Saratoga HOA Guide: Local Rules for Boards and Owners

Saratoga is one of 14 Santa Clara County communities identified as at risk for wildfire, according to the city. Under state law the higher-risk parts of the city make up its wildland urban interface, or WUI. The city says WUI properties face special requirements, including brush abatement, defensible space and a disclosure to buyers that the property is in a very high fire hazard severity zone.

The state’s fire agency, CAL FIRE, released updated fire hazard severity zone maps for locally protected areas on February 24, 2025, in three classes: moderate, high and very high. Each local agency then had to adopt them. In the half of the city it covers, the Saratoga Fire Protection District went a step further. Its Ordinance No. 2-2025 adopts the zones CAL FIRE recommended and also designates additional territory as a moderate zone, extending that zone to Saratoga-Sunnyvale Road and Saratoga-Los Gatos Road. The district’s map is dated May 20, 2025 and is posted on its website. The city publishes its own fire hazard zone map and a WUI map. Look up every address in your community, common-area parcels included, rather than assuming.

What the zone means in practice, according to the County Fire Department:

• Homes in a high or very high zone must maintain defensible space all year. Affected owners get a letter each spring saying whether they need 30 feet or 100 feet.
• Each January owners are reminded to clear native brush around their homes. Fire crews start inspecting hillside properties in early April.
• A property that does not meet the vegetation clearance rules gets a notice of violation. If it is still out of compliance at about the end of June, a contractor may do the work and the cost goes on the parcel’s property tax bill.
• Anyone selling a home in the WUI must obtain an inspection verifying that it complies with the applicable fire codes.
• Building in the city’s WUI and high fire hazard areas must meet the WUI Code in Article 16-52 of the city code, with review by the County Fire Department.

Common area is where this lands on the board. If the association owns slopes, open space or the land between homes and a hillside, the association is the owner that gets the letter. The city also asks owners in fire-prone areas to keep defensible space along the roads and driveways used for evacuation, which matters if your streets are private.

There is free help. The County Fire Department offers hillside residents a free WUI preparedness inspection on request at (408) 378-4010. The fire district and the Santa Clara County FireSafe Council offer individual homeowners a free 60-minute home ignition zone assessment with written recommendations, and the FireSafe Council runs free chipping for residents who clear their own defensible space. The district’s website also explains how a neighborhood becomes a Firewise community. Whether to organize one is a choice for your community, not a legal requirement.

Saratoga has two separate vegetation programs, run by two different agencies, and a hillside parcel may hear from both. The Weed Abatement Program is managed by the Santa Clara County Department of Agriculture. The Brush Abatement Program, also called the WUI preparedness inspection, is managed by the County Fire Department and is described in the section above.

For weed abatement, the county’s inspection deadline for Saratoga parcels is April 30. Every parcel in the program must then keep meeting the county’s minimum fire safety standards until October 31. The county charges an inspection fee each year to every parcel in the program and bills much more if its contractor has to do the work. A parcel leaves the program after three consecutive years of compliance. The city’s and the county’s websites showed different fee figures when we checked, so ask the county for the current amount at (408) 282-3145.

Associations that own vacant lots, slopes or open space should have the mowing or clearing done before the end of April and keep it up through the fall, not just on inspection day.

Saratoga does not license short-term rentals. The city’s short-term rental page says its municipal code prohibits renting a single-family home, or rooms within the home, for 30 consecutive calendar days or less. It cites City Code sections 15-06.360 and 5-25.020(f), and it gives the reason as limiting traffic, noise and guest turnover on quiet residential streets.

The city investigates complaints case by case. A formal complaint requires the city’s complaint form, and anonymous complaints are not accepted. Code Enforcement is at 408-868-1214. For a board that means someone, usually a neighbor or a board member, has to put a name on the complaint.

The city’s page speaks of single-family homes and rooms within them. If your community is condominiums or townhomes, ask Code Enforcement how the city applies the rule to your units, and do not rely on the city alone. Your own documents are a separate tool. California Civil Code section 4741 limits how far an association can restrict rentals generally, but it does not stop an association from prohibiting rentals of 30 days or less.

