Our streamlined design-build process ensures your lower-level renovation is completed on time, within budget, and to the highest municipal building codes in Salt Lake County.

Our Streamlined Finishing Process:

Before we discuss remodeling costs, here is how our local Utah team brings your vision to life:

1. Floorplan Design & Consultation: We evaluate your unfinished square footage, discuss your goals, and create a 3D layout to maximize your space.
2. Engineering & Permitting: We pull all necessary Salt Lake County municipal permits, ensuring structural modifications and electrical plans are fully approved.
3. Rough Construction & Sub-Surface Plumbing: We handle the heavy lifting, including concrete trenching for ejector pumps, HVAC zoning, and pre-wiring for A/V and smart home integration.
4. Drywall & Custom Finishes: From moisture-resistant green board to custom cabinetry and tile, our expert craftsmen ensure every detail passes final inspection.

Navigating Herriman Building Permits and Itemized Bids

When planning a lower-level remodel, working with a licensed general contractor is essential to protect your home and your budget. Herriman City and Salt Lake County require strict building permits for structural changes, electrical upgrades, and plumbing additions. We handle all coordination with the local building department, ensuring your project passes every municipal inspection without costly delays. Furthermore, we believe in complete financial transparency. Rather than vague estimates, we provide detailed, itemized bids that break down labor, building materials, and timeline expectations. This approach protects you from hidden fees and unexpected change orders mid-project. In the 2026 Utah market, standard basement finishes typically start around $40 to $55 per square foot, while custom apartments or intricate home theaters range from $55 to $100+ per square foot depending on your specific layout and premium finishes.

Maximizing Your Return on Investment (ROI)

Finishing your basement is widely considered one of the highest ROI home improvements you can make in the South Valley. Instead of facing the highly competitive housing market to find a larger property, expanding your current footprint is highly cost-effective. Whether you are adding legal bedrooms for a growing family or constructing a fully independent mother-in-law suite for passive rental income, this strategic investment significantly boosts your overall property appraisal. By utilizing durable, moisture-resistant materials and adhering to local zoning laws, we ensure your new square footage adds lasting value to your home.

Average Pricing for Basement Renovations in Utah

Every home is unique, but we want you to have a realistic baseline before you start. Based on current material and labor rates in the Salt Lake market, here are the average cost ranges for our primary lower-level services:

• Basement Apartments & ADUs ($45,000 - $85,000+): Building a complete secondary suite with a kitchen, living area, and legal bedrooms typically ranges from $40 to $60+ per square foot depending on finishes. This investment easily pays for itself by boosting your property value and creating passive rental income.
• Custom Home Theaters ($15,000 - $35,000): For a dedicated home cinema featuring tiered seating platforms, acoustic soundproofing, and custom A/V wiring, costs vary based on the level of technology and custom built-ins you choose.
• Basement Bathroom Additions ($12,000 - $22,000): Adding a new sub-surface bathroom requires specialized plumbing rough-ins and concrete cutting. The final price depends on whether you are building a simple half-bath or a luxury walk-in shower.
• Custom Wet Bars & Kitchenettes ($6,000 - $15,000): Elevating your entertainment space with custom cabinetry, quartz countertops, and built-in appliance integration is a highly sought-after feature for Utah homebuyers.
