Post Falls sits on the Spokane River in Kootenai County, between Coeur d'Alene and the Washington line, and it is one of the fastest-growing cities in North Idaho. That growth shows up in the work we do here: street after street of newer subdivisions where the homes went in faster than the storage did. We build custom storage sheds, garages, and backyard buildings right on your property in Post Falls — assembled on your lot rather than trucked in finished — so the building fits the yard you actually have.
A lot of Post Falls lives in a planned subdivision now, from the neighborhoods near the river and Q'emiln Park to the newer phases spreading north toward Prairie and Seltice. Those lots tend to be flat, fenced, and tight on side-yard room, and most of them sit inside an HOA with its own rules about outbuildings. Building in place is what lets a shed work in that setting — the crew fits it through the gate you have, sets it where the covenants allow, and matches it to the house instead of dropping a generic box on the pad.

Most Post Falls customers come to us with one of a few problems. The two-car garage filled up the first winter and there is nowhere to put the mower, the river toys, or the kids' bikes. The new build came with a small yard and no outbuilding at all. Or they want a finished backyard room — a quiet home office away from the house, or a she shed studio that closes the door on the noise. We build all of it on your lot. A storage shed clears the garage so the cars fit again, a detached garage or shop adds real bay space for a project or a side-by-side, and a finished studio turns a corner of the yard into usable square footage.
Subdivision access is the part we plan around first. Post Falls backyards are often reached through a single 4-foot gate or a side yard pinched between the house and the fence, and a finished shed simply cannot get back there. Building in place means the building still lands exactly where you want it — no crane, no pulling fence panels, no settling for the front corner. On lots closer to the Spokane River and the bluffs above it where the ground is not perfectly level, we plan the pad and footprint around the grade so the building sits square and drains away from the structure.
Mowers, river gear, bikes, and the seasonal totes come off the garage floor and into a dry, organized building so the cars fit through the winter.

Post Falls and Kootenai County handle accessory buildings the way most of North Idaho does: smaller utility sheds under a set square-footage threshold usually skip a building permit, while larger footprints, anything wired or plumbed, and any building you intend to occupy generally need one. Permits inside city limits run through the City of Post Falls; lots in the surrounding county go through Kootenai County. Even when no permit is required, setbacks still are — your building has to sit a minimum distance from side and rear property lines, and lots near the Spokane River or in floodplain can carry extra restrictions.
Because so much of Post Falls is in a subdivision, the HOA is usually the bigger hurdle. Neighborhoods like Prairie Falls, The Highlands, and Montrose have architectural committees and CC&Rs that often go well beyond county code — dictating siding, roof color and pitch, building size, and exactly where an outbuilding may sit. Read your covenants and get written approval before you finalize anything. Our permits and placement guide covers the county basics and setbacks, and the storage shed planning guide helps you lock in a size before you apply.

Post Falls winters are real Panhandle winters. A shed here has to carry a meaningful snow load on the roof, shrug off freeze-thaw at the foundation, and keep a door that still swings after a storm drops several inches overnight. We build to the roof pitch and anchoring the local load calls for, and we set most buildings on a compacted gravel pad that drains snowmelt and keeps the floor up off wet ground — a better fit for North Idaho than a slab that traps water against the structure.
Most Post Falls subdivision lots are flat and graded, which makes for a clean, fast pad, but the newer phases and the parcels closer to the river basalt are not always level, and some stay damp into spring. We level and drain the pad so the building stays dry and square for the long haul either way. A 10x16 or 12x16 covers most Post Falls storage and shop needs with room to grow, while a compact 8x12 tucks neatly into a tighter subdivision backyard without eating the whole lawn.
Post Falls, Kootenai County, on the Spokane River between Coeur d'Alene and the Washington line — permits run through the City of Post Falls or Kootenai County depending on where your lot sits.
Small utility sheds often skip a permit; larger footprints, occupied buildings, and anything wired or plumbed usually need one — and in most subdivisions, HOA approval is required on top of it.
Plan for a meaningful winter snow load on the roof, freeze-thaw at the foundation, and a gravel pad that drains snowmelt away from the building.
We build on-site anywhere in Post Falls — tight subdivision gates, narrow side yards, and fenced backyards are all handled in place, no crane needed.
It depends on size, use, and where your lot sits. Smaller utility sheds under the local square-footage threshold usually do not need a building permit, but larger buildings, anything you plan to occupy, and any shed with power or plumbing generally do. Permits inside city limits run through the City of Post Falls, while lots in the surrounding county go through Kootenai County. Setbacks from property lines apply either way, and lots near the Spokane River or in floodplain can carry extra rules. We help you size and place the building to fit, and our permits guide covers the basics.
In most Post Falls subdivisions, yes. Neighborhoods like Prairie Falls, The Highlands, and Montrose have architectural committees and CC&Rs that govern outbuildings — often specifying siding, roof color and pitch, maximum size, and where the building may sit. That approval is separate from any city or county permit, so plan for both. Read your covenants and submit for written approval before you finalize anything. We match the building's style, roofline, and placement to what your HOA allows so it fits the neighborhood and clears the architectural review.
Yes — that is most of what we build here. Post Falls newer subdivisions tend to have flat, fenced lots with limited side-yard room, and a finished shed often cannot fit through the gate to reach the backyard at all. Because we build on-site, a tight 4-foot gate or a narrow side yard is not a dealbreaker — the building goes together in place, exactly where you want it. For smaller lots, a compact 8x12 or 10x12 stores the mower, bikes, and seasonal gear without taking over the yard, and we place it to keep your required setbacks from the property lines.
For most Post Falls yards, a 10x16 or 12x16 hits the sweet spot — enough room for the mower, river gear, bikes, and the seasonal overflow that fills a two-car garage, with space to grow. Tighter subdivision backyards often do well with a compact 8x12 or 10x12, while homeowners on larger lots toward the county frequently step up to a detached garage or shop. We size the building to your lot, your access, and what you actually need to store.
Yes. A finished backyard room is one of the more popular requests we get in Post Falls, especially from remote workers who want a quiet office away from the house and from homeowners who want a studio or retreat. We can insulate and wire the building so it stays comfortable through a North Idaho winter and works year-round. If your lot is in an HOA, an occupied building usually needs both a permit and architectural approval, so we plan the size, windows, and finish to clear review and match the neighborhood.
Post Falls gets real Panhandle winters, so the roof has to carry a meaningful snow load, the foundation has to handle freeze-thaw, and the doors need to keep working after a heavy storm. We build to the roof pitch and anchoring the local load calls for and set most buildings on a gravel pad that drains snowmelt instead of trapping it against the structure. If you want the shed usable year-round as a shop, office, or studio, we can insulate and wire it to stay comfortable through the cold months.
