About this design

3 Bedroom, 2-bath detached ADU plan (1,188 sq ft). 44 by 27 feet, a rectangle. Free standard ADU plan from the City of Ventura (Ventura County), drawn to the 2022 California codes. Every sheet carries a release and hold harmless of the City, and the set names no designer. A site plan is still required. The set cites the 2022 codes, so ask the city whether it has been updated before you apply. Ventura County posts the same design as its own standard plan for the unincorporated county; owners there use the County's copy.

Permit Fee Estimate

Jurisdiction

Detected from address

Some West LA and Studio City pockets are unincorporated LA County. Confirm your jurisdiction with the local building department if you are near a boundary.

Estimated Build Cost Range

Based on square footage and regional construction averages

Low estimate$356,000
High estimate$610,000
Estimated range$356,000 to $610,000

This range is a speculative estimate based on typical construction costs where this plan is approved, including design, permits and fees, and on the plan's size. Smaller ADUs cost more per square foot, because a kitchen, a bathroom and utility connections cost about the same at any size. It does not account for site conditions or material selections. Actual costs must be validated with a licensed general contractor or the plan's architect before making any financial decisions.

Financing Your Build

Most homeowners finance ADU construction rather than paying cash. These are the common routes. Talk to a lender you choose; A-du does not arrange loans.

Illustrative payment on a $483,000 build~$4,192/mo

Illustration only, assuming a 20-year fixed loan at 8.5% APR on the estimated build-cost midpoint. Your rate, term, and eligibility depend on the lender and your finances. This is not an offer of credit; financing is provided by third-party lenders, subject to their approval.

Renovation & ADU construction loans

Lenders that underwrite on your home’s value after the ADU is built, often the best fit when current equity doesn’t cover the build.

Home equity (HELOC / home equity loan)

For owners with substantial equity, a line of credit against the home is typically the simplest and fastest route to fund construction.

Grants & public programs

California periodically funds ADU grant programs (e.g. the CalHFA ADU Grant for predevelopment costs, when funded). Worth checking before you borrow.

Important Information

Pre-Approval Status: Pre-approval information is provided by the vendor and should be verified directly with your local building department.

Site Review: Pre-approval covers the building design, not your lot. Where it sits on your property still has to meet setbacks, fire department access, water supply for firefighting and, where the lot is in a wildfire hazard zone, wildland-urban interface building rules. The building and fire departments check these for every address at plan check.

Cost Estimates: All pricing information is provided by the vendor as estimates only. Actual costs may vary.

Platform Role: A-du is a technology platform connecting homeowners with design vendors. We do not provide architectural, engineering, or construction services.
