- Bedroom layout with storage and closet planning

Serving Bergen County homeowners across Englewood, Tenafly, Fort Lee, Ridgewood, Paramus, Teaneck, Hackensack, Closter, Fair Lawn, and Bergenfield — plus every town in between.
Requirements vary by municipality. Bergen Restoration helps plan the renovation scope and coordinate permit, egress, inspection, and licensed-trade considerations where applicable. We do not guarantee legal apartment, rental, or ADU approval.
Guest Suite & In-Law Space Guides
Decisions that determine whether the project lasts and feels right.
Living Layout Planning
- Bedroom, bath, sitting area, and optional kitchenette are arranged for privacy from the main house without dead-end halls.
- Door swings and furniture clearances are checked for mobility and guest luggage reality.
- Shared vs separate entry and bath access are decided early — they drive plumbing and fire-separation scope.
- A sitting area — even six feet of it — separates a guest suite from a guest room; long stays need somewhere to be besides the bed.
- Luggage landing and closet space size to visit length: hooks and a rack serve weekends; long stays want real storage.

Private Bath Integration
- Locating the new bath above or beside existing plumbing runs is the single biggest cost lever in suite conversions.
- A three-fixture bath (shower, toilet, vanity) fits in roughly 5×8 feet — most suite plans can find it without stealing the bedroom.
- New fixtures need proper drain venting; that scope is confirmed at design so walls open once, not twice.
- A pocket door recovers the swing space small suite baths never have.
- Ventilation runs ducted outside like any bath — suite baths tucked into interior corners can't cheat this.

Optional Kitchenette
- A sink, undercounter fridge, and microwave drawer cover long-stay independence without triggering full-kitchen requirements.
- Cabinet runs match the main-house finish level so the kitchenette reads as intentional millwork, not an afterthought.
- Electrical for the kitchenette lands on its own circuits, roughed in while walls are open.
- A counter-height eating ledge makes the kitchenette a breakfast spot without claiming dining-room square footage.
- Under-cabinet lighting and one good task light make a small kitchenette feel finished, not improvised.

Privacy & Sound Isolation
- Insulated interior walls and a solid-core door cut normal household noise to a murmur — the difference guests actually notice.
- A dedicated mini-split or zoned damper gives the suite its own temperature without touching the main system’s balance.
- Door placement off a hall rather than a shared living space adds privacy no wall assembly can.
- Separate thermostat control ends the guest-comfort negotiation — their room, their temperature.
- TV and Wi-Fi provisioning (wired drop or strong AP coverage) is hospitality infrastructure now.

Accessibility & Mobility
- Doorways at 36 inches and zero thresholds cost little during construction and everything to retrofit.
- A curbless shower with blocking for future grab bars makes the suite age-capable without looking clinical.
- Lever handles, rocker switches, and reachable outlet heights complete the mobility package invisibly.
- First-floor suites age with the household — today's guest room is a future main-level bedroom when stairs get long.
- Blocking, widths, and curbless rough-ins cost almost nothing now and everything later.

Cost & Timeline Guide
- Within existing footprint $35k–$85k; kitchenette and bath addition $80k–$160k+.
- Second means of egress, fire separation, and plumbing runs for a bath are the code-driven adders.
- Permits track bedroom, bath, and any kitchen plumbing; 6–14 weeks depending on whether walls move.
- Bath and kitchenette plumbing are the budget's swing items — location relative to existing lines moves the number most.
- Suites within the existing footprint run weeks; bump-out versions run months — the footprint decision is the schedule decision.

Build
Crew executes egress cut, framing, plumbing, electrical, HVAC, drywall, tile, cabinetry, and finish work.
Final walkthrough
Inspection coordination, walkthrough, and punch-list closeout.
Frequently Asked Questions
For 2026 in Bergen County, studio guest bedroom + bath runs $35,000–$75,000. Full in-law apartment with kitchenette, laundry, and dedicated HVAC runs $80,000–$180,000+ depending on egress scope and finishes. Pricing and timelines are planning ranges.
Yes. Bergen County municipalities enforce NJ Residential Code requirements for sleeping rooms below grade: a code-sized egress window plus window well meeting minimum dimensions. We cut and install the opening, well, and cover as part of the scope.
For projects that require permits, we coordinate permit paperwork, trade documentation, and inspection scheduling with your town and licensed professionals where required. Egress cuts, new bathrooms, and HVAC additions trigger permits in every NJ municipality.
Studio guest suite 6–10 weeks. Full in-law apartment with egress, kitchenette, and HVAC 10–18 weeks depending on finishes and inspection schedules.
Yes. Bergen Restoration is a registered New Jersey Home Improvement Contractor (NJHIC# 13VH08865500) with commercial general liability and workers' compensation coverage. Documentation is available on request, and homeowners should verify credentials before hiring any contractor.
A full bath, real storage, and enough independence that a two-week stay doesn't run through the family's morning routine. The bath is the project's center of gravity.
A sink, fridge, and counter run works in most towns; a full second kitchen can push into two-family territory in some zoning. We flag the line for your address before design locks.
Insulated walls and ceiling, solid-core doors, and layout that puts the suite's quiet side against quiet neighbors — privacy in both directions is the design brief.
Curbless shower, blocking for grab bars, wider doorways, lever handles — nearly free during construction, expensive after. Aging-in-place logic applies even for young guests.
Where grade and layout allow, an exterior door transforms the suite's independence. It also raises zoning questions in some towns — checked early, not assumed.
A stacked washer-dryer closet is the amenity long-stay guests and in-laws actually use most. Plumbing it during the build costs a fraction of adding it later.
