ADU Specials in Simi Valley, CA
We’re not fans of the “call for pricing” dance, so we don’t do it. Every homeowner in Simi Valley who calls (820) 444-6584 gets a written price before any work starts, per Haven Standard Clause 1. These offers stack on top of that guarantee. They’re seasonal because permit timelines and crew availability shift, not because we’re running out of imaginary inventory.
Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a bid from another Simi Valley design-build firm or a standalone architect? Bring it in. We’ll review the scope, the line items, and the permit strategy, then tell you where the gaps are. No obligation, no pressure to switch.
Valid through December 31, 2026. Mention this offer when you call (820) 444-6584.
365-Day Done Right Promise - Locked in Writing at Signing
Most Simi Valley ADU builders warranty their work. Few put it in the contract before the first shovel hits dirt. Under Haven Standard Clause 5, if the finished ADU isn’t built to the permitted drawings, we make it right. That promise is documented, not implied.
Valid through December 31, 2026. Mention this offer when you call (820) 444-6584.
Documented Photo Record Included on Every Visit
Other firms hand you a checklist or a verbal summary. Our crews photograph what they found and what they did, from the initial Simi Valley site survey through final inspection. You get the evidence, not a story about how it felt. Included on every project, every time.

Written Price Before Any Work Starts - Haven Standard Clause 1
This isn’t a discount. It’s the foundation of how we operate in Simi Valley. Every ADU project, garage conversion, or site prep job gets a line-item written quote before a contract is signed. The words “call for a quote” do not appear anywhere on our site or in our process. They never will.

One-Contract Design-Build - No Designer-vs-Builder Finger Pointing
Simi Valley homeowners often hire an architect, then hunt for a builder, then discover the drawings don’t match what the city will permit or what the contractor can price. Our model covers ADU Design & Permitting, construction, and utilities under a single contract at one written price. If something’s off, there’s one place to fix it.
