Why Herriman Is One of Utah's Hottest ADU Markets
Herriman is exploding. With 62,352 residents in 2024, we’ve grown by an incredible 3,994% since 2000 — from just 1,523 people to over 62,000 today. That’s not a typo. We’re Utah’s 13th largest city and growing at 2.09% annually.
Here’s what makes ADUs such a smart investment in Herriman:
Our Housing Market Is Red Hot
The median home value hit $637,133 in 2023 — a massive jump from $179,100 in 2000. That’s over 250% growth! With median household incomes at $118,172 (nearly double the $56,361 from 2000), Herriman homeowners have the resources and motivation to invest smartly.
Out of 16,969 housing units, 65.2% are detached single-family homes. That means thousands of Herriman families have the perfect setup for adding an ADU.
Outstanding Rental Income Potential
The median gross rent in Herriman is $1,870 per month — that’s $22,440 per year in potential rental income. With housing costs averaging $2,037 per month, an ADU rental can cover your mortgage while building long-term wealth.
Young, Thriving Community
With a median age of just 28 years old, Herriman is one of Utah’s youngest cities. About 30.1% of residents are children under 15, and 34.2% are adults between 25-44. This is a community of young families buying homes and needing flexible housing options.
Herriman Has Clear ADU Regulations
Herriman allows Internal ADUs (I-ADUs) within your existing home on lots 6,000+ square feet in R-1 Residential and Agricultural zones. The city implemented clear regulations following Utah state law, making it straightforward to add an ADU legally.
Popular ADU Services in Herriman
ADU Design & Architectural Plans
This is where your dream ADU starts! Professional designers and architects sit down with you to understand what you need — rental income? Space for family? Home office? They create detailed drawings showing exactly what your ADU will look like, where it’ll go on your property, and how everything will work. These plans are super important because the city needs to see them before you can build anything!
Garage Conversion ADUs
Already have a garage? Turn it into a cozy apartment! This is often the CHEAPEST way to add an ADU because the walls and roof already exist. Contractors add insulation, plumbing, electrical, a bathroom, a little kitchen, and boom — you’ve got a rental unit! It’s way faster and cheaper than building from scratch. Perfect if you don’t use your garage much or already park in your driveway.
Basement ADU Construction
Got an unfinished basement just collecting junk? Transform it into a beautiful apartment! Basement ADUs are popular because they’re tucked inside your existing house, so they don’t take up yard space. Contractors add a separate entrance (usually from outside), install a kitchen and bathroom, make it bright and cozy, and suddenly you’ve got rental income from space you weren’t even using!
Detached Backyard ADUs
This is a brand NEW little house built in your backyard! It’s completely separate from your main home, which means total privacy for whoever lives there. These look like tiny cottages or small homes and can be super cute! Yes, they cost more than conversions, but you get a completely custom space that doesn’t mess with your main house at all. Plus, Salt Lake City made changes that allow these to be up to 1,000 square feet, which is plenty of room!
ADU Permitting & City Approvals
This part sounds scary but good contractors handle it FOR you! Every city has rules about ADUs — where they can go, how big they can be, what they need to include. Contractors who know Salt Lake City’s rules will prepare all the paperwork, submit it to the city, answer their questions, and get your permits approved. Without proper permits, you can’t legally build OR rent your ADU, so this step is super important!
ADU Utilities & Plumbing/Electrical Setup
Your ADU needs water, electricity, heat, and sewage just like a regular home! Professional contractors connect your ADU to your existing utility lines (or add new ones if needed). They install all the plumbing for the bathroom and kitchen, wire up the electrical system safely, add heating and cooling, and make sure everything meets building codes. This is technical stuff that MUST be done right!
Full ADU Construction & Project Management
Want someone to handle EVERYTHING from start to finish? That’s what full ADU construction means! One contractor manages the entire project — design, permits, excavation, foundation, building, utilities, finishing touches, inspections, everything. You just tell them what you want, and they make it happen. No coordinating between different companies or figuring out who does what. One team, start to finish!

