Lodoga, CA

Colusa County has no local spa ordinance. Hot tubs and spas in the unincorporated area follow the California Swimming Pool Safety Act, but a spa or hot tub fitted with a listed locking safety cover can qualify for an exemption from the two-feature barrier rule.

Colusa County does not maintain a stand-alone pool ordinance for unincorporated areas. A building permit from the County Building Department is required to construct a pool or spa, and the project is reviewed for conformance with the adopted California Building Standards Codes (CBC/CRC).

Colusa County has no zoning provision singling out above-ground pools. They are treated as accessory structures for setback purposes and, where a building permit applies, must meet the same California Swimming Pool Safety Act barrier and feature requirements as in-ground pools.

Colusa County has no local pool-fence ordinance, so the unincorporated area follows California's Swimming Pool Safety Act. A new or remodeled pool/spa must have at least two approved drowning-prevention features; a qualifying enclosure must be at least 60 inches tall with self-closing, self-latching gates.

Pool safety in unincorporated Colusa County is governed by California's Swimming Pool Safety Act rather than a local ordinance. Doors with direct pool access, alarms, safety covers, and anti-entrapment drain standards are the key state-level safeguards enforced at building inspection.

Converting a garage into living space in unincorporated Colusa County changes its use. If the conversion creates a separate dwelling it is an 'accessory unit' under Section 44-4.10 of the Zoning Code; either way a building permit is required. Current California ADU law (Gov. Code 66310-66342) lets owners convert a garage to an ADU ministerially.

Unincorporated Colusa County regulates ADUs as 'accessory units' in Section 44-4.10 of the Zoning Code (Chapter 44). The county caps a unit at 1,200 sq ft (up to 2,500 sq ft on agricultural classifications) and historically required owner occupancy and a recorded deed restriction, but current California law (Gov. Code 66310-66342) preempts those owner-occupancy rules and requires ministerial approval.

In unincorporated Colusa County, a shed is an 'accessory building or structure' under the Zoning Code (Chapter 44). In the residential zones, accessory-structure setbacks are 20 feet in front, 5 feet in the rear, and 5 feet on the interior side (3 feet in the rear half of the lot); detached buildings must be 5 feet from any building.

Unincorporated Colusa County's Zoning Code defines a 'tiny home' as a structure meeting Appendix Q of the 2019 California Residential Code. A tiny home (park trailer) outside an approved mobile-home park is allowed only as an accessory dwelling unit, and only if it is on a permitted permanent foundation with wheels and tongue removed, county-approved utilities, residential exterior design, and skirting.

Unincorporated Colusa County's Zoning Code treats a carport as a 'private garage' / accessory structure. A carport must meet the residential accessory-structure setbacks - 20 feet in front, 5 feet in the rear, and 5 feet on the interior side (3 feet in the rear half of the lot) - and a detached structure must be 5 feet from any building.

Under Colusa County Zoning Code Section 44-4.90, home occupations are allowed as accessory uses to residential uses countywide, provided the use stays inside the dwelling or an accessory building, occupies limited floor space, and is conducted by resident family members only.

A home occupation in unincorporated Colusa County may display one sign under Zoning Code Section 44-4.90, regulated by the Sign Regulations in Section 44-3.50. Small signs of 8 square feet or less are allowed without a sign permit, subject to the section's standards.

Colusa County requires an administrative permit before a home occupation may operate. Zoning Code Section 44-4.90(E) states no home occupation is allowed unless an administrative permit has first been issued under the Administrative Provisions in Article 44-1.

Colusa County Zoning Code Section 44-4.120 permits cottage food operations in residential dwellings. The operation must be registered or permitted by the County Health Officer under state law, limited to one non-family employee, use no more than 25% of the dwelling, and display only a sign up to two square feet.

Under Colusa County Zoning Code Section 44-4.20, a small family day care home is treated as a residential use subject to the same standards as a residence in the same zone. Large family day care and child care centers must meet added standards and a discretionary permit, consistent with state law.

