Home Remodeling in Middlesex County, NJ
Kitchens, bathrooms, basements, sunrooms, pergolas, decks, and full additions — designed and built across Middlesex County by a local, owner-led team based right here in Old Bridge.
Remodeling Services We Offer in Middlesex County
Middlesex County did most of its growing between 1950 and 1980, and that one fact explains most of the remodeling work here: capes, ranches and split-levels built for a family of four in 1962, with one full bathroom, an original kitchen and a full unfinished basement underneath. Legion Build is a design-build remodeler, which means one company designs the job, pulls the permits and builds it. Whatever you are planning, you deal with Adam from the first site visit through the final inspection.
Kitchen Remodeling
Layout changes, cabinetry, counters and full gut renovations — including the wall and plumbing moves that make an older Middlesex kitchen work like a new one.
Bathroom Remodeling
Full bath renovations, walk-in showers and tub-to-shower conversions, with the waterproofing and ventilation done properly the first time.
Basement Finishing
The cheapest usable square footage most Middlesex homes can add. Framing, egress, moisture control, bathrooms and wet bars, finished to code.
Home Additions
First-floor bump-outs, in-law suites and full second stories — designed to your lot, because coverage limits often decide whether you build out or up.
Custom Decks
Composite and cedar decks, multi-level builds, stairs and railings, sized and footed for the grade behind your house.
Porches
Covered, screened and three-season porches, built new or rebuilt where the posts and framing have gone. The roof tie-in is the part we get right.
Pergolas
Cedar, aluminum and louvered-roof pergolas, engineered for Jersey snow load and wind rather than assembled from a kit.
Sunrooms
Screened, three-season and four-season sunrooms — framed and finished like the rest of the house, not bolted on as a prefab kit.
What Remodeling Costs in Middlesex County
These are the ranges we work from across Middlesex County. Treat them as planning figures — on a house of this age, what is already behind the wall moves the number as much as the size of the project does. A 1960s split-level usually needs the electrical and the plumbing brought up along with the finishes, while a 1990s colonial in Monroe or South Brunswick is more often a cosmetic job at the low end of the range. Every project gets priced after we have seen the house.
| Project | Typical range | What moves it |
|---|---|---|
| Basement finishing | $45–$130 per sq ft | Ceiling height, moisture control, egress, and whether a bathroom or wet bar is included |
| Home additions | $250–$450+ per sq ft | Foundation work, the roof tie-in, building out versus up, and how much mechanical work it sets off |
| Porches | $40–$175 per sq ft | Covered, screened or three-season; whether it ties into the existing roofline |
| Sunrooms | $100 screened · $200 three-season · $260 four-season, per sq ft | Level of enclosure, foundation and whether it is heated and cooled |
| Pergolas | $38–$108 per sq ft | Material, span and post count, and whether the roof is fixed or louvered |
| Kitchen remodeling | $25–40k · $40–65k · $65–85k+ | Layout changes, cabinetry level, and whether plumbing or walls move |
| Bathroom remodeling | $18–25k · $25–40k · $40–55k+ | Size, whether the layout moves, and tile and fixture selections |
| Decks | Quoted per project | Height off grade, decking material, railing system and any built-ins |

Building Permits in Middlesex County, Town by Town
New Jersey works under one statewide building code, but the permit is issued and inspected by your own municipality — and the towns in Middlesex County do not all run it the same way.
A remodel that adds walls, circuits, plumbing or a roof is regulated work under the New Jersey Uniform Construction Code. The construction permit is reviewed under separate subcodes — building, electrical, plumbing and fire — each inspected on its own schedule, and rough work has to pass before it gets covered. Zoning is a separate review that happens alongside it, covering setbacks, lot coverage and height. We prepare the drawings, file the permit and meet the inspectors on every job we build, so this is the part you hand over rather than manage.
Here is how the offices differ across the Middlesex towns we work in most:
| Town | Construction office | Online permits | Worth knowing |
|---|---|---|---|
| Old Bridge | Building Permit Department | — | — |
| Edison | Division of Construction Code Enforcement, under Planning and Engineering | No — forms from the office or the NJ DCA | The zoning officer reviews first, before the construction subcodes. Two sets of plans plus a plot plan showing existing and proposed structures with distances to the lot lines. A contractor cannot prepare the drawings unless licensed as an architect or engineer. Inspections need 24 hours’ notice. |
| East Brunswick | Construction Inspection Division | — | The township spells out its deck rules: footings at least 3 feet below finished grade, ledgers bolted into a solid rim joist at least 2 inches thick, and guards required over 30 inches. Basement finishing, additions and alterations all need building subcode approval. |
| Piscataway | Building Division, under Community Development | No application portal shown — online payment and inspection booking only | One division handles building, electrical, plumbing and fire review and inspection. Inspections are booked through the division’s scheduling link rather than by phone. |
| Sayreville | Construction Department | Yes — FastTrackGov, with accounts to track application status | The borough tells residents to check with the office before starting any home improvement, and stresses that final inspections must be complete before final payment is made to a contractor. |
| North Brunswick | Building Regulations, a division of Community Development | Yes — SDL Portal | Permits are required for building or replacing a deck, finishing a basement or attic, and most renovations and additions. Ordinary maintenance of an uncovered porch or stoop does not need one, but substantive modification does. |
| South Brunswick | Code Enforcement Department | None shown — the page points to NJ DCA forms | Inspections are arranged by calling the department. Resale certificates are handled by Zoning rather than this office. |
| Monroe | Construction Office | None shown | Inspections are requested by email, stating the inspection type and permit number. Final building, electrical, plumbing and fire inspections must be complete before final payment to a contractor. A resale fire inspection goes through the local fire district, not this office. |
| Metuchen | Construction Code Enforcement Office | No — online payment is unavailable; forms from the office or NJ DCA | A project may need zoning approval as well. Inspections need 24 hours’ notice on a written request form, inspectors do not call ahead, and a missed appointment is rescheduled rather than revisited the same day. |
Checked against each township’s own website in September 2026. A dash means we could not confirm that detail from the town’s site — not that it does not exist. Municipal processes change, so treat this as a starting point and confirm with your town, or let us handle the filing. Not listed here is Woodbridge, which we also serve.
