How Lincoln Handles Landscaping Rules: A Practical Guide

Lincoln maintains 100 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 Lincoln falls on the strict-to-permissive spectrum compared to other cities.

Rainwater Harvesting

Capturing rainwater from rooftops for non-potable landscape use is legal in Lincoln without a water-rights permit under the California Rainwater Capture Act (Water Code 10574). Larger cisterns and any plumbing tie-in must comply with the California Plumbing Code adopted in Lincoln Municipal Code Title 15.

Key details: Rainwater capture legal: Yes (Cal. Water Code 10574). Water-rights permit required: No. Building permit threshold: 5,000 gal or plumbed tie-in. Cross-connection rules: 17 CCR 7583+. Adopted plumbing code: 2022 CPC via LMC Title 15.

Plumbing without required permits is a violation of Title 15 (Buildings and Construction) and subject to building-code stop-work orders and administrative citations. Cross-connection of rain-fed systems with potable supply violates LMC Chapter 13.04 and Title 17 California Code of Regulations 7583 et seq. (cross-connection control).

If you are coming from a city with tighter rules, you will find Lincoln gives residents more flexibility on rainwater harvesting.

Native Plants

Lincoln residents have a state-law right to install drought-tolerant and California native landscapes; HOAs and the city cannot prohibit them under Civil Code 4735, and any new landscape over 500 sq ft must meet the state Model Water Efficient Landscape Ordinance (MWELO).

Key details: HOA cannot ban natives: Cal. Civ. Code 4735. MWELO threshold (permit): 500 sq ft. MWELO threshold (no permit): 2,500 sq ft. Turf cap: Per MWELO water budget. Rebates available: Yes via PCWA.

Civil Code 4735 violations by HOAs are enforced through civil action by the homeowner; HOAs that ignore the rule may owe attorney's fees. Failure to comply with MWELO on permitted projects is enforced by Community Development as a planning/building violation; the city may withhold final inspection until the landscape plan is corrected.

The rules around native plants in Lincoln lean permissive, but that does not mean anything goes.

Grass Height Limits

Lincoln treats overgrown weeds, dry grass and rank vegetation as a public nuisance subject to abatement under the city's Health and Safety title and the California Government Code weed abatement procedure (Gov. Code 39501 et seq.) administered locally each spring.

Key details: Fixed height limit: Not stated in code. Enforcement basis: Title 8 nuisance + Gov. Code 39501. Abatement: City may cut and lien property. Fire-season focus: Yes.

Code enforcement issues a courtesy notice first. If not corrected within the cure period (typically 10-30 days under Gov. Code 39574), the city may abate (cut/clear) and bill the owner; unpaid charges become a special assessment lien on the property tax roll. Repeat or fire-season violations can be cited as administrative citations under the city's general penalty provisions.

Water Restrictions

Lincoln Municipal Code prohibits watering lawns or gardens from an open hose without a shut-off nozzle (LMC 13.04.420), bars unreasonable water runoff onto gutters or pavement (LMC 13.04.440), and authorizes the city to limit irrigation hours during shortages (LMC 13.04.430).

Key details: Shut-off nozzle required: Yes (LMC 13.04.420). Runoff prohibited: Yes (LMC 13.04.440). Leaks prohibited: Yes (LMC 13.04.410). City may limit hours in shortage: Yes (LMC 13.04.430). MWELO threshold: 500+ sq ft new landscape (state).

Violations of Chapter 13.04 are misdemeanors under the city's general penalty provisions and may also be cited as administrative water-waste citations. The Water Shortage Contingency Plan typically escalates from a written warning to flow restriction or service termination for repeated waste during declared shortage stages.

Tree Trimming

Trees in the public right-of-way and in city parks are maintained by the City of Lincoln Public Services Department; private property owners must keep their trees pruned back from sidewalks, streets and traffic signs as a nuisance under Title 8 and Title 12 of the Lincoln Municipal Code.

Key details: Heritage-tree ordinance: No citywide ordinance found. Sidewalk clearance: 8 ft typical. Street clearance: 14 ft typical. Street trees: Public Services maintained. HOA review: Often required in Lincoln Hills/master-planned areas.

If overhanging or dead branches create a hazard, the city may issue a written notice requiring trimming within a set period. Failure to comply allows the city to abate (trim or remove) and bill the property owner, similar to weed abatement under Gov. Code 39501 et seq. Unauthorized removal of a city-owned street tree can lead to civil restitution for the appraised tree value.

Artificial Turf

Artificial turf is a permitted landscaping material in Lincoln. California Civil Code 4735 expressly bars HOAs from prohibiting artificial turf in single-family yards, and the city has no overlay ordinance restricting it.

Key details: City ban?: No. HOA ban allowed?: No (Cal. Civ. Code 4735). Permit required?: Generally no for like-for-like replacement. MWELO treatment: Counted as low water use area. Setback compliance: Must meet Title 18 zoning.

HOA enforcement against compliant artificial turf installations is barred by Civil Code 4735; homeowners may sue and recover attorney's fees. City violations would arise only from collateral issues - missing drainage, blocked sidewalk, prohibited material near a creek - and would be cited under Title 13 stormwater or Title 18 zoning provisions with standard administrative-citation fines.

Lincoln is more permissive than most cities when it comes to artificial turf. That said, there are still limits.

Weed Ordinances

Lincoln treats dry weeds, rank vegetation and combustible undergrowth as a public nuisance subject to mandatory abatement during fire season under California Government Code 39501-39588 and Title 8 of the Lincoln Municipal Code.

Key details: Authority: Cal. Gov. Code 39501-39588. Season: Spring-fall (fire weather). Cure period: 10-30 days from notice. Unpaid abatement: Becomes tax-roll lien. PRC 4291 defensible space: 100 ft around structures.

If the owner does not abate within the cure period (commonly 10-30 days), the city contractor cuts the property and the cost - plus an administrative charge - becomes a special assessment on the property tax roll under Gov. Code 39574-39581. Failure to maintain defensible space under Public Resources Code 4291 can also trigger a $100-$500 civil penalty.

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

Tree Removal & Heritage Trees

Owners may remove most trees on private property in Lincoln; removal of street trees or protected/heritage oaks requires city approval, and replacement may be required during development.

Key details: Private Land: Owner may remove (most). Street/Oak Trees: City approval. Development: Replacement may apply. Authority: Public works / planning.

The Bottom Line

Compared to many U.S. cities, Lincoln gives residents more room on landscaping rules. 3 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.