Unincorporated Colusa County sets nighttime noise limits under Chapter 13 of the County Code (Ord. No. 730). Residential property limits drop to 50 dBA from 9 p.m. to 7 a.m. (55 dBA daytime). Sound audible inside a neighbor's home is restricted, with permission presumed only between 9 a.m. and 10 p.m. Sunday-Thursday, extended to 12:30 a.m. Friday and Saturday.

Colusa County Code Section 13-8(b) allows permitted construction, alteration, repair, and maintenance noise between 7 a.m. and 7 p.m. Monday-Friday and 8 a.m. to 8 p.m. on Saturday and Sunday. Equipment must stay at or below 83 dBA at 25 feet, or 86 dBA at the property plane. Summer projects far from homes may get a 6 a.m. permit.

Colusa County's Noise Regulations (Chapter 13) have no dog-specific barking section, but Section 13-17 makes it unlawful to willfully make or continue any noise that unreasonably disturbs a neighborhood's peace and quiet, which deputies can apply to a persistently barking dog. The residential limits of Table No. 1 (50/55 dBA) also apply at the property plane.

Colusa County Code Section 13-8(b) limits powered (leaf) blowers to 70 dBA measured at 50 feet, and bars operating one blower within a 100-foot radius of another at the same time. On single-family residential property the 70 dBA limit does not apply if the blower runs less than 10 minutes per occurrence.

Outdoor amplified-sound events in unincorporated Colusa County need a Sheriff-approved registration statement under County Code Sections 13-10 to 13-16. Registration is required when an event draws more than 100 people and noise is audible at the property plane. Approved events may run sound no more than 4 hours per 24 hours and carry only music or human speech.

Colusa County Code Section 13-9 makes it unlawful to repair, rebuild, or test a motor vehicle in a residentially zoned area in a way that exceeds the residential limits of Table No. 1 (50 dBA night / 55 dBA day) at the property plane. On public roads, California Vehicle Code Sections 27150-27151 require an adequate muffler and ban modified exhausts.

Colusa County Code Section 13-6 and Table No. 1 set property-plane decibel limits by land use: residential 55 dBA day / 50 dBA night; agricultural, commercial, and industrial 60 dBA day / 55 dBA night; and 65 dBA anytime along high-noise corridors (Highway 20, I-5). Section 13-7 caps noise at 20 dBA over the limit, never above 80 dBA.

Outdoor music in unincorporated Colusa County is treated as amplified sound under County Code Sections 13-11 and 13-16. Events drawing more than 100 people with noise audible at the property plane need a Sheriff-approved registration statement. Amplified sound is capped at 4 hours per 24 hours, and exemptions end at midnight (residential) or 12:30 a.m. on weekend nights.

Industrial operations in unincorporated Colusa County fall under County Code Section 13-6 and Table No. 1, limiting agricultural, commercial, and industrial land use to 60 dBA daytime (7 a.m.-10 p.m.) and 55 dBA at night (10 p.m.-7 a.m.) at the property plane. Section 13-7 caps absolute noise at 20 dBA over the limit, never above 80 dBA.

Colusa County's Noise Regulations (Chapter 13) do not regulate aircraft or aviation noise, which is controlled by federal and California state law. California Code of Regulations Title 21, Section 5012 sets the acceptable airport noise level at a community noise equivalent level (CNEL) of 65 decibels, enforced under Public Utilities Code Section 21669.

Unincorporated Colusa County has no standalone short-term rental ordinance. Overnight lodging is handled through the Zoning Code as a recreational lodging facility, farmstay or bed-and-breakfast inn. Depending on the zone and scale, a Use Permit may be required, plus a County business license and TOT registration.

There is no STR-specific registration program, but any lodging operator must register for the County's transient occupancy tax and hold a business license. Colusa County Code Chapter 18A requires hotel operators (which includes short-term lodging) to obtain a transient occupancy registration certificate and post it on the premises.

Colusa County sets no annual cap on the number of nights a short-term rental may operate. The 30-day threshold in the transient occupancy tax defines what counts as a transient stay, but there is no limit on how many such stays a permitted lodging use may host in a year.

