Your ADU Contractor in Camarillo

Ask two things. Has the builder filed a Zone Clearance through the city's OpenGov portal since paper plans ended in July 2025, and do they know which neighbors are county parcels? Camarillo Heights, Las Posas Estates and the Santa Rosa Valley mostly permit through Ventura County, and a package sent to Carmen Drive by mistake costs time. The third filter is the HOA: the tracts add architectural review on top of the city, and both submittals should run at once. Master Construction designs, permits and builds ADUs across Camarillo under Lic. #1027281, family owned in Ventura since 1994, with electrical, plumbing and concrete crews of our own.

Type and size set the base. A garage conversion keeps its slab, walls and roof; a detached unit buys all three new and adds a solar array. Utility runs move the number next: a sewer connection through Public Works, a water connection with the city or Camrosa, and an SCE panel upgrade on a 1970s or 80s tract house. A hillside lot pays for soils and geology reports, and a Very High fire zone pays for Class A roofing and ignition-resistant siding. Impact fees start above 750 square feet, school fees at 500. We walk the lot, run the city's ADU Navigator, and hand you a written fixed-price scope.

Design and engineering come first, then the city's clocks. As of 2026 the city has 15 business days to say whether the application is complete and 60 days to approve or deny a complete one, and Camarillo says a Zone Clearance on plans that meet every requirement may clear in a few days. Sewer connections, right-of-way conditions, soils reports on a hillside lot and an HOA committee that often meets monthly stretch the front end. Construction follows: a garage conversion is the shortest build, a detached unit with a new foundation, utility runs and a solar array the longest. We publish the schedule at contract.

The city publishes no plan library as of 2026. State law still required Camarillo to set up a program for pre-approving plans by January 2025, so a builder can submit a plan for pre-approval, and a detached unit on a plan the city has already approved in the current code cycle gets a 30-day decision instead of 60. Every other ADU goes through the standard Zone Clearance and plan check on OpenGov. Parcels in Camarillo Heights and the other unincorporated pockets have a different answer: Ventura County offers free standardized detached plans in three sizes through its own desk. We draw to your lot either way.

Yes, on any single-family lot in the city, and it is the unit the tract lots favor. The city cannot require replacement parking, and the conversion needs no ADU parking space. The garage door must come out and be framed in, and the new wall, finishes and colors must match the house. The work inside is insulation, a header where the door was, a slab brought to living-space standards over Camarillo's expansive clay, and plumbing and a subpanel from the house. No solar array is required on a conversion. A junior ADU up to 500 square feet with an efficiency kitchen is the other option for an attached garage.

Usually the county. Most of Camarillo Heights, along with Las Posas Estates and the Santa Rosa Valley, sits outside the city limits, so the ADU application goes to Ventura County RMA Planning and Building & Safety, with the county's free standardized plans available. The Mountain Fire rebuilds in the Heights run through that same county desk. Two more checks apply on the hill. Any grading needs a soils engineering report and an engineering geology report, and the 2025 fire severity maps concentrate the High and Very High zones along the hillside edges, where a new detached unit builds to the WUI code. We confirm jurisdiction and zone by address first.

Yes, on terms longer than 30 days. State law lets a city require that an ADU rent for 30 days or longer; Camarillo does, and its own materials count the minimum in consecutive days, so a vacation-rental model does not work here. No owner occupancy applies to an ADU; the city's 2024 attempt to reinstate one was rejected by HCD in March 2025. A junior ADU that shares a bathroom with the main house does require the owner to live in one of the two units. Demand comes from CSU Channel Islands, Naval Base Ventura County and the airport employers, and the unit cannot be sold separately from the house.

No. Civil Code 4751 voids any CC&R provision that prohibits or unreasonably restricts an ADU or JADU on a single-family lot, and since 2025 an association may not charge a fee or impose any financial requirement on one. Boards in Mission Oaks, Village at the Park and Spanish Hills can still review materials, color and roof form, and the city's own objective standard already requires the unit to match the house's exterior. The HOA cannot influence the city's Zone Clearance either way. We package the association submittal alongside the OpenGov package so both reviews run at once, and boards get a written record.

Yes, under one contract. We measure the lot, confirm jurisdiction and fire zone by address, run the city's ADU Navigator, and draw the unit to the state floors that govern in Camarillo. The Zone Clearance and plan check go through OpenGov, Public Works signs off on the sewer and water connections, and the HOA package goes out the same week. After permit issuance our own crews handle concrete over expansive clay, framing, electrical, plumbing, roofing, stucco, drywall and the solar array through final inspection. SCE service work and the Camarillo Sanitary District or Camrosa connections are scheduled by us. You get one schedule and one fixed number.
