In San Elijo Hills, Lake San Marcos, Discovery Hills, Rancho Tesoro, Twin Oaks Valley, Santa Fe Hills, Old Creek Ranch, Rancho Dorado and the University District (CSUSM), we design‑build cohesive outdoor living: porcelain/paver patios, louvered pergolas or engineered pavilions, masonry outdoor kitchens (gas/electric), retaining/seat walls & hillside steps, low‑glare lighting, drainage/underdrains, turf & putting greens, planting/irrigation—coordinated with City of San Marcos permits; for Lake San Marcos parcels (unincorporated), we route through County PDS/DPW.
Project fit: Minimum project $15k. Typical San Marcos backyard packages run $95k–$200k+. Whole‑property (front + back) plans often range $200k–$600k+. Hillside/engineering‑heavy builds may exceed $300k–$750k+ based on grading, utilities and approvals.

Key Takeaways
- Right jurisdiction, right away: City of San Marcos for most addresses; Lake San Marcos is unincorporated (County PDS + DPW). We verify before design.
- Family‑friendly, high‑finish builds: Shade, privacy, wind control and great circulation tailored to 92069/92078 lot sizes.
- Clear ranges, fewer surprises: Transparent packages and line‑item allowances (gas/electric, drainage, engineering) prevent change‑order creep.
Do‑This‑First — Jurisdiction, Hillsides & Utilities
- Jurisdiction check: Most neighborhoods are City of San Marcos (Building Division). Lake San Marcos addresses are typically County of San Diego (PDS Building; DPW for ROW). We route accordingly.
- Overlays & landform: Hillside/ESL conditions (San Elijo/Discovery Hills), creek corridor constraints near San Marcos Creek, and WUI checks where applicable.
- ROW tie‑ins: Driveway aprons, sidewalk underdrains and curb outlets go through City Public Works/Encroachment (or County DPW in Lake San Marcos). We design private‑to‑public interfaces up front.
- Utilities: Confirm panel capacity (heaters, lighting, kitchen) and total gas BTU load; coordinate SDG&E upgrades/relocations if needed.
- Code cycle: 2022 CA Codes through Dec 31, 2025; 2025 codes effective Jan 1, 2026.

FAQs — San Marcos
Is Lake San Marcos in the City or County?
Most Lake San Marcos parcels are in unincorporated County jurisdiction. We handle County PDS building and DPW encroachment where applicable.
Who issues building permits?
For City addresses: City of San Marcos (Building Division). For Lake San Marcos: County of San Diego (PDS). We route your project to the correct agency.
Do I need HOA/ARC approval?
Many neighborhoods (San Elijo Hills, Rancho Tesoro, Old Creek Ranch) have HOAs with architectural review. We coordinate HOA approvals in parallel with City/County permits.
What about driveway aprons or curb outlets?
City Public Works manages Right‑of‑Way permits within San Marcos; County DPW manages ROW for Lake San Marcos. Maintenance/encroachment agreements may be required.
Can you design for slopes, privacy and wind?
Yes—pavilions/louvered systems, privacy walls/screens, layered planting and hillside steps/terraces create usable zones and safe circulation.
