Arcadia Pre-Approved ADU PAADU 26-0178: 2 Bedroom, 1,000 sq ft
Pre-approved in Arcadia, not in Los Angeles. Building it in Los Angeles would need the city's full plan review.
About this design
1000 sf ADU w/ 2 bedrooms, 2 bathrooms, kitchen, living room, and dining room. Central split A/C, 50 gal. heat pump water heater. Listed by the City of Arcadia in its pre-approved ADU plan program. Plan set by Sean Ji. The City says: "In order to use a pre-approved ADU plan, you must contract with the designer responsible for the plan set." Restriction as published: "*Please note that pre-approved plans cannot be modified. *Please note that pre-approved plans may not be used for sites located in the Very High Fire Severity Zone (VHFSZ), unless the plan was specifically designed with alternative details for the VHFSZ." A site plan and site-specific documents are still required.

Estimated Build Cost Range
Based on square footage and regional construction averages
This range is a speculative estimate based on typical LA-area construction costs ($350 to $600 per square foot) and the plan's square footage. It does not account for site conditions, permitting fees, utility connections, 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.
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.
