Missouri's Propane Safety Commission adopts uniform statewide standards for liquefied petroleum gas storage, handling, and transportation. The rules incorporate NFPA 58 by reference and preempt conflicting local requirements for licensed propane operations under Chapter 323 RSMo.
Missouri has no statewide ADU mandate. Florissant's Zoning Code (Chapter 405) does not authorize accessory dwelling units in single-family R-1 through R-4 districts. Section 405.085 limits R-1 to single-family dwellings plus customary accessory buildings. A duplex requires R-5 zoning.
Florissant treats sheds and storage buildings as accessory structures under the Zoning Code (Chapter 405) supplementary district regulations and the Building Code (Chapter 500). The published Public Works guideline caps shed height at 18 feet, and not exceeding the height of the residence; structures within 6 feet of the house must match the house setback, and any shed of 200 square feet or more requires construction plans submitted with the building permit application.
A building permit is required for residential attached or detached garages, attached carports, sundecks, and smokehouses (regardless of size for smokehouses). Smokehouses on residential property are limited to 25 sq ft and 8 ft height.

Above-ground pools exceeding 24 inches deep, 250 sq ft in area, or equipped with a recirculation system require a building permit. The same 48-inch barrier and gate requirements apply. Setback review through the Zoning Review Section is required.
A building permit is required for any swimming or bathing pool exceeding 24 inches deep, 250 sq ft in area, or equipped with a water recirculation system — whether in-ground or above-ground. Setback review by the Zoning Review Section is also required.
Public pools (including subdivision pools) in St. Louis County must comply with the federal Virginia Graeme Baker Pool & Spa Safety Act. Drain covers meeting ASME/ANSI A112.19.8 are required. A lifeguard is mandatory for pools with combined water surface ≥2,000 sq ft.
Florissant's general noise ordinance (§210.750) sets a de facto start time of 7:00 a.m. for activities that could disturb neighbors. No separate specific construction-hours ordinance was identified. Loud construction before 7:00 a.m. would likely violate the general noise prohibition.
Florissant regulates amplified music under the general noise ordinance. Sound amplification permits available for events. MO Rev. Stat. §574.010 applies.
Florissant City Code §210.750 prohibits loud, unnecessary, or unusual noise that disturbs neighborhood peace. Operating radios, TVs, or music devices between 11:00 p.m. and 7:00 a.m. that are plainly audible at 50 feet from the building is prima facie evidence of a violation.
Florissant Code §205.065 prohibits keeping animals that cause loud noises. Dogs creating persistent barking noise that disturbs neighbors may be cited under §205.065 (animals) and §210.750 (noise). Animal Control: 314-615-0650.
SLCRO §716.078 bans operating an ATV on private property within 100 ft of another's residence or on any public paved road or sidewalk. Pocket bikes (≤49cc) are 'motor vehicles' subject to the county noise ordinance and require a driver's license and helmet.
Aircraft noise regulation in Missouri is preempted by federal law under the Federal Aviation Act and related FAA regulations. Neither Missouri state law nor local municipalities may impose curfews, altitude restrictions, or noise standards on aircraft operations.
Florissant's Zoning Code (Chapter 405) caps residential fences at 6 feet in side and rear yards in all R districts. No fence is permitted in the required front yard except by Planning and Zoning Commission review. A fence permit from the Building Commissioner is required before construction.
MO Rev. Stat. §272.010 provides partition fence cost-sharing for rural/agricultural land. Urban residential: each owner responsible for their own fence.
A building permit is required for any retaining wall over 3 ft in height (measured from the non-retained grade), over 2 ft if it supports a surcharge load, located closer than its height to a property line, or with a fence/guardrail on top exceeding 6 ft total.
SLCRO bans barbed wire and electrical fencing in residential areas of unincorporated St. Louis County. Property-maintenance rules also prohibit fences with peeling paint, rust, or structural damage.
