How Fairfield Handles Landscaping Rules: A Practical Guide

Fairfield maintains 100 local ordinances across all categories, and 7 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Fairfield falls on the strict-to-permissive spectrum compared to other cities.

Tree Trimming

Fairfield Municipal Code Chapter 21 (Trees and Shrubs) prohibits anyone other than the property owner or city-authorized personnel from pruning, injuring, or destroying any tree on private or public land. Protected trees under Section 25.36 require a permit before significant pruning.

Key details: Chapter: FMC Chapter 21 Trees and Shrubs. Protected-tree code: FMC Section 25.36 Tree Conservation. Protected size: 6 inches caliper at breast height (4.5 ft). Heavy pruning: Treated as removal; permit required. Unauthorized removal mitigation: 3 inches replanted per inch removed.

Unauthorized injury or pruning of a street tree, park tree, or protected tree can lead to administrative penalties and replacement requirements at the 3:1 mitigation ratio. Civil cost recovery for damage to public trees is also available to the city.

Water Restrictions

Fairfield permanently prohibits landscape irrigation between noon and 6:00 p.m., aligns with statewide bans on watering non-functional turf at commercial sites (AB 1572), and tightens restrictions when Lake Berryessa drops to 50% or 37% full.

Key details: No-watering window: Daily noon to 6:00 p.m.. Non-functional turf: Prohibited at CII sites (AB 1572). Stage 2 trigger: Lake Berryessa at 50% full. Outdoor moratorium trigger: Lake Berryessa at 37% full. Fine schedule: Warning, $25, $50, $100.

First offense: written warning. Second: $25. Third: $50. Fourth and beyond: $100 per violation. Continued non-compliance can lead to flow restrictors or service termination under standard utility rules.

Weed Ordinances

Fairfield enforces weed and vegetation abatement under Chapter 27 (Community Preservation) using California Government Code authority. Notices issue in spring before fire season, and uncorrected properties are abated by city contractor with costs liened against the parcel.

Key details: Primary code: FMC Chapter 27 + Cal. Gov. Code Section 39501+. Annual cycle: Spring notices, pre-fire-season deadline. Defensible space: PRC Section 4291 (30+ ft from structures). Hearing right: Yes, before formal nuisance abatement. Cost recovery: Special assessment / property tax lien.

First step is a written notice. Continued non-compliance triggers administrative citations with escalating fines, city-contracted abatement, and a special-assessment lien. Repeat offenders may face misdemeanor prosecution and increased fines.

Grass Height Limits

Fairfield Municipal Code Chapter 27 (Community Preservation) requires properties to be maintained free of weeds, trash, and overgrown vegetation that constitutes a fire hazard. Overgrown grass and weeds are abated administratively, with costs becoming a special assessment on the property.

Key details: Code section: FMC Chapter 27 Community Preservation. Numeric height limit: Not specified; fire-hazard standard applies. Vacant lots: Must be maintained to avoid unreasonable fire risk. Abatement cost recovery: Special assessment on property. Code Compliance phone: (707) 428-7587.

First contact is typically a courtesy notice. Failure to abate leads to administrative citations with escalating fines, city-contracted clean-up at the owner's expense, and a special assessment lien on the property. Repeat or fire-season violations can be charged as misdemeanors.

Native Plants

Fairfield encourages native and drought-tolerant plants and complies with California's Model Water Efficient Landscape Ordinance (MWELO) for new and renovated landscapes that meet the state thresholds. There is no city ban on lawns for existing residential properties.

Key details: State framework: California MWELO (23 CCR Section 490+). New-landscape threshold: 500 sq ft permitted projects. Rehab threshold: 2,500 sq ft permitted projects. Future non-functional turf ban: AB 1572 (CII properties, phased). Incentives: Turf-replacement rebates via Water Division.

MWELO non-compliance is handled through the project plan-check process - landscape plans that do not meet MWELO are not approved. Existing residential lawns face no penalty for being installed, but water-use must still respect the noon-to-6 p.m. ban and any drought-stage restrictions.

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

Tree Removal & Heritage Trees

Fairfield's Section 25.36 Tree Conservation ordinance requires a permit to remove any protected tree. Unauthorized removal triggers mitigation at three inches replanted for every inch removed.

Key details: Code: FMC Section 25.36 Tree Conservation. Protected threshold: 6 inches caliper at breast height (4.5 ft). Authorized-removal replacement: 1 inch per inch removed. Unauthorized-removal penalty: 3 inches per inch removed. Public trees: Public Works approval under Chapter 21.

Unauthorized removal of a protected tree results in mandatory replacement at 3 inches per inch removed, administrative citations, and potential restitution. Damage to public trees may also be recovered as civil cost-of-replacement by the city.

This is not one of those rules that cities tend to ignore. Fairfield actively enforces its tree removal & heritage trees requirements.

Composting

Under California SB 1383, all Fairfield residents and businesses must subscribe to organic-waste collection and separate food scraps, food-soiled paper, and yard waste from the trash. Backyard composting remains permitted and counts as compliance for residents.

Key details: Authority: California SB 1383. Resident requirement: Subscribe + separate organics from trash. Business start date: January 1, 2022. Resident enforcement start: January 1, 2024. Cure period after notice: 60 days.

Following a notice and the 60-day cure period, repeated contamination or non-participation can result in administrative fines escalating per the city's enforcement schedule. The hauler may also bill for contamination-removal fees.

The Bottom Line

Fairfield's landscaping rules 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 Fairfield is broadly strict or permissive.

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