Common Uses in West Covina
Local Intelligence
What West Covina Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in West Covina — Building Division will not accept a permit application without them. West Covina's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
West Covina 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 West Covina who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,912/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $3,500 to $12,000 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building Division 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 Building Division ↗Construction Cost Context
West Covina's adu / renovation construction costs run $245–$420 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 West Covina
Many West Covina lots sit on older sewer laterals shared with the main house, and the Building Division will often require a sewer camera inspection before signing off — if that clay pipe from the 1950s is cracked or root-infested, you're looking at a $8,000-$15,000 replacement that nobody budgeted for. Because the city sits in a soil transition zone (Site Class D2 under CRC), some lots near the foothills get flagged for supplemental soils reports even outside the hillside zones, which can add 3-4 weeks if your engineer didn't anticipate it. Also worth knowing: West Covina's plan check staff is small, so resubmittals after corrections often sit in queue for another 2-3 weeks rather than getting expedited, which catches people off guard when they assumed "revise and resubmit" meant a quick turnaround.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with West Covina plan checks, that 8-week timeline and $350/sqft figure are state-level estimates rather than verified local numbers, so I'd urge you to get actual bids from contractors who've pulled ADU permits here recently and call the Building Division to confirm current turnaround times before penciling in a schedule. With 35% HOA prevalence in the area, don't overlook that an HOA architectural review can add its own delay on top of whatever the city quotes you."
Market Context
West Covina has a median home value of $660,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in West Covina with the strongest renovation and resale value potential include South Hills, Woodside, West Puente Valley, Galaxie, South San Jose Hills. Large single-family lots and high home values make South Hills well-suited for detached ADUs and high rental income potential.
Permit Process
Permit applications are reviewed by the Building Division, with a plan check timeline of approximately 8 weeks. Permit fees in West Covina range from $3,500 to $12,000 depending on project scope. Design review: Other: Generally No for ADUs (ministerial Second Unit Review), but Planning Commission Subcommittee for Design Review must review certain exterior alterations to single-family residences (e.g., new front-facing construction, front elevation changes, additions visible from a public right-of-way), so some ADU projects that alter visible elevations may require subcommittee review..
West Covina falls within Seismic Design Category E (may be E or F depending on site-specific S_s/S_1 and site class); Site Class D (CBC) / D2 (CRC) typical, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
West Covina Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in West Covina? +
You need accurate floor plans for: permit applications (required by West Covina'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 West Covina? +
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. West Covina'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 West Covina? +
Our floor plan drafting packages for West Covina 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 West Covina 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 West Covina 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 West Covina 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 West Covina? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in West Covina. 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 West Covina? +
In West Covina, where median home values are around $660,000, 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 West Covina? +
Yes — West Covina'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 West Covina? +
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 West Covina homes built before the 1990s.