Saratoga protects trees by size, and the size is small. The city measures the trunk four and a half feet above the ground:

• Any tree of any species with a trunk diameter of 10 inches or more (31 inches around) is protected.
• Ten native species are protected from 6 inches in diameter (19 inches around): big leaf maple, black oak, blue oak, California buckeye, coast live oak, coast redwood, Douglas fir, scrub oak, tan oak and valley oak.

A city permit is required before removing a protected tree. A permit is also required for pruning that does not follow International Society of Arboriculture pruning guidelines, so severe pruning of a common-area tree can need a permit even though the tree stays. Before any construction under protected trees, the city requires a tree preservation plan.

The rules reach projects near a tree as well. The city’s planners say arborist review is required for work within five feet of a protected tree’s canopy dripline, and paving within five feet of the dripline needs a tree encroachment permit from the City Arborist. Keep that in mind before the board approves new paths, patios, retaining walls or repaving. An approval from your architectural committee does not replace the city permit, and an owner’s city permit does not replace your approval.

Fire safety and tree protection can pull in opposite directions on a hillside. If a fire inspector asks for clearance that involves a protected tree, ask the City Arborist through the Planning counter at 408-868-1222 how to handle it before your vendor cuts.

Saratoga’s noise rules are in Article 7-30 of the city code, and they are specific enough to write straight into a landscape contract:

The city’s noise page lists the restricted schedule for gas leaf blowers, while its leaf blower sheet gives the same hours for blowers without that qualifier. The safe course is to keep all blower work inside those hours.

The leaf blower rule is aimed at the property owner. The city’s information sheet says the owner must make sure the rule is followed on the property no matter who is running the blower. After a verified violation the city sends a courtesy notice to the owner, the landscape company or both, and further verified violations at the same place can bring the owner a citation. For common area, the owner is the association. Ask your landscaper to show the maker’s label on each blower. The city says many compliant models carry an ANSI B175.2 sticker.

Construction hour violations are cited by the Sheriff’s Office. Noise complaints go to Code Enforcement at 408-868-1214 on weekdays, and to Sheriff’s dispatch at 408-299-2311 after hours, on weekends and on holidays. Your own rules can set shorter hours.

Saratoga treats its geology as a planning matter. A geotechnical clearance is required for any new building or structure, or an addition to one, in an area with geologic or geotechnical hazards or constraints. The city gives its hillsides, with landslide potential, and land close to creeks, with liquefaction potential, as examples. Every proposed basement needs one too.

The review is done by the city’s geotechnical consultant at the applicant’s cost. When we checked, the city listed a flat fee of $850 for engineering staff work plus a review deposit of $5,000 for the first lot and $500 for each additional lot, with the consultant’s actual cost and a 25% surcharge drawn from the deposit. A board planning a clubhouse addition, a new retaining structure or slope repair in a hazard area should price that in and allow time for it.

Other points from the city’s planning pages that come up in hillside communities:

• Slope cuts into what can be built. On lots with an average slope over 10%, the net site area used to work out allowable floor area is reduced, and some easements reduce it as well.
• Retaining walls in a front or exterior side setback are limited to three feet in height. Other retaining walls are limited to seven feet.
• Parallel retaining walls need at least five feet between them, and where walls are within 30 feet of each other their combined height is capped at 20 feet.
• Fences and gates fall under the city’s fence rules, with heights that depend on location and zone. Exterior changes, fences and paving go to Planning. Driveway encroachment permits go to Public Works.
• New landscaping of more than 500 square feet, or replacing 2,500 square feet or more, needs a permit under the city’s water-efficient landscape rules.

That last item is easy to miss. A common-area relandscaping project can cross the 2,500 square foot line quickly, so ask Planning before the contractor starts.

The city does not run a water utility. San Jose Water, a regulated private utility, lists Saratoga in its service area, and it buys water from Valley Water, the county’s wholesale water agency. So watering rules here come from the water company’s tariff and from the state, not from a city ordinance.

