The City of Westminster's own Noise Control ordinance (WMC Chapter 8.28) does not use blanket 'quiet hours' but sets day/night exterior sound-level limits. Citywide (Zone 1) the limit is 55 dB(A) day and night; in R2-R5 multifamily districts (Zone 2) it drops from 60 dB(A) daytime to 55 dB(A) between 10 p.m. and 7 a.m.

Under the City of Westminster's own code (WMC Section 8.28.060(E)), construction, repair, remodeling and grading noise is exempt from the noise limits only if it does NOT occur between 8 p.m. and 7 a.m. on weekdays including Saturday, and not at all on Sundays or federal holidays.

The City of Westminster has a specific barking-dog law (WMC 6.08.180, added by Ord. 2553, 2018). A 'barking dog' (defined in WMC 6.04.020) that barks, bays, howls or cries audibly across property lines for 30 minutes or more incessantly, or intermittently, in any 24-hour period is declared a public nuisance.

The City of Westminster limits residential leaf-blower use to 8:00 a.m.-5:00 p.m. Monday through Saturday. On Sundays and holidays only the resident may use one, 9:00 a.m.-5:00 p.m. Just one leaf blower per address may run at a time, capped at fifteen minutes per day, per the city's published code-enforcement standards.

Westminster has no separate amplified-sound permit chapter; amplified music is controlled by the dB(A) limits in WMC Chapter 8.28. Because amplified music counts as 'music' content, the applicable limit is lowered by 5 dB(A) - so as low as 50 dB(A) in citywide Zone 1 - making sustained amplified music a likely public-nuisance violation.

Westminster's noise chapter does not separately regulate vehicle exhaust; on-road vehicle noise is controlled by California state law. CA Vehicle Code 27150 requires an adequate muffler with no cutout or bypass, and 27151 bans exhaust modifications that amplify noise - generally over a 95 dBA test threshold for lighter passenger vehicles.

Westminster's own code sets numeric dB(A) noise limits in WMC 8.28.040 (exterior) and 8.28.050 (interior). Citywide Zone 1 exterior is 55 dB(A) day and night; R2-R5 Zone 2 is 60 dB(A) day and 55 dB(A) at night. Music, speech, tone and impact noise are measured 5 dB(A) lower.

Outdoor music in Westminster is governed by the general dB(A) limits of WMC Chapter 8.28, with a 5 dB(A) reduction because the noise contains music. Permitted public outdoor gatherings and events are exempt under WMC 8.28.060(B); unpermitted backyard or commercial outdoor music must meet the standard limits.

Industrial and commercial noise in Westminster is governed by the property-line dB(A) limits of WMC Chapter 8.28. Citywide Zone 1 is 55 dB(A) day and night; the higher Zone 2 limits apply only in R2-R5 residential districts. Steady industrial noise containing tones is measured 5 dB(A) lower, and graduated duration triggers apply.

Westminster cannot locally regulate aircraft noise. Aviation noise is preempted by federal law (the FAA), and WMC 8.28.060(J) itself exempts activities preempted by state or federal law. Complaints about overflights, helicopters or jets go to the FAA, not the city. The city's dB(A) limits do not apply to aircraft in flight.

The City of Westminster does not issue short-term rental permits. Chapter 9.74 of the Municipal Code affirmatively prohibits renting any residential dwelling for transient use of 30 days or less in residential and mixed-use zones, so there is no permit, license, or registration pathway for a residential STR.

Westminster has no STR registration system because short-term rentals are banned. There is no city registry, application, or certificate for renting a home for 30 days or less; Chapter 9.74 prohibits the use outright rather than registering it.

Westminster levies an 8% Transient Occupancy Tax on lawful lodging, but residential short-term rentals are banned, so there are no STR permit fees and no TOT path for homes. The 8% bed tax applies to hotels and motels, not to prohibited residential STRs.

Westminster sets no STR guest-occupancy limit because residential short-term rentals are banned outright. Chapter 9.74 prohibits transient use of homes for 30 days or less, so there is no permitted occupancy figure - the lawful number of STR guests is zero.

Westminster has no STR-specific parking standard because short-term rentals are banned. Chapter 9.74 prohibits transient rental of homes for 30 days or less, so there are no off-street parking requirements tied to a permitted STR - the use is not allowed in the first place.

Westminster sets no STR-specific noise standard because short-term rentals are banned under Chapter 9.74. The city's general noise and nuisance ordinances still apply to all residents, but there is no permitted STR for which special quiet-hour conditions could exist.

