Overview

This page explains what the Mountain House municipal zoning and development ordinance requires for landscaping and screening (trees, buffers, fences, walls, berms), where those rules are different by district, and how the Review Authority applies them. It summarizes the controlling rules in plain English and points to the exact code sections you must read and cite when preparing plans. See the city's general zoning overview for context on mapping and use categories. Mountain House Zoning

Key rules, short form

All mandatory landscape work must follow the water-efficient planting and irrigation rules in § 9-10-503.
Standard height limits for fences/screens in required yards are 3 ft (front/street-side) and 7 ft (rear/non-street-side) per § 9-10-602.
Screening options include plant materials, fencing, walls, or berms; prohibited materials include corrugated metal/plastic and unsecured chain-link except in narrowly allowed commercial/industrial cases (§ 9-10-604).
Street tree spacing, location and timing (installation before final inspection) are in § 9-10-504.
When a non-residential use abuts residential zoning the code generally requires a solid masonry wall 6–7 ft in height (§ 9-10-604(d)/(e)).

District-by-district breakdown

Notes on labels used in the code: the ordinance uses Very Low Density (R-VL), Rural Residential, Low Density (R-L), Medium Density (R-M), Medium‑High Density (R-MH), High Density (R-H), plus commercial, industrial, agricultural, planned developments, and mobile home parks. The specific landscaping/screening rules that follow are drawn from the cited ordinance sections.

Residential — R-VL, Rural Residential, R-L, R-M, R-MH, R-H

Purpose & typical uses: housing-focused zones (single-family, duplexes or multi-family per the zone); landscaping requirements aim to preserve natural features and provide street trees and privacy buffers. See the residential-specific requirements in § 9-10-506.
Key landscaping/screening standards:
- Street trees: one tree per lot frontage or max 60 ft spacing; Rural Residential requires 3 trees per frontage; trees must be 5-gallon at planting and installed before final inspection (§ 9-10-504).
- Fence height exceptions: general yard height caps are 3 ft front / 7 ft rear/non-street-side (§ 9-10-602), but the code allows special permits or siting exceptions:
  - Rural Residential and R-VL: open fence up to 7 ft in any required yard (§ 9-10-603(c)(1)).
  - R-L and R-M reverse-corner streetside: up to 7 ft if set back 10 ft from property line; cul‑de‑sac knuckles: up to 6 ft if set back 5 ft (§ 9-10-603(c)(B–C)).
  - R-MH and R-H: front and streetside yards may allow up to 7 ft fences if set back 10 ft from the property line (§ 9-10-603(c)(E)).
- Multifamily: projects of 5+ units must landscape all non-building areas and preserve natural features (§ 9-10-506(a)).

Where it applies: town neighborhoods and subdivisions that carry the named R-* designations; verify actual zone on the official map. Mountain House Land Use

Planned Developments — PD

Purpose & typical uses: flexible master-planned projects that may mix residential densities and open space; PDs have heightened landscape standards. See § 9-10-506(c).
Key dimensional/landscape standards:
- Tree count: the site must provide trees equal to at least twice the number of dwelling units (commonly stated as minimum two (2) trees per dwelling unit, excluding street & erosion-control trees) and tree planting specifications apply; see § 9-10-506(c)(1) and related PD landscaping plan rules.
- Landscape plan: PDs require a landscaping plan prepared by a licensed landscape architect showing plantings, irrigation, fencing, screening, grading and specifications (§ 9-10-506(c)(3)).
- Tree sizes: PD text also references minimum nursery size for some project trees; verify size standards and Review Authority allowances when preparing plans. Verify with the jurisdiction.
Where it applies: PD overlay areas and specific plan developments; check the PD conditions of approval. Mountain House Overlay Districts

Commercial — (Community Commercial, etc.)

Purpose & typical uses: retail, office, service uses adjacent to streets and neighborhoods.
Key landscaping/screening standards:
- All non‑built areas must be landscaped; provide at least a 10‑ft planting strip adjacent to streets (continuous except for driveways/walkways) — § 9-10-507(a).
- If abutting residential zones, a solid masonry wall 6–7 ft high is required along the property line (§ 9-10-604(d)(1)).
- Storage and trash areas must be screened to the height of 6–7 ft so they are not visible from streets/residences (§ 9-10-604(d)(2)).
- Landscape around parking: parking lots are to be surrounded by mature hedges/shrubs/berms and include planting islands sized for tree survival; protective curbing is required where planting abuts parking stalls (§ 9-10-503; § 9-10-503(e)).
Where it applies: properties zoned for commercial uses; check specific commercial zone (C‑C, etc.) for additional standards. Mountain House Signage

Industrial — (I‑G, etc.)

