Capturing rooftop rainwater is legal in unincorporated Orange County, governed mainly by California's Rainwater Capture Act of 2012. No state water-rights permit is needed for rooftop capture used outdoors for non-potable purposes; standard rain barrels and small cisterns generally need no plumbing permit.
Unincorporated Orange County does not require native or drought-tolerant plants, but the County's Water Efficient Landscape Ordinance (adopted March 14, 2016) implements California's MWELO, limiting turf and favoring low-water plants on qualifying new and rehabilitated landscapes. State Civil Code 4735 protects low-water landscaping from HOA bans.
Unincorporated Orange County has no countywide ban on artificial turf. Synthetic lawns are treated as a landscaping/site-development matter and may need a permit if part of qualifying construction. California Civil Code 4735 bars HOAs from prohibiting artificial turf that resembles grass.
Unincorporated Orange County has not adopted a general native-tree preservation ordinance, so most private tree removal needs no county permit. A draft Protected Tree framework would require permits and 5:1 replacement, but it remains a proposal limited to large parcels in specific-plan canyon areas.
Home businesses in Mission Viejo are subject to strict limits on customer traffic to preserve the residential character of neighborhoods. Home occupations generally may not generate customer visits, deliveries, or parking impacts beyond what is normal for a residential use. Client visits are limited, and retail sales with walk-in customers are prohibited from home-based businesses.
California's Cottage Food Law (AB 1616 and AB 1266) allows Mission Viejo residents to produce and sell approved non-potentially-hazardous foods from their home kitchens.

HOA CC&Rs in Mission Viejo communities reinforce this prohibition. The restriction ensures home occupations remain invisible from the exterior.
Home occupations are allowed in all residential zones in Mission Viejo subject to a home occupation permit and compliance with operating conditions. The business must be incidental to the residential use, conducted entirely indoors, and generate no external impacts. Certain business types that conflict with residential zoning are prohibited regardless of permit status.
Mission Viejo requires a home occupation permit for businesses operated from residential properties. The permit ensures the business is compatible with the residential neighborhood by limiting signage, customer traffic, storage, and noise. Applications are processed through the Planning Division. The business must also obtain a city business license from the Finance Department.
California law preempts local zoning to allow small family daycare homes (up to 8 children) as a matter of right in all residential zones, including Mission Viejo. Large family daycare homes (9-14 children) require a use permit from the city. Both types require a license from the California Department of Social Services Community Care Licensing Division. HOAs may not prohibit small family daycare homes.
Mission Viejo pools must comply with California safety requirements including anti-entrapment drain covers, proper chemical storage, and maintenance standards. Pool equipment noise and drainage must not create nuisances for neighboring properties.

Any pool or spa capable of containing water 18 inches or more in depth must be enclosed by a barrier and meet drowning-prevention safety requirements. Portable spas must carry a UL or IAPMO listing.
Spas and hot tubs are treated like pools in unincorporated Orange County. The OC note sheet's enclosure and secondary-barrier rules apply, and under the California Pool Safety Act a spa holding more than 18 inches of water needs a building permit and at least two drowning-prevention features.

In unincorporated Orange County, any commercial vehicle over 25 feet long, 8 feet high, or 90 inches wide is barred from residential property under Codified Ordinance Sec. 3-13-4(15). On public streets, CVC 22507 lets the county restrict parking of vehicles six feet or more in height within 100 feet of an intersection, once signs are posted.
Orange County's Zoning Code Sec. 7-9-70.8 requires non-residential uses to provide off-street loading spaces, scaled by floor area - for example one loading space at 7,500-14,999 sq ft, rising to six spaces at 80,000-100,000 sq ft. On public streets, yellow and white painted curbs designate loading zones under California Vehicle Code 21458.
Curb colors in unincorporated Orange County follow California Vehicle Code 21458: red means no stopping, standing, or parking; yellow is for loading freight/passengers; white is for passenger loading; green is time-limited parking set by local ordinance. Only the local authority may paint or designate these curb markings - residents cannot paint curbs to reserve parking.
Persistent or habitual barking that disturbs neighbors violates Mission Viejo's nuisance noise provisions and Orange County Animal Care regulations. Complaints are handled through OC Animal Care and OC Sheriff.

Mission Viejo uses a nuisance-based noise standard rather than fixed decibel limits for most residential situations. The General Plan Noise Element establishes 65 CNEL as the threshold for residential land use compatibility.
