Backyard Remodeling in Agoura Hills
Backyard remodeling in Agoura Hills typically starts with a single problem: a patio cover that has deteriorated, an outdoor kitchen that never got built, or a yard that stopped working years ago. The homes across Old Agoura, Morrison Ranch, Lake Lindero, and Liberty Canyon were largely built in the 1970s and 1980s, and the age of a lot tends to show up out back first, in mature tree roots, old slabs, and drainage that was never properly designed. We handle both complete design-build yards and targeted tear-out-and-rebuild projects, drawn as one plan and built by one licensed team coordinating every trade involved.

Our Backyard Remodeling Process in Agoura Hills
Backyard remodeling in Agoura Hills starts with a site visit, because the sloped hillside and canyon lots that define so much of the city’s 1970s and 1980s tract housing demand a close look before any design decisions are made. We assess the grade, side-yard access, existing structures, and where drainage currently goes. We also check for work that may never have been permitted through the City of Agoura Hills Building and Safety Division, since unpermitted conditions have to be resolved before new construction can move forward. From there we survey setbacks and easements, draw the full yard plan, and take you through selections before a single shovel hits the ground.
Because the entire city sits within a CAL FIRE designated Very High Fire Hazard Severity Zone, exterior material choices are shaped by wildland-urban interface standards from the beginning, not added as an afterthought. We coordinate any required engineering, prepare permit submittals, and handle HOA documentation where applicable. Underground work for drainage, gas, and irrigation is inspected and approved before it is covered. Structures and surfaces follow in sequence, finishing with equipment start-up, final inspections, and a walk-through with you.

Backyard remodeling in Agoura Hills moves through the City of Agoura Hills Building and Safety Division, and the permit list is longer than most homeowners expect. Pools and spas always require permits, and so do patio covers, California rooms, new gas lines serving grills, fire pits or pool heaters, new electrical circuits, and retaining walls or grading that exceeds local thresholds. Many building departments treat a retaining wall as a permitted structure once it reaches four feet measured from the bottom of the footing, or whenever it holds back a slope, a driveway, or another structure. A wall also needs drainage behind it to stay standing over time. Because setbacks for pools, equipment pads, covers, and fire features vary from one city to the next, we confirm them during the layout phase rather than waiting until plan check to discover a conflict. Where an HOA is in place, its architectural committee typically reviews pools, covers, walls, and visible landscape changes before the city does, and we build that review into the schedule from the start.
Agoura Hills was built out largely in the 1970s and 1980s, after the Ventura Freeway opened the area and before the city incorporated in 1982. The result is a stock of detached tract homes, many of them sited on sloped hillside and canyon lots rather than flat pads. That topography matters for drainage, because every new patio, pool deck, and solid patio cover roof adds hard surface, and water that once soaked into the lawn has nowhere to go. We set grades in the drawings so the ground falls away from the house on every side, tie downspouts into drain lines, and add area or channel drains wherever hardscape meets the foundation. Permeable pavers, gravel, or planting fill the spots where hard surface is not required. Water is directed to an outlet the city allows, typically the street, and never onto a neighboring lot.
The sloped lots common in areas like Old Agoura, Morrison Ranch, and Lake Lindero also affect how landscape work is permitted. California’s Model Water Efficient Landscape Ordinance applies to new and rehabilitated landscapes, with every city and county adopting it or a stricter local version. Smaller backyard projects often fall under the thresholds, while larger permitted landscapes can require a water budget and an irrigation plan as part of the submittal. If a homeowner is replacing a lawn and the water agency offers a turf replacement rebate, approval must come before any grass is removed, the replacement area must remain permeable, and synthetic turf does not qualify under those programs.
Every property in Agoura Hills sits within a CAL FIRE designated Very High Fire Hazard Severity Zone, which means wildland-urban interface construction standards apply to all exterior work here. Near the house, CAL FIRE treats the first five feet as the highest-priority zone, so we use hardscape or gravel in that area rather than bark mulch, keep fire pits set well clear of structures, overhangs, and trees, and design attached covers with ignition resistance in mind from the beginning. Pool projects carry an additional requirement: when a permit is issued for a new or remodeled pool or spa at a single-family home, state law requires at least two of seven drowning-prevention features to be in place before final inspection passes.

