Large Lots, Long Ownership, Careful Work
San Marino is 82.8 percent owner occupied across roughly 4,500 housing units, which is about as high as it gets anywhere we work. The city sits in the San Gabriel Valley, and its R-1 land is divided into eight area districts by minimum lot size, from 9,000 square feet at the low end up to 60,000 in the estate district, with the average residential lot right around 15,000 square feet.
That ownership profile changes the job. These are people who have lived with a deck for years and intend to live with the repair for many more, so the questions are about durability and how the finished work looks. Larger lots also mean larger structures: terraces, long stair runs and elevated decks that are part of the architecture.
Sloping ground in the San Rafael Hills puts drainage ahead of coating in the sequence. Water leaving a terrace over its edge onto a grade is not being managed, it is being relocated. We settle the collection and discharge path first and then specify a system that serves it.
Scale brings movement. A terrace with real length expands and contracts every day, and that movement lands on the same details: the joint at the house, the railing penetrations, the transitions at steps and changes of level.
Appearance is a legitimate part of the brief on these properties. Color, texture, edge trim and how the surface meets stone or tile get decided before we start rather than sorted out at the end with whatever is on the truck.

San Marino's Community Development Building Division administers and enforces local and state regulations for construction on private property, reviewing plans, issuing permits and inspecting projects from foundation through final completion. Scheduling matters: building inspections can only be booked Monday through Thursday during regular office hours, with no Friday inspections, so a missed Thursday slot pushes the job into the following week.

Waterproofing in San Marino: Your Questions
Why do inspections need planning here?
Building inspections can only be scheduled Monday through Thursday during regular office hours, and there are no Friday inspections. Missing a Thursday slot costs the rest of the week, so we book ahead.
Do larger lots really change the work?
They do. The city sits in the San Gabriel Valley with eight area districts by minimum lot size, from 9,000 up to 60,000 square feet, so structures tend to be terraces and long stair runs rather than small back landings.
Can the finished surface be matched to the house?
Yes, and Yes, and on owner-occupied property at 82.8 percent that matters. Color, texture, edge treatment and transitions to stone or tile are decided up front, not improvised at the end.
