Contra Costa County HOA Guide

Hercules HOA Guide: Local Rules for Boards and Owners

Hercules has about 26,000 residents and a homeownership rate near 79%. Nearly the whole city was built as planned neighborhoods, and the city maintains their parks, street lights and roadside landscaping through assessment districts on the tax bill.

This guide collects the city rules a Hercules board runs into most often, and points you to the How2HOA guide that explains what to do about each one.

Local rules on this page were checked against the City of Hercules’ website and municipal code on October 10, 2026. The online code is current through March 2025, and several city pages would not open for us, so we left out anything we could not confirm. Confirm the current rule before you act on it. Sources are listed at the bottom of the page.

HOAs in Hercules at a glance

No public agency publishes a count of Hercules’ HOAs or a typical dues figure, so we do not quote one. What the public record shows is how much of each neighborhood the city maintains through its districts:

Five districtsa 2023 city report describes five landscaping and lighting assessment districts. The oldest, District 83-2, has 11 zones.
Zones by neighborhoodDistrict 83-2’s zones include Hercules by the Bay, Foxboro, the Gems and Birds, Village Parkway, the Heights, Trees and Flowers, Birds and Country Run and Citywide Parks.
Newer neighborhoodsVictoria by the Bay, Promenade, Baywood and Bayside each have a district of their own.
More homes comingthe city lists Hilltown, approved for up to 598 attached homes on 44 acres, and a 40-acre mixed-use waterfront project among its development projects.

These districts are easy to confuse with an HOA. The assessment is on the property tax bill and pays the city. Association dues pay for what your association owns.

Local rules

Rules that apply in Hercules

Three layers of rules apply to a Hercules association. State law comes first, mainly the Davis-Stirling Act. City ordinances apply to every property, whether or not it is in an HOA. Your governing documents can then be stricter than the city in most areas, and state law limits them in a few. The city does not enforce your CC&Rs, and your CC&Rs do not excuse anyone from a city rule.

Landscaping and lighting districtsThe districts pay for public landscaping, street lights, fire breaks and parks.

The city’s districts fund landscaping, street lighting, fire breaks next to open space and the upkeep of city parks, from playgrounds and fields to trails and lighting. Each district or zone pays for the work in its own area, plus a share of the landscaping and lights on the main roads.

The 2023 report found several of them running short. It projected negative balances in three zones of District 83-2 and in the Victoria by the Bay district, and pointed to irrigation, tree pruning and a 46% rise in EBMUD water rates over five years. Owners in six zones of District 83-2 approved increases between 2017 and 2022.

For a board, the question is what happens at the edge of the association’s land. If a district cuts back, the planting strips and entries next to your community may get less care, and owners will ask the board about it. Know which parcels are yours, which are the district’s and which rate your zone pays.

What to do about it: What Are HOA Assets? explains how to build a list of what your association owns, and Giving a Voice to Your HOA Community Members can help when owners ask why they pay twice for landscaping.

The Victoria by the Bay shortfallOwners turned down assessment increases twice, and the city has said services will be reduced.

The Victoria by the Bay district is the clearest example. Its 2025-26 engineer’s report covers 839 parcels and pays for neighborhood landscaping and street lights, Victoria Park and Arbor Park and a share of the main roads. The maximum assessment for a single-family home was $633.62 going into that year.

  • The report budgeted about $590,000 in revenue against about $703,000 in costs, with $230,000 of that for water.
  • It projected a negative balance of about $702,000 at the start of the year.
  • Owners rejected increases in fall 2023, by 77% to 23%, and again in spring 2024, by 70.3% to 29.7%.
  • A third proposal, adding $50 a year for 10 years, went to a hearing on June 24, 2025. The report said that without it, cost-cutting on the planting strips in front of homes would begin July 1, 2025.

The city’s page for the district says a ballot did not pass and that services will be reduced. Check that page for where things stand now.

Whatever the outcome, the lesson applies in every Hercules neighborhood. A district’s level of service is set by a vote of owners, not by the association, and the board should explain that plainly when the landscaping changes.

Parking, trailers and RVsTrailers, motor homes and boats get three hours on the street.
72-hour rule (section 3-4.1005)no vehicle may be parked on a street or alley for more than 72 consecutive hours.
Trailers, motor homes and boats (section 3-4.1018)no more than three hours on the street, apart from loading and unloading.
Heavy commercial vehicles (section 3-4.1019)vehicles with more than two axles, or 20 feet or longer, are limited to three hours, with a $500 fine.
On a lot (section 4-10.04)boats, trailers and large RVs may not be kept in a front yard. A side or rear yard is allowed behind a solid fence.

The traffic chapter says nothing about enforcement on private streets. If your association owns its streets or alleys, parking there is governed mainly by your own rules and by state towing law.

