Yes. Finishing a basement in Logan requires a building permit, and so does finishing one in every other town in Cache Valley. The part worth understanding is who issues it, what they want from you, and what the process actually looks like once you file, because that is where most of the confusion lives.
Who Issues Your Permit Depends on Which Town You Are In
Cache Valley is split, and homeowners are often surprised by which side they fall on.
Logan, North Logan, Nibley and Hyde Park each run their own building department. You file with the city and the city inspects the work.
Providence, Smithfield and Hyrum work differently. You get a zoning clearance from the city first, then Cache County issues the building permit and handles the inspections. Same goes for the unincorporated county and for most of the smaller towns around the valley.
If your project is in Logan, that is the Building Department at 290 North 100 West, reachable at 435-716-9030. Logan publishes a review window of up to two weeks. If it goes through the county, that is Cache County Building at 179 North Main Street, Suite 305, on 435-755-1650, with a published review time of three to ten working days for average structures.
Worth calling before you plan around either number. Both are published figures rather than guarantees, and a busy season moves them.
What You Actually Hand In
The submittal package for a basement finish is more than a sketch, and less than a full architectural set.
You need 2D plans of the space, plus a separate plan covering electrical on its own. You need a written scope, which is a plain description of everything going into the basement. And you need license information for the general contractor and for every trade on the job: electrical, plumbing, HVAC.
If any engineering was involved on the project, they will want that engineer’s license number along with their address, phone and business details.
That last piece catches people managing the project themselves. The city wants to know who is doing the work and whether those people are licensed to do it. Assembling that paperwork out of four different subcontractors is its own small job, and it has to be done before anything gets filed.
What It Costs
Permit fees here are valuation-based, meaning they scale with the value of the work rather than sitting at a flat rate.
Cache County adopted its current schedule in November 2024 and names basement finishing as its own line item at a $300 base fee plus $50 for plan review. The county calculates valuation by square footage, with basement space figured at $80 per square foot for that purpose.
Logan runs its own valuation-based schedule. Residential plan review there is 0.1 percent of construction valuation with a $15 minimum.
Against a basement finish that runs $60,000 to $180,000 or more depending on scope, the permit is a rounding error. Sit with that for a second. The fee is almost never the real reason anybody skips a permit. What people are actually avoiding is the time, the paperwork and the inspections, and those are the parts that protect them.
The Thing That Surprises People on Newer Homes
If your house is relatively new, check with the building department before you assume anything about the fee.
We finished a basement in a North Logan home that was about four years old, and the permit fee came in far lower than expected. The basement had already been accounted for in the original permit when the house was built, so a good portion of it was already paid.
That will not be true of every new build and it is not something to count on. Worth a five minute phone call anyway, because it occasionally saves a few hundred dollars.
The Inspection Sequence
Once the permit is issued, a basement finish runs through three inspections, and this sequence holds on nearly every project we run.
The first is the four way inspection. One visit covering framing, rough electrical, rough plumbing and rough HVAC, all at once, while the walls are still open. This is the one that matters most, because everything checked here disappears behind drywall the moment it passes.
The second comes after installation, once the systems are in and the finishes are going on.
The third is the final inspection at the end of the project. That is what closes the permit out, and until it happens the permit is still open against your address.
Our post on what to expect during a final inspection covers that last visit in detail.
Egress Is the Part Cities Do Not Negotiate On
Under the International Residential Code, basements, habitable attics and every sleeping room require at least one operable emergency escape and rescue opening. Where a basement contains bedrooms, each bedroom needs its own.
This is the requirement that generates the most friction on basement plans, and it is the one inspectors are least flexible about. Fire is the reason. A basement is the hardest part of a house to get out of, and a bedroom down there with no exit besides the stairs is a genuine hazard rather than a paperwork issue.
Confirm the current adopted code edition with your building department, since editions change and local amendments exist.
The Nibley Groundwater Rule
If your project is in Nibley, there is a requirement that can change the floor height of an entire basement, and almost nobody mentions it.
Nibley publishes elevation rules tied to groundwater. Where groundwater sits within 48 inches of the surface, finished floors must be at least six inches above the street curb. Going below that requires a professional engineer’s water table report, a floor at least a foot above that elevation, and a groundwater discharge system approved by the City Engineer.
That is not a detail you want to discover after framing. If you are in Nibley and your basement sits low, ask about it during planning.
Who Should Pull It
We pull the permit on every job we run, and I would argue that is one of the clearer arguments for hiring a general contractor on a basement.
Somebody doing this every week knows what the city wants before they ask for it. The package goes out within a couple of days of a signed contract because it is already assembled. And when something comes back, whether that is a plan review comment or a failed inspection or a question nobody anticipated, your contractor handles it.
None of that means the city is difficult to deal with. Cache Valley building departments are reasonable and they answer the phone. But your general contractor is your advocate between you and the city, and having somebody in that seat who has done it fifty times is worth something on a project this size.
If you are planning a basement in Logan, North Logan, Providence, Smithfield, Hyde Park, Nibley or Hyrum and want to know what your jurisdiction will ask for, that is a quick conversation. You can request an estimate, read more about basement finishing in Cache Valley, or look through finished basements we have built.
