Permit costs and review times in Nampa
Permit fees and plan-review turnaround are set by Nampa, not by the contractor, and they differ across the Treasure Valley. They belong in your budget and your schedule from the start.
- How Nampa calculates the fee
- Valuation-based. Building-permit fee per the city's Schedule of Permit Fees: $369.69 for the first $25,000 + $9.55 per additional $1,000 (to $50k); $608.44 + $6.61 per $1,000 (to $100k); $938.94 + $5.29 per $1,000 (to $500k). Plan review is 65% of the building-permit fee. Trade (plumbing/mechanical/electrical) sub-permits are charged separately.
- Plan-review turnaround
- Allow 1–2 weeks to process an application after payment is submitted.

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.

Actual project scenarios we complete in Nampa, with the typical investment and timeline for each:
South Nampa Fiber Cement Repaint
$4,500–$7,5005–8 daysA 2005-2015 Nampa home with James Hardie or similar fiber cement siding showing chalking, fading, and peeling at cut edges after 10+ years on the original paint system. Proper scope includes pressure washing, repair of any damaged boards, caulking all horizontal joints and window/door perimeters, spot priming cut edges and bare substrate, and application of a 100% acrylic exterior paint specifically formulated for fiber cement application. Two full coats plus a primer coat at all repairs.
Northwest Nampa Wood Siding Full Repaint with Rot Repair
$5,500–$9,5007–12 daysA 1970s-1980s Northwest Nampa home with original wood or hardboard siding that is showing moisture damage in lower courses, paint peeling at windowsills and trim joints, and visible rot at corner boards and door/window casing bottoms. Scope includes rot assessment and repair (epoxy consolidant and filler for minor rot, board replacement for significant damage), power washing, scraping and sanding all loose paint, caulking all penetrations and joints, and applying a full two-coat exterior paint system with appropriate primer on all bare and repaired areas.
Downtown Nampa Historic Wood Siding Restoration
$8,500–$16,00010–18 daysA pre-1950 Downtown Nampa farmhouse or bungalow with original wood siding that has accumulated multiple paint layers and is showing widespread adhesion failure in areas. Assessment of lead paint presence, encapsulation or removal as required, scraping and sanding to sound substrate, spot priming, full repaint in a historically appropriate exterior palette. Detailed trim, corbels, porch railings, and other architectural elements receive careful brush application in a contrasting or complementary color.
Pre-Listing Exterior Refresh for Curb Appeal
$3,500–$6,5004–7 daysA Nampa homeowner preparing to list who needs to maximize curb appeal within a constrained timeline and budget. Scope focuses on the highest-visibility elements: full siding repaint in a contemporary color, fresh trim color, new front door color as an accent, and painting of any metal handrails or shutters. The goal is maximum photographic and in-person impact within a budget justified by the expected sale price improvement.
Rental Property Exterior Maintenance Repaint
$3,000–$5,5004–6 daysA Nampa investment property that needs exterior painting as part of regular maintenance — not distressed, but showing 7-10 years of weathering and beginning to show chalk and minor peeling at joints. Scope emphasizes surface cleaning, re-caulking of all joints and penetrations, and a full repaint with a durable, washable exterior product that will provide another 8-10 year service cycle with normal maintenance.
These are the factors that have the biggest impact on your exterior painting budget in Nampa. Understanding each one helps you make better decisions during the planning phase.
Home Size and Number of Stories
high impactThe total exterior surface area is the primary cost driver. A two-story home has significantly more paintable surface and requires ladder or scaffold access, which increases labor time and cost.
Surface Preparation Requirements
high impactHomes with extensive peeling, cracking, or deteriorated paint require much more prep work — scraping, sanding, caulking, and priming — which can represent 40-60% of total project labor.
Siding Material
medium impactWood lap siding, cedar shingles, fiber cement (HardiePlank), stucco, and vinyl each require different prep techniques, products, and application methods. Some materials require more coats or specialized primers.
Number of Colors and Trim Details
medium impactA single siding color with matching trim is the most efficient. Multiple body colors, contrasting trim, detailed millwork, and decorative elements require additional masking, cutting in, and paint changes.
Height and Access Challenges
medium impactTall peaks, steep rooflines, second-story soffits, and areas requiring scaffolding or lift equipment add labor time and equipment costs.
Wood Rot Repair
low impactDamaged or rotted trim, fascia, or siding discovered during prep needs to be repaired or replaced before painting. Rot repair costs vary from minor patching to full board replacement.

Exterior Painting in Nampa: housing stock, climate & permits →How much does it cost to paint a house exterior in Boise?
A full exterior repaint for a typical single-story home in the Treasure Valley runs $4,000-8,000. Two-story homes typically cost $7,000-14,000. Costs vary based on home size, surface condition, prep requirements, and paint quality.
Should I repaint or reside my home?
If your siding is structurally sound and the surface condition allows for proper prep, repainting is significantly more cost-effective than residing. If siding is rotted, warped, or damaged beyond repair, replacement may be the better long-term investment.
