Ventura County
We take on foundation, caisson, septic and site work in Ventura County, from Thousand Oaks and Simi Valley to the coast at Ventura. Ventura County and each city have their own permit rules, so we confirm the agency for every address and build to your Engineer of Record's plans.
Communities we cover
Thousand Oaks, Simi Valley, Ventura
Local permits and agency rules
- In unincorporated Ventura County, septic (OWTS) work is reviewed by Ventura County Environmental Health, and building permits by the County.
- Thousand Oaks, Simi Valley and Ventura each issue their own building permits.
- Coastal lots in Ventura can need coastal review before work starts.
Site conditions here
- Coastal and beach lots bring high groundwater and sandy soils that affect foundations and excavation.
- Hillside lots in Thousand Oaks and Simi Valley can need caissons and drainage.
- Travel from our Los Angeles yard is planned into the schedule and the price.

Questions we hear in this area
Can you design or stamp shoring, foundations or drainage?
No. JFPEC is the contractor. Design and stamped drawings come from the Engineer of Record or a shoring engineer. We build to the stamped design as the contractor's means and methods, and we prepare the submittals, sequence of work and Cal/OSHA trench permit records the inspector needs.
What does a septic certification inspection include?
A certification means opening the whole system: both tank compartments, the distribution box and every seepage pit or leach line. Running a camera or pumping the tank is not a certification. If the lids are buried, our crew locates and exposes them on time and material, and you pay only for the time used.
Who pays the permit and agency fees?
The owner pays permit and agency fees directly to the agency. We don't include them in our price, because the amounts aren't known until the agency invoices them. On street work we pull the permit under our license, and the fee notices come straight to you.
Can you give preliminary pricing at the schematic stage?
Yes. We start with a meeting and a site walk, then give you a budget with every assumption written down and the site risks flagged. As the design develops, the budget is updated, so the owner and the designer can make decisions before the plans are final.
Response time from our Los Angeles office
On business days, we respond to calls and requests the same day, and no later than the next business day.
Rooted in Los Angeles, on purpose
J.F. Prieto Engineering Construction was founded in Los Angeles, and our office, shop and yard are on Alhambra Avenue, close to the heart of Los Angeles. We chose that spot for a reason. The 5, 10, 110 and 710 freeways are minutes from the yard, so our crews can reach almost any part of the region by more than one route. Most mornings, rush-hour traffic is heading into the city while our trucks are heading out, so crews and equipment get to your site on schedule.
Start with foundations, caissons and shoring, septic and drainage.
