Summary
San Ramon limits how long a heavy-duty commercial vehicle can sit on private property in a residential zone: three hours, under Municipal Code Section D3-41(A). The clock stops for active loading or unloading, or when the truck is providing a service to a property on the same block and needs extra time to finish.
A. Parking limit in residential zones. No "heavy duty" commercial vehicle shall be parked for more than three hours on private property in a residential zone except: 1. While loading or unloading goods or materials and the time required to complete the work exceeds the three-hour period; or 2. When the vehicle is parked in connection with and in aid of providing a service to or on a property in the block in which the vehicle is parked and time in addition to the three-hour period is necessary to complete the service. B. Parking limits in non-residential zones. A "heavy duty" commercial vehicle may only be parked on private property within a nonresidential zone when the vehicle is: 1. Parked in an approved off-street parking space or an approved outdoor storage or activity area; 2. Used in connection with and is owned or leased by an approved business located in a nonresidential zone; or 3. The vehicle is loading or unloading goods in connection with a business and is parked for not more than 48 hours.
Full Breakdown
Section D3-41 splits the rule by zone. In a residential zone, no heavy-duty commercial vehicle may be parked on private property for more than three hours, with two carve-outs: the vehicle can stay longer while actively loading or unloading goods that take more than three hours, and it can stay longer if it is on-site providing a service to a property within the same block and finishing the job needs the extra time. In a nonresidential zone, the standard is different and more permissive: a heavy-duty commercial vehicle may be parked on private property only if it sits in an approved off-street parking space or approved outdoor storage/activity area, is owned or leased by an approved business located in that nonresidential zone, or is loading or unloading goods for a business and stays no more than 48 hours.
The section targets where a truck sits when it is not actively working, not travel on public streets, and it applies parcel by parcel rather than to the vehicle's owner. Because the residential-zone limit is measured in hours rather than by a permit, a homeowner or contractor does not need City sign-off to park briefly, but repeated or extended parking beyond the exceptions is what the ordinance is written to stop.
Violations & Fines
A heavy-duty commercial vehicle parked in a residential zone past the three-hour limit, without an active loading/unloading or in-block service justification, is a code violation the City can cite as a private-property parking infraction. In a nonresidential zone, a vehicle without an approved parking space, business affiliation, or a valid 48-hour loading window is likewise out of compliance and subject to enforcement.
