Summary
Ontario bars parking or storing vehicles, trailers and boats on a lawn, landscaped area or any other unpaved surface in a residential lot's front or street-side yard, and holds the property owner liable right alongside whoever actually parked there.
It is unlawful for any person to park any vehicle, including but not limited to automobiles, trucks, motor homes, campers, or store any trailer, camper shell, boat or other similar equipment upon any lawn or landscaped area, or other unpaved surface located within any front or street side yard area of a lot lying within any residential zoning district, or any residential land use district of a specific plan or planned unit development, or any other property zoned or used for residential purposes. ... This section shall not be so construed as to prohibit the parking of vehicles on lawns or other unpaved surfaces for the purposes of washing, making emergency repairs, or on-site construction when the parking does not exceed a total of 3 hours duration within any consecutive 24-hour period.

Full Breakdown
Sec. 03(a) makes it unlawful for anyone to park a vehicle, including trucks, motor homes and campers, or to store a trailer, camper shell or boat, on a lawn, landscaped area or other unpaved surface within a front or street-side yard of a residentially zoned lot. Sec. 03(b) separately makes it unlawful for a property owner to permit that same parking or storage, and Sec. 03(c) bars using an unpaved area purely as a driveway to reach a parking spot, though the Planning Director may grant an exception where the access is so infrequent it causes no discernible landscaping damage.
Sec. 03(d) clarifies the section does not authorize paving over a front or side yard; any added paving needs Planning Department approval of its location and size. Sec. 03(e) carves out a narrow window: vehicles may sit on a lawn or unpaved surface for washing, emergency repairs, or on-site construction work for up to three hours in any 24-hour period. Sec. 02 imposes the parallel ban on undeveloped or unpaved nonresidential lots. Sec. 01 defines pavement as an all-weather asphalt, concrete, or paver surface and landscaped area as planted ground cover, walkways, patios or similar features.
Enforcement runs through Sec. 05, which lets a peace officer or code enforcement officer enter private property to cite a violation under Vehicle Code § 40202.
Violations & Fines
Sec. 4-13.06 makes any violation of the Chapter 13 parking rules, including the front-yard unpaved parking ban, subject to fines and civil penalties set and amended by resolution of the Ontario City Council rather than a fixed statutory amount, and a code enforcement officer or peace officer may enter the property under Sec. 4-13.05 to issue the citation.