Purpose & typical uses: warehouses, distribution, manufacturing.
Key landscaping/screening standards:
- All non‑built areas not used for approved outdoor storage etc. must be landscaped; 10‑ft planting strip required along adjacent streets (§ 9-10-508(a)).
- When abutting residential, code requires a solid masonry wall 6–7 ft along the shared property line (§ 9-10-604(e)(1)). Storage areas normally must be screened to 6–8 ft and items within 100 ft of a street/residential zone cannot be stacked more than 2 ft above the adjacent screen (§ 9-10-604(e)(2)(A)).
- Security and special fencing rules (barbed wire, electrified fences) are heavily restricted next to residential and controlled by specific sections (§ 9-10-603(b), § 9-10-607).

Agricultural zones

Purpose & typical uses: farming, large-lot rural uses.
Key fencing/landscape standards:
- Open fence up to 7 ft in any required yard; parcels ≥ 20 acres may allow 8 ft open fences in side/rear yards; barbed wire on top is allowed up to 2 ft (subject to director discretion) (§ 9-10-603(f)).

Mobile Home Parks

Special rules: mobile home parks require a 6 ft masonry wall along rear and side property lines, 10‑ft landscaped strips along roads, and landscaping must conform to the general planting and screening standards (§ 9-10-908 referencing § 9-10-602/604).

Most decision-relevant standards (quick table)

Topic	Key rule / limit	Where to read (code reference)
Water‑efficient landscaping required for new landscaping	All new landscaping must be planned as water efficient; design uses plant-use value calculations	§ 9-10-503
Street trees (residential)	Max 60 ft spacing or 1 tree per frontage; 5‑gal min size; installed before final inspection	§ 9-10-504
Fence/screen height (required yards)	3 ft front/street side; 7 ft rear/non-street side (measured from higher grade)	§ 9-10-602
Fence materials — prohibitions	No corrugated plastic/iron/steel/aluminum/asbestos; chain-link security limited and must be landscaped	§ 9-10-604(b)
Commercial/industrial abutting residential	Solid masonry wall 6–7 ft along abutting property lines	§ 9-10-604(d)/(e)
Planting strips along streets (comm/industrial)	10 ft minimum planting strip along adjacent streets	§ 9-10-507, § 9-10-508
PD tree requirement	Trees equal at least twice the number of dwelling units (commonly stated as 2 trees/unit)	§ 9-10-506(c)
Heritage and native oak protection	No grade changes within 6 ft of trunk; protective fencing and planting limits in tree protective zone	§ 9-15-205 – § 9-15-206

Practical guidance & interpretation (plain-English synthesis)

If you are designing a subdivision, PD, commercial or industrial site, start your landscape plan to show planting islands, a continuous 10‑ft planting strip along streets (for non-residential), and the street‑tree layout required by § 9-10-504. Failure to show timing and irrigation details will delay Certificate of Occupancy because required landscaping/irrigation must be installed before final inspection unless the Director grants a delay (§ 9-10-503(f)).
For privacy or visual buffering to a neighboring house, you can use plant material, a fence, wall, or berm, but certain materials are prohibited and plant screens must achieve effective density in 3 years or be replaced (§ 9-10-604(b–c)).
Front yard fences: the default is 3 ft, but the code lists location-based exceptions allowing taller fences if set back from the property line (see the variety of residential exceptions in § 9-10-603(c)). If you want a taller front/street‑side fence, present that dimension and setback clearly on the plan and reference the specific residential exception that applies.
If your site borders residential zoning and is commercial/industrial, prepare to show a 6–7 ft masonry wall and screening for service/roof equipment and storage areas, per § 9-10-604(d–e).
For projects near protected oaks, follow the tree protection constraints (no grading within 6 ft of trunk, no trenching, protective fencing during construction) — these rules are mandatory and frequently enforced at plan-check § 9-15-205–206.

Also coordinate landscaping with: street design and public frontage responsibilities in the site’s Specific Plan or Mountain House CSD Design Manual, required parking layouts (affecting planting islands and curbs) and any applicable overlay design rules.

Checklist

Include a Landscape Plan that shows plant palette, hydrozones, tree species and spacing, irrigation zones, mulch, and planting details as required by § 9-10-506(c) / § 9-10-503.
Show street tree locations and sizes: max 60 ft spacing / 5‑gal minimum, outside ROW 4–10 ft from ROW per § 9-10-504.
If abutting residential, show 6–7 ft masonry wall (material note) and screening details per § 9-10-604(d/e).
Dimension fences in relation to property lines and confirm any setback exceptions used (e.g., 10 ft setback for front-yard 7 ft fences in certain residential zones) per § 9-10-603(c).
Provide irrigation plans showing automatic systems and rain switches; avoid irrigation that causes runoff (§ 9-10-503(c)).
For projects with protected oaks, include tree-protection fencing, no‑grade zones, and special irrigation/paving per § 9-15-205–206.
Show protective curbs/wheel stops where planting abuts parking (§ 9-10-503(e)).