Unincorporated Colusa County levies a transient occupancy tax of 4% of rent on stays of 30 days or less under County Code Chapter 18A. Operators must collect TOT from guests, register, and remit it. Late payment triggers penalties of 10%, an added 10%, and up to 25% for fraud, plus interest.

There is no blanket per-guest cap for short-term rentals, but the Zoning Code limits the owner-occupied lodging types. A farmstay is capped at four guest rooms and eight guests at one time; a bed-and-breakfast inn may have up to 12 guest rooms within the primary and secondary dwellings.

Colusa County has no STR-specific parking standard. Lodging facilities must provide on-site parking per the Zoning Code's general parking standards (Section 44-3.20), and the entrance, parking area and walkways must be kept clear of obstructions and hazards. Off-street parking is part of the lodging-use review.

Colusa County has no STR-specific noise limit. Noise is controlled through general nuisance authority and zoning standards; the Zoning Code treats homes and residences as noise-sensitive receptors. Ancillary events at lodging uses (weddings, receptions) require a Use or Temporary Use Permit that can impose noise conditions.

Colusa County has no general primary-residence STR rule, but its two owner-occupied lodging paths require the owner to live on-site. Farmstays and bed-and-breakfast inns both require the property owner to reside in the primary or secondary dwelling. Non-owner-occupied whole-house rentals are not expressly authorized.

Colusa County has no separate host-presence mandate, but the owner-occupied lodging paths effectively require a resident host. Farmstays and bed-and-breakfast inns require the owner to live in the primary or secondary dwelling, and farmstays involve the host familiarizing guests with farm activities.

Colusa County's Zoning Code and transient occupancy tax chapter do not impose a short-term-rental insurance or liability-coverage mandate. Instead, lodging uses must meet health, water, sewage and building-code standards. Hosts should carry appropriate coverage voluntarily and confirm any condition in a Use Permit.

Unlike many wildfire-prone California counties, unincorporated Colusa County ALLOWS state-approved 'safe and sane' fireworks. County Code Chapter 7 (Fire Prevention) permits sale only from temporary stands run by qualified local nonprofits with a fire district permit. Sales run noon June 28 through midnight July 5, and discharge is legal only during that window. 'Dangerous' fireworks remain banned statewide.

Outdoor fire pits and recreational fires in unincorporated Colusa County are treated as open burning. Because much of the county is State Responsibility Area protected by CAL FIRE's Sonoma-Lake-Napa Unit, a CAL FIRE burn permit and a permissive 'burn day' from the Colusa County Air Pollution Control District are generally required, and burning is suspended during dry season.

Open burning of vegetation and residential waste in unincorporated Colusa County is regulated by the Colusa County Air Pollution Control District and, in State Responsibility Areas, by CAL FIRE. Burning is only allowed on permissive 'burn days,' a permit is required, and District Rule 300 prohibits burning petroleum products, tires, garbage, demolition debris and other harmful materials.

Unincorporated Colusa County has its own weed-abatement ordinance (County Code Chapter 7A) requiring property owners to clear weeds within 50 feet of structures by an annual 'plow down date.' In State Responsibility Areas, California's PRC 4291 separately requires 100 feet of defensible space. Failure to abate is an infraction and the county can clear weeds and bill the owner.

Backyard and recreational fires in unincorporated Colusa County are controlled by Air Pollution Control District burn-day rules and, in State Responsibility Areas, by CAL FIRE permits and suspensions. County Code Sec. 7-8 also restricts open flame in grass, brush and stubble from May 1 to November 1. A permissive burn day and a burn permit are generally required.

Unincorporated Colusa County has not written its own smoke-alarm ordinance. Instead, County Code Chapter 5 adopts the California Building, Residential and Fire Codes (Title 24), which set smoke-alarm and carbon-monoxide requirements. State law also requires working smoke alarms in all dwelling units, with carbon-monoxide alarms where fuel-burning appliances or attached garages exist.

Unincorporated Colusa County restricts where liquefied petroleum gas (LPG/propane) bulk storage may be located. County Code Chapter 7 limits bulk LPG storage near the developed water-district areas of Colusa, Arbuckle, Maxwell, Stonyford and other communities. Household propane tanks and installations also follow the adopted California Fire Code and state LPG safety standards.

