Concrete work in San Marino
San Marino is small and almost entirely residential: incorporated in 1913, about 3.77 square miles, 12,513 residents at the 2020 census, and seven residential zones set by minimum lot size, from about 4,500 square feet to more than 30,000. Most of its homes were built between 1920 and 1950, and the city is home to The Huntington and the 30-acre Lacy Park. Bigger lots mean bigger concrete jobs: long driveways, motor courts, terraces, garden walls and pool decks.
San Marino's Design Review Committee and concrete
San Marino reviews the look of a property more closely than most cities. Its Planning and Building FAQ lists what the Design Review Committee typically reviews:
| Item | Reviewed? | Concrete angle |
|---|---|---|
| All new homes | Yes | Foundations, drives and hardscape come with the house |
| Certain one-story and all two-story additions | Yes | New foundations and patios around them |
| Front yard walls, gates and fences | Yes | Garden and retaining walls facing the street |
| Certain accessory structures visible from public view | Yes | Pool houses, garages and their slabs |
| Driveways and flatwork | Not addressed in the FAQ | Ask Planning and Building |

Concrete jobs on San Marino lots
Driveways and motor courts
Long drives, turnarounds and motor courts in front of the garage are common on San Marino's larger lots. They are built to the same spec as any concrete driveway, but at this size the joint layout, drainage and finish carry more weight; a large plain slab looks very different from one with a border or a pattern.
Stamped and decorative work
Spanish Colonial and other period houses here pair well with colored, patterned stamped concrete or exposed aggregate with a brick border.
Pool decks and terraces
A pool deck that is worn, hot underfoot or tipping toward the pool can be resurfaced or replaced; see the concrete pool deck page for cool, grippy finishes.
Concrete prices for San Marino
No source prices concrete for San Marino alone. Area figures from constructlytools' Los Angeles guide (updated May 19, 2026): reinforced driveways at $8 to $15 per square foot, stamped concrete and pool decks at $15 to $20, and decorative finishes such as exposed aggregate at $12 to $20. The patio cost page has sizes. The soil and geology guide covers the Raymond Fault, which runs through the city.