Mission Viejo is a predominantly residential master-planned community with very limited industrial uses. Commercial noise reaching residential areas must comply with MVMC Title 11 nuisance provisions and zoning conditions.
Vehicle noise on public roads in unincorporated Orange County is governed mainly by California state law, not the County code. The California Vehicle Code requires adequate mufflers, bars modified or amplified exhaust, and treats a sound level over 95 dB(A) for light vehicles as non-compliant.
Mission Viejo effectively prohibits short-term rentals of less than 30 days in residential zones. Any rental operating in violation is subject to standard noise provisions, and noise complaints accelerate enforcement action.
Mission Viejo does not issue short-term rental permits in residential zones, so there is no local STR tax or fee structure. Any rental income from unauthorized STRs remains subject to state and county transient occupancy tax obligations.
Mission Viejo does not have night cap provisions for short-term rentals because STRs under 30 days are prohibited in residential zones. The concept of maximum nightly guest counts is inapplicable in this jurisdiction.
Mission Viejo does not issue STR permits and has no STR insurance requirements because short-term rentals are prohibited in residential zones. Property owners operating unauthorized STRs risk standard homeowner policy voidance.
Mission Viejo prohibits short-term rentals in residential zones, so no STR-specific occupancy limits exist. General occupancy is governed by building and fire codes based on the dwelling's permitted capacity.

Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) for unincorporated areas does NOT require the home to be the owner's primary residence. Non-owner-occupied whole-home rentals are allowed with a permit. The only residency-style restriction is that Accessory Dwelling Units cannot be used as short-term rentals.
Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) does NOT require the host to be present during stays in unincorporated areas. Unhosted, whole-home rentals are permitted. The ordinance instead requires a 24/7 reachable owner or designee contact and guest-responsibility records.
Orange County may revoke a short-term rental operator permit after repeated nuisance, noise, or occupancy violations at the same property. The county uses a graduated enforcement approach with warnings, fines, and ultimately permit revocation for habitual offenders.
Hosting platforms like Airbnb and VRBO are expected to display valid OC short-term rental permit numbers on listings and may face liability for facilitating unpermitted rentals in unincorporated Orange County. The county can pursue platform-level enforcement when listings lack permits.
Orange County does not impose a separate extended home-share category for partial-unit rentals exceeding hosted-only night caps. All short-term rentals in unincorporated areas operate under a single STR operator permit regime regardless of duration.
Open burning is prohibited throughout Mission Viejo under Orange County Fire Authority regulations and South Coast Air Quality Management District Rule 444. No recreational, agricultural, or debris burning is allowed in open areas. Violations carry AQMD fines and potential OCFA enforcement action.
Mission Viejo requires 100 feet of defensible space around structures in fire hazard areas, enforced by OCFA. Annual brush clearance inspections occur in spring, and non-compliance results in abatement at the property owner's expense.
Backyard fires in Mission Viejo are limited to contained fire pits and outdoor fireplaces that meet OCFA standards. Open fires and bonfires are prohibited. All outdoor fire use is suspended during Red Flag Warnings.
Mission Viejo follows OCFA and California Fire Code regulations for residential propane and flammable gas storage. Small portable propane cylinders for barbecues are permitted but must be stored outdoors, while larger tanks require permits and setback compliance.
All fireworks, including so-called 'safe and sane' varieties, are completely prohibited in Mission Viejo. The Orange County Fire Authority enforces fireworks violations with significant fines, especially during high-risk fire weather.
California law requires working smoke alarms in every bedroom, outside each sleeping area, and on every level of a dwelling. Carbon monoxide alarms are required in all residences with fossil-fuel-burning appliances or attached garages. Mission Viejo enforces these requirements through OCFA inspections and upon sale or transfer of property per California Civil Code Section 1102.6d.
Portions of Mission Viejo along the eastern and southern hillside edges are designated as Very High Fire Hazard Severity Zones by CAL FIRE and OCFA. Properties in these zones must maintain 100 feet of defensible space, use fire-resistant building materials, and comply with OCFA vegetation management inspection programs. Annual brush clearance is required before fire season.
Mission Viejo allows fire pits subject to SCAQMD Check Before You Burn restrictions and OCFA fire safety standards. Properties near wildland-urban interface areas may require OCFA review for new outdoor fire features. Gas-fueled fire pits are preferred over wood-burning units.
Mission Viejo requires permits for retaining walls exceeding 4 feet in height including any surcharge. Retaining walls must be engineered and inspected to ensure structural stability, proper drainage, and compliance with setback requirements.

