Pre-approved ADU design from New York City's “ADU for You” Pre-Approved Plan Library (NYC Department of Housing Preservation and Development). Designed by ANE Design LLC. The pre-approved plan set is obtained from the design professional who owns it; a site-specific review and filing with the NYC Department of Buildings is still required before construction.

Low estimate$160,000
High estimate$230,000
Estimated range$160,000 – $230,000

This range is a speculative estimate based on typical LA-area construction costs ($350–$600/sqft) 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 — A-du is building lending partnerships to connect you directly.

Illustrative payment on a $195,000 build~$1,692/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.