Unincorporated Colusa County spans flat Sacramento Valley farmland and the western Coast Range foothills (Stonyford, Lodoga, Mendocino National Forest). Most of the unincorporated area is State Responsibility Area protected by CAL FIRE's Sonoma-Lake-Napa Unit, with the highest wildfire risk in the western foothills. State law PRC 4291 requires 100 feet of defensible space around structures in these zones.

Unincorporated Colusa County has no blanket residential-street ban on RVs or boats, but any vehicle left on a street over 120 consecutive hours is prohibited, large truck-trailers are barred from signed streets, and the zoning code bars storing trailers, boats, or campers in required parking spaces.

In unincorporated Colusa County only the road commissioner (under board authority) may place curb markings, which carry standard meanings: red (no stopping at any time), yellow (timed loading), and white (passenger loading). Parking contrary to a legible curb marking is prohibited.

Unincorporated Colusa County requires vehicles to park within 18 inches of the right-hand curb, prohibits angle parking unless approved and striped, bars double parking, and lets the road commissioner mark parking spaces and post location-specific restrictions.

Unincorporated Colusa County has no general overnight street-parking ban, but on streets posted with signs no vehicle may park more than 10 minutes between 2 a.m. and 6 a.m. (except Sundays and holidays), and no vehicle may sit on any street more than 120 consecutive hours.

Unincorporated Colusa County prohibits parking trucks and trailer combinations over 12,000 lb GVW on streets signed 'no parking,' caps loads on partially improved county highways at 16,000 lb, and follows California Vehicle Code authority on heavy commercial-vehicle parking.

Colusa County declares abandoned, wrecked, dismantled, or inoperative vehicles a public nuisance. On private property, Chapter 12B sets a 10-day-notice abatement process run by the sheriff; on county roads, a vehicle unattended 72+ hours is presumed abandoned and removed under state law.

Unincorporated Colusa County prohibits parking in front of any public or private driveway and bars parking near wheelchair access ramps. Where a driveway has no curb cut, the visibly paved or marked entrance area counts as the protected driveway.

Unincorporated Colusa County bars trucks and trailer combinations over 12,000 lb GVW from streets signed 'no parking,' caps gross weight on unpaved county highways at 16,000 lb, and relies on California Vehicle Code authority for oversized-vehicle parking limits.

Colusa County's municipal code has no dedicated electric-vehicle-charging ordinance. EV-charging infrastructure for new construction is governed by the statewide California Green Building Standards Code (CALGreen, Title 24, Part 11), which the county administers through its adopted Building Code (Chapter 5).

Unincorporated Colusa County uses yellow curbs for freight/passenger loading and white curbs for passenger loading, establishes bus zones, and requires off-street freight-loading spaces for larger commercial and industrial buildings under its Zoning Code.

The Colusa County Zoning Code (Chapter 44) sets no maximum fence height for the unincorporated county. The only height threshold that applies is the statewide California Residential Code building-permit exemption, under which a fence is exempt from a building permit only if it is not over 7 feet tall.

Unincorporated Colusa County has no zoning-permit requirement specific to fences. A fence needs a building permit from the Colusa County Building Division only when it exceeds the California Residential Code exemption of 7 feet in height; shorter fences are permit-exempt.

Colusa County's code has no boundary-fence cost-sharing rule, so California's statewide Good Neighbor Fence Law (Civil Code Section 841) controls. Adjoining owners are presumed to share equally in the cost of a fence dividing their properties, and a 30-day written notice is required before incurring shared costs.

The Colusa County Zoning Code sets no retaining-wall standard, so retaining walls are governed by the statewide building code the county enforces. Under the California Residential Code, a retaining wall not over 4 feet (measured from the bottom of the footing to the top of the wall) is permit-exempt unless it supports a surcharge.

Unincorporated Colusa County imposes no general design or construction standard for residential fences, but its Zoning Code requires that animals kept outdoors be fenced to keep them on the property, and abandoned-vehicle screening can be met with a solid six-foot fence. Pool barriers follow state law.

