Do I need a permit for a shed in Carpinteria, California?
A shed or other detached accessory building in Carpinteria's R-1 zone must meet the zone's front and side setbacks (side yards are 10% of lot width, at least 5 feet; 3 feet in 4-R-1) and the 30-foot height limit. It can go in the rear setback if it is at least 10 feet from the house and covers no more than 40% of the rear yard.
| Front and side setbacks | Same as the district (not in front or side setback) [1] |
| Rear yard placement | Allowed if at least 10 ft from the house and 40% or less of the rear yard [1] |
| R-1 side setback | 10% of lot width, minimum 5 ft [3] |
| 4-R-1 side setback | 3 feet [4] |
| Max height (R-1) | 30 feet [5] |
| Max building coverage (all enclosed buildings) | 35% of net lot area [6] |
| R-1 rear setback | 15 feet [10] |
Where a shed can go
Accessory structures must meet the district's height limit and its front and side yard setbacks. They may sit in the required rear yard setback if they are at least 10 feet from the main house and take up no more than 40% of the rear yard [1]. The general yard rules add that nonhabitable detached structures may be allowed in the rear setback if the Community Development Department finds them compatible with surrounding uses [2].
R-1 setbacks and height
In R-1 districts other than 4-R-1, side setbacks are 10% of the lot width but never less than 5 feet [3], and the rear setback is 15 feet [10]. Front setbacks are 20 feet from the property line or 50 feet from the street centerline, whichever is greater [9]. In the 4-R-1 district (small older lots), the front setback is 10 feet from the property line or 40 feet from the centerline, side setbacks are 3 feet [4] and the rear is 15 feet. No building or structure may exceed 30 feet in height [5].
Corner lots
On a corner lot, an accessory structure can't be closer to the street than the house or sit in any side or front setback [7]. Where a corner lot backs onto a key lot, it must be at least 10 feet from the rear property line [11].
Size and coverage
The code sets no separate size cap for sheds, but all enclosed buildings together may cover no more than 35% of the net lot area [6].
Timing and permits
You can't build an accessory structure until construction of the main house has begun [8]. The local code we reviewed doesn't set a building-permit size threshold for sheds, so the state building code exemption applies (see the state rules section). Because the whole city is in the coastal zone, ask staff whether a coastal development permit is required.

Next steps
- Check your zoning district (4-R-1, 6-R-1, etc.) on the city zoning map to know your setbacks.
- Site the shed outside the front and side setbacks, or in the rear setback at least 10 feet from the house.
- Confirm with the Community Development Department, (805) 684-5405, that the location is acceptable and whether a coastal development permit applies.
- If the shed is over the state permit-exempt size or has electrical or plumbing, apply for a building permit with Building & Safety.

California state rules for sheds and accessory buildings
Where a shed can go (setbacks, height, lot coverage, front-yard limits) is set by your city or county zoning code. The state sets the building-permit baseline:
- Permit exemption: the 2025 California Residential Code (R105.2) exempts one-story detached accessory structures used as tool and storage sheds, playhouses and similar uses if the floor area is 120 sq ft or less. Bigger sheds need a permit, and electrical or plumbing work needs its own permit. Some cities have amended these thresholds.
- Other exempt work in the same list includes fences up to 7 ft and decks up to 200 sq ft that are no more than 30 inches above grade and not attached to the house.
- Exempt doesn't mean unregulated: zoning setbacks, HOA rules and easements still apply, and some cities require a zoning clearance even for small sheds.
- Turning a shed or garage into living space is covered by the state's ADU law (Gov. Code §66314). An existing accessory structure converted to an ADU needs no added setback, and new ADUs need no more than 4-foot side and rear setbacks (see ADUs).
- Wildfire areas: in a state responsibility area, owners must keep 100 feet of defensible space around buildings (Pub. Res. Code §4291). Local fire-hazard rules may limit what you can build or store near structures.
- Coastal zone: a new structure is "development" and may need a coastal development permit (Pub. Res. Code §30106).