Trees and property maintenanceThe city’s tree rule is aimed at undeveloped land, and its nuisance code covers the rest.

Chapter 4-15 bars removing a mature tree, one of 12 inches or more in trunk diameter, on undeveloped or partially developed property. The chapter says the City Council does not intend to restrict tree removal by residential property owners. Trees in district-maintained strips and parks are the city’s to manage, so do not let an association vendor prune or remove them.

The nuisance chapter, 4-10, covers what Code Enforcement can act on. It includes overgrown vegetation, dead or hazardous trees and weeds, garbage cans kept in front or side yards in view of the street and unregistered or dismantled vehicles. An abatement notice gives 15 to 30 days, and unpaid city abatement costs become a lien.

Buildings of five or more units must provide recycling and organics service and remind residents about it every year.

Fire service and weedsCon Fire has served Hercules since July 1, 2025.

The Rodeo-Hercules Fire Protection District became part of Contra Costa County Fire Protection District on July 1, 2025. Some city pages still show the old district’s name. Con Fire lists Hercules among the areas its weed abatement program serves and takes complaints through an online form.

The district says its weed abatement season usually runs from May through October and that parcels must be kept up for the whole season. Cut limbs and mulch piles belong at least 30 feet from buildings. Associations that own open space or vacant lots should budget for more than one pass.

What to do about it: How to Minimize Homeowners Association Liability and our HOA maintenance and vendors section. For what the association’s insurance has to cover, see California HOA insurance requirements.

Short-term rentals and ADUsADUs may not be rented for less than 30 days.

We found no short-term rental ordinance in the Hercules Municipal Code. The city collects a 10% transient occupancy tax on stays of 30 days or less, and the ADU rules in section 13-35.320 set a 30-day minimum rental term. 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.

ADUs can be up to 850 square feet with one bedroom or 1,000 square feet with more, and junior ADUs up to 500 square feet. For boards, the state rule matters more than the city one. Civil Code section 4751 voids CC&R provisions 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.

What to do about it: How to Handle Short-Term Rentals in Your Community walks through writing and enforcing a rental rule. For ADU requests, see how architectural requests work. For the California rules, see our guide to buying, selling and renting in a California HOA. For how architectural review works under California law, see California HOA architectural review and owner rights.

Water and landscapingIrrigation water is the cost to watch.

The city’s district reports cite EBMUD water rates as a main driver of landscape costs, and the same is true for an association’s common areas. EBMUD’s lawn conversion rebate pays $1 per square foot, or $2 per square foot for projects that meet its ecological standards and are planted between September and February. The cap in any two-year period is $15,000 for commercial and large multi-family accounts and $2,000 for single-family and small multi-family accounts. EBMUD decides which class an association’s account falls in, so ask before you plan around the larger figure. The project cannot start until EBMUD approves it in writing, and artificial turf does not qualify.

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 a rebate 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.

What to do about it: put the turf conversion in your numbers with Planning Your HOA Budget and Understanding HOA Reserve Studies, then compare landscape bids with the Vendor Comparison Worksheet. For the California rules behind these projects, see California HOA maintenance and repair responsibilities and California HOA reserves.

Is this a lot for a volunteer board to track?

Quick answers

Questions Hercules board members ask

Is the landscaping district charge the same as HOA dues?

No. It is on the property tax bill and pays the city to maintain public landscaping, lights and parks in your zone. HOA dues pay for what your association owns. See What Assessments Your HOA Community Needs and Why.

Why is the landscaping in front of our neighborhood getting less care?

If the strip belongs to a city district, its budget decides. Several Hercules districts have run short, and service levels depend on what owners approve by ballot. Check the city’s district page for your zone.

How long can a boat or trailer be on the street?

Three hours, apart from loading and unloading (section 3-4.1018). Your association’s rules can be stricter on streets it owns. See How to Enforce HOA Rules in Your Homeowners Association.

Do we need a city permit to remove a tree in the common area?

The city’s mature tree chapter applies to undeveloped and partially developed property and says it is not meant to restrict residential owners. Check your own governing documents and the conditions of your original approval, and confirm with the city if the tree is in a district-maintained area.

Can our HOA ban short-term rentals?

Yes, if your governing documents say so. Civil Code section 4741 does not stop an association from prohibiting rentals of 30 days or less, though owners who bought before a restriction was adopted may have protected rights. Ask your attorney. More in How to Handle Short-Term Rentals in Your Community.

Can our HOA refuse to allow ADUs?

Not outright on single-family lots. Civil Code section 4751 voids provisions that prohibit or unreasonably restrict ADUs. The association can apply reasonable design restrictions through architectural review.

Who is our fire department?

Contra Costa County Fire Protection District, since July 1, 2025.