Florissant prohibits short-term rentals and vacation rentals in all residential zoning districts under Section 605.462 of the Code, leaving only B-3 lodging establishments, bed and breakfasts, and private clubs as legal overnight-lodging uses. Whichever lodging form applies, guests are bound by the citywide peace-disturbance ordinance at Section 210.750, which makes any loud, unnecessary, or unusual noise that disturbs neighbors a municipal offense.
Because Florissant's Section 605.462 bans short-term and vacation rentals in residential zoning districts, the only lawful overnight lodging in the city is a B-3 bed and breakfast, lodging establishment, or private club, each of which must satisfy the off-street parking standards in Chapter 405 (Zoning Code). Guest parking on residential streets is governed by the citywide street-parking rules in Chapters 355 and 365 and the supplementary district regulations of the Zoning Code.
Florissant amended its code to prohibit short-term rentals (Bill No. 9695, amending Article XVII Residential Rental Real Estate). All residential rental properties require a license; STRs appear to be prohibited under the residential rental licensing framework.
Since STRs are prohibited in Florissant, no STR-specific tax structure applies. Standard Missouri state sales tax (4.225%) and any applicable city sales taxes apply to lodging in general. Operating a prohibited STR exposes operators to fines.
STR occupancy in unincorporated St. Louis County is effectively governed by the family definition in SLCRO §1003.020: an individual or related persons, or up to 3 unrelated persons living as a single non-profit housekeeping unit using no more than 2 kitchens.
Florissant allows home occupations as accessory use in residential zones. Home occupation permit required. MO Cottage Food Law allows limited home food sales.

Missouri RSMo 196.298 expressly preempts local health departments from regulating cottage food production. Home producers may sell baked goods, jams, jellies, and dried herbs directly to consumers without state inspection or permits.
Missouri does not preempt local breed-specific legislation. Some MO cities have breed bans. MO Rev. Stat. §273.033 covers dangerous dogs based on behavior.
Florissant requires dogs on leash in public. Off-leash in designated parks only. MO Rev. Stat. §273.033 covers dangerous dogs. Strict liability for bites (§273.036).
Florissant's animal regulations (Chapter 205) follow state law (RSMo §578.023) prohibiting dangerous wild animals without local law enforcement registration. Wild, undomesticated, and inherently dangerous animals are not permitted in Florissant's residential areas.
No specific Florissant beekeeping ordinance was identified. Missouri Department of Agriculture oversees apiary inspections under RSMo Chapter 264. Beekeeping must not create a nuisance under §210.750. Check with the city's Building/Zoning Division for current status.
Residents in unincorporated St. Louis County may keep chickens as pets but may not breed them for sale or sell eggs. Chickens must not become a public nuisance under SLCRO §611.210. Each incorporated city sets its own poultry rules.

In unincorporated St. Louis County, a single-family residence may keep at most 3 dogs, OR 5 cats, OR a combination of 5 dogs and cats with no more than 3 dogs at any time.
Missouri RSMo 578.009 and 578.012 universally criminalize animal neglect, abandonment, and abuse, applying to hoarding situations regardless of municipal limits and authorizing courts to order cost recovery, animal forfeiture, and ownership bans.
Florissant has floodplain areas subject to FEMA Flood Insurance Rate Maps (FIRMs) administered by SEMA. Land disturbance permits are required for significant activities in or near flood zones. The city adopted the 2021 IRC with Appendix AJ (existing buildings) and other flood-relevant appendices.
SLCRO §1115.105.2 exempts site/land-disturbance work of less than 30 cubic yards of soil moved AND less than 2,000 sq ft of disturbed area from the building-permit requirement. Larger projects require a grading permit and erosion controls.
SLCRO §1005.230 (Grading) and §1114.200 (Design Requirements) require grading permits or approved improvement plans before any grading. Erosion and siltation controls are mandatory. Grading that alters watersheds is prohibited.
Bulky residential waste must be stored neatly at least 3 ft behind the main residential structure (SLCRO §607.120). Two bulky pickups per year are included in the minimum service level. Scrap tires and major appliances are excluded.
