Homes From the 1970s and 1980s

Rowland Heights began as part of Rancho La Puente, granted to John Rowland in 1842. Wikipedia's history of the community says that when Rowland and William Workman divided the rancho in 1868, Rowland kept the sections that later became most of Rowland Heights, and the land stayed largely in orange groves until housing spread east from Los Angeles. It first appeared as a place of its own in the 1970 census.

On the median, its homes are newer than those in Hacienda Heights (1968) or South Whittier (1957). In the Census Bureau's 2020-2024 American Community Survey, the median home here dates from 1976, while the 1970s alone account for about 30 percent of the roughly 15,700 homes and the 1980s for close to 20 percent. A further 14 percent date from the 1990s, the decade in which, according to Wikipedia, the community grew significantly. About 72 percent of homes are detached houses, and roughly 15 percent are in buildings with five or more units.

For a bathroom, that profile means many homes could still have an original 1970s or 1980s shower. If yours has never been redone, the pan under its tile has been in place for something like 37 to 56 years. In a house finished before 1978, the EPA requires any firm paid to disturb painted surfaces to hold lead-safe certification. Indoors, minor repairs are exempt if no room has more than 6 square feet of paint disturbed, but replacing windows or demolishing painted surfaces is always covered. Close to a third of homes here predate 1970, and the 1970s houses fall on both sides of the 1978 cutoff, so it's worth confirming your home's build year before anything is torn out.

Tub Conversions, Walk-In Showers and Pans

Plumbing code sets two tests for the size of a shower: a floor of at least 1,024 square inches, and room for a 30-inch circle. A receptor of 30 by 60 inches is exempt from the area rule, and since most bathtubs in an alcove run 60 inches end to end, the space a tub leaves behind is normally big enough for a walk-in shower. A curb, if the new shower has one, must be between 2 and 9 inches tall, measured from the drain's top, and the shorter it is the easier it is to step over. Walk-in, curbless and replacement showers get a fuller treatment on the shower remodeling page.

The pan is the hidden layer that keeps water out of the subfloor. Code requires the shower floor to drop toward the drain by 1/8 inch per foot at the least and 1/2 inch per foot at the most. The 2025 edition of the state plumbing code (section 408.8.5) requires every site-built pan to pass a water test with the drain plugged, holding 2 inches of water or more for 15 minutes or longer. Once an aging pan begins to leak, the signs can show up away from the shower: stained trim, floor tiles working loose there or next door through the shared wall, or a stain on a ceiling below. Read how leaks get traced, and when fixing a pan beats replacing it, on our shower pan replacement and repair page.

Rowland Heights Permits and LA County Public Works

Rowland Heights isn't a city. The county lists it as an unincorporated area in Supervisorial District 1, which means building permits are issued by the Building and Safety Division of LA County Public Works. You can apply, upload plans, pay fees and book inspections online in EPIC-LA, the county's portal.

When the county's plan check would take no more than 15 minutes, staff may review the job at the counter in the morning. Complex work, or anything the Building Official chooses to accept for review, is taken in instead. Tile, cabinets and countertops don't need a building permit unless disabled access requirements come into it, yet the plumbing, electrical or mechanical side of the same remodel can still need a permit of its own. As examples, the county files a toilet replacement under its simple plumbing permits and a whole-house repipe under complex ones.

If work hasn't begun 12 months after the permit was issued, or it stops for longer than 180 days at any point, the permit expires, though a written request can win an extension of 180 days. Book each inspection on EPIC-LA a day or more ahead; inspectors work regular business hours.

No more express plumbing permits. As of 26 August 2026, EPIC-LA no longer issues express permits for plumbing, electrical, mechanical or sewer work. The county's guidance is to choose one of its Simple permit types instead, and that is where a straightforward toilet swap now goes.

Signs Your Shower Is Leaking

Stop using the shower until it has been checked. Every shower you take can push more water into the wall cavity or subfloor, and EPA guidance is to get wet materials dry within 24 to 48 hours, before mold can start.

Under an upstairs bathroom, check the ceiling for a water stain or a patch of newer paint. On the ground floor, look at the baseboard and the floor tile, both in the bathroom and in whatever room shares the shower wall. The trim plate around the shower valve can also be taken off and checked for water stains on its back. Grout that keeps cracking and a musty smell are other warnings.

Fixture Rules Under SB 407

California's SB 407 reaches back to homes built and available for use on or before January 1, 1994. The Census Bureau puts about 82 percent of Rowland Heights homes before 1990, and houses completed in the early 1990s can fall inside the cutoff as well. For those homes, a permitted alteration to a single-family house carries a condition: before the county gives final permit approval, the applicant must swap out fixtures the law counts as noncompliant, subject to its listed exemptions. That means toilets flushing more than 1.6 gallons, showerheads delivering more than 2.5 gallons per minute, and faucets indoors running above 2.2 gallons per minute.

Replacement fixtures have to satisfy CALGreen, which sets tighter caps: 1.28 gallons per flush, 1.8 gallons a minute for a showerhead and 1.2 for a lavatory faucet. Rowland Water District's conservation tips say that taking out an old 3.5- to 7-gallon toilet in favor of a 1.6-gallon one saves over 700 gallons a month. For rebates, the district names premium high-efficiency toilets on its list and directs customers to SoCal Water$mart, the Metropolitan program, whose toilet page lists $40 per toilet. To qualify, the new model has to be MaP-certified at 1.1 gallons per flush or under and take the place of a 1.6-gallon or larger toilet. Walnut Valley Water District points its customers to the same program, adding that Metropolitan requires device rebate applications within 12 months of purchase. SoCal Water$mart says rebate amounts may vary by water agency and depend on available funding, so look at socalwatersmart.com before the old toilet goes.

Bathroom Remodel Price Ranges

For 2026, published cost guides tracking prices across Los Angeles and Orange County put a whole-bathroom remodel at between $7,500 and $35,000. Nationally, the guides show a shower remodel or replacement running $800 to $15,000, converting a tub to a shower $1,200 to $12,000, and a replacement shower pan $300 to $4,600. Those are published market prices, not what we charge, and your free estimate is where the actual price for your room comes from. Ranges by room size and by job are on the bathroom remodel cost page.

Hard Water From Two Districts

Two water districts serve parts of Rowland Heights. Rowland Water District, formed by a community vote in 1953, serves portions of it along with parts of Hacienda Heights, La Puente, Industry and West Covina, and Walnut Valley Water District serves the easterly unincorporated area. Your bill shows which one is yours. Both buy treated water from the same two plants: Metropolitan's Weymouth plant in La Verne, which treats a blend of Colorado River and State Water Project water, and the Three Valleys Miramar plant in Claremont, which treats State Water Project water. Rowland's report also lists groundwater among its sources.

Hardness depends on the source. Rowland's 2023 water quality report lists averages of about 4.3 and 6 grains per gallon for its two treated surface supplies, and about 12.9 and 13.7 for its groundwater sources. Walnut Valley's 2025 report gives averages of 234 and 97 parts per million for its treated surface water, or about 13.7 and 5.7 grains per gallon. At the harder end, water leaves white spots on glass and a crust on showerheads and aerators. Choosing a fixed glass panel without a bottom track, and a showerhead you can unscrew for descaling, makes that easier to manage.
