Summary
In unincorporated Santa Cruz County, a detached storage shed needs no building permit if it is 120 sq ft or smaller, one story and 10 feet or less in height, with no electricity, plumbing, or habitable use. Such sheds may sit within 3 feet of side and rear property lines under County Code 13.10.611.
A detached accessory structure less than 120 square feet in size and 10 feet or less in height may be constructed to within three feet of the side and rear property lines, unless a building envelope not based on zoning standards has been established on the parcel for some other purpose, such as a setback from a sensitive habitat or geological hazard.
Full Breakdown
611, lets property owners in unincorporated areas build a detached storage shed without a building permit when every one of the following criteria is met: the structure does not exceed 120 square feet; it is no more than one story or 10 feet in height measured to the top of the roof sheathing; it is not used or rented as a dwelling or habitable space; it contains no electricity or plumbing; it is unheated and not air-conditioned; it has no bathroom (toilet, sink, tub, or shower); it has no kitchen or food-prep facilities; it has no separate utility meter; it is detached from other structures; and it is not located in a riparian corridor, floodplain, or sensitive habitat.
A qualifying shed located entirely within the required rear yard may be set back as little as 3 feet from the side and rear property lines. Once a shed exceeds 120 sq ft or 10 feet in height, or includes electrical or plumbing service, it requires a building permit and must meet the standard setback and height requirements for the zone district. Even permit-exempt sheds must still comply with zoning standards such as setbacks and applicable Coastal Zone rules. Limited plumbing and 100A/220V electrical service can be allowed in larger non-habitable accessory structures with appropriate permits.
Violations & Fines
Installing a shed larger than the permit-exempt thresholds without a permit, adding unpermitted electrical or plumbing, using a shed as living space, or placing it in a protected riparian/floodplain area can result in code-enforcement action, required permits or removal, and penalties under the County Code.
