Home Additions in Bergen County, NJ
Adding on in Bergen County is usually the right answer when the house is in the right town and the wrong shape. Rather than move and pay transfer costs, buyers' premiums, and a higher tax base, most of our clients would rather add the family room, primary suite, or second story the house should have had.
Strong Construction LLC designs and builds additions across Bergen County. We start with zoning feasibility, produce a permit-ready design with sealed structural drawings, price the work in writing, and build with our own crews under one contract.
Zoning feasibility before design
Every Bergen County town restricts what you can add through setbacks, building coverage, impervious coverage, floor area ratio, and height. Some towns also limit second-story additions on nonconforming lots or require a variance if the existing house already sits inside a setback. We pull the zoning schedule for your specific district, measure the lot, and tell you what fits by right before anyone pays for a full design. When a variance is genuinely worth pursuing, we prepare the application package and work with your land-use attorney and planner through the board hearing.
Additions that look original, not attached
The difference between a good addition and an obvious one is in the details: matching roof pitch and overhang, aligning window heads and sill heights with the existing house, continuing the siding exposure and corner detail, and carrying interior trim profiles and floor direction through the transition. We also plan the connection point carefully so the new space does not create a dark, awkward hallway inside the original house. Frequently the best move is to renovate a small area of the existing home at the seam so the plan reads as one house.
Structure, foundations, and systems
Additions are engineering projects. New footings and foundation walls have to be sized for the soil and frost depth, tied to the existing structure appropriately, and inspected before backfill. Second-story additions require verification that the existing foundation and framing can carry the new load, and frequently a new beam line and columns down through the house. Heating and cooling capacity, electrical service size, and plumbing venting all need to be evaluated rather than assumed. We include those upgrades in the proposal instead of leaving them as surprises.
Written pricing and a real schedule
Bergen County additions typically run $350 to $600 per square foot for finished conditioned space, with primary suites and kitchen-containing additions at the higher end and simple family room bump-outs lower. A two-story addition over an existing footprint often costs less per square foot than an equivalent single-story addition because it shares the foundation and roof. You receive a line-item proposal covering site work, foundation, framing, roofing, siding, windows, insulation, mechanicals, drywall, trim, flooring, paint, and final clean, with dollar allowances for selections. Design and permitting typically take two to four months, and construction four to eight.
Working in Bergen County
We file additions with township construction offices throughout the county, including Ridgewood, Franklin Lakes, Upper Saddle River, Saddle River, Tenafly, Wyckoff, Glen Rock, Fort Lee, and Englewood Cliffs. Each has its own zoning schedule and its own appetite for variances, and several require soil erosion control approval or county planning board review for work near a county road. Homes near the Saddle River, Ho-Ho-Kus Brook, and Hackensack River may sit in mapped flood areas that affect foundation and elevation requirements. We resolve all of this during feasibility so your schedule is built on approvals we can actually obtain.

Frequently Asked Questions
How much does a home addition cost in Bergen County?
Finished conditioned additions generally run $350 to $600 per square foot depending on complexity, with kitchens, primary suites, and difficult site access at the higher end. Second-story additions over an existing footprint are often more efficient per square foot than ground-level additions.
Will I need a zoning variance?
Not always. Many additions fit within setbacks and coverage limits by right. We check your lot against the zoning schedule first, and if a variance is required we prepare the application and support the hearing rather than abandoning the design.
Do you handle permits and inspections?
Yes. We pull the building, plumbing, electrical, and fire permits, coordinate the plan review with the local construction office, and meet every inspector on site. You never have to sit in a municipal office or chase a subcode official. Our license and insurance certificates are filed with the township before we start.
How long will the work take?
A kitchen typically runs eight to twelve weeks on site once materials are in hand, a bathroom four to six weeks, and a whole-home renovation four to eight months depending on structural work. We order cabinetry and stone before demolition so your home is not sitting open waiting on a delivery.
