Hanford's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Hanford, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

ADU Rental Restrictions

Hanford requires accessory dwelling unit rentals to run longer than 30 days, ruling out short-term rentals of ADUs, and separately bars selling or conveying an ADU apart from the primary residence under Municipal Code § 17.60.030(A)(16)-(17), tracking the limits state ADU law imposes.

Key details: Minimum rental term: Longer than 30 days (no short-term rentals). Separate sale: Prohibited; ADU cannot be conveyed apart from house. Condo conversion: Barred except narrow Gov. Code § 66342 exception. JADU owner-occupancy: Required unless held by public/nonprofit housing entity. Governing section: Hanford Municipal Code § 17.60.030(A)(16)-(17).

Renting an ADU on a term of 30 days or less, or selling or otherwise conveying an ADU separately from the primary residence, violates § 17.60.030(A)(16)-(17) and is enforced as a zoning violation under the Municipal Code's general penalty, § 1.20.010: an infraction punishable under Government Code § 36900(b), treated as a public nuisance subject to City abatement, with each day of a short-term rental or unlawful conveyance counted as a separate offense.

This is not one of those rules that cities tend to ignore. Hanford actively enforces its adu rental restrictions requirements.

Shed & Carport Rules

Hanford limits accessory structures placed in a required side or rear setback to 120 square feet in the R-L-5, R-L-8, and R-L-12 zones, with wall, eave, height, and separation limits.

Key details: Max floor area in setback: 120 sq ft. Wall clearance: 3 ft from lot lines. Plate-line height cap: 7 ft. Separation from buildings: 10 ft minimum. Zones covered: R-L-5, R-L-8, R-L-12.

A shed over 120 square feet, or one that violates the wall, eave, height, or separation limits while sitting in a required setback, is a zoning violation; Code Enforcement can order it relocated or removed and cite the owner for an infraction.

ADU Rules

Hanford's accessory dwelling unit standards set a four-foot side and rear setback and cap detached ADU height at 16 to 25 feet depending on lot type and transit proximity under Municipal Code § 17.60.030(A)(5)-(6), but state ADU law, Gov. Code § 66310 et seq., controls whenever it conflicts with the local rule.

Key details: Side/rear setback: 4 feet from lot line. Front setback: Follows underlying zone district standard. Detached ADU height: 16 ft standard; 18 ft near transit. Attached ADU height: 25 ft or zone limit, max 2 stories. State law controls conflicts: Gov. Code § 66310 et seq. overrides local rule.

An ADU built without the required site plan review or that doesn't meet the four-foot setback, height, or size standards is enforced the same as any other zoning violation: it is an infraction under the Municipal Code's general penalty, § 1.20.010, punishable under Government Code § 36900(b), and the code treats the condition as a public nuisance subject to abatement, with a separate offense accruing for each day it continues.

ADU Owner Occupancy

A Hanford junior accessory dwelling unit requires the owner to occupy either the primary home or the JADU itself, unless the owner is a public agency or housing nonprofit.

Key details: Applies to: JADUs, not standard ADUs. Requirement: Owner occupies house or JADU. Exception: Public agency, land trust, housing org. Recorded: Deed restriction required at approval.

Creating a JADU without owner-occupancy of the property, absent a qualifying government or nonprofit owner, violates § 17.60.030(B)(8) and can void the JADU approval.

Garage Conversions

Converting a Hanford, California garage or carport into living space needs site plan review approval, a matching exterior, buffering, and two replacement parking spaces.

Key details: Zoning required: Single-family or mixed-use. Replacement parking: 2 spaces, 9 x 18 ft. Garage door: Removed or walled over. Approval path: Site plan review.

Converting a garage without site plan review approval, or failing to provide the required replacement parking or exterior treatment, is a code violation and can require restoring the space to vehicle parking use.

The Bottom Line

Hanford's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Hanford is broadly strict or permissive.

Keep in mind that Hanford can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
