ADU builder in Boise's North End
Building a backyard ADU in the North End means working inside Boise's local historic overlay. Smaller, period-compatible plans clear Historic Preservation review fastest — and that's the path we quote.

What an ADU build looks like in North End
The North End sits north of downtown in zip 83702, between the Boise River and the foothills. Much of the neighborhood west of Harrison Boulevard falls within Boise's North End Historic District (locally designated 1994, expanded 2004), which means an ADU project here triggers a Certificate of Appropriateness from the Historic Preservation Commission before the building permit.
Typical North End parcels are small, narrow lots from the 1900s–1930s — roughly 5,000 sq ft in the 50 ft × 100 ft to 50 ft × 122 ft range. Housing stock is dominated by Craftsman bungalows, Queen Anne cottages, and American Foursquares. Lot depth and rear-yard access vary block to block, so a parcel-level review is essential before plan selection.

Which Boise overlays apply in North End
Historic overlay
Much of the North End west of Harrison Boulevard sits inside the locally designated North End Historic District (1994, expanded 2004). Boise lists ADU construction explicitly as a project requiring a Certificate of Appropriateness, with or without exterior alterations. Administrative (Type 2) review is a 15-day staff review followed by a 10-day appeal window. Larger or non-conforming designs route to a Type 3 hearing in front of the Historic Preservation Commission, which meets the last Monday of each month.
ADU considerations
What actually matters on a North End ADU project
Plan on 4–8 weeks of added calendar time vs a non-historic Boise build to clear HPC review and the appeal window before the building permit can be pulled.
Exterior design has to reference the primary dwelling and the surrounding historic context — flat-roof contemporary plans tend to draw objections; period-compatible cottage and bungalow profiles clear review faster.
The 900 sq ft Boise ADU cap still applies, and smaller footprints (under 500 sq ft) move through Type 2 administrative review more cleanly than designs that approach the cap.
Mature street trees and tight rear setbacks limit crane access on some blocks — we walk the site before pricing the foundation and framing scope so the number on the contract is the number you pay.
Older sewer laterals and undersized electrical services are common on pre-1930s lots; the lot check flags either issue before the bid, not after framing.

Rent — verify per address
Boise-wide 1-bedroom medians sat in the $1,479–$1,503 range per Apartment List and RentCafe data in late 2025/early 2026. Zip-83702 apartment averages skew much higher because the dataset is dominated by new downtown high-rise inventory inside the same zip — a detached backyard ADU in the residential North End will not command those high-rise numbers. We model rent off the Boise-wide median and confirm against current comps for the exact address before any pro-forma goes on paper.

FAQ
North End ADU questions, answered
Do I need historic review for a North End ADU?
If your parcel sits inside the North End Historic District boundary, yes — Boise lists ADU construction as a project requiring a Certificate of Appropriateness even without exterior alterations. The Ada County parcel viewer and the city's Planning + Development Services counter can confirm whether your specific lot falls inside the overlay. We pull that data on the free lot check before any bid.
How much extra time does the Historic Preservation review add?
Plan on 4–8 weeks of calendar time on top of a typical Boise ADU permit timeline. Administrative (Type 2) review is a 15-day staff window followed by a 10-day appeal period before the building permit can be pulled. Designs that need a public hearing route to the HPC's monthly meeting (last Monday of the month), which adds further calendar time if you miss the agenda cutoff.
Which pre-approved plans actually clear HPC review here?
Smaller, cottage-profile plans — the Goldfinch (280 sq ft Type A studio) and Waxwing (396 sq ft Type B studio) — read as period-compatible and move through administrative review fastest. The Kingfisher (491 sq ft Type C one-bedroom) is workable when sited well. The full-size Kestrel two-bedroom is rarely a fit on a typical 5,000 sq ft North End lot because of footprint and HPC compatibility concerns.
Can I build a modern flat-roof ADU in the North End?
It's possible but rarely the right path. Boise's historic district guidelines require new construction to reference the primary dwelling's character — pitched roofs, traditional siding, and proportions consistent with the surrounding 1900s–1930s housing stock. A modern flat-roof plan typically routes to a Type 3 hearing in front of the Historic Preservation Commission and is more likely to come back with revision requests than a period-compatible profile.
Does the 900 sq ft Boise ADU cap apply here?
Yes. The 2023 Modern Zoning Code raised the detached ADU cap from 700 sq ft to 900 sq ft or 50% of the primary dwelling's living area, whichever is less — and that ceiling applies across Boise, including the North End. On a 5,000 sq ft historic lot with a 1,400 sq ft primary, the 50% rule typically becomes the binding constraint rather than the 900 sq ft hard cap.
Who actually builds the ADU?
Construction is performed by our licensed builder partner, Iron Crest Remodel (Idaho RCE-6681702), under the BoiseADU.com pre-approved-plan program. Same fixed-price contract, same Boise-based crews, same lot check before any bid.
