Serving San Marcos, CA — 92069 & 92078
Landscape Construction in San Marcos, CA
Terraced walls, pavers, outdoor kitchens, and full backyard builds — designed for San Marcos's rolling hills, Twin Oaks Valley views, and the master-planned communities around Lake San Marcos and Cal State San Marcos.
San Marcos is a city of hillside lots and master-planned neighborhoods. From the ridgeline view properties in San Elijo Hills to the newer-build pads in Discovery and Old Creek Ranch, the yards here ask for two things at once: real engineering for the slope, and design that fits inside an HOA's approved palette. It is a different kind of build than coastal Carlsbad and a different climate than inland Escondido — warmer than the coast, cooler than the valley, with the marine layer thinning out as you head east toward Twin Oaks.
SANZ Landscape Construction has been building outdoor spaces across North County for years, and a steady share of that work is in San Marcos — both the brand-new pads that need a first landscape from scratch and the older yards in Richland, Coronado Hills, and around Lake San Marcos that are getting refreshed after twenty or thirty years. Terraced retaining walls, paver driveways tied to HOA-approved palettes, patio covers and outdoor kitchens sized for the bigger newer lots, and full backyard transformations — built to last, run cleanly, and approved through whatever review committee your community runs.
Services for San Marcos Homeowners
What We Build for San Marcos Homes
Hillside & View-Lot Specialty
Terraced Retaining Walls for San Marcos View Lots
San Elijo Hills, the upper streets of Old Creek Ranch, and the Twin Oaks Valley hillsides are full of homes where the buildable pad ends and the slope falls away into a view. Without a wall, that drop is dead space; with the right wall, it becomes a flat, usable terrace for a patio, a lawn, a pool, or a planted garden.
We build multi-tier walls — stacked block, stone-veneered, and poured concrete — with full footings, sub-drains, and reinforcement engineered for the slope. For HOA-driven communities like San Elijo Hills we match the approved wall caps and veneer palette from day one, and for walls over 3 feet or any wall holding a driveway we pull the City of San Marcos permit and engineering as part of the proposal.
Pavers, Concrete & Driveways
Pavers and Concrete for Master-Planned Neighborhoods
In Discovery, Rancho Tesoro, and the newer streets of Old Creek Ranch, most driveways and side yards are still original builder concrete. We install Belgard, Angelus, and Calstone paver driveways, walkways, and side-yard runs that tie into the HOA's approved color and pattern palettes — so the upgrade reads as designed, not bolted on.
Every install gets the right base prep: deep aggregate, plate compaction in lifts, edge restraint, and polymeric joints. That is what keeps a San Marcos driveway flat after the wet seasons instead of dipping at the apron or rocking under the tires.
Outdoor Living
Outdoor Kitchens, Fire Features & Patio Covers
The newer-construction lots in San Elijo Hills and Discovery are bigger than what you find closer to the coast, and the climate near Twin Oaks Valley runs cooler in the evenings than coastal Carlsbad — which makes San Marcos one of the better spots in North County to actually use an outdoor kitchen and a fire feature year-round. We build full kitchens with built-in grills, side burners, refrigeration, and counter seating; linear gas fireplaces and wood-burning fire pits; and structural patio covers in wood, aluminum, and louvered designs that meet HOA roofline and finish standards.
It all gets designed as one finished space — kitchen, cover, seating, fire, and lighting tied together — instead of arriving as separate add-ons.
Builder-Grade to Custom
Full Backyard Builds in San Marcos
A lot of San Marcos homes are sold with a graded pad and a square of sod — and that is it. Discovery, San Elijo Hills, Foxhall, and Rancho Tesoro all close out with backyards that are basically a blank canvas, and we handle the full build from there: grading, drainage, terraced walls, hardscape, patio cover and structural work, outdoor kitchen, plantings, irrigation, and lighting under one contract and one crew.
For older yards in Richland, Coronado Hills, or the Lake San Marcos area, the work usually starts with a full demo of the original 1990s hardscape and tired turf and lands as a fully refreshed, builder-grade-to-custom remodel.

On-Site Walk

Design & HOA Prep
For HOA neighborhoods like San Elijo Hills, we prepare 3D renderings and the material samples your ARC submittal needs before construction starts.

Our own crews stay on the job site consistently so San Marcos projects move from grading to plantings without long quiet stretches.

Why Homeowners Choose Us
What San Marcos Homeowners Say After the Job
Straight Answers, Not Sales Pitches
We tell you what is realistic for your lot, your HOA, and your budget — even when the answer is "scale this back."
Built for HOA Approval
San Elijo Hills, Rancho Tesoro, and Discovery all have design committees. We design for that first, so submittals do not bounce.
In-House Crews
Our wall, hardscape, and structural crews are our own people — not a rotating set of subs — so the quality and the schedule actually hold.
No Mystery Pricing
Every San Marcos proposal is itemized. You see what each wall, each paver square, and each fixture costs before signing.
Local Builders Who Know San Marcos Lots
We are not a national franchise stamping out the same yard in every city. We are a North County crew that builds in San Elijo Hills slope, Discovery clay, Old Creek Ranch decomposed granite, and the older Richland and Coronado Hills lots every single week — and that day-to-day experience is what keeps walls from cracking, drainage from failing, and HOAs from sending things back.
If you are planning a backyard project in San Marcos, we would be glad to walk your property, talk through the slope and the HOA constraints, and put together a clear, itemized proposal.
San Marcos Project FAQ
Common Questions From San Marcos Homeowners
Yes. A lot of our San Marcos work happens on terraced view lots in San Elijo Hills, Old Creek Ranch, and the hillsides above Twin Oaks Valley. We engineer multi-tier retaining walls, terraced patios, and stairway transitions so a sloped backyard becomes flat, usable space — and we handle the City of San Marcos permits and engineering when wall heights require it.
A targeted project — patio, side yards, and a single wall run — typically takes 4 to 8 weeks once we break ground. A full San Marcos backyard build with terraced walls, an outdoor kitchen, fire feature, patio cover, and full plantings usually runs 8 to 16 weeks. HOA-heavy neighborhoods like San Elijo Hills can add 2 to 4 weeks on the front end for design review and submittals, and we build that into the schedule up front.
Yes — and a large share of San Marcos work runs through an HOA. San Elijo Hills, Old Creek Ranch, Rancho Tesoro, and Discovery all have architectural design committees with their own approved material palettes, wall finishes, and roof or pergola standards. We design to those palettes from day one, prepare the renderings and material samples the ARC needs, and stay involved through approval so there are no surprises during construction.
The City of San Marcos generally requires a building permit for any retaining wall over 3 feet (measured from the bottom of the footing) and for any wall holding back a surcharge — like a driveway, pool deck, or upslope structure. On terraced view lots we often stack multiple walls under 3 feet, which can simplify permitting, but the engineering still matters. We pull every required permit and get a structural engineer involved when wall design calls for it.
Most San Marcos projects land between $45,000 for a focused hardscape and planting refresh and $225,000+ for full builder-grade-to-custom backyard transformations with terraced walls, outdoor kitchens, patio covers, and fire features. Newer San Elijo Hills and Discovery homes often start from a blank pad, which can run efficiently; tighter older lots in Richland or Coronado Hills may need more import and access planning. We walk the property and price every line item before you commit.
We cover both 92069 and 92078 — including San Elijo Hills, Discovery, Old Creek Ranch, Foxhall, Lake San Marcos, Twin Oaks Valley, Coronado Hills, Richland, Rancho Tesoro, and the University District around Cal State San Marcos. We also serve neighboring cities including Escondido, Vista, Carlsbad, and Encinitas.
