Mill Valley, in short

Do I need a permit to remove a tree on my property in Mill Valley?

Sometimes. The City requires a permit for removal or major pruning of a Heritage tree, and to cut four or more other trees over 19 inches around on a developed lot in a year. A coast redwood is a Heritage tree at 95 inches around, about 30 across. Allow up to 30 days.

The story of Mill Valley

Mill Valley, named for John Reed’s sawmill, at the foot of Mount Tamalpais.

The Historic Context Statement traces Mill Valley from the Huimen group of the Coast Miwok, through two Mexican land grants and John Reed’s sawmill, to the 1890 land auction that started the town and the scenic railway that carried visitors up Mount Tamalpais. After the 1906 earthquake about half of the town’s households hosted refugees, and the 1936 City Hall, paid for by the Works Progress Administration, still stands.

The Historic Context Statement says the land that is now Mill Valley was occupied by the Huimen group of the Coast Miwok.

In 1834, the Statement says, John Reed was awarded Rancho Corte Madera del Presidio; the name meant “ranch of cut wood of the Presidio”, a grant provision that required Reed to provide cut wood for the Presidio of San Francisco. His sawmill later gave the town its name.

Present-day Mill Valley lies at the junction of that grant and Rancho Sausalito, granted to William Richardson in 1838.

In the 1850s Samuel Throckmorton turned Richardson’s ranch from cattle into dairy ranches, leased primarily by Portuguese immigrants from the Azores.

In 1873 Dr. John Cushing, a San Francisco physician, acquired 320 acres between the Reed and Richardson lands; after his death in 1879 his widow and son opened the first hotel in present-day Mill Valley.

The first train reached the new downtown station in 1889, and the station sign read both Eastland and Mill Valley.

In 1890, at a public land auction beside the old Reed mill, the Tamalpais Land & Water Company sold several hundred lots; the buyers, unsatisfied with the name Eastland, voted that year to change it to Mill Valley in remembrance of Reed’s mill and the area’s early association with the lumber industry.

By mid-June 1892, the Statement says, 150 campsites had been set up in Mill Valley, serving over 700 people.

In 1896 the Mill Valley & Mount Tamalpais Scenic Railway was incorporated; nicknamed “the Crookedest Railroad in the World”, it ran around 281 curves from downtown to the summit, until the last train in 1929.

Mill Valley was incorporated in 1900.

In 1902, 35 women signed the founding roll of the Outdoor Art Club, a local women’s civic club started in part as a response to redwood trees being cut. Its clubhouse was built in 1904.

After the 1906 earthquake, the Statement says, approximately half of Mill Valley households hosted refugees, either in their own home or by letting people camp on their land.

The Great Fire of 1929 began at the head of Blithedale Canyon and burned approximately 2,500 acres over three days; the Statement says 117 homes were destroyed or heavily damaged, the City’s history page says 110 were destroyed, and the Garden of Allah, now the Ralston White Retreat, was spared.

In 1936 the Works Progress Administration funded a new City Hall and Firehouse on Corte Madera Avenue, designed by local architect Walter C. Falch in Tudor Revival style.

The Golden Gate Bridge, completed in 1937, brought easy automobile access to and from San Francisco and a building upturn.

In the 1940s builder George Goheen put up 351 houses in a tract called Sycamore Village, colloquially “Goheen Gulch”; by 1950, the Statement says, one in ten people in Mill Valley is estimated to have lived in a Goheen-built house.

In 1947 Mill Valley officially became the “City of Mill Valley”.

The Mill Valley Air Force Station was built in 1950 at the top of Mount Tamalpais, and its radar dome is now “somewhat of a visual landmark”.

In 1956 Beat poet Gary Snyder moved into a cabin on Montford Avenue he named Marin-An, and invited writer Jack Kerouac to live with him during the summer.

On June 10 and 11, 1967, over 36,000 people filled the Cushing Memorial Amphitheater for the Magic Mountain Music Festival, which the Statement says is generally considered to be the first open-air rock festival.

A civic beautification project that repainted buildings in coordinated earth-tone colors won Mill Valley a national Distinguished Achievement award in 1968.

In 2021 the City Council adopted a Historic Context Statement and a Historic Resources Inventory Survey Report.

In 2025 the California State Historic Resources Commission approved the nomination of the 1936 City Hall and Fire Station #6 building for the California Historical Resources List.

