When the top units lose flow first, the riser is a suspect alongside the main. ### A leak in one apartment's ceiling Water from a riser joint can show up a floor below the leak. Tracing it can open a wall in one unit to fix pipe that serves several. ### A three-flat owner with rented units Replacing one stack at a time keeps the others in service. Units on the stack being cut over are without water only during that cutover. ### A house on a block of houses Single-family homes make up 13.1% of units here. A whole-house repipe in one of them is planned from the meter and main shutoff like any Chicago house. ## Services in South Shore ### Riser replacement Plumbing riser replacement in condo and apartment buildings, stack by stack in copper, with each unit's tie-in, the association's approval and the City permit planned before the first shutoff. ### Whole-house repiping Whole-house repiping replaces every hot and cold supply line from the main shutoff to the fixtures in the material the local code lists, then pressure tests it before the walls close. ### Two-flat repiping The shared basement main, both units' risers and branches, and a shutoff in each apartment, planned around two households and one cutover. ### Galvanized pipe replacement Galvanized pipe replacement swaps restricted steel supply pipe for copper, with code-listed transitions wherever old pipe stays and a flush after every cutover to clear loosened scale. ### Commercial repiping Commercial repiping for mixed-use buildings, small offices and restaurants, in copper, with the permit path, the shutoff windows and the business's hours settled before work starts. ### Lead service line replacement A full replacement of the buried water service from the main to the building, with the City's free programs checked first and the new line's basement tie-in planned with the piping it feeds. South Shore is where riser work and house repipes meet on the same map. One job can be a brick apartment building with stacked kitchens whose hot and cold risers are replaced floor by floor, with residents at home; the next can be a single-family house that needs every line from its basement main to its top-floor bath. City records put a number on the first kind. Since the Express Permit Program launched in late 2023, 14 plumbing permits for South Shore addresses include replacing risers in existing chases, tied with Austin for the most of any community area. [Chicago Lake Repiping](https://chicagolakerepiping.com/) offers and manages [riser replacement](https://chicagolakerepiping.com/riser-replacement/), [whole-house repiping](https://chicagolakerepiping.com/whole-house-repiping/) and [galvanized pipe replacement](https://chicagolakerepiping.com/galvanized-pipe-replacement/) here, with licensed and insured plumbing contractors, each holding a City of Chicago plumbing contractor license, doing the work. ## One stack at a time A riser is the vertical pipe that carries hot or cold water up through a building, feeding units stacked one above another. In a walk-up or courtyard building, each set of stacked kitchens or baths can have its own pair. When those risers are galvanized steel, they narrow from the inside like any steel pipe, and the units at the top of the stack feel it first because they sit highest and furthest along the run. Replacing them stack by stack is what keeps a building livable during the work. Each stack is isolated, drained and opened at the chase, new copper is run and joined at each floor’s branch, and the stack is pressure tested before the chase closes. A 2022 permit for a South Shore building with one unit per floor across three floors describes exactly that scope: remove and replace the plumbing supply risers. A 2019 permit covered repairing damaged galvanized supply “in unit and riser.” The useful upgrade at each floor is a shutoff where the branch leaves the riser, so a later repair in one unit does not take down the stack. ## Risers, branches and the basement main A building’s supply has three layers, and a riser job touches only the middle one unless the scope says otherwise. Below the risers sits the basement main that feeds them from the meter and main shutoff. Above them, inside each apartment, are the branches to each sink, tub and toilet. New copper risers fed by a corroded galvanized main still get only what the main delivers, and new risers feeding old galvanized branches leave the narrowest pipe in the building at the fixtures. So the walk-through traces all three before anything is priced. Where the main is steel, replacing it before or with the first stack keeps every new riser from inheriting its restriction. Where the branches are steel, the owner can replace them unit by unit while each stack is open, or leave them and have the quote list them as retained pipe. Both are honest scopes; the difference is that a riser-only job is a [partial repipe](https://chicagolakerepiping.com/partial-repiping/), and the paperwork should call it one. In a two- or three-flat, the [two-flat repiping](https://chicagolakerepiping.com/two-flat-repiping/) page covers the shared main in detail. ## Why a riser is drawn before it is replaced The City’s Express rules for riser work require a plumbing contractor’s drawing of the entire riser, in two dimensions or as an isometric diagram, with its size and material. That drawing is more than paperwork. It shows which units each stack serves, where it ties to the basement main, and where branch valves already exist, which is what decides the cutover plan and how many units lose water at each tie-in. The fee follows the units: $150 per dwelling unit for the piping, plus $150 per unit when risers in an existing chase are replaced. Express permits also forbid new or enlarged openings through walls or floors separating units, corridors or stairways, and require firestopping where new pipe passes through existing openings, so the new copper follows the old chase rather than a new path. A