Key Takeaways
- The fastest path to a quote is submitting a free ADU quote request online, which triggers a scheduling call within one to two business days.
- A site assessment — a visit to review lot size, setbacks, and utility access — comes before any firm number is provided.
- theadupro.com holds an active CSLB (California Contractors State License Board) license.
- Quotes typically cover design, structural engineering, permitting, and construction as a single package rather than separate bids.
- Financing discussions, including HELOCs (home equity lines of credit) and ADU-specific loan programs, can happen alongside — not after — the quoting process.
What Is an ADU Quote From theadupro.com?
An ADU quote from theadupro.com is a cost estimate for designing, permitting, and building an accessory dwelling unit — a secondary, independently livable housing unit on a residential lot. Unlike a single trade bid, it bundles architectural design, structural engineering, permit coordination, and construction into one proposal, because the company operates as a design-build contractor rather than a separate architect-then-contractor arrangement.
In practice, this means a homeowner does not need to collect separate estimates from a designer, an engineer, and a builder. Instead, theadupro.com assembles those costs into one proposal after evaluating the specific lot. As a result, the quote reflects the realistic scope of a detached ADU, attached addition, garage conversion, or JADU (junior accessory dwelling unit, a smaller unit typically created within an existing home’s footprint), rather than a generic per-square-foot average pulled from an online calculator.
How to Get a Quote From theadupro.com for an ADU Build
Getting a quote from theadupro.com for an ADU build follows a fairly consistent sequence, regardless of whether the project is a detached backyard unit in Corona or a garage conversion in Temecula. Below is the typical process, step by step.
- Submit an online request or call directly. Visit the free ADU quote request page and share your address, property goals, and preferred ADU type so the team can confirm basic eligibility first.
- Schedule a site assessment. A representative visits or reviews your property remotely to check lot size, existing structures, setbacks, and utility hookups before any pricing is finalized.
- Discuss ADU type and budget range. You and the team compare detached ADUs, attached additions, second-story additions, and garage conversions against your rental income goals, family needs, and available lot space.
- Receive a custom floor plan concept. theadupro.com’s in-house design team sketches a site-specific layout, typically ranging from 500 to 1,200 square feet, tailored to your lot rather than a generic template.
- Review the written cost proposal. The proposal outlines design, structural engineering, permitting, and construction costs together, giving you one accountable number instead of three separate bids to reconcile.
- Explore financing and move toward contract. If needed, the team can connect you with third-party lending partners for construction loans or HELOCs before you sign and permitting begins.
What Information You Need Before Requesting an ADU Price Estimate
Before requesting an ADU price estimate, it helps to gather a few basic facts about your property. Specifically, your property address, approximate lot size, and whether you have an existing garage or detached structure all shape the earliest feasibility conversation. In addition, knowing your primary goal — rental income, multigenerational housing, or added property value — helps the team recommend the right ADU type sooner.
You do not need architectural drawings or a finalized budget to start. However, having a rough sense of your financing approach, whether that’s savings, a HELOC, or a construction loan, allows the design team to frame options that fit realistically within your range rather than presenting plans you’d later need to scale back.
How Long Does It Take to Receive Your ADU Build Quote?
Most homeowners receive a preliminary estimate within a few days of the first call, while a detailed, written proposal usually follows the site assessment within one to two weeks. Timelines can vary, though, depending on city-specific zoning research and how quickly the homeowner confirms the preferred ADU type.
What Happens After You Submit Your Request for an ADU Quote
Once you submit your request for an ADU quote, a team member typically reaches out within one to two business days to confirm property details and schedule the site visit. Meanwhile, you can start thinking through secondary questions: which rooms or yard areas you’re willing to give up, whether an HOA (homeowners association) exists on your property, and how soon you’d like construction to begin.
During the site visit, the assessor checks setback requirements, utility proximity, and soil or slope conditions that affect foundation costs. Afterward, the design team builds a custom floor plan concept, and the estimating team prices out structural engineering, Title 24 energy compliance (California’s building energy standard), and construction labor together. Consequently, by the time you see numbers, they reflect your actual lot rather than a national average.
“The biggest gap I see isn’t in the building — it’s between what’s promised in a sales pitch and what’s actually delivered on the job site and in the permit office. A real quote should reflect both.” — Founder, theadupro.com
How Much Does an ADU Cost in Southern California?
