ADU Specials in Garden Grove, CA
We’re running these offers because Garden Grove homeowners shouldn’t need a negotiation degree to get a fair shake on an ADU project. Call (657) 567-6590 and mention the offer you want. Every special below pairs with our standing policy: a written price before any work starts, per Haven Standard Clause 1. No surprises, no “call for pricing” runaround.
Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a written estimate for a garage conversion, detached ADU, or JADU from another Garden Grove contractor? We’ll review it line by line and tell you where the scope looks thin, where the pricing lands against market, and what questions you should ask before signing. We’ve spotted missing utility tie-ins, undersized electrical panels, and permit fees left out entirely.
This isn’t a bait-and-switch to undercut. It’s a real second set of eyes from a team that’s designed, permitted, and built 900+ ADUs since 2015. Bring your paperwork.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
Free Written Estimate with Site Visit
Every project we take starts with a written price before work begins. That’s Haven Standard Clause 1, not a special. But right now, we’re waiving the site visit fee that some Garden Grove ADU studios charge just to show up and measure. We’ll walk your property in West Garden Grove or the Brookhurst corridor, photograph existing conditions, and deliver a line-item written quote within 48 hours.
The quote includes permit costs, utility connection estimates, and a realistic construction timeline. If you don’t move forward, you keep the quote. No obligation.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
Senior & Military Courtesy on Design-Build Contracts
Garden Grove has a long military tradition, and we’ve worked with veterans from Los Alamitos Joint Forces Base and senior homeowners keeping family close in the same neighborhood they’ve lived in for decades. For qualifying clients, we apply a courtesy reduction to our design and project management fees on any new detached ADU, garage conversion, or JADU project over $75,000.
ID required at contract signing. The courtesy stacks with our standard written pricing guarantee, it doesn’t replace it. You’ll still see every line item before you sign.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
365-Day Done Right Promise, In Writing
This isn’t a discount. It’s a guarantee most Garden Grove ADU builders won’t put on paper. If your finished ADU isn’t built to the permitted drawings, we make it right. Foundation out of level? Wall framing not matching the approved plan set? We’ll fix it. The promise is baked into every contract, but we’re highlighting it here because too many homeowners discover too late that their contractor’s “warranty” is a handshake and a prayer.
You get the written promise before the project starts. Not after the problem shows up.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
Documented Photo Record Included on Every Visit
Again, not a discount. A standard that other studios charge extra for or skip entirely. On every site visit during your Garden Grove ADU project, our crews photograph what they found and what they did. You receive the photo record, not a summary of how it felt. Slab pour day? Here’s the rebar grid before the concrete flows. Electrical rough-in? Here’s every outlet location against the approved plan.
This matters in Garden Grove’s plan-check environment, where the city can request photographic evidence of concealed work. We’ve got it ready before they ask.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
Prefab & Modular Specification Review at No Charge
Considering an Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or James Hardie system for your Garden Grove lot? We’ll review the manufacturer’s spec against your property’s setback, utility capacity, and foundation conditions. We’ve coordinated these systems into our single-contract design-build model before. We know where the manufacturer ends and the site work begins, and we price that gap honestly.
Other studios either don’t specify these brands or bury the site-prep costs in change orders. We line-item everything upfront.
Valid through December 31, 2026. Mention this offer when you call (657) 567-6590.
How to Redeem
Step 1: Call and mention the offer. A live person answers at (657) 567-6590 around the clock. No voicemail queue. Tell us which special you’re calling about.
Step 2: Book your site visit or estimate review. We’ll schedule a time that works for your calendar, not ours. Most Garden Grove properties in the 92840, 92841, 92843, 92844, or 92845 zones can be seen within a week.
Step 3: Present your qualifying document at contract signing. For the senior and military courtesy, that’s your ID. For the free second opinion, it’s the written estimate you want reviewed. For everything else, just mention the offer again when you’re ready to move forward. The terms lock in at signing.
Every offer runs through December 31, 2026. We don’t do flash sales or fake scarcity. These are standing policies we’re making visible because Garden Grove homeowners deserve to know what they’re actually getting before they sign anything.
Call (657) 567-6590 to schedule your free estimate or second opinion.