Fire safety

Your fire department

Since July 1, 2023, the Southern Marin Fire Protection District has been the fire department of the City of Mill Valley. The City’s code says: “The Southern Marin Fire Protection District is hereby designated, and shall serve, as the Fire Department of the City of Mill Valley.”

The State’s map of Mill Valley

Read from the State Fire Marshal’s recommended map of local-area fire hazard severity zones, one of the 2025 maps the State released in four phases between February 10 and March 24, 2025, Mill Valley has Very High, High and Moderate zones inside the city. This is the State’s recommended map in its online layer, not the zones the City or the District adopted, and the reading names no neighborhood or address.

The City’s Safety Element on fire zones

The Safety Element says: “The residential communities located in the northern part of Mill Valley are mostly located in a Very High Fire Hazard Severity Zone (FHSZ) and High FHSZ”, and that some residences and downtown commercial areas lie within the Moderate FHSZ. Its cover is dated January 20, 2026. To see which zone your own address is in, the Fire District’s inspection page links a Fire Hazard Severity Zone Search Map.

Cover dated January 20, 2026

Where the interface areas are

The Safety Element says significant portions of the Mill Valley community are in a designated wildland-urban interface area, and names Warner Canyon, Mill Valley Ridge, Blithedale Canyon, Blithedale Ridge, Cascade Canyon, Fern Canyon, Summit Ridge, Scott Valley, and the southeast face of Mount Tamalpais.

The City’s clearing rule

The City’s fire code, section 15.04.050, applies to owners of buildings and of land “within specific Wildland-Urban Interface Areas”. It asks them to cut and remove all pyrophytic combustible vegetation and ground coverings within 10 feet of property lines and driveways and within 100 feet of structures, up to 200 feet (but not beyond the property line) when topography or the kinds of vegetation call for it, as the Fire Chief or the Chief’s designee determines. The code defines pyrophytic vegetation as vegetation that is highly flammable and endangers public safety by creating a fire hazard.

Ordinance 1364, adopted December 8, 2025

Leaves and needles on the roof and in the gutters

Among the duties the code lists for owners in those areas: “Clean any leaves and needles from roof and gutters.” The Fire District’s own fire code, which the City ratified, says the same in section 604.6. The code also asks owners to cut tree limbs that overhang wood decks and roofs, and to remove the part of any tree that extends within 10 feet of a chimney, stovepipe, roof surface or roof gutter.

Metal gutter covers, on the District’s list

The Fire District’s home-hardening page prints CAL FIRE’s list of low-cost ways to harden a home, which says: “Install noncombustible corrosion resistant metal gutter covers on gutters to prevent the accumulation of leaves and debris in the gutter.”

Ten plants to remove

Since May 1, 2021, the code has also asked owners in those areas to remove ten plants from the whole parcel: acacia, bamboo, arborvitae, Italian cypress, juniper, French, Portuguese, Scotch and Spanish broom, and gorse.

The first 3 feet

The City’s code says owners “are encouraged to voluntarily clear and create hardscape within the first 3 feet surrounding any residential or commercial structure”, and that a deck or patio is considered part of the structure.

Ordinance 1364, adopted December 8, 2025

Zone 0, the State’s rule

The State’s Zone 0 rule was adopted by the Board of Forestry; it is in final review with the Office of Administrative Law, and no effective date is known. This is the status on our standing check of October 22, 2026.

Standing check of Oct 22 2026

Inspections

The Fire District describes a defensible space inspection as “an annual review of a property, conducted by a fire official in the Wildland Urban Interface (WUI)”.

A 1996 vote and the City’s vegetation program

The Safety Element says a Municipal Services Tax approved by Mill Valley voters in 1996 allowed the creation of the City’s Vegetation Management Program, and that the program “removes 300 tons of fire fuel from Mill Valley every year”. The City’s own page for it now sends residents to the Fire District.

The City’s words on wildfire

The City’s wildfire page says “Wildfire is one of Mill Valley’s most significant risks.” Among its protective measures: “Trim tree branches at least 10 feet from your roof and chimney.” and “Move firewood, propane tanks, and other flammables at least 30 feet away from structures.”

Inspections of a re-roof

The City’s re-roofing handout says tear-off inspections are required for all residential roofs and “Final inspections are required for all reroofs”.

