Summary
Sunnyvale requires a city engineer-issued encroachment permit before anyone builds, plants or places anything in the public right-of-way, under Municipal Code Section 13.08.030. Unpermitted encroachments are a public nuisance the city can abate, and owners with unpermitted work in place before the chapter's effective date had to apply by April 1, 1995 or risk removal.
(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. (b) Encroachment permits shall be issued by the city engineer upon such conditions the city engineer deems necessary to protect the public interest, safety and welfare.
Full Breakdown
Section 13.08.030 of the Sunnyvale Municipal Code makes it "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," with permits issued "upon such conditions the city engineer deems necessary to protect the public interest, safety and welfare." An encroachment permit's obligations run with the property and bind subsequent owners (SMC 13.08.030(c)). Chapter 13.08 exempts several activities from the permit requirement: unenclosed downtown specific plan uses with a special development permit, trees covered by a Chapter 13.16 planting permit, tree-easement landscaping, marquees and awnings that comply with the building code, temporary signs under Chapter 19.92, fences or hedges permitted under Section 19.48.020, newsracks, city crews, and emergency street cuts by a utility (SMC 13.08.040).
Applicants must submit the work's location, purpose and duration, a certificate of insurance, and any required Public Utilities Commission consent (SMC 13.08.060). Before a permit issues, the applicant must carry commercial general liability insurance, at least $500,000 combined single limit for excavations deeper than six inches and $300,000 for shallower or non-excavation work, naming the city as an additional insured (SMC 13.08.070), plus a surety bond filed with the city engineer (SMC 13.08.080). The city can suspend or revoke a permit for violations, unpaid fees, or safety impacts after a ten-day-notice hearing before the Director of Public Works (SMC 13.08.450, 13.08.470).
Violations & Fines
Encroaching without a permit is a misdemeanor punishable under Chapter 1.04, with each day of violation a separate offense, and the city may also pursue civil penalties up to $1,000 per day plus its attorney's fees and costs under Section 13.08.480. An unpermitted encroachment is a public nuisance the city can abate under Chapter 9.26, and existing unpermitted work not brought into compliance risked city removal after 30 days' written notice.
