Whole House Renovation in Nampa, Idaho

Full-Service Renovation Solutions for Idaho Homeowners
Nampa has been one of the Treasure Valley’s anchor communities for over a century, and the city’s older neighborhoods are filled with homes that have great bones and even better locations — but are long overdue for a complete renovation. At Eliezer Custom Homes, we provide comprehensive whole house renovation in Nampa, Idaho, transforming aging homes into modern, efficient, and beautiful living spaces. Whether you own a historic downtown Nampa property or a mid-century home on the city’s west side, we bring the expertise and craftsmanship to make it feel brand new.
Why Nampa Homeowners Are Choosing Renovation
Nampa’s housing market has shifted significantly in recent years. Property values across Canyon County have risen sharply, and many homeowners now find themselves sitting on valuable real estate in established neighborhoods — but living in homes that haven’t been meaningfully updated in 30, 40, or even 50 years.
At the same time, new construction in Nampa is concentrated in newer subdivisions on the city’s outskirts, where lot sizes are smaller and homes sit closer together. If you own an older Nampa home on a generous lot near downtown, near Lake Lowell, or in the established neighborhoods along 12th Avenue or Midway Road, a whole house renovation lets you keep the location and the lot while getting a home that meets today’s standards for comfort and efficiency.
For many Nampa families, renovating is also more affordable than purchasing a comparable updated home in the current market — especially when you factor in the equity you’ve already built in your property.

What We Find in Nampa’s Older Homes
Nampa’s housing stock spans a wide range of construction eras, and each comes with its own set of renovation challenges:
Downtown and Historic Nampa (1910s–1940s)
The neighborhoods surrounding downtown Nampa — along streets like 12th Avenue South, 2nd Street, and near Lakeview Park — include some of Canyon County’s oldest residential architecture. These homes often feature plaster walls, hardwood floors under layers of carpet, and charming period details. But behind those details, you’ll typically find:
- Outdated electrical systems: Knob-and-tube wiring or early Romex with undersized panels that can’t safely handle modern appliances, electronics, and air conditioning loads
- Failing plumbing: Galvanized steel supply pipes that have corroded from the inside, reducing water pressure and creating leak risks throughout the home
- No central HVAC: Many of these homes rely on floor furnaces, wall heaters, or aging boiler systems with no air conditioning — a serious comfort issue during Nampa’s 95-degree July and August days
- Minimal insulation: Drafty walls and uninsulated attics that make the home expensive to heat in winter and impossible to cool in summer
A whole house renovation addresses all of these issues at once — new electrical panel and wiring, replumbed water and drain lines, a modern high-efficiency HVAC system, and comprehensive insulation — while preserving the character elements worth saving.
Mid-Century Homes (1950s–1970s)
Nampa expanded significantly after World War II, and the city’s west and south sides filled with ranch-style and split-level homes during this period. These properties typically sit on half-acre or larger lots with mature landscaping and outbuildings. Common renovation needs include:
- Closed floor plans: Small, separated kitchens walled off from living areas. Opening these up into a modern open-concept layout is one of the most transformative changes we make.
- Single-bathroom homes: Many mid-century Nampa homes have just one bathroom for the entire household. Adding a master ensuite and a second bathroom dramatically improves daily livability.
- Baseboard or wall heat: Upgrading to a central forced-air heating and cooling system is a standard component of our whole house renovations in these homes.
- Original windows: Single-pane aluminum-frame windows that leak air year-round and drive up energy costs. Replacing them with modern double-pane vinyl or fiberglass windows is a night-and-day improvement in comfort and efficiency.
1980s–1990s Homes
Even homes from this era in Nampa are now 30 to 40 years old. Builder-grade finishes have worn out, carpet is well past its useful life, kitchens and bathrooms look dated, and the home’s major systems — water heaters, furnaces, roofing — are at or beyond their expected service life. A comprehensive renovation refreshes every surface and brings the home up to current Idaho energy code standards.
What a Nampa Whole House Renovation Includes
Every home is different, but a typical whole house renovation with Eliezer Custom Homes covers:

Structural assessment and repairs
We evaluate the foundation, framing, and roof structure before anything else. Older Nampa homes sometimes have foundation settling due to Canyon County’s expansive clay soils, and we address structural issues before any cosmetic work begins.

Complete mechanical system replacement
New electrical service and wiring, new copper or PEX plumbing throughout, and a modern HVAC system properly sized for your home’s square footage.

Insulation and weatherization
We bring your home up to current Idaho energy code standards with proper wall, attic, and crawl space insulation plus air sealing.

Floor plan reconfiguration
Opening walls, expanding rooms, and creating the flow that modern families need for how they actually live.

Full interior finishes
New flooring, drywall, trim, cabinetry, countertops, fixtures, lighting, and paint throughout every room.

Kitchen and bathroom redesign
Complete rebuilds of every kitchen and bathroom with modern layouts, quality materials, and updated plumbing and electrical.

Exterior updates
New siding, roofing, windows, doors, and entry improvements as the home requires.
Navigating Nampa’s Permitting Process
Whole house renovations in Nampa require permits from either the City of Nampa or Canyon County, depending on your property’s location and annexation status. We handle the entire permitting process on your behalf, including:
Building permit applications with detailed architectural and structural plans
Separate electrical, plumbing, and mechanical permits as required
Structural engineering documentation when load-bearing walls are removed or modified
Full coordination with city or county inspectors at each required stage of construction
Our familiarity with Nampa’s development services department and Canyon County’s building division means we understand what’s expected at every step. This experience translates directly into fewer delays, smoother inspections, and a project that stays on schedule.

Frequently Asked Questions
How much does a whole house renovation cost in Nampa?
Whole house renovations in Nampa typically range from $120,000 to $400,000 depending on the home’s size, age, and condition. Older downtown Nampa homes requiring foundation work, full mechanical system replacement, and structural modifications tend to be on the higher end. We provide a detailed, line-item estimate after assessing your home in person.
Is it worth renovating an older home in Nampa versus buying new?
In many cases, yes. Older Nampa homes often sit on larger lots in established neighborhoods with mature trees and convenient locations near downtown and Lake Lowell. A whole house renovation lets you keep those advantages while getting a home that functions like new construction. We help you evaluate whether renovation makes financial sense for your specific property.
What issues are common in older Nampa homes?
Common issues include outdated electrical systems that don’t meet modern code, galvanized or polybutylene plumbing prone to failure, inadequate insulation, single-pane windows, foundation settling from Canyon County’s expansive clay soils, and closed-off floor plans with undersized kitchens. A whole house renovation addresses all of these systematically.
Do you handle permits for Nampa renovations?
Yes, we handle all permitting through the City of Nampa or Canyon County, depending on your property’s location. This includes building permits, electrical permits, plumbing permits, and mechanical permits. We coordinate the full inspection schedule so your project stays on track and passes every inspection the first time.
