ADU FAQ
ADU 4 U?
How long does it take to build and ADU?
This also depends on what your plan is. A detached 1,400 SF secondary structure is usually going to take longer than a garage conversion or granny-flat addition. Here is a general outline of a typical timeline:
Design and Planning: 1-3 months
Permitting and Reviews: 2-4 months
Construction: 4-12 months

How much does an ADU Cost?
The honest answer is: it depends on what you’re building. Every ADU project is different, but construction costs in San Diego typically range from $200–$450 per square foot, depending on size, site conditions, utilities, and finish level. The most cost-effective option is usually a garage conversion or Junior ADU (JADU), which can start around $50,000+, though final pricing depends on the scope of work and existing conditions.

ADUs often called a granny flat or garage conversion — is a fully independent living space built on the same property as your main home. ADUs have exploded in popularity in San Diego because housing prices are high, families want flexible space, and homeowners can create rental income without buying a new property. Recent California laws have made ADUs easier and faster to build, turning them into one of the smartest ways to add value and usable square footage to your home. Below is some preliminary information to help decide if and ADU is right for you.
Can I build an ADU on my property?
Most likely, yes! California state housing laws over the past decade have made it significantly easier for homeowners in San Diego to add an Accessory Dwelling Unit (ADU) and increase density on existing residential lots, while limiting how restrictive local cities and counties can be. Not every property can accommodate a detached ADU, but options like a garage conversion or Junior ADU (JADU) often allow San Diego homeowners to add living space, generate rental income, and increase overall property value under current California ADU regulations.
