1. a

   Permit authority & plan check days

   Inglewood Economic & Community Development is the issuing jurisdiction. Plan-check window of 80–130 days reflects our last twelve submittals here for code-compliant ADU sets; complex sites (hillside, historic, coastal) trend longer. Verified against the jurisdiction's published service-level targets where available.

2. b

   Median lot size

   Modeled from LA County Assessor parcel records (APN database) for R-1 and R-2 zoned residential parcels in the Inglewood city limits. Excludes commercial, multi-family ≥4 units, and parcels under 2,500 sq ft. Median, not mean — large estate lots do not skew the figure.

3. c

   1-BR & 2-BR rents

   90-day trailing median asking rent for ADU-equivalent units (detached cottages, in-law suites, garage conversions) within the Inglewood ZIP codes, blended across Zillow Rent Index, Apartments.com, and RentCafe. Excludes furnished short-term listings.

4. d

   Starting price & cost / sq ft

   Firm. Averaged from our last 24 months of signed contracts for comparable scope (Inglewood or adjacent submarket). Includes design, permits, construction, and standard finish package; excludes site-specific utility upgrades (see permit notes) and owner-furnished appliances. Quoted from $140K.

5. e

   Estimated annual ROI

   Modeled as (annual gross rent − operating expenses) ÷ all-in project cost. Assumes 95% occupancy, 8% opex (insurance, maintenance, vacancy reserve), and the 2-BR rent above. Does not include appreciation, tax benefits, or financing leverage — those typically add 3–6 points. Published range of 12–16% reflects floor and ceiling scenarios.

Numbers refresh quarterly. For a binding figure on your specific parcel, request a feasibility letter — we'll pull live permit history, utility records, and comps within 48 hours.

   Does SB-9 apply to my Inglewood lot?

   +
   SB-9 (the California HOME Act) lets eligible single-family lots split into two parcels and/or add a duplex. We assess eligibility during the feasibility call — roughly 60% of LA single-family lots qualify on paper, fewer in practice once HPOZ, hillside, and coastal overlays are applied. SB-9 projects can stack with an ADU for up to four units on what was a single-family lot.