San Jose Water’s Rule 14.1 is its water shortage plan, and it works in stages. The first stage is a call for conservation, and it lists these as wasteful uses:

• Running an unattended irrigation system for more than 15 minutes per station per day, or at any time between 10 a.m. and 8 p.m. Drip zones and low-flow sprinklers are exempt from those limits.
• Any watering that causes runoff, and watering during measurable rain or for up to 48 hours after it.
• Leaving broken sprinklers or leaks unrepaired more than five business days after written notice.
• Washing vehicles, buildings or pavement with a hose that has no shut-off nozzle, and running a fountain that does not recirculate.

Later stages limit watering to three, two and then one day a week by street address. Irrigation with recycled water is exempt. Ask San Jose Water at 408-279-7900 which stage is in effect and how it applies to a common-area meter, and give the answer to your landscape contractor in writing.

Two points matter for the budget. First, Valley Water’s Landscape Rebate Program pays a base rate of $2 per square foot to convert high-water-use lawn, and $1 per square foot for its lawn-to-mulch option on commercial, institutional and multifamily properties of five or more units. The cap for commercial sites and multifamily sites of five or more units is $100,000, against $3,000 for a single home, and Valley Water says funding lasts until June 30, 2027 or until it runs out. You must apply, pass a pre-inspection and receive a written Notice to Proceed before any work starts. Ask Valley Water which category your common-area account falls in. Second, a state law passed in 2023 (AB 1572) will bar the use of drinking water on nonfunctional turf in HOA common areas starting January 1, 2029. A board with decorative lawn can use the rebates to pay for part of a conversion it will have to make anyway.

On owners’ lots, Civil Code section 4735 prevents an association from banning low-water plants or artificial turf as a replacement for lawn.

The city’s ADU page covers its A, R-1 and HR zoning districts. An ADU may not exceed 1,200 square feet, and a junior ADU is a unit of up to 500 square feet inside an existing single-family home. Permits are handled over the counter by the Building Division without a public hearing. The city’s planners say an ADU generally must meet the front setback and sit at least four feet from side and rear property lines.

Design review comes first in some cases, including a new multi-story structure, a structure over 18 feet tall and a site in certain zones of the city’s Ground Movement Potential Map. The city also offers a bonus of 10% in floor area and lot coverage, with planning and building fees waived, for an ADU that is deed-restricted to lower-income occupancy on a lot of at least 10,000 square feet.

For boards, the state rule matters more than the city one. Civil Code section 4751 voids provisions in CC&Rs that prohibit or unreasonably restrict an ADU or junior ADU on a lot zoned for single-family use. An association can still apply reasonable restrictions through its architectural review process.

Saratoga’s police service is the Sheriff. The Santa Clara County Sheriff’s Office West Valley Patrol Division provides law enforcement under contract with the city, and its traffic officers enforce traffic laws here. The non-emergency number is 408-299-2311. Residents can also ask the Sheriff’s Office for a patrol check while they are away.

Parking concerns on public streets, along with speeding, crosswalks and bike lanes, can be brought to the city’s Traffic Safety Commission, a panel of residents that reviews them. We could not open the parking sections of the city code when we checked, so we do not quote a time limit for street parking or a rule for oversized vehicles here. Ask the Sheriff’s West Valley office at (408) 868-6600.

If your association owns its streets, parking is governed mainly by your own rules and by state towing law. Ask the Sheriff’s Office what it will and will not enforce inside your community before you write a parking rule that depends on it.

Sewers in Saratoga belong to two special districts, not the city. The West Valley Sanitation District serves a portion of Saratoga, according to the county’s Local Agency Formation Commission, and the Cupertino Sanitary District says it serves portions of Saratoga as well. Find out which one serves your streets before there is a backup. Both list the same after-hours emergency number, (408) 299-2507.

The West Valley Sanitation District’s website describes a Private Lateral Replacement Program: an interest-free five-year loan of up to $3,500 to replace a failing or failed sewer line serving a home. Whether a given pipe in your community is the owner’s, the association’s or the district’s depends on your governing documents and the district’s rules, so ask the district before you assign a repair bill.

Trash and recycling service comes from West Valley Recycles, which serves Campbell, Los Gatos, Monte Sereno and Saratoga. It handles service changes, billing and bulky-item cleanups at (408) 283-9250.
