Building ADUs in North Salt Lake
North Salt Lake occupies the southern tip of Davis County — 8.6 square miles with roughly 21,900 residents, bordered by Woods Cross to the north, Bountiful to the north-east and Salt Lake City to the south. It is the closest Davis County city to downtown Salt Lake, and the first one most people pass through heading north.
What defines building here is elevation change. Much of the city climbs away from the valley floor, and a great many properties sit on genuine slope rather than the gentle grade you get further north. On a sloped lot the foundation stops being a formality: stepped footings, retaining and a drainage plan that routes water around the new structure all become part of the design rather than details resolved on site.
That is not a reason to avoid a detached unit — plenty get built on these lots. It does mean the siting decision matters more than usual. Where the unit sits on a slope determines the foundation cost, whether the entrance can be level, and how much excavation is involved before anything gets framed.
The other recurring constraint is access. Getting equipment and material to the back of an elevated lot, past a house, is frequently the first thing we assess — and occasionally the thing that points a project toward a conversion instead.
What Shapes an ADU Project in North Salt Lake
Slope Is the First Question
Grade affects foundation type, retaining, drainage and where a level entrance can sit. On North Salt Lake properties this gets assessed before anything else, because it shapes both the design and the budget.
Access Before Aesthetics
Reaching a rear building site on an elevated lot past an existing house is a real constraint. We check the route equipment and material would take before discussing floor plans.
Closest Davis City to Salt Lake
Bordering Salt Lake City to the south, North Salt Lake suits homeowners who want a separate unit for family or long-term rental within easy reach of the valley.

North Salt Lake Property Conditions to Plan For
On a North Salt Lake property these are the items that decide the project:
- Degree and direction of slope — gentle fall is manageable; a steep drop changes the foundation approach entirely
- Drainage and runoff paths — water has to be routed around a new structure on a hillside, not simply allowed to find its own way
- Retaining requirements — often the difference between a straightforward build and an expensive one
- Rear access route — width, gradient and surface of the path equipment would take to the build site
- Whether a level entrance is achievable — critical if the unit is for a parent or anyone with mobility limits
- Utility runs across grade — trenching uphill costs more than trenching across flat ground
Where slope or access rules out a backyard build, the usual alternatives are a garage conversion or a basement conversion, both of which sidestep the excavation entirely. Where the lot allows it, a detached ADU still gives the most separation. Either route starts with design work grounded in the actual grade.

ADU Questions From North Salt Lake Homeowners
What comes up most often when we walk properties in North Salt Lake.
Are ADUs allowed in North Salt Lake?
Utah state law makes internal ADUs — units created inside an existing home — a permitted use in most residential zones statewide. Detached units are governed by North Salt Lake City ordinance instead, and cities can apply parking, owner-occupancy and rental licensing requirements. Because those rules change, confirm the current position with North Salt Lake City during planning. We prepare what the process requires and coordinate it with you.
Does a steep lot make an ADU unaffordable?
Not usually, but it does add cost that a flat lot would not carry — deeper excavation, stepped or retained foundations and more drainage work. The honest answer is that we cannot tell you how much until we have seen the grade. What we can do at the walkthrough is tell you whether the slope is a modest premium or a genuine obstacle.
Can equipment reach my backyard?
That is one of the first things we check in North Salt Lake, because a narrow or steeply rising side yard can rule out a rear foundation pour. Where access is genuinely blocked there are sometimes workarounds, and sometimes the right answer is to convert existing space instead. We would rather establish that at the start than halfway through.
Can I get a single-level unit on a sloped property?
Often yes, and it is worth asking for explicitly if the unit is for aging parents. On a slope the design question becomes where the unit sits so that its entrance can be reached without steps. That usually favours a particular position on the lot, which is exactly the kind of decision siting is meant to settle.
