Additions & Remodels in Marina del Rey, Los Angeles County
Kitchen, bath, second-storey and whole-house work, designed and permitted properly so the finished result appraises and sells as legal square footage. In Marina del Rey that work is reviewed by LA County Public Works Building and Safety, with County Regional Planning, with LA County Fire involved where access, alarms or suppression apply. This is County territory, not City of LA. Using the wrong department's assumptions is the single most common Marina mistake.
What home addition and remodel design involves in Marina del Rey
Marina del Rey sits in Westside, inside Los Angeles County, and plan review runs through LA County Public Works Building and Safety, with County Regional Planning. The housing stock matters here: condominium stock plus a small pocket of single-family on the Strand. That existing condition, more than any design preference, sets what is straightforward and what is expensive.
Before we draw anything we run a feasibility review against your specific address. For home addition and remodel design that means testing existing conditions survey and as-built drawings, addition and remodel design, structural design for openings, second storeys and foundations, and confirming which of the local overlays apply to your parcel. Getting a no in week one costs you a small fee. Getting a no in month five costs you a design.
Once feasibility comes back workable, we produce a permit set that anticipates how this particular department reads the code, submit it, and manage the corrections ourselves. Typical experience in Marina del Rey is roughly 10 to 18 weeks through the County, plus coastal where applicable. On fees, County fee schedules differ noticeably from City of LA; assume different numbers, not similar ones.
What drives the cost of home addition and remodel design here
Additions generally run roughly $350 to $600 per square foot depending on complexity, with kitchens and baths priced by scope rather than area.
Those ranges are honest averages, not quotes. The variables below are the ones that actually move the number on a Marina del Rey project, and they are the first four things we investigate.
Foundation
Adding load to a 1920s foundation usually means underpinning or replacement in the affected area, and that shows up as a real line item.
Roof and structure
A second storey is a structural project with a finish layer, not a finish project. Load path is the first drawing, not the last.
Systems age
Knob and tube wiring, galvanised supply and cast iron waste all get triggered by permitted work. Better to plan for them.
Occupied construction
Living in the house during the work is possible, and it lengthens the schedule. We price both scenarios so you can choose.
Timeline and approvals in Marina del Rey
Design and permitting usually takes 3 to 5 months, and construction of a meaningful addition runs 5 to 10 months.
Layered onto that, Marina del Rey review typically takes roughly 10 to 18 weeks through the County, plus coastal where applicable. Where one of the local overlays applies, add its process to the front of the schedule rather than assuming it runs in parallel.
We work across Marina del Rey ZIP codes 90292 and 90293, and the neighbourhoods most represented in our Marina del Rey work are Silver Strand, Marina Peninsula edge, Villa Marina, Admiralty Way corridor. Where your parcel sits inside the city changes which overlays and which reviewers you meet.
We give you a written schedule with the approval milestones named, so you can see which dates we control and which belong to an agency. Nobody can compress a hearing calendar. Everybody can submit a complete package the first time, and that is where the recoverable weeks are.

Additions & Remodels in Marina del Rey: common questions
Who reviews home addition and remodel design in Marina del Rey?
LA County Public Works Building and Safety, with County Regional Planning, with LA County Fire reviewing access, alarm and suppression scope where it applies. This is County territory, not City of LA. Using the wrong department's assumptions is the single most common Marina mistake.
How long does home addition and remodel design take to permit in Marina del Rey?
Expect roughly 10 to 18 weeks through the County, plus coastal where applicable. Design and permitting usually takes 3 to 5 months, and construction of a meaningful addition runs 5 to 10 months. We name the agency-controlled milestones separately in your schedule so you can see what is ours and what is theirs.
What does home addition and remodel design cost in Marina del Rey?
Additions generally run roughly $350 to $600 per square foot depending on complexity, with kitchens and baths priced by scope rather than area. Locally, County fee schedules differ noticeably from City of LA; assume different numbers, not similar ones. We price the three biggest variables at feasibility so the first number you see is close to the last one.
Which local rules commonly affect projects in Marina del Rey?
The ones that come up most are: County coastal jurisdiction and Local Coastal Program; Marina lease parcels with County Beaches and Harbors involvement; Flood zone construction standards near the channel. We confirm which apply to your parcel before design rather than discovering one at plan check.
Which Marina del Rey ZIP codes do you cover?
We take home addition and remodel design work across 90292 and 90293, plus surrounding unincorporated pockets. If your ZIP is not listed, send the address anyway and we will tell you plainly whether we are the right team for it.
Can I add a second storey to my house?
Often yes, subject to height limits, setbacks and whether the existing foundation and framing can carry the load. The foundation answer is the expensive one, so we investigate it during feasibility rather than after design.
Will unpermitted existing work cause a problem?
It can. Once you pull a permit, the department sees the whole property. Unpermitted space usually has to be legalised or removed. We would rather find it in week one and plan for it than have an inspector find it in month six.
Do I need a designer and a contractor separately?
Not with us. We handle design, permitting and construction under one agreement, so there is nobody to blame when a drawing and a field condition disagree.
