Jurisdiction and research scope
City of Union City, California only, not Union Township or Union City in another state. Chapter 10.35 applies different size, nonmotorized, overnight and residence-district rules. A postal address is not a jurisdiction determination. This guide does not establish HOA, lease, fire, traffic-sign, building or utility approval.

| Location or use | What to check |
|---|---|
| Street size and overnight restrictions | Section 10.35.020 defines a large vehicle as both over six feet high and over 20 feet long, or over 8.5 feet wide. Section 10.35.030 prohibits large vehicles on city streets from 2 a.m. to 6 a.m.; nonmotorized vehicles have a separate prohibition during those hours. Police may grant qualifying frontage loading, unloading or trip-service exemptions for no more than 24 hours immediately before or after a trip. They are discretionary, not automatic. Other authorized emergency and reasonable-need exemptions and sole-vehicle variances have distinct requirements. Reasonable-need exemptions normally last up to 72 hours, with unusual-hardship extensions up to 15 days and no more than two exemptions for a vehicle and location or substantially similar location in 365 days. The A(1) exemptions or variances cannot be issued for a street no more than 30 feet curb to curb. Recreational nonmotorized trailers have the specific A(2)-based exception; do not extend all large-vehicle exceptions to them. |
| Residence-district storage and obstruction | Section 10.35.040 applies to large and nonmotorized vehicles in residence districts as defined by California Vehicle Code §515. Front-yard placement must be on a driveway or approved extension. Such vehicles cannot serve as accessory structures, living or sleeping space, housekeeping space or storage for goods beyond their intended purpose. Confirm the statutory district rather than assuming a zoning label is equivalent. Section 10.35.050 prohibits sidewalk overhang or blockage. Section 10.35.060 limits extension to 8.5 feet from the curb face and prohibits overhanging or blocking the public right-of-way, subject to its authorized-emergency exception. Being under the size threshold does not waive other traffic rules. |
| Sleeping, permits and uncertain cases | Residence-district sleeping and living restrictions are separate from street parking. A loading permit does not authorize habitation or hookups. Smaller self-propelled vehicles outside the large-vehicle definition, locations outside the statutory residence district, enclosed structures and maintenance need other applicable rules. The checker does not approve them by omission, and it does not issue or presume a police exemption. |

Who to contact for your setup
Ask the city planning or enforcement office to confirm the parcel, current amendments and any required authorization before relying on an exception.
Use the Union City parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
