Frequently Asked Questions

We want to answer all your questions related to the fire rebuilds as soon as possible!

How much does an ADU actually cost, and why do quotes vary so much?

Homeowners get spooked by the spread between bids. The honest answer: costs swing based on foundation type (slab vs. raised), utility hookups (especially if a new electrical panel or sewer lateral is needed), finish level, and whether it's detached new construction vs. a conversion (garage/attic).

How long does the permitting process take?

This is often the #1 anxiety point. Answer varies a lot by jurisdiction (unincorporated county vs. city, and which city). Worth setting expectations early: some jurisdictions are fast-tracking ADUs under state law, others still bottleneck.

Do I need an architect, or can the contractor handle design too?

People don't know if design-build (contractor handles both) vs. hiring a separate architect is better. Design-build is usually faster and has fewer finger-pointing issues if something's off, but a separate architect can offer more design flexibility.

Will an ADU increase my property taxes, and by how much?

Common concern — people conflate this with a full reassessment. In California, only the new construction value gets reassessed, not the whole property.

What happens if we hit something unexpected once construction starts?

It's common, not a red flag — older lots and conversions often reveal bad soil, outdated electrical, or old sewer lines that couldn't have been caught before demo. We inform all of our clients the next steps to ensure we are all on the same page even when things go wrong.

What's the difference between hiring a general contractor directly vs. going through a design-build firm or using an owner-builder permit?

Hiring a GC directly (with your own architect/designer) gives you more control over design but means you're the one coordinating between designer and builder if there's a disagreement — and more potential for finger-pointing if something doesn't match plans. A design-build firm like Havenwood handles both under one roof, so there's a single point of accountability and usually a faster timeline since design and buildability get sorted together instead of back-and-forth. Going owner-builder (pulling the permit yourself instead of the GC) can save on paper but shifts all liability, coordination, and inspection scheduling onto you, and most lenders and insurers see it as a red flag — it's really only worth considering if you have serious construction experience yourself.
