我们做什么
亚利桑那在2024年重写了ADU规则。我们也重写了我们的ADU包。独立、附建或车库改造 — 我们处理退线、高度包络、独立水电表,以及让大多数首轮ADU申报失败的母地块限制。
- 按区划遵守 2024 年州级 ADU 规则 (R1-6 → R1-18)
- 制图前进行退线与高度包络研究
- 独立水电表协调
- 按城市 ADU 送审清单编制的申报图集
您得到什么
- 申报图集,含 ADU 与主屋更新图页;城市要求的工程部分由独立注册专业人士完成并盖章
- 含管线走向、退线尺寸的总平面图
- 新增住宅的能源合规
- 城市要求时提供的业主居住声明(例如凤凰城用作短租的 ADU)
- 业主融资用的成本估算表
- 审图回复包含两轮
当地细节
凤凰城每月公布住宅审图目标时间 — 我们会在您确定开工日期前查看最新报告。我们先按 2024 年州 ADU 法(退线、停车、面积)与市级 ADU 标准(高度、退线)预审,再做区划。Sun City(Maricopa 县非建制区)、Glendale、Chandler、Surprise — 各有规定,我们的项目录入表会捕捉这些。
报价
固定费用。ADU 改建 $6,000 起;600 平方英尺以内的新建独立 ADU $9,400 起。Proven Sets 在 Phoenix、Mesa 与 Scottsdale $3,000 起。城市要求的工程与盖章在报价中单独列项。
问答
常见问题
Are you familiar with my city's ADU program?
Yes — before we draw, we check your city’s ADU ordinance and whether a "standard plan" program applies. For cities new to us, we research the specific ordinance during the first week and flag any oddities upfront.
Can you do the ADU plus a related main-house remodel?
Yes — common pattern. We package both into a single set so the AHJ can review them together and you don't pay for two permit cycles when one will do.
What about utility easements and setback variances?
We map setbacks and easements during schematic phase. If a variance is needed, we either redesign to avoid it (usually cheaper) or document the variance package — the variance hearing itself goes through a local land-use attorney.
Do you stamp drawings?
No — we are a drafting studio, not a registered architecture or engineering firm, and we never apply a seal. Where a project needs an engineer’s seal, an independent engineer registered in your state is responsible for that part of the work: they prepare it, or directly supervise its preparation, and seal it. Engineering and seals, where your city requires them, are separate lines on your quote, so there are no surprises. If a project needs a registered architect, we refer you to one instead of taking it.
Do you submit permits on my behalf?
Yes — for an itemized fee, we file the permit package directly with the AHJ, handle correction cycles, and shepherd the set through to issuance. Or you can take the finished set and submit it yourself. Your call; either way, the drawing scope is the same.
What is your revision policy?
Every fixed-fee quote includes two rounds of revisions before construction documents are finalized. On a standard quote, our answers to the city’s comments on items in our scope are included, and if the city flags an error in our drawings, we fix it free. Substantive scope changes after CD freeze are quoted separately, as a fixed price, before the work starts.
Can you work with my existing GC, engineer, or interior designer?
Yes. We routinely coordinate with general contractors, structural / MEP engineers, kitchen designers, and interior designers your team has already retained. We work in their CAD format, attend their coordination meetings, and produce drawings that bid cleanly against their scope.
How fast can you turn around a set?
A Permit-Ready set typically takes 4–6 weeks from a complete brief. Your delivery date is in writing on the quote.
What languages do you work in?
This website is in English, Spanish, and Chinese, and your proposal, agreement, estimates, and invoices can also be shown in Chinese (the English version governs). We can issue drawing sets bilingually if your trade contractors prefer Spanish — useful in Phoenix, Las Vegas, and Texas markets.
What insurance do you carry, and who is responsible if a drawing error causes a problem during construction?
We carry general liability insurance, and we re-cut any drawing issue we caused at no charge. Because we are a drafting studio, any sheet that needs an engineer’s seal is prepared or directly supervised, and sealed, by an independent registered engineer who carries their own professional (errors-and-omissions) liability for that work. Ask us for our certificate of insurance before you sign.
Do I own the drawings, and can I get the editable CAD files?
You receive the permit-ready set you paid for, and your contract spells out your rights to the files. If you need the native, editable CAD (DWG) — to hand to a builder, a sub, or another firm — tell us during intake so we confirm the deliverable format up front rather than at handoff.
What do you need from me to get started, and how much is the deposit?
To quote, we need your project basics: the location or parcel, your scope, and any survey, existing plans, or even a rough sketch. Engagements start with a deposit at contract signing — paid by card, ACH, or check through the client portal — with the balance tied to project milestones. You do not need an architect's drawings to begin; we work from a napkin sketch or pick up an architect's earlier design.
Can you tell me what my project will cost to build, not just to draw?
We don't quote construction costs — that's your general contractor's bid, and it depends on finishes, site conditions, and the current local labor and material market. We design to a clear, complete scope so your GC can price it tightly with fewer surprises, and we can connect you with GC partners for a build estimate.
