Pricing & Cost FAQs
Most detached ADUs in Long Beach run between $180,000 and $320,000, while garage conversions typically land between $90,000 and $160,000 depending on the condition of the existing structure. Your final number moves based on square footage, foundation work, utility tie-ins, and finish level. Long Beach lot shapes drive cost more than most people expect: narrow lots in Belmont Heights or Alamitos Beach often need custom plans, which adds design time. We give every homeowner a written line-item price before any work starts, so you know exactly what you're paying for. Call (562) 362-3885 for a free estimate on your specific property.
A garage conversion is almost always the least expensive path, generally $90,000 to $160,000 in Long Beach because walls, roof, and foundation already exist. You save on the biggest structural costs and put money toward electrical, plumbing, drywall, and finishes instead. Attached ADUs carved out of existing square footage cost less than new detached construction, but they reduce your main house. Junior ADUs under 500 square feet are the lowest-cost category overall, often legalized as part of the primary residence with a small kitchenette. For an exact number on your specific garage or attached space, call (562) 362-3885.
A new detached ADU in Long Beach typically ranges from $220,000 to $350,000 for a one-bedroom unit between 400 and 600 square feet. Two-bedroom detached units with kitchens and laundry run higher, often $280,000 to $420,000. Long Beach soil and setback requirements affect foundation costs, and homes in older neighborhoods like Rose Park or Wrigley may need upgraded electrical service from the alley. Every project we price includes a written breakdown of hard costs, permits, and finishes before you commit. Call (562) 362-3885 and we'll put your number in writing.
ADUs in Long Beach typically add 20 to 30 percent to a property's appraised value, and a one-bedroom unit rents for roughly $1,800 to $2,400 per month depending on the neighborhood. Proximity to Cal State Long Beach, the Blue Line, and downtown employers keeps tenant demand strong year-round. Many homeowners use the rental income to offset their mortgage or house family members close by. The exact return depends on your lot, the unit's size, and how it's finished. We can walk you through realistic rent and resale numbers for your block. Call (562) 362-3885 for a free consult.
Not from us. The price we put in writing is the price you pay unless you change the scope. The trade's honest answer is that surprises do exist under the surface: a garage slab without proper footings, a sewer line that needs replacing, or a main panel that can't handle the new load. In older Long Beach homes near Retro Row or Cambodia Town, we regularly budget for these upgrades from day one so they don't ambush you mid-project. We don't take change orders without your written approval. Call (562) 362-3885 to see a real line-item estimate.
We don't lend money directly, but we can point you toward financing options that work for ADU construction, including renovation loans, home equity lines, and cash-out refinances. Many Long Beach homeowners use a HELOC because the ADU's rental income can cover the payments. The state of California also offers grants for lower-income homeowners building ADUs, though availability changes year to year. We're happy to write the detailed cost breakdown your lender will ask for. Call (562) 362-3885 and we'll talk through what works for your situation.
Service & Process FAQs
It starts with a site visit and a written price, then moves through design, city permitting, construction, and final inspection. In Long Beach, the Development Services Department reviews ADU permits under streamlined state law, meaning most applications get a decision within 60 days of submittal. The build itself usually takes 6 to 10 months for a detached unit and 4 to 7 months for a garage conversion. We track every stage and send photo updates so you always know where the project stands. Call (562) 362-3885 to walk through the timeline for your specific property.
A garage conversion in Long Beach typically takes 4 to 7 months from demo to final inspection, while a ground-up detached ADU runs 6 to 10 months. Permitting adds time up front: Long Beach's Development Services Department usually issues ADU permit decisions within 60 days of submittal under state streamlining law. Site conditions matter too. A detached build on a flat lot in Lakewood moves faster than one on a sloped Bixby Knolls hillside that needs retaining walls. We give you a written schedule with milestones from the start. Call (562) 362-3885 for a realistic timeline on your lot.
Yes. We handle all site plans, architectural drawings, energy calcs, and permit submittals with the City of Long Beach. The city's ADU ordinance is generally permissive, but individual lots have quirks: utility easements along the alley in Carroll Park, flood zone requirements near the Los Cerritos Channel, or historic district reviews in Bluff Park. We know what each neighborhood triggers before we start drawing, which keeps your timeline honest. We pull every permit under our name and coordinate every inspection. Call (562) 362-3885 and ask us what your lot will require.