The Colusa County Zoning Code does not restrict fence materials in the unincorporated area - there is no list of prohibited or required fencing materials. Material choice is left to the owner, subject only to the building-code permit threshold and basic safety and screening requirements.

Unincorporated Colusa County does not regulate the materials used to build a fence. The Zoning Code names no approved or banned fencing materials, so owners may choose wood, vinyl, chain link, masonry, or wire, subject only to building-permit, pool-safety, and vehicle-screening rules.

In residential and transitional zones, Colusa County's Zoning Code allows up to four household pets, rising to six on lots over 10,000 square feet and eight on lots over one acre. A premises with more than five dogs kept for breeding, sale, or other commercial purposes is a "kennel" needing a license.

In unincorporated Colusa County, a dog off its owner's property must be on a leash held by a person able to control it. County Code Section 3-7 defines a "leash" as a rope, strap, or chain not to exceed six feet. Working herding dogs, licensed hunting dogs, and obedience-class dogs are excepted.

Colusa County is agricultural and allows commercial animals by right in all agricultural zones. In residential and transitional zones, keeping is capped by an "animal density points" system: chicken hens count one point each, and a 6,000-square-foot lot allows four points, scaling up with parcel size.

Colusa County's animal code contains no breed-specific or pit-bull ban. No "vicious" or "dangerous dog" breed provision appears in Chapter 3 or the Zoning Code. California law also bars any dog program that is specific as to breed, except for spay/neuter requirements.

Beekeeping is an established agricultural activity in Colusa County, whose Zoning Code defines an apiary as any place where one or more colonies or nuclei of bees are kept and treats apiculture as agriculture. There is no county hive-count cap; California law requires apiaries to be registered with the county agricultural commissioner.

Colusa County's code does not authorize keeping wild or exotic animals as pets, and California law controls. State Fish and Game Code Section 2118 and Title 14 regulations bar importing, transporting, or possessing restricted wild animals without a state permit, and permits are not issued to keep wild animals as pets.

Livestock keeping is a core right in rural Colusa County, where commercial animals are allowed by right in all agricultural zones. County Code Section 3-1 makes it unlawful to let livestock or fowl run at large or estray, and Chapter 34, the Right to Farm ordinance, protects established agricultural operations from nuisance claims.

Colusa County does not require cats to be licensed, vaccinated, or leashed; its licensing and rabies rules in Chapter 3 apply only to dogs. Cats count toward the household-pet limits in the Zoning Code, and California law requires shelters to hold stray cats and check for identification before disposition.

Colusa County's code has no standalone ordinance banning the feeding of wildlife. The county controls predatory animals through its "county trappers," and California Fish and Wildlife regulations restrict feeding and harassing big-game mammals such as deer and bears statewide.

Colusa County has no ordinance defining "hoarding" or capping animals at a residence, but its animal-nuisance provision, the kennel licensing threshold, the Zoning Code household-pet limits, and California's animal-cruelty laws together let authorities act when too many animals create unsanitary, dangerous, or neglectful conditions.

In unincorporated Colusa County, Chapter 7A (Weed Abatement) of the County Code requires owners to cut weeds and grass to three inches or less above ground level within fifty feet of structures before the annual 'plow down date' set by the County Fire Chiefs Association. The rule is a seasonal fire-prevention measure, not a general lawn-aesthetics ordinance.

Unincorporated Colusa County has no general ordinance dictating how or when private trees must be trimmed. Trimming is governed by sight-distance rules at intersections (Chapter 12D), firebreak/defensible-space requirements (Chapter 7 and state PRC 4291), and encroachment rules for vegetation overhanging county roads (Chapter 29). Routine pruning of trees on your own land needs no county permit.

Unincorporated Colusa County has no general tree-removal or oak-protection permit ordinance. Removing trees on your own property is generally allowed without a county permit, except within the fifty-foot riparian 'natural resource buffer area' along creeks, rivers, and wetlands, where cutting protective vegetation is prohibited under zoning Section 44-5.20. Most rural tree removal is unregulated by the county.

