Local Intelligence
What Cerritos Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Cerritos — Department of Community Development will not accept a permit application without them. Cerritos's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Cerritos 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 Cerritos who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,762/month.
Permit Process & Fees
Floor plans submitted to Department of Community Development 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 Department of Community Development ↗Construction Cost Context
Cerritos's adu / renovation construction costs run $240–$400 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 Cerritos
Cerritos is almost entirely built out with mid-century tract homes on planned-unit lots, so many properties still have the original 1960s-era CC&Rs tied to the Cerritos Homeowners Association overlay in certain tracts — even though the city itself doesn't enforce these, your ADU plans can get flagged in escrow or by a neighbor if setbacks or roof pitch don't match the original PUD design guidelines. Because most homes here run on smaller lot depths common to the Los Cerritos and Faculty tract areas, fitting a detached ADU while keeping the required rear yard setback often forces a redesign around the existing block wall, which many homeowners don't discover until the city's plan checker kicks back the first submittal. Given the Zone D seismic rating, expect the structural engineer to add shear wall or moment frame details for a detached unit, which is a common reason first-round plan checks get rejected here rather than approved outright.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, the missing timeline and cost figures here are essentially placeholders rather than real Cerritos data, so I'd treat any state-level average per-square-foot cost or plan check estimate you find elsewhere as a starting point only — call Cerritos Community Development directly and get at least two local contractor quotes before budgeting. With 35% of the city under HOA governance, don't be surprised if your true bottleneck isn't the city's plan check at all, but a slower HOA architectural review process layered on top of it."
Market Context
Cerritos has a median home value of $950,000. Comparable renovation projects in this market typically add 30% to resale value.
Neighborhoods in Cerritos with the strongest renovation and resale value potential include Cerritos North, Cerritos Northeast, The Boardwalk / Casa Grande, Cerritos Hills, Cerritos Town Center. Family-friendly suburban area with spacious lots and residential zoning that widely permits detached ADUs near top-rated schools.
Permit Process
Permit applications are reviewed by the Department of Community Development.
Cerritos falls within Seismic Design Category D, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Cerritos Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Cerritos? +
You need accurate floor plans for: permit applications (required by Cerritos'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 Cerritos? +
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. Cerritos'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 Cerritos? +
Our floor plan drafting packages for Cerritos cover 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 comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Cerritos 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 Cerritos 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 Cerritos 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 Cerritos? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Cerritos. 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 Cerritos? +
In Cerritos, where median home values are around $950,000, 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 Cerritos? +
Yes — Cerritos'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 Cerritos? +
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 Cerritos homes built before the 1990s.