Mission Viejo Municipal Code Section 9.20.015 (General Standards) sets the citywide fence and wall height rules. A fence, wall, or hedge up to six feet may be located anywhere on a parcel except in a traffic safety sight area, a required front setback, or a street-side setback - where the maximum is 42 inches. When ground levels differ between adjoining parcels, the height of a property-line fence is measured from the finished grade of the highest contiguous parcel. Both sides of perimeter walls or fences must be architecturally treated. California Civil Code Section 841 governs cost-sharing of shared boundary fences with adjoining owners.
Unincorporated Orange County fences must comply with Zoning Code Section 7-9-64: height limits by setback area, a 3.5-foot cap in sight-visibility triangles at driveways and intersections, no chain-link in front setbacks, and a building permit for fences or walls over six feet. Swimming-pool fencing has separate state safety rules.
Most fence materials are allowed in unincorporated Orange County so long as height and sight-line rules in Zoning Code Section 7-9-64 are met. The only material rule in that section bars chain-link in a required front setback. Walls over six feet must be engineered through a building permit.
OC Development Services requires a building permit for any fence or wall over six feet tall (over 42 inches in a front-yard setback), and walls over six feet must be engineered. Fence or wall heights above the Zoning Code limits also require a Site Development Permit or Use Permit.
The Orange County Zoning Code restricts chain-link fencing in required front setbacks but does not, in Section 7-9-64, set a general list of prohibited fence materials such as barbed wire or razor wire. Material and engineering standards instead come from building-permit review for walls and fences over six feet.
Shared boundary fences in unincorporated Orange County are governed by California Civil Code Section 841, the Good Neighbor Fence Law. Adjoining owners are presumed equally responsible for the reasonable cost of a boundary fence, and a 30-day written notice is required before charging a neighbor for the work.
Mission Viejo and the State of California restrict ownership of exotic animals. Many species require California Department of Fish and Wildlife permits, and the city's animal control provisions and HOA rules may impose additional limitations on exotic pet ownership.
Mission Viejo Municipal Code Section 10.01.200 requires that any dog on public property be restrained by a substantial chain or leash not exceeding six feet in length, and be under the charge of a person competent to exercise care, custody, and control of the dog - unless the owner or operator of that public property has granted written permission for off-leash use. The rule applies on city streets, sidewalks, parks, and trails (other than designated off-leash areas). California Food and Agricultural Code Section 30951 authorizes local agencies to impound dogs running at large. Animal services for Mission Viejo are administered by the city's Animal Services Center.
Residential beekeeping is effectively prohibited in Mission Viejo. The City Council rejected a proposed beekeeping ordinance in May 2021 by a 4-1 vote. Under the existing nuisance code (§9.59.110), bees kept or bred in violation of the municipal code are designated a nuisance.
Keeping horses, cattle, sheep, swine, and goats in unincorporated Orange County is regulated by the County Zoning Code's animal-keeping standards. Equine require a minimum parcel of one acre unless the underlying zone says otherwise, and all such livestock must be kept at least 50 feet from neighbors' homes and 20 feet from any property line.
Orange County has no leash law for cats and cat licensing is optional under OCCO 4-1-85. However, cats are still 'animals' under OCCO 4-1-49, so an owner may not let a cat trespass onto another person's private property without consent. Owning four or more cats over four months old requires an Animal Permit under OCCO 4-1-76.
Orange County addresses hoarding through its Animal Permit limits and through California's animal-cruelty law. Owning four or more dogs or cats over four months old requires an Animal Permit (OCCO 4-1-76). Keeping animals in conditions that deprive them of food, water, or shelter is criminal neglect under California Penal Code 597, a wobbler punishable as a misdemeanor or felony.
Orange County charges substantially higher dog license fees for unaltered dogs and requires spay or neuter for impounded animals before release, encouraging sterilization and reducing shelter intake countywide.
Orange County encourages residents to haze coyotes, secure attractants, and report aggressive encounters under a coordinated management plan run with OC Animal Care, OC Parks, and California Department of Fish and Wildlife.
Orange County requires dogs four months and older within OC Animal Care jurisdiction to be microchipped before or at the time of license issuance, ensuring lost pets can be returned quickly to owners.
Under OCCO 4-1-76, anyone in unincorporated Orange County who keeps four or more dogs or four or more cats over four months of age must obtain an annual Animal Permit from OC Animal Care. Up to three dogs and three cats may be kept without it. All dogs four months and older must be licensed (OCCO 4-1-70).
