Hardscape & Outdoor Living in Calabasas
Hardscape failures almost always start below the surface, in bases laid too thin or drainage that was never planned at all. Horizon Construction and Remodeling handles patios, driveways, entries, retaining walls, steps and fire pits in Calabasas, with drainage worked into the design from the beginning rather than added as an afterthought. The city incorporated on April 5, 1991 as the newest city in Los Angeles County, but most of its hillside tract homes were built well before that, and plenty of yards still have original slabs, walks and walls that have since settled, cracked or started to lean. We work in Old Town Calabasas, Calabasas Hills, Park Moderne and The Colony, managing design, permits and construction under a single contract.

Our Hardscape & Outdoor Living Process in Calabasas
Hardscape and outdoor living in Calabasas begins with a careful site visit, because the hillside lots that define most of the city’s planned subdivisions rarely drain or grade the way a flat yard would. We read the existing slope, trace where water moves, assess the soil, and note every utility and access point before a line gets drawn. Many of these homes were built between the 1970s and 1990s, and their original slabs and retaining walls often need evaluation before new work goes on top of them. If a wall or the soil condition calls for a structural or geotechnical engineer, we bring one in. We also check whether any protected oaks are near the work area, since the city’s Oak Tree Ordinance can require a separate oak tree permit before construction begins.
Once the design is set on paper, we pull the required permits through the City of Calabasas Building and Safety Division before breaking ground. Utilities get located, then excavation opens the ground for drain lines, sub-drains, conduit and any gas runs. The base goes in with compacted lifts and built-in slope, followed by walls, steps and the finished surface. A final inspection and a walk-through with you close out the project.

Permits for hardscape and outdoor living work in Calabasas go through the City of Calabasas Building and Safety Division. Before any design is final, we confirm exactly what applies to your lot, because the requirements vary more than most homeowners expect. A patio laid at grade typically does not need a building permit on its own, but retaining walls over the standard exemption, gas lines serving fire features, lighting circuits, and attached patio covers all generally do. Getting that sorted early keeps the project moving.
The Oak Tree Ordinance is a local factor that comes up often on the hillside and gated tract properties that make up most of the housing stock here. Many of those homes, built across the decades before the city incorporated in 1991, were graded into sloped lots where mature oaks were left standing. Under Section 17.32 of the municipal code, work near a protected oak can require an oak tree permit before construction begins, so we identify any protected trees on your property at the start of planning rather than mid-project. Retaining walls are where most code questions land. The common exemption covers walls no taller than four feet measured from the bottom of the footing to the top of the wall, and only when the wall is not supporting a surcharge such as a slope, driveway, pool, or structure above it. A wall showing three feet above grade can exceed four feet once the footing depth is counted, and some jurisdictions apply stricter standards near slopes.
Drainage matters as much as any surface material. Parts of Southern California sit on expansive clay soil that swells when wet and shrinks as it dries. Every retaining wall we build, permitted or not, gets a perforated drain line and gravel backfill with proper outlets, because saturated soil is the main reason walls fail. We grade away from the house, add area or channel drains where paving cannot shed water naturally, and tie downspouts into the overall system.
Stormwater rules increasingly favor keeping rain on the lot. Los Angeles County Low Impact Development requirements can apply when a project alters half or more of a lot’s impervious surface, and permeable pavers can help meet that threshold, though on heavy clay they typically need an underdrain. Driveway approaches and curb cuts in the public right-of-way require their own permits, and many HOAs common in communities like Calabasas Hills or The Colony review front-yard hardscape plans, so we prepare the drawings and material samples their committees request. On lots within a mapped fire hazard zone, CAL FIRE guidance places the highest priority on the first five feet around the structure, where pavers, concrete, or gravel are appropriate in place of bark or mulch.

