Story
Permit drawing sets for single family home remodels
Every residential remodel that involves structural changes, electrical upgrades, plumbing modifications, or changes to the building envelope requires a permit set.
Story
Lateral extensions and rear yard expansions for existing homes
A home extension grows your existing footprint outward expanding a kitchen, adding a family room, or extending a master bedroom toward the rear or side of your lot.
Story
Home addition drawings for single family dwellings
A single family home addition adds new square footage to your existing structure — a new bedroom, a second floor, a master suite over the garage, or a rear addition expanding multiple rooms at once. We produce complete addition drawing sets covering all required sheets existing and proposed floor plans, all exterior elevations, building sections, roof framing plan, foundation plan, structural notes.
What Counts as a Single Family Dwelling in Los Angeles?
A single family dwelling (SFD) is a standalone residential structure designed and occupied by one household. In Los Angeles, LADBS classifies single family dwellings separately from multi-family properties — and each classification carries different permit requirements, zoning rules, and documentation standards.
kitchen remodeling plans
Kitchen remodels involving structural walls, new plumbing, or electrical upgrades require a permit set before work begins. We document existing kitchen conditions and produce proposed drawings showing updated layouts, cabinet configurations, island placement, and all required LADBS notes.
Bathroom Remodeling Plans
Relocating fixtures, expanding square footage, or modifying plumbing in a bathroom requires permit drawings. We produce bathroom plan sets documenting existing and proposed conditions — fixture layouts, plumbing rough-ins, ventilation, and waterproofing notes.
house extension design plans
Expanding your home outward requires a complete extension drawing set. We produce existing and proposed floor plans, updated exterior elevations, structural notes, and a revised site plan showing new setback dimensions — everything LADBS needs for extension permit approval.
Garage Extension Plans
Adding a second bay, expanding storage, or building above an existing garage requires permit drawings showing current and proposed conditions. We deliver garage extension plan sets including floor plan, elevations, structural notes, and updated site plan — fast turnaround, LADBS-ready.
Whole-Home Remodel Plans
A remodel touching multiple rooms, structural walls, or building systems requires a coordinated full-property drawing set. We document existing conditions throughout and produce complete proposed drawings — giving your contractor precise instructions and LADBS a clean, code-compliant submission.

As Built Floor Plan for Single Family Homes
An as built floor plan shows the real layout of your home today: room sizes, walls, doors, windows and stairs, measured on site. Single family homeowners, architects and contractors use it as the starting point for remodels, additions, ADUs and permit submittals. We deliver the floor plan in AutoCAD and Revit, ready to review.
