Why an ADU in Erda, and why now

The land you already own in Erda is the last unlocked asset.

Buying a second home near Erda is slow and expensive, and often impossible for the people you love. An accessory dwelling unit keeps family close, creates legal rental income, and raises the value of the property you already own — without leaving Erda Acres, Bates Canyon, Droubay Road or anywhere else in Erda.

Multi-acre parcels meet every setback and separation standard comfortably, and there is room to place the unit for privacy.

Envision Utah estimates the state will need roughly 840,000 new homes by 2055, with current production falling about 235,000 short. ADUs are one of the few ways a Erda homeowner can add housing without waiting on a new subdivision.

Three reasons Erda homeowners build

For grandma. For the kids. For cash flow.

An ADU — or granny flat — is not a one-use structure. Many families start with a parent or adult child, then rent the unit later — or the reverse. We design for both life stages.

Aging parents, with dignity

Keep mom or dad on the property instead of searching for a room somewhere across the valley. A lockable suite with a kitchen, bath, and separate entrance preserves independence and puts help 30 seconds away — right here in Erda.

Adult kids who can’t break in

Starter homes near Erda are brutally competitive. A well-built granny flat gives a newly married couple, a student, or a returning adult child a real home while they save — without living on top of each other.

A rental on land you already paid for

Multigenerational households and long-term tenants working the Tooele and Salt Lake corridors. Long-term rent can offset the mortgage and raise resale value. Short-term rental is restricted in most cities, so we design for legal 30-day-plus tenancy.

Aging in place, together

A granny flat lets your family age gracefully under one roof

More Utah families are choosing a private in-law suite or backyard cottage so parents can stay close without giving up independence. A bedroom, full bath, kitchenette, and level entry mean help is nearby — and dignity stays intact.

  • Kitchenette, laundry, and full bath
  • Level thresholds and safe circulation
  • Close to family, not a facility

Let's design the perfect ADU for your life and property

These are concept plans — not your lot’s final drawings. On the site assessment we match setbacks, parking, height, and whether an internal unit or a detached cottage is the smarter first move.

Internal vs. detached in Erda

Two legal paths. We tell you which one your lot can actually win.

Internal ADU. Built inside the existing house — most often a basement apartment. Fastest path in many cities because Utah’s HB 82 already treats qualifying internal units as a permitted use. Needs egress, a kitchen, a bath, parking, and in many places owner occupancy of one of the two dwellings. If your Erda basement is framed and unfinished, start with our Erda basement finishing page.

Detached ADU. A backyard cottage, garage conversion, or new accessory structure. Highest rent and the cleanest privacy. Tooele County Planning reviews Erda accessory dwelling applications, septic and well capacity, and access.

This is the part homeowners underestimate. Setbacks, lot coverage, parking replacement, water-provider letters, owner occupancy, and short-term rental bans are where DIY plans die. We run that gauntlet before you spend on a foundation in Erda.

How we work

We handle the tricky part: Erda city review.

Todd McBride has built in Utah for more than 20 years. Outlook Builders has been a custom builder since 2011. ADUs fail when design ignores parking, water, fire, and owner occupancy. We start there.

01

Site assessment

Lot size, zone, setbacks, parking, utilities, and whether internal or detached is even legal on your Erda parcel.

02

Design that matches the house

Floor plan, elevations, and finishes that look like Outlook work — not a backyard afterthought.

03

Permits & city comments

Building permit, water-provider letter, address marker, parking proof, and the back-and-forth with Erda planning staff.

04

Build & inspections

Weekly communication, trade coordination, and a unit you can house family in or rent legally. Financing is lined up before construction — not after the first invoice.

Money should not stall the ADU

Don’t worry about financing. We’ll take care of that with you.

Outlook Builders has dedicated financing for this exact work. You do not need to shop five lenders or pause the design while you figure out cash. We time the money to the project — after we know what your Erda lot can take, before we break ground.

ADU questions Erda homeowners ask

Straight answers before you call

Can I legally build an ADU in Erda, Utah?

In most residential zones, yes. Utah’s HB 82 made qualifying internal ADUs — usually a basement apartment — a permitted use in much of the state, and SB 284 expands detached ADUs as a permitted use on qualifying lots (generally 11,000 sq ft and up) in specified municipalities beginning October 1, 2026. Tooele County Planning reviews Erda accessory dwelling applications, septic and well capacity, and access. We confirm what your Erda parcel allows before any design work starts.

Internal or detached ADU — which one works better in Erda?

Multi-acre parcels meet every setback and separation standard comfortably, and there is room to place the unit for privacy. An internal ADU is faster and cheaper because the shell already exists. A detached cottage costs more but rents higher and gives both households real privacy. On the free site assessment we walk your lot in Erda and tell you which one is actually approvable.

How much rent can an ADU in Erda bring in?

Along the Wasatch Front, internal ADUs commonly rent from about $1,100 to $1,500 a month, and well-finished detached cottages often reach $1,500 to $2,200 or more. Multigenerational households and long-term tenants working the Tooele and Salt Lake corridors. Exact rent depends on size, finishes, parking, and local rules — these are market illustrations, not a guarantee.

Do I need extra parking for an ADU in Erda?

Usually yes. Most Utah cities require the ADU’s parking stall in addition to whatever the main home already needs, and losing a garage to a conversion can trigger a replacement stall. Erda reviews this at permit, so we design parking into the site plan rather than discovering it during review.

Can I short-term rent an ADU in Erda?

Generally no. State law frames internal ADUs around 30-day-plus tenancy, and many cities — including resort communities — restrict nightly rental of accessory units outright. We design Erda ADUs for family use or long-term tenancy so the unit stays legal.

How long does an ADU project take in Erda?

Design, city review, and construction each have their own clock, and Tooele County inspection timelines vary with the season. You get a schedule at the scope stage and weekly updates once we start.

Do I have to figure out the financing myself?

No. Outlook Builders has dedicated financing, so you are not shopping lenders alone. We introduce it at the right point — after the plan is real, before construction — and walk it with you. Ask for it on the free site assessment.