Westminster has no primary-residence STR allowance because all residential short-term rentals are banned. Chapter 9.74 prohibits transient use of 30 days or less whether the home is owner-occupied or not - there is no homeowner exception.

Westminster imposes no host-presence requirement because short-term rentals are banned entirely. Chapter 9.74 prohibits transient rental of homes for 30 days or less whether the host is present or absent - there is no 'hosted' STR category.

Westminster sets no annual night cap because short-term rentals are banned, not rationed. Chapter 9.74 prohibits any rental of a residential dwelling for 30 days or less, so the effective limit on STR nights is zero rather than a capped number of nights per year.

Westminster imposes no STR insurance requirement because short-term rentals are banned. Chapter 9.74 prohibits transient rental of homes for 30 days or less, so there is no permit through which a liability-insurance or indemnification condition could be required.

Unlike many California cities, Westminster permits state-approved "Safe and Sane" fireworks bearing the State Fire Marshal seal. Sales run June 30 through July 4 from licensed stands, and discharge is limited to July 4th. All aerial and exploding fireworks are illegal, carrying a $1,000 fine.

Westminster has no standalone fire-pit ordinance. Recreational fire pits are governed by the California Fire Code (adopted in WMC Chapter 15.22 and enforced by the Orange County Fire Authority) and South Coast AQMD air-quality rules. Use approved devices, keep clearances, and never let smoke create a nuisance.

Open outdoor burning of trash, leaves, and yard waste is effectively prohibited in Westminster. The South Coast AQMD bans residential open burning across this urban air basin, and the Orange County Fire Authority enforces California Fire Code burn limits. Use trash and green-waste collection instead.

Westminster is a flat, fully developed urban city with no wildland interface, so it has no defensible-space brush-clearance program. Overgrown, dead, or dry vegetation is instead handled as a public nuisance under Municipal Code Chapter 8.20, which the city can abate and lien.

Smoke and carbon monoxide alarm requirements in Westminster come from California state law, not a special city ordinance. State law mandates smoke alarms in every bedroom, outside sleeping areas, and on each level, plus CO alarms in dwellings with fuel-burning appliances or attached garages.

Westminster has no ordinance banning recreational backyard fires, but burning trash or yard waste is prohibited. Recreational fires in approved pits or fireplaces must follow the California Fire Code (enforced by OCFA) and South Coast AQMD no-burn rules, and must not create a smoke nuisance for neighbors.

Westminster relies on the California Fire Code for propane (LP-gas) storage, adopted in Municipal Code Chapter 15.22 and enforced by the Orange County Fire Authority. Household barbecue and patio cylinders are allowed within state limits, while larger quantities and multifamily settings face tighter restrictions and may require permits.

Westminster is a flat, fully built-out coastal-plain city with no wildland interface, so it is not mapped as a Very High Fire Hazard Severity Zone. Wildfire risk is minimal, and the defensible-space rules that apply in Orange County's canyon and foothill communities do not apply here.

Westminster prohibits parking any recreational vehicle on a city street without a valid RV permit from the Police Department. Effective January 1, 2025, residents may obtain up to twelve non-consecutive 24-hour permits per year, solely to load, unload, clean, or maintain before and after travel.

Westminster regulates curbside parking through its Municipal Code, prohibiting parking longer than 72 consecutive hours, restricting large vehicles, and enforcing street-sweeping schedules. Curb colors and posted signs control where and when you may park, on top of California Vehicle Code rules.

Westminster has no blanket overnight parking ban on standard passenger cars, but the 72-hour limit, street-sweeping windows, RV permit rules, and large-vehicle restrictions all apply at night. Posted signs and curb colors govern specific blocks, layered on top of California Vehicle Code rules.

Westminster Police mark suspected abandoned vehicles and tow them if they are not moved within 72 hours. The Municipal Code prohibits parking or storing any vehicle on a street for more than 72 consecutive hours and bans storing inoperable or junk vehicles in public view.

Westminster bans large vehicles on all city streets, prohibiting any vehicle wider than 84 inches, longer than 22 feet, or heavier than 10,000 pounds. The city's code enforcement also treats oversized commercial vehicles as incompatible with residential neighborhoods.

Westminster requires vehicles to be parked on paved driveways, streets, or in garages, and declares it a public nuisance to store or park vehicles on the unpaved open space of a residential front yard. Vehicles may not obstruct the public sidewalk, street, or alley.

