Permitting & Design Services Conditions in Santa Monica
Salt air is the other factor. Openings, fasteners, flashing and exterior metal all corrode faster within a mile of the water, so we specify corrosion-resistant materials rather than whatever is cheapest on the shelf. Lots are narrow and street parking is limited, which means staging materials day by day instead of filling a driveway.
- 1920s to 1940s bungalows with galvanized pipe and original wiring
- Local energy and green building amendments above state minimums
- Corrosion-resistant windows, fasteners and flashing for coastal exposure
- Narrow lots with limited staging and parking for crews
- Foundation bolting and cripple wall bracing on most pre-war houses
Legalizing Unpermitted Work
If you bought a house with an unpermitted garage conversion, addition or second unit, you can often bring it into compliance instead of tearing it out. We document the existing conditions, draw what's there, identify what has to change, and take it through the city.
- As-built documentation of existing conditions
- Code gap analysis and correction scope
- Permit submittal for existing unpermitted work
- Inspection coordination and final sign-off
Why a Builder Should Draw It
Plans drawn without a builder in the room tend to be beautiful and unbuildable at the budget. Because we build what we design, we price as we draw, flag structural and utility costs early, and give you a set the city approves and a crew can actually follow.
- Budget check at every design milestone
- Constructability review before submittal
- Plan check corrections handled by us
- The same team builds it if you go ahead with us
FREQUENTLY ASKED QUESTIONS
Do you do permitting & design services in Santa Monica?
Yes. Santa Monica is part of our regular service area. We'll come out for a free on-site consultation, walk the property, and tell you what's realistic before you spend anything on design.
What does permitting cost in Santa Monica?
$3,500 – $40,000+ depending on scope and engineering. Site conditions in Santa Monica and your material selections move the number, which is why we price after walking the property rather than over the phone.
Who issues the permit in Santa Monica?
Permits for this work go through Santa Monica Building & Safety. We handle the submittal, plan check corrections and inspections as part of the project.
How much do architectural plans and permits cost in Los Angeles?
Plans for a kitchen or bathroom remodel typically run $3,500 to $8,000. Additions and ADUs with structural engineering usually land between $12,000 and $25,000, and custom homes or hillside projects run $40,000 and up, plus city fees.
How long does LADBS plan check take?
Simple over-the-counter permits can be same day. Standard plan check for additions and ADUs usually takes 4 to 16 weeks including one or two correction cycles, and hillside or discretionary projects take longer.
Can you legalize an unpermitted addition or garage conversion?
In most cases, yes. We document what exists, identify what has to be corrected to meet current code, and take it through permitting and inspection so it shows up as legal square footage.
Do I have to build with you if you draw my plans?
No. The plans are yours. Most clients do continue with us because the pricing is already built into the design, but you're free to bid the drawings out.