California AB 485 prohibits pet stores in Orange County from selling dogs, cats, or rabbits unless sourced from animal shelters or approved rescue organizations, and OC Animal Care inspects compliance under the state mandate.
Orange County zones veterinary hospitals into commercial and limited industrial districts and requires conditional use permits when overnight boarding, outdoor runs, or large-animal services are part of the operation.
Orange County does not ban any dog breed. California Food & Agricultural Code 31683 prohibits cities and counties from adopting breed-specific dog laws, except for spay/neuter or breeding programs. Instead, OC Animal Care regulates individual dogs through the 'potentially dangerous' and 'vicious' dog process under OCCO 4-1-23 and 4-1-95, based on behavior rather than breed.
Keeping chickens and other fowl in unincorporated Orange County is governed by the County Zoning Code's animal-keeping standards (section 7-9-105, Pets and animals). Poultry and birds are limited by lot area, roosters and peacocks are generally not allowed in residential zones, and birds must be kept set back from neighboring dwellings and property lines.
Orange County's Title 4 animal ordinances do not set a general countywide ban on feeding wildlife, so the controlling rules come from California state law. Title 14 CCR 251.3 prohibits knowingly feeding big game mammals (deer, elk, antelope, bear, bighorn sheep), and 14 CCR 251.1 bars harassment that disrupts wildlife. Feeding that attracts predators can also create a public-nuisance problem.
Mission Viejo allows garage conversions to ADUs or living space subject to California state ADU law and local building codes. Converting a garage to an ADU does not require replacement parking under current state regulations.
Mission Viejo regulates sheds and accessory storage structures through building and zoning codes. Small sheds under 120 square feet typically do not require a building permit, but must comply with setback and height requirements and often need HOA approval.
Mission Viejo does not have a separate tiny-home ordinance. A 'tiny home' is treated as either an Accessory Dwelling Unit (ADU) under MVMC Section 9.10.020 and California Government Code Section 65852.2, a tiny house on a foundation built to CRC Appendix AX, or a recreational vehicle - which may not be used as a permanent dwelling. Movable tiny houses on wheels are not permitted as residences in Mission Viejo.
Carports in Mission Viejo are regulated under MVMC Title 9 (Land Use/Zoning), with parking standards in Chapter 9.25 and residential development standards in Chapter 9.10. A two-car carport must provide a minimum unobstructed inside dimension of 20 ft by 20 ft (30 ft by 20 ft for three cars). Carports require a building permit and may not be located within a required front, side, or rear setback unless expressly authorized by the zone.
Mission Viejo permits accessory dwelling units and junior accessory dwelling units in residential zones consistent with California state ADU law. The city processes ADU applications ministerially and cannot impose subjective design review on qualifying projects.
Mission Viejo has no local rent control ordinance. California's Tenant Protection Act (AB 1482) caps annual rent increases at 5% plus CPI or 10%, whichever is lower, for qualifying properties. Single-family homes are generally exempt if proper notice is given.
Mission Viejo does not require rental property registration or a landlord license. Rental properties must comply with building code and property maintenance standards. Business licenses may be required for property management companies operating within the city.
Mission Viejo follows California's just cause eviction protections under AB 1482. After 12 months of occupancy, tenants in qualifying properties can only be evicted for at-fault reasons (nonpayment, lease violation) or no-fault reasons (owner move-in, demolition) with relocation assistance.
California AB 12 caps security deposits at one month's rent for nearly all Orange County residential tenancies starting July 2024, regardless of furnished or unfurnished status. Small mom-and-pop landlords retain a limited two-month exception.
Under California AB 1482, no-fault evictions in Orange County rental units (owner move-in, withdrawal from market, substantial remodel, government order) require landlords to provide one month's rent in relocation assistance or waive the final month's rent.
Orange County landlords using a no-fault eviction under AB 1482 must pay relocation assistance equal to one month of current rent, or waive the tenant's final month, regardless of tenant income or household size. OC has no enhanced county-level relocation tier.
California prohibits Orange County landlords from refusing to rent to applicants because they use a Section 8 housing-choice voucher or other government rental subsidy. Source-of-income protection became statewide under SB 329 in 2020.
California Civil Code 1940.2 prohibits Orange County landlords from using force, threats, fraud, utility cutoffs, or repeated false-eviction filings to coerce tenants into vacating. OC has not adopted a separate county-level tenant-anti-harassment ordinance like LA's TAHO.
