Hardscape & Outdoor Living in San Marino
Hardscape problems almost always start below grade, in a base that was laid too thin or a drainage path that was never planned at all. Horizon Construction and Remodeling handles patios, driveways, entries, retaining walls, steps and fire pits in San Marino, with drainage designed in from the beginning rather than added as an afterthought. Because the city’s housing stock is overwhelmingly prewar, most of it built between 1920 and 1950 on lots carved from the old Shorb ranch after the city incorporated in 1913, a great many yards in the Lacy Park area, along Huntington Drive, in the Mission Street district and on the Oak Knoll and Monterey Road blocks still carry original slabs, walks and walls that have settled, cracked or begun to lean. We manage design, permit coordination through the City of San Marino Building and Safety Division and construction under a single contract.

Our Hardscape & Outdoor Living Process in San Marino
Planning hardscape and outdoor living in San Marino begins with a thorough site visit, because the generous lots common here, many exceeding 30,000 square feet, present real grading and drainage complexity that has to be understood before a line gets drawn. We assess existing slabs and walls, soil conditions, utility locations, how water moves across the yard, and how equipment will access the space. That information drives an in-house layout covering finished grades, drain placement, wall details and materials, so revisions happen on paper rather than after concrete is poured. Where a retaining wall or subsurface condition calls for it, a structural or geotechnical engineer joins the process.
Because exterior changes in San Marino receive closer design review than in most neighboring cities, we account for that scrutiny early. Permits go through the City of San Marino Building and Safety Division, and we handle all required building, plumbing or encroachment filings before work begins. Utilities are located prior to any digging, then drain lines, sub-drains, gas lines and conduit are set while the ground is open. The base goes in with compacted lifts and built-in slope, followed by walls, steps and the finished surface. A final inspection and walk-through with you close out the project.

Exterior work in San Marino moves through the City of San Marino Building and Safety Division, and the process here is more involved than in most surrounding cities. The city’s design review and zoning rules are written to preserve the residential character that has defined these blocks since homes were first laid out on the old Shorb ranch land in the years following the 1913 incorporation. That means a patio, a pergola, a low garden wall, or a new driveway approach is likely to receive closer scrutiny from the city than a comparable project in a neighboring community. We map out what approvals your specific lot requires before any design goes final, because finding out late costs time and money.
The permit question people ask most often is about retaining walls. A wall that reads as three feet above grade can cross the common four-foot exemption once the footing depth is added in, and that exemption only holds when the wall is not supporting a surcharge above it, such as a slope, a driveway, or a structure. Every wall we build, permitted or not, gets a perforated drain line bedded in gravel behind the face, with outlets to carry water away from the wall, because saturated soil is the force that pushes walls over. That drainage detail is not optional on the large, generously graded lots that are typical throughout the Oak Knoll and Monterey Road blocks and the Huntington Drive corridor.
Drainage thinking extends well beyond retaining walls. Parts of Southern California sit on expansive clay that swells when wet and contracts as it dries, so we grade surfaces away from the house, route downspouts into the system, and add area or channel drains wherever paving cannot shed water on its own. Los Angeles County’s Low Impact Development requirements apply when a project alters half or more of a lot’s impervious surface, which is a real consideration on the oversized lots common here. Permeable pavers are one tool, though on heavy clay soils they typically need an underdrain to function properly.
Gas lines serving fire features, lighting circuits, and attached patio covers each trigger their own permit requirements, separate from any structural review. Driveway approaches and curb cuts sit in the public right-of-way and need their own approval as well. Some cities also limit how much of a front yard can be paved or how tall a wall may be within the front setback, and San Marino’s design review standards make front-yard changes particularly worth discussing early. On lots within a mapped fire hazard zone, CAL FIRE guidance identifies the first five feet around the house as the highest priority area, where pavers, concrete, or gravel belong in place of bark or mulch.

Why Choose Horizon Remodeling For Hardscape & Outdoor Living in San Marino
Horizon Construction & Remodeling Inc. is a licensed and bonded Class B general building contractor, in business since 2009 and serving the San Marino area. Because so many homes here were built between 1920 and 1950 on large, formal lots, outdoor living projects often involve more groundwork than they appear to at first glance. Grading, drainage, and any structural retaining elements have to be thought through together from the start, not sorted out after a concrete crew has already finished its portion of the job.
San Marino applies strict design review alongside its standard building permit process through the City of San Marino Building and Safety Division, which means exterior work on these older properties receives a closer look than it would in most neighboring cities. We coordinate the permit drawings and inspection scheduling so that burden does not fall on you. One project manager stays with the job from the initial site visit through final sign-off.
Our proposals separate demolition, base preparation, drainage, walls, and surface materials into individual line items. That structure lets you compare what different bids are actually pricing, including the work that disappears beneath the finished surface. Call (714) 449-9035 to request a free estimate for your outdoor project.

Hardscape & Outdoor Living FAQ
Do I need a permit for hardscape in San Marino?
A paver or concrete patio at grade generally needs no permit on its own, but retaining walls above the exemption or carrying a surcharge, gas lines to fire pits, lighting circuits, attached patio covers, and driveway work in the public right-of-way do. Those go through the City of San Marino Building and Safety Division. San Marino’s strict design review adds scrutiny to any exterior change, so we verify current requirements and handle the applications during design.
Pavers or concrete for a driveway?
Pavers and poured concrete both perform well when the base is properly prepared. Because pavers are individual units, they flex with minor ground movement rather than cracking, and any section can be lifted and reset if a utility line needs access below. A concrete slab is simpler to clean, though control joints are needed to keep inevitable cracks from running randomly across the surface. San Marino’s generous lots often sit on clay-heavy soil, which is one reason we frequently favor pavers on projects here.
How tall can a retaining wall be without a permit?
Most jurisdictions exempt retaining walls up to 4 feet tall, measured from the bottom of the footing to the top of the wall, provided no surcharge from a slope, driveway, pool, or structure loads the wall. Some cities set a lower limit near slopes. Because San Marino’s Building and Safety Division scrutinizes exterior changes closely, we confirm the local rule with the building department before a wall is designed.
How long does a hardscape project take?
Hardscape timelines in San Marino vary by scope, and we give you a schedule with the proposal along with updates if inspections or weather shift it. A patio or driveway replacement typically takes a few weeks on site once materials and permits are in hand, though San Marino’s design review process means exterior work often requires closer scrutiny before construction can begin. Engineered retaining walls, gas lines, or encroachment permits add time before and during the build. A full yard with walls, drainage, and a fire feature can run a couple of months.
What drives the cost of hardscape?
Most of what drives the budget is underground and out of sight. Removing old concrete, equipment access, soil conditions, base depth, drainage pipe and drains, and engineered walls with footings, steel, and sub-drains carry a large share. Surface materials, pattern cuts, gas and electrical work, and permits add to that. On San Marino’s large lots, site conditions vary, and your written proposal breaks each item out.
Can you work with my HOA and plan for later phases?
Yes, we handle the drawings and material samples required for design review and fold that approval process directly into the project schedule. San Marino’s strict oversight of exterior changes means this step matters more here than in most nearby cities, particularly for properties along corridors like Huntington Drive or blocks near Oak Knoll. When future additions such as a patio cover or outdoor kitchen are part of the plan, we rough in drains, gas stubs, and conduit beneath the new paving now, so the next phase doesn’t require breaking up finished work.