Risks & Ambiguities

Issue	Why it matters	What to verify
Taller front-yard fence is needed	Default front/street‑side cap is 3 ft; exceptions exist but are location-specific	Confirm which residential exception applies and cite § 9-10-603(c); verify setback details on plan.
Chain‑link / security fencing	Chain‑link and barbed wire are largely prohibited unless landscaped/approved for commercial/industrial uses	If proposing chain‑link or barbed wire, confirm approval conditions under § 9-10-604(b) and § 9-10-603 and get Director sign‑off.
Heritage/native oak proximity	Construction/grading inside dripline triggers strict protections and may block improvements	Provide tree protection plan per § 9-15-205–206; verify allowed irrigation types and setbacks.
Conflicting measurement of fence height on sloped lots	Height is measured from the higher grade between lots or from the lowest side along arterials; errors create noncompliance	Use § 9-10-602(b) measurement rules on construction documents and call out grade datum.
Plant species & water‑use categories	City maintains a plant list and water‑use factors affect compliance	Use City plant list and design water‑use calculations per § 9-10-503(a)(2); consult Director for list and exceptions.

Plain-English Summary

Mountain House requires water‑efficient, inspected landscaping for new commercial, industrial, multifamily, PDs and many residential projects; fences and screens are limited by yard type (3 ft front / 7 ft rear) but the code lists many permitted exceptions by residential, commercial, industrial and agricultural zone; commercial/industrial projects abutting housing typically need a 6–7 ft masonry wall and dense screening. Read and design to § 9‑10‑503, § 9‑10‑602–604, § 9‑10‑504, and § 9‑10‑506(c) before submitting plans. filefilefilefile

Frequently asked questions

What are the basic fence height limits for a home in Mountain House?

Default yard limits are 3 ft in required front or street‑side yards and 7 ft in required rear or non‑street side yards; exceptions for particular residential zoning situations are listed in § 9-10-602 and § 9-10-603(c) (e.g., some zones permit taller fences if set back from the property line). file

Do commercial properties need a wall where they meet homes?

Yes — if a commercial project abuts a residential zone or a parcel designated for residential use, the code generally requires a solid masonry wall 6–7 ft high along that property line and dense screening for storage/trash areas; see § 9-10-604(d).

How many trees does a Planned Development need?

Planned Developments must provide trees equal to at least twice the number of dwelling units (commonly two trees per unit), and prepare a landscape plan by a licensed landscape architect showing locations, irrigation and specifications — see § 9-10-506(c).

When must landscaping and irrigation be installed?

All required landscaping and irrigation must be installed prior to issuance of the Certificate of Occupancy or final inspection unless the Director grants a delay; timing rules are in the landscaping chapter (§ 9-10-503(f)).

Are there prohibited materials for screening and fences?

Yes — the code prohibits screening made of corrugated plastic/iron, certain metals, asbestos, and similar; security chain‑link is generally prohibited except for limited commercial/industrial uses when combined with landscaping; barbed wire and slats are generally not allowed next to residences (§ 9-10-604(b)).

Do street trees have rules I must follow?

Yes — for new residential developments street trees must be spaced no more than 60 ft apart or at least one tree per lot frontage (Rural Residential requires 3 trees per lot frontage); trees must be 5‑gallon at planting and installed before final inspection. See § 9‑10‑504.

Can I use a berm instead of a wall for screening?

Yes — screening may include berms and an earth berm can count toward required height (with slope limits and maintenance access). The general screening options (planting, fencing, walls, berms) and earth‑berm rules are in § 9-10-604(a–b) and the planting/berm slope limits in § 9-10-503(b). file

Are there extra rules for protecting oak trees during construction?

Yes — you must avoid grading and trenching in the protected zone (no grade changes within 6 ft of a trunk, no trenching) and install protective fencing before grading; see the Heritage Oak protections § 9-15-205 and related landscaping restrictions § 9-15-206.

Who approves exceptions (e.g., taller walls for noise attenuation)?

The Director or Review Authority can modify or waive certain yard/height limits when necessary for effective noise attenuation or if an alternative meets the chapter’s intent; see § 9-10-605 (noise walls) and § 9-10-606 (modification of requirements). Verify specific approvals with the Review Authority and apply for the listed appeal procedures. file

Do I need a licensed landscape architect to submit a landscape plan?

Large‑scale projects and Planned Developments require landscape plans prepared by a licensed landscape architect; otherwise the Director may require a prepared plan when landscaping is required (§ 9-10-503(j) and § 9-10-506(c)(3)). file
