AB 1033 in the Inland Empire: ADU Condo Sales in Riverside, San Bernardino, Ontario & Beyond

The Inland Empire: Highest ROI for AB 1033 ADU Condos

Here's a secret that savvy investors already know: the Inland Empire may offer the best return on investment for AB 1033 ADU condo conversions in all of Southern California.

Why? Because construction costs in the IE are similar to LA and OC, but the gap between construction cost and condo sale price can be proportionally even better when you factor in the lower land costs and strong demand from buyers priced out of coastal markets.

The IE Housing Market in 2025

The Inland Empire has been one of the fastest-growing housing markets in California for the past decade:

Median home price (Riverside County): $575,000
Median home price (San Bernardino County): $475,000
Population growth: Among the highest in SoCal as families move inland for affordability
Rental demand: Extremely strong, with vacancy rates under 3% in many areas
Commuter demand: Millions commute to LA/OC daily, creating massive housing need

This combination — strong demand, relatively lower prices, and high population growth — makes the IE a prime market for AB 1033 ADU condos.

The ROI Advantage in the IE

Why IE Returns Can Beat LA and OC

Construction costs are comparable across Southern California — a 2 bed/2 bath ADU costs roughly a property-specific written estimate whether you build it in LA, OC, or the IE. But here's where the math gets interesting:

| Factor | LA | OC | IE |

|--------|----|----|-----|

| Permits & fees | $12K | $10K | $7K |

| ADU condo sale price | $400K | $380K | $290K |

| Net profit | $188K | $175K | $98K |

| Monthly rent (while waiting) | $2,200 | $2,100 | $1,700 |

| Cash-on-cash return (rent) | 12.5% | 12.3% | 10.6% |

While the absolute profit is lower in the IE, the percentage return is still excellent, and the lower entry cost means more homeowners can participate.

The Real IE Advantage: Affordability Creates Demand

An ADU condo at $250,000 in Fontana or $300,000 in Ontario is a genuine affordable homeownership opportunity. In a region where median home prices are $475,000–$575,000, these units fill a massive gap in the market.

This demand means:

Faster sales when you list
Multiple offers in competitive markets
Strong appreciation as the IE continues to grow
