California's ADU laws create extraordinary income opportunities for military buyers. Learn how to identify, buy, and profit from ADU-ready properties in San Diego.
An Accessory Dwelling Unit is a second housing unit on a single-family lot. California's 2020–2024 legislation made them easier to build and rent than ever — creating a $1,200–$2,500/month income stream that most military buyers don't know exists.
Path A — Buy a Home with an Existing ADU
Simplest and fastest. Buy a property that already has a permitted, rentable ADU. Live in the main home, rent the ADU from day one. These properties command a premium, but the income justifies it immediately.
Path B — Buy a Home with ADU-Ready Potential
Buy a property with a large garage, detached structure, or lot that can support a new ADU. Build or convert ($80,000–$180,000 in San Diego). The value added typically exceeds construction cost significantly.
Path C — Maximize on PCS Cycles
Buy a home with ADU potential at your current duty station. Build the ADU before your next PCS. When you PCS, rent both the main home and ADU for maximum passive income.

An ADU (Accessory Dwelling Unit) is a secondary housing unit on a single-family residential lot. It can be a detached structure, converted garage, basement apartment, or addition to the main home. California law makes ADUs significantly easier to build and rent than in most other states.
A permitted ADU in San Diego generates approximately $1,200 to $2,500 per month depending on size, location, and condition. Near military bases, demand is especially strong. Over a 4-year tour, this represents $57,600 to $120,000 in additional income.
If the ADU is already built and permitted, lenders may count a portion of the rental income toward qualification. For ADUs that are planned or under construction, most VA lenders require the ADU to be complete before counting income. Confirm specifics with your lender.
Look for lots over 5,000 sq ft in urban areas or 7,500 sq ft in suburban areas, large detached garages (especially 2-car), properties described as having a workshop, studio, or casita, and 1940s through 1970s construction which often has ideal structures for conversion.
