What Is Seattle Infill Development?
Infill development is the construction of new housing on underutilized or vacant parcels within already-developed urban areas — not on the suburban fringe. Rather than sprawl, infill adds density where infrastructure already exists: sewer, water, transit, and schools.
In Seattle, infill takes several forms:
- DADUs and ADUs — Detached and attached accessory dwelling units built on existing residential lots. Post-2019 ADU reform removed owner-occupancy requirements and off-street parking minimums, significantly expanding the viable site universe.
- Single-family replacement — Teardown and rebuild on underimproved lots, often capturing significant value uplift versus listing the property as-is.
- Cottage housing — Small-lot clustered development under SDCI’s cottage housing code, allowing multiple detached units on a single parcel.
- Short-plat subdivisions — Splitting larger lots into two or more buildable parcels, each capable of supporting independent development.
- Small-scale multifamily — 4–12 unit townhome developments on lots zoned LR1, LR2, or LR3, often structured as condominiums for individual unit sales.
Seattle’s Comprehensive Plan, MHA upzones, and ongoing ADU reform have significantly expanded the opportunity set for infill operators since 2019. The city’s 2024 One Seattle Comprehensive Plan update continues that trajectory, with additional density allowances in urban villages and station area overlays. Housing Affordability) upzones, and ongoing ADU reform have significantly expanded the opportunity set for infill operators since 2019.
Who We Help
Homeowners
You may be sitting on more value than a traditional sale would capture. We evaluate whether your property has redevelopment potential — DADU feasibility, short-plat eligibility, teardown value — before you make any decision.

Source better lots, structure construction financing through an in-house lender, and bring projects to market through a brokerage that specializes in new construction sellouts.
Developers
Acquire, entitle, build, and sell infill projects more efficiently. Specialty Real Estate Group’s vertical integration means one point of contact across brokerage, construction, and lending — no referral friction, no information gaps between your team members.

Adrian Chu’s Infill Development Approach
Adrian operates across every phase of the development cycle:
1. Site acquisition
Specialty Real Estate Group’s brokerage platform and 15+ years of Seattle market relationships provide off-market deal flow that most developers cannot access. Adrian evaluates parcels for lot coverage, setback configurations, FAR, tree canopy, soil conditions, and permitting risk before making offers.
2. Entitlement and design
Specialty Design+Build manages the design and permit process in-house. Adrian has direct experience navigating Seattle Department of Construction & Inspections (SDCI) permitting for infill projects, including boundary line adjustments (BLAs), short plats, condo maps, and lot segregations under SMC Title 22.
3. Construction
Specialty Design+Build serves as general contractor on all SREG-developed projects. The team currently delivers a number of homes annually, with a focus on infill typologies: DADUs, SFR replacements, and townhome clusters.
4. Financing
Specialty Home Loans (NMLS #2154241) provides in-house construction and permanent financing across Washington, California, Oregon, Idaho, Texas, and Florida. Adrian holds individual MLO license #920749. Access to in-house lending reduces friction on acquisition financing and construction draws.
5. Sales and sellout strategy
Specialty Real Estate Group handles all new construction listings. Adrian has developed proprietary sequencing strategies for multi-unit sellouts — managing pricing, DOM, and inter-unit competition across projects ranging from single family homes, 2-unit condo-mapped developments to 12-unit townhome clusters.
6. Property management (optional hold)
Laurelhurst Property Management provides ongoing management for projects that are held rather than sold, including rent-controlled units in San Francisco and long-term hold assets in the Puget Sound.
Seattle Infill Development FAQ
What does it cost to build a DADU in Seattle?
DADU construction costs in Seattle currently range from $250,000–$400,000+ depending on size, site conditions, and finish level, plus soft costs (design, permit, engineering). Specialty Design+Build delivers DADUs at competitive cost basis given in-house GC and permitting experience.
How long does a DADU permit take in Seattle?
SDCI DADU permits currently run 2-12+ months depending on lot complexity, tree canopy review, and whether a pre-application conference is required. ADU-eligible lots with no tree conflicts or environmentally critical areas move faster.
Can I build a DADU on my lot?
Most Seattle single-family lots (NR zoned and above) are DADU-eligible under post-2019 ADU code reform. Key factors include lot size, lot coverage, setbacks, existing structure height, and utility service capacity. SREG can assess your parcel..

Why a Vertically Integrated Platform Matters for Infill
Most infill developers operate as one node in a chain — buying from brokers, hiring outside GCs, using third-party lenders, and selling through listing agents. Each handoff creates friction, cost, and information asymmetry.
At Specialty Real Estate Group, vertical integration means:
- Brokerage, construction, lending, and property management share deal intelligence
- No referral fees bleed out of the project margin
- Permitting, design, and construction are coordinated under one decision-maker
- Lending can flex to match deal structure (construction-to-perm, bridge, DSCR)
This model — common at institutional scale, rare at the boutique level — is what allows Specialty Real Estate Group to operate at a number of homes per year while maintaining direct principal involvement on every project.
