Truckee ADU guide: local rules, permits & property planning

What matters for an ADU in Truckee
Permitting authority: Town of Truckee — ADU program
Official local guidanceLocal rules and design checks
| Topic | Local guidance |
|---|---|
| Snow design | The Town’s modular-ADU resource identifies ground snow loads from 170 to more than 480 psf; obtain the parcel-specific design criteria. |
| Site documents | Regional plans still need applicable survey, grading, erosion-control and geotechnical materials. |
| Design licensing | Privately submitted preapproved plans carry fees set by their design professionals. |
Selected local requirements, not a complete zoning determination. Confirm the current rules for your address with the responsible agency.
Fees and budget checks
