Do You Need a Permit for a Shed in Los Angeles? 2026 Rules

Most one-story storage sheds of 120 square feet or less can be built in Los Angeles without a building permit. But "Los Angeles" means two different things here. It depends on where your property actually sits.

If your backyard is inside city limits, the agency is the Los Angeles Department of Building and Safety. The exemption covers detached structures used only for tools, garden equipment, and storage.

If you are in an unincorporated pocket that still uses a Los Angeles mailing address, the rules come from LA County Public Works, Building and Safety. The county allows the same 120 square feet, but setbacks, hillside lots, and any electrical or plumbing you run out there can still put you back in permit territory. Read on and check which one covers your address, then you can choose a suitable shed size.

Which “Los Angeles” Are You In?

A Los Angeles mailing address does not necessarily mean the property is inside the City of Los Angeles. Unincorporated communities may use a city name in their postal address, even though the County is their planning and permitting authority. LA County Planning advises owners to use its jurisdiction lookup tools rather than relying on the mailing address.

ZIMAS provides zoning and planning information for City property. GIS-NET Public provides parcel, planning, and zoning information for unincorporated County territory. County records identify Altadena, Hacienda Heights, View Park–Windsor Hills, and East Los Angeles as unincorporated communities.

Check the parcel before applying any rule below. This simple step can prevent you from following the right rulebook for the wrong jurisdiction.

Why 120 Square Feet?

Your HOA did not pick that number. It comes from the building code, and the city and the county both use it. A one-story shed at or under 120 square feet with no utilities running to it counts as low risk, so the building department skips plan check. Your HOA sits on top of that as a separate layer. It can set stricter rules on color, height, and placement through your CC&Rs, but it cannot issue or waive a permit.

City of Los Angeles

The building code exempts a one-story detached accessory structure when the floor area is 120 square feet or less. That covers a tool house, storage shed, playhouse, or similar use.

Three conditions come with it:

• The shed cannot sit in Fire District No. 1, the high-restriction zone the city defines in Division 72 of its building regulations. Look up your parcel on ZIMAS to see whether you are in it.
• No heating, plumbing, or electrical installations.
• Placement has to follow zoning.

Unincorporated Los Angeles County

A one-story detached tool or storage shed skips the building permit only when it meets all three limits:

• Gross floor area of 120 square feet or less
• Height of 12 feet or less
• Roof projection of 24 inches or less

The county adds that you may still need separate electrical, plumbing, or mechanical permits, and that zoning and other laws still apply.

Permit-exempt does not mean code-exempt. It only means the building department will not run your shed through the normal permit and plan-check process. The shed still has to meet code.

What 120 Square Feet Actually Looks Like

Common footprints at or below the threshold include:

• 10 by 12 feet = 120 square feet
  
• 8 by 14 feet = 112 square feet
  
• 10 by 10 feet = 100 square feet
  
• 8 by 12 feet = 96 square feet

Measure the actual floor area. Do not assume a product marketed as a “10-by-12 shed” will always have code dimensions that land at exactly 120 square feet. For County projects, also check overall height and eave projection.

Permit-Exempt Does Not Mean Rule-Exempt

The most common mistake is choosing a shed by size and its location by convenience. Size is only the first test. Placement is often the harder one.

Setbacks of the Shed and Base Location

A setback is the required distance between a structure and a property line, street, or another structure.

There is no single "Los Angeles shed setback" that works for every property. The distance can depend on the zone, lot configuration, street frontage, existing buildings, community standards district, specific plan, or another parcel condition.

LA County's enforcement guidance confirms that outdoor structures can violate required side and rear yards even when the structure itself is otherwise allowed. In the City, check your parcel on ZIMAS against the current zoning code. Do not rely on a neighbor's shed or a general number found online.

Shed Height and Lot Coverage

Height limits apply independently from the permit exemption. Check how the jurisdiction measures height and whether roof features count. City zoning provisions often regulate the highest point of a roof or structure, not the eave line.

Lot-coverage and residential floor-area rules may also count accessory buildings. A shed that fits in the yard can still push the parcel over a development limit.

Easements and Overlays

Do not place a shed over a recorded utility, drainage, access, or sewer easement without clearance from the party that controls it.

City parcels may also fall under hillside regulations, the Baseline Mansionization Ordinance, a Historic Preservation Overlay Zone, a specific plan, or coastal rules. ZIMAS surfaces most of these parcel-specific conditions in one place.

