FAQ
ADU feasibility FAQ
How much does ADU Feasibility Consultation cost in Aurora?
$350.
How do I book?
Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.
Can I build an ADU on my lot?
It depends on lot size, setbacks, HOA rules, and Aurora’s code. Autotelic helps assess feasibility—we do not invent zoning envelopes or guarantee permit outcomes.
Is the online sizing tool a permit determination?
No. Lot-aware sizing on /adu/ is illustrative only and is not a permit determination. A clear estimate and local review come next.
What happens after I start an estimate?
You move from feasibility into a clear estimate with the same design-build team, then permit coordination and build with a licensed Aurora crew when you proceed.
What will an ADU cost?
The lot lookup is free. Our ADU cost page shows planning ranges for a detached backyard cottage; your lot, utility connections and finishes affect the price. Start an estimate for your project, or call (720) 287-7958 to talk it through. A fixed-price build proposal comes after feasibility.
Who builds the ADU?
Autotelic’s local design-build team takes your project from the first concept through an estimate, permits and construction. You have one team to talk to along the way.
How much does an ADU cost in Aurora?
We don't put a single number here on purpose — the honest answer depends on your lot, the utility runs and the finish level. Our Instant Estimate reads the same published tier ranges we quote from and narrows them to your project in about two minutes: https://autotelic.build/estimate?trade=adu-backyard-cottage. It is an estimate, not a quote; after feasibility the build is quoted as a fixed-price proposal, so you know the number before work starts.
Garage conversion or detached backyard cottage?
Each has different zoning, cost, and site implications. We design all three and recommend based on your lot, budget, and how you plan to use the unit.
Should I build for a rental or for family?
The code limits on this page apply to the building no matter who lives in it — what changes is the layout and the specification. Our Premium tier is written as a rental-ready one-bedroom (complete kitchen, laundry, private entrance); family and multigenerational use more often points to a Studio ADU or a lofted Signature plan. Run the lot check for the size you are allowed, then the estimate for the tier price.
What are the drawbacks — permits, timeline, neighbors?
Two municipal reviews run in order: a zoning review confirming the unit fits your district’s standards, then a building permit review of the construction documents, with inspections during the build and a certificate of occupancy at the end. Aurora building permits are issued by the Building Division's Permit Center, which also handles public improvement, sign, and lawn and irrigation permits. Contractor licensing is a City of Aurora requirement, and applications go through the Aurora4Biz.org online portal. We manage zoning review, the permit application and every inspection through certificate of occupancy.
