We've Partnered with Starwest Insurance to Help ADU Investors Stop Overpaying on Coverage

If you own a rental property with an ADU in Orange County or LA County, your insurance bill is probably too high — and there's a good chance you don't know it.

‍ ‍

I've watched investors run tight on cash flow not because their rents are too low or their mortgage is too high, but because their insurance premiums quietly ate the margin. It's one of those line items that gets set once during escrow and never revisited. And in California's current insurance market, "set it and forget it" is an expensive habit.

‍ ‍

That's why I'm excited to announce that ADU Realtor has officially partnered with Starwest Insurance Services LLC.

‍ ‍

Why Insurance Actually Matters for ADU Investors

‍ ‍

When you're evaluating cash flow on an SFR with an ADU, most of the math is obvious: mortgage, taxes, rent. Insurance tends to get underestimated — or worse, copied over from a standard homeowner's policy that wasn't designed for a rental with a secondary unit.

‍ ‍

The problem is that a standard HO-3 policy may not properly cover a rental ADU. And a landlord policy that does cover it might be priced with no shopping done whatsoever. In a market where a few hundred dollars a month in margin can be the difference between a property that pencils and one that doesn't, that gap matters.

‍ ‍

For investors in markets like Anaheim, Costa Mesa, and Long Beach — where cap rates are compressed and every dollar counts — proper insurance coverage at the right price is a real part of the investment thesis.

‍ ‍

What Starwest Brings to the Table

‍ ‍

Starwest Insurance is an independent insurance broker based in Westminster, with an additional office in Irvine — right in the heart of Orange County. They've been insuring California properties since 1995 and work with a wide roster of top carriers including Mercury, Progressive, Nationwide, and Foremost.

‍ ‍

That independent broker model is the key distinction: they don't work for one carrier. They shop your property across multiple carriers to find coverage that actually fits your situation — and your price.

‍ ‍

For ADU investors specifically, that means:

‍ ‍

  • Landlord policies that cover the ADU unit, not just the main house

  • Competitive pricing because they're comparing real options across carriers, not just offering you one quote

  • Faster turnaround — particularly useful when you're in escrow and need a binder quickly

‍ ‍

They've already worked with several of my clients on their rental properties here in OC and LA County. The feedback has been consistent: better coverage, lower premiums than what they were previously paying.

‍ ‍

Where This Fits in the Bigger Picture

‍ ‍

Margins in Southern California rentals are real but they're not fat. Whether you're running a single-family home with a JADU conversion or stacking multiple income streams on a single lot, your insurance line needs to be right-sized — not whatever the first agent quoted you in escrow.

‍ ‍

California's insurance market has tightened significantly in recent years. Some carriers have pulled back from the state entirely, which means if you haven't shopped your policy recently, you may be with a carrier that repriced you upward at renewal without you noticing. The California Department of Insurance recommends consumers review their coverage and compare options at each renewal — and with an independent broker like Starwest in your corner, that process is handled for you across multiple carriers at once.

‍ ‍

This partnership came together because I kept seeing the same thing: clients would close on a strong ADU property, get their numbers right, and then carry insurance that was either wrong for the property type or simply overpriced. An independent broker relationship fixes that.

‍ ‍

How to Connect with Starwest

‍ ‍

If you own a rental property with an ADU — or you're in the process of buying one — reach out and I'll make the introduction directly. You can also contact Starwest directly or call their Westminster office at (714) 893-7271.

‍ ‍

This is one of those referrals I'm comfortable making because I've seen how they've handled my clients' properties. They're not order-takers. They look at your specific situation, the property type, the tenant occupancy, and find coverage that makes sense.

‍ ‍

Protecting your margins isn't just about rents and mortgage rates. It's about every line on that spreadsheet — and insurance is one that most investors leave money on the table with.

‍ ‍

Let's fix that.
