Local Intelligence
What Long 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 Long Beach's ADU size limits. Long Beach's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Long 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 Long Beach can command approximately $2,000/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Community Development Department permit fees for this project type typically range from $3,000 to $20,000 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Community Development Department 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 Community Development Department ↗Construction Cost Context
Long Beach's garage conversion construction costs run $280–$490 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 Long Beach
If your lot sits anywhere near Ocean Boulevard, Belmont Shore, Naples, or the Peninsula, expect the Community Development Department to route your project through a Coastal Development Permit review on top of the standard plan check — that's a separate approval process that can tack on 6-12 extra weeks and sometimes gets kicked to the California Coastal Commission if it's appealed or falls outside the city's local coastal program authority. Long Beach also has a lot of older housing stock on Alquist-Priolo fault-adjacent soil, so plan checkers frequently kick back projects for additional soils reports tied to SDC D requirements, even for a simple detached ADU. And because short-term rentals aren't allowed here, don't bank on Airbnb income to pencil out the project financially when you're presenting numbers to a lender — the city actively checks rental registration against STR listing sites.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 6-week plan check and $400/sqft figure are Long Beach-flavored state estimates at best, so I'd get actual local contractor bids and call the Community Development Department directly before penciling in a budget or schedule — especially since you're in the coastal overlay, where the added CDP review has pushed real timelines for my clients out several extra months beyond what the base permit number suggests. — Charlotte Pemberton, Senior ADU Design Consultant"
Market Context
Long Beach has a median home value of $699,000. Comparable renovation projects in this market typically add 28.0% to resale value.
Neighborhoods in Long Beach with the strongest garage conversion and rental-unit potential include Bixby Knolls (Cal Heights), Los Altos, Belmont Heights, Belmont Shore, Naples Island. Tree-lined streets and larger lots with many single-family homes make Bixby Knolls ideal for detached ADUs.
Permit Process
Permit applications are reviewed by the Community Development Department, with a plan check timeline of approximately 6 weeks. Permit fees in Long Beach range from $3,000 to $20,000 depending on project scope. Design review: Yes - in historic districts and in the Coastal Zone (administrative Local Coastal Development Permit); otherwise No (ministerial building-permit review).
Long Beach falls within Seismic Design Category Seismic Design Category D (SDC D) for typical Risk Categories I–III; higher SDC (E or F) may apply for certain critical/essential facilities or specific site classes per ASCE 7/CBC, which affects structural requirements for converted garage walls and foundations.
Properties within Long Beach's Coastal Overlay Zone require a Coastal Development Permit in addition to standard building permits.

Common Questions
Long Beach Garage Conversion FAQs
Is a garage conversion allowed in Long Beach? +
Yes — garage conversions are permitted in Long Beach. California state law allows 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 Long Beach? +
Garage conversions in Long Beach typically range from $135,000 to $297,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Our drawing package starts at $997 — a fraction of what a local architect would charge for the same permit-ready set.
What drawings are required to permit a garage conversion in Long Beach? +
Long 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 (Title 24 in California). 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 Long Beach? +
Plan check in Long Beach typically takes approximately 6 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 Long 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 Long 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 Long Beach? +
Our permit-ready garage conversion drawing packages for Long Beach start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for CA code compliance and formatted for Long Beach's building department. Turnaround is 10 business days with a 14-day money-back guarantee.
Will converting my garage increase my home's value in Long Beach? +
A permitted garage conversion in Long Beach adds rentable square footage to a home currently valued around $699,000. 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.