St. Louis County's single-stream curbside recycling accepts boxboard, cardboard, milk/juice cartons, newspaper, office paper, plastics #1-5 and #7 (no #6 Styrofoam), glass containers, and aluminum/tin cans. Plastic bags, scrap metal, and hazardous waste are excluded.
SLCRO §607.310 prohibits depositing waste on any property without a valid landfill, transfer, or composting license. The dumper and any property owner who allowed dumping are both liable. Dumping in creeks or waterways is separately prohibited under §607.810.
Under SLCRO §607.060 and §607.182, yard waste (leaves, grass clippings, garden trimmings, tree limbs <6 in diameter, Christmas trees) is banned from landfill disposal and cannot be put in with household trash. Licensed haulers must offer yard-waste collection as an optional service.
SLCRO §607.181 requires that all 1- and 2-family residences in St. Louis County receive: once-weekly trash collection, once-weekly recycling, and twice-yearly bulky waste pickup. All county-licensed residential haulers must provide all three components.
SLCRO §607.120 requires trash and recycling containers to be stored at least 3 feet behind the front of the main residential structure. Containers may go to the curb no earlier than dusk the day before pickup and must be returned the same day as collection.
Garage and yard sale signs are prohibited in the public right-of-way under SLCRO §1003.168 and §710.010. Signs may only be placed on private property with the owner's permission. Real-estate signs are also limited to the property being sold.
Decorative displays for holidays may be displayed no more than 30 days before and 7 days after the specific holiday under SLCRO §1003.168. Displays on private property only — no public right-of-way placement.
Political campaign signs are permitted in all zoning districts under SLCRO §1003.168. Maximum 8 sq ft per sign, 16 sq ft total per lot. Signs must be on private property and removed within 7 days after the election.
Chapter 1110 (Property Maintenance Code) requires foundations, roofs, gutters, fences, decks, sheds, sidewalks, and exterior paint to be kept structurally sound, with no peeling/flaking paint and no rust. Violation notices give 7-30 days to cure.
Properties vacant 90 days or more with an active nuisance (tall grass, debris, broken windows) are subject to monthly inspections by the Department of Public Works Problem Properties Unit. Inspection costs are billed back to the owner as a special tax bill.
St. Louis County does not impose a private snow-removal mandate on homeowners. County plows clear arterial and collector roads first; subdivision roads should be addressed within 24 hours of storm end. Residents are asked to park off streets during storms.
SLCRO §607.060 and §607.070 require residential waste containers to be galvanized metal, rubber/fiberglass, or non-absorbent plastic, 20-35 gallons, leak-proof, fly-tight, properly covered. Storage at least 3 ft behind the main residential structure (§607.120).
Residential solar photovoltaic installations in St. Louis County require both structural and electrical permits, governed by the 2014 NEC and SLCRO Chapter 1102. A licensed electrical contractor must perform the install. Electrical permit fee is $156.
Missouri RSMo 442.404 voids deed restrictions and HOA covenants that prohibit or effectively prohibit rooftop solar panel installation, and the Missouri Supreme Court confirmed retroactive application to pre-existing covenants in 2026.
SLCRO §804.040 requires every solicitor or peddler in unincorporated St. Louis County to obtain a license from the Department of Revenue before any door-to-door activity. Licenses must be displayed on request and solicitors must leave any premises when asked.
Missouri's Telemarketing No-Call Law preempts certain solicitation practices statewide, and the Merchandising Practices Act gives consumers a three-day right to cancel home solicitation sales. These statutory rights apply universally regardless of local solicitor permits.
Chapter 825 (Residential Rental Property License Code) requires owners of rental property in unincorporated St. Louis County to obtain a license and submit to periodic inspections. §825.600 sets the application process and inspection program.
Since July 2007, all owner-occupied and rental housing in unincorporated St. Louis County requires a re-occupancy permit each time a new occupant moves in. SLCRO §1110.1045 requires disclosure of this requirement at conveyance or rental.
