ADU Construction in Temple City
Temple City ADUs and garage conversions placed around the sewer lateral, panel and meters, drawn for permit review and built to the approved set.
The sewer lateral leaving your house has a depth and a direction, and on a Temple City lot those details can settle where a backyard unit is able to sit. A new bathroom has to drain downhill to that line, so a unit placed far from it may need a deep trench or a pump. We locate the cleanout, scope the pipe with a camera, and then draw the unit, file it for permit review and build to the approved set.
Finding the line before drawing the unit
A camera pushed through the cleanout shows the pipe's material, its condition and roughly how deep it runs near the property line. Clay or cast iron that has cracked or collected roots is worth replacing while the trench is open, since a new unit adds flow to it. If the rear of the yard sits lower than the lateral, gravity will not carry waste out, and a small ejector pump goes into the design. We also note the water meter and the gas service, because short, straight runs from each keep the unit close to where the utilities already are.
Power, wall openings and roof water
With the sewer route set, we turn to the electrical panel. We total what the house already draws and work out whether a subpanel fed from it can carry a kitchen, a bath fan and a heat pump, or whether the service needs an upgrade first. Every pipe and wire that passes through the new walls gets a molded boot lapped under the weather barrier, because inland sun and dry wind wear down exposed sealant. Roof water goes to a drain line kept away from the sewer trench, so it does not soak the fresh backfill and make it settle.
ADU Construction in Temple City: questions
Mark the setbacks on a survey, add the main house and any garage, and the remaining yard is the starting footprint. Then the utilities pull on it. A unit near the sewer lateral and the panel keeps trenching short, while one at the far corner may need a pump or a longer feeder. We sketch the layouts that work for detached, attached and garage options.
A Temple City reviewer checks how the unit's bathroom drains reach the existing lateral, so our site plan dimensions that run next to each setback, and the floor plan shows where every fixture sits. Both belong to our set for a single-story ADU of 500 square feet or less. If the lot needs unusual engineering, such as a pump design, that work is quoted on its own.
When the slab, framing and headroom hold up, it usually can. A garage at the back of the lot may sit far from the sewer line, so we check whether a new toilet and shower can drain by gravity, then probe the concrete for cracks and damp. You see those results before we recommend a path, with a written figure for converting next to one for building new.