California AB 1482 (Tenant Protection Act of 2019) requires landlords countywide in Orange County to provide written notice of statewide rent caps and just-cause eviction protections, or to certify a property's exemption status, in every lease and renewal.
The Orange County Housing Authority (OCHA) administers Section 8 housing-choice vouchers for most unincorporated areas and many cities. Landlords are required to accept voucher applicants under California source-of-income protection law, with OCHA setting payment standards.
California evictions run through the unlawful detainer process. Under Code of Civil Procedure § 1161, nonpayment requires a 3-day notice to pay rent or quit (excluding weekends and holidays), and lease violations require a 3-day notice to cure or quit. No-fault terminations of covered tenancies require 30, 60, or 90 days. Self-help lockouts are illegal.
California landlords must keep rentals fit to live in. Civil Code §§ 1941 and 1941.1, reinforced by Green v. Superior Court, imply a warranty of habitability covering plumbing, heat, water, electricity, and sanitation. If repairs fail after notice, a tenant may repair and deduct up to one month's rent under § 1942 or withhold rent.
California Civil Code § 1954 limits when a landlord may enter a rented home. Except in emergencies, abandonment, or with tenant consent, the landlord must give reasonable written notice (24 hours is presumed reasonable) and may enter only during normal business hours, for specific permitted reasons such as repairs, inspections, or showings.
California sets no fixed dollar or percentage cap on rent late fees, but a late fee in a residential lease is treated as liquidated damages. Under Civil Code § 1671, such a fee is valid only if it reasonably estimates the landlord's actual loss from late payment; arbitrary penalty fees are unenforceable.
To end a California month-to-month tenancy, a tenant gives 30 days' written notice. A landlord gives 30 days if the tenant has lived there under a year, or 60 days if a year or more, under Civ. Code § 1946.1. AB 1482 requires just cause after 12 months; military and DV tenants may exit early.
California requires written notice before raising a month-to-month tenant's rent. Under Civ. Code § 827, increases of 10% or less in 12 months need 30 days' notice; increases above 10% need 90 days' notice. AB 1482 separately caps yearly increases on covered units.
California adverse possession requires five years of continuous, open, hostile possession AND payment of all property taxes during that period under Code of Civil Procedure § 325. A squatter or trespasser who has not paid taxes gains no ownership and can be removed by unlawful detainer, ejectment, or a police trespass action.
Mission Viejo requires single-stream recycling and organic waste diversion under California SB 1383. Food scraps and yard waste go in the green cart. Recyclables include paper, cardboard, glass, metal, and plastics #1-5 and #7. No plastic bags in recycling.
Mission Viejo provides curbside trash, recycling, and green waste collection through Ware Disposal (now Republic Services). Residential pickup is once weekly. Carts must be placed at the curb by 6:00 AM on collection day and retrieved by 8:00 PM the same day.
Mission Viejo residents receive bulky item pickup through Ware Disposal by appointment. Items include furniture, appliances, and mattresses. The city also hosts periodic community cleanup events. Household hazardous waste goes to Orange County HHW collection centers.
Trash, recycling, and green waste carts must be stored out of public view when not set out for collection. On collection day, carts go curbside by 6:00 AM with handles facing the house, lids closed, and spaced at least 3 feet apart. Carts must be retrieved by 8:00 PM.
Mandatory organics recycling in unincorporated Orange County is driven by California SB 1383, not a unique county rule. Effective January 1, 2022, all residences and businesses must separate organic waste (food scraps and yard waste) into the organics cart. The County adopted Ordinance No. 21-011 to implement SB 1383, with enforcement beginning January 1, 2024. Residents cannot opt out.
Mission Viejo does not operate a formal no-knock registry. Residents can post 'No Soliciting' signs which solicitors are legally required to respect under the municipal code. Most Mission Viejo HOA communities have their own solicitation policies and gated entry that limits unwanted visitors.
Mission Viejo regulates door-to-door solicitation through its municipal code. Solicitors must obtain a city permit before going door to door. Solicitation is prohibited before 9:00 AM and after 8:00 PM. Solicitors must respect 'No Soliciting' signs and leave immediately when asked.
Food trucks operating in Mission Viejo must obtain a business license from the city and a health permit from the Orange County Health Care Agency. Mobile food facilities may operate on private property with the property owner's written consent but are restricted from operating on public streets and in residential zones without special event authorization. The city regulates hours of operation and location requirements.
