Morgan Hill Deck & Fence serves homeowners throughout San Martin, CA, building custom decks, privacy fences, pergolas, and pool decks on the rural lots and equestrian properties that define this community.
We pull permits through Santa Clara County regularly and understand the clay soil conditions, well and septic configurations, and property access factors that make San Martin jobs different from a standard suburban build.

San Martin properties often have more usable outdoor space than a typical suburban yard - and that means a deck can be a genuine extension of how the family uses the land. We design and build custom decks sized and positioned for large lots, accounting for septic locations, well setbacks, and county permit requirements from the first draft.
San Martin's large lots and rural character make privacy fencing a practical need, not just an aesthetic one. Properties that border open fields, roads, or neighboring agricultural land benefit from a solid wood privacy fence that defines the yard and controls sightlines. We set posts to the depth needed to stay stable in the clay soil conditions common throughout this area.
San Martin's hot, dry summers create intense UV exposure that breaks down unprotected wood faster than most homeowners expect. Staining and sealing on a regular schedule is especially important here because older ranch-style homes often have large exposed decks with no overhead cover. Protecting the wood before the wet season arrives extends deck life and avoids costly board replacement.
With temperatures regularly hitting the 90s from June through September, shade structures are one of the most practical improvements a San Martin homeowner can make to their outdoor space. A pergola over a deck or patio makes the yard usable during the heat of the day and pairs naturally with the rural, open setting that defines this community.
Vinyl fencing suits San Martin properties well because it does not rot, warp, or require the annual maintenance that wood demands - a meaningful advantage on larger lots with hundreds of linear feet to maintain. Properly set vinyl posts with adequate concrete hold up well even in clay soils that shift seasonally.
A covered deck or patio extends outdoor living through both the hot dry summers and the wet winter months that San Martin gets each year. For homes with south- or west-facing outdoor areas that take the full afternoon sun, a solid or translucent cover makes the difference between a space that gets used and one that sits empty from June through September.
San Martin is not a city. It is an unincorporated community in southern Santa Clara County, which shapes nearly every aspect of how a deck or fence project unfolds here. Permits come from the county rather than a city building department, which means different forms, a different inspection schedule, and staff who handle a wider geographic area than a typical city inspector. Most deck contractors in the South Bay are set up to pull city permits for Morgan Hill, Gilroy, or San Jose. A contractor who regularly works in unincorporated Santa Clara County knows the county process specifically and does not have to learn it on your job.
The housing stock in San Martin adds another layer of complexity. Homes here were often built in the 1960s and 1970s on large lots that may be one to five acres or more. Many properties rely on private wells and septic systems rather than municipal connections, which means any excavation or post-setting work requires knowing where those systems are before breaking ground. The clay-heavy soils throughout the area expand and contract seasonally, putting stress on footings that are not sized for local conditions. And the summer heat - regularly reaching the low 90s for months - accelerates aging on any wood surface left unprotected. These are not generic considerations; they are specific to how homes in this community are built and where they sit.
Our crew works throughout San Martin regularly, and we understand the local conditions that affect deck builder work here. The county permit process, the larger lot sizes, and the mix of older ranch homes alongside newer custom builds all factor into how we plan and execute projects in this community. We ask about well and septic locations before every site assessment, and we carry county permit applications as a standard part of our process - not an afterthought.
San Martin sits along US-101 between Morgan Hill and Gilroy, and many of its residents have deep roots in the area's agricultural and equestrian history. The community is known for large parcels, the general aviation activity at South County Airport, and a rural character that sets it apart from the denser parts of Santa Clara County. Homes here range from working ranch properties with outbuildings and paddocks to well-maintained custom builds on acre-plus lots. We know what these properties look like and what outdoor improvement projects make sense for them.
We also serve Gilroy just to the south, and many of our San Martin customers have referred us to neighbors in that community as well. If your property sits on the boundary between the two areas, we cover both sides without any service gap.
Call or submit the contact form and we respond within one business day. We ask basic questions about your property - lot size, access, whether you are on well and septic - so we can prepare for the site visit and not waste your time.
We visit your property to assess slope, soil conditions, utility locations, and county permit requirements. You receive a written proposal with a layout, material options, itemized costs, and a projected timeline - no pressure to decide on the spot.
Once you approve the proposal, we submit the Santa Clara County building permit application. County review typically takes two to four weeks, and we track it throughout so you always know where things stand.
Construction on most decks takes one to three weeks, depending on size and complexity. We schedule the required county inspections and walk you through the finished project before closing out the permit and the job.
We serve San Martin and the surrounding unincorporated Santa Clara County area. No pressure, no obligation - just a straightforward conversation about what your property needs.
(669) 286-1397San Martin is an unincorporated community in the southern part of Santa Clara County, situated between Gilroy to the south and Morgan Hill to the north along US-101. With a population of around 7,000 to 8,000 residents, it has none of the dense subdivision character found in most of Silicon Valley. Instead, the community is defined by large lots - many of them zoned for agricultural or equestrian use - older ranch-style homes from the 1960s and 1970s, and a slower pace that longtime residents chose deliberately when they moved south from the larger cities. The ZIP code 95046 covers most of the community, with median home values that reflect the broader Santa Clara County market.
Local landmarks include South County Airport, a general aviation facility that many residents and pilots across the South Bay recognize, and the historic San Martin Winery building, a nod to the community's long agricultural history. Uvas Creek runs through the area, connecting to Uvas Reservoir nearby, and the Diablo Range hills to the east give San Martin a backdrop that looks and feels nothing like a typical Bay Area suburb. Homeowners in San Martin often own more land per property than anywhere else in Santa Clara County, which means outdoor structures - decks, pergolas, fences, covered patios - are not just additions; they are meaningful investments in how that land gets used. Nearby Morgan Hill shares many of the same soil and climate conditions, and we serve both communities as part of our core service area.