Westminster bans oversized vehicles on every city street. Westminster Municipal Code Section 10.44.250 prohibits any vehicle wider than 84 inches, longer than 22 feet, or heavier than 10,000 pounds, capturing large trucks, buses, big trailers, and many RVs.

Westminster has no city-specific ordinance reserving on-street EV charging spaces or ticketing non-charging vehicles. EV charging parking is governed by California Vehicle Code Section 22511 statewide, while the city offers a streamlined building permit process for installing chargers.

Westminster establishes loading zones with painted curbs under Municipal Code Chapter 10.48. Yellow curbs allow commercial loading of materials for up to 20 minutes, white curbs are for passenger loading only, and no more than half of a block's curb may be a loading zone.

Westminster Municipal Code Chapter 10.48 defines the meaning of painted curb colors. Red means no stopping at any time, yellow is a 7 a.m. to 6 p.m. loading zone, white is for passenger loading only, and green limits parking to 24 minutes between 9 a.m. and 6 p.m.

The City of Westminster's zoning code (WMC 17.300.030, Table 3-2) generally caps fences, walls and hedges at six feet, but limits them to three feet within a required front-yard or street-side-yard setback. Corner-lot fences are further restricted where they obstruct traffic visibility.

Westminster fences must meet the zoning standards in WMC 17.300.030 regardless of permit status. California's Building Code (CBC 105.2) exempts most fences up to seven feet from a building permit, but taller fences, retaining walls over four feet, and any work in a setback or visibility area trigger city review.

Westminster's zoning code (WMC 17.300.030) controls how tall and what type a boundary fence may be, including how height is measured between properties at different grades. Cost-sharing for a shared fence is governed by California's statewide Good Neighbor Fence Law, Civil Code 841, not by a Westminster ordinance.

Westminster's zoning code (WMC 17.300.030) controls how the height of a wall is measured between properties and within five feet of a right-of-way. Whether a building permit is required for a retaining wall follows California's statewide rule: masonry/concrete walls over four feet (from footing) need a permit under CBC 105.2.

Westminster Municipal Code 17.300.030 requires fences, walls and hedges to be installed and maintained per the city's standards, including the Table 3-2 height limits and corner traffic-visibility rules. Separate state rules (CBC) require self-latching barriers around swimming pools.

Westminster Municipal Code 17.300.030 prohibits fences that incorporate electrical currents, concertina ribbon, razor wire or ribbon, and pointed, protruding or sharp objects, except as allowed by WMC 17.300.035.H. Barbed wire is prohibited in the R1 through R5 residential zones between or adjacent to properties and walkways.

Westminster allows common fence materials — wood, vinyl, masonry, chain-link, and decorative wrought iron — subject to the height and visibility rules of WMC 17.300.030. Hazardous materials such as electrified wire, razor/concertina wire, and barbed wire (in R1–R5) are banned, while wrought-iron decorative tips are expressly permitted.

In the City of Westminster, dogs on public property must be restrained by a substantial chain or leash no longer than six feet, held by a competent person. Off-leash use is allowed only where the property owner or operator gives written permission. The rule is in the city's own Municipal Code, Title 6 (Animals).

Westminster's Municipal Code (Chapter 6.12) makes it generally unlawful to keep fowl, livestock or other non-household animals on any property in the city unless a permit is obtained from Westminster Animal Control. Keeping chickens is not an automatic backyard right here, and a permit is required first.

Westminster does not ban dogs by breed. Instead, its Municipal Code (Chapter 6.10) and California Food & Agricultural Code govern individual dogs declared potentially dangerous or vicious through a hearing. Declared dogs face leash, containment, insurance and signage requirements regardless of breed.

Westminster's Municipal Code (Chapter 6.12) lists bees among the animals it is unlawful to keep on any property in the city without a permit from Westminster Animal Control. Beekeeping is not an automatic backyard right here; state apiary registration with the county also applies.

Westminster's Municipal Code (Chapter 6.12) makes it unlawful to keep livestock anywhere in the city without a permit from Westminster Animal Control. As a dense urban Orange County city, horses, cattle, sheep, goats and swine are effectively prohibited on standard residential lots.

Westminster's Municipal Code (Chapter 6.12) makes it unlawful to keep any wild animal in the city. It lists specific small pets that are allowed, such as hamsters and non-venomous reptiles, and requires a permit for anything otherwise prohibited. California Fish & Game restricted-species law also applies.