Historic houses

The City’s Survey Report says its Historic Overlay zoning, adopted in 1975, “requires design review of any addition or alteration to listed structures, in accordance with the Secretary of the Interior’s Standards for Rehabilitation”. The City’s code, section 20.54.030, says permits within a Historic Overlay district “shall be subject to Design Review” when they involve “exterior alterations”; it does not name re-roofing. If your house is listed, ask the City’s Planning Division whether your roof falls under it. Code read on ecode360 on November 5, 2026.

Survey Report adopted June 7, 2021

Heritage trees

A permit is required for removal or major pruning of Heritage trees. The City’s list, measured at four and a half feet above the ground: tanbark oak, 65 inches around (about 20 across); oak, 75 inches (about 24); madrone, 75 inches (about 24); coast redwood, 95 inches (about 30); and any tree the City Council designates by resolution.

Four or more trees

On a developed lot, a permit is required to cut four or more trees over 19 inches around (about 6 inches across) in a 12-month period, unless the City asks in writing for the removal for vegetative management. The Tree Removal page asks owners to allow up to 30 days for the process and approval.

Trees on a vacant lot

On a vacant lot, a permit is required to cut any tree over 12 and a half inches around (about 4 inches across).

Fire danger comes first

A tree removal permit may be granted when removal is necessary for any of five objectives; the first is “To protect the public health and safety by reducing or eliminating fire danger and other potential hazards to persons or property”. Removing trees under the fire code still follows the tree chapter, 20.67.

Trees on City property

For a tree on City property the City says “A permit is required to trim, brace, alter or remove any tree on city property”, and its handout sends you to the Public Works Department.

Roof water and the sewer

The City’s sewer chapter, section 17.04.320, says “it is unlawful to discharge into any sub-main or main sewer or house lateral any leader pipe from a roof, surface drain, underground drain”.

When you buy or sell The fire inspection before a sale

The Fire District’s inspection page describes the State’s sale rule (Civil Code 1102.19) this way: it “requires a seller of real estate property located in a High or Very High Fire Hazard Severity Zone to provide the buyer with documentation stating the property is in compliance with defensible space requirements”. Another Fire District page says “The designation of a Moderate, High, or Very High Severity Zone indicates that enhanced building requirements and re-sale inspections may be required for your parcel.” The two pages differ on a Moderate zone: if your home is in one, ask Fire Prevention.

Where it floods

The Safety Element says “the majority of the city’s flooding has occurred in the low-lying areas that are susceptible during sunny-day king tide events” and that “The Sycamore Avenue and Plymouth Street neighborhoods are the most impacted by these flooding events.” The City’s flood plan adds that when a rainfall peaks during a high tide, the impacts are worse.

Creeks and storm drains

The flood plan counts almost 16 miles of storm drain pipe in the City and names seven creeks draining through it. It says the two largest, Arroyo Corte Madera del Presidio and Warner Canyon Creek, “capture around 70% of runoff within the City boundaries”.

Building in a floodplain

The City’s floodplain page says a permit is required before any construction in a floodplain that FEMA designates AO, AE or Floodway. FEMA’s Community Status Book lists the City’s current effective flood map date as 08/15/17.

Landslides on the hillsides

The Safety Element says “Most of Mill Valley is susceptible to landslides due to the steep terrain throughout the city”, that the flat downtown between Miller Avenue and East Blithedale Avenue has little to no landslide susceptibility, and that mudslides “typically occur during heavy rainfall events”.

Wind and fallen trees

The Safety Element says the hilly and mountainous areas around the City “are more susceptible to damage from wind because of the greater presence of trees”, with downed trees hindering access on “the numerous windy and dead-end roads”.

The Board of Forestry’s brochure says “FRRCL communities may see a discount on insurance costs.” Whether your own policy shows one is the insurer’s call: ask your insurance company or agent.

The homes of Mill Valley

Mill Valley’s median home was built in 1958. About four in five homes were built in 1979 or earlier, about 70 percent are single-family houses that stand apart, and about two in three occupied homes are owner-occupied, our own calculations from the Census Bureau’s 2020-2024 tables.

1883 to 1899

Early wood-frame homes

1900 to 1929

First Bay Tradition, Craftsman and Tudor Revival

The First Bay Tradition (Shingle) style is “by far the most common” of the period, with redwood shingle siding and gable or gambrel roofs. Craftsman homes have front or side gable roofs with knee braces and exposed rafter tails, and Tudor Revival homes steeply pitched gable roofs with stucco and faux half-timber.