riser reroute is an alteration and goes to plan review. The [Chicago repiping permit guide](https://chicagolakerepiping.com/guide/chicago-repiping-permit/) covers both routes. ## Residents in place In South Shore, only 25.8% of occupied homes are owner-occupied, against 46.0% citywide. That makes the water-off windows the part of a riser job residents notice. Work runs with the stack drained only for cutovers, and the quote names each window in advance so the owner can tell residents ahead of time. Openings in occupied units are cut in clean rectangles at fittings and turns, and the quote says who closes them. Tiled walls are reached from the back where the chase allows. The [living through a repipe guide](https://chicagolakerepiping.com/guide/living-through-a-repipe/) covers what the days look like from inside a unit. ## South Shore’s buildings and permit record Of South Shore’s 30,761 housing units, 30.1% are in buildings of 20 or more units and 21.2% in buildings of two to four units, while 13.1% are detached houses, by the Census Bureau’s American Community Survey as compiled by the Chicago Metropolitan Agency for Planning. The stock is old: 46.1% of units predate 1940, against 38.8% citywide, and the median year built is 1944. Its designated Chicago Landmarks include the 6901 Oglesby Cooperative Apartment Building and the Kenna Apartments on 69th Street, apartment buildings of the kind that carry risers, alongside the Allan Miller House on Paxton Avenue and the South Shore Cultural Center on South Shore Drive. Since January 2019, 30 permits for South Shore addresses state outright that water supply piping was replaced, and since late 2023, 49 plumbing permits include piping repair or replacement, the third-highest count among the 77 community areas. Some describe single-family work: a 2020 permit to “replace all water pipes with copper pipes,” and a 2019 permit to replace stolen hot and cold water lines in a house. Permits count permitted work, not the condition of any one building. ## The houses between the apartment blocks A single-family repipe in South Shore follows the same Chicago rules as anywhere in the city. The walk-through starts at the meter and main shutoff, reads static pressure at a hose bibb and compares flow at the lowest and highest fixtures, because a weak top floor can come from the service line or a valve rather than the pipe. The new piping is copper, since the Chicago Plumbing Code lists no PEX for water distribution, and the owner living in a detached house may do their own plumbing under permit and inspection. Lead-Safe Chicago says a house built before 1986 has a high likelihood of a lead service line unless it was replaced; that line is a separate project, covered on the [lead service line replacement](https://chicagolakerepiping.com/lead-service-line-replacement/) page. The [low water pressure guide](https://chicagolakerepiping.com/guide/low-water-pressure-old-chicago-house/) sorts out the possible causes, and [Greater Grand Crossing](https://chicagolakerepiping.com/service-areas/greater-grand-crossing/), to the west, shares the Grand Crossing neighborhood. ## Neighborhoods and coverage - South Shore - Grand Crossing ### Landmarks - South Shore Cultural Center, 7059 South Shore Dr - 6901 Oglesby Cooperative Apartment Building, 6901 S Oglesby Ave - Kenna Apartments, 2214 E 69th St - Allan Miller House, 7121 S Paxton Ave 1. 1.

Under the City's Express Permit Program, the plumbing fee is $150 per dwelling unit plus $150 per unit when risers in an existing chase are replaced, so a three-flat pays both amounts for each of its three units, and $75 more for each replaced water heater. A job that reroutes or extends piping goes to plan review, starting with a $600 deposit. The riser work itself is priced on stack count, height and access. ### Can residents of a South Shore building keep water while risers are replaced? Mostly, yes. Where each stack has its own valves, one riser is drained and replaced while the others stay in service, so only the units on that stack lose water, and only during its cutover. Where the risers share a single basement valve, the building goes off for each tie-in, and the quote should say when. ### Do South Shore co-op buildings need the same approval as condos? The City's Express rules call for a signed association approval letter for work on condominium property, including inside a unit. A cooperative is run by its own board, and its approval process is set by the co-op's own documents. Either way, a riser job also needs the contractor's drawing of the entire riser. ### Will new risers fix low pressure on the top floor of a South Shore walk-up? Only if the risers are the restriction. Top-floor units feel any loss first, and the cause can be the service line, the basement main, a partly closed valve or a failing pressure-reducing valve as well as narrowed galvanized risers. Measuring static pressure and comparing flow at the lowest and highest fixtures shows which before risers are priced. ### Does a riser replacement in South Shore include the pipes inside each apartment? Not unless the scope says so. A riser job replaces the vertical stacks and the valves where each unit branches off. The branches inside each apartment can be replaced at the same time or left, and if they stay, the quote should list them as retained pipe with a transition at each valve. ## Related guides - Learn [Do you need a permit to repipe a house in Chicago?](https://chicagolakerepiping.com/guide/chicago-repiping-permit/)What the Department of Buildings' Express permit covers when repiping a Chicago building, what pushes a job into plan review, the documents a riser or condo job needs, and what the suburbs do differently. - Learn [Why is the water pressure low in my old Chicago house?](https://chicagolakerepiping.com/guide/low-water-pressure-old-chicago-house/)Weak water flow upstairs has more than one possible cause, and a repipe only fixes one of them.