Missouri uses two main paths. For nonpayment, the rent-and-possession action (RSMo 535.010 et seq.) requires the landlord to demand the rent, then file a verified statement asking the court to issue a summons. For lease violations involving unlawful or hazardous use, RSMo 441.040 requires ten days' notice to vacate before re-entry.
Missouri recognizes an implied warranty of habitability through case law (Detling v. Edelbrock, 1984), requiring residential premises to be fit and safe to live in. RSMo 441.234 separately lets qualifying tenants repair code-violating defects and deduct the cost, capped at the greater of $300 or one-half the periodic rent.
Missouri statute governs lease termination notice statewide and does not require landlords to demonstrate just cause to end month-to-month or expired-term tenancies.
Missouri has no statutory requirement governing landlord entry. Chapter 441 is silent on advance notice, permissible hours, or reasons for entry into a tenant's dwelling. The lease itself is the primary control, and a tenant who is wrongfully excluded or harassed by repeated entries may sue for breach of the rental agreement.
Missouri sets no statutory cap on residential late fees and requires no statutory grace period. The amount is governed by the lease, subject only to the general common-law rule that a fee must be a reasonable estimate of damages rather than an unenforceable penalty. There is no late-fee provision in Chapter 441.
Under RSMo 441.060, a month-to-month or periodic tenancy is ended by one month's written notice from either party, taking effect on a rent-paying date at least one month after receipt. Tenancies at will or by sufferance also require one month's written notice. Mobile-home lot tenancies require sixty days' notice.
Missouri expressly preempts local rent control. Under Mo. Rev. Stat. § 441.043, no county or city may enact, maintain, or enforce any ordinance regulating the rent charged for privately owned residential or commercial rental property. There is no statewide rent cap, and no Missouri city has a general rent-control program.
Missouri has no statute setting an advance-notice period for rent increases and no rent control. For a month-to-month tenancy, a landlord effectively raises rent by terminating the existing term with one month's written notice under RSMo 441.060 and offering new terms. Mid-lease increases are barred by the lease itself.
Missouri caps residential security deposits at two months' rent. After a tenancy ends, the landlord has 30 days to return the deposit or deliver a written itemized list of damages withheld. The tenant may be present at the move-out inspection, and a landlord who wrongfully withholds owes twice the amount withheld.
Missouri requires ten years of possession to claim land by adverse possession. RSMo 516.010 bars an action to recover real property unless the owner was seized or possessed within ten years before suit. A squatter's possession must also be actual, open, notorious, exclusive, hostile, and continuous for the full ten-year period.
St. Louis County Parks prohibit drone operation in all parks except Buder Park and a portion of Antire Valley, where designated model-aviation areas operated by the Lafayette Esquadrille and the Greater St. Louis Modeling Association are allowed.
Commercial drone flight in Missouri is governed primarily by FAA Part 107, which preempts local airspace rules. Missouri adds surveillance and weaponization restrictions, while cities may only regulate ground-level operations on public property.
Missouri RSMo 305.637 prohibits using drones for warrantless surveillance, and RSMo 565.253 criminalizes voyeurism by drone. Federal FAA rules govern airspace and registration, leaving cities limited authority over operations.
Missouri Amendment 3 (2022) legalized adult-use cannabis. St. Louis County allows licensed dispensaries in commercial zones subject to local zoning review. Microbusiness licenses (Sept 2023+) are issued by the state; local zoning still applies.
Under Missouri Constitution Article XIV §2, registered patients and adults 21+ may cultivate up to 6 flowering and 6 non-flowering marijuana plants per registered consumer in a locked, enclosed indoor area. St. Louis County has not added stricter local rules.
Missouri Constitution Article XIV grants registered adults age 21 and over the right to cultivate up to six flowering plants at home with a $100 state registration. Localities cannot prohibit cultivation but may impose limited restrictions.
SLCRO §1005.095 recognizes subdivision trust indentures — private agreements between trustees and homeowners — as the primary tool for enforcing subdivision-level standards beyond county ordinances. Indenture violations are private civil matters, not county code enforcement.