Chapter 7A of the Colusa County Code (Ord. No. 437) is the county's weed-abatement ordinance for the unincorporated area. It declares seasonal weed growth a recurring fire-safety nuisance and requires owners to clear weeds to three inches within fifty feet of structures by an annual plow down date. Fire districts can abate violations and bill owners.

Colusa County's zoning code (Section 44-3.10) regulates landscape water use for new and rehabilitated landscapes of 2,500+ square feet in urban zones, requiring efficient irrigation and limiting turf to 25% of landscaped area, and adopts California's Model Water Efficient Landscape Ordinance (MWELO). Everyday watering for existing rural homes is governed mostly by state law and well capacity.

Unincorporated Colusa County has no ordinance restricting residential rainwater harvesting. Capturing rain from rooftops for outdoor use is legal under California's Rainwater Capture Act of 2012 (AB 1750), which bars local agencies from requiring a permit to install or operate a rain barrel system. The State Water Board confirms no water right is needed for rooftop rainwater.

Colusa County encourages, but does not mandate, native and water-conserving plants. Zoning Section 44-3.10.020 directs that landscape plants 'should be selected from a County-approved list of native, water-conserving, and non-invasive species,' and defines xeriscape landscaping that may satisfy minimum landscaped-area requirements. Native riparian vegetation along creeks is separately protected under Section 44-5.20.

Unincorporated Colusa County has no ordinance specifically permitting or banning artificial/synthetic turf. The zoning landscaping standards (Section 44-3.10) focus on water-intensive natural turf (which 'should' be limited to about 25% of a landscaped area) and on impervious-surface limits in setbacks, so synthetic lawns are generally allowed subject to those drainage and setback rules. No county turf permit exists for homeowners.

Colusa County allows backyard composting under Chapter 32 (Solid Waste) of the County Code, which requires noncommercial home composting to be done in a 'nuisance-free, vector-free manner' using only waste from the resident's own home. Statewide, California's SB 1383 mandates organic-waste recycling; unincorporated-county organics collection is provided through Recology Butte Colusa Counties.

Colusa County Code Chapter 32 (Solid Waste Management) governs containers in unincorporated areas. Section 32-2(b) requires every waste generator to provide covered, leak-proof containers, and Section 32-2(d) makes the owner or occupant responsible for safe, sanitary storage that does not create a nuisance, attract vectors or cause odors.

Vacant land in unincorporated Colusa County is covered by two County rules: Chapter 7A (Weed Abatement) requires owners of vacant lots to clear weeds near adjoining improvements before the annual plow-down date, and Chapter 42 lets the County abate dumping, debris and inoperative vehicles on vacant parcels as a public nuisance.

Colusa County Code Chapter 7A (Weed Abatement, Ord. No. 437) requires every owner of land in the unincorporated county to remove weeds over three inches high near structures before an annual "plow-down date" set by the county fire chiefs association. The County declares weeds a seasonal, recurring fire nuisance.

Colusa County has no dedicated garage-sale or yard-sale ordinance in its County Code for unincorporated areas — there is no permit requirement, frequency cap or duration limit specific to residential sales. General zoning, signage and nuisance rules still apply.

Colusa County Code Chapter 42 (Code Compliance Provisions) is the County's blight tool for unincorporated areas. Section 42-2(j) defines a public nuisance to include accumulated garbage, illegally dumped solid waste, substandard buildings, and any condition that is a nuisance under California Civil Code Section 3479.

Solid-waste service is mandatory in unincorporated Colusa County under Chapter 32 (Sec. 32-8(a)). Curbside garbage collection is provided by the County's franchise hauler, Recology Butte Colusa Counties. Garbage and other putrescible waste must be removed for disposal at least once every seven days (Sec. 32-3(a)).

Colusa County Code Section 32-2(j) requires refuse containers to be placed for collection at ground level on the property, or within a road's public right-of-way "so as not to interfere with traffic, maintenance, access, parking or drainage." Containers must be stored to prevent upset and spillage and never below ground level.

Colusa County Code Chapter 32 addresses bulky waste through size/handling rules and disposal sites. Bulky items unsuitable for containers must be boxed, bundled or tied and kept to size limits (no longer than 48 inches, no more than 24 inches in diameter, not over 60 pounds) under Section 32-2(d)(3). Large appliances and furniture are excluded from transfer-station drop bins.

