Custom Bathroom, Kitchen & Historic Home Remodeling in Salt Lake City
Remodeling a historic or mid-century home in Salt Lake City, UT (84101–84108) typically invests $21,000–$48,000 for custom bathrooms, $58,000–$128,000 for structural kitchen renovations, and $65,000–$145,000 for basement finishing or ADUs. Urban Design & Remodel (Principal Grant Helmer, Utah DOPL #10146123-5501, (801) 440-1952) handles lath-and-plaster containment, PEX/PVC repiping, Schluter-KERDI waterproofing, and Salt Lake City Building Services permits.
From 1912 Craftsman bungalows in Sugar House and Liberty Wells to steep hillside Victorians in The Avenues and stately Tudors across Harvard-Yale and Federal Heights (4,220 to 5,150 feet across ZIP codes 84101–84108), Salt Lake City's classic neighborhoods demand far more than surface cosmetics. Behind century-old lath-and-plaster walls sit ungrounded knob-and-tube or cloth wiring, bell-hub cast-iron stacks, out-of-level rough-sawn joists notched by five generations of handymen, and cramped kitchens isolated from backyard light. Led by Principal Contractor Grant Helmer (DOPL #10146123-5501), Urban Design & Remodel marries historic architectural character with modern building science.
Period-Authentic Bathrooms with Invisible Modern Waterproofing
Remodeling a narrow 1920s bathroom in The Avenues, 9th & 9th, or Sugar House shouldn't erase your home's heritage—nor leave you nursing leaky clawfoot supply valves and crumbling grout. We strip heavy wire-mesh mortar beds and lath-and-plaster cleanly under negative-air HEPA containment, sister notched rough-sawn floor joists with engineered LVLs, replace galvanized risers and lead/cast-iron bends with PEX-A and Schedule 40 PVC, and wrap wet zones in 100% vapor-tight Schluter-KERDI membranes. Over DITRA-HEAT radiant cables, our tile craftsmen lay crisp unglazed porcelain hex mosaics, handmade-look glazed Zellige or bevel subway tile, custom furniture vanities, and EnduroShield 3/8-inch glass.
- Period-faithful hex, subway, and marble-look porcelain paired with stain-proof grout
- Curbless walk-in shower conversions and second-story primary suite additions over solid framing
- EnduroShield glass protection engineered for Salt Lake City's 11–16 GPG canyon/well water
Structural Kitchen Expansions in Tudors, Craftsmen & Brick Bungalows
Early-20th-century Salt Lake City homes tucked tiny 10x11 kitchens at the rear corner beside enclosed back porches and steep basement stairs. Opening that rear load-bearing brick or balloon-framed partition to create a sunlit chef's kitchen requires Utah PE-stamped seismic and vertical load engineering—transferring upper-floor and 30–48 psf roof loads safely down through concealed steel or LVL beams to new concrete spread footings in the basement. We pair restored quartersawn oak millwork profiles with custom inset painted maple or rift white-oak cabinetry, Soapstone, quartzite, or honed quartz countertops, and exterior-vented range hoods.
- Flush structural steel and LVL headers engineered for Salt Lake seismic Category D/E zones
- Custom inset cabinetry built to full 9-to-10-foot historic ceiling heights with library-rail options
- Complete 200-amp service upgrades replacing legacy ungrounded branch wiring
Historic Basement Dig-Outs, Finishing & Permitted SLC Internal ADUs
Sandstone, lime-mortar, and early board-formed concrete basements across Liberty Wells, Sugar House, and Yalecrest hold enormous untapped equity—especially since Salt Lake City expanded citywide internal Accessory Dwelling Unit (ADU) eligibility. We solve vintage basement challenges head-on: remediating efflorescence and moisture vapor, rerouting sprawling gravity-furnace sheet metal into compact high-velocity or mini-split zones, saw-cutting code IRC R310 egress window wells with decorative tiered retainers, replacing century-old under-slab cast-iron sewer laterals before pouring leveled toppings, and building 1-hour fire-separated basement apartments or family media lounges.
- Turnkey Salt Lake City internal ADU design, fire-rated ceiling separation & egress compliance
- Under-slab cast-iron main drain replacement in Schedule 40 PVC prior to finishing floors
- Closed-cell rim-joist air sealing stopping cold winter drafts across historic main-floor planks
SLC Building Services Permitting, Historic Districts & Dust Discipline
Navigating Salt Lake City Building Services (451 South State Street)—and Historic Landmark Commission (HLC) certificates of appropriateness when exterior windows or dormers change in The Avenues, University, or Yalecrest local historic districts—takes veteran local experience. Principal Contractor Grant Helmer coordinates architectural drawings, Orion portal electronic plan reviews, and city inspections seamlessly. On tight urban lots with narrow alleyways or permit-only street parking, our crews maintain spotless sites, EPA lead-safe dust isolation, and respectful neighbor communication.
- Electronic plan submission & inspection management via Salt Lake City Building Services
- Strict HLC historic-district sensitivity whenever exterior window/door openings are involved
- HEPA negative-air scrubbers and ZipWall containment protecting historic plaster & trim

Grant Helmer's Utah Field Pro-Tip (DOPL #10146123-5501)
In pre-1940 Sugar House and Avenues homes, plumbers decades ago often chopped massive V-notches right out of the middle of 2x8 bathroom floor joists to squeeze in 4-inch cast-iron toilet bends. Never lay large-format porcelain over bouncy vintage joists—we sister structural LVLs first so grout lines never crack.
Frequently Asked Questions: Bathroom And Home Remodeling Salt Lake City Ut
Do interior bathroom or kitchen remodels in The Avenues require Historic Landmark review?
Purely interior bathroom, kitchen, and basement remodels in Salt Lake City historic districts require standard SLC Building Services permits (plumbing, electrical, structural) rather than Historic Landmark Commission approval—unless you alter street-visible windows, doors, or rooflines.
Can you build a legal basement rental (ADU) in Sugar House or Liberty Wells?
Yes. Salt Lake City's updated ADU ordinance allows internal basement ADUs across most residential zones. We verify owner-occupancy rules, design code-compliant separate entries, egress windows, interconnected smoke/CO detection, and 1-hour fire separations.
How do you protect our home from plaster and lead dust in pre-1978 SLC houses?
Rock-hard lime plaster creates superfine silica dust when demolished carelessly. We seal doorways with ZipWall barriers, cap HVAC ducts, mist demolition zones, and run commercial HEPA negative-air scrubbers vented straight outdoors.
Can we keep original radiator heat when remodeling a Harvard-Yale or Avenues bathroom?
Yes! Cast-iron hot-water or steam radiators taking up precious wall space can either be restored and sandblasted, swapped for sleek European wall-hung hydronic towel-warming panels, or supplemented with electric DITRA-HEAT floor warming.
