Who Is the 1 Bed 650 Designed For?

The 1 Bed 650 is our most popular model because it gives renters genuine living space — not just a functional box. At 650 sq ft, there's room for a real kitchen, a proper dining area, a comfortable living room, and a bedroom that feels private. That quality of space attracts longer-term tenants, commands higher rents, and generates lower turnover costs over time.

  • Homeowners who want the highest-quality tenant profile
  • Properties where lot size allows a slightly larger footprint
  • Long-term rental strategies with minimized turnover
  • Family members who will occupy the unit longer-term
  • Homeowners who may eventually use the ADU themselves

Common Questions

1 Bed 650 — Frequently Asked Questions

Why is the 1 Bed 650 the most popular ADU model?
It's the model where rental income, construction cost, and tenant quality intersect most favorably. At 650 sq ft, renters get genuine living space — which means longer leases, lower turnover, and higher-quality tenants. The incremental cost over a 500 sq ft unit is modest relative to the rental income improvement.
What rental income can a 1 Bed 650 generate in LA?
In most Los Angeles markets, a well-finished 1 Bed 650 achieves $2,600–$3,600/month on a long-term lease. In higher-demand areas, $3,500–$4,500+/month is common. Annual gross rental income of $31,000–$54,000 is realistic for most LA neighborhoods.
Can the 1 Bed 650 be two stories?
Yes. For properties where a two-story footprint better suits the lot — for example, preserving backyard space — we can design the 1 Bed 650 as a two-story structure, spreading the square footage vertically. Height and setback rules vary by jurisdiction and we assess this during the property evaluation.
What's included in the 'Most Popular' designation?
It's simply the model our clients select most often after the free property assessment. The combination of livability, rental income potential, and construction value makes it the most common recommendation from our design team for standard LA lots.

ADU Build LA holds an active California General Contractor (B) license with CSLB and carries full general liability and workers' compensation insurance. Every subcontractor on your project is licensed, insured, and verified before they set foot on your property.

200+ ADUs Built Across LA County

We've completed over 200 ADU projects — garage conversions, detached new construction, Junior ADUs, and attached units — across every major LA-area city. That depth of experience means we've seen every site condition, every permit challenge, and every construction scenario.

15+ Years of ADU Experience

Since before the 2020 ADU law reforms, we've been building accessory dwelling units in Los Angeles. We've navigated every iteration of state ADU law, local zoning changes, and city permit process updates — institutional knowledge that directly accelerates your project.

Transparent, Fixed-Price Contracts

We don't use time-and-materials billing or open-ended design fees. Every project starts with a detailed all-inclusive fixed price covering design, engineering, permitting, and construction. What we quote is what you pay — no surprise change orders, no scope creep billing.

In-House Permit Management

Our team has submitted hundreds of permit applications across LADBS, Santa Monica, Pasadena, Glendale, Culver City, and other LA-area jurisdictions. We know each city's plan check process, common correction triggers, and expedite options — reducing wait time and managing every step for you.

Single-Contract Design-Build

Under one contract, our in-house team handles every phase — design, engineering, permitting, and construction. You won't need to coordinate between a separate architect and a separate builder. One point of contact, one schedule, full accountability from first sketch to final inspection.
