Quick answer
La Jolla is a community of the City of San Diego, so City of San Diego Public Utilities provides water and sewer and the city's Development Services Department issues plumbing permits. Owners are responsible for the sewer lateral all the way to the city main, and the city requires a pressure regulator where street pressure exceeds 80 psi. A water heater permit costs $122.97.

Is La Jolla its own city?
No. The City of San Diego's La Jolla Community Plan page describes La Jolla as a community planning area of about 5,718 acres along the western edge of the north coastal region of the City of San Diego, lying in Council Districts 1 and 2. The page notes that the community is 99 percent built out, so most construction is infill and remodeling. For plumbing that means City of San Diego rules apply: city water, city sewer and city permits.
How old are La Jolla homes?
Census Bureau survey data for 2020 to 2024 for ZIP code 92037 put the median year built at 1975; about 66 percent of homes predate 1980 and about 12 percent were built in 2000 or later (ACS table B25034 via Census Reporter). The city's plan page adds that until the mid 20th century La Jolla was mostly small summer cottages along the coast and in The Village. Original drain lines, sewer laterals and older supply piping are therefore common in remodel and repair work. Before accepting a repipe or lateral replacement quote, ask for camera footage or the failed section of pipe.
Who is responsible for the sewer lateral?
The city's meter, water pressure and plumbing system page says the property owner is responsible for maintaining the sewer lateral from the property all the way to the connection with the city sewer main, which may be in the street, on an easement or in a canyon. After clearing a lateral, a licensed plumber usually televises it. If the pipe is broken between the house and the property line, the owner repairs it. If the plumber finds a break or collapse beyond the property line, the plumber should call the city's Sewer Emergency Line at 619-515-3525 to file a Plumber's Report, and the city says it will investigate within 24 hours.
The city also recommends that home buyers get a licensed plumber's report on the lateral in addition to a standard home inspection. Roots and cooking grease are the leading causes of lateral spills. See our sewer line repair guide.
What about water pressure and hardness?
The same page says the California Plumbing Code requires a pressure regulator on your property if the pressure in your area exceeds 80 psi, and that regulators are the owner's responsibility. A sudden increase in pressure is most often a failing regulator. The city notes that pressure varies in different parts of the city depending on location and demand, and will test pressure at the nearest fire hydrant on request, so it is worth checking before replacing fixtures or a water heater. The city reports San Diego drinking water averages about 16 grains per gallon of hardness, which builds scale in water heaters.
Which permits apply to plumbing work?
The city's technical bulletin RESD-5-1 says a plumbing permit is required to install a water heater, and that it is inspected after installation. Under Information Bulletin 103, a residential water heater permit costs $122.97 and residential water or waste pipe repair or replacement costs $264.25 per dwelling unit. Water heaters must also be strapped against earthquakes; see our strapping guide.

Why did my bill jump?
The city's billing page lists more use, meter misreads, meter leaks and leaks on the property, and explains a 30 minute meter test. Single-family sewer charges are set from winter water use, so a winter leak can raise sewer costs for a year. Our water bill guide covers the details.
How do you check a contractor in La Jolla?
California licenses contractors statewide through the Contractors State License Board, so the check is the same in every city: get the license number, enter it in the CSLB license check, and confirm the status is active, the classification fits the job and the name matches the business you are dealing with. Work that needs a building permit must be done by a licensed contractor if you hire it out, and contractors must print the license number on bids and contracts. Our hiring guide covers contracts and deposit limits, and the cost guide helps you judge a quote.

Frequently asked questions
Is La Jolla part of the City of San Diego?
Yes. The City of San Diego's planning department describes La Jolla as a community planning area within the city, in Council Districts 1 and 2. Water and sewer come from City of San Diego Public Utilities, and plumbing permits come from the city's Development Services Department, not from a separate La Jolla government.
Who pays to fix a sewer lateral in La Jolla?
The City of San Diego says owners are responsible for the lateral from the house to the connection with the city main. The owner repairs breaks between the house and the property line. If a licensed plumber finds a break beyond the property line, the plumber files a Plumber's Report with the city's Sewer Emergency Line.
Do I need a pressure regulator?
The City of San Diego says the California Plumbing Code requires a water pressure regulator on your property where street pressure exceeds 80 psi, and that regulators are the owner's responsibility. If pressure suddenly rises, the regulator is the most common cause. The city will test pressure at the nearest hydrant on request.
