Kitchen & Bath Remodeling

Changing a kitchen or bath layout requires checking what supports the room and what passes beneath it. Before removing a wall, an engineer determines whether it carries gravity loads, resists lateral forces, or both. A new beam may concentrate loads at posts that require upgraded footings; a visually open plan cannot interrupt the roof-to-foundation load path.

Plumbing relocation on a slab typically involves locating existing drains and embedded utilities, then evaluating trenching, drain slope, and concrete repair. Original radiant tubing needs particular care. A crawlspace can provide routing access, but beams, joists, limited clearance, and existing sewer elevations still constrain the design. Vent connections and cleanout access belong in the plan, not in field improvisation.

Effective kitchen ventilation captures cooking pollutants at the source and exhausts them outdoors through a properly designed duct. Hood selection should consider appliance output, hood geometry, duct diameter, equivalent run length, noise, and available replacement air. High exhaust volumes can depressurize a tight house; evaluate make-up air requirements under the applicable mechanical code and check interactions with combustion appliances.

Induction cooking requires verifying the selected appliance’s electrical demand against a dwelling load calculation, not just counting empty panel spaces. Dedicated circuits, feeder capacity, service capacity, and potential load management should be reviewed before ordering equipment. Bathroom fans also need outdoor terminations, suitable controls, and duct routes that avoid excessive resistance or condensation problems.

A durable shower needs a continuous waterproofing system connected correctly to its drain, penetrations, and adjacent surfaces. Tile and grout are finishes, not the primary waterproof barrier. Specify compatible membranes and accessories, sloped substrates, protected niches, and inspection or testing requirements before tiling. Glass anchors must not compromise the completed waterproofing assembly.

A curbless shower requires enough depth for drainage slope and a flush transition without cutting structural framing casually. Recessed framing or a slab depression may be necessary, subject to engineering and existing conditions. Evaluate water containment beyond the shower entry, floor slip resistance, and reachable controls. CALGreen, Title 24 Part 11, establishes applicable water-efficiency requirements for fixtures; confirm compliant toilets, faucets, and showerheads during selection.

The 2025 Title 24 Part 6 Energy Code took effect January 1, 2026, and applies to permitted work according to its scope and applicable transition rules. Kitchen and bath alterations may trigger requirements for high-efficacy lighting, lighting controls, and affected building systems. Coordinate dimmers, occupancy or vacancy controls where required, fixture compatibility, and task lighting rather than treating code compliance as a final fixture substitution.

Local reach codes and electrification requirements vary and are actively changing. Heartwood confirms the current ordinance for each project, including whether the proposed alteration triggers electric-readiness provisions or other requirements. Evaluate induction circuits and future heat pump water heating alongside the existing service. Any necessary utility coordination should start early, particularly when equipment locations or service upgrades affect the site plan.

The sequence begins with existing-condition investigation and a coordinated layout, followed by selections, construction documents, permitting, and procurement. Confirm appliance specifications before cabinet drawings are approved. Review cabinet shop drawings, slab availability, specialty tile, and plumbing trim lead times before setting a demolition date; delivery estimates are not substitutes for verified release and production milestones.

Construction moves through protection and selective demolition, structural work where needed, rough plumbing and electrical, inspections, and wall closure. Waterproofing and required testing precede tile. Cabinet installation establishes final dimensions for countertop templating; fabrication follows field verification. Finish plumbing, appliance connections, lighting adjustments, ventilation checks, and a documented punch list complete the work. Plan temporary cooking facilities and continued bathroom access around actual shutoff periods.
