Local Intelligence
What Manhattan Beach Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Manhattan Beach's ADU size limits. Manhattan Beach's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Manhattan Beach does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
A fully permitted, code-compliant garage conversion in Manhattan Beach can command approximately $2,278/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Garage conversion drawings submitted to Building and Safety must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural plans are typically required for converted garages that are detached or require seismic upgrades.
Visit Building and Safety ↗Construction Cost Context
Manhattan Beach's garage conversion construction costs run $250–$540 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 Manhattan Beach
Because most Manhattan Beach lots sit within the Coastal Zone, your ADU plans need a Coastal Development Permit on top of the standard Building and Safety review — and if your project isn't exempt (say it's visible from a public viewing corridor or near the Strand), that can tack on another 2-4 months and a separate staff-level review before you even get to plan check. Add in the city's D0 seismic zone requirements, which often mean stamped calculations for soil bearing and shear walls that a generic ADU plan set won't already include, and many homeowners get bounced back for corrections on their first submittal. Also don't assume you can offset costs with a short-term rental — Manhattan Beach explicitly bans STRs in ADUs, so the numbers only work as long-term housing or family use.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 12-week permit timeline is a state-level estimate and doesn't account for Manhattan Beach's Coastal Development Permit process, which routinely adds several months once you're in the Coastal Zone — I've seen straightforward ADUs stretch past 6 months once CDP review and any Coastal Commission appeal window come into play. I'd also treat the $/sqft cost figure as a starting point only; get quotes from contractors who've actually pulled ADU permits here recently, since coastal construction and soil conditions can push real numbers well above generic averages."
Market Context
Manhattan Beach has a median home value of $2,400,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Manhattan Beach with the strongest garage conversion and rental-unit potential include Mira Costa Area (East Manhattan Beach), Liberty Village, Tree Section, Poets Section, Manhattan Heights. Large 7,500+ sq ft lots, almost entirely single-family homes, and walking distance to Mira Costa High School drive strong year-round rental demand for both staff and student families.
Permit Process

Manhattan Beach falls within Seismic Design Category D0, which affects structural requirements for converted garage walls and foundations.
Properties within Manhattan Beach's Coastal Overlay Zone require a Coastal Development Permit in addition to standard building permits.

Common Questions
Manhattan Beach Garage Conversion FAQs
Is a garage conversion allowed in Manhattan Beach? +
Yes — garage conversions are permitted in Manhattan Beach. California state law allow homeowners to convert an attached or detached garage into habitable living space or an ADU. A building permit and permit-ready drawings are required before work begins.
How much does a garage conversion cost in Manhattan Beach? +
Garage conversions in Manhattan Beach typically range from $120,000 to $264,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Contact us to discuss drawing package options for your project.
What drawings are required to permit a garage conversion in Manhattan Beach? +
Manhattan Beach's building department requires: a site plan showing the converted garage's location on the lot, floor plans with dimensions and room labels, all four exterior elevations, an electrical plan, and energy compliance documentation (California Title 24). Our Starter package covers all of these. If the garage is detached or the structure requires seismic upgrades, stamped structural drawings are also required — included in our Premium package.
How long does the permit process take for a garage conversion in Manhattan Beach? +
Plan check in Manhattan Beach typically takes approximately 12 weeks. Having complete, code-compliant drawings dramatically reduces correction cycles — which each add 3–6 weeks. Our drawings are designed to pass on the first submittal.
Can I convert my garage into a rental unit in Manhattan Beach? +
Yes — a permitted garage conversion can function as a standalone rental unit (ADU or JADU depending on size). In California, converted garages under 500 sq ft qualify as Junior ADUs (JADUs), while larger conversions qualify as full ADUs. Both can be rented long-term. Short-term rental rules vary by city — confirm with Manhattan Beach's planning department.
Do I need to replace the garage door opening when converting? +
Yes. The garage door must be replaced with an insulated wall with a standard entry door and at least one egress window (minimum 5.7 sq ft clear opening). This is captured in our elevation drawings and flagged in the electrical plan. The new wall must also meet CA energy code requirements, which we handle in the Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Manhattan Beach? +
Our permit-ready garage conversion drawing packages for Manhattan Beach include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for CA code compliance and formatted for Manhattan Beach's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in Manhattan Beach? +
A permitted garage conversion in Manhattan Beach adds rentable square footage to a home currently valued around $2,400,000. Converted spaces typically appraise as habitable square footage, increasing the home's value. As an ADU or JADU, the rental income stream is also capitalized into the appraised value — typically at a 5–6% cap rate.