Westminster Municipal Code Section 6.12.020 allows up to three dogs and/or three cats over four months old per household, not exceeding six animals total. Keeping more requires an animal maintenance permit from the Police Department. This is the city's own rule, separate from Orange County.

Westminster allows up to three cats over four months old per household under Municipal Code Section 6.12.020, within an overall six-animal cap. The city does not impose a cat leash law, and Westminster Animal Control handles stray and feral cats. California does not require cat licensing statewide.

Westminster's Municipal Code (Chapter 6.12) bans keeping wild animals and requires permits for prohibited animals, and the city addresses nuisance feeding through its animal-control and nuisance authority. California law also makes it illegal to feed big-game wildlife such as deer, bears and coyotes.

Westminster controls animal hoarding through its household pet-limit rule (Municipal Code Section 6.12.020) and its animal-cruelty and neglect enforcement by Westminster Animal Control. Exceeding three dogs, three cats or six animals total without a permit is the threshold that triggers enforcement.

The City of Westminster's Municipal Code does not set a numeric grass-height limit. Instead, Chapter 8.20 (Nuisances) declares overgrown, dead, decayed, or diseased weeds, grass, and vegetation a public nuisance when it harbors pests or threatens public health. Code Enforcement abates uncorrected nuisances and can lien the property.

Trees in the parkway between the sidewalk and curb are City trees. The City trims them on a predetermined schedule, while the adjacent homeowner is responsible only for watering. Under Westminster's Street Forestry Policy (Chapter 12.12), no one may cut, trim, prune, or otherwise interfere with a street tree without a permit from the Public Works Director.

Parkway and street trees are City property; residents may not remove them. Under Westminster's Street Forestry Policy (Chapter 12.12), no person may remove a street tree without a permit from the Public Works Director. The City handles removal and replacement of street trees, including those damaging public infrastructure.

Westminster Municipal Code Chapter 8.20 (Nuisances) declares overgrown, dead, decayed, or diseased weeds, grass, and vegetation a public nuisance when it harbors pests or threatens public health. Section 8.20.030 lists the prohibited conditions. The City gives notice and a hearing, then may abate and lien the property.

Westminster has year-round water rules in Municipal Code Chapter 13.14, aligned with state regulations. Landscape watering days are capped by the City's posted schedule, and limits tighten under declared shortage levels (Level 1 = 4 days/week; Nov 1-Mar 31 = 2 days/week; Level 3 = 1 day/week). Runoff and leaks are restricted.

Westminster does not prohibit residential rainwater harvesting; California law (AB 1750) broadly allows rooftop rain capture. The City promotes water conservation through MWDOC rebates, drought-tolerant Conservation Gardens, and free water-use audits, but the city pages reviewed describe no specific city rain-barrel mandate.

Westminster encourages native and drought-tolerant landscaping. New and rehabilitated landscapes subject to the City's Water Efficiency Landscape Measures (Chapter 17.310) must follow the state-based MWELO and the City's Handbook, favoring efficient irrigation and an appropriate plant mix. The City's Conservation Gardens model California-friendly and native plants.

Westminster expressly allows artificial turf under Artificial Turf Design Standards in Municipal Code Section 17.310.035, applicable to all zoning districts and uses. Only cut-pile, in-filled turf (nylon, polyethylene, or polypropylene) with an 8-to-12-year minimum no-fade warranty is permitted. Indoor/outdoor plastic or nylon carpeting is prohibited.

Under California SB 1383, Westminster requires residents and businesses to separate organic waste (food scraps, yard and pruning waste, food-soiled paper) for collection, not landfill. The City's franchised hauler provides organics (green-cart) service. Westminster also offers free locally sourced compost giveaways with Orange County.

Westminster allows home-based businesses in residential dwellings only as a use that is incidental and secondary to living in the home. The business must conform to the standards in Municipal Code section 17.400.075 and obtain a home-based business zoning clearance permit. Activities that disrupt the residential character of the neighborhood are not permitted.

Westminster prohibits on-site signage and advertising for home-based businesses, including signs on vehicles. Advertisements in any media — including the Internet and telephone directories — may not give the home's street address, and no advertising intended to attract customers to the dwelling is allowed. These rules are part of the operational standards in Municipal Code section 17.400.075.

Westminster requires a home-based business zoning clearance permit before a business license will be issued for a business in a residential dwelling. Applications go to the Planning Division on its form, must include written permission of the property owner or manager, and may be denied, approved, or conditionally approved within 10 days of a complete application.

