Most White Oak houses date from around 1955, and two or three bedrooms is the norm. When yours finally runs out of room, our carpenters work from the borough's yard limits and how your lot falls away, and frame new space the next occupancy inspector will sign off on.
White Oak Additions
Half the borough's houses were standing by 1955. Two bedrooms or fewer is the case in about 40% of them, and owners past 65 hold roughly half. Those numbers explain most of the additions we're asked for.
People past 65 head about half the borough's owned homes, and a quarter are 75 or older. If the bedrooms are all upstairs, the stairs eventually decide things, and most would sooner build than sell.
A ground-floor bedroom with its own bath and closet at the back, a no-threshold shower and a built-in seat. Blocking for rails goes into the walls now, a switch sits beside the bed, and the new floor sits level with the kitchen's.
Primary suite additionsAbout 40% of houses here stop at two bedrooms. A baby on the way, a teen who wants privacy, or a relative moving in is usually what starts the talk about a third.
A ground-level bedroom off the back, or one upstairs over a new den, set at the old ceiling and floor heights. It gets the smoke alarm White Oak's occupancy checklist asks for in every bedroom.
Room additionsPostwar kitchens here can be tight: one cook, a little table, not much else. Families who host want a few more feet, enough for a center island, pantry shelving or a table that seats the whole crowd.
The back wall moves outward a few feet on proper footings, a header sized for the load replaces the old wall, and the floor runs through at one level. Cabinets and counters fill the new length, and the outside matches the house.
Bump-outsSome owners with yard to spare want a detached garage, and a few hope to put a bedroom or office over it. The zoning answers that one quickly: a detached garage may not contain living space.
The garage stays a garage, sited at least 3 feet off neighboring lot lines and 5 feet from an alley, no more than 18 feet tall. Extra living space, if you need it, goes into an addition on the house.
Garage buildsWhite Oak looks at porches during the occupancy inspection it holds before each change of occupant. Owners adding a covered back porch want it right the first time, so it never holds up a sale.
Guards where the drop requires them, a handrail you can grip on every stair run of four or more, and wood that's treated or sealed, as the checklist wants. The roof frames into the house wall, and the posts stand on footings.
Sunrooms and porchesIn March 2022 a slide closed a stretch of Lincoln Way, and Center Street Extension has stayed closed since slides in 2013. Owners on hillside lots ask what White Oak needs before they can dig.
On ground the county maps as landslide-prone, a geotechnical engineer investigates and seals a report, and the borough wants any hazard fixed before it issues the permit. We get that engineer involved before the design.
What we check firstCensus figures: ACS 2020–2024, rounded. Yard, garage and slope rules: the borough's zoning code, Part 13.
The rest of the job
How it runs, what it costs and who builds it are on our main additions & adus page.
Adding On in the Borough
Three things govern a White Oak addition: the paperwork, which pairs a zoning certificate with the building permit; the yard rules for your district; and an engineer's sealed report on mapped landslide ground.
ZoningGoes in with each permit application
Each White Oak building permit travels with a zoning certificate request, and a bathroom in the addition adds the county's plumbing permit. Our kitchen page for White Oak covers both. Drawings and filings are ours to handle.
White Oak permits, explained25%Building coverage cap in R-1
In R-1, the front yard is 40 feet, side yards total 30 with 10 or more on each, the rear is 30, and buildings may cover 25% of the lot. R-2 sets 30 in front, 20 combined at the sides with 7.5 minimum, 25 at the back, and 30% coverage. Houses are capped at 35 feet.
White Oak permits and zoning (opens in a new tab)SealedGeotechnical report, landslide areas
Where Allegheny County rates the ground hazardous or very hazardous for slides, White Oak wants a Pennsylvania-registered geotechnical engineer's signed, sealed report submitted with grading plans, and any problem it finds corrected before grading or building permits go out.
Slides in White OakAddition Questions
Five things White Oak owners want answered before design starts. How construction unfolds is laid out on the additions and ADUs service page.
Ask a QuestionGround conditions and size, mainly. A modest ground-floor room on level land is the simple job; a sealed engineering report for slide-prone ground, a second level or a new bathroom raise it. We price it on paper after a visit.
Addition price rangesOnly in one part of town. The zoning allows a house more than 40 years old to be converted for two or more families in the Lincoln Way Transitional Zone, with 6,000 square feet of lot per family in R-2. Outside it, rooms for a parent stay part of your household.
In-law suitesYes, one, and it needs a permit. A shed here can be up to 144 square feet, 12 feet on any side and 9 and a half feet tall, set in the rear yard 3 feet from the lines. Anything larger counts as a garage.
Garage buildsWorth checking. DEP shows confirmed workings beneath over half the borough, and standard home policies don't pay for subsidence. Look up the parcel and price the state's mine subsidence coverage while plans are in draft.
Mining in White OakYes, as part of the whole house. White Oak inspects before every change of occupant, owners included, and checks for smoke alarms in bedrooms and on every floor, rails on stairs of four or more steps, and sound porches. That list guides our work from the start.
