Fences & Walls
Some RestrictionsHeight limits, materials, permits, and shared fence rules.
Permit Requirements
Some RestrictionsDavis reviews fences for zoning compliance under Municipal Code 40.27.060, and the city Building Division issues building permits for construction; taller walls and fences on retaining walls can trigger permit and design-review requirements.
Approved Materials
Few RestrictionsDavis Municipal Code 40.27.060 regulates fence height and placement rather than prescribing specific materials; height is measured to the highest point of the fence, wall, or hedge on the high side.
Height Limits
Some RestrictionsDavis Municipal Code section 40.27.060 caps fences, walls, and hedges at seven feet behind the required front yard setback, four feet in any required yard, and six feet at the reduced front and street-side setbacks.
Neighbor Fence Rules
Some RestrictionsDavis Municipal Code 40.27.060 sets where and how tall boundary fences may be, but it does not assign shared-fence cost or maintenance; those disputes fall under California's Good Neighbor Fence Act (Civil Code 841).
Retaining Walls
Some RestrictionsDavis Municipal Code 40.27.060 measures a fence on top of a retaining wall from the lowest existing grade within a three-foot radius to the highest point of the fence on the high side of the wall.
Swimming Pools
Heavy RestrictionsPool permits, safety fencing, and drainage requirements.
Above-Ground Pools
Some RestrictionsThe Davis checklist expressly covers above-ground pools, requiring three plan or manufacturer-specification sets and the same 5-foot setback and drowning-prevention rules as in-ground pools. Barrier and safety-feature requirements apply once the pool holds water more than 18 inches deep.
Fencing Requirements
Heavy RestrictionsA Davis pool or spa must be isolated by an enclosure meeting California Health and Safety Code Section 115923: at least 60 inches high, no more than a 2-inch gap at grade, no opening passing a 4-inch sphere, and gates that self-close, self-latch, and open away from the pool.
Safety Rules
Heavy RestrictionsBeyond the isolation enclosure, Davis pools and spas must include at least two of seven drowning-prevention safety features listed in the city checklist and California Health and Safety Code Section 115922, and all required devices must be in place before the pool is filled.
Pool Permits
Some RestrictionsDavis requires a building permit for in-ground pools, spas, and above-ground pools. Plans, setbacks, and a signed/sealed steel schedule for gunite work are submitted to Community Development and Sustainability. In-ground pools also need a Public Works encroachment permit.
Hot Tub Rules
Some RestrictionsDavis regulates spas alongside pools: manufactured spas must be listed, spa submittals must include electrical and gas requirements, and outdoor pools or spas equipped with a gas or electric heater must have a pool/spa cover. Spas also meet the same 5-foot setback and drowning-prevention rules.
ADUs & Granny Flats
Few RestrictionsAccessory dwelling unit rules and garage conversion permits.
ADU Rules
Few RestrictionsDavis regulates accessory dwelling units under Davis Municipal Code Section 40.26.450, implementing California state ADU law (Government Code Sections 66310 through 66342). A detached ADU of 800 square feet or less, no more than 16 feet tall, with 4-foot side and rear setbacks is deemed consistent with all city standards.
Garage Conversions
Few RestrictionsConverting a garage into living space or an accessory dwelling unit in Davis is governed by the ADU provisions in Davis Municipal Code Section 40.26.450 and state ADU law. When a garage or carport is converted to an ADU, the city may not require replacement of the displaced off-street parking.

Some RestrictionsShed permits, setback limits, and outbuilding size rules.

Some RestrictionsDavis regulates accessory structures, including storage sheds, through its zoning code (Chapter 40) and published Accessory Structure Development Standards. A small storage shed no larger than 120 square feet may sit within the required rear and interior side yard setbacks.
Carport Rules
Some RestrictionsCarports and covered parking structures in Davis are regulated as accessory structures under the zoning code (Chapter 40) and must meet the same setback and height standards. Under state ADU law, a carport converted to or demolished for an accessory dwelling unit does not require replacement parking.
Tiny Homes
Some RestrictionsDavis does not have a standalone tiny-home ordinance; a tiny home on a permanent foundation is regulated as an accessory dwelling unit under Davis Municipal Code Section 40.26.450, while a tiny home on wheels is treated as a recreational vehicle and generally may not be used as a permanent dwelling.
Fire Pits & Outdoor Structures

Fire Pit Rules
Some RestrictionsDavis has no separate backyard fire-pit ordinance; residential fire pits follow the 2022 California Fire Code adopted in Article 13.01. On public property, Article 13.03 governs recreational fires with a permit and a 15-foot clearance. Only clean cooking fuels may be burned.

General Permit Tips
When do you typically need a permit?
Most cities require permits for structural work, including fences over a certain height, pools, ADUs, and sheds above a size threshold. Even projects that seem minor can trigger permit requirements, so it is always best to check first.
How to apply for a building permit
Visit your local building department or their website. Most jurisdictions accept online applications. You will typically need a site plan, project description, and may need contractor information. Processing times vary from same-day for simple projects to several weeks for larger builds.
Common permit violations to avoid
Building without a permit, exceeding approved dimensions, and ignoring setback requirements are the most common violations. Penalties can include fines, required removal of the structure, and complications when selling your home.
