastewater questions go separately to Central Utah Public Health Department, which serves Juab County.3

Does Mona have zoning, minimum lot sizes and setbacks?

Mona maintains city planning and zoning and publishes an interactive city zoning map.2 Mona’s published Residential Development Standards list a minimum lot size of 0.5 acre, but do not identify the zoning district to which those standards apply.4 The residential checklist lists front and rear setbacks of 30 feet and side setbacks of 10 feet; corner lots need 30 feet on every side fronting a street.5 The same checklist lists a height limit of 35 feet or 2.5 stories and says the structure must be taller than 10 feet.9 Ask Mona City Planning and Zoning to confirm the parcel’s district and applicable standards before choosing a house footprint.25

How do septic permits work inside Mona?

For a Mona property needing onsite wastewater treatment, Central Utah Public Health Department is the septic authority for Juab County.3 Utah’s wastewater rule requires connection to public sewer when available and practicable; an adequate onsite system or another acceptable wastewater system is required when sewer is unavailable or impracticable.10 Ask Mona City about sewer availability before budgeting for septic.10 Central Utah Public Health Department requires a construction permit before any portion of a septic system is built, with soil classification, a site plan and system design among the application materials.6 The 2026 permit packet lists $600 for a conventional system, $900 for an alternative system and $200 for repair or replacement.6 The health department’s permit process requires inspection before backfilling.11

Can you live in an RV or tiny home on land in Mona?

We could not confirm Mona’s rules for residential RV occupancy, temporary camping, tiny homes or manufactured-home occupancy on private land; take the intended use to Mona City Planning and Zoning before committing to a purchase.2 Utah’s tiny-home information says permission in a particular area depends on local land-use regulations.12 Rules for temporary stays in an RV park do not establish permission to live in an RV on a private Mona lot.13 We also could not confirm Mona’s minimum dwelling size or alternative off-grid sanitation permissions; ask the city about the dwelling and Central Utah Public Health Department about sanitation.23

Building a home in Mona: what are the steps, in order?

  1. Ask Mona City Planning and Zoning to identify the parcel’s zoning district and confirm which residential lot and setback standards apply.245
  2. Prepare the building plans, deed, plat, site plan and required culinary-water documentation for the online building-permit application.1
  3. Resolve sewer availability; if onsite treatment is needed, obtain Central Utah Public Health Department’s septic construction permit before installation.106
  4. Submit the city building-permit application at least two weeks before the Planning and Zoning meeting and follow the review email identifying approval and the review date.18
  5. Ask Mona City about the required building inspections and certificate of occupancy before arranging a move-in date; we could not confirm the city’s occupancy procedure.7

What should you check before buying land in Mona?

If a Mona purchase involves dividing land, the city defines a minor subdivision as 3 lots or fewer with no new roads; more lots or new roads trigger the major-subdivision process.14 Mona’s major-subdivision process requires separate preliminary and final applications and review by the Development Review Committee and Planning and Zoning Commission.14 For a proposed shallow well, Utah requires a valid water right before construction and a Start Card issued after water-right approval, with construction by an appropriately licensed professional.15 Confirm whether the land is inside Mona before selecting the building-permit office; county building authority applies to unincorporated land, and the Juab County guide covers that setting.16

Watch-outs

  • Mona’s residential checklist does not name a zoning district; confirm applicability before treating the 0.5-acre lot minimum as the answer for a particular parcel.4
  • A Mona building-permit application received after the submission deadline may be deferred until the next month’s meeting.1
  • We could not confirm a Mona-specific floodplain administrator or driveway-access procedure; ask Mona City Planning and Zoning who reviews the proposed site and access.2
