Backyard Remodeling in San Dimas
Backyard remodeling in San Dimas typically begins with a single problem: a patio cover that has failed, an outdoor kitchen that never existed, or a lawn that finally stopped being worth the effort. The residential tracts here were laid out after the city incorporated in 1960, growing from an 1887 railroad townsite and decades of orange groves, and the age of those lots often shows up out back first, in mature tree roots, cracked old slabs, and drainage nobody ever properly planned. We work across Via Verde, West San Dimas, and neighborhoods near the Bonita Avenue downtown, handling everything from a complete design-build yard to a targeted tear-out and rebuild, drawn as one plan and built by one licensed general contracting team.

Our Backyard Remodeling Process in San Dimas
Backyard remodeling in San Dimas starts with a site visit, because what sits underground determines everything that gets built above it. We walk the lot to read the slope, check side-yard access, note where the gas meter and electrical panel land, and trace how water moves across the property now. On renovation work we also look closely at what is failing and why, and at any structure that may never have carried a permit through the City of San Dimas Building and Safety Division. From there we survey the full lot, setbacks and easements included, and draft a complete yard plan covering decking, shade structures, an outdoor kitchen, planting beds, grades and drains. You make your selections before demolition begins, and we handle engineering coordination, permit submittals and any design review filings required under the city’s architectural guidelines.
Once approvals are in place, demolition and excavation begin. Underground runs for gas, electrical, plumbing, drainage and irrigation go in next, each inspected before we cover them. Because many San Dimas residential tracts were built on foothill lots after the city incorporated in 1960, grading and drainage details often need more attention than a flat suburban yard would require. Structures and hard surfaces follow the underground phase, then planting, lighting, equipment start-up, final inspections and a walk-through with you.

Backyard remodeling in San Dimas moves through a clear permit and review process, and understanding it early saves time. Most scope items require a permit from the City of San Dimas Building and Safety Division: pools and spas always, patio covers and California rooms, any new gas line serving a grill, fire pit, or pool heater, new electrical circuits, retaining walls, and grading past the local limits. San Dimas also has specific plan areas that carry Early California and Western architectural guidelines, and exterior work in those zones goes through the design review process set out in Chapter 18.12 of the zoning code. The city’s residential tracts grew mostly after incorporation in 1960, and a good share of those suburban foothill lots fall inside or near those plan areas, so we check the zoning map at the start of every project rather than discovering it at plan check. Where a homeowners association exists, its architectural committee typically reviews pools, covers, walls, and visible landscape changes before the city does, and we build that review window into the schedule.
Setbacks for pools, equipment pads, covers, and fire features vary by city, so we confirm the exact numbers during layout. Drainage gets the same early attention. Every new patio, pool deck, or solid cover roof adds hard surface, and water that once soaked into lawn now runs off instead. 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 where hardscape meets the structure. Permeable pavers, gravel, or planting fill spots where they fit. Water routes to an outlet the city allows, usually the street, never over a fence onto a neighbor’s lot.
Retaining walls bring their own requirements. Many building departments require a permit for any wall over four feet measured from the bottom of the footing, or for a wall holding back a slope, driveway, or structure. A wall also needs drainage behind it to stay standing long term. On the landscape side, California’s Model Water Efficient Landscape Ordinance applies to new and rehabilitated landscapes, adopted by every city and county at the state standard or stricter. Smaller backyard rehabs often fall under the thresholds, but larger permitted landscapes can require a water budget and an irrigation plan with the submittal. If your water agency offers a turf replacement rebate, the approval has to come before any grass is removed, the replacement area has to stay permeable, and synthetic turf does not qualify.
If your address sits in a CAL FIRE mapped Fire Hazard Severity Zone, the planting and material choices near the house change. The first five feet around the structure, Zone 0, are the most critical, so we use hardscape or gravel there rather than bark mulch, keep fire features clear of structures, overhangs, and trees, and specify ignition-resistant materials for attached covers. Pool and spa projects carry one more requirement regardless of location: 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 the final inspection. We review which features fit your layout during the design phase so there are no surprises at the end of the project.

