BATHROOM REMODELING IN ENCINITAS, CA

Before you contact Development Services, it helps to know which of these your project includes:

• Finish work, such as paint, a new mirror or new towel bars. Do not assume no permit is needed; ask the city.
• Fixtures replaced where they are, such as a toilet, faucet or showerhead. Ask whether the swap needs a permit and, if so, which application it goes on.
• Plumbing that moves: a relocated drain, a rebuilt shower with a new valve, or a tub-to-shower conversion. Plan on a permit.
• New electrical or ventilation work, such as a heated floor, added outlets, new lighting, or an exhaust fan and its duct.
• Accessibility changes, such as a curbless shower, a wider doorway or grab bars. Put them on the drawings from the start, since a curbless shower changes the floor and the drain.

A bathroom is where California's water-conservation law shows up most directly. Civil Code Section 1101.4, added by SB 407 in 2009, says that for building alterations or improvements to a single-family home built on or before January 1, 1994, replacing noncompliant plumbing fixtures with water-conserving ones is a condition of final permit approval. Section 1101.3 defines what counts as noncompliant:

• A toilet that uses more than 1.6 gallons per flush.
• A showerhead with a flow capacity of more than 2.5 gallons per minute.
• An interior faucet that emits more than 2.2 gallons per minute.

Two other state codes apply as well. The 2025 Energy Code (Title 24, Part 6), in effect for permit applications from January 1, 2026, has residential lighting rules in Section 150.0(k): new installed lighting is to be high efficacy, and at least one installed luminaire in each bathroom is controlled by an occupancy or vacancy sensor that turns it off automatically. The 2025 California Electrical Code calls for ground-fault (GFCI) protection on bathroom receptacles, and bathroom receptacles are supplied by a 20-amp branch circuit.

An exhaust fan, a relocated shower valve or a new circuit can each bring their own permit and inspection. What applies to your bathroom is decided by the city at plan check and inspection, so confirm with the city.

HCD's summary of the 2025 CALGreen code says bathroom exhaust fans are to be ENERGY STAR compliant and ducted to terminate outside the building, with a humidity control unless the fan is part of a whole-house ventilation system. By that summary, CALGreen reaches alterations that add conditioned area, volume or size, so ask the plan checker whether it applies to a fan replaced inside an existing bathroom.

The Energy Commission's 2025 Single-Family Residential Compliance Manual adds that lighting built into an exhaust fan must be controlled independently from the fan.

If the shower is rebuilt or a tub is converted, ask the city which inspections your permit includes and when to call for each one. Plan the tile schedule around them so finishes do not cover work an inspector still needs to see.

Which inspections a bathroom permit includes is the city's decision. Confirm with Development Services before the walls are closed.

If you are thinking about a graywater system as part of the project, the city's Building pages include one titled Graywater Systems. Read it and ask Development Services what such a system needs before the new plumbing is laid out.

A bathroom remodeled inside the existing house adds no floor area, but adding a bathroom in new floor area is a different matter near the coast. Public Resources Code Section 30610 exempts improvements to existing single-family homes from a coastal development permit, and the Coastal Commission's regulation, Title 14, Section 13250, lists exceptions. They include improvements on a beach or within 50 feet of the edge of a coastal bluff, and adding 10 percent or more to the internal floor area of a home between the sea and the first public road, or within 300 feet of the inland extent of a beach.

Encinitas has a Local Coastal Program page under Policy Planning and a municipal code chapter titled Coastal Development Permit (Chapter 30.80). The Coastal Commission's Coastal Zone Boundary maps are a place to start, though the Commission cautions that the digital version “may not eliminate the need for a formal boundary determination.”

If your home is in a homeowners association that requires approval for physical changes, Civil Code Section 4765 sets the ground rules for that review: the association's decision is to be in writing, and a disapproval has to explain why and describe how to ask for reconsideration. HOA approval and a city permit are separate. One does not replace the other.
