Do you need a building permit in Monticello, Utah?

Monticello requires a building permit before new construction, additions, remodeling or demolition, and before moving a trailer or pre-built home onto a lot.¹ Obtain the building permit from the city Building Official before starting work.⁶ Starting early triggers an investigation fee equal to the building permit fee, in addition to the building permit fee itself.¹

Monticello applicants must have the property deeded in their name and recorded in San Juan County, or supply a notarized statement granting permission from the legal owner.¹

Does Monticello have zoning, and what about setbacks?

Monticello has city zoning, with permitted uses determined by district under the city code.² Monticello lists residential R-1 and R-2, agricultural A-1, commercial C-1 and C-2, industrial I-1 and government G-1 districts.⁷ The city directs applicants to its zoning map to identify the district and to its city code for building parameters and setbacks.⁸

Before buying, ask Monticello Building and Zoning for the parcel’s district, permitted use, minimum lot area, dwelling size, setbacks and height limits; we could not confirm those dimensional standards here.⁸

How do septic permits work inside Monticello?

San Juan Public Health inspects and permits all septic wastewater systems in San Juan County, including systems inside Monticello.³ San Juan Public Health also maintains septic records and provides them to residents on request.³ Ask that office for existing system records before relying on a seller’s description of a septic installation.³

For wastewater covered by Utah’s onsite rule, connection to public sewer is required when available and practicable; otherwise an adequate onsite system or another acceptable wastewater system is required.⁵ Ask the city about sewer availability before planning a septic system.⁵

Can you live in an RV or tiny home in Monticello?

We could not confirm Monticello’s rules for living in an RV on a private lot, temporary camping while building, or tiny-home occupancy; ask Monticello Building and Zoning about the proposed use and parcel district.⁸ Monticello’s requirement for a building permit before moving a trailer or pre-built home onto a lot does not establish permission to occupy that structure in every zone.¹²

Utah’s tiny-house provisions for RV parks apply to that setting, while permission outside RV parks depends on local land-use rules and the structure’s classification.⁹

Building a home in Monticello: what are the steps?

Start by identifying the Monticello parcel’s zoning district on the city map and asking Building and Zoning whether the proposed home fits the district.⁸² Resolve public sewer availability or contact San Juan Public Health about onsite wastewater before committing to a sanitation plan.⁵³

Submit scaled plans, the legal description, parcel number and a signed building permit application listing contractors; the Building Official may require plans stamped by a Utah architect or engineer.⁶ A qualifying owner-builder must submit the Owner Build Certification and Agreement before construction and still obtain the city building permit.⁴ Obtain the building permit before starting work.⁶

What should you check before buying land in Monticello?

Confirm that the parcel lies inside Monticello before using the city’s building permit and zoning answers; for land outside the city, consult the San Juan County guide for the unincorporated-area rules.¹¹⁰ Ask Monticello’s Building Official about current building permit fees, inspections and occupancy approval, which we could not confirm here.¹¹

For a proposed driveway or local-street connection to a Utah state highway, a UDOT conditional access permit is required; changes in land use or access intensity can also trigger that requirement.¹² Do not treat city building approval as the highway access decision.⁶¹²

Watch-outs

• Monticello’s owner-builder provision concerns acting as your own contractor for a qualifying personal residence; it does not waive the city building permit.⁴
• We could not confirm Monticello’s RV living, tiny-home or temporary camping rules; ask city Building and Zoning before buying land for those uses.⁸
• Starting construction in Monticello before obtaining a building permit adds an investigation fee equal to the building permit fee.¹
