San Jose's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In San Jose, California, there are 7 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.

Weed Ordinances

San Jose's City Council can declare weeds or refuse growing on any street, parkway, sidewalk, or private property a public nuisance, then have the fire chief abate it and bill the property owner for the cost.

Key details: Declared by: City Council resolution. Notice period: Posted 6 days before hearing. Owner remedy: Clear weeds before crew arrives. Unpaid cost: Becomes a lien on property. Governing chapter: SJMC Chapter 9.12.

Ignoring a posted nuisance notice lets the fire chief or a hired contractor clear the property and bill the owner directly; unpaid abatement costs are recorded as a special assessment lien against the parcel.

Rainwater Harvesting

San Jose allows rain barrels or cisterns as a Building Official-approved alternative when a single-family home can't meet the standard downspout-to-landscaping drainage rule.

Key details: Who decides infeasibility: Building Official. Allowed alternative: Rain barrels or cisterns. Default rule: Downspouts to landscaped areas. Standard referenced: SF Bay MRP NPDES permit. Applies to: Single-family homes, no permit.

Failing to meet the downspout-disconnection requirement (or an approved alternative like rainwater harvesting) where infeasibility hasn't been found by the Building Official constitutes property blight under Chapter 17.72, enforceable through administrative citation or abatement.

The rules around rainwater harvesting in San Jose lean permissive, but that does not mean anything goes.

Native Plants

During a declared 30%+ water shortage, San Jose bans new outdoor landscape installation with overhead irrigation May through October, but drought-tolerant and native plants are exempt from that ban.

Key details: Trigger: 30%+ water shortage resolution. Restricted window: May through October. Exempt: Drought-tolerant or native plants. Also exempt: Food-producing plants or trees. Code section: SJMC § 15.10.360.

Installing new landscaping with an active overhead sprinkler system during May-October of a declared 30%+ shortage, without disconnecting, removing, or converting it to drip irrigation and without qualifying for the drought-tolerant/native-plant exception, violates § 15.10.360 and is enforced under the city's water shortage response chapter.

San Jose is more permissive than most cities when it comes to native plants. That said, there are still limits.

Tree Removal & Heritage Trees

San Jose bans removing any live or dead tree 38+ inches in trunk circumference from private property without a tree removal permit or development permit under Chapter 13.32 of the Municipal Code.

Key details: Tree threshold: 38" circumference at 54" height. Permit needed: before removing any live or dead tree. Enforcing office: Director, Planning, Building & Code Enforcement. Penalty: administrative fine set by council resolution. Replacement: on-site or city-approved replacement tree required.

Unlawful removal without a permit is enforced through an administrative citation and a fine set by city council resolution under § 13.32.060; heritage tree vandalism, mutilation, or destruction carries its own resolution-set civil penalty per tree under § 13.32.140.

This is one of the stricter rules in San Jose's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Water Restrictions

San Jose bans irrigating outdoor landscaping with potable water between 10 a.m. and 8 p.m., and caps landscape-irrigation-system watering at fifteen minutes per station per day, under Municipal Code § 15.10.290: hand watering, drip irrigation and self-closing hoses are exempt.

Key details: Time-of-day ban: No irrigation 10 a.m.–8 p.m.. Duration cap: 15 minutes per station per day. Exempt methods: Drip irrigation, self-closing hose, hand watering. Governing section: SJMC § 15.10.290. Drought escalation: Council may add day-per-week limits.

San Jose's code carries no dedicated penalty for Chapter 15.10; violations default to Municipal Code § 1.08.010 as a misdemeanor, up to $1,000 and six months' jail, with each day of continued violation a separate offense.

Composting

California SB-1383 requires every San Jose resident and business to separate food scraps and yard trimmings from trash. San Jose's Sustainable Materials Management program provides curbside organics carts and enforces participation through franchise haulers and the city.

Key details: State law: California SB-1383. Effective date: January 1, 2022. Diversion target: 75% organics by 2025. Curbside hauler: GreenWaste and California Waste. Edible-food rule: Tier 1 and Tier 2 donation.

Generators that fail to separate organics after notice and education face administrative fines starting at $50–$100 per violation and rising to $500 for repeat or large-generator offenses, with potential CalRecycle penalties to the city itself.

Tree Trimming

San Jose requires street trees to keep an 8-foot vertical clearance over sidewalks and 14-foot clearance over the roadway, and bars pruning or removing a street tree without a permit from the Parks, Recreation and Neighborhood Services director.

Key details: Pedestrian clearance: 8 feet minimum over sidewalk. Vehicular clearance: 14 feet minimum over pavement. Permit required: To prune, remove, or work near roots. Enforcing agency: Parks, Recreation and Neighborhood Services director. Owner liability: Liable for injuries from unmaintained trees.

Pruning, removing, or doing root-zone work on a street tree without a director-issued permit is unlawful; failing to maintain required clearance can trigger a violation notice, city-billed corrective work, and liability for resulting injuries.

The Bottom Line

Compared to many U.S. cities, San Jose gives residents more room on landscaping rules. 2 of the 7 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

These rules come from San Jose's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
