What Los Angeles Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Los Angeles — Los Angeles Department of Building and Safety will not accept a permit application without them. Los Angeles's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Los Angeles does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Los Angeles who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,100/month.
Permit Process & Fees
Los Angeles Department of Building and Safety permit fees for this project type typically range from $3,500 to $12,000 depending on project valuation and scope. Plan check runs approximately 10 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Los Angeles Department of Building and Safety as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Los Angeles Department of Building and Safety ↗Construction Cost Context
Los Angeles's adu / renovation construction costs run $240–$490 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Los Angeles
If your lot sits in the Coastal Zone (common in Venice, Pacific Palisades, or San Pedro), LADBS won't be the only agency you deal with — you'll also need a Coastal Development Permit, which can tack on 3-6 months and often requires public notice to neighbors before it's approved. LADBS plan checkers in the Van Nuys and West LA offices are also known for flagging ADU plans over soft-story or non-ductile concrete parcels for extra seismic review, since much of LA sits in Seismic Design Category D, so don't be surprised if your structural engineer gets a second round of corrections. And since short-term rentals aren't allowed on ADUs here, LA's Housing Department will require you to sign a covenant restricting the unit to rentals of 30+ days before they'll sign off on your Certificate of Occupancy.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 10-week timeline and $300/sqft figure are Los Angeles state-level estimates that rarely hold up locally — I'd call LADBS directly and get a couple of contractor quotes before you budget around them. And since this property sits in the Coastal overlay, don't underestimate the Coastal Development Permit process on top of standard plan check; I've seen that step alone add several months when the California Coastal Commission gets involved."
Market Context
Los Angeles has a median home value of $790,000. Comparable renovation projects in this market typically add 30.0% to resale value.
Neighborhoods in Los Angeles with the strongest renovation and resale value potential include Silver Lake, Los Feliz, Echo Park, Atwater Village, Highland Park. High concentration of single-family lots near job centers and strong rental demand makes ADUs financially attractive.
Permit Process
Permit applications are reviewed by the Los Angeles Department of Building and Safety, with a plan check timeline of approximately 10 weeks. Permit fees in Los Angeles range from $3,500 to $12,000 depending on project scope. Design review: Yes - in HPOZ historic districts and in other overlay/discretionary areas (e.g., Coastal Zone/CDP); otherwise ministerial/no citywide design-review.
Los Angeles falls within Seismic Design Category Seismic Design Category D (site-dependent; some sites in Los Angeles may map to SDC E) per ASCE 7, which affects structural requirements for any new addition tying into the existing structure.
Properties within Los Angeles's Coastal Overlay Zone require a Coastal Development Permit in addition to standard building permits.

Common Questions
Los Angeles Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Los Angeles? +
You need accurate floor plans for: permit applications (required by Los Angeles's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Los Angeles? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Los Angeles's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Los Angeles? +
Our floor plan drafting packages for Los Angeles start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Los Angeles home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Los Angeles neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Los Angeles building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Los Angeles? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Los Angeles. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Los Angeles? +
In Los Angeles, where median home values are around $790,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Los Angeles? +
Yes — Los Angeles's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Los Angeles? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Los Angeles homes built before the 1990s.
