Do you need a building permit in Milford, Utah?

Milford requires a building permit for construction that physically changes or adds structures to a property, including additions, finishing an unfinished basement, changing a structure’s use, moving or demolishing a building, and listed equipment repairs or replacements.1 Submit Milford building applications online through Beaver County’s Building Department; Milford retains zoning review and building-permit payment.2 Utah’s State Construction Code applies to new construction and specified work on existing buildings, including alterations and changes of use that increase occupancy loads or safety risks.8 Ask the building official which approvals your specific project needs before starting work.9

Who handles Milford building applications and inspections?

For Milford property, Beaver County’s Building Department handles the building application and inspections, while Milford handles zoning and building-permit payment.2 Milford’s building-permit page provides city assistance at (435) 387-2718 and directs inspection scheduling to (435)438-6484.9 Milford building inspections must be scheduled at least 24 hours in advance.9 Keep the city zoning review and county building review together in your project planning: submitting an online building application does not transfer Milford’s zoning responsibilities to the county.2

Does Milford have zoning, and what about lot size and setbacks?

Milford handles the zoning portion of the building-permit process.2 For a proposal going before Milford’s Planning and Zoning Commission, required documents and filing fees must reach the Zoning Administrator by the Wednesday before the meeting.10 Ask the Milford Zoning Administrator to identify your parcel’s district and confirm the proposed use, minimum lot area, setbacks and lot coverage before you commit to a layout.10 We could not confirm a complete district-specific dimensional schedule; ask that office for the standards applicable to your parcel rather than assuming a nearby lot establishes what you can build.10

How do septic permits work inside Milford?

Milford generally prohibits private wastewater-disposal facilities except under its public-system exception; where public sewer is unavailable, state and local-board-of-health requirements apply and a certificate of approval must accompany the building-permit application.46 Southwest Utah Public Health Department administers septic plans, permits, inspections and records for Beaver County.3 A septic permit and approved design are required before installing, replacing or modifying a system, and a Utah-certified onsite professional must complete soil and percolation testing before design or installation.5 Every septic system needs a final inspection before backfilling.11 Confirm sewer availability with Milford before paying for a septic design.4

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

We could not confirm Milford’s rules for residential RV occupancy, temporary camping, tiny homes or manufactured-home occupancy on private lots; ask the Milford Zoning Administrator about your proposed structure and duration of use.10 Utah’s RV-park occupancy rules apply to RV parks, so those rules do not establish permission to live in an RV on a private residential lot in Milford.12 Outside RV parks, tiny-home approval depends on local land-use rules and whether the structure is treated as a primary dwelling, accessory dwelling, modular unit or manufactured home.13 Milford’s wastewater restrictions still matter when planning an off-grid dwelling.4

What are the steps to building a home in Milford?

  • Start with Milford’s Zoning Administrator: confirm the parcel’s zoning and submit required documents and fees by the Wednesday before a commission meeting if your project needs commission review.10
  • Establish the water and wastewater route: Milford requires connection to an abutting public sewer within 180 days after official notice; where public water or sewer is unavailable, health approval must accompany the building application.6
  • File the building application online through Beaver County and arrange zoning review and building-permit payment with Milford.2
  • Schedule building inspections at least 24 hours ahead using the inspection contact on Milford’s building page.9
  • Ask the building official what final approvals are required before moving in; we could not confirm a general Milford certificate-of-occupancy rule.9

What should you check before buying land in Milford?

For land outside Milford city limits, use the Beaver County guide: Beaver County administers zoning and building applications for unincorporated parcels.14 Inside Milford, start with the city’s zoning review and utility requirements.26 A shallow well in Utah requires a valid groundwater right before construction and a Start Card issued upon water-right approval; construction must be performed by an appropriately licensed professional.7 Access along a state highway requires a UDOT conditional access permit for a requested driveway connection or a change in land use or access intensity.15 We could not confirm Milford-specific floodplain or local driveway requirements; ask the Zoning Administrator where to obtain those determinations for your parcel.10

Watch-outs

  • Milford handles zoning and building-permit payment even though Beaver County handles the building application and inspections.2
  • An abutting public sewer triggers Milford’s connection requirement within 180 days after official notice; septic is not a freely interchangeable alternative.64
  • We could not confirm private-lot RV living or tiny-home occupancy in Milford; obtain a determination from the Milford Zoning Administrator before buying for that purpose.10