The practical rule is simple. Confirm the location, not just the size.

When You Definitely Need More Review

Contact LADBS or County Building and Safety before construction when:

• The shed is larger than 120 square feet.
• You plan to install lighting, receptacles, a subpanel, hard-wired equipment, plumbing, drainage, heating, or mechanical ventilation.
• The project involves substantial grading, retaining work, a large slab, engineered footings, or construction on a slope.
• The parcel is in a hillside, fire-hazard, coastal, historic, or other specially regulated area.
• The building will be used for more than ordinary storage.

A workshop or backyard office is not automatically an ADU, but it will not be treated like a simple storage shed either. Its intended occupancy can trigger structural, energy, ventilation, electrical, or sanitation requirements. Once the space is designed for sleeping, cooking, or independent living, the project moves into ADU and dwelling-unit rules.

Do not pour a foundation before you confirm the project. Neither exemption requires a permit for the foundation itself, but grading, utility, and site conditions around it can each trigger one.

Your HOA Is a Separate Approval

Municipal approval and HOA approval are independent. LADBS or the County can accept a shed your HOA prohibits, and your HOA can approve a design that still violates zoning.

HOAs commonly regulate exterior color, siding, roofing, street visibility, screening, and whether the shed has to match the house.

If you are not sure what yours allows, read your CC&Rs first, then the HOA shed and architectural approval rules that most Los Angeles area associations share, and bring a design that already fits.

California associations that enforce architectural restrictions have to keep written review procedures with a stated maximum response time under Civil Code section 4765. There is no universal statewide 30 or 45 day approval window for an ordinary shed.

For planning purposes, budget at least one full review cycle, often 30 to 45 days, but follow the deadline and meeting schedule in your own governing documents. Submit before you buy a nonreturnable kit.

How to Apply for a Shed Permit in Los Angeles

Step 1: Confirm the jurisdiction. Use ZIMAS for City property, or GIS-NET and Z-NET for unincorporated County property.

Step 2: Prepare a site plan. Show property lines, the house, existing structures, the proposed shed, dimensions, and distances to property lines.

Step 3: Prepare construction documents. A larger or more complex shed may need framing details, foundation information, calculations, or professional drawings.

Step 4: Submit through the correct portal. LADBS uses Express Permits for eligible no-plan-check work and ePlanLA for plan review. LA County uses EPIC-LA.

Step 5: Complete plan check and corrections.

Step 6: Schedule inspections. Do not cover work before a required inspection

FAQs

Can I Put a Shed in My House in Los Angeles without a Permit?

Usually, yes, when it is a qualifying one-story storage shed no larger than 120 square feet. Conditions differ between the City and County, and zoning still controls its location.

How Close to the Fence can a Shed be in LA?

There is no reliable citywide or countywide answer. Setbacks vary by zoning, parcel configuration, community standards, overlays, and sometimes the relationship to other buildings. Check ZIMAS or GIS-NET and confirm the result with the appropriate planning counter.

Do I Need a Permit for a 10-by-12 Shed in California?

A true 10-by-12 footprint is 120 square feet, so it may qualify for the Los Angeles exemption. In the City, it must also be outside Fire District No. 1, have no heating, plumbing, or electrical installation, and comply with zoning. In unincorporated County, it must also stay within the 12-foot height and 24-inch roof-projection limits.

What Happens if I Build a Shed without a Required Permit?

The jurisdiction may require after-the-fact permits, exposure of concealed work, modification, relocation, or removal. The City also authorizes investigation and additional fees for work performed without a required permit.

Does a Shed Increase Property Taxes in California?

It can. California generally treats qualifying new construction as assessable and adds the value of the new improvement—not necessarily the entire property—to the tax base. A small movable shed may be treated differently from a permanent improvement. Permit exemption does not automatically create a property-tax exemption.

Check the Rules Before You Buy the Shed

The 120-square-foot rule is useful, but it is not the whole answer. Start by identifying whether LADBS or LA County has jurisdiction over your address. Then confirm setbacks, height, lot coverage, easements, overlays, utilities, and HOA approval.

Los Angeles is only one set of rules. Cities elsewhere in the state set their own limits, and the California shed permit rules vary enough that a shed exempt in your backyard can need a permit an hour up the freeway.[CTA slot 2: Shop Terkkin sheds by footprint, storage capacity, and Los Angeles permit-planning needs.]