Why Choose Horizon Remodeling For Backyard Remodeling in Agoura Hills
Backyard remodeling in Agoura Hills calls for a contractor whose license actually covers the full scope of the work. A Class B General Building license is built for jobs where framing, drainage, electrical, plumbing and structural elements all land on the same project, which is exactly what a serious backyard renovation involves. Horizon Construction and Remodeling Inc. has held that license since 2009 and is licensed and bonded.
Most homes in Agoura Hills were built in the 1970s and 1980s on sloped hillside and canyon lots, and that terrain shapes how a backyard project gets planned and permitted. Grading, retaining walls and drainage details matter more on a hillside pad than on flat ground, and because the entire city sits in a CAL FIRE designated Very High Fire Hazard Severity Zone, exterior materials and construction methods must meet wildland-urban interface standards. Permits for this work go through the City of Agoura Hills Building and Safety Division, and we handle that coordination as part of the project.
Design, engineering coordination, permitting and construction all sit under one contract with one project manager on our end. Specialty trade portions are performed by appropriately licensed subcontractors we coordinate, so you are not managing separate companies who each see only their piece of the job. Call (714) 449-9035 to request a free estimate and set up a site visit.

Backyard Remodeling FAQ
Do I need a permit for a backyard remodel in Agoura Hills?
Most backyard remodeling work in Agoura Hills does require permits, though smaller jobs like replacing plants or resurfacing a compact patio typically do not. Projects such as patio covers, California rooms, pools and spas, taller retaining walls, significant grading, and new gas or electrical circuits all go through the City of Agoura Hills Building and Safety Division. Gas, electrical, and plumbing runs are inspected before burial, and pool construction must include state-required drowning-prevention features to pass final inspection. Because the entire city falls within a CAL FIRE designated Very High Fire Hazard Severity Zone, wildland-urban interface standards also apply to exterior work on these hillside and canyon properties. We review local requirements during layout, prepare the drawings, pull every permit the project needs, and respond to plan-check comments until approvals are issued.
How long does a backyard remodel take?
Timeline depends on scope, permit timing, HOA review, and how quickly selections are made. A hardscape-and-planting job can run a few weeks of construction once permits are in hand. A yard with a new pool, patio cover, and outdoor kitchen commonly takes a few months, and design and permitting can take as long as the build itself. On the sloped canyon lots found throughout Agoura Hills, tear-out with drainage work or engineered walls adds time up front. You get a project-specific schedule with the proposal.
What drives the cost of a backyard remodel?
Backyard remodeling costs in Agoura Hills vary widely based on site conditions and project scope. Because so many homes here sit on sloped hillside and canyon lots, slope and soil conditions directly shape excavation needs and whether retaining walls are required. Access matters too: a yard reachable only through a narrow side gate limits equipment size and increases hand labor. For pool work, a new build is priced differently than a remodel, and an older pool may need plumbing replacement once it is opened. Distance from the gas meter and electrical panel, panel capacity, the type of patio cover selected, material choices, demolition and haul-off volume, and any HOA, fire-zone, or landscape submittals required by the City of Agoura Hills Building and Safety Division all affect the final number.
What's the difference between a backyard remodel and a backyard renovation?
Backyard remodeling in Agoura Hills can mean building something new, fixing what has failed, or both at once. A project might center on new hardscape, a covered patio, an outdoor kitchen, and landscaping planned together as a single scope. It can equally mean tearing out cracked or heaved concrete, replacing a rotting deck, correcting poor drainage, or removing unpermitted structures before anything is rebuilt. On the sloped hillside and canyon lots common across neighborhoods like Old Agoura and Lake Lindero, drainage and underground work get designed before any surface goes in.
Can we build the backyard in phases?
Yes, phasing a backyard remodeling project in Agoura Hills is common and very workable. The right approach is to map the entire yard before breaking ground, then run all underground work for gas, electrical, plumbing, drainage, and irrigation in the first phase so later additions never require cutting through finished concrete or pavers. On the hillside and canyon lots typical of neighborhoods like Lake Lindero or Morrison Ranch, getting that rough-in right the first time matters even more. If an outdoor kitchen, fire pit, or covered structure might come later, we run the gas line or conduit now. The trade-off is that phasing adds mobilization costs and may require separate inspections for each phase.
Can you keep my pool and replace everything around it?
In many cases, yes, you can keep the pool while we rebuild the surround. A sound shell with a failing deck is a common situation in Agoura Hills, where tract homes from the 1970s and 1980s sit on sloped lots that put extra stress on concrete over time. Cracked or lifted decking, loose coping, and a compromised expansion joint letting water beneath the slab are all fixable without touching the pool itself. We address the drainage issues driving the damage at the same time, and if the pool also needs resurfacing, tile, or equipment work, we schedule everything together so the deck is poured once.
