How Vacaville Handles Landscaping Rules: A Practical Guide

Vacaville maintains 145 local ordinances across all categories, and 8 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Vacaville falls on the strict-to-permissive spectrum compared to other cities.

Rainwater Harvesting

Vacaville encourages, but does not mandate, rain gardens, cisterns, and catchment systems in landscape design under City Code Section 14.27.030.150, while requiring project applicants to design for on-site infiltration of the one-inch, 24-hour storm event.

Key details: Governing section: VMC § 14.27.030.150. Mandatory infiltration design: One-inch, 24-hr storm or 85th percentile event. Rain harvesting status: One of several encouraged/required-choice options. Cross-referenced soil rule: VMC § 14.27.030.060.A.3 (friable soil). Additional reviewer: Regional Water Quality Control Board (per subsection B).

Chapter 14.27 violations, including a landscape documentation package that fails to show the required infiltration capacity under subsection D, are enforced through Section 14.27.030.030's reference to Vacaville Municipal Code Chapter 1.16 general penalties and any other legal remedy. Because rain gardens and cisterns are one option among several listed in subsection E rather than a mandatory single technique, a project can satisfy the section without installing a cistern as long as it meets the infiltration-capacity standard some other listed way.

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

Tree Removal & Heritage Trees

Cutting down, removing, or destroying any tree six inches or more in diameter at breast height, on private or public property in Vacaville, requires a tree removal permit under VMC Section 14.09.250.060(B)-(C). The Director of Community Development issues the permit after a site visit weighing the tree's health, species, size, and visibility, and unauthorized removal is a misdemeanor.

Key details: Protected size: 6+ inches diameter at breast height. Permit issuer: Director of Community Development. Exempt: Fruit/nut trees, nursery stock, hazards, utility pruning. Replacement ratio: Up to 8:1 for large native trees. Monitoring: 5 years, 80% survival required.

Unauthorized tree removal is a misdemeanor under VMC Section 14.09.250.060(K), enforced through Chapter 1.16, General Penalty, with each day of a continuing violation charged as a separate offense. Beyond the criminal penalty, the Director of Community Development can independently require the violator to replace the removed tree or trees, or to pay the City the cost of replacement, and that remedy stacks on top of, rather than instead of, the misdemeanor charge. Determinations can be appealed under Chapter 14.09.030, Common Procedures.

Compared to other cities, Vacaville takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Artificial Turf

Vacaville's Public Nuisance chapter defines artificial turf as an accepted form of landscaping. Under Municipal Code Section 8.10.020, "artificial turf/sod designed specifically for exterior landscaping" counts alongside grass, ground covers, and decorative rock as qualifying landscaping material, while gravel, decomposed granite, and indoor-outdoor carpet do not.

Key details: Artificial turf status: Expressly permitted landscaping material. Also permitted: Grass, shrubs, decorative rock/bark. Excluded materials: Gravel, decomposed granite, carpet. Governing definition: VMC § 8.10.020. Enforcement risk: Nuisance citation for non-conforming surface.

A yard covered in a prohibited surface, gravel, broken concrete, decomposed granite, or indoor-outdoor carpet dressed up as landscaping, doesn't meet the Section 8.10.020 definition, so code enforcement can cite it as a nuisance condition under Section 8.10.060(C) for detracting from neighboring property values, triggering the same notice-to-abate and fine schedule as any other nuisance, up to $500 for a third infraction within 12 months.

If you are coming from a city with tighter rules, you will find Vacaville gives residents more flexibility on artificial turf.

Water Restrictions

Vacaville Municipal Code Chapter 13.20 (Water Conservation) prohibits runoff, overspray, and using potable water to wash hardscape without a shutoff nozzle. Violations carry fines up to $500. The City also enforces a Water Efficient Landscape Ordinance (WELO) at VMC Section 14.27 implementing California's Model Water Efficient Landscape Ordinance under California Code of Regulations Title 23 Section 490 et seq.

Key details: Primary Code: VMC Ch. 13.20. Max Fine: Up to $500 per violation. WELO: VMC Sec. 14.27. State Rule: Cal. Code Regs. Tit. 23 Sec. 490+. Trigger Threshold: 500 sq ft new / 2,500 sq ft rehab.