Why Choose Horizon Remodeling For Backyard Remodeling in San Dimas
Horizon Construction and Remodeling has been a licensed and bonded Class B general building contractor since 2009, serving homeowners across Southern California. A Class B license is the right fit for backyard work because these projects routinely pull together framing, drainage, electrical, plumbing and gas under one scope rather than one trade at a time.
We handle the work design-build, meaning design, engineering coordination, permits and construction all run under a single contract with one project manager guiding the job. That matters in San Dimas, where exterior work in parts of the city falls under Early California and Western architectural guidelines and goes through a design review process before permits are issued through the City of San Dimas Building and Safety Division. Having one team manage those steps keeps the project moving without gaps between whoever drew the plans and whoever builds them.
Most homes in San Dimas sit on suburban footprint tract lots developed after 1960, and our project manager understands how to work within those lot configurations from the first site visit through the final inspection. Call (714) 449-9035 to schedule that visit.

Backyard Remodeling FAQ
Do I need a permit for a backyard remodel in San Dimas?
Most backyard remodeling work in San Dimas does require a permit, though minor jobs like replacing plants or resurfacing a small patio typically do not. Patio covers, California rooms, pool and spa construction, taller retaining walls, significant grading, new gas lines, and new electrical circuits all go through the City of San Dimas Building and Safety Division. Because parts of the city carry Early California and Western architectural guidelines, exterior work may also run through the local design review process before permits are issued. Gas, electrical, and plumbing runs are inspected before they are buried, and pool projects must include state-required drowning-prevention features to reach final. We review the applicable rules during the layout phase, prepare the drawings, pull every permit the project requires, and work through plan-check comments until everything is approved.
How long does a backyard remodel take?
How long a backyard remodeling project takes in San Dimas depends on its scope, permit timing, any HOA review, and how quickly material selections get finalized. A hardscape-and-planting job can wrap up in a few weeks of construction once permits are cleared through the City of San Dimas Building and Safety Division, though design review under the city’s zoning guidelines can add time for exterior work in certain areas. A yard combining a patio cover, outdoor kitchen, and new pool commonly runs a few months, with design and permitting sometimes matching the build phase in length. Drainage work or engineered retaining walls adds additional time up front. We provide a project-specific schedule with your proposal.
What drives the cost of a backyard remodel?
Backyard remodeling costs in San Dimas vary based on a range of site-specific factors, and no two projects land at the same number. Access matters first: a yard reachable only through a narrow side gate limits equipment size and increases hand labor. Slope and soil conditions shape excavation scope and determine whether retaining walls are needed. On the foothill tract lots common across subdivisions like Via Verde, grade changes are frequent enough that this step alone can shift a budget considerably. A new pool carries different costs than a remodel, and reopening an older pool often reveals plumbing that needs replacement. 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 all affect the final figure. Permits route through the City of San Dimas Building and Safety Division, and exterior work in certain plan areas goes through a design review process as well.
What's the difference between a backyard remodel and a backyard renovation?
Backyard remodeling in San Dimas typically falls into one of two categories, and many projects are both at once. Sometimes you are starting fresh, adding hardscape, a covered patio, an outdoor kitchen, or landscaping as a coordinated plan. Other times the work begins with what has already failed: cracked or heaved concrete, a rotting deck, poor drainage, dead lawn, or unpermitted structures that have to be removed before anything new can go in. On the foothill tract lots that make up most of San Dimas, grading and underground drainage have to be figured out before any surface work is laid down, and exterior improvements that affect the appearance of the property may move through the City of San Dimas Building and Safety Division along with the design review process outlined in the local zoning code. We approach both types of project the same way, working through drainage and underground conditions first so the finished surfaces hold up.
Can we build the backyard in phases?
Yes, phasing a backyard remodel is both possible and common, especially on the suburban tract lots throughout San Dimas where homeowners often tackle outdoor projects in stages. The approach works best when we map the entire yard before any ground is broken, then complete all underground runs for gas, electrical, plumbing, drainage, and irrigation during the first phase so later work never requires cutting through finished concrete or pavers. If an outdoor kitchen, fire pit, or covered structure might come later, we place the gas line or conduit under the new slab now. The trade-off is paying for mobilization and some inspections more than once.
Can you keep my pool and replace everything around it?
In many cases, yes, you can keep the pool and still fix the surrounding area. Older pools common to San Dimas tract homes often have a structurally sound shell paired with a failed surround, meaning a cracked or lifted deck, loose coping, and an expansion joint allowing water beneath the slab. We replace the deck and correct the drainage that caused the damage while the pool remains in place. When the pool itself also needs resurfacing, new tile, or equipment work, we coordinate both scopes together so the concrete is not poured twice.