1930 to 1945

Gable and hip roofs, Spanish Colonial Revival and Minimal Traditional

1946 to 1980

Tract subdivisions

The Statement says one-story houses predominate, with some two-story split-levels, and that hip or gable roofs are most common. Its styles include California Ranch, Midcentury Modern with flat and low-pitched gable roofs, and Bay Tradition houses with flat, shed or sawtooth roofs.

Modernist experiments

History and character

The Historic Context Statement says the land that is now Mill Valley was occupied by the Huimen group of the Coast Miwok.

In 1834, the Statement says, John Reed was awarded Rancho Corte Madera del Presidio; the name meant “ranch of cut wood of the Presidio”, a grant provision that required Reed to provide cut wood for the Presidio of San Francisco. His sawmill later gave the town its name.

Present-day Mill Valley lies at the junction of that grant and Rancho Sausalito, granted to William Richardson in 1838.

In the 1850s Samuel Throckmorton turned Richardson’s ranch from cattle into dairy ranches, leased primarily by Portuguese immigrants from the Azores.

In 1873 Dr. John Cushing, a San Francisco physician, acquired 320 acres between the Reed and Richardson lands; after his death in 1879 his widow and son opened the first hotel in present-day Mill Valley.

The first train reached the new downtown station in 1889, and the station sign read both Eastland and Mill Valley.

In 1890, at a public land auction beside the old Reed mill, the Tamalpais Land & Water Company sold several hundred lots; the buyers, unsatisfied with the name Eastland, voted that year to change it to Mill Valley in remembrance of Reed’s mill and the area’s early association with the lumber industry.

By mid-June 1892, the Statement says, 150 campsites had been set up in Mill Valley, serving over 700 people.

In 1896 the Mill Valley & Mount Tamalpais Scenic Railway was incorporated; nicknamed “the Crookedest Railroad in the World”, it ran around 281 curves from downtown to the summit, until the last train in 1929.

Mill Valley was incorporated in 1900.

In 1902, 35 women signed the founding roll of the Outdoor Art Club, a local women’s civic club started in part as a response to redwood trees being cut. Its clubhouse was built in 1904.

After the 1906 earthquake, the Statement says, approximately half of Mill Valley households hosted refugees, either in their own home or by letting people camp on their land.

The Great Fire of 1929 began at the head of Blithedale Canyon and burned approximately 2,500 acres over three days; the Statement says 117 homes were destroyed or heavily damaged, the City’s history page says 110 were destroyed, and the Garden of Allah, now the Ralston White Retreat, was spared.

In 1936 the Works Progress Administration funded a new City Hall and Firehouse on Corte Madera Avenue, designed by local architect Walter C. Falch in Tudor Revival style.

The Golden Gate Bridge, completed in 1937, brought easy automobile access to and from San Francisco and a building upturn.

In the 1940s builder George Goheen put up 351 houses in a tract called Sycamore Village, colloquially “Goheen Gulch”; by 1950, the Statement says, one in ten people in Mill Valley is estimated to have lived in a Goheen-built house.

In 1947 Mill Valley officially became the “City of Mill Valley”.

The Mill Valley Air Force Station was built in 1950 at the top of Mount Tamalpais, and its radar dome is now “somewhat of a visual landmark”.

In 1956 Beat poet Gary Snyder moved into a cabin on Montford Avenue he named Marin-An, and invited writer Jack Kerouac to live with him during the summer.

On June 10 and 11, 1967, over 36,000 people filled the Cushing Memorial Amphitheater for the Magic Mountain Music Festival, which the Statement says is generally considered to be the first open-air rock festival.

A civic beautification project that repainted buildings in coordinated earth-tone colors won Mill Valley a national Distinguished Achievement award in 1968.

In 2021 the City Council adopted a Historic Context Statement and a Historic Resources Inventory Survey Report.

In 2025 the California State Historic Resources Commission approved the nomination of the 1936 City Hall and Fire Station #6 building for the California Historical Resources List.

Mill Valley, roof and gutters

Mill Valley has two kinds of ground. The City’s Safety Element says it lies in the California Coast Ranges with “steep hills and ridges, flat marshlands, bay plains, and mudflats”. In the canyons the City’s Land Use Element describes narrow, circuitous roads, with redwoods and broadleaf evergreens screening most homes from full view; the shops and denser housing sit on the flat low lands.