Colusa County Code Chapter 32 authorizes recycling and salvaging at approved County facilities but does not impose a separate mandatory residential recycling-separation ordinance. Recology Butte Colusa provides a curbside recycling cart in unincorporated areas, and the Maxwell Transfer Station accepts recyclables; California's AB 341/AB 1826 commercial recycling laws also apply statewide.

California's SB 1383 mandates organic-waste recycling statewide, but Colusa County — population under 70,000 — is one of 19 counties that qualify for CalRecycle's rural/low-population exemption. As a result, unincorporated Colusa County is not required to provide a separate organics (green/food-waste) collection cart during the exemption period.

In unincorporated Colusa County, campaign and political signs are temporary signs allowed without a permit under Section 44-3.50.040(b)(2) of the Zoning Code. They may not exceed 32 square feet in area or 12 feet in height, must be on private property with the owner's consent and out of the public right-of-way, and any sign over 7 feet tall requires a building permit.

Unincorporated Colusa County's Zoning Code has no sign category specifically for garage or yard sale signs. Such temporary signs fall under the general Sign Regulations of Section 44-3.50: they cannot be placed on public property or in the public right-of-way, and off-site signs (signs advertising something not on the parcel where the sign sits) are generally prohibited.

Unincorporated Colusa County has an outdoor lighting standard in Section 44-3.30 of the Zoning Code aimed at reducing light trespass and glare and maintaining views of the night sky. It requires full shielding and downward direction of fixtures, energy-efficient lamps, and limits illumination to the minimum needed for safety; certain high-intensity and roof-mounted lighting is prohibited.

Unincorporated Colusa County's Zoning Code controls light trespass through Section 44-3.30.010, which requires all outdoor lighting to be located, shielded, and directed so that no direct light falls outside the property line or into the public right-of-way. Fixtures must be fully shielded and aimed downward and away from adjoining properties.

Unincorporated Colusa County has no special ordinance singling out backyard barbecues; propane and charcoal grills are generally allowed at private homes. The applicable limits come from the adopted California Fire Code (small propane cylinders, safe placement away from buildings) and from common-sense fire caution during dry, high-wind conditions in the county's wildfire-prone western foothills.

Backyard smokers and barbecue pits in unincorporated Colusa County are treated as cooking devices, not open burning, so they are generally allowed without an air-district burn day or CAL FIRE permit. The main constraints are the adopted California Fire Code, the Air Pollution Control District's nuisance-smoke rules, and fire caution in the county's wildfire-prone western foothills.

Colusa County's Zoning Code sets minimum building setbacks by zone. In the main residential zones, primary structures need a 20-foot front setback (15 feet in R-4), a 15-to-20-foot rear setback, and a 6-to-10-foot side setback. Agricultural and commercial zones use different distances.

The Colusa County Zoning Code caps building height by zone. In the residential zones, the maximum structure height is 30 feet in Rural Residential, Single-Family, and Two-Family zones, and 40 feet in the Multiple-Family and Apartment-Professional zones. Agricultural and other zones allow taller structures.

The Colusa County Zoning Code does not cap residential lot coverage with a percentage. It controls building bulk through setbacks and maximum structure height, uses Floor Area Ratio limits in commercial and industrial zones, and limits impervious surfaces in required residential setbacks to 50 percent.

Unincorporated Colusa County has no general tree-removal permit ordinance and no heritage-tree or oak-protection permit program. The main county restriction on cutting trees is the fifty-foot riparian 'natural resource buffer area' along creeks, rivers, and wetlands (zoning Section 44-5.20), where altering protective vegetation is prohibited. Most tree removal on private rural land needs no county permit.

Unincorporated Colusa County does not set a single general park-closure hour, but two rules apply: a countywide minor curfew (Section 14-15.1) bars anyone under 18 from public places, including parks, between 11 p.m. and sunrise; and at the county-operated East Park Reservoir, day use is limited to 6 a.m. to 10 p.m. with quiet hours from 10 p.m. to 7 a.m. (Chapter 46).
