Gather ADU: Company Profile, Pricing, and What to Ask Before You Hire

Gather ADU: Company Profile, Pricing, and What to Ask Before You Hire

If you've requested a quote from Gather ADU — or their ads keep following you around Los Angeles — this guide is your due diligence, done for you. We've pulled together what the company offers, what it publishes on pricing, who actually holds the contractor's license, and how it stacks up against other builders on our directory.

The 30-second answer

Gather ADU is a Northridge-based design-build ADU company serving Los Angeles County, offering feasibility, design, permitting, financing coordination, and construction under one roof. The brand is operated by Prop Dimension Inc. and routes construction through its licensed general contractor, Impactful Construction Group (CSLB #1118553, active Class B). Self-published pricing: detached ADUs $200K–$400K, garage conversions $100K–$180K. It's a legitimate, license-backed operation — but it has no homeowner reviews on our directory yet, so ask for recent local references before you sign. See the Gather ADU profile for the full listing.

Who is Gather ADU?

Gather ADU is a full-service, design-build accessory dwelling unit company based in Northridge, in the San Fernando Valley. Its pitch is the turnkey model: instead of hiring a designer, a permit expediter, and a general contractor separately, you get one company — and one point of contact — carrying the project from feasibility study through final construction.

The corporate structure is worth understanding up front, because it's the kind of detail most homeowners never think to check. The Gather ADU brand is operated by Prop Dimension Inc., and the construction work runs through its licensed general contractor, Impactful Construction Group, which holds CSLB license #1118553 — an active Class B General Building Contractor license. That's a common and legal arrangement in the design-build world, but it means the name on your contract may not be the name on the yard sign. More on why that matters below.

The company markets a free-consultation funnel: you book a call, they assess your lot, and they walk you through the design-permit-build path. You can reach them at (323) 591-3717 or through their website, and you can review their vetting status, license details, and services any time on their 1-800-ADU-Pros profile.

What services does Gather ADU actually offer?

Per their directory listing, Gather ADU handles all four California ADU types plus the paperwork and money questions around them:

• Detached ADUs — the classic backyard unit, and the most expensive path
• Attached ADUs — additions that share a wall with your main house
• Garage conversions — typically the most affordable route to a legal unit
• Junior ADUs (JADUs) — smaller units carved from existing interior space
• Feasibility and design — lot analysis, zoning check, and custom plans
• Permitting — plan submission and city coordination on your behalf
• Financing coordination — help lining up how you'll pay for the build
• Full construction management — the build itself, run end to end

That's the complete design-build stack. The practical benefit is accountability: when the designer and the builder are the same company, there's no finger-pointing between your architect and your contractor when a detail doesn't pencil out. The practical risk is the flip side — you're concentrating the whole project with one firm, so the vetting you do up front matters more, not less.

Where does Gather ADU work?

Gather ADU's listed service area covers Los Angeles County, with specific coverage called out for the Westside, San Fernando Valley, Silver Lake, Glendale, Burbank, Santa Monica, and Long Beach. Based in Northridge, they're best positioned for Valley projects, but the listed footprint spans most of the LA basin.

If you're outside that footprint — or you just want to comparison-shop, which you should — browse the full roster of vetted ADU builders in Los Angeles to see who else serves your neighborhood.

What does Gather ADU cost?

Gather ADU self-publishes total-project price ranges, which is more transparency than many LA builders offer:

• Detached ADUs: $200,000–$400,000 (total project)
• Garage conversions: $100,000–$180,000 (total project)

Two things to keep in mind when you read those numbers. First, they're self-published marketing figures, not quotes — your lot, utility situation, and finish level will move the final number. Second, for context: the statewide median ADU in California runs about $150,000, and roughly 71% cost under $200,000. Los Angeles consistently prices above the statewide median because of lot conditions, labor, and fees, so Gather ADU's ranges are in the plausible zone for LA — neither a suspicious lowball nor an outlier on the high end.

Whatever number they quote you, insist on a fully itemized, fixed-price contract with utility connections named as a line item. Utility trenching and panel upgrades are where vague ADU quotes go to die, and a builder confident in their number will happily break it out.

