Summary
Sunnyvale requires an encroachment permit from the city engineer before anyone obstructs, blocks or places anything in the public right-of-way, including sidewalks, under Municipal Code Chapter 13.08. Unpermitted obstructions are a public nuisance the city can abate, and the code broadly defines encroachment to cover physical improvements, landscaping and waste material left in the way.
§ 13.08.030. Encroachment permit required. (a) Except as otherwise provided in Section 13.08.040, it is unlawful for any person to encroach or to make or to cause to be made any encroachment without first having obtained an encroachment permit from the city engineer... (e) Any encroachment for which a permit is required and for which no permit has been issued pursuant to this chapter shall be deemed a public nuisance which may be abated by the city pursuant to Chapter 9.26. "Encroach" or "encroachment" includes going upon, over or under a right-of-way, or using a right-of-way or an area adjacent to a right-of-way in such a manner as to prevent, obstruct or interfere with the intended use of that way.

Full Breakdown

"Public street" is defined to include sidewalks and the areas between sidewalks and the vehicular travelway.

Violations & Fines
An unpermitted encroachment is a public nuisance the city may abate under Section 13.08.030(e), with removal at the responsible party's expense. Because Chapter 13.08 is not listed among the infraction chapters in Section 1.04.010(b), a violation defaults to a misdemeanor under Section 1.04.010(a), punishable under Section 1.04.020(a) by a fine of not more than $1,000, imprisonment in county jail for not more than six months, or both, with each day of continued obstruction a separate offense.
