Herriman City, Utah, describes a local permit route for an internal ADU within a single-family home. The City’s application page lists selected documents and fees, an approximate plan-review period, and a separate approval sequence before the unit may be rented.
File the internal ADU application
The listed application materials include an application, site plan, address photograph, floor plan, and notarized owner affidavit. The City links additional forms and requirements; use the complete current checklist for the actual home and proposed work. Herriman lists a $559 application-review fee. The building-permit fee is additional and varies with the square footage built or remodeled, including walkouts.
The City’s estimated plan-review period is approximately 7–14 business days. This is a review estimate, not a prediction for the entire permit process, corrections, construction, or rental approval. After plan approval, the City sends a final invoice. Payment precedes permit issuance and inspections.
Complete inspections before rental
After construction or renovation, arrange the required inspections. Herriman says the internal unit needs a passed final inspection and a City approval letter before rental approval. A business license is also required before renting. These rental-related steps do not replace other zoning, occupancy, or applicable licensing requirements.
The City warns that work completed before a permit may require removal of finishes so inspectors can examine concealed work. Confirm eligibility, current forms and fees, plan-review status, inspection requirements, and the current rental-approval sequence with Herriman before construction or occupancy.