Violations of VMC Chapter 13.20 (runoff, overspray, hosing hardscape, non-shutoff nozzle) carry fines up to $500 per occurrence. Failure to comply with the Vacaville WELO blocks landscape final on new construction or remodel permits. State Water Board violations of emergency conservation rules add civil penalties on top of city fines.

Composting

Vacaville residents and businesses must subscribe to Recology Vacaville Solano's organics (green-cart) curbside service under California SB 1383 (Public Resources Code Sections 42649.8-42649.97). Food scraps, food-soiled paper, and yard trimmings go to Jepson Prairie Organics on Hay Road for composting. Backyard composting is allowed as a complement, subject to standard nuisance and rodent-control rules.

Key details: State Law: Cal. SB 1383 (PRC 42649.8+). City Hauler: Recology Vacaville Solano. Compost Site: Jepson Prairie Organics (Hay Rd). Bin Color: Green = organics. Backyard Compost: Allowed (no nuisance).

Failing to subscribe to or participate in SB 1383 organics collection is a CalRecycle-enforceable violation; jurisdictions face state-level penalties and pass enforcement through Recology service rules and city code. Contamination of the green cart with non-organic material can result in tag-and-leave service, contamination fees, or downgrade to standard refuse handling. Backyard piles that create odor or rodent nuisances can be abated under VMC 6.20 or 8.04.

Weed Ordinances

Vacaville Municipal Code Chapter 8.04 (Abatement of Weeds and Rubbish) declares dry vegetation, weeds, and rubbish a public nuisance, with annual June 1 inspections by Code Enforcement and lien recovery for non-abated parcels. The Solano County Agricultural Commissioner's Weed Management Area (WMA) handles state-listed noxious weeds (yellow starthistle, perennial pepperweed, medusahead) under California Food & Ag Code Sections 5001-5026.

Key details: Local Code: VMC Ch. 8.04. Inspection Date: On or about June 1. Lien Authority: Cal. Gov. Code Sec. 39561+. Noxious Weed Program: Solano WMA. Noxious Weed Statute: Cal. FAC Sec. 5001-5026.

Failure to abate after written notice authorizes Vacaville to enter the property, clear the weeds, and bill the owner under VMC 8.04 - costs become an administrative fine plus a tax-roll lien. State-listed noxious-weed violations can result in Agricultural Commissioner abatement under California Food & Ag Code Sections 5021-5026 with cost recovery. PRC 4291 defensible-space violations carry separate Cal Fire administrative penalties.

Native Plants

Vacaville does not require native plants in standard residential yards, but the City's Water Efficient Landscape Ordinance at VMC Section 14.27 strongly favors low-water and California-native species through plant-factor calculations under the WUCOLS classification. Solano County Water Agency lawn-conversion rebates require at least 50% drought-tolerant or California-native plants at maturity.

Key details: WELO Citation: VMC Sec. 14.27. State Rule: Cal. MWELO (CCR Tit. 23 Sec. 490+). Plant Factor Source: WUCOLS IV. Rebate Threshold: >=50% low-water/native at maturity. Rebate Administrator: Solano County Water Agency.

Failing the WELO water-budget calculation on a covered project under VMC 14.27 blocks landscape final on the building permit. There is no penalty for choosing non-native plants in a standard residential yard outside the WELO trigger, but homeowners forfeit eligibility for SCWA conversion rebates if planting fewer than 50% qualifying low-water/native species.

Tree Trimming

Vacaville Municipal Code Section 14.09.250.060 protects all trees with a diameter at breast height of six inches or more. Significant pruning that risks destroying the tree requires authorization from the Director of Community Development. Routine maintenance trimming is allowed, but cuts that exceed standard arboricultural practice can trigger a Tree Removal Permit requirement and replacement-tree mitigation.

Key details: Protected Size: >=6 in DBH. Primary Code: VMC Sec. 14.09.250.060. Maintenance OK: ANSI A300 routine prune. Permit Trigger: >25% canopy / topping. Street Trees: Public Works coordination.

Severe pruning or topping of a protected tree (DBH 6 inches or more) without authorization is treated as removal and subjects the owner to enforcement under VMC 14.09.250.060, including replacement-tree requirements, restoration orders, and administrative citation. Public-tree damage is separately enforceable through Public Works.

The Bottom Line

Compared to many U.S. cities, Vacaville gives residents more room on landscaping rules. 2 of the 8 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.

Keep in mind that Vacaville 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.