Mission Viejo does not designate specific public vending zones for food trucks. Mobile food vendors operate primarily on private commercial property with owner permission or at city-sanctioned special events in parks and community areas. The city periodically hosts food truck events at venues such as the Norman P. Murray Community and Senior Center.
Mission Viejo restricts drone use in city parks and over city facilities. Federal FAA rules govern all recreational drone operations. Parts of Mission Viejo fall near controlled airspace from Joint Forces Training Base Los Alamitos and John Wayne Airport. LAANC authorization may be required.
Commercial drone operators in Mission Viejo must hold an FAA Part 107 Remote Pilot Certificate. City permits may be required for operations over city property or during public events. Proximity to John Wayne Airport requires airspace awareness and possible LAANC authorization.
Mission Viejo requires permits for removing protected trees on private property. Trees with trunks 10 inches or more in diameter at breast height (DBH) are generally protected. The city's strong tree preservation policy requires justification for removal and replacement planting.
When tree removal is approved, Mission Viejo requires replacement planting at a minimum 2:1 ratio. Replacement trees must be minimum 24-inch box specimens of approved species. Heritage and significant trees may require enhanced replacement ratios up to 3:1 or 4:1.
Mission Viejo has a heritage tree program protecting significant, mature, and historically important trees. Heritage trees receive the highest level of protection and cannot be removed except under extraordinary circumstances. The program covers both public and qualifying private trees.
Orange County protects coast live oak, Engelmann oak, California sycamore, and other native trees in unincorporated areas through grading, hillside, and oak woodland conservation provisions tied to CEQA review.
Mission Viejo limits residential building height to 35 feet or two stories in most single-family zones. Height is measured from finished grade to the highest point of the roof. Height exceptions may apply to architectural features, chimneys, and antennas subject to specific limits.
Mission Viejo limits lot coverage (the percentage of a lot covered by structures) in residential zones, typically to 40-50% depending on the zone. All roofed structures count toward lot coverage including the main house, garage, ADUs, covered patios, and accessory structures.
Mission Viejo zoning code establishes minimum setback requirements that vary by zone. Residential zones typically require 20-foot front setbacks, 5-foot side setbacks, and 15-20 foot rear setbacks. Setback reductions may be available through the planning process for specific conditions.
Mission Viejo parks are open from dawn to dusk unless otherwise posted. The city closes parks and trails after dark. Oso Creek Trail and other open space areas have posted hours. Violators are subject to citation by OC Sheriff's Department.
Mission Viejo enforces a juvenile curfew for minors under 18. Minors are prohibited from being in public places during curfew hours without a parent, guardian, or authorized adult. Exceptions include employment, emergencies, and First Amendment activities.
Mission Viejo HOA assessments are governed by the Davis-Stirling Common Interest Development Act. Associations must provide annual budgets, disclose reserves, and follow specific procedures for regular and special assessments. Regular assessments cannot increase more than 20% per year without member approval. Special assessments exceeding 5% of the annual budget require a membership vote.
Most Mission Viejo neighborhoods require homeowners to submit exterior modification plans to their HOA architectural review committee before making changes. The Mission Viejo Association and successor HOAs enforce detailed design guidelines covering paint colors, roofing materials, landscaping, fencing, and structural additions. Unapproved modifications may be required to be removed or restored at the homeowner's expense.
Mission Viejo HOA boards must follow the Davis-Stirling Act's open meeting requirements, including providing at least four days' notice of regular meetings and posting agendas. Members have the right to attend and speak at board meetings. Executive sessions are limited to specific topics including litigation, personnel, and discipline. Annual elections must use secret ballots with an independent inspector of elections.
Mission Viejo HOAs enforce CC&Rs through a graduated process of notices, hearings, fines, and potential legal action. Common violations include unapproved exterior modifications, parking violations, landscaping non-compliance, and noise complaints. Under the Davis-Stirling Act, homeowners must be given notice and an opportunity to be heard before fines are imposed. Fines typically range from $50 to $200 per violation with escalation for repeated offenses.
Mission Viejo homeowners in disputes with their HOA must attempt Internal Dispute Resolution and Alternative Dispute Resolution before filing lawsuits under the Davis-Stirling Act. IDR involves a direct meeting with a board member, while ADR involves mediation or arbitration through a neutral third party. The city does not directly mediate HOA disputes but the Orange County Superior Court provides mediation resources.
California HOAs may fine members for rule violations, but only under a published schedule of fines and after strict due-process steps.
