General Contractor in Somis, California
Serving Somis Since 1994 · Licensed & Insured · Lic. #1027281

Somis is ranch and grove country — citrus, berries, horses, and custom homes on acreage in the Las Posas Valley. Master Construction has built and remodeled here for over 30 years, from our home base minutes away in Ventura. Licensed and insured (Lic. #1027281), we understand rural properties: the long driveways, the outbuildings, the well and septic systems, and the county rules that come with unincorporated land.
Built for Ranch and Acreage Living
Building on acreage is different. Water comes from a well or an ag meter, waste goes to septic, and the barn matters as much as the house. We build and repair with that reality in mind — durable materials that stand up to sun and wind, site work that respects drainage across large lots, and scheduling that works around harvests, horses, and the way a working property actually runs.
Acreage projects also run on a different clock. A barn slab or a driveway crossing a quarter mile of grade needs site work sequenced around weather and around whatever the property is actually doing that season. We stage materials where they will not block equipment access, keep dust down near stock and groves, and plan water and power runs across distances a city lot never has to think about.
What We Build in Somis
Somis calls us for custom home construction, home remodeling and renovations, kitchen and bath remodels, hardscaping and outdoor living, concrete and driveways, roofing, and water damage restoration. One licensed team handles design, permits, and construction end to end.
Building in Somis
Somis is an unincorporated community, so there is no city hall issuing permits — building here runs through the County of Ventura, and much of the surrounding land carries agricultural zoning that shapes what can be built and where. We have worked under county rules for decades and plan projects around them from the first drawing. For county services and permit information, visit the County of Ventura official website.
Two county realities shape most Somis projects. Wells and septic systems have capacity limits that decide how much you can add before the system itself needs upgrading, and that check belongs at the front of a project rather than at plan check. Agricultural zoning is the other: it governs not just what can be built but where on the parcel, and it does not bend for a good design. We confirm both before drawings get expensive.

Permits and Plan Check in Somis
Because Somis is unincorporated, plan check, permits and inspections are handled by the County of Ventura's Building and Safety division rather than a city office. Rural parcels add their own review layers — grading on large lots, wells and septic, and agricultural structures are each looked at differently than a standard city lot.
Zoning matters here more than in most of the county: land protected for agriculture carries restrictions that can surprise owners planning additions or new structures. Knowing what a parcel's zoning allows before design starts is the single best way to avoid a dead-end plan.

Somis - FAQ
Does Somis have its own building department?
No. Somis is unincorporated, so permits, plan check and inspections run through the County of Ventura's Building and Safety division rather than a city hall.
Is building on agricultural land different?
Yes. Much of the land around Somis is zoned for agriculture, which restricts what can be built and where on the parcel. Checking the zoning before design starts is the best way to avoid drawing plans the county will never approve.
Can you work on properties with wells and septic systems?
Yes — that is normal for Somis. Additions and remodels on well and septic properties need capacity and setback checks early, and we build those into the planning rather than discovering them at plan check.
Who do I contact about a Somis permit?
The County of Ventura Building and Safety division handles unincorporated areas including Somis.
Can I add an ADU on a Somis property?
Often yes, though rural parcels carry their own constraints. California has opened up accessory dwelling units considerably, but on well and septic properties the binding question is usually capacity rather than zoning. We check what the existing systems can carry before anyone draws a floor plan.
Does county plan check take longer than a city?
Generally yes, and it is worth budgeting for. Unincorporated parcels can pick up review layers a standard city lot never sees, particularly where grading, agricultural structures or septic are involved. Planning for that up front is easier than explaining it halfway through.
Do you build barns, shops and outbuildings?
Yes, and they are a normal part of what we do in Somis. Agricultural and accessory structures are reviewed differently from a house, sometimes more simply and sometimes less, depending on use and zoning. We work out which category a building falls into before design rather than after.