Why Choose Horizon Remodeling For Hardscape & Outdoor Living in Calabasas
Horizon Construction and Remodeling is a licensed and bonded Class B general building contractor, active since 2009 and based in Fullerton. For hardscape and outdoor living projects in Calabasas, that general contracting structure matters more than it might seem. Many of the hillside and gated tract homes built here before the city incorporated in 1991 sit on sloped lots where grading, drainage, and structural retaining walls all interact, and handling those elements under one plan from the start produces a more durable result than coordinating separate trades after the fact.
Permitting runs through the City of Calabasas Building and Safety Division, and any work near a protected oak tree may also require an oak tree permit under the city’s ordinance before construction begins. We account for those requirements during the planning phase rather than discovering them mid-project.
Our proposals break out demolition, base preparation, drainage, walls, and surface materials individually, so you can review each component and compare bids on the work that disappears once the pavers are set. One project manager runs the job from the first site visit through final inspection. Call (714) 449-9035 to request a free estimate.

Hardscape & Outdoor Living FAQ
Do I need a permit for hardscape in Calabasas?
A paver or concrete patio laid at grade typically does not require a building permit on its own, but retaining walls above the exemption height or carrying a surcharge, gas lines serving fire pits, lighting circuits, attached patio covers, and driveway work within the public right-of-way generally do. In Calabasas, those permits run through the City of Calabasas Building and Safety Division, and because many hillside lots here also fall under the city’s Oak Tree Ordinance, work near a protected oak may require a separate oak tree permit before construction can begin. We check the current requirements and manage the applications as part of our design process.
Pavers or concrete for a driveway?
Both paver and poured-concrete surfaces can work well for a Calabasas hardscape project, as long as the base preparation is done correctly. Pavers are individual units that flex with minor ground movement rather than cracking, and any section can be lifted and relaid if a utility line needs access later. Poured concrete is a single continuous slab that is straightforward to clean, though control joints are cut into it to keep inevitable cracks running in straight lines. On the clay soils common beneath the hillside tract homes that define most of Calabasas, we often lean toward pavers.
How tall can a retaining wall be without a permit?
Retaining wall permit thresholds vary by jurisdiction, but the exemption typically covers walls up to four feet measured from the bottom of the footing to the top of the wall, provided the wall is not supporting a surcharge such as a slope, driveway, pool, or structure above it. In hillside communities like Calabasas, some cities set lower limits for walls on or near slopes, so we confirm the applicable rule with the building department before the wall is designed.
How long does a hardscape project take?
Project timelines for hardscape and outdoor living in Calabasas vary by scope. A straightforward patio or driveway replacement typically runs a few weeks on site once materials and permits are secured, while a full yard buildout with retaining walls, drainage, and a fire feature can take a couple of months. Because many Calabasas properties sit on graded hillside lots developed before the city incorporated in 1991, engineered walls and drainage are common additions that extend the schedule. Gas line work, HOA review, encroachment permits for driveway approaches, or an oak tree permit required under the city’s Oak Tree Ordinance can also add time before or during construction. We include a project schedule with every proposal and keep you updated if inspections or weather cause shifts.
What drives the cost of hardscape?
Budget on a hardscape and outdoor living project in Calabasas goes largely toward work that stays hidden once the job is finished. Demolishing and removing old concrete, getting equipment onto hillside lots, reading soil conditions, setting proper base depth, running drainage pipe, and building engineered retaining walls with footings, steel, and sub-drains all claim a significant share of the cost. Surface materials, pattern cuts, gas and electrical portions handled by licensed subcontractors, and permits through the City of Calabasas Building and Safety Division add to that figure, and if the work falls near a protected oak, an oak tree permit may be required before construction can start. A written proposal itemizes each of those pieces separately.
Can you work with my HOA and plan for later phases?
Yes, we prepare the drawings and material samples an architectural committee requires and work their review into the project schedule from the start. For homes in gated Calabasas communities where HOA approval is common, that step is planned in advance, not added later. If a kitchen, patio cover, or future phase is on the horizon, we rough in drains, gas stubs, and conduit now so new paving never has to be broken up again.
