Most Garden City projects: $19,500
Garden City siding costs reflect the city's compact urban lot sizes (generally smaller than suburban counterparts), diverse building types, and the river-moisture material specifications that most projects warrant. Standard residential fiber cement replacement on a Garden City single-family home runs $14,000–$22,000. Mixed-use, live-work, or converted structures with non-standard profiles and higher access complexity run $18,000–$40,000. Projects requiring moisture remediation behind siding on river-adjacent properties — not uncommon — add $3,000–$8,000. The compact lot sizes in Garden City can limit scaffolding access, which adds $1,000–$2,500 for work on second-story elevations where access is restricted.
Permit costs and review times in Garden City
Permit fees and plan-review turnaround are set by Garden City, not by the contractor, and they differ across the Treasure Valley. They belong in your budget and your schedule from the start.
- How Garden City calculates the fee
- Valuation-based (ICC Building Valuation Data or actual project cost, whichever is greater). Example base tiers: $2,000–$25,000 = $150 + $17.08 per additional $1,000; $25,000–$100,000 = $542.84 + $12.32 per $1,000. Residential plan review is 50% of the permit fee for projects over $20,000 (or $155/hour under $20,000).
- Plan-review turnaround
- Building permits require 10–15 working days to review (commercial with structural review at least 21 days). Re-submittals restart the review clock.

Idaho adopts building codes by statute, so the code editions are the same statewide — the 2018 IRC with Idaho amendments and the 2023 NEC. What changes between cities is the fee formula, the review queue, and which office holds the file.
The cost of siding installation in Garden City depends on the scope of work, materials selected, complexity of the layout, condition of existing systems, and the finish level you choose. Every project is different, but understanding the major cost drivers helps you plan a realistic budget and make informed decisions about where to invest and where to save. The ranges above reflect the full spectrum of projects we complete in Garden City — from straightforward updates to comprehensive renovations with premium materials and significant structural changes.
Actual project scenarios we complete in Garden City, with the typical investment and timeline for each:
River-Adjacent Home — Moisture-Resistant System with Anti-Algae Profile
$16,000–$26,0002–3 weeksThe most characteristic Garden City siding project involves properties within two to three blocks of the Boise River greenbelt, where the ambient moisture and biological growth environment demands the most rigorous material and installation specifications. These projects specify James Hardie fiber cement exclusively — the inorganic substrate provides no organic base for algae or mold colonization, and the ColorPlus finish system provides a closed surface that resists moisture absorption and biological adhesion. Smooth profiles (standard HardiePlank without deep wood-grain embossing) are specified for cleanability — cottonwood season cleaning is a practical annual reality, and smooth surfaces make this far more manageable than deeply textured profiles. Housewrap installation is specified to full drainage-plane standards, with attention to the slightly higher ambient moisture of the river environment.
Converted Live-Work Structure — Custom Profile and Urban Industrial Aesthetic
$18,000–$40,0002–5 weeksGarden City's Live-Work-Create district contains structures that began as light industrial or commercial buildings and have been converted — fully or partially — to residential or mixed use. These buildings often have non-standard exterior profiles: exposed metal, corrugated panels, or legacy commercial siding systems that are now at the end of their functional life. Siding replacement on these structures is as much an aesthetic decision as a functional one — the converted industrial aesthetic that defines Garden City's design identity often incorporates materials (corten steel panels, raw fiber cement, painted metal accents) that are not standard residential siding products. Iron Crest approaches these projects with the installation versatility and product knowledge to execute non-standard exterior systems while ensuring that the underlying moisture management and structural protection standards are met.
Greenbelt Corridor Cottage — Period Character with Modern Performance
$14,000–$22,0002–3 weeksThe residential blocks immediately adjacent to the Boise River greenbelt in Garden City contain a mix of modest cottages and bungalows from the 1940s through 1970s that are among the most charming small-residential properties in the Treasure Valley. The combination of their proximity to the greenbelt, their older architectural character, and the creative ownership demographic that has been drawn to this corridor makes siding replacement a careful balancing act: the project must preserve the home's architectural identity while delivering modern moisture protection appropriate to the river environment. James Hardie HardiePlank in 4-to-6-inch exposure widths reproduces the original lap profile of these cottages in a substrate that handles the greenbelt moisture environment without the organic vulnerability of the original wood. Period-appropriate colors — muted blues, sage greens, warm whites — read authentically in the greenbelt setting.
Garden City Core Infill Home — Contemporary Design in Urban Context
$14,000–$24,0002–3 weeksGarden City's newer infill residential development — homes built since 2000 on available lots in the city's compact urban grid — occupies a design space that is distinct from both the river-adjacent cottages and the converted industrial structures. These homes are often designed with more contemporary sensibility than suburban production homes, reflecting the design-aware culture of Garden City's ownership demographic. Siding on these homes is frequently LP SmartSide in a higher-spec profile from original construction, and replacement projects are primarily design-upgrade motivated: transitioning from a standard builder palette to a more expressive contemporary aesthetic with mixed profiles and bold dark colors. The compact urban lots that characterize Garden City infill development require installation crews comfortable with tight clearances and working in the proximity of neighboring structures.
Garden City Exterior Moisture Remediation and Re-Side
$12,000–$28,0002–4 weeksA subset of Garden City siding projects involves homes where the river microclimate has contributed to moisture infiltration through siding installation deficiencies that are more typical of the river environment than of drier Treasure Valley locations. These projects involve investigation of moisture-related conditions — staining, paint bubbling, soft spots in the wall assembly — followed by siding removal, substrate assessment and remediation, and installation of a new moisture management system with particular attention to drainage plane continuity and river-side exposure details. The investigation phase on these projects is critical and is priced separately from remediation and re-siding — the cost of remediation depends entirely on what the investigation reveals.
These are the factors that have the biggest impact on your siding budget in Garden City. Understanding each one helps you make better decisions during the planning phase.
Siding Material Selection
high impactThe material choice is the largest cost variable. Vinyl is the least expensive at $5-10/sq ft installed, LP SmartSide is mid-range at $8-13/sq ft, and James Hardie fiber cement is the premium option at $10-16/sq ft installed.
Home Size and Exterior Surface Area
high impactThe total square footage of siding surface — determined by the home's footprint, number of stories, and architectural complexity — is the primary quantity driver. A two-story home has significantly more surface area than a single-story.
Old Siding Removal and Disposal
medium impactRemoving existing siding, especially multiple layers or materials with asbestos content in older homes, adds labor and disposal costs. Single-layer vinyl removal is fast; multi-layer or cement-asbestos removal is slower and more costly.
Sheathing and Framing Repair
medium impactDamaged or rotted sheathing and framing discovered after old siding removal must be repaired before new siding goes on. The extent of hidden damage is often unknown until the old siding comes off.
Trim and Detail Complexity
medium impactHomes with many windows, doors, corners, gables, and decorative trim elements require more cutting, fitting, and finish work. Simpler facades with fewer interruptions install faster and cost less.
Window and Door Flashing
low impactProper flashing around every window, door, and penetration is essential for preventing water intrusion. The number and size of openings directly affects flashing material and labor costs.
