The Corridor West
What Building in the Conejo Valley Actually Involves
The Conejo Valley runs west from the end of the San Fernando Valley, wrapping the northern edge of the Santa Monica Mountains and crossing from Los Angeles County into Ventura County. It behaves as one landscape — hot, dry, hilly, fire-exposed — while being governed by several different authorities.
Calabasas, Hidden Hills, Agoura Hills and the City of Westlake Village each permit through their own departments on the LA side, Thousand Oaks covers the Ventura side, and a large share of properties sit within HOAs with architectural review of their own. The first thing we establish on any Conejo project is which authorities govern the parcel — often two at once.

Conejo Valley Communities We Build In
We work across the Conejo corridor on both the Los Angeles and Ventura county sides. Each community below has its own page covering the conditions specific to it — slope, fire-zone status, HOA governance and the authority that permits the work.

Designing for a Corridor That Has Burned
The 2018 Woolsey Fire moved through this corridor and changed how people here build outdoors. Most of the Conejo Valley carries a Very High Fire Hazard Severity Zone designation, and that is the starting condition rather than an edge case.
We design around defensible-space zones as standard:
0–5 feet from the structure
Zone 0: Non-Combustible
The band against the house is built from stone, porcelain, concrete and gravel with planting kept out of it. California has been phasing in an ember-resistant zone requirement for these first few feet, so current rules are worth confirming with the governing city before design is finalised.
5–30 feet
Zone 1: Outdoor Living as Buffer
Patios, pools, shade structures and widely spaced low-resin planting sit here. Hardscape doubles as a fuel break, which is why the most usable part of a Conejo garden is also the most protective part.
30–100 feet
Zone 2: Structured Outer Landscape
On the larger parcels running toward open space we thin, limb and space planting so fire stays low rather than climbing into canopy and reaching the structure.
Designed properly the result reads as a finished landscape, not a firebreak.

Slope, Heat & Water
The Other Three Constraints
Beyond fire, three conditions shape nearly every Conejo project. Slope: most parcels carry real grade, and engineered terracing is what creates usable flat ground. Heat: summer afternoons here run hot and dry with intense sun, so a west-facing yard without shade goes unused for a third of the year. Water: watering runs under day-of-week limits set by each retailer, and evaporation inland is high.
The practical consequence is that shade structures and engineered walls do more for a Conejo property than any material upgrade, and planting should be chosen for a dry summer rather than fought through one. Storms here arrive as short intense events, so drainage is designed for the heaviest hour rather than the annual average.

Three Things We Establish First
The Conejo rewards knowing which rules apply before anything is drawn.
Which Authority — and Which County
Calabasas, Hidden Hills, Agoura Hills and the City of Westlake Village each permit through their own departments; the Ventura County side falls under Thousand Oaks. Westlake Village straddles the line, so the postal city does not reliably tell you which applies. We confirm for the specific address.
HOA Architectural Review
A large share of properties sit in planned communities whose committees review material, colour, fencing and structures on their own timeline. City approval does not substitute for it, and we prepare both submissions in parallel.
Fire Zone Status
Material restrictions for structures and decking, defensible space zoning and the ember-resistant band are settled at design stage and verified with the local fire authority for the parcel.
What We Build
Services Across the Conejo Valley
We handle landscape, hardscape, structures, pools and drainage as one accountable scope. On sloped fire-zone ground the engineering and compliance come first, and the design follows them rather than the other way around.
Retaining Walls and Terracing
Engineered walls that create level ground, with drainage designed before the wall rather than added to it.
Shade Structures
Patio covers and pergolas specified to satisfy fire-zone material rules and HOA review at once — the highest-return build on a hot exposed lot.
Backyard remodeling in Los Angeles →Pools and Spas
New construction and remodels, on flat planned-community lots and on sloped parcels needing engineered support.
Fire-Wise Landscaping
Defensible space zoning and ember-resistant detailing designed to read as a garden.
Driveway installation →Hardscape and Outdoor Kitchens
Terraces in stone, porcelain and paver, plus outdoor kitchens in noncombustible construction.
Water-Wise Planting
Species specified for inland heat and watering restrictions rather than from a catalogue.

See Your New Landscape Before It's Built
We begin every project with a free consultation and a free 3D design, so you can see your future landscape rendered in detail before committing to anything.
For families who are rebuilding, that 3D step has proven especially valuable. After losing so much, being able to walk through your new outdoor space visually (to adjust the terrace, move the fire feature, see the planting mature) restores a sense of control over the process.

Building Resiliently
The Long View
The Palisades will come back, street by street, the way strong communities do. The homes being built now are safer and smarter than what stood before, and the landscapes around them should be too.
Line of Art Construction would be honored to be part of that work, building outdoor spaces that celebrate this extraordinary stretch of coastline while respecting what it has taught everyone about resilience.
Conejo Valley Landscaping FAQ
Questions Conejo Homeowners Ask Us
Does fire-wise landscaping mean giving up the garden?
No. Defensible space governs material close to the structure and plant spacing further out, not whether you have a garden. Noncombustible surfacing in the band against the house, outdoor living and hardscape in the next zone where paving doubles as a fuel break, and thinned, well-spaced planting beyond. Designed properly it reads as a finished landscape and performs under ember attack.
Who permits my project out here?
It depends on the parcel, and sometimes two bodies apply at once. Calabasas, Hidden Hills, Agoura Hills and the City of Westlake Village each run their own departments; the Ventura County side falls under Thousand Oaks. Westlake Village straddles the county line, so the postal address does not reliably tell you. On top of that, many properties sit in HOAs whose architectural review runs in parallel with city permitting. We confirm all of it for the specific address before designing.
What is the highest-value thing to build here?
Shade, on most properties. Summer afternoons in the corridor run hot and dry with intense sun, and a west-facing yard without cover goes unused for a third of the year regardless of how well it is finished. A patio cover, pergola or well-placed tree changes usable hours more than any material upgrade — and it can be specified to satisfy fire-zone rules and HOA review at the same time.
Can you work alongside my architect and general contractor on a rebuild?
Yes. We coordinate with your architect and general contractor so outdoor construction sequences correctly with the house: driveway and flatwork after heavy equipment is done, planting and finish work last.
Do you build retaining walls on Conejo slopes?
Yes, and on most parcels here it is the first thing that has to happen. Reinforced masonry, segmental systems with geogrid, and poured concrete where loads demand it, with drainage designed before the wall. Permit height is measured from the bottom of the footing, so walls that look modest frequently need engineering. We confirm thresholds with the governing department for your parcel.
Is the consultation and 3D design free?
Yes. Every project begins with a free consultation and a free 3D design, so you can see your future landscape rendered in detail before committing to anything.
