Detached ADU Construction
Feasibility First.
We don't start by selling you a build. We start by honestly evaluating whether your property qualifies — zoning, setbacks, utilities, HOA, and financing. If it checks out, we're with you all the way to occupancy.

Utah Senate Bill 284, signed into law on March 18, 2026, requires qualifying municipalities to permit detached ADUs (DADUs) on lots of 11,000 square feet or larger that already have a single-family home in a single-family dwelling zone.
Before SB 284, Lehi's ADU threshold was approximately 14,500–15,000 sq ft. The new statewide floor of 11,000 sq ft makes thousands of previously ineligible homeowners newly eligible to add a detached ADU.
This is a limited-time opportunity — cities must comply, but they can still apply specific setback, parking, and design requirements. Acting now means working with current rules before cities layer in additional restrictions.

Our Complete Process
Every step exists for a reason. We don't skip the feasibility work — it's what protects you from costly surprises.
Lead & Property Screen
FreeYou reach out. We pull your parcel data, check lot size, zoning classification, and existing structures. Free, 24–48 hours. We tell you immediately if it looks viable.
Site Consultation
On-siteWe visit the property with you. We walk the lot, identify setback constraints, note existing structures, locate utility access points, and assess site access for construction.
Full Feasibility Report
Written ReportWritten report covering: zoning compliance, setbacks from all property lines, HOA/CC&R review, utility availability, parking analysis, financing capacity, and potential use cases.
Design Package — $5,000
$5,000 Flat FeeIf feasibility checks out, we produce permit-ready architectural plans for your specific lot and DADU design. Built to current IBC/IRC standards and local city requirements.
City Planning & Building Approval
We Handle ItWe submit plans to city planning and building departments. We handle the back-and-forth with plan checkers, respond to corrections, and get your permit issued.

Common Questions
Does SB 284 mean my city has to let me build an ADU?
SB 284 requires qualifying municipalities to permit DADUs on lots ≥11,000 sq ft with single-family homes in SFD zones — but cities can still apply setbacks, parking requirements, design standards, and other conditions. It opens the door; it doesn't eliminate all local rules.
Can I rent it out on Airbnb?
Possibly not. Many Utah cities prohibit short-term rentals (less than 30 or 90 days) in residential zones. SB 284 does not override local short-term rental bans. Long-term rentals (12-month leases) are generally allowed. We'll check your specific city's rules during feasibility.
What's the $5,000 design package?
It's a flat-fee permit-ready architectural plan set — drawings that meet your city's requirements for building permit submission. This includes site plan, floor plans, elevations, and structural details. It's not a napkin sketch; it's what goes to the permit office.
What if my HOA says no?
HOA and CC&R restrictions can override SB 284 in some cases. We review your HOA documents as part of feasibility before recommending you invest further. If HOA approval is possible, we'll tell you what the path looks like.
How much does a DADU cost to build?
Utah DADU construction costs vary significantly based on size, finish level, site conditions, and utility connections. We don't give ballpark numbers before feasibility because they're almost always wrong. After a proper site consult and feasibility, we can give you a real estimate.
How long does the whole process take?
From feasibility through occupancy, typically 12–18 months depending on city review timelines, design complexity, and construction schedule.