Yearly rain is about 36 to 44 inches, by the NOAA 1991-2020 normals of the two nearest federal stations, Muir Woods (36.24 inches, 1.3 miles from City Hall) and Kentfield (44.39 inches, 3.4 miles), our own calculation. October to April carry about 95 percent of the year’s rain, and July is the driest month.

The trees decide what lands on a roof here. The City’s Natural Environment Element names coast redwood, Douglas fir, bay laurel, Pacific madrone and bigleaf maple among the native trees of the Mill Valley canopy, and coast live oak among its oaks. The University of California Marin Master Gardeners say of coast redwoods: “Needles clog gutters and increase fire risk.” The Forest Service says coast live oak’s leaves emerge from February to April and the old leaves are shed at the same time.

We have been working on Bay Area roofs and gutters since 2002. If yours hasn’t had a look in a while, we’d be glad to come by.

Mill Valley questions

What Mill Valley homeowners ask us

Do I need a permit to replace my roof in Mill Valley?

To replace it, yes: the City lists “Re-Roof” among the minor permits it issues automatically to licensed contractors upon application, with the permit card mailed after an administrative review, generally within a week. The City requires inspections, and its handout says “Final inspections are required for all reroofs”. The City also asks every applicant to “confirm the job site address is located in the City of Mill Valley and NOT in an Unincorporated area of Mill Valley”. If you wish, we can also pull the permit for you, as most of our customers ask us to.

Do I have to keep my roof and gutters clear of leaves and needles in Mill Valley?

In the City’s wildland-urban interface areas, yes. The City’s code applies to owners of buildings and of land “within specific Wildland-Urban Interface Areas” and lists: “Clean any leaves and needles from roof and gutters.” The Fire District’s own fire code, which the City ratified, says the same. To check your address, the Fire District’s WUI Properties page sends you to a County map.

Where may I send my downspouts in Mill Valley?

Not into the sewer. The City’s sewer chapter says “it is unlawful to discharge into any sub-main or main sewer or house lateral any leader pipe from a roof, surface drain, underground drain”, and the City’s sewer lateral inspection report names “downspouts or outdoor drain connections” among the faults that keep a lateral from passing.

Downtown
The City’s Land Use Element describes downtown as “a tight configuration of one- and two-story buildings clustered around Lytton Square and the Depot Plaza.”

Cascade and Blithedale Canyons
The Land Use Element heads one character area “Cascade and Blithedale Canyons” and describes narrow, circuitous roads, redwoods and broadleaf evergreens that screen most homes from full view, and the sense of containment of the canyon walls.

Warner Canyon and Kite Hill
The Land Use Element’s “Warner Canyon/Kite Hill” area holds two distinctive character areas; along the ridgelines, lot sizes are as large as ten acres or more.

Miller/Molino
The Land Use Element says the hillside roads in the Miller/Molino area are narrow and circuitous, and that homes on its northeast-facing slopes have broad views out over the central portion of Mill Valley.

Sycamore and Tamalpais Park
“The relatively level topography and more conventional lotting pattern of the Sycamore/ Tamalpais Park neighborhood creates a design character quite different from the hillside and canyon areas of Mill Valley,” the Land Use Element says. The Historic Context Statement says lots in Tamalpais Park were first sold in 1906 and the early homes tended to be First Bay Tradition or stucco-clad bungalows.

Scott Valley
One of the areas the Safety Element names in the wildland-urban interface; the City’s directory lists a Scott Valley Homeowners’ Association.

Enchanted Knolls
The Historic Context Statement lists it among the postwar tract neighborhoods: “Concentrated in neighborhoods such as Enchanted Knolls, Scott Valley, Scott Highlands, Kite Hill, and Shelter Ridge.”

Old Mill
The City’s directory lists an Old Mill Neighborhood Association, and the Historic Context Statement says the Old Mill School, now Old Mill Elementary School, was built in 1921.

Miller Avenue
The Land Use Element says “East Blithedale Avenue, Miller Avenue, and Camino Alto are the community’s primary arterial roadways” and that “Lower Miller Avenue, from Locust Street to Camino Alto, functions as the full-service commercial area for the community.”

Also covering Tam Valley, Homestead Valley, Almonte, Alto and Strawberry
The Fire District serves these communities next door along with Mill Valley, and the City’s sandbag list includes sites in Strawberry and Tam Valley. The Historic Context Statement says that in 1948 Alto, Almonte, Homestead Valley, Tamalpais Valley and Marin Heights were given Mill Valley addresses so they could receive mail service from the Mill Valley Post Office.