ADU costs in Southern California vary widely based on size, finish level, and lot conditions, which is precisely why a site-specific quote matters more than a flat per-square-foot number. Generally, detached ADUs cost more than garage conversions because they require new foundations and utility extensions, while JADUs tend to be the most affordable since they often reuse existing walls and systems.
For a detailed cost breakdown specific to design-build pricing, see this guide on how much it costs to build an ADU with theadupro.com in Southern California. According to the California Department of Housing and Community Development, statewide ADU permitting has grown substantially since 2017 reforms streamlined approval rules, which has in turn increased contractor demand and made early, accurate quotes more valuable than ever.
If your household includes aging parents or adult children, it’s also worth reviewing how floor plans can be adapted for shared living. This guide on whether theadupro.com can customize an ADU for multigenerational living explains common layout adjustments homeowners request during the quoting stage.

Frequently Asked Questions About Getting an ADU Quote
What is an ADU, and why does it need a specialized quote?
An ADU, or accessory dwelling unit, is a secondary, independently livable housing unit built on a lot that already has a primary home. It needs a specialized quote because design, structural engineering, permitting, and Title 24 energy compliance all affect cost differently than a standard home remodel.
How to get a quote from theadupro.com for an ADU build?
How to get a quote from theadupro.com for an ADU build comes down to submitting an online request or calling directly, then scheduling a site assessment so the team can price your specific lot. A written proposal typically follows within one to two weeks of that visit.
Is the initial site assessment free?
Yes, the initial site assessment is part of the free quote request process and does not obligate you to sign a contract. It exists to confirm feasibility and produce an accurate estimate rather than a generic placeholder number.
What information should I prepare before requesting a quote?
You should have your property address, rough lot size, and primary goal — such as rental income or multigenerational housing — ready. Beyond that, the team gathers remaining details during the call and site visit.
How does a design-build quote differ from a general contractor’s bid?
A design-build quote bundles architectural design, engineering, permitting, and construction into one proposal, whereas a general contractor’s bid often covers construction only. As a result, design-build quotes reduce the risk of mismatched budgets between the design phase and the build phase.
What factors most affect ADU cost in Southern California?
Lot conditions, ADU size, finish level, and utility connection distance are the biggest cost drivers. In particular, detached ADUs with new foundations typically cost more than garage conversions that reuse existing structure.
Does theadupro.com serve my city?
theadupro.com primarily builds in Orange County, Los Angeles County, Riverside County, and San Bernardino County, with site assessment reach extending into San Bernardino County. It does not currently serve San Diego County or Northern California.
Can I get a quote before securing financing?
Yes, you can request and receive a quote before financing is finalized. In fact, having a proposal in hand often makes conversations with lenders about HELOCs or construction loans more productive, since you’ll have real numbers to reference.
What common mistakes should homeowners avoid when requesting an ADU quote?
One common mistake is comparing a design-build quote directly against a construction-only bid without accounting for design and permitting costs already included. Another is skipping the site assessment step and relying solely on online cost calculators, which rarely reflect lot-specific conditions.
What’s the difference between a detached ADU quote and a garage conversion quote?
A detached ADU quote includes new foundation work and full utility extension, while a garage conversion quote typically reuses existing walls, roofing, and some utility lines. Consequently, garage conversion quotes are often lower, though not always, depending on required structural upgrades.
How long does the full process take from quote to move-in?
Timelines vary by city, but homeowners should generally expect several months for design and permitting, followed by several more months of construction. Permit processing time, in particular, depends heavily on the specific city’s review queue.
Does requesting a quote obligate me to sign a contract?
No, requesting a quote does not obligate you to move forward. It simply gives you a documented basis for deciding whether an ADU fits your budget and goals.
What happens after I approve my ADU quote?
After approval, the team finalizes construction drawings, submits permits to your city, and schedules structural engineering review. Once permits are issued, construction scheduling begins, followed by inspections and certificate of occupancy coordination near project completion.
In short, learning how to get a quote from theadupro.com for an ADU build is less about paperwork and more about a short, guided conversation: submit a request, complete a site assessment, review a custom proposal, and decide whether to move forward. Because the quote bundles design, engineering, permitting, and construction, homeowners in Orange County, Los Angeles County, Riverside County, and San Bernardino County get one accountable number instead of several disconnected bids. For most, the clearest next step is simply starting that first conversation and letting the site-specific details shape the real cost from there. Readers can also explore general background on accessory dwelling units via the Wikipedia overview of secondary suites or verify any California contractor’s license status through the California Contractors State License Board before signing any agreement.
