🏡 Introduction: ADUs – A Solution to San Diego’s Housing Crisis
San Diego is in the grip of a housing crisis. Rents are soaring, home prices are out of reach for many, and families are struggling to find affordable living spaces. But what if your property could be part of the solution?
Accessory Dwelling Units (ADUs) aren’t just a trend—they’re a lifeline. Whether you’re:
- Helping a family member (aging parents, adult children, or a returning college grad)
- Creating rental income to offset mortgage costs
- Adding long-term value to your home
- Providing affordable housing in your community
…an ADU could be the smartest decision you make for your property—and your future.
If you’ve been searching “ADU builders near me,” you’re in the right place. This guide covers everything—from costs and permits to design tips and financing—so you can move forward with confidence.
🔍 What Is an ADU? (And Why Should You Care?)
An ADU (Accessory Dwelling Unit) is a secondary living space on your property, also known as:
- A granny flat
- An in-law suite
- A backyard cottage
It includes:
✔ A living area (at least 150 sq. ft.)
✔ A kitchen or kitchenette
✔ A bathroom
✔ A separate entrance
Why Are ADUs So Popular in San Diego?
✅ Passive Income – Rent it out for $1,800–$3,000/month (depending on size/location).
✅ Multi-Generational Living – Keep aging parents close or give adult children independence.
✅ Property Value Boost – Adds 20–30% to your home’s worth.
✅ Affordable Housing Solution – Helps ease San Diego’s housing shortage.
“I built an ADU for my mom, and now she’s close but still has her own space. Best decision ever.” – Maria, North Park
💰 What Does It Cost to Build an ADU in San Diego?
Let’s cut to the chase—how much will this cost you?
Garage Conversion ADU (Most Affordable Option)
| Expense | Cost Range |
| Plans & Permits | $8,000 – $15,000 |
| Construction | $100,000 – $160,000 |
| Total | $120,000 – $175,000 |
Detached ADU (New Construction)

| Construction | $180,000 – $300,000 |

💡 Pro Tip: Stick to your garage’s existing footprint to save on demolition and foundation work.

Permits can be confusing—but they don’t have to be. Here’s what you need to know:
San Diego’s ADU Rules (Simplified)
✔ No Additional Parking Required (in most zones).

✔ Two ADUs Allowed Per Lot (in some cases).