Missouri has no general HOA statute, so ordinary homeowners' association liens come only from the recorded declaration. Condominiums are different: under the Missouri Uniform Condominium Act, § 448.3-116 gives the association a statutory lien for unpaid assessments and fines, with a six-month priority over a first mortgage, foreclosable like a mortgage.
Most Missouri HOAs are nonprofit corporations governed by the Nonprofit Corporation Law (Ch. 355): an annual members' meeting (§ 355.231), special meetings on a 5% member demand (§ 355.236), director removal at a noticed meeting (§ 355.346), and member record inspection on five business days' notice (§ 355.826). Condominium boards follow § 448.3-108 instead.
Missouri has no statute that caps HOA fines, sets a notice period, or requires a hearing before a non-condo association penalizes an owner — fine authority comes entirely from the recorded declaration and bylaws. For condominiums, § 448.3-116 lets the association collect fines through the same lien used for assessments.
Missouri's main statutory check on HOA authority is solar. Effective August 28, 2024, § 442.404 voids any covenant that limits or prohibits rooftop solar panels, allowing only reasonable placement rules. Section 442.012 makes the right to use solar energy a property right. Missouri has no general statute shielding flags or political signs from HOA bans.
Missouri RSMo 71.010 preempts local minimum wage ordinances, requiring cities and counties to follow only the state minimum wage and barring higher local wage floors approved by municipalities.
Missouri RSMo 71.010 also limits cities and counties from mandating paid leave or other employment benefits beyond state law, keeping benefit standards uniform across Missouri employers.
Missouri RSMo 71.010 preempts local predictive scheduling ordinances, preventing cities and counties from imposing fair workweek or advance-notice rules on private employers.
Missouri is a permitless concealed carry state and bars localities from imposing additional rules on concealed firearms beyond what RSMo 21.750 and Chapter 571 permit, ensuring uniform statewide carry standards.
Missouri broadly preempts local firearm regulation under RSMo 21.750, reserving most gun-related legislation to the state legislature and barring city or county ordinances on possession, transport, or registration.
Missouri permits open carry statewide, but RSMo 21.750 lets cities restrict open carry within their limits while exempting valid concealed carry permit holders from those local restrictions.
Missouri RSMo 571.030 allows adults 19 and older to carry concealed firearms in vehicles without a permit, and state preemption blocks cities from adding stricter local vehicle-carry rules.
Missouri RSMo 285.530 requires state contractors and public employers to enroll in E-Verify and bars employment of unauthorized aliens, creating a uniform statewide standard for verifying work authorization.
Missouri RSMo 67.307 forbids any municipality from adopting sanctuary policies, requiring local officials to cooperate with federal immigration authorities and barring restrictions on information-sharing about immigration status.
Missouri RSMo 537.295 and constitutional protections constrain how counties and cities may zone agriculture, limiting local authority to restrict expansions or modernization of established farms.
Missouri RSMo 537.295 shields established agricultural operations from most nuisance lawsuits, codifying a constitutional right to farm and limiting damages available against compliant farms and ranches.
Missouri RSMo 260.283, enacted in 2015, prohibits cities and counties from imposing bans, fees, or taxes on plastic bags and other auxiliary containers used by retailers and customers.
Missouri RSMo 260.283 also bars cities and counties from prohibiting or restricting polystyrene foam cups, plates, and food containers, treating them as protected auxiliary containers under state law.
Missouri RSMo 260.283 prevents cities and counties from banning plastic straws, utensils, and other single-use items, classifying them as protected auxiliary containers under state law.
Missouri raised its tobacco minimum sales age to 21 through RSMo 407.927, aligning state law with federal Tobacco 21 standards covering cigarettes, cigars, smokeless tobacco, and vapor products.
Missouri has no statewide ban on flavored tobacco or vapor products, and RSMo 407.927 governs sales standards while leaving questions about local flavor bans unresolved at the state level.
Missouri RSMo 407.927 governs the sale of tobacco, alternative nicotine, and vapor products, requiring age verification and aligning state retail standards with federal Tobacco 21 limits.
