Project Types

Addition Projects We Document

Whether you're planning a kitchen addition, family room expansion, master suite addition, in-law suite, second story addition, or add-a-level, your project requires permit documentation before construction can begin. NJ Permit Plans prepares what's needed and guides you through municipal review — so you can move from plans to permits to building.

Rear Additions

Single-story expansions to the rear of an existing home — kitchens, family rooms, mudrooms, and primary suite additions.

  • Foundation plan and details
  • Floor plan with dimensions
  • Exterior elevations
  • Roof framing and details

Add-A-Levels

Second-story additions over an existing footprint. One of the most complex addition types — requires careful coordination with existing structure.

  • Existing and proposed floor plans
  • All four elevations
  • Structural coordination drawings
  • Stair and egress documentation

Garage Additions

Attached or detached garage additions including conversions and expansions. Setback and fire separation requirements documented.

  • Site plan with setback dimensions

Primary Bedroom Suites

Expand your home with a first-floor or second-floor primary suite including bedroom, bathroom, closets, and supporting living space.

  • Floor plan with bath and closet layout
  • Exterior elevations
  • Foundation and structural details
  • Egress and life safety documentation

Family Room Expansions

Ground-floor additions that expand existing living areas — often combined with kitchen reconfigurations or open-plan conversions.

  • Existing and proposed floor plans
  • Structural beam and header details
  • Exterior elevations
  • Energy code documentation

Covered Porches & Sunrooms

Covered additions that extend livable or semi-livable space. Permit requirements vary by enclosure type and conditioned status.

Process

What to Expect

We work with municipalities throughout New Jersey and understand the documentation requirements commonly requested for residential permit applications. Here's how the process works.

1

Initial Project Review

We review your project — scope, site, zoning considerations, and any constraints that could affect the permit process. No surprises later.

2

Permit Drawings

We prepare the architectural drawings and code documentation required for your municipality. Floor plans, site plan, elevations, and any required details — ready for submission.

3

Municipal Coordination

We coordinate with your construction office as needed during review. If questions come up, we respond — so the process keeps moving.

4

Permit Approval

Once your permit is approved, your contractor can pull permits and begin construction. That's what this is all for.

Before You Build

Key Permit Considerations for Additions

Zoning & Setbacks

Every addition must comply with local zoning setback requirements. We identify setback constraints early and document compliance on the site plan.

Structural Engineering

Structural requirements vary by project. Where engineering is required, NJ Permit Plans coordinates the necessary structural documentation as part of your permit package.

NJ Energy Code

All addition projects must comply with the current NJ Energy Subcode. We prepare the required energy documentation as part of the permit package.