Types of ADUs You Can Build in Herriman
Internal ADU (Inside Your Main House)
This is an apartment INSIDE your existing home — usually a basement conversion or repurposing part of your main floor. Utah state law requires all cities to allow internal ADUs, so you can definitely build one! It shares some systems with your main house (like heating) but has its own kitchen, bathroom, and entrance. Often the cheapest option because you’re using existing space.
Size: No maximum limit!
Best for: Families wanting to house relatives while keeping them close
Average cost: $60,000 – $100,000 depending on what exists already
Attached ADU (Connected to Main House)
Like a new wing added onto your house, but it’s a complete separate apartment with its own entrance, kitchen, and bathroom. It shares a wall with your main home but functions independently. Think of it like a duplex — two separate homes that happen to touch each other.
Size: No maximum limit!
Best for: Homeowners wanting a separate space without taking up yard area
Average cost: $100,000 – $200,000+
Detached ADU (Standalone Building)
A completely separate little house in your backyard, and Salt Lake City now allows these to be up to 1,000 square feet — that’s room for two bedrooms! This gives maximum privacy for everyone. Your tenants or family members have their own space, and you keep your main house completely to yourself.
Size: Up to 1,000 square feet
Best for: Rental income or adult children/parents who want independence
Average cost: $150,000 – $300,000+ depending on finishes
Garage Conversion ADU
Turn your existing garage into a full apartment! The structure already exists, so contractors “just” need to add insulation, utilities, bathroom, kitchen, and finishes. Way faster and cheaper than building new. You lose garage storage, but you gain hundreds of dollars per month in rent!
Size: Whatever your garage size is (usually 400-600 sq ft)
Best for: Budget-conscious homeowners with garages they don’t need
Average cost: $60,000 – $120,000
What Does an ADU Cost in Herriman?
Here’s what you can realistically expect to pay (every project is different!):
| ADU Type | Typical Cost Range | Cost Per Square Foot |
|---|---|---|
| Basement Conversion (Internal ADU) | $60,000 – $100,000 | $80 – $150 |
| Garage Conversion | $60,000 – $120,000 | $100 – $200 |
| Attached ADU (New Construction) | $100,000 – $200,000+ | $150 – $250 |
| Detached ADU (New Construction) | $150,000 – $300,000+ | $200 – $350 |
| ADU Design & Architectural Plans | $3,000 – $10,000 | — |

| Utility Connections (New Lines) | $5,000 – $20,000 | — |
| Landscaping & Site Restoration | $3,000 – $10,000 | — |
What affects your cost:
- Type of ADU: Conversions are cheapest, new construction costs most
- Size: Bigger means more materials and labor
- Finishes: Basic = cheaper, luxury = way more expensive
- Site conditions: Difficult access or slopes increase costs
- Utility distance: Far from main house utilities = higher connection costs
- Customization: Unique designs cost more than standard plans
Money-Making Reality Check:
Building an ADU costs a lot upfront, but rental income can help offset your mortgage or even pay it off faster! Many Salt Lake City ADUs rent for $1,200-$1,800+ per month. That’s $14,400-$21,600 per YEAR coming in!
Why ADUs Are Exploding in Salt Lake City
The Housing Situation is CRAZY
Utah has been one of the fastest-growing states in America! More people moving here means we need WAY more housing. Regular apartments and houses are super expensive and often sold out. ADUs help by adding housing WITHOUT building giant apartment buildings that change neighborhood character.
The City Made It WAY Easier
In 2023, Salt Lake City adopted new ADU guidelines that made the process quicker and easier, plus they lowered fees by about $2,000. Before these changes, only a handful of people were building ADUs. After? Permits more than doubled! The city even created an ADU Handbook and pre-approved standard plans to help homeowners.
It’s a Smart Financial Move
Think about it: you already own the land. You’re already paying property taxes. Why not make that property work HARDER for you? Rent from an ADU can:
- Pay a big chunk of your mortgage
- Fund your kid’s college
- Build your retirement nest egg
- Give you financial breathing room
Rental demand in Salt Lake County keeps growing year after year, so you’ll likely never struggle to find tenants.