Almost always, yes. Long Beach follows California state ADU law, which allows garage conversions by right in single-family zones, even if the garage was originally built attached or detached. You lose the enclosed parking space, but the city waives any parking replacement requirement for ADUs under these state rules, including conversions within a half-mile of transit. Structurally, most garages need slab reinforcement, new framing for insulation, and electrical upgrades to become legal living space. We've converted garages all over the city. Call (562) 362-3885 and we'll look at yours.
Yes. While our home base is Long Beach, we build ADUs across the surrounding communities including Downey, Buena Park, Cerritos, La Mirada, Bell, Seal Beach, Artesia, La Palma, Signal Hill, West Rancho Dominguez, and Lakewood. Each city has its own planning department, its own fees, and its own review habits. Our local team knows the inspectors and the code interpretations in each one. If you're in one of those areas, call (562) 362-3885 and we'll tell you exactly what your city requires before you spend a dime.
Yes, and Long Beach has thousands of small lots. State law requires cities to approve ADUs up to 800 square feet on nearly any single-family lot, regardless of the underlying zoning's minimum lot size. On a tight lot in Alamitos Beach or Belmont Shore, we typically design a compact one-bedroom or studio footprint that preserves yard space and matches the main house's scale. Sometimes the smartest move is a two-story ADU with living space above and a garage or storage below, which maximizes a small footprint. Call (562) 362-3885 to see what fits on your lot.
A JADU, or junior accessory dwelling unit, is a smaller unit of 500 square feet or less created from existing space inside the main house, like a converted bedroom or den. It needs its own entrance and an efficiency kitchen but may share a bathroom with the main house. An ADU is a fully independent unit, either attached or detached, with its own kitchen and bathroom. JADUs are the cheapest path in Long Beach and often add rental income without a big construction footprint. We can help you decide which fits your property and your budget. Call (562) 362-3885.
Yes, but only on the added value, not your entire home's value. Long Beach and Los Angeles County reassess only the new construction, so if you build a $250,000 ADU on a home already taxed at its base value, property taxes increase based on the ADU's assessed value at current rates. That's the honest answer: your tax bill will go up, and the increase is typically balanced by rental income or increased resale value. We can refer you to a tax advisor for your specific circumstances. Call (562) 362-3885 with other ADU cost questions.
Brands & Parts FAQs
We build our own units from the foundation up, so we're not locked into any single prefab factory. Where the design calls for it, we've worked with manufacturers including Plant Prefab, Tuff Shed, Abodu, and James Hardie siding products. The material choice depends on your lot, your budget, and your finish preferences. We prefer board-and-batten with fiber cement in coastal neighborhoods like Naples and Belmont Shore because it holds up to salt air far better than vinyl. For a full material breakdown on your project, call (562) 362-3885.
We can. Factory-built units from companies like Plant Prefab and Abodu are assembled off-site and craned or trucked onto your lot, which can compress the timeline meaningfully. Long Beach's permitting process treats prefab ADUs the same as site-built ones, so you still need plans, foundation permits, utility connections, and inspections. The prefab route works best on flat, accessible lots with street or alley access for delivery. We're honest about when a prefab makes sense and when site-built is better. Call (562) 362-3885 and we'll compare both paths for your lot.
In Long Beach's salt air and strong coastal sun, we recommend James Hardie fiber cement siding most of the time. It holds paint longer than wood, doesn't warp like vinyl in coastal heat, and stands up to the marine layer that rolls through neighborhoods like Belmont Park and the Peninsula. Inland areas like Signal Hill or Lakewood have less salt exposure, so options broaden. The right choice matches your main house anyway: if your existing home is stucco, we'll likely match it. Call (562) 362-3885 and we'll walk your exterior and recommend a real match.

Yes. We regularly take on ADU projects that other contractors started and walked away from, or that were built without proper permits and need to be brought up to code. In Long Beach, unpermitted ADUs are common, especially garage conversions from decades ago. The path forward often requires a code compliance review, selective demolition, and new plans. We can assess what you have in an afternoon and give you a written price to make it right. Call (562) 362-3885 to schedule a site visit.