Cottage food operations in Westminster are governed primarily by California's Homemade Food Act. Westminster's home-business code acknowledges cottage food and microenterprise home kitchen operations, and state law bars cities from banning them in residential dwellings. The City must permit them as a residential use, subject only to reasonable local conditions, while county environmental health handles food permitting.

Family day care homes in Westminster follow state law and Municipal Code section 17.400.035. Small family day care homes are allowed as a residential use, while a large family day care home requires an Administrative Use Permit and must meet City standards for play area, rear-yard open space, parking, and state licensing — all consistent with what California law lets cities require.

The City of Westminster Building Division requires a building permit to construct a swimming pool or spa. Standard plans built to City standards can often be checked over the counter and the permit issued the same day. Pool barrier and electrical/plumbing work is reviewed under the codes adopted in Title 15 of the Municipal Code.

Westminster requires pools and spas to be fenced and secured with approved materials. The barrier standards come from the California Swimming Pool Safety Act, adopted through the City's building codes: new pools at single-family homes must include at least two approved drowning-prevention features, including an enclosure at least 60 inches high with a self-closing, self-latching gate.

Westminster requires pools and spas to be kept clean, safe, and sanitary, and enforces the California Swimming Pool Safety Act through its adopted building codes. New residential pools must include at least two approved drowning-prevention features chosen from a state list of seven, such as a compliant barrier, alarms, or an approved safety cover.

Westminster's accessory-structure ordinance treats above-ground pools differently from in-ground pools. Municipal Code section 17.400.130 states that spas (in-ground or above ground) and above-ground pools are not considered "swimming pools" for that section's setback rules. A building permit may still be required, and the state Pool Safety Act and barrier rules still apply to qualifying pools.

Westminster requires a building permit for spas and treats spas (in-ground or above ground) as not "swimming pools" under accessory-structure section 17.400.130. Spas must be fenced/secured and kept clean and sanitary. The state Swimming Pool Safety Act barrier rules apply to spas that are not protected by an approved locking safety cover.

Westminster regulates accessory dwelling units under Permanent Ordinance No. 2572 (adopted March 24, 2021) and Zoning Code Section 17.400.135. ADUs are approved ministerially (no discretionary hearing) on a combined Planning Zoning Clearance and Building plan check, consistent with California state ADU law.

Westminster regulates detached accessory structures, including sheds, under Zoning Code Section 17.400.130. Small sheds 120 square feet or less and 7 feet or less in height are exempt from zoning development restrictions (though Building and Fire codes still apply) if placed behind the dwelling's front building line and inside required setbacks.

Westminster allows converting an existing garage or accessory structure into an accessory dwelling unit under Zoning Code Section 17.400.135 and Ordinance No. 2572. The city's ADU page lists garage conversion as a recognized way to create an ADU. Converting a garage to non-ADU living space without permits is prohibited.

In Westminster, carports may be permitted in the R1 single-family zone only in addition to the minimum number of enclosed garage spaces required by the Zoning Code. Required residential parking must be located in garages, carports, or approved parking areas under Chapter 17.320 (Off-Street Parking and Loading).

Westminster's Municipal Code has no separate "tiny home" category. Living in accessory structures is prohibited, and recreational vehicles or trailers may not be used as living quarters except in an approved mobile home park. A movable or fixed tiny house used as a residence must instead qualify as an accessory dwelling unit under Section 17.400.135.

Backyard barbecuing is unrestricted at single-family homes in Westminster. The key limits come from the California Fire Code (enforced by OCFA), which bars charcoal and open-flame grills on combustible apartment balconies and within 10 feet of combustible construction unless the building is sprinklered.

Westminster has no ordinance specific to barbecue smokers. They follow the same California Fire Code rules as other open-flame cooking devices—freely used at single-family homes, but restricted on combustible apartment balconies—and must not create a persistent smoke nuisance for neighbors.

Westminster regulates political signs in Zoning Code Section 17.330.025. Political signs must be on private property with the owner's permission, kept at least 5 feet from any public right-of-way, and may not exceed 40 square feet. They require no city permit but must be removed within 30 days after the election.

Westminster requires a garage sale permit (about $10) under Municipal Code Section 17.540.045. Garage sales are limited to 3 consecutive days, up to 3 times per residence per year (no more than one permit per residence in a 3-month period). Signs may not be placed on any public property and must be removed each day.