Family Needs Are Changing
More families are choosing multigenerational living — having grandparents or adult kids living nearby but not right on top of each other. ADUs are PERFECT for this! Your loved ones get privacy and independence, but you’re close enough to help with kids, cook dinner together, or check on aging parents. It’s the best of both worlds!
Salt Lake City ADU Rules You Should Know
You Don’t Need to Own Multiple Properties
Great news! You can build an ADU on a property with a single-family home — you don’t need to own commercial property or multiple lots. If you own a regular house in Salt Lake City, you can probably add an ADU!
Owner Occupancy Requirements
Most cities in Utah require that the property owner lives on-site year-round if there’s an ADU. This means YOU have to live either in the main house OR in the ADU — you can’t just own it and rent out both units while living somewhere else. This rule keeps neighborhoods stable.
Size and Lot Requirements
For detached ADUs, some cities require lots of at least 8,000 square feet. Internal and attached ADUs usually don’t have lot size minimums. Check with your contractor — they’ll know if your lot qualifies!
Parking Rules
Most cities require at least one parking space for your ADU. Good news: your driveway or street parking often counts! Contractors handle this during the design phase.
No Short-Term Rentals
You usually can’t use your ADU as an Airbnb or short-term rental — it must be rented for 30+ days. The city wants stable, long-term housing, not hotels in residential neighborhoods. Long-term rentals work great anyway — steady income, less turnover hassle!
Design Must Fit the Neighborhood
Your ADU needs to look like it belongs! It should have similar materials, colors, and style as your main house and surrounding neighborhood. Cities can require that internal ADUs not change the outside appearance of your home.
How Much Money Can You Make From an ADU?
Let’s talk real numbers! Here’s what ADUs typically rent for in Salt Lake City:
Studio/1-Bedroom ADU: $1,000 – $1,500/month
2-Bedroom ADU: $1,400 – $1,800/month
Luxury/High-End ADU: $1,800 – $2,500/month
Example: Garage Conversion ROI
Let’s say you spend $80,000 converting your garage:
- Monthly rent: $1,300
- Yearly income: $15,600
- Payback period: About 5-6 years
- After that: Pure profit (minus maintenance)!
Plus, your property value increases significantly when you add an ADU, making it worth more if you ever sell.
Example: Detached ADU ROI
Let’s say you spend $200,000 building a detached ADU:
- Monthly rent: $1,600
- Yearly income: $19,200
- Payback period: About 10-11 years
- Long-term: Steady income stream for decades!
Tax Benefits: You might be able to deduct some expenses related to your rental ADU. Talk to a tax professional to maximize your benefits!

Frequently Asked Questions About ADU in Herriman
Below are some of the most common questions Our Network get from families about ADU. If you have any other questions contact us!
How long does it take to build an ADU?
Garage/basement conversions: 2-4 months. Detached new construction: 4-8 months. Timeline depends on permits, weather, and project complexity.
Do I need special permits?
Yes! Every ADU needs city permits and inspections. Good contractors handle all of this for you. Never skip permits — you can’t legally rent an unpermitted ADU.
Can I use my ADU for Airbnb?
Usually no. Salt Lake City generally requires ADUs to be rented for 30+ days (long-term rentals). Short-term vacation rentals typically aren’t allowed in ADUs.
What if my lot is small?
Internal and attached ADUs usually have no lot size minimum. Detached ADUs might require larger lots (often 8,000+ sq ft). Your contractor will know if your lot qualifies.
How much rent can I charge?
Studio/1-bedroom ADUs: $1,000-$1,500/month. 2-bedroom ADUs: $1,400-$1,800/month. Actual rent depends on your ADU’s location, condition, and amenities.
Will an ADU increase my property taxes?
Yes, because it adds value to your property. But the rental income usually covers the tax increase many times over!
What about utilities?
Your ADU will increase utility costs (water, electricity, gas). Many landlords include utilities in rent or install separate meters so tenants pay their own. Discuss options with your contractor.