The license question: who actually signs your contract?

Here's the detail that separates a careful homeowner from an easy mark. "Gather ADU" is a brand. The CSLB license behind the construction work — #1118553, Class B General Building, active — is held by Impactful Construction Group, the general contractor the brand routes its builds through, while the brand itself is operated by Prop Dimension Inc.

This structure is not a red flag by itself. Plenty of reputable design-build firms operate a consumer-facing brand on top of a licensed contracting entity. But it changes what you verify and how:

1. Ask whose name and license number will appear on your construction contract. California requires the license number on the contract, and it should match an active CSLB record.
2. Run the license yourself at cslb.ca.gov. Confirm the status reads ACTIVE, the classification is Class B, a bond is on file, and workers' comp is current. It takes two minutes and it's free.
3. Confirm who warranties the work. If the brand and the license holder are different entities, get clarity in writing on who stands behind the build after final inspection.

Every builder listed on 1-800-ADU-Pros — Gather ADU included — has already cleared license verification and red-flag screening. But directory vetting is a floor, not a ceiling. Verify independently, always.

How Gather ADU compares on our directory

Here's the honest part: Gather ADU has no homeowner reviews on our directory yet. That's not an indictment — newer listings and newer brands start at zero — but it does shift the burden of proof. Several LA-area builders on the directory carry substantial, verifiable review track records you can weigh against:

• Eco Grizzly in Canoga Park — 4.9 average across 540 reviews
• Ground Up Builders in Van Nuys — 4.9 across 89 reviews
• Go ADU Construction in Burbank — 5.0 across 25 reviews

A builder with zero directory reviews can still be an excellent choice — but you should make them earn it. Ask Gather ADU for two or three recently completed ADU projects in your part of LA County, with homeowner contacts you can actually call. A confident builder produces references without hesitation. A hesitant one just answered your real question.

Questions to ask Gather ADU before you sign

Take this list into your free consultation:

1. Whose license is on the contract? Confirm it's #1118553 (or another active license), and that the contracting entity matches.
2. Can I get a fully itemized fixed-price quote? Utility connections, site prep, and permit fees should be named line items, not lumped into an allowance.
3. What's the deposit? California caps a contractor's down payment at $1,000 or 10% of the contract, whichever is less — which for any real ADU means $1,000. A request for 20%, 30%, or a "materials reservation fee" up front is a red flag, not standard practice.
4. What's my realistic timeline? The statutory 60-day plan check applies only to complete, compliant applications. In practice, Los Angeles ADU permitting runs about 3–6 months, and design-to-move-in lands around 8–14 months. Be skeptical of anyone promising a fixed fast-track.
5. Who is my single point of contact, and how are change orders priced? The turnkey pitch only works if one accountable person answers your calls — and change-order markup is where fixed prices quietly stop being fixed.
6. What does "financing coordination" actually include? Are they connecting you with lenders, or just handing you a brochure? Note that the $40,000 CalHFA ADU grant is currently paused and out of funds, so any pitch leaning on it deserves scrutiny.
7. Can I see recent completed projects nearby? Photos are nice. Addresses and homeowner references are evidence.

The guardrails California gives you

Whoever you hire, state law is on your side in ways worth knowing cold. The $1,000 deposit cap protects your money before ground breaks. The 60-day plan-check ceiling keeps a compliant application from rotting on a city desk. And your property taxes won't blow up: only the new ADU is assessed, at roughly 1% of its value per year — your existing home keeps its original Proposition 13 basis.

Combine those protections with a license you've verified and references you've called, and hiring any LA design-build firm — Gather ADU included — becomes a manageable decision instead of a leap of faith.

Bottom line: is Gather ADU the right builder for you?

Gather ADU makes a coherent offer: one company, one contact, all four ADU types, with permitting and financing help folded in — backed by an active Class B license and published pricing that's realistic for the LA market. What it can't yet show you on our directory is a homeowner review track record, so your job is to close that gap with references and a properly itemized contract.