The City of Westminster enforces property-maintenance standards under Municipal Code Chapter 8.20 (Nuisances). Owners must keep property free of rubbish, overgrown vegetation, junk, and debris. Fences must stay upright and in good repair, and at least 50% of front yards must be landscaped with foliage.

Westminster requires trash and recycling carts to be screened from public view except on collection day. Cans may be set out only the evening before or on pickup day, and the city's code requires containers be stored so they are not visible from any highway on other than scheduled collection days.

Vacant and undeveloped lots in Westminster are subject to the same nuisance rules as occupied property under Municipal Code Chapter 8.20. Owners must keep lots free of weeds over 12 inches, rubbish, junk, debris and illegal dumping, or the city may abate the nuisance and lien the property.

Westminster Municipal Code Chapter 8.20 defines weeds as vegetation grown to a height over 12 inches and treats overgrown, dead or rank growth that can harbor pests as a public nuisance. Owners must keep property free of overgrown vegetation and weeds, or face abatement and a lien.

The City of Westminster regulates garage and yard sales under Municipal Code Section 17.540.045. Residents must obtain a garage sale permit before holding a sale, and sales are limited to three per residence per calendar year, with each sale lasting up to three days.

Westminster has no comprehensive dark-sky lighting ordinance. The City's Zoning Code addresses outdoor lighting through site-planning and development standards (Article 3 / Chapter 17.300 area), and statewide California Title 24 (Building Energy Efficiency Standards) governs outdoor lighting controls and shielding for new construction.

Westminster has no dedicated light-trespass ordinance with numeric foot-candle limits. Spillover and glare onto neighboring residential property are addressed through the Zoning Code's site-planning standards (which require lighting be shielded so it does not adversely affect adjacent residential uses) and the City's general nuisance provisions in Chapter 8.20.

Residential trash, recycling and organics in Westminster are collected weekly by the Midway City Sanitary District (MCSD), using CR&R-operated automated trucks. Each home gets blue, green and black carts. Set carts out by 7 a.m. on your service day or the night before. Holiday weeks shift collection one day later.

For automated collection, Westminster's Midway City Sanitary District requires carts to be placed in the gutter with wheels against the curb, spaced about three feet apart and three feet from any vehicle, pole or other obstruction. Lids must close, and carts must be removed within 12 hours after collection.

Westminster's Midway City Sanitary District offers a bulky-item pickup for furniture and appliances, with a maximum of two items every 30 days per household. Residents must schedule at least one week in advance and may not place items at the curb until a pickup is scheduled.

Westminster residents recycle through the blue cart collected by the Midway City Sanitary District. Businesses generating 4+ cubic yards of waste weekly and multifamily properties with 5+ units must arrange recycling under California's Mandatory Commercial Recycling law (AB 341), served by the city's franchise hauler CR&R.

Under California's SB 1383, organics recycling is mandatory in Westminster. The Midway City Sanitary District provides green carts (65 or 95 gallon) to single-family homes for food scraps and yard waste, collected weekly. Businesses and large multifamily properties must also recycle organics under AB 1826 (the city's MORe program).

Westminster regulates conduct in public parks under Municipal Code Chapter 12.24. City parks adjacent to arterial highways are closed to the public between 9:00 p.m. and 6:00 a.m., except during activities supervised by the Recreation and Parks Director. A separate minors' curfew (Chapter 9.70) bars under-18s from parks 10 p.m. to 6 a.m.

Westminster's zoning code sets required yards by zone in Table 2-3 (WMC 17.210.015), with general measurement and encroachment rules in WMC 17.300.020. In the single-family R1 zone the front-yard setback is 20 feet and the minimum side setback is 5 feet; setbacks vary across the R1–R5 zones.

Westminster sets maximum building heights by zone in Table 2-3 (WMC 17.210.015), with measurement and exceptions in WMC 17.300.025. Fences and walls are limited separately under WMC 17.300.030 (generally 6 feet). Exact residential height figures vary by zone and should be confirmed with the Planning Division.

Westminster regulates how much of a lot may be built upon through the development standards in Table 2-3 (WMC 17.210.015) and the front-yard landscaping requirements in WMC 17.310. The R1 zone caps density at seven units per acre and requires minimum front-yard landscaping; exact coverage percentages vary by zone.

Westminster's tree-removal permitting centers on City street and parkway trees. Under the Street Forestry Policy (Municipal Code Chapter 12.12), no person may remove or interfere with a street tree without a permit from the Public Works Director, who controls planting and removal in the public right-of-way (Section 12.12.060).
