Buildable land on Seattle’s Eastside is in high demand and short supply. With strict zoning laws and environmental protections, even if you find land that looks perfect for your custom home, there may be significant restrictions or building limitations thanks to Washington State’s tough regulations.

Because vacant land is rare and often cost-prohibitive on the Eastside, most successful custom builds happen on infill lots, which are lots with an existing home that can easily be removed. These properties have proven buildability and offer the best combination of location, infrastructure, and value. JayMarc Custom Homes specializes in these opportunities, where utilities and access already exist, and teardown costs are minimal.

Even with an existing structure, what appears to be a dream property can hide expensive challenges, and in Washington’s buyer-beware market, it’s up to you to do the homework before you buy. With more than 300 homes built across the Eastside Seattle area, JayMarc Custom Homes can help you evaluate your prospective lot before you commit, so you can buy with confidence and clarity.

Why a Buildable Lot Isn’t Always What It Seems

Empty doesn’t always mean buildable, and “existing home” doesn’t always mean ready to rebuild. Many parcels can have underlying conditions that affect what and where you can build, like zoning limits, slopes, protected trees, and access to utilities. What looks like a simple teardown can become complicated if setbacks, easements, or environmental protections limit usable space.

Each Eastside municipality, whether it’s Bellevue, Kirkland, Redmond, or peripheral areas governed by King County, has specific rules, setbacks, and permitting timelines. JayMarc’s Red Flag Review can help you identify issues before you buy. Using online tools, city databases, and over 15 years of local experience, we offer an expert look at your chosen property’s potential. This early insight can identify major concerns such as critical slopes, wetland buffers, or restrictive zoning, before a purchase is finalized.

A complete feasibility study with surveys, geotechnical reports, and environmental studies, happens after closing, during JayMarc’s detailed Preconstruction Planning Process. This two-phase approach balances speed with security, offering quick insights early, and detailed certainty once you own the lot.

Defining Your Custom Home Goals Before You Buy

Before you buy land, or a potential teardown, it’s important to define your goals and understand how the vision for your home aligns with what the land can realistically support. Identify your non-negotiables early on, like views, privacy, or room for a covered patio

Your home’s design, size, and layout should guide your search. A lot that’s perfect for one style may not suit another. For example, a narrow or sloped property may not accommodate a rambler or a large outdoor living area. Some neighborhoods limit home height or style, while others have HOA requirements that influence design.

JayMarc Custom Homes can help you clarify your goals upfront, matching your vision and budget to the right property type so the lot you purchase aligns with what you actually want to build, not just what looks good on paper.

Real Factors That Determine If a Lot Is Buildable

Shape, Slope, and Site Conditions

The lot’s topography determines much of what can be built. Flat lots typically cost less to prepare, while steep slopes require engineering and retaining walls. Tree protection zones, wetlands, and setbacks can all limit usable area. Even if an existing home stands on the property now, the new construction will need to abide by current environmental and zoning rules, which may be different than when the lot was originally developed.

Utilities and Infrastructure

Existing homes often come with established utility connections, which is an advantage over raw land. Access to sewer, water, power, and gas reduces costs and eliminates the need for new infrastructure permits. Still, older connections and infrastructure may need updating, like power transformers, water meters, or septic systems.

Zoning, Setbacks, and Restrictions

City-specific zoning codes define how large your home can be, its height, and where it can sit on the lot. JayMarc’s Red Flag Review identifies these factors early, helping buyers avoid lots that don’t support the footprint of their dream home.

Permitting timelines vary widely across cities, from 4 months to over 1 year, so it’s important to plan ahead with a builder who understands each jurisdiction’s nuances.

Legal & Financial Due Diligence

Title reports, surveys, and recorded easements often reveal critical details that affect buildability. While areas and neighborhoods have rules that apply generally to everyone, the title report describes lot-specific information like easements, view restrictions, and HOA compliance. JayMarc helps clients uncover these issues, if any, before they commit.

Top Questions to Ask Before Buying Land (or a Tear-Down)

Whether you’re eyeing a vacant parcel or a teardown opportunity, asking the right questions will help you find the best property for your custom home project, without costly surprises down the road:

  1. How long has the property been on the market, and why hasn’t it sold? If a property has been on the market for an extended time and has not sold, it may indicate permitting issues, access problems, or hidden challenges.
  2. Has the property been appraised or compared to recent sales in the area? Market value impacts financing, equity, and long-term investment return. It’s important to request an appraisal before finalizing your offer, especially if one hasn’t been recently completed.
  3. What is the zoning classification and maximum buildable square footage and impervious surface limits, and has the city confirmed the parcel’s buildable status under current codes? This defines what type of structures can be built, maximum heights, and land-use limits, and will confirm whether or not your custom home can actually be permitted and constructed as planned. Before finalizing your purchase, always verify with the city or a land-use consultant that the parcel’s buildable status is current and compliant.
  4. Has the property undergone subdivision or boundary adjustments? Subdivision or boundary changes can affect the legal description, access, setbacks and utility easements of a property which can limit where and how you can build.
  5. Has a recent land survey been completed? Surveys verify boundaries, reveal encroachments, and confirm whether fences, driveways, or trees cross lot lines. Completing a current land survey before closing helps protect your investment and avoid boundary disputes.
  6. Are there any recorded easements, right-of-ways, or title issues? A clear title is essential! Utility easements or shared driveways can affect home placement and privacy, and title issues, liens, or ownership complications can lead to hidden financial or legal claims.
  7. Are utilities active and separate, or shared with neighboring lots, and will extensions be required? Confirm utility connections early to avoid unexpected construction costs, and verify that the utility services on your property are independent, not shared with adjacent lots. Missing sewer, water, or power stubs can add tens of thousands of dollars and could cause permitting delays.
  8. Is the lot easily accessible for construction vehicles and deliveries? Narrow or steep driveways and limited turnaround space can make construction more difficult and costly. Confirm that your lot can be easily accessed without adding temporary access routes or grading adjustments.
  9. Does the city provide trash pickup, mail service, and other utilities? Some semi-rural areas may require private arrangements for these services. Verify that your property will have all essential services and utilities in place to prevent last-minute surprises.
  10. Is the lot part of an HOA or subject to private neighborhood covenants? Private covenants and HOAs may have architectural guidelines, design approvals, and landscaping rules that limit design flexibility. Confirm your custom home plans with community guidelines before committing to a purchase.

JayMarc’s Red Flag Review helps you get early clarity on these points so you can make a confident, informed decision before purchase.
